<h1 id="what-is-clink">What is Clink?</h1>
<p>Clink combines the native Windows shell cmd.exe with the powerful command line editing features of the GNU Readline library, which provides rich completion, history, and line-editing capabilities. Readline is best known for its use in the well-known Unix shell Bash, the standard shell for Mac OS X and many Linux distributions.</p>
<h1 id="features">Features</h1>
<ul>
<li>The same line editing as Bash (from the <a href="https://tiswww.case.edu/php/chet/readline/rltop.html">GNU Readline library</a> version 8.1).</li>
<li>History persistence between sessions.</li>
<li>Context sensitive completion;<ul>
<li>Executables (and aliases).</li>
<li>Directory commands.</li>
<li>Environment variables.</li>
</ul>
</li>
<li>Context sensitive colored input text.</li>
<li>New keyboard shortcuts;<ul>
<li>Paste from clipboard (<kbd>Ctrl</kbd>+<kbd>V</kbd>).</li>
<li>Incremental history search (<kbd>Ctrl</kbd>+<kbd>R</kbd> and <kbd>Ctrl</kbd>+<kbd>S</kbd>).</li>
<li>Powerful completion (<kbd>Tab</kbd>).</li>
<li>Undo (<kbd>Ctrl</kbd>+<kbd>Z</kbd>).</li>
<li>Automatic <code>cd ..</code> (<kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>U</kbd>).</li>
<li>Environment variable expansion (<kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>E</kbd>).</li>
<li>Doskey alias expansion (<kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>F</kbd>).</li>
<li>Scroll the screen buffer (<kbd>Alt</kbd>+<kbd>Up</kbd>, etc).</li>
<li><kbd>Shift</kbd>+Arrow keys to select text, typing replaces selected text, etc.</li>
<li>(press <kbd>Alt</kbd>+<kbd>H</kbd> for many more...)</li>
</ul>
</li>
<li>Directory shortcuts;<ul>
<li>Typing a directory name followed by a path separator is a shortcut for <code>cd /d</code> to that directory.</li>
<li>Typing <code>..</code> or <code>...</code> is a shortcut for <code>cd ..</code> or <code>cd ..\..</code> (each additional <code>.</code> adds another <code>\..</code>).</li>
<li>Typing <code>-</code> or <code>cd -</code> changes to the previous current working directory.</li>
</ul>
</li>
<li>Scriptable completion with Lua.</li>
<li>Scriptable key bindings with Lua.</li>
<li>Colored and scriptable prompt.</li>
<li>Auto-answering of the &quot;Terminate batch job?&quot; prompt.</li>
</ul>
<p>By default Clink binds <kbd>Alt</kbd>+<kbd>H</kbd> to display the current key bindings. More features can also be found in GNU&#39;s <a href="https://tiswww.cwru.edu/php/chet/readline/readline.html">Readline</a> and <a href="https://tiswww.cwru.edu/php/chet/readline/history.html">History</a> libraries&#39; manuals.</p>

<p>
<strong>Want some quick but powerful tips to get started?</strong>
</p>
<p>
<table>
<tr><td><kbd>Ctrl</kbd>+<kbd>O</kbd></td><td>This is <code>operate-and-get-next</code>, which accepts the current input line and gets the next history line. You can search history for a command, then press <kbd>Ctrl</kbd>+<kbd>O</kbd> to run that command and queue up the next command after it. Repeat it to conveniently rerun a series of commands from the history.</td></tr>
<tr><td><kbd>Alt</kbd>+<kbd>.</kbd></td><td>This is <code>yank-last-arg</code>, which inserts the last argument from the previous line. You can use it repeatedly to cycle backwards through the history, inserting the last argument from each line. Learn more by reading up on the "yank" features in the Readline manual.</td></tr>
<tr><td><kbd>Ctrl</kbd>+<kbd>R</kbd></td><td>This is <code>reverse-search-history</code>, which incrementally searches the history. Press it, then type, and it does a reverse incremental search while you type. Press <kbd>Ctrl</kbd>+<kbd>R</kbd> again (and again, etc) to search for other matches of the search text. Learn more by reading up on the "search" and "history" features in the Readline manual.</td></tr>
<tr><td><kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>D</kbd></td><td>This is <code>remove-history</code>, which deletes the currently selected history line after using any of the history search or navigation commands.</td></tr>
<tr><td><kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>K</kbd></td><td>This is <code>add-history</code>, which adds the current line to the history without executing it, and then clears the input line.</td></tr>
<tr><td><kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>N</kbd></td><td>This is <code>clink-menu-complete-numbers</code>, which grabs numbers with 3 or more digits from the current console screen and cycles through inserting them as completions (binary, octal, decimal, hexadecimal). Super handy for quickly inserting a commit hash that was printed as output from a preceding command.</td></tr>
<tr><td><kbd>Alt</kbd>+<kbd>0</kbd> to <kbd>Alt</kbd>+<kbd>9</kbd></td><td>These are <code>digit-argument</code>, which let you enter a numeric value used by many commands. For example <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>W</kbd> copies the current word to the clipboard, but if you first type <kbd>Alt</kbd>+<kbd>2</kbd> followed by <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>W</kbd> then it copies the 3rd word to the clipboard (the first word is 0, the second is 1, etc). Learn more by reading up on "Readline Arguments" in the Readline manual.</td></tr>
<tr><td><kbd>Alt</kbd>+<kbd>H</kbd></td><td>This is <code>clink-show-help</code>, which lists the key bindings and commands. Learn more by visiting <a href="#keybindings">Key Bindings</a>.</td></tr>
</table>
</p>
</blockquote>
<h1 id="usage">Usage</h1>
<p>There are several ways to start Clink.</p>
<ol>
<li>If you installed the auto-run, just start <code>cmd.exe</code>. Run <code>clink autorun --help</code> for more info.</li>
<li>To manually start, run the Clink shortcut from the Start menu (or the clink.bat located in the install directory).</li>
<li>To establish Clink to an existing <code>cmd.exe</code> process, use <code>&lt;install_dir&gt;\clink.exe inject</code>.</li>
</ol>
<h1 id="upgrading-from-clink-v049">Upgrading from Clink v0.4.9</h1>
<p>The new Clink tries to be as backward compatible with Clink v0.4.9 as possible. However, in some cases upgrading may require a little bit of configuration work.</p>
<ul>
<li>Some key binding sequences have changed; see <a href="#keybindings">Key Bindings</a> for more information.</li>
<li>Match coloring is now done by Readline and is configured differently; see <a href="#completioncolors">Completion Colors</a> for more information.</li>
<li>Settings and history should migrate automatically if the new <code>clink_settings</code> and <code>clink_history</code> files don&#39;t exist (deleting them will cause migration to happen again). To find the directory that contains these files, run <code>clink info</code> and look for the &quot;state&quot; line.</li>
<li>Script compatibility should be very good, but some scripts may still encounter problems. If you do encounter a compatibility problem you can look for an updated version of the script, update the script yourself, or visit the <a href="https://github.com/chrisant996/clink/issues">repo</a> and open an issue describing details about the compatibility problem.</li>
<li>Some settings have changed slightly, and there are many new settings. See <a href="#configclink">Configuring Clink</a> for more information.</li>
</ul>
<h1 id="how-clink-works">How Clink Works</h1>
<p>When running Clink via the methods above, Clink checks the parent process is supported and injects a DLL into it. The DLL then hooks the WriteConsole() and ReadConsole() Windows functions. The former is so that Clink can capture the current prompt, and the latter hook allows Clink to provide its own Readline-powered command line editing.</p>
<a name="privacy"/>
<h2 id="privacy">Privacy</h2>
<p>Clink does not collect user data. Clink writes diagnostic information to its local log file, and does not transmit the log file off the local computer. For the location of the log file, refer to <a href="#filelocations">File Locations</a> or run <code>clink info</code>.</p>
<a name="configclink"/>
<h1 id="configuring-clink">Configuring Clink</h1>
<p>The easiest way to configure Clink is to use Clink&#39;s <code>set</code> command line option. This can list, query, and set Clink&#39;s settings. Run <code>clink set --help</code> from a Clink-installed cmd.exe process to learn more both about how to use it and to get descriptions for Clink&#39;s various options.</p>
<p>The following table describes the available Clink settings:</p>

<p><code>[<span class="arg">attributes</span>] [<span class="arg">foreground_color</span>] [on [<span class="arg">background_color</span>]]</code></p>
<p>Optional attributes (can be abbreviated to 3 letters):</p>
<ul>
<li><code>bold</code> or <code>nobold</code> adds or removes boldface (usually represented by forcing the color to use high intensity if it doesn&#39;t already).</li>
<li><code>underline</code> or <code>nounderline</code> adds or removes an underline.</li>
</ul>
<p>Optional colors for <span class="arg">foreground_color</span> and <span class="arg">background_color</span> (can be abbreviated to 3 letters):</p>
<ul>
<li><code>default</code> or <code>normal</code> uses the default color as defined by the current color theme in the console window.</li>
<li><code>black</code>, <code>red</code>, <code>green</code>, <code>yellow</code>, <code>blue</code>, <code>cyan</code>, <code>magenta</code>, <code>white</code> are the basic colors names.</li>
<li><code>bright</code> can be combined with any of the other color names to make them bright (high intensity).</li>
</ul>
<p>Examples (specific results may depend on the console host program):</p>
<ul>
<li><code>bri yel</code> for bright yellow foreground on default background color.</li>
<li><code>bold</code> for bright default foreground on default background color.</li>
<li><code>underline bright black on white</code> for dark gray (bright black) foreground on light gray (white) background.</li>
<li><code>default on blue</code> for default foreground color on blue background.</li>

<h3 id="alternative-sgr-syntax">Alternative SGR Syntax</h3>
<p>It&#39;s also possible to set any ANSI <a href="https://en.wikipedia.org/wiki/ANSI_escape_code#SGR">SGR escape code</a> using <code>sgr <span class="arg">SGR_parameters</span></code> (for example <code>sgr 7</code> is the code for reverse video, which swaps the foreground and background colors).</p>
<p>Be careful, since some escape code sequences might behave strangely.</p>
<a name="filelocations"/>
<h2 id="file-locations">File Locations</h2>
<p>Settings and history are persisted to disk from session to session. The location of these files depends on which distribution of Clink was used. If you installed Clink using the .exe installer then Clink uses the current user&#39;s non-roaming application data directory. This user directory is usually found in one of the following locations;</p>
<ul>
<li>Windows XP: <code>c:\Documents and Settings\&lt;username&gt;\Local Settings\Application Data\clink</code></li>
<li>Windows Vista onwards: <code>c:\Users\&lt;username&gt;\AppData\Local\clink</code></li>
</ul>
<p>All of the above locations can be overridden using the <code>--profile <span class="arg">path</span></code> command line option which is specified when injecting Clink into cmd.exe using <code>clink inject</code>. Or with the <code>%CLINK_PROFILE%</code> environment variable if it is already present when Clink is injected (this envvar takes precedence over any other mechanism of specifying a profile directory, if more than one was used).</p>
<p>You can use <code>clink info</code> to find the directories and configuration files for the current Clink session.</p>

<h2 id="portable-configuration">Portable Configuration</h2>
<p>Sometimes it&#39;s useful to run Clink from a flash drive or from a network share, especially if you want to use Clink on someone else&#39;s computer.</p>
<p>Here&#39;s how you can set up a portable configuration for Clink:</p>
<ol>
<li>Put your Lua scripts and other tools in the same directory as the Clink executable files. For example fzf.exe, z.cmd, oh-my-posh.exe, or etc can all go in the same directory on a flash drive or network share.</li>
<li>Make a batch file such as <code>portable.bat</code> that injects Clink using a specific profile directory.<ul>
<li>On a flash drive, you can have a portable profile in a subdirectory under the Clink directory.</li>
<li>On a network share, you&#39;ll want to copy some initial settings into a local profile directory (a profile directory on a network share will be slow).</li>
</ul>
</li>
<li>In any cmd.exe window on any computer, you can then run the <code>portable.bat</code> script to inject Clink and have all your favorite settings and key bindings work.</li>
</ol>
<p>Here are some sample scripts:</p>
<h3 id="portablebat-on-a-flash-drive">portable.bat (on a flash drive)</h3>
<p>This sample script assumes the portable.bat script is in the Clink directory, and it uses a <code>clink_portable</code> profile directory under the Clink directory.</p>
<pre><code class="language-cmd">@echo off
rem -- Do any other desired configuration here, such as loading a doskey macro file.
call &quot;%~dp0clink.bat&quot; inject --profile &quot;%~dp0clink_portable&quot; %1 %2 %3 %4 %5 %6 %7 %8 %9
</code></pre>
<h3 id="portablebat-on-a-network-share">portable.bat (on a network share)</h3>
<p>This sample script assumes the portable.bat script is in the Clink directory, and that there is a file <code>portable_clink_settings</code> with the settings you want to copy to the local profile directory.</p>
<pre><code class="language-cmd">@echo off
if not exist &quot;%TEMP%\clink_portable&quot; md &quot;%TEMP%\clink_portable&quot; &gt;nul
if not exist &quot;%TEMP%\clink_portable\clink_settings&quot; copy &quot;%~dp0portable_clink_settings&quot; &quot;%TEMP%\clink_portable\clink_settings&quot; &gt;nul

call &quot;%~dp0clink.bat&quot; inject --profile &quot;%TEMP%\clink_portable&quot; %1 %2 %3 %4 %5 %6 %7 %8 %9
</code></pre>
<a name="configreadline"/>
<h1 id="configuring-readline">Configuring Readline</h1>
<p>Readline itself can also be configured to add custom keybindings and macros by creating a Readline init file. There is excellent documentation for all the options available to configure Readline in Readline&#39;s <a href="https://tiswww.cwru.edu/php/chet/readline/rltop.html#Documentation">manual</a>.</p>
<p>Clink searches in the directories referenced by the following environment variables and loads any <code>.inputrc</code> or <code>_inputrc</code> files present, in the order listed here:</p>
<ul>
<li><code>%CLINK_INPUTRC%</code></li>
<li>The Clink profile directory (see the &quot;state&quot; line from <code>clink info</code>).</li>
<li><code>%USERPROFILE%</code></li>
<li><code>%LOCALAPPDATA%</code></li>
<li><code>%APPDATA%</code></li>
<li><code>%HOME%</code></li>
</ul>
<p>Configuration in files loaded earlier can be overridden by files loaded later.</p>
<p>Other software that also uses Readline will also look for the <code>.inputrc</code> file (and possibly the <code>_inputrc</code> file too). To set macros and keybindings intended only for Clink one can use the Readline init file conditional construct like this; <code>$if clink [...] $endif</code>.</p>
<p>You can use <code>clink info</code> to find the directories and configuration files for the current Clink session.</p>
<blockquote>
<p><strong>Compatibility Notes:</strong></p>
<ul>
<li>The <code>clink_inputrc_base</code> file from v0.4.8 is no longer used.</li>
<li>For backward compatibility, <code>clink_inputrc</code> is also loaded from the above locations, but it has been deprecated and may be removed in the future.</li>
</ul>
</blockquote>
<h2 id="basic-format">Basic Format</h2>
<p>The quick version is that mostly you&#39;ll use these kinds of lines:</p>
<ul>
<li><code><span class="arg">keyname</span>: <span class="arg">command</span></code></li>
<li><code><span class="arg">keyname</span>: "<span class="arg">literal text</span>"</code></li>
<li><code><span class="arg">keyname</span>: "luafunc:<span class="arg">lua_function_name</span>"</code></li>
<li><code>set <span class="arg">varname</span> <span class="arg">value</span></code></li>
</ul>
<p>If a Readline macro begins with &quot;luafunc:&quot; then Clink interprets it as a Lua key binding and will invoke the named Lua function. Function names can include periods (such as <code>foo.bar</code>) but cannot include any other punctuation. See <a href="#luakeybindings">Lua Key Bindings</a> for more information.</p>
<p>Refer to the Readline <a href="https://tiswww.cwru.edu/php/chet/readline/rltop.html#Documentation">manual</a> for a more thorough explanation of the .inputrc file format, list of available commands, and list of configuration variables and their values.</p>
<p>See <a href="#keybindings">Key Bindings</a> for more information about binding keys in Clink.</p>

<h2 id="completion-colors">Completion Colors</h2>
<p>When <code>colored-completion-prefix</code> is configured to <code>on</code>, then the &quot;so&quot; color from <code>%LS_COLORS%</code> is used to color the common prefix when displaying possible completions. The default for &quot;so&quot; is magenta, but for example <code>set LS_COLORS=so=90</code> sets the color to bright black (which shows up as a dark gray).</p>
<p>When <code>colored-stats</code> is configured to <code>on</code>, then the color definitions from <code>%LS_COLORS%</code> (using ANSI escape codes) are used to color file completions according to their file type or extension. Each definition is a either a two character type id or a file extension, followed by an equals sign and then the <a href="https://en.wikipedia.org/wiki/ANSI_escape_code#SGR_parameters">SGR parameters</a> for an ANSI escape code. Multiple definitions are separated by colons. Also, since <code>%LS_COLORS%</code> doesn&#39;t cover readonly files, hidden files, doskey aliases, or shell commands the <code>color.readonly</code>, <code>color.hidden</code>, <code>color.doskey</code>, and <code>color.cmd</code> <a href="#configclink">Clink settings</a> exist to cover those.</p>
<p>Here is an example where <code>%LS_COLORS%</code> defines colors for various types.</p>
<ul>
<li><code>so=</code> defines the color for the common prefix for possible completions.</li>
<li><code>fi=</code> defines the color for normal files.</li>
<li><code>di=</code> defines the color for directories.</li>
<li><code>ex=</code> defines the color for executable files.</li>
</ul>
<pre><code class="language-plaintext">set LS_COLORS=so=90:fi=97:di=93:ex=92:*.pdf=30;105:*.md=4
</code></pre>
<p>Let&#39;s break that down:</p>
<ul>
<li><code>so=90</code> uses bright black (dark gray) for the common prefix for possible completions.</li>
<li><code>fi=97</code> uses bright white for files.</li>
<li><code>di=93</code> uses bright yellow for directories.</li>
<li><code>ex=92</code> uses bright green for executable files.</li>
<li><code>*.pdf=30;105</code> uses black on bright magenta for .pdf files.</li>

<h1 id="extending-clink">Extending Clink</h1>
<p>The Readline library allows clients to offer an alternative path for creating completion matches. Clink uses this to hook Lua into the completion process making it possible to script the generation of matches with <a href="https://www.lua.org/docs.html">Lua</a> scripts. The following sections describe this in more detail and show some examples.</p>
<a name="lua-scripts-location"/>
<h2 id="the-location-of-lua-scripts">The Location of Lua Scripts</h2>
<p>Clink loads all Lua scripts it finds in these directories:</p>
<ol>
<li>All directories listed in the <code>clink.path</code> setting, separated by semicolons.</li>
<li>If <code>clink.path</code> is not set, then the DLL directory and the profile directory are used (see <a href="#filelocations">File Locations</a> for info about the profile directory).</li>
<li>All directories listed in the <code>%CLINK_PATH%</code> environment variable, separated by semicolons.</li>
<li>All directories registered by the <code>clink installscripts</code> command.</li>
</ol>
<p>Lua scripts are loaded once and are only reloaded if forced because the scripts locations change, the <code>clink-reload</code> command is invoked (<kbd>Ctrl</kbd>+<kbd>X</kbd>,<kbd>Ctrl</kbd>+<kbd>R</kbd>), or the <code>lua.reload_scripts</code> setting changes (or is True).</p>
<p>Run <code>clink info</code> to see the script paths for the current session.</p>
<a name="matchgenerators"/>
<h2 id="match-generators">Match Generators</h2>
<p>These are Lua functions that are called as part of Readline&#39;s completion process.</p>
<p>First create a match generator object:</p>
<pre><code class="language-lua">local my_generator = clink.generator(priority)
</code></pre>
<p>The <span class="arg">priority</span> argument is a number that influences when the generator gets called, with lower numbers going before higher numbers.</p>
<h3 id="the-generate-function">The :generate() Function</h3>
<p>Next define a match generator function on the object, taking the following form:</p>
<pre><code class="language-lua">function my_generator:generate(line_state, match_builder)
-- Use the line_state object to examine the current line and create matches.
-- Submit matches to Clink using the match_builder object.
-- Return true or false.
end
</code></pre>
<p><span class="arg">line_state</span> is a <a href="#line">line</a> object that has information about the current line.</p>
<p><span class="arg">match_builder</span> is a <a href="#builder">builder</a> object to which matches can be added.</p>
<p>If no further match generators need to be called then the function should return true. Returning false or nil continues letting other match generators get called.</p>
<p>Here is an example script that supplies git branch names as matches for <code>git checkout</code>. It&#39;s based on git_branch_autocomplete.lua from <a href="https://github.com/collink/clink-git-extensions">collink.clink-git-extensions</a>. The version here is updated for the new Clink Lua API, and for illustration purposes it&#39;s been simplified to not support git aliases.</p>
<pre><code class="language-lua">local git_branch_autocomplete = clink.generator(1)
local function string.starts(str, start)
return string.sub(str, 1, string.len(start)) == start
end
local function is_checkout_ac(text)
if string.starts(text, &quot;git checkout&quot;) then
return true
end
return false
end
local function get_branches()
-- Run git command to get branches.
local handle = io.popen(&quot;git branch -a 2&gt;&amp;1&quot;)
local result = handle:read(&quot;*a&quot;)
handle:close()
-- Parse the branches from the output.
local branches = {}
if string.starts(result, &quot;fatal&quot;) == false then
for branch in string.gmatch(result, &quot; %S+&quot;) do
branch = string.gsub(branch, &quot; &quot;, &quot;&quot;)
if branch ~= &quot;HEAD&quot; then
table.insert(branches, branch)
end
end
end
return branches
end
function git_branch_autocomplete:generate(line_state, match_builder)
-- Check if it&#39;s a checkout command.
if not is_checkout_ac(line_state:getline()) then
return false
end
-- Get branches and add them (does nothing if not in a git repo).
local matchCount = 0
for _, branch in ipairs(get_branches()) do
match_builder:addmatch(branch)
matchCount = matchCount + 1
end
-- If we found branches, then stop other match generators.
return matchCount &gt; 0
end
</code></pre>
<h3 id="the-getwordbreakinfo-function">The :getwordbreakinfo() Function</h3>
<p>A generator can influence word breaking for the end word by defining a <code>:getwordbreakinfo()</code> function. The function takes a <span class="arg">line_state</span> <a href="#line">line</a> object that has information about the current line. If it returns nil or 0, the end word is truncated to 0 length. This is the normal behavior, which allows Clink to collect and cache all matches and then filter them based on typing. Or it can return two numbers: word break length and an optional end word length. The end word is split at the word break length: one word contains the first word break length characters from the end word (if 0 length then it&#39;s discarded), and the next word contains the rest of the end word truncated to the optional word length (0 if omitted).</p>
<p>For example, when the environment variable match generator sees the end word is <code>abc%USER</code> it returns <code>3,1</code> so that the last two words become &quot;abc&quot; and &quot;%&quot; so that its generator knows it can do environment variable matching. But when it sees <code>abc%FOO%def</code> it returns <code>8,0</code> so that the last two words become &quot;abc%FOO%&quot; and &quot;&quot; so that its generator won&#39;t do environment variable matching, and also so other generators can produce matches for what follows, since &quot;%FOO%&quot; is an already-completed environment variable and therefore should behave like a word break. In other words, it breaks the end word differently depending on whether the number of percent signs is odd or even, to account for environent variable syntax rules.</p>
<p>And when an argmatcher sees the end word begins with a flag character it returns <code>0,1</code> so the end word contains only the flag character in order to switch from argument matching to flag matching.</p>
<blockquote>
<p><strong>Note:</strong> The <code>:getwordbreakinfo()</code> function is called very often, so it needs to be very fast or it can cause responsiveness problems while typing.</p>
</blockquote>
<pre><code class="language-lua">local envvar_generator = clink.generator(10)
function envvar_generator:generate(line_state, match_builder)
-- Does the word end with a percent sign?
local word = line_state:getendword()
if word:sub(-1) ~= &quot;%&quot; then
return false
end
-- Add env vars as matches.
for _, i in ipairs(os.getenvnames()) do
match_builder:addmatch(&quot;%&quot;..i..&quot;%&quot;, &quot;word&quot;)
end
match_builder:setsuppressappend() -- Don&#39;t append a space character.
match_builder:setsuppressquoting() -- Don&#39;t quote envvars.
return true
end
function envvar_generator:getwordbreakinfo(line_state)
local word = line_state:getendword()
local in_out = false
local index = nil
-- Paired percent signs denote already-completed environment variables.
-- So use envvar completion for abc%foo%def%USER but not for abc%foo%USER.
for i = 1, #word do
if word:sub(i, i) == &quot;%&quot; then
in_out = not in_out
if in_out then
index = i - 1
else
index = i
end
end
end
-- If there were any percent signs, return word break info to influence the
-- match generators.
if index then
return index, (in_out and 1) or 0
end
end

<a name="argumentcompletion"/>
<h2 id="argument-completion">Argument Completion</h2>
<p>Clink provides a framework for writing complex argument match generators in Lua. It works by creating a parser object that describes a command&#39;s arguments and flags and then registering the parser with Clink. When Clink detects the command is being entered on the current command line being edited, it uses the parser to generate matches.</p>
<p>Here is an example of a simple parser for the command <code>foobar</code>;</p>
<pre><code class="language-lua">clink.argmatcher(&quot;foobar&quot;)
:addflags(&quot;-foo&quot;, &quot;-bar&quot;)
:addarg(
{ &quot;hello&quot;, &quot;hi&quot; }, -- Completions for arg #1
{ &quot;world&quot;, &quot;wombles&quot; } -- Completions for arg #2
)
</code></pre>
<p>This parser describes a command that has two positional arguments each with two potential options. It also has two flags which the parser considers to be position independent meaning that provided the word being completed starts with a certain prefix the parser with attempt to match the from the set of flags.</p>
<p>On the command line completion would look something like this:</p>
<pre style="border-radius:initial;border:initial"><code class="plaintext" style="background-color:black;color:#cccccc">C:&gt;foobar hello -foo wo
wombles wonder world
C:&gt;foobar hello -foo wo<span style="color:#ffffff">_</span>
</code></pre>
<p>When displaying possible completions, flag matches are only shown if the flag character has been input (so <code>command </code> and <kbd>Alt</kbd>+<kbd>=</kbd> would list only non-flag matches, or <code>command -</code> and <kbd>Alt</kbd>+<kbd>=</kbd> would list only flag matches).</p>
<h3 id="more-advanced-stuff">More Advanced Stuff</h3>
<h4 id="linking-parsers">Linking Parsers</h4>
<p>There are often situations where the parsing of a command&#39;s arguments is dependent on the previous words (<code>git merge ...</code> compared to <code>git log ...</code> for example). For these scenarios Clink allows you to link parsers to arguments&#39; words using Lua&#39;s concatenation operator. Parsers can also be concatenated with flags too.</p>
<pre><code class="language-lua">a_parser = clink.argmatcher():addarg({ &quot;foo&quot;, &quot;bar&quot; })
b_parser = clink.argmatcher():addarg({ &quot;abc&quot;, &quot;123&quot; })
c_parser = clink.argmatcher()
c_parser:addarg({ &quot;foobar&quot; .. a_parser }) -- Arg #1 is &quot;foobar&quot;, which has args &quot;foo&quot; or &quot;bar&quot;.
c_parser:addarg({ b_parser }) -- Arg #2 is &quot;abc&quot; or &quot;123&quot;.
</code></pre>
<p>As the example above shows, it is also possible to use a parser without concatenating it to a word. When Clink follows a link to a parser it is permanent and it will not return to the previous parser.</p>
<h4 id="functions-as-argument-options">Functions As Argument Options</h4>
<p>Argument options are not limited solely to strings. Clink also accepts functions too so more context aware argument options can be used.</p>
<pre><code class="language-lua">function rainbow_function(word)
return { &quot;red&quot;, &quot;white&quot;, &quot;blue&quot; }
end
the_parser = clink.argmatcher()
the_parser:addarg({ &quot;zippy&quot;, &quot;bungle&quot;, &quot;george&quot; })
the_parser:addarg({ rainbow_function, &quot;yellow&quot;, &quot;green&quot; })
</code></pre>
<p>The functions take a single argument which is a word from the command line being edited (or partial word if it is the one under the cursor). Functions should return a table of potential matches.</p>
<p>Some built-in matcher functions are available:</p>
<table>
<thead>
<tr>
<th align="center">Function</th>
<th>Description</th>
</tr>
</thead>
<tbody><tr>
<td align="center"><a href="#clink.dirmatches">clink.dirmatches</a></td>
<td>Generates directory matches.</td>
</tr>
<tr>
<td align="center"><a href="#clink.filematches">clink.filematches</a></td>
<td>Generates file matches.</td>
</tr>
</tbody></table>
<h4 id="shorthand">Shorthand</h4>
<p>It is also possible to omit the <code>addarg</code> and <code>addflags</code> function calls and use a more declarative shorthand form:</p>
<pre><code class="language-lua">-- Shorthand form; requires tables.
clink.argmatcher()
{ &quot;one&quot;, &quot;won&quot; } -- Arg #1
{ &quot;two&quot;, &quot;too&quot; } -- Arg #2
{ &quot;-a&quot;, &quot;-b&quot;, &quot;/?&quot;, &quot;/h&quot; } -- Flags
-- Normal form:
clink.argmatcher()
:addarg(
{ &quot;one&quot;, &quot;won&quot; } -- Arg #1
{ &quot;two&quot;, &quot;too&quot; } -- Arg #2
)
:addflags(&quot;-a&quot;, &quot;-b&quot;, &quot;/?&quot;, &quot;/h&quot;) -- Flags
</code></pre>
<p>With the shorthand form flags are implied rather than declared. When a shorthand table&#39;s first value is a string starting with <code>-</code> or <code>/</code> then the table is interpreted as flags. Note that it&#39;s still possible with shorthand form to mix flag prefixes, and even add additional flag prefixes, such as <code>{ <span class="hljs-string">'-a'</span>, <span class="hljs-string">'/b'</span>, <span class="hljs-string">'=c'</span> }</code>.</p>
<a name="filteringmatchcompletions"/>
<h4 id="filtering-match-completions">Filtering Match Completions</h4>
<p>A match generator or <code>luafunc:</code> key binding can use <a href="#clink.onfiltermatches">clink.onfiltermatches()</a> to register a function that will be called after matches are generated but before they are displayed or inserted.</p>
<p>The function receives a table argument containing the matches to be displayed, a string argument indicating the completion type, and a boolean argument indicating whether filename completion is desired. The table argument has a <code>match</code> string field and a <code>type</code> string field; these are the same as in <a href="builder:addmatch">builder:addmatch()</a>.</p>
<p>The possible completion types are:</p>
<table>
<thead>
<tr>
<th>Type</th>
<th>Description</th>
<th>Example</th>

<tbody><tr>
<td><code>&quot;?&quot;</code></td>
<td>List the possible completions.</td>

<td><code>&quot;%&quot;</code></td>
<td>Do menu completion (cycle through possible completions).</td>
<td><code>menu-complete</code> or <code>old-menu-complete</code></td>
</tr>
</tbody></table>
<p>The return value is a table with the input matches filtered as desired. The match filter function can remove matches, but cannot add matches (use a match generator instead). If only one match remains after filtering, then many commands will insert the match without displaying it. This makes it possible to spawn a process (such as <a href="https://github.com/junegunn/fzf">fzf</a>) to perform enhanced completion by interactively filtering the matches and keeping only one selected match.</p>
<pre><code class="language-lua">settings.add(&quot;fzf.height&quot;, &quot;40%&quot;, &quot;Height to use for the --height flag&quot;)

<a name="filteringthematchdisplay"/>
<h4 id="filtering-the-match-display">Filtering The Match Display</h4>
<p>In some instances it may be preferable to display potential matches in an alternative form than the generated matches passed to and used internally by Readline. For example, it might be desirable to display a <code>*</code> next to some matches, or to show additional information about each match. Filtering the match display only affects what is displayed; it doesn&#39;t affect completing matches.</p>
<p>A match generator can use <a href="#clink.ondisplaymatches">clink.ondisplaymatches()</a> to register a function that will be called before matches are displayed (this is reset every time match generation is invoked).</p>
<p>The function receives a table argument containing the matches to be displayed, and a boolean argument indicating whether they&#39;ll be displayed in a popup window. The table argument has a <code>match</code> string field and a <code>type</code> string field; these are the same as in <a href="builder:addmatch">builder:addmatch()</a>. The return value is a table with the input matches filtered as required by the match generator. The returned table can also optionally include a <code>display</code> string field and a <code>description</code> string field. When present, <code>display</code> will be displayed as the match instead of the <code>match</code> field, and <code>description</code> will be displayed next to the match. Putting the description in a separate field enables Clink to align the descriptions in a column.</p>

<p><strong>Compatibility Note:</strong> When a match display filter has been set, it changes how match generation behaves.</p>
<ul>
<li>When a match display filter is set, then match generation is also re-run whenever matches are displayed.</li>
<li>Normally match generation only happens at the start of a new word. The full set of potential matches is remembered and dynamically filtered based on further typing.</li>
<li>So if a match generator made contextual decisions during match generation (other than filtering) then it could potentially behave differently in Clink v1.x than it did in v0.x.</li>

<h2 id="coloring-the-input-text">Coloring The Input Text</h2>
<p>When the <code>clink.colorize_input</code> setting is enabled, <a href="#argumentcompletion">argmatcher</a> automatically apply colors to the input text by parsing it.</p>
<p>It&#39;s possible for an argmatcher to provide a function to override how its arguments are colored. This function is called once for each of the argmatcher&#39;s arguments.</p>
<p>It&#39;s also possible to register a classifier function for the whole input line. This function is very similar to a match generator; classifier functions are called in priority order, and a classifier can choose to stop the classification process.</p>
<h4 id="setting-a-classifier-function-in-an-argmatcher">Setting a classifier function in an argmatcher</h4>
<p>In cases where an <a href="#argumentcompletion">argmatcher</a> isn&#39;t able to color the input text in the desired manner, it&#39;s possible to supply a classifier function that overrides how the argmatcher colors the input text. An argmatcher&#39;s classifier function is called once for each word the argmatcher parses, but it can classify any words (not just the word it was called for). Each argmatcher can have its own classifier function, so when there are linked argmatchers more than one function may be invoked.</p>
<p>Words are colored by classifying the words, and each classification has an associated color. See <a href="#word_classifications:classifyword">word_classifications:classifyword()</a> for the available classification codes.</p>
<p>The <code>clink set</code> command has different syntax depending on the setting type, so the argmatcher for <code>clink</code> needs help in order to get everything right. A custom generator function parses the input text to provide appropriate matches, and a custom classifier function applies appropriate coloring.</p>
<pre><code class="language-lua">-- In this example, the argmatcher matches a directory as the first argument and
-- a file as the second argument. It uses a word classifier function to classify
-- directories (words that end with a path separator) as &quot;unexpected&quot; in the
-- second argument position.
local function classify_handler(arg_index, word, word_index, line_state, classifications)
-- `arg_index` is the argument position in the argmatcher.
-- In this example only position 2 needs special treatent.
if arg_index ~= 2 then
return
end
-- `arg_index` is the argument position in the argmatcher.
-- `word_index` is the word position in the `line_state`.
-- Ex1: in `samp dir file` for the word `dir` the argument index is 1 and
-- the word index is 2.
-- Ex2: in `samp --help dir file` for the word `dir` the argument index is
-- still 1, but the word index is 3.
-- `word` is the word the classifier function was called for and `word_index`
-- is its position in the line. Because `line_state` is also provided, the
-- function can examine any words in the input line.
if word:sub(-1) == &quot;\\&quot; then
-- The word appears to be a directory, but this example expects only

<h4 id="setting-a-classifier-function-for-the-whole-input-line">Setting a classifier function for the whole input line</h4>
<p>In some cases it may be desireable to use a custom classifier to apply coloring in an input line.</p>
<p>First create a classifier object:</p>
<pre><code class="language-lua">local my_classifier = clink.classifier(priority)
</code></pre>
<p>The <span class="arg">priority</span> argument is a number that influences when the classifier gets called, with lower numbers going before higher numbers.</p>
<p>Next define a classify function on the object, taking the following form:</p>
<pre><code class="language-lua">function my_classifier:classify(commands)
-- commands is a table of { line_state, classifications } objects, one per
-- command in the input line. For example, &quot;echo hello &amp; echo world&quot; is two
-- commands: &quot;echo hello&quot; and &quot;echo world&quot;.
end
</code></pre>
<p><span class="arg">commands</span> is a table of tables, with the following scheme:
<span class="tablescheme">{ {line_state:<a href="#line">line</a>, classifications:<a href="#word_classifications">word_classifications</a>}, ... }</span>.</p>
<p>If no further classifiers need to be called then the function should return true. Returning false or nil continues letting other classifiers get called.</p>
<pre><code class="language-lua">-- In this example, a custom classifier applies colors to command separators and
-- redirection symbols in the input line.
local cmdsep_classifier = clink.classifier(50)
function cmdsep_classifier:classify(commands)
-- The `classifications:classifyword()` method can only affect the words for

-- words within commands, it just wants to parse the whole line. And since
-- each command&#39;s `classifications:applycolor()` method can apply color
-- anywhere in the entire input line, this example can simply use the first
-- command&#39;s `classifications` object.
if commands[1] then
local line_state = commands[1].line_state
local classifications = commands[1].classifications
local line = line_state:getline()
local quote = false

<a name="customisingtheprompt"/>
<h2 id="customising-the-prompt">Customising The Prompt</h2>
<p>Before Clink displays the prompt it filters the prompt through Lua so that the prompt can be customised. This happens each and every time that the prompt is shown which allows for context sensitive customisations (such as showing the current branch of a git repository).</p>
<p>Writing a prompt filter is straightforward:</p>
<ol>
<li>Create a new prompt filter by calling <code>clink.promptfilter()</code> along with a priority id which dictates the order in which filters are called. Lower priority ids are called first.</li>
<li>Define a <code>filter()</code> function on the returned prompt filter.</li>
</ol>
<p>The filter function takes a string argument that contains the filtered prompt so far. If the filter function returns nil, it has no effect. If the filter function returns a string, that string is used as the new filtered prompt (and may be further modified by other prompt filters with higher priority ids). If the filter function returns a string and a boolean, then if the boolean is false the prompt filtering is done and no further filter functions are called.</p>
<pre><code class="language-lua">local p = clink.promptfilter(30)
function p:filter(prompt)
return &quot;new prefix &quot;..prompt..&quot; new suffix&quot; -- Add ,false to stop filtering.
end
</code></pre>
<p>The following example illustrates setting the prompt, modifying the prompt, using ANSI escape code for colors, running a git command to find the current branch, and stopping any further processing.</p>
<pre><code class="language-lua">local green = &quot;\x1b[92m&quot;
local yellow = &quot;\x1b[93m&quot;
local cyan = &quot;\x1b[36m&quot;
local normal = &quot;\x1b[m&quot;
-- A prompt filter that discards any prompt so far and sets the
-- prompt to the current working directory. An ANSI escape code
-- colors it yellow.
local cwd_prompt = clink.promptfilter(30)
function cwd_prompt:filter(prompt)
return yellow..os.getcwd()..normal
end
-- A prompt filter that inserts the date at the beginning of the
-- the prompt. An ANSI escape code colors the date green.
local date_prompt = clink.promptfilter(40)
function date_prompt:filter(prompt)
return green..os.date(&quot;%a %H:%M&quot;)..normal..&quot; &quot;..prompt
end
-- A prompt filter that may stop further prompt filtering.
-- This is a silly example, but on Wednesdays, it stops the
-- filtering, which in this example prevents git branch
-- detection and the line feed and angle bracket.
local wednesday_silliness = clink.promptfilter(45)
function wednesday_silliness:filter(prompt)
if os.date(&quot;%a&quot;) == &quot;Wed&quot; then
-- The ,false stops any further filtering.
return prompt..&quot; HAPPY HUMP DAY! &quot;, false
end
end
-- A prompt filter that appends the current git branch.
local git_branch_prompt = clink.promptfilter(50)
function git_branch_prompt:filter(prompt)
for line in io.popen(&quot;git branch 2&gt;nul&quot;):lines() do
local branch = line:match(&quot;%* (.+)$&quot;)
if branch then
return prompt..&quot; &quot;..cyan..&quot;[&quot;..branch..&quot;]&quot;..normal
end
end
end
-- A prompt filter that adds a line feed and angle bracket.
local bracket_prompt = clink.promptfilter(150)
function bracket_prompt:filter(prompt)
return prompt..&quot;\n&gt; &quot;
end
</code></pre>
<p>The resulting prompt will look like this:</p>
<pre style="border-radius:initial;border:initial"><code class="plaintext" style="background-color:black"><span style="color:#00ff00">Wed 12:54</span> <span style="color:#ffff00">c:\dir</span> <span style="color:#008080">[master]</span>
<span style="color:#cccccc">&gt;&nbsp;_</span>
</code></pre>
<p>...except on Wednesdays, when it will look like this:</p>
<pre style="border-radius:initial;border:initial"><code class="plaintext" style="background-color:black"><span style="color:#00ff00">Wed 12:54</span> <span style="color:#ffff00">c:\dir</span> <span style="color:#cccccc">HAPPY HUMP DAY!&nbsp;_</span>
</code></pre>
<p/>
<a name="escapecodes"/>
<h3 id="ansi-escape-codes-in-the-prompt-string">ANSI escape codes in the prompt string</h3>
<p>Readline needs to be told which characters in the prompt are unprintable or invisible. To help with that, Clink automatically detects most standard ANSI escape codes (and most of ConEmu&#39;s non-standard escape codes) and the BEL character (^G, audible bell) and surrounds them with <code>\001</code> (^A) and <code>\002</code> (^B) characters. For any other unprintable characters, the <code>\001</code> and <code>\002</code> characters need to be added manually. Otherwise Readline misinterprets the length of the prompt and can display the prompt and input line incorrectly in some cases (especially if the input line wraps onto a second line).</p>
<h1 id="miscellaneous">Miscellaneous</h1>
<a name="keybindings"/>
<h2 id="key-bindings">Key bindings</h2>
<p>Key bindings are defined in .inputrc files. See the <a href="#configreadline">Configuring Readline</a> section for more information.</p>
<p>Here is the quick version:</p>
<ul>
<li>A key binding is <code><em>name</em>: <em>function</em></code> or <code><em>name</em>: "<em>literal text</em>"</code>.</li>
<li>Key names are like this:<ul>
<li><code>C-a</code> and <code>&quot;\C-a&quot;</code> are both <kbd>Ctrl</kbd>+<kbd>a</kbd>.</li>
<li><code>M-a</code> and <code>&quot;\M-a&quot;</code> are both <kbd>Alt</kbd>+<kbd>a</kbd>.</li>
<li><code>M-C-a</code> and <code>&quot;\M-\C-a&quot;</code> are both <kbd>Alt</kbd>+<kbd>Ctrl</kbd>+<kbd>a</kbd>.</li>
<li><code>hello</code> is just <kbd>h</kbd>; the <code>ello</code> is a syntax error and is silently discarded by Readline.</li>
<li><code>&quot;hello&quot;</code> is the series of keys <kbd>h</kbd>,<kbd>e</kbd>,<kbd>l</kbd>,<kbd>l</kbd>,<kbd>o</kbd>.</li>
<li>Special keys like <kbd>Up</kbd> are represented by VT220 escape codes such as<code>&quot;\e[A&quot;</code> (see table below for more info).</li>
</ul>
</li>
<li>Key bindings can be either functions or macros (literal text):<ul>
<li><code>blah-blah</code> binds to a function named &quot;blah-blah&quot;.</li>
<li><code>&quot;blah-blah&quot;</code> inserts the literal text &quot;blah-blah&quot;.</li>
</ul>
</li>
</ul>
<p>You can use <code>clink info</code> to find the directories and configuration files for the current Clink session.</p>
<p>Here is an example <code>.inputrc</code> file with the key bindings that I use myself:</p>

</code></pre>
<p>The <code>clink-show-help</code> command is bound to <kbd>Alt</kbd>+<kbd>H</kbd> and lists all currently active key bindings. The list displays &quot;friendly&quot; key names, and these names are generally not suitable for use in .inputrc files. For example &quot;Up&quot; is the friendly name for <code>&quot;\e[A&quot;</code>, and &quot;A-C-F2&quot; is the friendly name for <code>&quot;\e\e[1;5Q&quot;</code>. To see key sequence strings suitable for use in .inputrc files use <code>clink echo</code> or <kbd>Alt</kbd>+<kbd>Shift</kbd>+<kbd>H</kbd>.</p>
<blockquote>
<p><strong>Note:</strong> Third party console hosts such as ConEmu may have their own key bindings that supersede Clink. They usually have documentation for how to change or disable their key bindings to allow console programs to handle the keys instead.</p>
</blockquote>
<h3 id="discovering-clink-key-sequences">Discovering Clink key sequences</h3>
<p>Clink provides an easy way to find the key sequence for any key combination that Clink supports. Run <code>clink echo</code> and then press key combinations; the associated key binding sequence is printed to the console output and can be used for a key binding in the inputrc file.</p>
<p>A chord can be formed by concatenating multiple key binding sequences. For example, <code>&quot;\C-X&quot;</code> and <code>&quot;\e[H&quot;</code> can be concatenated to form <code>&quot;\C-X\e[H&quot;</code> representing the chord <kbd>Ctrl</kbd>+<kbd>X</kbd>,<kbd>Home</kbd>.</p>
<h3 id="binding-special-keys">Binding special keys</h3>
<p>Here is a table of the key binding sequences for the special keys. Clink primarily uses VT220 emulation for keyboard input, but also uses some Xterm extended key sequences.</p>

<h3 id="lua-key-bindings">Lua Key Bindings</h3>
<p>You can bind a key to a Lua function by binding it to a macro that begins with &quot;luafunc:&quot;. Clink will invoke the named Lua function when the key binding is input. Function names can include periods (such as <code>foo.bar</code>) but cannot include any other punctuation.</p>
<p>The Lua function receives a <a href="#rl_buffer">rl_buffer</a> argument that gives it access to the input buffer.</p>
<p>Lua functions can print output, but should first call <a href="#rl_buffer:beginoutput">rl_buffer:beginoutput</a> so that the output doesn&#39;t overwrite the displayed input line.</p>
<p>Example of a Lua function key binding in a .inputrc file:</p>
<pre><code class="plaintext"><span class="hljs-string">M-C-y</span>: <span class="hljs-string">"luafunc:insert_date"</span>
<span class="hljs-string">M-C-z</span>: <span class="hljs-string">"luafunc:print_date"</span>
</code></pre>
<p>Example functions to go with that:</p>
<pre><code class="language-lua">function insert_date(rl_buffer)
rl_buffer:insert(os.date(&quot;%x %X&quot;))
end
function print_date(rl_buffer)
rl_buffer:beginoutput()
print(os.date(&quot;%A %B %d, %Y %I:%M %p&quot;))
end
</code></pre>
<h2 id="saved-command-history">Saved Command History</h2>
<p>Clink has a list of commands from the current session, and it can be saved and loaded across sessions.</p>
<p>A line won&#39;t be added to history if either of the following are true:</p>
<ul>
<li>The first word in the line matches one of the words in the <code>history.dont_add_to_history_cmds</code> setting.</li>
<li>The line begins with a space character.</li>
</ul>
<p>To prevent doskey alias expansion while still adding the line to history, you can start the line with a semicolon.</p>
<table>
<thead>
<tr>
<th>Line</th>
<th>Description</th>
</tr>
</thead>
<tbody><tr>
<td><code>somecmd</code></td>
<td>Expands doskey alias and adds to history.</td>

<td><code>&nbsp;somecmd</code></td>

<tr>

</tbody></table>
<h3 id="the-master-history-file">The master history file</h3>
<p>When the <code>history.saved</code> setting is enabled, then the command history is loaded and saved as follows (or when the setting is disabled, then it isn&#39;t saved between sessions).</p>
<p>Every time a new input line starts, Clink reloads the master history list and prunes it not to exceed the <code>history.max_lines</code> setting.</p>
<p>For performance reasons, deleting a history line marks the line as deleted without rewriting the history file. When the number of deleted lines gets too large (exceeding the max lines or 200, whichever is larger) then the history file is compacted: the file is rewritten with the deleted lines removed.</p>
<p>You can force the history file to be compacted regardless of the number of deleted lines by running <code>history compact</code>.</p>
<h3 id="shared-command-history">Shared command history</h3>
<p>When the <code>history.shared</code> setting is enabled, then all instances of Clink update the master history file and reload it every time a new input line starts. This gives the effect that all instances of Clink share the same history -- a command entered in one instance will appear in other instances&#39; history the next time they start an input line.</p>
<p>When the setting is disabled, then each instance of Clink loads the master file but doesn&#39;t append its own history back to the master file until after it exits, giving the effect that once an instance starts its history is isolated from other instances&#39; history.</p>
<h3 id="multiple-master-history-files">Multiple master history files</h3>
<p>Normally Clink saves a single saved master history list. All instances of Clink load and save the same master history list.</p>
<p>It&#39;s also possible to make one or more instances of Clink use a different saved master history list by setting the <code>%CLINK_HISTORY_LABEL%</code> environment variable. This can be up to 32 alphanumeric characters, and is appended to the master history file name. Changing the <code>%CLINK_HISTORY_LABEL%</code> environment variable takes effect at the next input line.</p>
<h1 id="sample-scripts">Sample Scripts</h1>
<p>Here are a few samples of what can be done with Clink.</p>
<h3 id="clink-completions">clink-completions</h3>
<p>The <a href="https://github.com/vladimir-kotikov/clink-completions">clink-completions</a> collection of scripts has a bunch of argument matchers and completion generators for things like git, mercurial, npm, and more.</p>
<h3 id="cmder-powerline-prompt">cmder-powerline-prompt</h3>
<p>The <a href="https://github.com/chrisant996/cmder-powerline-prompt">cmder-powerline-prompt</a> collection of scripts provides a Powerline-like prompt for Clink. It&#39;s extensible so you can add your own segments, and some configuration of built-in segments is also available.</p>
<h3 id="oh-my-posh">oh-my-posh</h3>
<p>The <a href="https://github.com/JanDeDobbeleer/oh-my-posh3">oh-my-posh</a> program can generate fancy prompts. Refer to its documentation for how to configure it.</p>
<p>Integrating oh-my-posh with Clink is easy: just save the following text to an <code>oh-my-posh.lua</code> file in your Clink scripts directory (run <code>clink info</code> to find that), and make sure the oh-my-posh.exe program is in a directory listed in the %PATH% environment variable. (Or edit the script below to provide a fully qualified path to the oh-my-posh.exe program.)</p>
<pre><code class="language-lua">-- oh-my-posh.lua
local ohmyposh_prompt = clink.promptfilter(1)
function ohmyposh_prompt:filter(prompt)
prompt = io.popen(&quot;oh-my-posh.exe&quot;):read(&quot;*a&quot;)
return prompt, false
end
</code></pre>
<h3 id="zlua">z.lua</h3>
<p>The <a href="https://github.com/skywind3000/z.lua">z.lua</a> tool is a faster way to navigate directories, and it integrates with Clink.</p>
<h1 id="troubleshooting-tips">Troubleshooting Tips</h1>
<p>If something seems to malfunction, here are some things to try that often help track down what&#39;s going wrong:</p>
<ul>
<li>Check if anti-malware software blocked Clink from injecting. Consider adding an exclusion for Clink.</li>
<li>Check <code>clink info</code>. E.g. does the state dir look right, do the script paths look right, do the inputrc files look right?</li>
<li>Check <code>clink set</code>. E.g. do the settings look right?</li>
<li>Check the <code>clink.log</code> file for clues (its location is reported by <code>clink info</code>).</li>
</ul>
<p>When <a href="https://github.com/chrisant996/clink/issues">reporting an issue</a>, please include the following which answer a bunch of commonly relevant questions and saves time:</p>
<ul>
<li>Please describe what was expected to happen.</li>
<li>Please describe what actually happened.</li>
<li>Please include the output from <code>clink info</code> and <code>clink set</code>.</li>
<li>Please include the <code>clink.log</code> file (the location is reported by <code>clink info</code>).</li>
</ul>

<h1 id="changes">Changes</h1>
<h2 id="releases-from-chrisant996clink-fork">Releases from <a href="https://github.com/chrisant996/clink">chrisant996/clink</a> fork</h2>
<h3 id="v129">v1.2.9</h3>

<li>Ignore duplicate scripts paths when loading scripts.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/118">#118</a>; inputrc is not read from state directory (regression introduced in v1.0.0).</li>
</ul>
<h3 id="v128">v1.2.8</h3>
<ul>
<li>Fixed <code>...\</code> or <code>.../</code> to change directories (path separator after several dots).</li>
<li>Fixed <code>/dirname/</code> to change directories (forward slashes when a directory is the only thing in the input line).</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/114">#114</a>; &quot;Clink already loaded in process&quot; error when autorun is installed for both Current User and All Users.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/113">#113</a>; forward slash translation didn&#39;t work with the <code>cd</code> command.</li>
</ul>
<h3 id="v127">v1.2.7</h3>
<ul>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/113">#113</a>; <code>clink.slash_translation()</code> had been removed (regression introduced in v1.0.0).<ul>
<li>The new <code>match.translate_slashes</code> setting controls the default behavior for slash translation for completion matches.</li>
<li>The new <code>clink.translateslashes()</code> API can override slash translation for completion matches (and <code>clink.slash_translation()</code> is supported for backward compatibility).</li>
</ul>
</li>
</ul>
<h3 id="v126">v1.2.6</h3>
<ul>
<li>Fixed tilde expansion for directory by itself; now <code>~\</code> can change the working directory to the <code>~</code> directory.</li>
<li>Fixed pagination when displaying completions that take more than 1 line to display.</li>
<li>Fixed inserting directory match completions when a Lua script didn&#39;t include a trailing path separator in the directory match.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/111">#111</a>; <code>..</code> completion is different from bash (regression introduced in v1.0.0).</li>
</ul>
<h3 id="v125">v1.2.5</h3>
<ul>
<li>Added <code>os.expandenv()</code> function to expand environment variables in a string.</li>
<li>Added <code>console.cellcount()</code> function to count the cells a string will use when displayed.</li>
<li>Added <code>console.plaintext()</code> function to remove ANSI escape codes from a string.</li>
<li>Clink now sets <code>%=clink.bin%</code> that points to the Clink binaries directory. This can be particularly useful for a portable installation of Clink so that scripts can find the Clink binaries directory and construct relative paths to other nearby files.</li>
<li>Clean up column alignment in <code>--help</code> texts.</li>
<li>Fixed <code>history.sticky_search</code> with anchored history search.</li>
<li>Fixed <code>clink inject --profile</code> to use correct log file name while initially injecting.</li>
<li>Fixed Clink autorun to be more compatible with Cmder (<a href="https://github.com/cmderdev/cmder/issues/2536">Cmder #2536</a>).</li>
</ul>
<h3 id="v124">v1.2.4</h3>
<ul>
<li>Added support for <kbd>Shift</kbd>+<kbd>Arrows</kbd> to select text and typing to replace selected text.</li>
<li>Added optional argument to <code>word_classifications:classifyword()</code> and <code>word_classifications:applycolor()</code> to allow only applying color where another color hasn&#39;t yet been applied.</li>
<li>Fixed first <kbd>Up</kbd> after reusing a history line so that it gets the reused history line, rather than getting the previous history line.</li>
<li>Fixed <code>add-history</code> command to not add blank lines to history.</li>
<li>Fixed <code>rl.setmatches()</code> (regression introduced in v1.1.26).</li>
<li>Fixed input coloring for <code>clink set</code> and any color setting name (regression introduced in v1.2).</li>
<li>Fixed potential crash with <code>clink history --session</code>.</li>
<li>Fixed <kbd>Ctrl</kbd>+<kbd>D</kbd> when <code>cmd.ctrld_exits</code> is disabled; it didn&#39;t exit, but it did still discard the input line and start a new prompt.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/107">#107</a>; autorun reports inject failures (regression introduced in v1.2.3).</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/106">#106</a>; history missing <code>--bare</code> option (regression introduced in v1.2.3).</li>
</ul>
<h3 id="v123">v1.2.3</h3>
<ul>
<li>Added <code>history.sticky_search</code> setting: when enabled, reusing a history line does not add the reused line to the end of the history, and it leaves the history search position on the reused line so next/prev history can continue from there (e.g. replaying commands via <kbd>Up</kbd> several times then <kbd>Enter</kbd>, <kbd>Down</kbd>, <kbd>Enter</kbd>, etc).</li>
<li>Added failure reporting and logging when <code>clink inject</code> fails.</li>
<li>Added <code>--unique</code> flag for use with <code>clink history compact --unique</code> to remove duplicate entries from the history list.</li>
<li>The <code>clink-popup-complete</code> command now matches wildcards.</li>
<li>Restored the <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>U</kbd> key binding from v0.4.9 (moves the current working directory up one level).</li>
<li>Fixed searching for inputrc files to also search in the profile directory (regression introduced in v1.0.0).</li>
<li>Fixed incremental search in the History popup list to search in reverse order (bottom to top).</li>
<li>Fixed <code>clink-popup-history</code> to set the history search position like other history search commands do, so that it plays well with the <code>history.sticky_search</code> setting.</li>
</ul>
<h3 id="v122">v1.2.2</h3>
<ul>
<li>Added <code>%CLINK_HISTORY_LABEL%</code> environment variable to use a different master history file (fixes <a href="https://github.com/chrisant996/clink/issues/99">#99</a>).</li>
</ul>
<h3 id="v121">v1.2.1</h3>
<ul>
<li>Added Troubleshooting Tips section in the documentation.</li>
<li>Added backward compatibility for <code>clink set</code> with v0.4.9. Old setting names and values are not documented, but are automatically mapped to the appropriate new setting(s). This was done so that suggestions in old web sites and posts can usually continue to work, to reduce confusion and support burden.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/97">#97</a>; VS2017 error C2039: &#39;min&#39;: is not a member of &#39;std&#39;.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/96">#96</a>; wrong setting string (the name of a setting was accidentally truncated).</li>
<li>Fixed some slightly inaccurate/incomplete migration from old settings to new settings.</li>
</ul>
<h3 id="v12">v1.2</h3>
<ul>
<li>First official release from <a href="https://github.com/chrisant996/clink">chrisant996/clink</a> fork.</li>
</ul>
<h3 id="v1149">v1.1.49</h3>
<ul>
<li>Added <code>clink.classifier()</code> to enable coloring the input line independently from argmatchers.</li>
<li>Added <code>word_classifications:applycolor()</code> to apply SGR escape codes anywhere in the input line.</li>
<li>Removed <code>word_classifications:iswordclassified()</code>.</li>
<li>Fixed the Product Version string in the binary file version resources.</li>
</ul>
<h3 id="v1148">v1.1.48</h3>
<ul>
<li>Added <code>clink.getansihost()</code> function to get Clink&#39;s best guess who will process ANSI escape codes (can be useful for avoiding 256 bit and 24 bit color codes, for example).</li>
<li>Added detection for being hosted in ConsoleZ.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/20">#20</a>; <code>set /p VAR=&quot;&quot;</code> shows the normal command prompt text instead of empty prompt text.</li>
</ul>
<h3 id="v1147">v1.1.47</h3>
<ul>
<li>Added default key binding for <kbd>Ctrl</kbd>+<kbd>Space</kbd> to invoke <code>old-menu-complete</code>, which is the most similar to CMD&#39;s standard <kbd>Tab</kbd> behavior.</li>
<li>Fixed <code>search-ignore-case</code> config variable to be on by default.</li>
</ul>
<h3 id="v1146">v1.1.46</h3>
<ul>
<li>Added <code>rl.setvariable()</code> to temporarily override the value of a Readline config variable.</li>
<li>The completion commands now also expand tilde by itself (<code>~</code>), in addition to tilde followed by a path separator (<code>~\etc</code>).</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/94">#94</a>; setting <code>history.save</code> to False also disables interactive history in subsequent sessions.</li>
</ul>
<h3 id="v1145">v1.1.45</h3>
<ul>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/93">#93</a>; stdout is sometimes broken by Cmder init.bat.</li>
</ul>
<h3 id="v1144">v1.1.44</h3>
<ul>
<li>Added <code>clink.getsession()</code>.</li>
<li>Added <code>%CLINK_NOAUTORUN%</code> which overrides automatic inject when Clink is installed for autorun.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/92">#92</a>; <code>clink-popup-history</code> and similar commands not working with ConEmu and Cmder (regression introduced in v1.1.25).</li>
</ul>
<h3 id="v1143">v1.1.43</h3>
<ul>
<li>Added <code>clink history --diag</code> flag that prints diagnostic information while performing history operations.</li>
<li>Minor optimization in <code>clink history</code> when printing the full list of history items.</li>
<li>Fixed <code>clink history compact</code> so it actually performs compaction.</li>
</ul>
<h3 id="v1142">v1.1.42</h3>
<ul>
<li>Added <code>clink history --bare</code> flag to omit history item numbers.</li>
<li>Added several Lua functions:<ul>
<li><code>io.popenrw()</code> is like <code>io.popen()</code>, but returns both a read file handle and a write file handle (see documentation for important usage warning).</li>
<li><code>os.createtmpfile()</code> creates a unique named temporary file, with control over the prefix and suffix and path.</li>
<li><code>os.getfullpathname()</code> to get the full path name for a file.</li>
<li><code>os.getlongpathname()</code> to get the long path name for a file.</li>
<li><code>os.getshortpathname()</code> to get the 8.3 short path name (if available) for a file.</li>
</ul>
</li>
<li>Improved argument validation for Clink&#39;s Lua APIs. This could expose bugs in existing scripts, so there is also a <code>lua.strict</code> setting that can be disabled to revert back to loose argument validation.</li>
<li>Updated documentation.</li>
<li>Fixed <code>clink history compact</code> so that it forces compaction as intended.</li>
<li>Fixed completion for <code>clink set</code> so that filename completion works in string settings.</li>
<li>Fixed backwards return value from <code>rl.invokecommand()</code>.</li>
<li>Fixed console input/output modes across <code>luafunc:</code> key bindings, in case the Lua functions spawn a process that alters the console mode without restoring it.</li>
</ul>
<h3 id="v1141">v1.1.41</h3>
<ul>
<li>Added <code>terminal.adjust_cursor_style</code> setting as a workaround to avoid interfering with the Windows 10 Cursor Shape console setting. There are several trade-offs, though.</li>
<li>Added <code>rl_buffer:refreshline()</code> function to redraw the input line, e.g. in case something has written over it.</li>
<li>Added <code>os.getpid()</code> function to get the process ID, intended mainly to help salt unique resource names.</li>
<li>Added <code>clink.onfiltermatches()</code> so scripts can register a callback function to run after Clink generates matches and before it displays them.</li>
</ul>
<h3 id="v1140">v1.1.40</h3>
<ul>
<li>Added a group of <code>clink-complete-numbers</code> commands that do completion for numbers from the console screen, bound to <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>N</kbd> by default.</li>
<li>Added <code>rl.getlastcommand()</code> function that returns the name of the last command invoked by key bindings.</li>
<li>Fixed sort order in <kbd>Alt</kbd>+<kbd>H</kbd> for the newly supported key bindings (that were added in v1.1.39).</li>
<li>Fixed <kbd>Ctrl</kbd>+<kbd>Space</kbd> (regression introduced in v1.1.39).</li>
<li>Fixed various <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>whatever</kbd> combinations (regression introduced in v1.1.39).</li>
<li>Fixed <code>rl.setmatches()</code> when the input line is not empty and <code>clink.colorize_input</code> is enabled.</li>
</ul>
<h3 id="v1139">v1.1.39</h3>
<ul>
<li>Added support for many more key bindings, such as <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+Letter keys.</li>
<li>Added <code>terminal.differentiate_keys</code> setting that when enabled allows binding <kbd>Ctrl</kbd> + <kbd>H</kbd> or <kbd>I</kbd> or <kbd>M</kbd> or <kbd>[</kbd> separately from <kbd>Backspace</kbd>, <kbd>Tab</kbd>, <kbd>Return</kbd>, or <kbd>Escape</kbd>.</li>
<li>Removed <code>terminal.modify_other_keys</code> setting and made it always enabled.</li>
<li>Changed <code>terminal.use_altgr_substitute</code> to be disabled by default so that <kbd>Ctrl</kbd>+<kbd>Alt</kbd> key bindings can work by default on keyboards with <kbd>AltGr</kbd>.</li>
<li>Changed output from <code>clink echo</code> so it&#39;s directly usable in the inputrc files.</li>
<li>Fixed <code>terminal.use_altgr_substitute</code> to only affect <kbd>AltGr</kbd> substitute key combinations (it had always broken the <kbd>RightAlt</kbd> key in general on other keyboard layouts).</li>
<li>Fixed a benign issue with the console input mode in <code>clink echo</code>.</li>
</ul>
<h3 id="v1138">v1.1.38</h3>
<ul>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/84">#84</a>; added <code>terminal.use_altgr_substitute</code> setting.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/80">#80</a>; clink.log is not deleted when Cmder injects Clink.</li>
</ul>
<h3 id="v1137">v1.1.37</h3>
<ul>
<li>Fixed copy to clipboard (it never cleared the clipboard!).</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/82">#82</a>; added two new <code>clink.paste_crlf</code> modes: <code>ampersand</code> replaces newlines with ampersands, and <code>crlf</code> pastes newlines as-is and executes any commands ending in a newline.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/69">#69</a>; space in the prompt disappears after enter echo: added support for CJK codepages.</li>
</ul>
<h3 id="v1136">v1.1.36</h3>
<ul>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/79">#79</a>; Issue with United States - international keyboard layout (regression introduced in v1.1.0).</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/78">#78</a>; crash when history file contains a line longer than 8192 characters (regression introduced in v1.1.2-alpha).</li>
</ul>
<h3 id="v1135">v1.1.35</h3>
<ul>
<li>Fixed when the <code>mark-directories</code> inputrc variable is <code>off</code> (regression introduced in v1.1.1-alpha).</li>
<li>Fixed Lua reading from stdin, especially in the Lua debugger (regression introduced in v1.1.25).</li>
<li>Fixed exponential cost performance bug in Readline when removing duplicate matches.</li>
</ul>
<h3 id="v1134">v1.1.34</h3>
<ul>
<li>Fixed copying to clipboard (CF_UNICODETEXT was put on the clipboard correctly, but CF_TEXT was empty and should have been omitted to let Windows automatically convert it from the Unicode text).</li>
</ul>
<h3 id="v1133">v1.1.33</h3>
<ul>
<li>Make the &quot;replacing arglink&quot; warning message a little more informative, and write a lua traceback to the Clink log file.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/77">#77</a>; with ConsoleZ scrolling does not always work.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/76">#76</a>; cannot <code>cd</code> up multiple directories normally.</li>
</ul>
<h3 id="v1132">v1.1.32</h3>
<ul>
<li>Added support for non-standard escape codes to set the window title or print environment variables. Depending on the <code>terminal.emulation</code> setting, the behavior is slightly different. When <code>emulate</code> Clink processes the escape codes. When <code>native</code> with ConEmu (and Clink) the escape codes are passed to ConEmu, except that Clink processes the environment variable codes in prompt strings. When <code>native</code> with other terminals, Clink preprocesses the title and environment variable escape codes in prompt strings, but passes the escape codes to the terminal outside of prompt strings.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/67">#67</a>; AutoRun interferes with Cmder.</li>
</ul>
<h3 id="v1131">v1.1.31</h3>
<ul>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/74">#74</a>; clink gets confused by non-standard ConEmu escape codes.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/73">#73</a>; <code>exec.space_prefix</code> and other settings defined in Lua scripts don&#39;t take effect until second input line (regression introduced in v1.1.4).</li>
</ul>
<h3 id="v1130">v1.1.30</h3>
<ul>
<li>Fixed history compacting on x86 (regression introduced in v1.1.2-alpha).</li>
</ul>
<h3 id="v1129">v1.1.29</h3>
<ul>
<li>Added <code>clink installscripts</code> and <code>clink uninstallscripts</code> to make it easy for package managers like Scoop to install/uninstall script packages for use with Clink. The installed script paths are stored in the registry for the current user.</li>
<li>Fixed <code>bold</code> vs <code>bright</code> colors to more accurately follow generally accepted ANSI escape code conventions:<ul>
<li>Renamed <code>dim</code> to <code>nobold</code> for clarity (though <code>dim</code> is still recognized for backward compatibility).</li>
<li><code>bold</code> adds intensity to a non-intense color (e.g. <code>cyan</code> which is 36).</li>
<li><code>nobold</code> removes intensity added by <code>bold</code> (e.g. <code>1;36</code> becomes <code>36</code>), but does not remove intensity from an explicit intense color (such as <code>bright cyan</code> which is <code>96</code>).</li>
</ul>
</li>
<li>Fixed support for <code>--file=</code> flags in argmatchers.</li>
<li>Fixed match display filtering on the first try for a word (regression introduced in v1.1.19).</li>
<li>Fixed the <code>clink --profile</code> flag (regression introduced in v1.1.10).</li>
<li>Fixed <code>clink info</code> to accurately report the script dirs (it didn&#39;t account for the <code>clink.path</code> setting correctly).</li>
</ul>
<h3 id="v1128">v1.1.28</h3>
<ul>
<li>Renamed the <code>log.rl_terminal</code> setting to <code>debug.log_terminal</code>; it has already been repeatedly very useful in multiple was since it was added, so it stays.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/70">#70</a>; ctrl+c not working (regression introduced in v1.1.25).</li>
</ul>
<h3 id="v1127">v1.1.27</h3>
<ul>
<li>Added <code>color.argmatcher</code> setting which, when set, is used to color a command name if it has an associated argmatcher (this supersedes <code>color.cmd</code>, <code>color.doskey</code>, and <code>color.input</code>). By default it&#39;s not set.</li>
<li>Added <code>log.rl_terminal</code> setting which logs all terminal input and output for Readline (this setting may be renamed or removed in the future).</li>
</ul>
<h3 id="v1126">v1.1.26</h3>
<ul>
<li>Added <code>rl.invokecommand()</code> which can invoke a Readline command from inside a &quot;luafunc:&quot; key binding.</li>
<li>Added <code>rl.setmatches()</code> which can override match completions from inside a &quot;luafunc:&quot; key binding.</li>
<li>Worked around UTF8 key binding problem with Readline which had been causing some meta key bindings (M-x, M-C-x, etc) to sometimes produce garbled key bindings and garbled entries in <code>clink-show-help</code> (<kbd>Alt</kbd>+<kbd>H</kbd>).</li>
<li>Fixed crash if &quot;luafunc:&quot; key binding macro refers to a symbol that doesn&#39;t exist.</li>
</ul>
<h3 id="v1125">v1.1.25</h3>
<ul>
<li>Added <code>clink-find-conhost</code> command that, when in a default (conhost) console window, is equivalent to picking &quot;Find...&quot; from the system menu.</li>
<li>Added <code>clink-mark-conhost</code> command that, when in a default (conhost) console window, is equivalent to picking &quot;Mark&quot; from the system menu.</li>
<li><code>clink-copy-word</code> now copies the current word by default, but copies the nth word if a numeric argument is entered (see &quot;Readline Arguments&quot; in the Readline manual).</li>
<li>Fixed match display filtering to not exceed the screen width (regression introduced in v1.1.12).</li>
<li>Fixed multi-key sequences; in some cases it could get confused about whether an input key is part of a multi-key binding sequence (regression introduced in v1.1.1-alpha).</li>
<li>Fixed stray input processing by conhost (holding <kbd>Ctrl</kbd>+<kbd>A</kbd> or <kbd>Ctrl</kbd>+<kbd>F</kbd> or etc could accidentally trigger conhost&#39;s shortcut keys).</li>
<li>Fixed popup window location and size when using Windows Terminal.</li>
<li>Fixed input coloring after <code>operate-and-get-next</code>; also fixes brief flicker of incorrect coloring whenever the input line is modified.</li>
</ul>
<h3 id="v1124">v1.1.24</h3>
<ul>
<li><code>auto</code> for <code>terminal.emulation</code> now uses native VT support on Windows 10 build 15063 and higher, unless the HKCU\Console\ForceV2 regkey is 0.</li>
<li>Special quote handling now enables <code>&quot;dir\&quot;fi</code> to complete to <code>&quot;dir\file&quot;</code>. CMD simply strips quotes during completion, and now Clink behaves similarly.</li>
<li><strong>Breaking Change:</strong> <code>line:getword()</code> and <code>line:getendword()</code> now strip quotes from the word. This should generally automagically make existing match generators work even with embedded quotes, but there&#39;s a chance that some match generator might need to be updated. This seems like a reasonable compromise, given the general benefit purchased by this breaking change.</li>
<li><code>os:globdirs()</code> and <code>os:globfile()</code> strip quotes from the <span class="arg">globpattern</span> in order to behave more like CMD. Embedded quotes are nonsensical and the intended interpretation is clear, so the APIs now help out with that.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/66">#66</a>; crash when injecting into 32 bit cmd (regression introduced in v1.1.21).</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/64">#64</a>; wrong cursor position when PROMPT contains BEL character.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/62">#62</a>; argmatchers should color <code>-x:&quot;foo&quot;</code> as a flag if <code>-x:</code> is a flag.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/61">#61</a>; argmatchers should not handle completion for text immediately following <code>-flag:</code>. Instead it always uses file completion. A custom generator can be used to override that behavior.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/60">#60</a>; completion fails with multiple slashes.</li>
<li>Fixed completion in some circumstances. Readline and Clink didn&#39;t always agree on where the word breaks were; now Clink always tells Readline where the word breaks are (so that completion, input colorization, and lua scripts can all work properly and consistently).</li>
<li>Fixed 256 color ANSI codes.</li>
</ul>
<h3 id="v1123">v1.1.23</h3>
<ul>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/57">#57</a>; slashes not normalized in some cases.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/45">#45</a>; interaction between <code>history.dupe_mode</code>=<code>erase_prev</code> and <code>history.shared</code>=<code>false</code>.</li>
<li>Fixed <code>menu-complete-wraparound</code> when off and there&#39;s only 1 match.</li>
</ul>
<h3 id="v1122">v1.1.22</h3>
<ul>
<li>Added <code>menu-complete-wraparound</code> (on by default) that controls whether completion commands wrap around when cycling past an end (affects popup windows as well).</li>
<li>Fixed match completion getting stuck (regression introduced in v1.1.19).</li>
<li>Fixed active mark region so it gets deactivated appropriately (it wasn&#39;t hooked up fully for Readline&#39;s callback mode, which is the mode Clink uses).</li>
<li>Fixed <code>clink-show-help</code> (<kbd>Alt</kbd>+<kbd>H</kbd>) so it&#39;s able to list <code>C-@</code> bindings.</li>
<li>Fixed inconsistent mark color.</li>
</ul>
<h3 id="v1121">v1.1.21</h3>
<ul>
<li>Added <code>clink.oninject()</code> so scripts can register a callback function to run when Clink is injected into CMD.</li>
<li>Added <code>console.linehascolor()</code> function that returns whether the specified line contains any of the specified colors.</li>
<li>Added <code>console.findprevline()</code> and <code>console.findnextline()</code> functions that can search backwards or forwards for text and/or colors in the screen buffer. Regular expressions may be used.</li>
<li>Fixed doskey alias parsing for match generators and input line coloring (Clink had been using slightly different parsing rules than CMD does).</li>
<li>Fixed the &quot;-- More --&quot; prompt while listing key bindings; <kbd>Esc</kbd> didn&#39;t quit, and unexpected keys weren&#39;t ignored.</li>
</ul>
<h3 id="v1120">v1.1.20</h3>
<ul>
<li>Now you can bind Lua functions to keys via &quot;luafunc:&quot; macros! Added new <code>rl_buffer</code> type that gets passed to the Lua function.</li>
<li>Added a group of <code>console</code> Lua APIs intended mainly for use by Lua function key bindings (e.g. <code>console.scroll()</code>).</li>
<li>Added <code>string.equalsi()</code> function that performs a case insensitive UTF8 comparison of two strings.</li>
<li>Added <code>string.matchlen()</code> function that compares two UTF8 strings and returns how many characters match at the beginning, or -1 if the entire strings match. It respects the <code>match.ignore_case</code> and <code>match.ignore_accents</code> settings.</li>
<li>Added <code>path.toparent()</code> function that adjust the input string by moving up one directory level.</li>
<li>Added <code>clink.onendedit()</code> so scripts can register a callback function to run when editing finishes (e.g. <kbd>Enter</kbd> is pressed). If desired, the function can even change the input text. This is very powerful, and should be used carefully.</li>
<li>Changed <code>os.getbatterystatus()</code> to return a table with the battery status details, rather than four separate return values.</li>
<li>Fixed the <code>doskey.enhanced</code> setting to not expand doskey aliases when preceded by a space. However, a doskey alias after a <code>&amp;</code> or <code>|</code> command separator needs to be preceded by two spaces to avoid expanding it. That&#39;s so <code>alias &amp; alias</code> expands both, and <code> alias &amp; alias</code> expands neither; while the rules are more complicated to explain, they make more sense visually.</li>
<li>Fixed environment variable completion (regression introduced in v1.1.19).</li>
<li>Fixed Cmder startup (regression introduced in v1.1.17). Cmder expects to be able to replace Clink v0.4.9&#39;s clink.lua file, but there is no such thing anymore in newer versions of Clink. To be properly backwardly compatible with Clink v0.4.9 requires loading clink.lua (if it exists) from the first script directory listed by <code>clink info</code>, and ignoring clink.lua files in all other script directories.</li>
</ul>
<h3 id="v1119">v1.1.19</h3>
<ul>
<li>Improved responsiveness while typing: matches are collected only on demand, instead of always while typing. This makes it possible to always support match completion for UNC paths.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/50">#50</a>; <kbd>Alt</kbd>+<kbd>H</kbd> could warn about likely mistakes in key bindings.</li>
</ul>
<h3 id="v1118">v1.1.18</h3>
<ul>
<li>The input text now has context sensitive coloring based on the argmatchers. It&#39;s on by default and can be turned off with <code>clink set clink.colorize_input false</code>.</li>
<li>Updated the Readline library to 8.1.</li>
<li>Terminal emulation now supports the audible bell character.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/48">#48</a>; <code>menu-complete</code> gets stuck.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/47">#47</a>; <kbd>Alt</kbd>+<kbd>D</kbd> erases history instead of word.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/46">#46</a>; typing <code>..</code> in subdirectory of root doesn&#39;t work.</li>
<li>Fixed restoring color after pager when showing help.</li>
<li>Fixed <code>clink set</code> match completions for color settings.</li>
</ul>
<h3 id="v1117">v1.1.17</h3>
<ul>
<li>Added <code>os.getbatterystatus()</code> function that gets battery status information much faster than launching <code>wmic</code>.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/44">#44</a>; Path completion doesn&#39;t work with <code>cd /d</code>.</li>
<li>Fixed loading scripts to ignore loading clink.lua, so that loading scripts behaves like Clink v0.4.9.</li>
</ul>
<h3 id="v1116">v1.1.16</h3>
<ul>
<li>Added <code>match.ignore_accent</code> setting (enabled by default) that ignores Latin alphabet diacriticals when completing matches (e.g. <code>ä</code> matches <code>a</code>, <code>ı</code> matches <code>i</code>, <code>ł</code> matches <code>l</code>, etc).</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/42">#42</a>; history lines are split on special characters.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/41">#41</a>; Enable custom doskey handling of <code>..</code> and <code>-</code>.</li>
<li>Fixed Readline bug inserting dir matches; <code>\win_ foo</code> (cursor at <code>_</code>) would become <code>\Windows\\_ foo</code>.</li>
<li>Fixed the <code>quoted-insert</code> command to insert just <code>\x1b</code> when <kbd>ESC</kbd> is pressed.</li>
</ul>
<h3 id="v1115">v1.1.15</h3>
<ul>
<li>Migrating settings now immediately writes a new settings file, instead of waiting until a setting is changed.</li>
<li>Added support to detect when running in Windows Terminal and use native terminal support (which enables things like Xterm 256 and 24-bit color support).</li>
<li>Added terminal emulation support for Xterm 256 and 24-bit color escape codes. Clink maps the specified color to the most similar color in the active 16 color palette (using the CIELAB color space). To get full support for 24-bit color, it&#39;s necessary to use ConEmu or Windows Terminal or a similar console host, or to set <code>terminal.emulation</code> to <code>native</code> (which isn&#39;t supported on some older Windows OS versions).</li>
<li>Allow doskey macros named <code>..</code> or <code>-</code>, and also now doskey macros that resolve to <code>..</code> or <code>-</code> or a directory name will work (just like if the macro text had been typed at the Clink prompt).</li>
<li>Fixed compatibility problem with various scripts getting the %HOME% environment variable. Now if it isn&#39;t set, then Clink synthesizes %HOME% from %HOMEDRIVE% and %HOMEPATH% or from %USERPROFILE%.</li>
<li>Fixed saving color settings to behave like other settings: only write a setting&#39;s value to the setting file if it differs from the default value.</li>
<li>Fixed the <code>clink.print()</code> Lua function so it also works during loading scripts and during prompt filtering.</li>
<li>Fixed the Readline input text display getting garbled if the filtered prompt includes Xterm&#39;s OSC window title code (<code>\x1b]0;text\x07</code>). Clink doesn&#39;t support that escape code, but at no longer garbles the input text if that escape code is present.</li>
</ul>
<h3 id="v1114">v1.1.14</h3>
<ul>
<li>Migrate settings and history from an old version of Clink, if present. This only happens if the new-version Clink settings or history files don&#39;t exist. (Deleting an existing new-version Clink settings or history file will cause migration to happen again.)</li>
<li>Added <code>color.prompt</code> setting for backward compatibility with Clink v0.4.x.</li>
</ul>
<h3 id="v1113">v1.1.13</h3>
<ul>
<li>Fixed <code>clink.arg.register_parser</code> backward compatibility.</li>
</ul>
<h3 id="v1112">v1.1.12</h3>
<ul>
<li>Added <code>clink.ondisplaymatches()</code> as a replacement for the deprecated <code>clink.match_display_filter</code>. The new API is able to support popup list windows as well.</li>
<li>Speculative possible fix for <a href="https://github.com/chrisant996/clink/issues/35">#35</a> Crash when clink on clink.bat.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/33">#33</a>; Tab autocomplete, auto-quoting paths doesn&#39;t seem to work as in Clink 0.4.9.</li>
</ul>
<h3 id="v1111">v1.1.11</h3>
<ul>
<li>Changed to load Lua scripts only once per session, unless forced to reload them. This enables backward compatibility for things like <a href="https://github.com/skywind3000/z.lua">z.lua</a> which has certain features that rely on Clink only loading scripts once per session.</li>
<li>Added <code>clink.onbeginedit()</code> so scripts can register a callback function to run each time the edit prompt is activated.</li>
<li>Added <code>lua.reload_scripts</code> setting to optionally force reloading Lua scripts each time the edit prompt is activated.</li>
<li>Added <code>color.message</code> setting for the Readline message area color (e.g. the search prompt message or digit argument prompt message, etc).</li>
<li>Fixed stray sticky <code>=</code> appended to completions after typing <code>set </code> and then typing a different command.</li>
</ul>
<h3 id="v1110">v1.1.10</h3>
<ul>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/32">#32</a>; hooking <code>ReadConsoleW</code> on Windows 7.</li>
</ul>
<h3 id="v119">v1.1.9</h3>
<ul>
<li>Added backward compatibility for <code>clink.match_display_filter</code>. The clink-completions/git.lua script uses it a lot, and that should all be working now.</li>
<li><code>settings.add</code> adds a color setting when the type is string and the name starts with &quot;color.&quot;.</li>
<li><code>settings.get</code> now has an extra parameter to request the user friendly color name when getting a color setting.</li>
<li>Added <code>clink.version_encoded</code> variable with the Clink version number as <em>MMmmmpppp</em> (e.g. v1.1.9 is <code>10010009</code>) to make it easy for scripts to check for feature availability.</li>
<li>The <code>clink info</code> command now shows Lua script paths as well.</li>
<li>Fixed backward compatibility for loading scripts from the profile directory (if <code>clink.path</code> isn&#39;t set, then load scripts from the DLL directory and the profile directory).</li>
<li>Fixed some <code>color.input</code> bleed through to other things (introduced in v1.1.5).</li>
<li>Fixed scroll commands (regression introduced by input line color in v1.1.5).</li>
<li>Fixed horizontally sorted match display and re-enabled the performance fix from v1.1.4.</li>
<li>Fixed wildcard evaluation with non-file and non-directory matches (e.g. a branch name <code>origin/master</code> accidentally didn&#39;t match <code>or</code> or <code>*ma</code> because of the <code>/</code>).</li>
<li>Fixed sort order of <code>foo\</code> vs <code>foo.bar\</code> when displaying matches or using the <code>menu-complete</code> family of commands.</li>
<li>Fixed potentially-missing trailing path separator when <code>menu-complete</code> completes a directory match (regression introduced by wildcard matching in v1.1.5).</li>
<li>Other obscure minor fixes.</li>
</ul>
<h3 id="v118">v1.1.8</h3>
<ul>
<li>Fixed file match completions when an argmatcher only generates flag matches.</li>
<li>Fixed automatic inferring whether Readline should use filename completion and/or display rules (regression introduced by backward compatibility in v1.1.3-alpha).</li>
<li>Fixed backward compatibility for <code>clink.find_files()</code> and <code>clink.find_dirs()</code> (regression introduced by performance improvement in v1.1.7).<ul>
<li>Ignore extra arguments after the first one (the performance improvement in v1.1.7 revealed that some scripts call <code>clink.find_files()</code> with extra invalid arguments; e.g. clink-completions/modules/matchers.lua).</li>
<li>Don&#39;t append a trailing path separator on directory names returned by these functions (the new <code>os.globfiles()</code> and <code>os.globdirs()</code> functions do, but the old <code>clink.find_files()</code> and <code>clink.find_dirs()</code> functions should not).</li>
</ul>
</li>
<li>Fixed backward compatibility for coloring matches (regression introduced by backward compatibility changes in v1.1.4).</li>
</ul>
<h3 id="v117">v1.1.7</h3>
<ul>
<li>Performance improvement when displaying matches: When enumerating files and dirs, the <code>os.globfiles</code> and <code>os.globdirs</code> functions have all the info about each file. Now they can return that info in a table. This frees the match display function from needing to do any further file system IO. The performance boost is noticeable.</li>
<li>Rewrote the color settings: the .fg and .bg sub-settings are gone, and the main setting now uses a more natural syntax (e.g. <code>clink set color.input bright yellow</code> or <code>clink set color.modmark bright cyan on blue</code>).</li>
<li>Added &quot;cmd&quot; match type for shell (CMD.EXE) command completions.</li>
<li>Added VT emulation for the reverse video SGR parameters.</li>
<li>Fixed tab completion for <code>clink set <em>setting</em></code>, and also handle the new color setting syntax.</li>
<li>Fixed confusing behavior if multiple scripts try to add settings with the same name (now the first one succeeds and the rest report errors).</li>
</ul>
<h3 id="v116">v1.1.6</h3>
<ul>
<li>Hooked up tilde completion in the <code>cd</code>, <code>md</code>, and <code>rd</code> command argmatchers.</li>
<li>Hooked up tilde completion with the <code>exec.enable</code> setting (&quot;~\pro&quot; matches &quot;C:\Users\myusername\program.exe&quot;).</li>
<li>When <code>terminal.emulation</code> is <code>auto</code>, now it also detects ANSI{32|64}.DLL just like Clink 0.4.8 did.</li>
</ul>
<h3 id="v115">v1.1.5</h3>
<ul>
<li>The <code>menu-complete</code> family of commands now support matching <code>?</code> and <code>*</code> wildcards when the <code>match.wild</code> setting is enabled.</li>
<li>Added <code>colour.input</code> and <code>colour.modmark</code> settings for coloring Readline&#39;s input line.</li>
<li>Added <code>clink.upper()</code> Lua function, and both <code>clink.lower()</code> and <code>clink.upper()</code> are properly UTF8 aware now.</li>
<li>Added <code>clink-copy-word</code> command that copies the word at the cursor to the clipboard.</li>
<li>Added <code>clink.promptfilter</code> setting to control whether to filter the prompt with Lua scripts.</li>
<li>Renamed <code>terminal.emulate</code> setting to <code>terminal.emulation</code>.</li>
<li>Improved executable file extension logic to consistently use %PATHEXT% (and efficiently).</li>
<li>Improved file extension logic (e.g. &quot;file.foo bar&quot; has no extension because of the space).</li>
<li>Updated arg matcher for <code>clink</code> itself (was missing some flags).</li>
<li>Changed <code>colour.hidden</code> setting to not be set by default.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/28">#28</a>; Tab completion for &quot;~&quot; does not work.</li>
<li>Fixed <a href="https://github.com/chrisant996/clink/issues/25">#25</a>; Unicode surrogate pairs (and emoji) input isn&#39;t working -- Microsoft Terminal renders the text correctly, but ConEmu and the default conhost still don&#39;t (and that isn&#39;t a Clink issue).</li>
<li>Fixed screen size bug in Readline on Windows.</li>
<li>Fixed the backwards values in the <code>terminal.emulation</code> setting.</li>
<li>Fixed <code>....</code> so it works properly again.</li>
<li>Fixed case sensitive sorting of matches.</li>
<li>Fixed script error when %PATHEXT% is empty.</li>
<li>Fixed the <code>exec.cwd</code> Clink setting to default to true, so that the default behavior is consistent with how v0.4.x behaved.</li>
<li>Fixed the <code>cd</code>, <code>md</code>, <code>rd</code>, etc argmatchers to only match one argument to be consistent with the actual command syntax.</li>
</ul>
<h3 id="v114">v1.1.4</h3>
<ul>
<li>Automatically detect when running inside ConEmu and disable Clink&#39;s Virtual Terminal emulation.</li>
<li>Added <code>search-ignore-case</code> inputrc variable that makes the history search commands case insensitive.</li>
<li>Suppress adding a space after completing a flag match that ends with <code>:</code> or <code>=</code> (e.g. <code>msbuild -maxCpuCount:</code>).</li>
<li>Report any errors while loading Lua scripts.</li>
<li>Report an error if a Lua script tries to add a flag string that begins with a letter.</li>
<li>Fixed slow printing of possible matches. Readline is inefficient about emitting output, so Clink supplies a custom implementation.</li>
<li>Fixed some bugs in auto detection of flag prefix characters.</li>
<li>Fixed backward compatibility for flags, and for args when merging two parsers by calling <code>clink.arg.register_parser(&#39;foo&#39;)</code> multiple times for the same command string.</li>
<li>Fixed truncated message when the last line of a prompt exceeds 128 characters.</li>
<li>Fixed abort (<kbd>Ctrl</kbd>+<kbd>G</kbd> or <kbd>Esc</kbd>) in non-incremental history search mode.</li>
<li>Fixed saved values for settings added by Lua scripts; now the saved value is available to the script immediately on adding the setting, and saved values are retained even if the setting isn&#39;t always added by the script.</li>
<li>Fixed (and documented) shorthand form for defining an argmatcher.</li>
<li>Fixed length of colored match prefix after a path separator.</li>
<li>Fixed normalizing a slash by itself (<code>command /</code> mustn&#39;t become <code>command \</code> since that can interfere with completing flags).</li>
<li>Fixed the <code>completion-auto-query-items</code> inputrc variable.</li>
<li>Fixed the key binding list to correctly respect <code>completion-display-width</code>.</li>
<li><em>No visible effect yet: internal change that parses the input line to identify colors to use for each word (command, argument, flag, etc), but the colors aren&#39;t yet applied to the input line.</em></li>
</ul>
<h3 id="v113-alpha">v1.1.3-alpha</h3>
<ul>
<li>Fixed argmatcher lookup to be more strict, like in Clink 0.4.9 (match exact names, or name plus an extension from %PATHEXT%).</li>
<li>Backward compatibility:<ul>
<li>Most things should work now.</li>
<li>Dropping the new Clink on top of the vendor\clink directory in Cmder seems to work -- <em>but make a backup before you try this at home!</em></li>
</ul>
</li>
<li>API changes:<ul>
<li>Added <code>log.info()</code> function.</li>
<li>Added Clink version numbers in <code>clink.version_major</code>, etc.</li>
<li>Added <code>_argmatcher:getwordbreakinfo()</code> callback; removed <code>_argmatcher:setprefixincluded()</code> (it was a mess, and it was new to v1.x, so there&#39;s no compatibility concern with removing it).</li>
<li>Deprecated <code>_argmatcher:setflagprefix()</code>; now it happens automagically when using <code>_argmatcher:addflags()</code>.</li>
<li>Introduced several deprecated functions to support backward compatibility.</li>
</ul>
</li>
<li>Improvements to Lua debugger:<ul>
<li>Added <code>lua.traceback_on_error</code>, <code>lua.break_on_error</code>, and <code>lua.break_on_traceback</code> settings to make debugging script errors easier.</li>
<li>Made <code>pause()</code> consistent about pausing in the caller (rather than sometimes inside the pause command itself).</li>
<li>The debugger automatically shows the stack trace when entering debug mode, and on every pause.</li>
<li>Show 3 lines of source context by default.</li>
<li>The help list is sorted now.</li>
<li>Fixed the <code>set</code> command in the debugger to behave as documented.</li>
</ul>
</li>
</ul>
<h3 id="v112-alpha">v1.1.2-alpha</h3>
<ul>
<li>Documentation is mostly updated; just the argmatcher Lua API and Clink command line options are left to be documented.</li>
<li>Added <code>history.max_lines</code> setting that controls how many lines of command history to save (1 to 50000, default is 2500).</li>
<li>Added <code>readline.hide_stderr</code> setting that can suppress stderr output from the Readline library.</li>
<li>For backward compatibility with 0.4.8, <code>clink_inputrc</code> files are loaded as well.</li>
<li>Lua script API changes:<ul>
<li><code>addmatch()</code> in Lua scripts takes an optional match type argument.</li>
<li>Removed <code>displayable</code>, <code>aux</code>, and <code>suffix</code> fields in matches.</li>
<li>Revert the change to disallow mixing file/directory/symlink with other match types (it broke the tests and certain completion scenarios).</li>
</ul>
</li>
<li>Fixed issues:<ul>
<li><a href="https://github.com/chrisant996/clink/issues/18">#18</a> alt+digit then alt+ctrl+y isn&#39;t working.</li>
<li><a href="https://github.com/chrisant996/clink/issues/17">#17</a> arrow keys don&#39;t exit <code>reverse-search-history</code> like in bash.</li>
<li><a href="https://github.com/chrisant996/clink/issues/16">#16</a> problems with $T in doskey macros.</li>
<li><a href="https://github.com/chrisant996/clink/issues/13">#13</a> <code>clink history delete &lt;n&gt;</code> returns a CRT error.</li>
</ul>
</li>
<li>Other fixes:<ul>
<li>There should be no more problems running on Windows Insider builds because Clink now uses <a href="https://github.com/microsoft/detours">Detours</a> for hooking APIs.</li>
<li>Fixed crash in <code>insert-completions</code> due to heap failure (introduced by the performance changes for displaying matches).</li>
<li>Fixed <code>clink</code> and <code>history</code> built-in aliases (solve glitchy path problem).</li>
<li>Fixed scrolling to top of screen buffer.</li>
<li>Fixed env var and <code>set</code> completions.</li>
<li>Fixed <code>tilde-expand</code> for quoted text.</li>
<li>Fixed <kbd>Esc</kbd> in Readline&#39;s digit argument input mode (it doesn&#39;t try to cancel the mode, because that&#39;s not how Readline is documented to work).</li>
<li>Fixed exit code from some <code>clink</code> command line options.</li>
</ul>
</li>
<li>Set locale to UTF8 much earlier to avoid quirky behavior early in script processing.</li>
</ul>
<h3 id="v111-alpha">v1.1.1-alpha</h3>
<ul>
<li>Exclusively use Readline&#39;s completion implementation. This (with fixes and enhancements in Readline itself) makes the completion experience much nicer and more sophisticated, and removes a lot of code that was added in v1.0.0a0.</li>
<li>Exclusively use Readline&#39;s key binding implementation. This makes it possible to have a single consistent way to set key bindings (inputrc) and for <code>clink-show-help</code> to list all key bindings, and removes a lot of code that was added in v1.0.0a0.</li>
<li>Converted all of Clink&#39;s internal key behaviors to be implemented as commands that can be bound in the inputrc file.</li>
<li>Rewrote and refactored the pagination routine to be used in multiple places.</li>
<li>Fixed prompt filtering to correctly use the specified priority order.</li>
<li>Readline library:<ul>
<li>Updated the Readline library from v6.2 to v8.0. This picked up lots of bug fixes and new capabilities (for example colored completions).</li>
<li>Changed Readline to support backslash as a path separator.</li>
<li>The pager prompt in Readline is optionally colored, controlled by the <code>colour.interact</code> Clink setting.</li>
<li>Added <code>completion-auto-query-items</code> config variable (on by default) which asks whether to list possible matches when the number of lines listed will fill one screen page.</li>
<li>Added <code>history-point-at-end-of-anchored-search</code> config variable in inputrc to make the cursor point behave like 4Dos/4NT/TakeCommand when searching forward and backward through command history.</li>
<li>Fixed prev history at top of history.</li>
<li>Fixed to get the current values of environment variables when needed, rather than always getting the value from whenever Clink was started.</li>
<li>Fixed coloring directory completions.</li>
<li>Fixed <code>menu-complete</code> for <code>\dir</code> and <code>.</code> and <code>..</code>.</li>
<li>Fixed slow performance when displaying matches. Readline was calling stat() at least once per match (!!). A new match type field enables faster performance, coloring readonly and hidden file matches, applying filename completion rules only to filenames (vs branch names or other text strings), correct match de-duplication, and more. The Lua match APIs can supply the new match type.</li>
<li>Fixed inserting a completion to happen as a single undo group.</li>
<li>Fixed tilde to map to <code>%USERPROFILE%</code> instead of <code>%APPDATA%</code> on Windows.</li>
</ul>
</li>
<li>Typing a directory by itself uses <code>cd /d</code> to change to the directory:<ul>
<li>Typing a directory with a trailing path separator changes to the directory.</li>
<li>Typing <code>..\</code> changes to the parent directory.</li>
<li>Typing <code>...</code> or <code>....</code> etc moves up an extra parent directory level for each extra dot (2 dots move up one parent, 3 dots moves up two parents, etc). A trailing path separator is optional when there are more than 2 dots.</li>
<li>Typing <code>-</code> or <code>cd -</code> or <code>chdir -</code> changes to the previous directory.</li>
</ul>
</li>
<li>Commands that are new, enhanced, or fixed:<ul>
<li>Added <code>add-history</code> and <code>remove-history</code> commands (similar to 4Dos/4NT/TakeCommand).</li>
<li>Got the <code>menu-complete</code>, <code>menu-complete-backward</code>, and <code>old-menu-complete</code> commands working (they never worked properly before in Clink).<ul>
<li>Also added a corresponding <code>old-menu-complete-backward</code> command for reverse order.</li>
<li>All of the <code>*-menu-complete-*</code> commands support wildcards (<code>*</code> and <code>?</code>).</li>
</ul>
</li>
<li>Added <code>clink-show-help</code> command (<kbd>Alt</kbd>+<kbd>H</kbd>). The help now lists <em><strong>all</strong></em> key bindings, and it shows user-friendly key names (like <code>A-Up</code> or <code>C-x,C-r</code> or <code>C-S-PgUp</code> or <code>A-C-S-F3</code>).</li>
<li>Added <code>clink-popup-completions</code> command that shows a popup window listing possible completions. <kbd>Enter</kbd> inserts the highlighted completion.</li>
<li>Added <code>clink-popup-directories</code> command that shows a popup window listing recent directories. <kbd>Enter</kbd> changes to the highlighted directory, or <kbd>Shift</kbd>+<kbd>Enter</kbd> inserts the highlighted directory in the editing line (or <kbd>Ctrl</kbd>+<kbd>Enter</kbd>).</li>
<li>Added <code>clink-popup-history</code> command that shows a popup window listing command history. <kbd>Enter</kbd> executes the highlighted command, or <kbd>Shift</kbd>+<kbd>Enter</kbd> jumps to the highlighted command in the history (or <kbd>Ctrl</kbd>+<kbd>Enter</kbd>).</li>
<li>Added <code>clink-scroll-lineup</code>, <code>clink-scroll-linedown</code>, <code>clink-scroll-page-up</code>, <code>clink-scroll-page-down</code>, <code>clink-scroll-top</code>, and <code>clink-scroll-bottom</code> commands that do what it looks like they&#39;d do and are bound to the keys it looks like they&#39;d be.</li>
<li>Added <code>clink-expand-doskey</code> command (<kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>f</kbd>) that expands the current line according to the current doskey aliases.</li>
<li>Added <code>clink-expand-env-var</code> command (<kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>e</kbd>) that expands the environment variable at the cursor point.</li>
<li>Added <code>clink-exit</code> command (<kbd>Alt</kbd>+<kbd>F4</kbd>) that exits CMD.</li>
</ul>
</li>
<li>Fixed keyboard input issues:<ul>
<li><kbd>Esc</kbd> is a bindable key now (<code>\e[27;27~</code>).</li>
<li>Added more bindable key combinations (run <code>clink echo</code> then press keys to see the key sequence to use in the inputrc file).</li>
<li><kbd>Ctrl</kbd>+<kbd>@</kbd> (NUL) didn&#39;t work.</li>
<li><kbd>Ins</kbd> toggles insert/overwrite mode.</li>
<li>Unbound keys are ignored now, instead of inserting gibberish characters (part of the terminal internal key sequence).</li>
<li>Fixed input handling so the <code>quoted-insert</code> command can work properly.</li>
<li>Fixed <kbd>Esc</kbd> while searching.</li>
<li>Fixed vi mode (was working in v0.4.9, but not in v1.0.x).</li>
</ul>
</li>
<li>Fixed command history issues:<ul>
<li>The <code>dont_add_to_history_cmds</code> Clink setting is a space-delimited list of commands to not add to history.</li>
<li>Fixed bleeding between history banks.</li>
<li>Fixed uninitialized variable that made history updates intermittently do nothing or corrupt the other history bank.</li>
<li>Fixed output from <code>clink history</code> to convert to UTF16 when writing to the console (but write UTF8 when output is redirected).</li>
</ul>
</li>
<li>Fixed terminal output issues:<ul>
<li>Added <code>terminal.emulate</code> Clink setting that controls whether Clink does VT emulation or passes all ANSI escape codes directly to the console host. For example, this lets the prompt and completion coloring take advantage of more sophisticated ANSI escape codes such as XTerm 256 color and 16 bit color support.</li>
<li>Added back support for the <code>prefer-visible-bell</code> config variable.</li>
<li>Fixed underline support.</li>
<li>Fixed handling for UTF8 output from Readline.</li>
<li>Fixed invisible cursor point in Lua debugger.</li>
</ul>
</li>
<li>Completions:<ul>
<li>Added <code>match.sort_dirs</code> Clink setting that specifies where to sort directories in the list of possible completions: before files, mixed in with files, or after files.</li>
<li>Don&#39;t attempt completing incomplete UNC paths: at least the <code>\\server\share\</code> path components are required (for anything shorter the OS APIs are guaranteed to fail, but will fail slowly).</li>
<li>Fixed sorting to use Unicode aware locale based sorting (like Windows does) instead of dumb UTF8 byte comparisons.</li>
<li>Fixed arbitrary limit on completions (had been limited to 64KB worth of completions).</li>
<li>Fixed quoting spaces in completions.</li>
<li>Fixed to use the same list as CMD for characters that require quoting.</li>
<li>Fixed normalizing UNC paths.</li>
<li>Fixed volume relative completions (e.g. <code>x:foo</code>).</li>
<li>Disallow mixing file/directory/symlink with other match types. This was to avoid a confusing/malfunctioning case in match display and prefix highlighting.</li>
</ul>
</li>
<li>Fixed UTF8 encoding in various Lua functions.</li>
<li>Fixed printing stderr output from Readline, Lua, and Clink.</li>
<li>Fixed crashes and other failures when starting Clink in 32 bit CMD.</li>
<li>Fixed some memory leaks that accumulated with each new line of input.</li>
<li>Fixed prompt filtering API to be backward compatible with v0.4.9 scripts.</li>
<li>Fixed Lua errors from <code>clink set</code> (it neglected to fully initialize Clink&#39;s Lua integration before loading Lua scripts).</li>
<li>Fixed UTF8 conversion bug that could truncate a string without fully converting it.</li>
<li>Fixed serious rampant memory corruption bug in v1.0.x (not present in v0.4.9), which had been causing intermittent malfunctions and data corruption and crashes.</li>
<li>Fixed multi-line doskey macros to show the prompt in between lines, like CMD does.</li>
<li>Removed the 4096 byte limit on input.</li>
<li>Renamed the Clink DLL back to what it was in v0.4.x, to fix compile time problems.</li>
<li>Other fixed issues:<ul>
