hyprctl: Add shell completions

[LOSEARDES77]

Describe your PR, what does it fix/add?

Add shell completions for bash and fish for the hyprctl command

Is there anything you want to mention? (unchecked code, possible bugs, found problems, breaking compatibility, etc.)

Have only tested in bash and fish shell

Is it ready for merging, or does it need work?

Its still WIP
Its my first time experimenting with completions so i don`t know if this is the correct way of doing it but this just works for me

Fish:

Bash:

It would appear that this disregards nesting. It just gives the completion on the first level.

hyprctl dispatch clients
activewindow getoption output version
activeworkspace globalshortcuts plugin workspacerules
binds hyprpaper reload workspaces
clients instances rollinglog -j
configerrors keyword setcursor -r
cursorpos kill seterror --batch
decorations layers setprop --help
devices layouts splash --instance
dismissnotify monitors switchxkblayout
dispatch notify systeminfo

i see what you mean,
I'll make it work i progress

I think its ready for revision

[LOSEARDES77]

There is a issue when doing sudo make install the ~ is /root, ${HOME} is /root and ${USER} is root too.
Because of this the completions files source to the root user.
I don't know how to address this

[fufexan]

Sourcing shouldn't be necessary. Shells will automatically load the completions from their default directories.

[fufexan]

Tested functionality in all the shells and it seems to be working fine.

I've also added the install instructions to meson.

LGTM. Thanks for the contribution!

[bvr-yr]

this supposed to be <KEYBOARDS> ?

[fufexan]

Looks like it. I'll push a fix.

[bvr-yr]

it also means that actual <KEYWORDS> array is missing, referenced on line 71

[fufexan]

I was too hasty in merging this.

@LOSEARDES77 it looks like the KEYWORDS definition does not exist. Were you planning on adding it?

[LOSEARDES77]

I forgot to add the keywords

[LOSEARDES77]

I'll work on hyprpm completions today and add the missing keywords

[LOSEARDES77]

Can't find a way to retrieve aviable keywords

https://github.com/scop/bash-completion/blob/master/README.md
bash completions should be installed in

❯ pkg-config --variable=completionsdir bash-completion
/usr/share/bash-completion/completions

for fish:
from https://fishshell.com/docs/current/completions.html:

A directory for third-party software vendors to ship their own completions for their software, usually /usr/share/fish/vendor_completions.d;

[LOSEARDES77]

I see ill applt suggested changes to #5423

[Ordoviz]

This could be improved a little further by taking inspiration from #3535

[fufexan]

@Ordoviz I completely missed that PR, apologies. Can you rebase it and make whatever changes you see fit?
