* Update just.fish to handle descriptions for completions
This change updates fish completions to also include descriptions for justfile recipes. It has been tested with descriptions for recipes with arguments as well
* rely on fish only (avoid sed)
Version 2.1.0 introduced subsequence matching for completions but as the
changelog entry mentions, "This feature [...] is not yet implemented for
options (like ``--foobar``)". Add it. Seems like a strict improvement,
pretty much.
.unwrap() is in effect an assert(). If it is applied mistakenly, the
program crashes and there isn't a good error.
I would like it to be used as a last resort. In these cases there are
nicer ways to do it that handle a missing result properly.
Fix cases like
eval my-cmd (commandline -o)
complete -C "my-cmd $(commandline -o)"
In both cases, we spuriously evaluate tokens like "(inside-quoted-string)"
as command substitutions. Fix this by escaping the strings. The momentarily
regresses the intended purpose of "eval" -- to expand variables -- but the
next commit will fix that.
Issue #10194 reports Cobra completions do
set -l args (commandline -opc)
eval $args[1] __complete $args[2..] (commandline -ct | string escape)
The intent behind "eval" is to expand variables and tildes in "$args".
Fair enough. Several of our own completions do the same, see the next commit.
The problem with "commandline -o" + "eval" is that the former already
removes quotes that are relevant for "eval". This becomes a problem if $args
contains quoted () or {}, for example this command will wrongly execute a
command substituion:
git --work-tree='(launch-missiles)' <TAB>
It is possible to escape the string the tokens before running eval, but
then there will be no expansion of variables etc. The problem is that
"commandline -o" only unescapes tokens so they end up in a weird state
somewhere in-between what the user typed and the expanded version.
Remove the need for "eval" by introducing "commandline -x" which expands
things like variables and braces. This enables custom completion scripts to
be aware of shell variables without eval, see the added test for completions
to "make -C $var/some/dir ".
This means that essentially all third party scripts should migrate from
"commandline -o" to "commandline -x". For example
set -l tokens
if commandline -x >/dev/null 2>&1
set tokens (commandline -xpc)
else
set tokens (commandline -opc)
end
Since this is mainly used for completions, the expansion skips command
substitutions. They are passed through as-is (instead of cancelling or
expanding to nothing) to make custom completion scripts work reasonably well
in the common case. Of course there are cases where we would want to expand
command substitutions here, so I'm not sure.
Move all qmark tests to `scoped_test()` sections with explicitly set feature
flags. We already test the default qmark behavior in the functionality tests.
This prefers `-s` to `-v` - we have a *lot* more uses of `command -s`, it's the easier
mnemonic *and* the more compatible-with-fish option.
Also we don't really need the separate section that explains what
these options do *again*.
It seems the logic for calculating the cursor position was not ported correctly,
because the correct place to insert it is at the cursor_pos regardless of
range.start, going by the parameters submitted to the function and the expected
result.
This allows running a fish built from `cargo build` *and* built via
cmake.
In future, we should make this an optional thing that's removed from
installed builds.
This is our traditional behavior; "man" and "git" do the same.
(cherry picked from commit b83f3b0e98)
Proposing this for 3.7.1 because I think see this as regression in 3.7.0 -
a user might have installed bat for syntax highlighting only.
We're already moving them, we can remove the awkward dot that hides
them, and while we're doing that remove the useless $USER as well.
Most systems will have only one of these files - it's rare to run a
second package manager (especially for anything more than
bootstrapping a container).
These take a *lot* of time - `pip3` takes 180ms, `pipenv` takes 320ms
on my system.
Note that this removes a number of obsolete workarounds - pip's was
fixed in 2017 (and pip2 is less and less of a thing), pipenv's change
was in 2019.
Since these are packaging tools with access to the internet they
should really be kept up-to-date, so it is unlikely someone still uses
these old versions.
We have a lot of completions that look like
```fish
pip completion --fish 2>/dev/null | source
```
That's *fine*, upstream gives us some support.
However, the scripts they provide change very rarely, usually not even
every release, and so running them again for every shell is extremely
wasteful.
In particular the python tools are very slow, `pip completion --fish`
takes about 180ms on my system with a hot cache, which is quite
noticeable.
So what we do is we run them once, store them in a file in our cache
directory, and then serve from that.
We store the mtime of the command we ran, and compare against that for
future runs. If the mtime differs - so if the command was up or
downgraded, we run it again.
