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.
Closes#8874
micro only parses the [FILE]:LINE:COL syntax
if the parsecursor option is enabed
in the meanwhile, the +LINE:COL syntax is unambiguous and always valid
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.
* Print message in set_fish_path -v when a path doesnt exist

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

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.
- Do not capitalize sentence fragments
- Use the modality where problem input is in a %s: prefix, then
is explained.
- Do not address the user (the "You cannot do ..." kraderism)
- Spell out 'arguments' rather than 'args' for consistency
- Mention 'function' as a scope
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
matter of shell configuration. The main problem is the malfunction of
the delete key, so we have to use a workaround like this.
* Hide whatis database building from the user
It's really an internal detail, but shows up in prompts that display how many
background jobs are running.
By disowning it keeps running but won't show up in `jobs` or get killed if the user
exits the shell.
* Update __fish_apropos.fish
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".
(also give up on the line breaking because it makes it annoying to do
automatically)
Fixes#8245.
This was semi-automated with
```fish
for file in $argv
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
end
```
(where $argv contains the path to faq, fish_for_bash_users,
interactive, language and tutorial.html)
Building help.fish at compile time would work, but only for users who
build the docs.
As functions know where they are loaded from now, there is no point in
them being marked as loaded from a temporary file that has been removed.
Source the function via a redirect instead.
Ubuntu's fish package on WSL 1 has xsel as recommended dependency,
even though there is no X server available. This change makes us
use Windows' native clipboard even when xsel is installed.
We keep __fish_is_nth_token for compatibility and edit the
implementations of __fish_is_nth_token, __fish_is_first_token and
__fish_is_token_n to use fish_is_nth_token
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
