~/.config/envi/config.yml.

This sample config defines a 'music' and 'dev' space that each start a few applications. Arguments can be passed in brackets: [args, ...]. Using ; as a delimiter, you can tell envi to do something immediately after opening the application. See the subl example below.

music: pithos: height: 650 width: 350 x: 75 y: 75 rhythmbox: height: 650 width: 1024 x: 800 y: 75 dev: subl[; notify-send "It's so sublime"; sh /some/script.sh]: height: 1567 width: 1748 x: 75 y: 68 firefox[--new-tab localhost:8000/ --devtools]: height: 1567 width: 1994 x: 1833 y: 68 nautilus: adjust: true height: 550 width: 1251 x: 1067 y: 1630 gnome-terminal: height: 477 width: 1010 x: 2817 y: 1645 gnome-terminal*: height: 477 width: 1010 x: 1817 y: 1645 gnome-terminal**: height: 477 width: 1010 x: 0 y: 1645

In order of importance:

• Applications can have any number of arguments.
• Safely wait until an application has opened successfully: do we have a new WINID yet? If not, don't proceed. If yes, the application must have opened. This would remove the need for the global startup delay timer.
• Introduce capture command to dump details of focused window (x, y, w, h): envi capture <float>.
• Use wmctrl to switch between workspaces if a space is defined as being on anything other than the current one.
• More than one application with the same name. I might need to bootstrap the YAML loader.
  • Workaround: In the config, place asterisks after the application name. The YAML loader doesn't count these as duplicates and therefore preserves them in the data it returns.
• Verbose output with envi space {spacename} -v |--verbose.
• Look into output of wmctrl -l [-p -x]. Might be able to remove xdotool dependency entirely if this gives me everything I need. Example and explaination
