Can't bind C-z to a readline function without getting 'readline: maximum macro execution nesting level exceeded' with fzf-cd - Alt-C about fzf HOT 5 OPEN

I forgot a relevant line. Also set this in your .bashrc (bash --noprofile --rcfile <(fzf --bash) isn't completely similar):

[ -f ~/.fzf.bash ] && source ~/.fzf.bash

# Unset suspend signal shortcut (Ctrl+z)
stty susp undef

bind -m emacs-standard  '"\C-z": vi-undo'
bind -m vi-command      '"\C-z": vi-undo'
bind -m vi-insert       '"\C-z": vi-undo' 

in your .bashrc gives the 'readline: maximum macro execution nesting level exceeded' when using Alt-C

Sourcing [ -f ~/.fzf.bash ] && source ~/.fzf.bash after these lines will fix this mostly

# Unset suspend signal shortcut (Ctrl+z)
stty susp undef

bind -m emacs-standard  '"\C-z": vi-undo'
bind -m vi-command      '"\C-z": vi-undo'
bind -m vi-insert       '"\C-z": vi-undo' 

[ -f ~/.fzf.bash ] && source ~/.fzf.bash

Now Alt-C works, but Ctrl-z will now be bound to changing editing-modes (vi/emacs).
Removing stty susp undef stops this behaviour but also breaks `vi-undo

from fzf.

Found out that it can only be reproduced in vi mode (which I don't use).

$ bash --noprofile --rcfile <(fzf --bash)
bash-5.2$ bind -m emacs-standard  '"\C-z": vi-undo'
bind -m vi-command      '"\C-z": vi-undo'
bind -m vi-insert       '"\C-z": vi-undo'
bash-5.2$
bash-5.2$ set -o vi
bash-5.2$ readline: maximum macro execution nesting level exceeded

So the current implementation relies on its internal C-Z binding, and overriding it breaks it. Patches are welcome.

from fzf.

Upon further inspection it seems like it had something to do with the order that i sourced my ~/.bashrc files more then a fzf bug.

First readline (bind) keybinds, then fzf, then 'complete -F _complete_alias "${!BASH_ALIASES[@]}"'

EDIT: Nevermind, it still seems to be a pure fzf issue and only comes up if I bind Ctrl-Z to something after sourceing ~/.fzf.bash

from fzf.

Can't reproduce.

bash --noprofile --rcfile <(fzf --bash)

bind -m emacs-standard  '"\C-z": vi-undo'
bind -m vi-command      '"\C-z": vi-undo'
bind -m vi-insert       '"\C-z": vi-undo'

from fzf.

I'm having the exact same issue.
