Implementation of Blezzing - blezz in pure Bash (4+ should be fine).

Given a blezz-formatted file, it'll allow you to launch programs or start tasks by pressing a button or sequence of buttons. Should be compatible with Blezz files, and rofi-blezz as well.

I started using Blezz files to define launchers and I find it very convenient, specially as a Rofi plugin. I wanted something compatible with the same files for the console, and I thought that if I'm in a situation where I can't use Rofi, I'd probably be in some limited environment through SSH. So I made it as minimal as possible using only a modern-ish version of Bash (considered AWK, but bash is common enough!)

directoryName:

Defines the contents of a directory. It's similar to a "goto" label. Anything before a label will be top level.

dir(key, dirName)

When pressing key it'll open the defined directory.

act(key, label, action)

When pressing key it'll start the defined action. Use sh-compatible syntax.

# Comment

Lines starting with a # will be commented out.

Any key you can type on your keyboard should work for the value of key, I've tested it with non-US characters, capitals and such without issue.

# This is a sample blezz file, and a comment.
dir(1, test)
act(2, Firefox, firefox)

test:
act(1, libreoffice)

Will let you press "2" to launch firefox, and "1, 1" to open libreoffice.

. to go back to a previous folder, or close the application if at top level. You may also quit with Escape and Ctrl+C. Any assigned key will perform its given action, and non-assigned keys should show an alert.
