I'd like to use Dzen2 instead of i3bar. I'm comfortable with using i3-msg to display workspace information on a Dzen2 instance, but I'd also like to display the title of the active window.

I understand that the window title information is contained in the JSON dump returned by running "i3-msg -t get_tree", but I'm not sure of a reliable way to retrieve the title of the active window from this dump. I'm thinking I'll use a python script to do it, but I don't understand the structure of the i3 tree well enough.

Any guidance on how to retrieve this information is much appreciated.

You could use xdotool, which can be found in many distribution repositories. The NETWM_NAME property of the currently focused window can be grabbed with

xdotool getwindowname $(xdotool getwindowfocus)

Otherwise you'd need to write a script to parse the JSON tree output.

I had to run `xdotool getwindowfocus | xargs xdotool getwindowname`, which works great. Thanks for pointing me at xdotool.

I didn't consider that my line works in Bash/Zsh, and not necessarily any other shells. :P Good to see you got it working.

You also can use `xdotool getwindowfocus getwindowname`. This utilizes the command chaining feature of `xdotool`. You could also use `getactivewindow` instead of `getwindowfocus` as the man page states that it may be more reliable.
