Building
To build il(hare) you must first install hare, hare-libtui and hare-ev then run:
hare build -o il .
Usage
To run il, simply pass a list of items to il's stdin:
ls | il
This will allow you to select items from the list using j and k, mark items using the spacebar and print them to stdout and exit using enter or l. The currently selected item is also the marked item if none have been marked with space. To quit without printing press q. To see other keybindings, refer to handlers.ha.
Examples
This program can be used to allow you to choose items in order to pass them to another command.
For instance:
process killer:
ps aux | il | awk '{print $1}' | xargs kill
file chooser (this example displays information about the files using file), note that il supports a -0 flag that prints NULL separated items instead of the default whitespace separated which is useful for items that contain spaces:
ls | il -0 | xargs -0 file
A launcher for a feed of urls (for instance from an rss feed reader):
feeds.txt with the following contents:
yt_channelname | Video Title: https://www.youtube.com/watch?v=0dKrUE_O0VE
peertube_channel | Insert title here: https://spacepub.space/w/1MnYGVguhGM7tuq2DUKtYQ
...
Then launch:
il < feeds.txt | awk '{print $NF}' | xargs mpv
