Add option to Interact with selection

[AhmedAbdulrahman]

I would like to thank you for this awesome plugin :).

I have extended stash functionality to add options to interact with selections using pop, apply or evencheckout to selection.

bindings:

• CTRL + b checks out the stash as a branch and removes the stash `
• CTRL + y will apply the stash`
• CTRL + x will drop the stash`

I would appreciate if you reivew it

Hi @AhmedAbdulrahman Thanks for your contribution!

This feature looks great. But it doesn't seem to work properly under bash:

bash: ${(f)out}: bad substitution

Since the forgit.plugin.sh is a soft link to forgit.plugin.zsh we should ensure the compatibility.

Another problem is the keybinding conflict. ctrl - b is a universal keybind to move backward one character. ctrl - y is used for copy selection already. It's hard to find some keybinds which are meaningful and not occupied.

I think we should separate these actions into three different functions named gsc/forgit::stash::checkout, gsa/forgit::stash::apply and gsd/forgit::stash::drop so that we can use fewer keybinds and keep the code simple enough for compatibility & maintainability.

The latest fzf add support for reloading input without exiting: junegunn/fzf#1750

Now to implement this feature you only need to add a bind to FORGIT_STASH_FZF_OPTS like this:

FORGIT_STASH_FZF_OPTS='
--bind="ctrl-x:reload(git stash drop $(cut -d: -f1 <<<{}) 1>/dev/null && git stash list)"
'

Considering the existing interfaces already support adding keybind I decided to put it as an example in the readme instead of adding a lot of new commands.
