Feature request

Support fzf init <shell> initialization (like in starship, zoxide, navi etc) to facilitate fzf integration with other tools (file managers, utilities etc) because this style of initialization doesn't require knowledge about key-bindings and completion file paths (which can vary in different packages), fzf will generate apropriate files by itself. Such an approach also cleans up shell rc files. Instead of:

source /usr/share/fzf/completion.bash
source /usr/share/fzf/key-bindings.bash

only one line of code is required:

eval "$(fzf init bash)"

For backward compatibility reasons, the feature implementation can just output existing key-bindings and completion files to stdout. completion and keybindings parameters can be supported to get completion.<shell> or key-bindings.<shell> implementations separately:

eval "$(fzf init bash completion)"
eval "$(fzf init bash keybindings)"

Hasn’t this been actually accomplished in https://github.com/junegunn/fzf/tree/0.48.0 with fzf --bash command?

And related question: what is the purpose of these files in shell/ directory at all? I am a package maintainer of fzf at OpenSUSE, and I got now into a discussion with the people on ble.sh discussions about improper location of these scripts in OpenSUSE. Shouldn’t I just get rid of those sub-packages completely and tell users just to eval appropriate output of fzf subcommands?

Let me leave a comment for cross reference. I've partially answered to the questions in akinomyoga/ble.sh#441 (reply in thread).

Yes, I guess this issue can be closed now.
