Instead of using a quoted string to specify the class / title, the assign
command now uses criteria, just like the for_window command or the command
scopes.
An example comes here:
# Assign all Chromium windows (including popups) to workspace 1: www
assign [class="^Chromium$"] → 1: www
# Make the main browser window borderless
for_window [class="^Chromium$" title=" - Chromium$"] border none
This gives you more control over the matching process due to various reasons:
1) Criteria work case-sensitive by default. Use the (?i) option if you want a
case-insensitive match, like this:
assign [class="(?i)^ChroMIUM$"] → 1
2) class and instance of WM_CLASS can now be matched separately. For example,
when starting urxvt -name irssi, xprop will report this:
WM_CLASS(STRING) = "irssi", "URxvt"
The first part of this is the instance ("irssi"), the second part is the
class ("URxvt").
An appropriate assignment looks like this:
assign [class="^URxvt$" instance="irssi"] → 2
3) You can now freely use a forward slash (/) in all strings since that is no
longer used to separate class from title (in-band signaling is bad, mhkay?).
