To make it more familiar to vi/vim users.
In all mode, ctrl-k is bind to kill-line.
In Vi visual mode:
* press v or i turn into normal or insert mode respectively.
* press I turn to insert mode and move the cursor to beginning of line.
* because fish doesn't have upcase/locase-selection, and most people reach for
g-U rather than g-u, g-U binds to togglecase-selection temporarily.
Testing has revealed some problems on BSD and Windows terminals and
the Linux Console, let's revert to the old implementation until these
are fixed. Leaving the changelog entry for now since it shouldn't
take long.
See #11003
jj is often colocated with Git so the Git prompt also works, but
jj is always in a detached HEAD state, which is atypical for Git.
The jj prompt improves things by showing the revision ID which is
usually more useful than the commit ID.
This prompt is mostly adapted from the defaults for "jj log -r @".
Showing conflicting/empty commits seems useful.
Also perhaps bookmarks and tags, not sure.
The main problem with this prompt is that due to --ignore-working-copy,
the information may be stale. That will be rectified after every jj
command, so hopefully this doesn't cause issues.
Fixes#10980.
This would, if a commandline was given, still revert to checking
the *real* commandline if it was empty.
Unfortunately, in those cases, it could have found a command and tried
to complete it.
If a commandline is given, that is what needs to be completed.
(note this means this is basically useless in completions that use it
like `sudo` and could just be replaced with `complete -C"$commandline"`)
On ctrl-l we send `\e[2J` (Erase in Display). Some terminals interpret
this to scroll the screen content instead of clearing it. This happens
on VTE-based terminals like gnome-terminal for example.
The traditional behavior of ctrl-l erasing the screen (but not the
rest of the scrollback) is weird because:
1. `ctrl-l` is the easiest and most portable way to push the prompt
to the top (and repaint after glitches I guess). But it's also a
destructive action, truncating scrollback. I use it for scrolling
and am frequently surprised when my scroll back is missing
information.
2. the amount of lines erased depends on the window size.
It would be more intuitive to erase by prompts, or erase the text
in the terminal selection.
Let's use scrolling behavior on all terminals.
The new command could also be named "push-to-scrollback", for
consistency with others. But if we anticipate a want to add other
scrollback-related commands, "scrollback-push" is better.
This causes tests/checks/tmux-history-search.fish to fail; that test
seems pretty broken; M-d (alt-d) is supposed to delete the current
search match but there is a rogue "echo" that is supposed to invalidate
the search match. I'm not sure how that ever worked.
Also, pexepect doesn't seem to support cursor position reporting,
so work around that.

Closes#10934
__fish_cancel_commandline was unused (even before) and has some issues
on multiline commandlines. Make it use the previously active logic.
Closes#10935
When built with the default "installable" feature, the data files (share/) are
included in the fish binary itself.
Run `fish --install` or `fish --install=noconfirm` (for
non-interactive use) to install fish's data files into ~/.local/share/fish/install
To figure out if the data files are out of date, we write the current version
to a file on install, and read it on start.
CMake disables the default features so nothing changes for that, but this allows installing via `cargo install`,
and even making a static binary that you can then just upload and have extract itself.
We set $__fish_help_dir to empty for installable builds, because we do not have
a way to generate html docs (because we need fish_indent for highlighting).
The man pages are found via $__fish_data_dir/man
Mostly we pass on the options - otherwise they would be ignored.
For `clear`, we do need the full checks, because that will
prompt *before* running the builtin.
But this makes it easier to eventually move that logic into the builtin

fish by default shows a git-aware prompt. Recall that on macOS, there are
two hazards we must avoid:
1. The command `/usr/bin/git` is installed by default. This command is not
actually git; instead it's a stub which pops open a dialog proposing to
install Xcode command line tools. Not a good experience.
2. Even after installing these tools, the first run of any `git` or other
command may be quite slow, because it's now a stub which invokes `xcrun`
which needs to populate a cache on a fresh boot. Another bad experience.
We previously attempted to fix this by having `xcrun` print out its cache
path and check if there's a file there. This worked because `xcrun` only
lazily created that file. However, this no longer works: `xcrun` now
eagerly creates the file, and only lazily populates it. Thus we think git
is ready, when it is not.
(This can be reproduced by running `xcrun --kill-cache` and then running
the default fish shell prompt - it will be slow).
Change the fix in the following way: using sh, run `/usr/bin/git --version;
touch /tmp/__fish_git_ready` in the background. Then detect the presence of
/tmp/__fish_git_ready as a mark that git is ready.
Fixes#10535
This is nicer when you use fish over ssh, and that system does not
have a browser. But the system where your terminal is has one, and so
now you can just click the link.
alt-e restores the cursor position received from the editor, moving by
one character at a time. This can be super slow on large commandlines,
even on release builds. Let's fix that by setting the coordinates
directly.
This happens when using alt-e to edit the command buffer,
adding some lines, leaving the cursor at the end
and quitting the editor without saving.
Let's avoid the noisy error that has sort of bad rendering (would
need __fish_echo).
With BSD man, "PAGER=vim man man | cat" hangs because
[man](https://cgit.freebsd.org/src/tree/usr.bin/man/man.sh) wrongly
calls the pager even though stdout is not a terminal.
This hang manifests in places where we call apropos in a subshell,
such as in "complete -Ccar".
Let's work around this I guess. This should really be fixed upstream
because it's a problem in every app that wants to display man pages
but doesn't emulate a complete terminal.
Weirdly, the Apple derivative of man.sh uses WHATISPAGER instead
of MANPAGER.
Closes#10820
Let's provide a sensible default here. Use a line for "insert" and an
underline for "replace_one" mode. Neovim does the same, it feels pretty
slick.
As mentioned in #10806
As of the parent commit, __fish_vi_key_bindings_remove_handlers
should be working properly now, so this is no longer necessary That
function also cleans up other stuff like fish_cursor_end_mode, that
fish_default_key_bindings doesn't know anything about.
Also this fixes a spurious exit status of 4 in some scenarios.
fish_key_bindings may be set directly
or via fish_{default,vi}_key_bindings.
The latter use "set --no-event" to simplify their control
flow. This (24836f965 (Use set --no-event in the key binding
functions, 2023-01-10)) broke Vi mode cleanup, since Vi mode
uses a variable hook. Let's update this variable also when using
fish_{default,vi}_key_bindings. Another reason to keep this variable
in sync is to make the fish_key_bindings handlers working as expected.
This makes the default colorscheme less colorful for two reasons:
1. It makes it a little less "angry fruit salad"
2. Some terminals (like Microsoft's Windows Terminal) have a terrible
blue default that contrasts badly against a black background
The alternative is to make *parameters* "normal" and give commands the
current parameter color (cyan). But I've seen cyan be quite blue and
quite green depending on the terminal, so I don't want to rely on it.
There is no natural default binding for token movements. Add the
alt-{left,right,backspace,delete}, breaking some existing behavior.
For example, backward-delete-word is no longer bound to alt-backspace but
only to ctrl-backspace. Unfortunately some terminals (particularly tmux)
don't support distinguishing ctrl-backspace from ctrl-h yet, so the loss
of alt-backspace may be tragic.
---
I guess we could also add:
bind alt-B backward-token
bind alt-F forward-token
bind ctrl-W backward-kill-token
bind alt-D kill-token
Those might be intercepted by the terminal on Linux, but I don't know where
that happens.
Tested on foot, kitty, alacritty, xterm, tmux, konsole and gnome-terminal.
Closes#10766
Users may install two versions of fish and configure their terminal to run
the one that is second in $PATH. This is not really what I'd do but it
seems reasonable. We should not need $PATH for this.
Fixes#10770
1. Leave the indentation
2. Leave the "NAME" header - without the first line would be
unindented
3. Leave the "SYNOPSIS" header
We use $MANPAGER here, so it should be formatted like a manpage.
The alternative is to write special docs for this use-case, which
would be shorter and point towards the full man page.
Fixes#10625
They are already presented in normal mode, and I presume were forgotten to be
added in visual mode
I don't add it to ./CHANGELOG.rst because it's a minor change that can be
considered as a bug fix
When `manpath` prints a symlink to a directory, `/usr/libexec/makewhatis`
ignores the entire directory:
```
$ /usr/libexec/makewhatis -o /tmp/whatis \
(/usr/bin/manpath | string split :)
makewhatis: /Users/wiggles/.nix-profile/share/man: Not a directory
```
This means that the built-in `man` completions will not index any commands in
these directories.
If we pass the directories to `readlink -f` first, `makewhatis` correctly
indexes the `man` pages.
```
$ /usr/libexec/makewhatis -o /tmp/whatis \
(/usr/bin/manpath | string split : | xargs readlink -f)
```
