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.
