Dynamic tagging configuration system for awesomeWM

Tyrannical - A simple rule engine

Description

Shifty was great and served us well since the early days of the Awesome 3.* series, but just as many kid aged TV stars, it havn't grown that well. Many of it's, once unique, features are now supported by the default awful.tag engine, adding legacy complexity to the code base and affecting performance.

This is why Tyrannical was created. It is a light rule engine offering pretty much the same rules configuration, but without all the dynamic tag code. Note that dynamic tagging is now supported directly by awesome.

Examples

Install Xephyr and run the following script

sh utils/xephyr.sh start

Note: The tyranical repository must be named awesome-tyranical for the script to work out of the box.

Also see samples.rc.lua for a sample.

Configuration

If you once used Shifty, you will feel confortable with Tyrannical. The only different is that Tyrannical integrate class matching directly in the tag configuration section. More advanced rules can be created using awful.rules. Again, Tyrannical was not created to duplicate awful, but to make dynamic (and static, as a side effect) tagging configuration easier. This module doesn't require any major initialisation, compared to shifty, it is much more transparent.

The first modification is to include the module at the top of rc.lua:

local tyrannical = require("tyrannical")

Then this section have to be replaced:

-- {{{ Tags
-- Define a tag table which hold all screen tags.
tags = {}
for s = 1, screen.count() do
    -- Each screen has its own tag table.
    tags[s] = awful.tag({ 1, 2, 3, 4, 5, 6, 7, 8, 9 }, s, layouts[1])
end
-- }}}

by:

tyrannical.tags = {
    {
        name        = "Term",                 -- Call the tag "Term"
        init        = true,                   -- Load the tag on startup
        exclusive   = true,                   -- Refuse any other type of clients (by classes)
        screen      = {1,2},                  -- Create this tag on screen 1 and screen 2
        layout      = awful.layout.suit.tile, -- Use the tile layout
        class       = { --Accept the following classes, refuse everything else (because of "exclusive=true")
