awesome-handy - Popup programs for awesomewm

handy is a module for awesome, that allows you to open and hide a floating program with a keybinding. Main features:

• spawns an instance per screen or can be bound for a specific screen
• instances are remembered across awesome restarts, so pressing your key won't start a second instance but reuse the previous one
• placement via awful.placement API

handy requires awesome 4.0+

Installation

Put this repository somewhere in the lua search path for awesome. If you're using LuaRocks, you can install it via

luarocks install --local awesome-handy

Alternatively, if your awesome configuration is managed by git, you can add this repo as a git submodule:

git submodule add https://github.com/crater2150/awesome-handy.git handy

Otherwise just clone it into your configuration directory.

Then, in your rc.lua:

local handy = require("handy")

Usage

The following example spawns an urxvt instance in the center of the screen, 90% wide and 70% high when pressing F12 the first time, after that it toggles its visibility:

awful.key({ }, "F12", function ()
	handy("urxvt", awful.placement.centered, 0.9, 0.7)
end ),

The following parameters are accepted:
handy(prog, placement, width, height, options, screen, class)

• prog: the only mandatory parameter, the command to run

• placement: controls the position of the window, see awful.placement

• width, height: the size of the program. Values ≤ 1 are interpreted as percentage of screen size, values above 1 are interpreted as pixel sizes

• options: arguments passed to awful.placement

• screen: the screen to use. if not given, defaults to the currently focused screen, so each screen will have its own instance

  You can also set this to the string "single" for a client, that should only have a single instance (instead of one per screen). The client will always be shown on the currently focused screen, even if it was opened on another screen before (note that if the client is currently shown on an unfocused screen, you'll have to toggle it twice to move it to the current screen).

• class: If given, must be the class or instance name of the window. Will enable using the fallback method for programs not supporting startup notification (see below)

Programs without startup notification

The default method for handy to detect which window is supposed to toggle is to use awful.spawn with a callback. This callback mechanism works by passing a startup id to the program, which only works with programs supporting the Startup Notification spec.

When specifying the window instance name, handy will use a fallback method for the callback, which has the drawback, that if you start another program with the same class/instance during the startup of the first, the one which displays its window earlier will become the pop-up. If your program supports it, use a custom window instance that is unlikely to be used by other windows (e.g. "handy" + program name) and don't double press the key for handy.
