A Zsh widget to toggle a prefix on a command
By default, this will set "Alt+s" to toggle sudo on a command.
In its current state, it uses split-shell-arguments to divide up the buffer, and looks for newlines, ;/&&/||/|, followed optionally by if/else/while/etc.
This method should avoid any false positives, but it will also ignore $(command substitutions).
This project also makes use of all sudo flags known by the completion function _sudo and deletes them and their arguments if found as well. For example, sudo -uuser -g group --shell foo bar will be replaced by foo bar, since -u and -g take arguments, while --shell does not.
toggle-sudo Alt-s sudo sudo followed by any number of supported flags known by _sudo completion toggle-noglob Alt-g noglob noglob toggle-nocorrect (not bound) nocorrect nocorrect toggle-command Alt-Shift-c command command
Launch a command with i3-msg instead of in the current session.
.toggle-i3exec(){
.toggle-command-prefix 'i3-msg -- exec -- ' 'i3-msg' '(--|exec)'
}
zle -N .toggle-i3exec
bindkey '^[i' .toggle-i3exec
Launch a command with nice
.toggle-nice(){
.toggle-command-prefix 'nice -n10 ' 'nice' '(-n?|--adjustment=)*' '(-n|--adjustment)'
}
zle -N .toggle-nice
bindkey '^[n' .toggle-nice
Toggle-command-prefix uses zstyle settings to control certain behavior.
If a command is found and removed, the following lookup is done:
zstyle -t :zle:toggle-command-prefix:${removed_text} copy
If the lookup returns true, then the remove text is also yanked into the cut buffer for later pasting.
You can use this like so:
# copy by default zstyle ':zle:toggle-command-prefix:*' copy true # don't copy sudo by itself zstyle ':zle:toggle-command-prefix:sudo ' copy false # copy sudo followed by any number of other matched flags zstyle ':zle:toggle-command-prefix:sudo -*' copy true
