A plugin for Oh My Fish.
$ omf install underbarThe installation also attempts to add following key sequences.
- bind \eg underbar #alt+g
- bind \ei underbar_paste #alt+i
This plugin wraps a command so the contents of stdout will be captured into a dedicated variable, named underbar.
It is supposed to work with a custom key binding(default is alt+g).
For example:
# bind alt+g
$ bind \eg underbar
# type a command in command line, then press alt+g to let the function wraps your command.
$ echo 'foo
bar'
# will become
$ set -g underbar (echo 'foo
bar')
# then the content of stdout is kept in the global variable `underbar' after execution, and you can manipulate it like any other fish variables,
# or inspect.
$ set --show underbar$underbar: set in global scope, unexported, with 2 elements
$underbar[1]: |foo|
$underbar[2]: |bar|
By pressing the binding key again, the wrap is toggle-off.
underbar_paste(default bind to alt+i)
This function allows user to select one of items the $underbar variable contains to insert into current command line to complete.
If fzf is available, items can be filtered out.
Without fzf, it will show items in cdh style.
underbar_show
It inspects the variable.
As it will repaint the command line after showing information, by binding to a key , it will tell you what is saved in the $underbar as typing commands with no distraction.
# bind alt+i
$ bind \ei underbar_show
# then press alt+i, `set --show underbar` is executed
