A fish shell plugin to use fzf to insert items from the killring into the current command line
Fish uses an Emacs-style kill ring with (by default) ctrl+y and alt+y.
It's very simple to use if it has only a few short, non-overlapping entries – otherwise it can get a bit unwieldy, though.
For those cases, this plugin is useful. Use your favoured binding to invoke fzf in multi-mode and choose one or more entries from the killring, which will be inserted at the current cursor position in the selected order, and separated by whitespace.
Needs fzf and fish v.3.3 or newer because it uses the new $fish_killring variable.
fisher install bagohart/fzf-killring.fish
Copy the file _fzf_select_from_killring.fish into $XDG_CONFIG_HOME/fish/functions/ (probably ~/.config/fish/functions).
This plugin uses fzf with the --multi switch. No other fzf settings are configured, and your settings in FZF_DEFAULT_OPTS are honored.
You can set $fzf_killring_opts to add fzf settings for only this plugin.
Note that $fzf_killring_opts is appended last, so it overwrites earlier settings from FZF_DEFAULT_OPTS.
You can even use it to overwrite the --multi switch.
No bindings are added by installing the plugin, so add a suitable binding to your config.fish. I use ctrl+alt+k:
bind \e\ck _fzf_select_from_killring
Use fish_key_reader and press a key to find out the corresponding code.
Use bind <code> to discover if it's already bound to something else.
For more information, read the docs.
Using this plugin together with fzf.fish
fzf.fish is a great plugin.
Its author isn't interested in adding this feature to it though, so I decided to publish this as a standalone plugin.
There should be no problem in using both plugins (I do!). If there ever is a conflict, please file a bug report!
