I want to have a TMUX session in my Scratchpad, automatically executed on startup. So far, I' using a setup without TMUX like this: exec --no-startup-id urxvt -name Scratch -e ranger for_window[class="URxvt" instance="Scratch"] move window to scratchpad, border 1pixel This is working just fine. What I want to have is something like that: exec 'urxvt -name Scratch -e tmux new-session -s Scratch -n FM ranger' exec --no-startup-id 'tmux new-window -n Cal wyrd' exec --no-startup-id 'tmux new-window -n Music ncmpcpp' This, however doesn't work. Either a scratchpad is initiated nor a TMUX session. If I am sending the above commands via 'i3-msg', it does work, which I find rather disturbing. Any ideas anyone? Meanwhile I can start up a tmux session using this function in my config.fish: function scratch tmux attach -t Scratch or begin tmux new-session -s Scratch -d -n Music ncmpcpp and tmux new-window -n Files ranger and tmux new-window -n Cal wyrd and tmux new-window -n Todo vit and tmux selectw -t 1 and tmux attach-session -d end end which is invoked by my i3.conf via exec --no-startup-id urxvt -name Scratch -e fish -c scratch But it is not handled by the hook for_window[class="URxvt" instance="^Scratch"] move window to scratchpad, border 1pixelMon, 08 Jun 2015 14:41:11 +0000https://faq.i3wm.org/question/6090/tmux-in-scratchpad-solved/https://faq.i3wm.org/question/6090/tmux-in-scratchpad-solved/?comment=6093#comment-6093Can you confirm that class and instance are set correctly on the urxvt window in your workaround?Tue, 09 Jun 2015 05:53:28 +0000https://faq.i3wm.org/question/6090/tmux-in-scratchpad-solved/?comment=6093#comment-6093https://faq.i3wm.org/question/6090/tmux-in-scratchpad-solved/?answer=6098#post-id-6098Hi, thank you for your replies. The output of xprop for my scratchpad is: WM_CLASS(String) = "urxvt", "URxvt" WM_NAME(STRING) = "Scratch:1:Files - <hostname>" The compound WM_Name was the reason why I used "^Scratch" in the for_window class.

Answers should always answer the original question. That said, it seems that the instance is 'urxvt' instead of 'Scratch'. If you want to match the title, you need `[title="...."]`.Wed, 10 Jun 2015 08:11:48 +0000https://faq.i3wm.org/question/6090/tmux-in-scratchpad-solved/?comment=6102#comment-6102https://faq.i3wm.org/question/6090/tmux-in-scratchpad-solved/?answer=6097#post-id-6097 The reason your first extended setup for `tmux` does not work is twofold: 1. *i3* uses only double quotes for quoting. That means any single quotes are not interpreted by *i3* (config or `i3-msg`) in any way. So if you write exec 'urxvt -name Scratch -e tmux new-session -s Scratch -n FM ranger' in your configuration, i3 will not remove the single quotes and tries to run the command with the name`'urxvt -name Scratch -e tmux new-session -s Scratch -n FM ranger'` instead of `urxvt` with the rest as arguments. Either do not quote (as in your first example) or use double quotes. 2. Even with correct quoting it is not guaranteed that the *URxvt* window and the contained *tmux* instance are up and running when the `tmux new-window` commands are run as *i3* just executes the commands as soon as it encounters them in the configuration without waiting in between. ---- Your current solution with offloading all *tmux* related stuff into a script or function and then only running *URxvt* (with the script or function as argument) directly from the *i3* configuration is exactly how I would solve this issue. And from what you posted there should be no reason why it should not work with the `for_window` configuration. Here are a few things you can try to debug this: - use `"Scratch"` instead of `"^Scratch"` as it seemed to work in your initial example, although both should be fine. - check the class and instance of the *URxvt* window with `xprop` (or similar), if they indeed match "URxvt" and "Scratch". - try if the hook works if you replace `fish -c scratch` with another command, for example `sh` or `ranger` as before. - maybe try to replace the *fish* function with a simple *sh* script.
