This allows "vendors" (i.e. third-party upstreams interested in
supporting fish) to add auto-loaded functions and eager-loaded
configuration "snippets", while still allowing both the user and the administrator to
fully override all of that.
This has been inspired by systemd's configuration hierarchy, and implements a similar scheme
whereby files with the same name in higher-ranking directories override files in lower-ranking ones.

Fixes the invocation of a user-specified browser by the `help` command on Cygwin.
- Use `cygstart` to launch the browser with escaped quotes to avoid problems with spaces in the path to the browser, (e.g. Program Files).
- Use `cygpath` to convert the base help dir to a Windows path before constructing the fie URL to pass to the browser.
This changes the default escape timeout for the default keybindings (emacs
mode) to 300ms and the default for vi keybindings to 10ms.
I couldn't resist fixing a few nits in the fish_vi_key_bindings.fish file
since I was touching it to set the escape timeout.
It used to be that way and we recommend `set fish_greeting` (i.e. set to
empty) in the docs - possibly since we check if the variable is defined
on upgrade.
This is meant to make it clear that fish cannot control the terminal
window background color. It also augments the set_color documentation to
describe how it decides which color the terminal can display.
Resolves#2421.
Resolves#2184.
To implement this mostly as a wrapper around pactl, we add the list of
commands for this to that. It's 90% the same anyway. (This means that
`pactl suspend ` will complete files instead of commands like `pactl
banana ` would, but neither is correct)
This fails on e.g. an abbr that uses `env a=b`, like the included test demonstrates.
Unfortunately it decreases the speed again (2s vs 2.2s vs 4s original),
but correctness is more important.
- Replace __fish_abbr_escape with `string escape`
- Don't double-parse the key
- Replace IFS magic with string
Together, this seems to speed it up by a factor of about 2.
Unfortunately, nvim will, even when running in a terminal that supports
it, swallow the sequences whole, rendering the displayed text _white_.
This means falling back to 256 colors is the lesser evil as at least a
blue-ish color will display as blue while a red-ish will be red, instead
of both showing white.
nvim's behavior does _not_ change depending on
$NVIM_TUI_ENABLE_TRUE_COLOR or any other option I could find and neovim-qt
exhibits the same behavior.
Fixes#2600.
This patch is currently floated from the NixOS side as part of
https://github.com/NixOS/nixpkgs/pull/12000, but prior versions of the
hook ignore anything but the first argument anyway, so this is
backwards-compatible.
This skips the weird dance where we'd define a simple handler and then
later overwrite with a fancier one, once the first event came in.
It turns out that isn't necessary, as it doesn't actually improve
startup speed because the checks needed to define fancier handlers are fast.
In case we are non-interactive, still define the simple handler, and
keep the default handler for users to switch to.
That's probably the part where commit hashes are most used, we can add
the other subcommands later.
This generates a _lot_ of options, so hooking it up everywhere would be
unwise, though our pager helps quite nicely with filtering - typing
"Branch" will filter out the commits, and typing other things will
filter the subjects, which is quite cool.
This turns '\040' into a space. /etc/mtab also supports other
escapes ("\\" for backslash, "\011" for tab), but I can't find
documentation for those in fstab.
This adds blockdevices (and directories) and fixes the regexes to no
longer include comments but include UUID= and LABEL=, which at least
util-linux mount understands.
It also shouldn't fail on systems without fstab any longer (like default OSX).
Fixes#2606.

Unfortunately, there's no standard way to detect support (importantly,
terminfo doesn't encode it), but there's a variety of terminals that

It's better than letting this functionality go to waste.
Check KONSOLE_PROFILE_NAME instead of DBUS_SESSION because Konsole can be compiled without dbus support.

This does a number of things:
- Removing trailing space from suggested repos for hg.
- Use the string builtin for hg completions.
- Add more internal merge tools to hg completion.
- Enable completions for abbreviated hg commands.
- Stop completing a deprecated hg branches option.
- Properly match the hg subcommand when preceeded by global switches.
- Stop completing deprecated hg glog.
- Complete hg config instead of showconfig.
- Properly complete when global switches are before the hg command.
- Properly handle the repository switch for hg completions.
- Properly handle the hg global switch cwd.
Currently if there is a conflict with two manpages having the same
name, one completion will override the other. But if one can be parsed
and the other can't the one with parsed results will always have a
higher priority.
It seems smart to only let files be parsed that are clearly
manpage files. Other files wouldn't be openend by man so
I think it is safe to guess that only these files are man
pages.
Allows the length of each shortened path component to be customized by setting the `fish_prompt_pwd_dir_length` variable to the number of characters to include (plus a leading dot because that's special). Maintains the default behavior of shortening path components to just one character. You can also set `fish_prompt_pwd_dir_length` to an empty or invalid value or 0 to disable shortening completely.
This reduces code duplication and adds some previously unavailable
bindings that don't quite _violate_ the vi-principle (like
prevd-or-backward-word on alt-left) and matches other "impure" bindings
like \cf for forward-word (a quite emacs-ish binding) we already have.
Fixes#2412Fixes#2472Fixes#2255
For cygwin, you can't `cd C:`, so a prompt of "C:/Something" is
misleading.
For OSX, we dereference symlinks elsewhere
This also simplifies prompt_pwd quite a bit.
Not for _everything_ because that causes too many options to be
generated (which is an issue for git as it is), but for modified, staged
and added files - which is where it is most useful.
Fixes#901 as far as I'm concerned.
git has options that can appear before commands, but not all of
them, and some of them need an argument. This means
`__fish_seen_subcommand_from` will give too many false-positives, while
`[ (count $cmd) -eq 2 ]` will give too many false-negatives.
Instead go through all arguments and check if they are in that list of
options that can be before a command and skip the argument for them, if
any.
This is to the benefit of systems with ancient GNU sed, which does not
recognize "-E", but only "-r".
Fixes#2305 - even if it doesn't replace all `sed -E` invocations in the
codebase, the others are unlikely to occur on CentOS and other similarly
crusty systems.
`__fish_apm_using_command` was incorrectly taking lists of commands, new function added to support multiple a command having synonyms.
Simplify switch statement
Also remove superfluous function.
Allow for multiple completions after a command
Useful for removing packages, will complete for more than one.
Code improvements
`sort -u | uniq` is completely redundant, calling grep for every
status-pair is unnecessary, `contains` doesn't take the word "in" as
special.
None of these are critical and there's basically no performance benefit
since this function is utterly dominated by hg calls.
This doesn't add anything except slowing the function down by about
33%. Checking for a branch is just as good and that is displayed in the
prompt anyway.
According to the newer code below:
xdg_data_home = os.getenv('XDG_DATA_HOME', '~/.local/share')
the actual default path is ~/.local/share/fish/generated_completions/
This is used in at least 4 places, all of which have a bug in that they
print "options" as a valid repo. It seems better to fix it once,
especially given that there are tons of AUR helpers and pacman wrappers,
all of which might need this info.
net_tools, which provides `ifconfig` and `netstat`, among other things,
has last been updated in 2013. This means `ifconfig` on linux is
basically dead.
Instead of ifconfig, use `ip` (from iproute2), which is much more powerful and
provides a much more annoying commandline syntax.
Instead of netstat, just look at /sys/class/net.
fish_user_key_bindings is the user's, and they should know if they want
vi-ish bindings or emacs-ish (or nano-ish). If they want to define
multiple, they can also do that (e.g. via checking what
$fish_key_bindings is set to).

Make overriding cnf-handler work
Do this by renaming the __fish_command_not_found_handler used during
startup to __fish_startup_command_not_found_handler. That allows us to
check if __fish_command_not_found_handler has been defined and skip the
setup of the normal one.
Now disabling cnf-handling can be done via defining an empty
__fish_command_not_found_handler in config.fish
This adds a special colorscheme and prompt function guaranteed to work
on a VT and activates them automatically if $TERM = "linux".
set_color is overridden to only allow the 8 colors VTs have (under the
assumption those are always the same) and the color variables are
shadowed with global ones so they don't pollute our nice capable terms.
This is already done by fish before calling the completion.
It breaks completion with combiners (#2025) and also with wrappers.
(This does not include git because that's better solved in #2145)
There are two main problems in the existing Fossil autocompletion that this
patch solves:
* Because Fossil lacks an alias system similar to those in Hg and Git,
wrapper scripts are common, and aliasing them to `fossil` is also fairly
common. The lack of the `command fossil` pattern in the completions script
meant that the actual fossil command might not be called, but rather the
alias. This problem has been fixed by introducing a __fish_fossil command,
similar to the __fish_hg and __fish_git commands in those completion shells,
that does this, and converting all explicit fossil calls in the completion
script to use __fish_fossil instead
* Because there's now a centralized location for calling Fossil, I also moved
all of the repetitive stderr redirects that function.
This results in more robust and cleaner code.
This was too simplistic, among other things it completed things that
looked like key ids but weren't, didn't turn "\x3a" back into
colons (which made the argument invalid)....
gpg is weird.
Might fix#2150
Bit one: Make all the fossil command invocations throw away stderr so we don't
get annoying messages when not in a repository.
Also:
- Move checkout into alphabetical order.
- Fix ls to complete against tags for -r option, not no option.
- Add missing option to delete command.
- Make commit complete against modified files.
- Make add only complete against extra files.
- Remove now ununused function to list extra & modified files.
- Add -f option in a number of places where it seemd appropriate.
__fish_complete_mime used in that way is a no-op on current fish anyway,
and emacs is by no means useful for just text files (it can also view
PDFs, images, ...).
Otherwise this completion currently only offers options, not arguments.
For most these are pretty much incompletable (lisp code, for example),
and for others it's just not all that useful.

This used to be a function because we didn't have complete -w
Use that and it becomes a bit simpler.
This also simplifies the code in a few other ways (like removing a
useless-use-of-cat)
and adds comments about a few edgecases.
New sample prompt from Acidhub (github.com/acidhub)

changed `function __trap_handler_EXIT --on-exit %self` to `function __trap_handler_EXIT --on-process-exit %self`
I'm guessing the on-exit syntax was from an older version? Trapping EXIT with that syntax caused errors.
The following behaviour is added:
- an empty pushd exchanges the top two directories in the stack;
- pushd +<n> rotates the stack so that the n-th directory (counting from the left of the list shown by dirs, starting with zero) is at the top;
- pushd -<n> rotates the stack so that the nth directory (counting from the right of the list shown by dirs, starting with zero) is at the top.
1. When run with no arguments, make abbr do the equivalent
of `abbr --show`
2. Enable "implicit add", e.g. `abbr gco git checkout`
3. Teach `abbr --show` to not use quotes for simple cases
4. Teach abbr to output -- when the abbreviation has
leading dashes
Add some basic tests to abbr too.
Add a new function fish_mode_prompt which (if it is defined) has its output
prepended to the left prompt. Rather than replacing the prompt wholesale, make
fish_vi_mode enable this function by setting a variable __fish_vi_mode. This
enables vi mode to interoperate nicely with custom prompts. Users who want
to change how the mode is reported can either redefine this function or
erase it entirely. Fixes#1988.

Notification is sent using an OSC 777 escape sequence as described at
http://known.phyks.me/2014/local-notifications-for-weechat-and-urxvt.
The specific notification is crafted to match that emitted by bash
when running under Fedora 22 with the "vte-profile" RPM installed.
See the code for "__vte_prompt_command" starting at
http://pkgs.fedoraproject.org/cgit/vte291.git/tree/vte291-command-notify.patch#n307
to see exactly what bash produces. My approach is, however, a bit
more paranoid about control characters embedded in commands.
Gnome-terminal 3.16 responds to this escape sequence by posting a
desktop notification if the containing terminal window does not have
focus. This lets the user know that a long-running background command
has completed. Job notification is promoted as a Fedora 22 feature
(http://fedoramagazine.org/terminal-job-notifications-in-fedora-22-workstation/),
so it would be good for fish users to be benefit from it.
Conversely, anyone who does not want this feature can use "functions
--erase __notify_vte_command_completed" to turn it off.
With the fix for #365, fish_command_not_found event handlers
receive the command and all of its arguments. But commands
like /usr/lib/command-not-found expect only the command name.
So when invoking an external command, just pass the command
name, not all of the arguments.
In 73f344f41b, we allowed autoloaded functions to be deleted.
For some reason, funcsave immediately deletes the function it
creates. This previously did very little, since the function would
immediately be re-autoloaded, but with the fix for 73f344f41b
the function gets tombstoned. So the effect is that funcsave
makes the function disappear! This simply removes the erase call,
which dates back to fish 1.x.
It seems that `ul` can't handle the escape sequences for bold text that `nroff` generates on my system. Fixed by either removing `| ul`, or adding `-c` to the `nroff` command.
Needs testing for old (OSX?) versions of nroff.
Unfortunately, list-unit-files doesn't understand --state=loaded
This needs a new function to explicitly use list-units
This reverts commit 9f521b7694.
Support for space-delimited abbreviations was added to the expansion
parser in fbade198; this commit extends that support to the user-facing
tools, and documents the space-separated behaviour. Equals-delimited
abbreviations are expected to be removed before the next release.
Work on #731.
There is no CTRL-C handler for the default mode in the vi bindings. This makes it difficult to say "never mind" and start a new command line like you can do in bash's vi mode.
There were CTRL-C handlers for insert and visual modes that go back to default mode, but nothing happens in default mode. I copy-pasted the CTRL-C handler from the default key bindings file.
(Ideally, the behaviour of git could be implemented: pipe the input
through a pager iff the length is > window size and in interactive
mode).
Closes#1076.
The terminal width magic that __fish_print_help learned doesn't help
when builtin_print_help runs it in a subshell. Instead, add an
undocumented --tty-width flag to __fish_print_help that's used to pass
the terminal width.
As a result of this rewrite, the output now:
* Expands to fit the terminal width, like `man` does
* Preprocesses the manpage with `tbl` just in case, since `man` does
this, even though I doubt any fish manpages use `tbl` formatting.
* Handle bold/underline with the `ul` command as it was designed for
instead of trying to fake it with `sed`.
* Compresses blank lines as `man` does with the default `less -is`
pager.
The usage is still the same, but it's a lot more robust, and also no
longer assumes $fish_user_abbreviations must be a universal variable.
This also fixes the unexpected error output when calling `abbr -a` with
no existing abbreviations.
Calling `abbr -a` with an abbreviation that already exists now silently
overwrites the abbreviation, just like `function` and `bind` do, instead
of complaining.
This fixes the issue with nonexistant directories (some Linux
distributions put these for local modules), and also fixes the
issue of dot meaning any character instead of simply dot.
# The first commit's message is:
Simplify default fish_prompt
No need for the set_color caching now that it's a builtin.
Also simplify the 3 classic prompts in fish_config's sample_prompts set.
Remove comment that AFAICT is not true anymore.
Ensure someone setting __fish_active_key_bindings as a universal
variable doesn't screw up the initial keybinding load.
All opam subcommands and descriptions are covered, along with
all the flags that are common to all commands. However, only
`opam config` has complete subsubcommand coverage.
Apparently, in zsh, Meta+H can be used to display the manpage for
the current command. This commit adds this zsh feature to fish shell.
The F1 keybinding is left, although it's now secondary according to
fish help, as some terminal emulators don't let the user press F1 key.
Use the new `read -z` flag to complete git aliases better. This approach
won't break if an alias contains a newline.
Also fix stash completion, which was broken on BSD sed.
