I'm building a script that pipes the workspace information into bar (bar ain't recursive), with an i3 config and tmux setup that works similarly to tagging. the status bar works well currently, but I'd really like to sex things up and streamline keybinds with scripts. However, the only way I see this is possible is by identifying which windows belong to a workspace, or at least by seeing which windows are visible.Sat, 22 Jun 2013 16:49:30 +0000https://faq.i3wm.org/question/2066/how-to-find-out-which-windows-are-currently-visible-or-which-workspace-they-belong-to/https://faq.i3wm.org/question/2066/how-to-find-out-which-windows-are-currently-visible-or-which-workspace-they-belong-to/?answer=2070#post-id-2070You can use `i3-msg -t get_tree` to dump the JSON whole tree of your existing workspaces / windows. The amount of data is quite big so you'll need to parse it to extract the data you want. Either implement your own or use a binding that simplifies the job, e.g in Python, github.com/ziberna/i3-py. Example: import i3 # get a list of workspaces for workspace in i3.get_workspaces(): # get the workspace tree data workspace_tree = i3.filter(num=workspace.get('num')) # get a list of existing leaf windows in that workspace for window in i3.filter(workspace_tree, nodes=[]): # do something useful here print 'workspace %d' % workspace.get('num'), 'window:', window.get('name') This would output such thing: workspace 1 window: duplicity-backup - Runs duplicity for backups to FTP workspace 1 window: man duplicity workspace 3 window: How to find out which windows are currently visible? or which workspace they belong to - i3 FAQ - Mozilla Firefox workspace 3 window: ipython workspace 9 window: Quassel IRC workspace 10 window: newsbeuter workspace 10 window: ncmpcpp workspace 10 window: htop The `window` dictionary in the python snippet contains useful stuff like that: fullscreen_mode, orientation, focus, urgent, last_split_layout, floating, border, id, current_border_width, layout, percent, workspace_layout, window, nodes, type, swallows, focused, scratchpad_state, rect, window_rect, name, geometry, floating_nodesSun, 23 Jun 2013 13:22:20 +0000https://faq.i3wm.org/question/2066/how-to-find-out-which-windows-are-currently-visible-or-which-workspace-they-belong-to/?answer=2070#post-id-2070
