A dynamic menu for the terminal written in pure Bash
Simply direct the items to shmenu's stdin, separated by newlines.

In true suckless fashion, shmenu is configured through its source code. I usually don't prefer this philosophy, but dmenu was meant (as far as I know) to be used through shell scripts, after all; since shmenu itself is written in Bash, you can include the modified shmenu with it. I will still consider it, though.
The only time I used that with dmenu was when I was executing commands, and there isn't really a reason to do that with shmenu as it's run from a terminal.
