Collision window navigation module for AwesomeWM

Warning: The master branch is for Awesome 4.0+, use the awesome3.5 branch for older versions of Awesome.

This module add some visual indicators for common window management operations. It is now easier to know the impact of a given command as a visual queue will be printed on the screen. Collision has 3 modes:

Focus: Move the focus from client to client
Move: Move a client
Resize: Change a client dimensions
Tag: Move to the previous/next tag

Installation

First, clone the repository

    mkdir -p ~/.config/awesome
    cd ~/.config/awesome
    git clone https://github.com/Elv13/collision

Now, open ~/.config/awesome/rc.lua (or copy /etc/xdg/awesome/rc.lua to ~/.config/awesome/rc.lua fist if you never modified your Awesome config before) and add this line somewhere in your rc.lua:

    require("collision")()

It is a very good idea to also change the default Mod4+arrow shortcut to something else:

    --Remove those lines:
    awful.key({ modkey,           }, "Left",   awful.tag.viewprev,
     {description = "view previous", group = "tag"}),
    awful.key({ modkey,           }, "Right",  awful.tag.viewnext,
     {description = "view next", group = "tag"}),

Your done!

Usage

Using Collision is easy. You just have to hit the arrow keys (➡ ⬆ ⬇ ⬅) with some modifiers keys. The Shift key is usually used for grabbing something while the Control key is used to max out the effect.

Modifier 1	Modifier 2	Modifier 3	Effect
`Mod4`			Move the focus on the tiled layer
`Mod4`		`Control`	Move the focus on the floating layer
`Mod4`	`Shift`		Move a client in the tiled or floating layer
`Mod4`	`Shift`	`Control`	Move a floating client to the far side of that screen
`Mod4`	`Mod1 (Alt)`		Increase a floating client size
`Mod4`	`Mod1 (Alt)`	`Shift`	Reduce a floating client size
`Control`	`Mod1 (Alt)`		Move to the next/previous tag
`Control`	`Mod4`	`Mod1 (Alt)`	Move to the next/previous screen
`Control`	`Mod4`	`Mod1 (Alt)`	+ `Shift` Move tag to the next/previous screen

Using different keys

Due to the large ammount of keyboard shortcut Collision create, they are auto-generated automatically. While this make installation simpler, it also make Collision somewhat hard-coded magic. Some alternative keymaps can also be ackward to use because of the reliance on mod keys such as Alt and Control.

That being said, Collision allow some basic remapping. Instead of:

    require("collision")()

This can be used:

    require("collision") {
        --        Normal    Xephyr       Vim      G510
        up    = { "Up"    , "&"        , "k"   , "F15" },
        down  = { "Down"  , "KP_Enter" , "j"   , "F14" },
        left  = { "Left"  , "#"        , "h"   , "F13" },
        right = { "Right" , "\""       , "l"   , "F17" },
    }

Of course, if the Vim keys are used, any other shortcut binded to them have to be removed from rc.lua.
