How do I tag console based programs?
|Related issue:||-||Related Message:||-|
When console based programs like irssi are started with a terminal like
urxvt -e irssi, they usually just change the WM_NAME of the terminal and per default, subtle uses both of the WM_CLASS values for tagging.
The problem about that is, that the tagging is normally done before the terminal really starts the desired app. To avoid that all better known terminals support the -name argument which changes the instance value (first string) of the WM_CLASS:
urxvt -name irssi -e irssi
Another problem is that terminals retain their class value (second string) of the WM_CLASS and may match other tags like:
1 tag "terms" do 2 match "urxvt" 3 end
The common solution to bypass is this to use the :instance matcher, which just matches when for the specific instance value. So the easiest way to reliable match this client is a tag like this:
1 tag "irssi" do 2 match :instance => "irssi" 3 end
Following table shows the WM_NAME and WM_CLASS output of xprop of the various combinations:
|urxvt -e irssi||irssi||urxvt, URxvt|
|urxvt -name irssi||urxvt||irssi, URxvt|
|urxvt -name irssi -e irssi||irssi||irssi, URxvt|
Please have a look at the tagging wiki page for more information.
