This reimplements ridiculousfish/control_r which is a more future-proof
approach than #6686.
Pressing Control+R shows history in our pager and allows to search filter
commands with the pager search field.
On the surface, this works just like in other shells; though there are
some differences.
- Our pager shows multiple results at a time.
- Other shells allow to use up arrow/down arrow to select adjacent entries
in history. Shouldn't be hard to implement but the hidden state might
confuse users and it doesn't play well with up-or-search, so this is
left out.
Users might expect the history pager to use subsequence matching (fuzzy
matching) like the completion pager, however due to the history pager design it
uses substring matching. We could change this in future, however that means
we would also want to change the ordering from "reverse-chronological" to
"longest common subsequence" (e.g. what fuzzy finders do), because otherwise
a query "fis" might give this ordering:
fsck /dev/disk/by-partlabel/Linux\x20filesystem
fish
which is probably not what the user wants.
The pager shows only a small number of history items at a time. This is
because, as explained above, the history pager does not support subsequence
matching, so navigating it does not scale well.
Closes#602
This can be used to print the modification time, like `stat` with some
options.
The reason is that `stat` has caused us a number of portability
headaches:
1. It's not available everywhere by default
2. The versions are quite different
For instance, with GNU stat it's `stat -c '%Y'`, with macOS it's `stat
-f %m`.
So now checking a cache file can be done just with builtins.
/etc/hosts specifies, that everything after a #-character is to be
treated as a comment. The current __fish_print_hostnames however only
considers #-characters at the beginning of a line.
Thus the comment from following valid hosts-entry would end up in the
completion output:
1.2.3.4 myhost # examplecomment
getent hosts properly handles comments.
When we want to print something while the prompt is still active, we move the
cursor by printing a newline for each line in the prompt beyond the first
one. As established by 80fe0a7fc (fish_job_summary: Format message better
for multiline prompts, 2022-06-28), our use of "string repeat" actually
prints an extra newline. Let's remove it here as well.
This was supposed to be number of lines in the prompt minus 1, but
string repeat added one.
Also it triggered even in case of the stopped job message, which is
already repainted differently.
So we add it when we need to repaint ourselves.
As a bonus add a newline before in that case so the message isn't
awkwardly printed into the commandline.
Fixes#9044.
Discussions with the tmux maintainer show that:
1. We no longer need the passthrough sequence at all (and it's
deactivated by default)
2. Tmux can check if the outer terminal supports cursor shaping
Fixes#8981
This commit lets you check the manpage for a leading command by moving
the cursor over it, matching the behavior of tab complete.
It also lets you select the man page for the base of a two-part command
like `string match`.
The additional regex case is added because
`commandline -t` returns an empty string when the cursor is after a
space, e.g. at the end of 'sudo ', which the later checks don't handle.
This diagram shows the manpage picked for different cursor positions:

The recent improvements to multiline prompts and vi-mode in #3481 appear
to be sufficient to make iTerm2 well behaved, so remove our hack which
disabled it by default.
Fixes#3696
This removes the awkward secondary logic.
Note that we still ship a function called `__terlar_git_prompt`
because people who picked the prompt will still be calling it - we
don't update the prompt.
This makes it so
1. The informative status can work without showing untracked
files (previously it was disabled if bash.showUntrackedFiles was
false)
2. If untrackedfiles isn't explicitly enabled, we use -uno, so git
doesn't have to scan all the files.
In a large repository (like the FreeBSD ports repo), this can improve
performance by a factor of 5 or up.
Previously, `kill-whole-line` kills the line and its following
newline. This is insufficient when we are on the last line, because
it would not actually clear the line. The cursor would stay on the
line, which is not the correct behavior for bindings like `dd`.
Also, `cc` in vi-mode used `kill-whole-line`, which is not correct
because it should not remove any newlines. We have to introduce
another special input function (`kill-inner-line`) to fix this.
Arguments to --ignored were introduced in Git 2.16, from January 2018.
The git completions specifically work around this, allowing older
versions to be used; match this in the git prompt.
Fixes the tests on CentOS 7.
When switching this to use `git status`, I neglected to use the
correct definition of what a "dirty" and a "staged" change is.
So this now showed already staged files still as "dirty".
Fixes#8986
edit_command_buffer uses the "norm" command for moving the cursor to a column
with the "|" primitive. The problem is that the user can remap "|". Fix this
by using the "norm!" variant which ignores user mappings (see ":h norm").
Closes#8971
Previously, running `fish_add_path /foo /foo` would result in /foo
being added to $PATH twice.
Now we check that it hasn't already been given, so we skip the
second (and any further) occurence.
man-db's man 2.7 as shipped in OpenSUSE fails to set a non-zero
exit code when invoked like "man ls-some/dir". This means
that we fail to display the man page if the commandline is
"ls some/dir". Work around this by never treating tokens
with slashes as subcommand.
Pressing Ctrl-D while a command is running results in a null key code in
our input queue. That key code is bound to insert a space (without expanding
abbreviations). Make it only insert a space if the commandline is non-empty,
to accommodate this use case.
This probably affects other keys as well.
Closes#8871
As we've noticed a few times now, mingw/msys/cygwin has a fairly
horrible kill implementation that annoys us here.
However our workaround wasn't enough - "mingw" is also a name that is
used here and "msys" can also be a substring.
Also we need to silence the `kill` because it's better to not list the
signals than it is to spew errors.
Fixes#8915.
Some terminals can be configured to send variuos escape sequences for keys
that could historically not be detected. Turns out some usage pattern rely
on those quirks.
Shift+Space is easy to mistype when wanting to insert a space (especially
when typing ALL CAPS). Map it to Space, to match user expectations.
Similarly for Control+Return, for which xterm can be configured to send
something other than \cr:
echo 'XTerm.vt100.modifyOtherKeys: 1' | xrdb && xterm
I'm working on a change to builtin bind that allows to bind CSI sequences via
human-readable key names (#3018) but for now let's just map the raw sequences.

micro only parses the [FILE]:LINE:COL syntax

You can use an index with vared, like `vared PATH[4]`. However this was
inadverently broken in fa2450db30, because you cannot use `read` to
modify an element of a variable, only the whole variable. Fix this.
Unfortunately this means using another local variable, so we name it
__fish_vared_temp_value instead of just temp so that collisions are
unlikely.

As explained in the parent commit, if we print things to the command line,
we move the cursor down before redrawing a multi-line prompt. This is a
workaround to avoid erasing what we printed.
We forgot to do add this workaround to fish_job_summary. When running
`sleep 1 &` with a multiline prompt, the job exit notification is immediately
overwritten (most of the time). This can be observed consistently on Linux
by waiting before redrawing:
diff --git a/share/functions/fish_job_summary.fish b/share/functions/fish_job_summary.fish
index a552fabbc..f457ee8e8 100644

end
Move the cursor down to work around this. In future, we could avoid calling
fish_prompt. Also, this solution add an extra blank lines before the next
prompt. With a real fix, we could get rid of that. Even worse, sometimes
there are two blank lines instead of one (for a two-line prompt).
Fixes#8817
We have some key bindings that print directly to the terminal while the user
is still typing the command line. Thereafter, we redraw the command line,
so the user can resume typing. To redraw a multiline command line, we first
erase several lines above the cursor. To not erase the key bindings' output,
we move the cursor down that many lines.
Simplify the logic; no functional change.
This conditionally set a function variable in an unsafe way.
If you do something like
```fish
if condition
set -f foo bar
end
```
then, if the condition was false, $foo could still use a global variable.
In this case, alias would now fail if a variable $wraps was defined globally.
This reverts most of commit 14458682d9.
The message rewording can stay, it's *fine* (tho it'll break the
translations but then we'd need a real string freeze with a
translation team for those to be worth anything anyway, soo)
This was already apparently supposed to work, but didn't because we
just overrode errno again.
This now means that, if a correctly named candidate exists, we don't
start the command-not-found handler.
See #8804
The tmp and prompt variables collide with variables used as arguments.
Just avoid them entirely, at the cost of making the internals of the
functions somewhat more complicated.
Closes#8836.
This tried migrating old abbreviations *twice* - once from the 2.3
scheme to the 2.4 one, and once from that to the 3.0 scheme.
Since this is purely for upgrading from fishes < 3.0, and basically
untested, let's remove it.
If anyone does that upgrade, they'll simply have to reexecute the abbrs.
Because we reload changed function files, a common issue on upgrading
to 3.4.0 is that fish_title causes errors.
So we simply use the oldschool syntax.
I have no idea why this kept one component in the one case and none in
the other.
Because we already aggressively shorten the command, we can keep the directory.
Some GPG options work only with private keys but our completions suggest all
keys. Modify `__fish_complete_gpg_user_id and __fish_complete_gpg_key_id`
to take an optional argument for the "key type" to override `--list-keys`
with like `--list-secret-keys` for the appropriate options.
Closes#8712
Their names are not perfect, so let's keep them as internal functions,
until we figure out how/if we want to expose this.
This reverts 0445126c2 (Undunder __fish_is_nth_token, 2021-06-29) (but I
did it without "git revert").
Closes#8008
Completions may benefit from using these in tandem to dynamically generate
completions predicated on the value of an earlier token in a cleaner fashion.
(Currently, most of called completion helper functions introspect the command
line to get the value of an earlier argument, making them less reusable for
different expressions that need completions of the same type. This way, the
completion can provide the function with the argument value explicitly.)
We detect one terminal (foot) with a "string match" command, and all others in a long "test"
command. Let's put the detection of each terminal on a new line. This should be easier to read
and change. It also allows to lose one level of indentation.
This was an undocumented undunderscored function that wouldn't be
super useful to actually use manually (because it still checked if the
variable was set!). It also relied on `__init_uvar`, which was only
set in `__fish_config_interactive`.
Additionally it didn't remove any complexity because this was all very
simple "do thing a, do thing b, do thing c" stuff. It added a layer of
indirection instead, and made fish startup dependent on another
function.
If you want to reset your colorscheme to the default, use fish_config.
- Use named colors instead of hex values - not sure how this
happened in the first place, these all map to basic named colors.
- Reinitialize if these were last set on fish <3.4, new variables
have been added.
- Break this into a separate function for the sake of
__fish_config_interactive complexity, and allow for running
manually.
GNU tr is not Unicode-aware, and was corrupting descriptions that had
non-ASCII characters.
Additionally, rather than using the Unicode private use characters, use
the ASCII/UTF-8 record separator character as it was intended.
The sed command could probably be rewritten to do all the heavy lifting
here, but would be even less readable.
Closes#8575.
fish_git_prompt may run certain git commands which may invoke certain
external programs as specified `.git/config`. Prevent this by suppressing
certain git config options.
This looked at __fish_print_commands, which goes via our man pages to
find the commands (it shouldn't, buuut), and exludes a hard-coded list
of pages.
So we do two thigns:
1. We add the other doc pages to the list
2. We check commands *later* - if we listed something explicitly it
should be used
This was supposed to act like `type -q` or `command -q`, in that it
returns 0 if at least 1 exists.
But because it used the wrong variable it didn't.
Fixes#8431.
Foot has several terminfos:
* foot - the default one
* foot-direct - 24-bit color terminfo, similar to xterm-direct (used by e.g. emacs)
* foot-extra - alternative to the ncurses provided terminfo, with a couple of extra, non-standard
capabilities
* foot-extra-direct - 24-bit color version of the above
There may also be other distro-custom terminfo names (serving the same purpose as foot-extra*)
This is nroff/groff being broken. It turns "→" into "â". This is even if we select `-Tutf8` and friends.
So, if mandoc exists, we prefer that, and otherwise, run preconv on
the file first (if it exists).
Really, what we would need to to is tell nroff to pass `-KUTF-8` to
groff, but that doesn't appear to be possible.
- Introduce BUILTIN_ERR_COMBO2_EXCLUSIVE
- Distill generally more terse, unambiguous error descriptions.
Remember English is not everyone's language.

In 'simple terminal' the delete key prints \e[P by default, which is
related to the different approach the authors of st are taking on the

the delete key, so we have to use a workaround like this.
* Hide whatis database building from the user

By disowning it keeps running but won't show up in `jobs` or get killed if the user

The less -F / --quit-if-one-screen option is buggy before v530. To work
around this, pass --no-init less versions older than 530.
The --no-init option was previously passed; it was removed in d15a51897d
for mouse support. Unfortunately it looks like we can't have mouse
support and --quit-if-one-screen on macOS shipped less (version 487).
It's worth fixing this because otherwise history and help is just not
printed on stock macOS.
Relevant is https://unix.stackexchange.com/questions/107315/less-quit-if-one-screen-without-no-initFixes#8157.
Commit c3374ffd0 ("Use read --tokenize instead of eval for $BROWSER &
$EDITOR") converted uses of "eval" for environment variables to use the
safer "read -at", which performs word splitting but no other expansion.
funced contained a leftover instance of "eval". Remove it in favor
of using the editor command that was already word-split.
This means that we don't accidentally evaluate the file name.
(Also "set -gx EDITOR=~/my-editor" won't work anymore because the ~
is not expanded anymore but no one has complained about that behavior
in edit_command_buffer.)
Fixes#8289
*Problem:*
edit_command_buffer uses `cat` to return the modified content.
If a person has an alias for `cat` to a different command such `bat`** the editing will not be useful anymore since bat decorates the text with frames, line counts, etc
*Solution*
Appending command to cat, fish will ignore the alias and execute the real command according to this https://fishshell.com/docs/current/cmds/command.html
** https://github.com/sharkdp/bat
This should add all the sections that aren't linked internally,
including "identifiers".

set -l varname (string replace -r '.*/(.*).html' '$1' -- $file | string escape --style=var)pages
set -l sections (string replace -rf '.*class="headerlink" href="#([^"]*)".*' '$1' <$file)
echo set -l $varname $sections

interactive, language and tutorial.html)
Building help.fish at compile time would work, but only for users who

Ubuntu's fish package on WSL 1 has xsel as recommended dependency,
even though there is no X server available. This change makes us

This injected filenames into fish script, which could inject things
that looked like fish script.
E.g. create a file called `~/.config/fish/themes/"; rm -rf ~/*"`.
Note that the prompts are all shipped by us, but the themes can
technically be added by the user, and they might not be dilligent in
what filenames they allow.
`fish_config theme`:
- `list` to list all available themes (files in the two theme
directories - either the web_config/themes one or
~/.config/fish/themes!)
- `show` to show select (or all) themes right in the terminal - this
starts another fish that reads the theme file and prints the sample
text, manually colored
- `choose` to load a theme *now*, setting the variables globally
- `save` to load a theme and save the variables universally
- `dump` to write the current theme in .theme format (to stdout)
- `demo` to display the current theme
This introduces two functions to
- toggle a process prefix, used for adding "sudo"
- add a job suffix, used for adding "&| less"
Not sure if they are very useful; we'll see.
Closes#7905
I almost always use this on the last/only job in a commandline, so
the semicolon is usually not needed. We have always added it but I
prefer not dropping it: this feels cleaner because it's what you'd
type without the shortcut.
Similarly to b0e3cc4b5 (__fish_complete_suffix: Remove `eval`,
2019-12-28), this use of eval is unsafe and can spew errors if
invoked on an incomplete brace expansion.
Commit d15a51897 ("Rationalize $LESS uses") switched a "less" flag
from -r (interpret all control characters)
to -R (interpret only color codes)
Somehow this changed the output of "fish -c 'command -h'" to include
weird characters:
DESCRIPTION^O
command^O forces the shell to execute the program COMMANDNAME^O and ignore any functions or builtins with the same name.
Probably this was the reason why I originally used -r over -R. Anyway,
-R is safer and it looks like we can just remove the "ul" preprocessing
since "less" will interpret bold/underline just fine.
This has one slight behavioral change: Even with xsel, it now copies
to the clipboard, not the primary. I would imagine anyone who cares
about the primary selection has customized fish_clipboard_copy and
because we never got a bug about this not supporting anything but
xsel (and errorring out if it's not available!) this is probably
unused.
So now we support all the clipboard integration things, and we use the clipboard.
This change adds a binding that sets the s key's behaviour to match
the c key's in visual mode. This mirrors vim's behaviour (see `:h v_s`
in vim or neovim).
Apart from OpenBSD's "colorls" that is basically an ls that can do
color, there's also a ruby tool called "colorls" that's closer to exa.
Ignore that one since the options it understands are quite different
and I'm betting it's slower (given my experience with ruby tools).
See #8042.
* add support for colorized ls on openbsd
* add changelog line for colorls support
* add readme line for colorls support

Stop using "--no-init"/"-X" because we have no actual reason to and it
may break mouse initialization on my best friend macOS.
Use --RAW-CONTROL-CHARS, the capital version that only lets through
specific escape sequences, not *everything* - we shouldn't have
anything weird here, but less heavily discourages the other version.
Allow a user's $LESS to override.

This isn't really a "locale" variable as such. It has no effect on
encoding and stuff, it's just the output language.
What we really want here is get something better than the awkward "C"
or "POSIX" for LC_CTYPE specifically - everything else doesn't really
matter.
From my checks (gnome-terminal with the "gnome light" colorscheme)
this seems to be the only color that's barely visible in a light
terminal, and it's the only color mentioned in both bug reports.
I'm leaving the artistic decisions to others, this is now *acceptable*
in both.
Note that, because we use universal variables here (hint #7317), this
will only be changed for preexisting installations when the user
reloads the colorscheme.
