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)
```
We keep having to extend these with new terminals, and I can no longer
find a terminal that fails this.
Even emacs' ansi-term can now at least reliably ignore the sequence.
The \e\e\[A style is bad but iTerm and putty (alt-left) use it.
The main motivation for this change is to improve fish_key_reader output.
Part of #10663
Both are plenty fast enough, but this way the output of fish_trace isn't
completely taken over by the loops (seems fair since fish_trace probably gets
used rather heavily for completions).
Part of #1842
The implementation is obviously isn't 100% vi compatible, but works good enough
for major cases
This commit depends on previous commits where jump-{to, till}-matching-bracket

One issue with fish_add_path at the moment is that it is sometimes a bit too intransparent.
You'll try to add a path, but it won't appear - was that because it wasn't a directory,
or because it doesn't exist, or because it was already included?
If it isn't usable after, did fish_add_path not add it because of something or did something *else* remove it?
So we give more explanations - "skipping this because it's a file", "not setting anything because no paths are left to add", ...
fish_add_path can be used either interactively, in the commandline,
or in config.fish. That's its greatest strength, it's a very
DWIM-style command.
One of the compromises that entails, however, is that it can't really
be very loud about what it does. If it skips a path, it can't write a
warning because it might be used in config.fish.
But it *can* if it's used interactively. So we try to detect that case
and enable verbose mode automatically.
That means if you do
```fish
fish_add_path /opt/mytool/bin/mytool
```
it may tell you "Skipping path because it is a file instead of a
directory:".
The check isn't perfect, it goes through status current-command and
isatty, but it should be good for most cases (and be false in config.fish).
Don't fork/exec an external process, especially one performing IO, if we don't
have to.
This, in turn, speeds up __fish_source_cached_completions which is rather slow
under WSL (and slower than it needs to be on other platforms).
We don't set this variable ourselves, but some might set it in their config out
of habit coming from shells that don't automatically colorize ls output.
This variable overrides stdout tty detection for `ls --color=auto` (but does not
modify the behavior of `ls --color=never` or `ls --color=always` regardless of
its value) under at least the BSD version of `ls`. (Under the GNU version, it
influences colorization only if stdout *is* a tty.)
If we detect CLICOLOR_FORCE *and* we are not writing directly to the tty, we
skip colorization (by clearing-but-not-erasing `$__fish_ls_color_opt`, so that
we don't end up accidentally using its value from another scope).
c0bcd817ba removed some key bindings, including the bindings of
ESC ESC [ C for Alt-Right. the commit claimed that
"Sequences like \e\eOC are Escape followed by an SS3 arrow key which we
can already decode separately." but for whatever reason this doesn't work:
Alt-Right is broken in iTerm2 by default.
Restore the default ESC ESC [ X bindings for iTerm2 compatibility.
I've been needing this for some time to generate completions for functions that
we can dynamically generate completions for that take one or more
comma-separated values in any order.
