Well, the latter version is not present in hg. config.def.h is
like in 4.9 I think.
Anyways. if you use xprop(1) to gather the window properties
have a look to the WM_CLASS property, for Gimp windows it looks
like:
WM_CLASS(STRING) = "gimp", "Gimp"
Rules are expected the following way:
Rule rules[] = {
/* class */ /* instance */ /* title */ /* tags ref */ /* isfloating */
{ "Gimp", "gimp", NULL, NULL, True }
...
};
So the first pattern should be a substring of the actual window
class (which is the second argument in WM_CLASS presented by xprop(1)),
the second pattern should be a substring of the actual window
instance (which is the first argument in WM_CLASS presented by xprop(1)),
the third pattern should be a substring of the actual window
title.
Usually the class/instance never changes and is fixed to all
windows of a certain application, the title is the more dynamic
thing -- but unless you do not re-apply the rules using Mod1-r
during runtime, they are only applied at the creation time of a
window, so it is safe for example to use xterm -title "bla" and
match for "bla" in the rules in the title.
If either value is NULL it is not checked or not applied.
Hope this helps,
