application switcher?

asked 2013-03-02 16:35:59 +0000

I find my self lost among all workspaces and application windows. Is there an application switcher that can be used with i3? Or is there a way to get something similar. All I want is a list of the active application widows which I can tab through to switch to the window i want to go to next.

TIA

Albert

Not sure if this isn't a duplicate of my question: https://faq.i3wm.org/question/228/how...

Anyway, the i3-py solution there works great for me.

neat... but neither this nor the simpleswitcher can grab a window from scratchpad... (not sure how should be the behaviour though)... they are in the list, but nothing happens.

Parsing JSON in shell is really fugly and fragile. I recommend not using this solution (or any other shell solution).

I reworked Rasi solution to avoid python and bash, it behaves exactly the same but with less dependencies (dmenu and sh)

I'm using a ruby script, with this map:

bindsym $mod+g exec ~/.i3/window-jump

The advantages of this script are that it only requires dmenu, finds windows in the scratch space, and focuses by unique ID rather than title.

#!/usr/bin/ruby
require 'json'

# recursively walk tree to find all containers
# return an array of names followed by [id]
def get_containers tree
    containers = []
    # try to return only useful containers
    if (tree['nodes']+tree['floating_nodes']).empty? && tree['type'] == 2 &&
        !(tree['name'] =~ /^i3bar for output/)
        containers << tree['name'] + " [#{tree['id']}]"
    end
    (tree['nodes'] + tree['floating_nodes']).each do |node|
        containers += get_containers(node)
    end
    containers
end

IO.popen(['dmenu', '-i', '-p', 'window jump'], 'r+') do |dmenu|
    dmenu.puts(get_containers(JSON.load(`i3-msg -t get_tree`)))
    dmenu.close_write
    id = dmenu.read.split(/\[|\]/).last
    exec "i3-msg [con_id=#{id}] focus"
end

thanks for your reply. I'll maybe try that approach as well in the near future.

I use quickswitch (or the original one in python: quickswitch.py).

There is also a more fancy version: simpleswitcher

thanks for that one, I settled with quickswitch.py it works as expected.

quickswitch works well, but does anyone know how to enlarge its font?

@oldos2er: It simply uses dmenu, with the python version you can specify the command using the `-d` (or `--dmenu`) switch to quickswitch.py, my ruby version has the command hardcoded in the source.
