Collision window navigation module for AwesomeWM

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:

    --Change
    awful.key({ modkey,           }, "Left",   awful.tag.viewprev       ),
    awful.key({ modkey,           }, "Right",  awful.tag.viewnext       ),

    --To:
    --awful.key({ modkey,           }, "Left",   awful.tag.viewprev       ),
    --awful.key({ modkey,           }, "Right",  awful.tag.viewnext       ),

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 om 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)		Resize a client relative to the bottom right corner
Mod4	Mod1 (Alt)	Shift	Resize a client relative to the top left corner
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.

Settings

-- Swap clients across screen instead of adding them to the other tag
collision.settings.swap_across_screen = true

Other

The collision.select_screen(idx) function allow to select a screen and can be assigned to shortcuts.

The collision.highlight_cursor(timeout) method will highlight the current mouse cursor position.

Notes

Using the focus arrows to select empty screens only work in Awesome 3.5.7+
