Only show normal border when remote shell

Wed, 21 Nov 2012 14:21:54 +0000

I generally use the 1pixel border to save screen space. I would like to show a normal bar only on windows containing a urxvt that shows a remote shell and on all local terminals the default 1pixel border. While this works (1pixel border as default and normal as soon as I ssh on the precise64 host): for_window [class="URxvt" title="^.*@precise64.*$"] border normal Since I don't want to list all remote hosts I work on, I would just want to exclude my localhost (hparch) from the matcher, instead of including all others. Unfortunately this wont work: for_window [class="URxvt" title="^(?!.*@hparch).*$"] border normal I checked the regex with pcregrep, so it seems to work. Might there be a problem with the way i3 parses the regex? Problem already appeared [here](http://faq.i3wm.org/question/243/how-do-i-use-an-exclude-regex-in-i3-config/) but also no real solution.

My title bars contain "hostname: directory", e.g. "x200: ~", so here is what works for me: for_window [class="URxvt" title="^[^:]+:(?

You might just have to modify your regexp a bit. Have a look at http://i3wm.org/docs/debugging.html to enable the logfile. It will tell you whether a regexp matches or not. pcregrep (which you mentioned) is a faster alternative, though. By the way, I couldn’t get your regexp to work in pcregrep.

Also, why not use a shell alias like this one in the first place instead of doing hackish unreliable title matching? :-)

alias ssh='i3-msg border normal && ssh'

OMG, guess I lost sight of the obvious over tweaking the regex :) Thanks a lot!
