* 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)
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.
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.
Some of the completions recently introduced called Blender itself to query some
arguments, and Blender sometimes prints messages to stderr. This output was not
filtered, resulting in the shell printing irrelevant messages during completion.
- Replace short options with old-style options: even though they are
single-letter, Blender's options cannot be combined.
- Add comments to separate blocks of options, mirroring Blender's help message.
- Add missing options: render-frame, python-use-system-env, register-allusers,
unregister, unregister-allusers.
- Remove options: debug-gpu-disable-ssbo, debug-gpu-renderdoc, -R.
- Fix typos:
- debug-depsgraph-eval (was -evel)
- debug-depsgraph-pretty (was -time)
- app-template (was open-last)
- Update output formats:
- Add descriptions.
- Add HDR, TIFF, OpenEXR, OpenEXR Multilayer, FFmpeg, Cineon, DPX, JPEG 2000,
and WebP, which are optional but generally available.
- Remove IRIZ, which is no longer available.
- Fix arguments for --use-extension: they should be 0 or 1, not true or false.
- Make env-system-* options require a parameter.
- Improve --add-ons by querying the list of add-ons inside Blender rather than a
hardcoded path. This is because Blender's add-on modules may come from many
different paths which depend on platform.
- Fix __blender_echo_input_file_name, by relying on extension.
- Fix listing of scene datablocks inside Blend file.
- Add listing of Python text datablocks to execute inside Blend file.
Closes#10150
