I really hope you're not kidding, because that sounds totally
insane. Sure, xprops output sucks, but I don't care. Also wmii
won't be able to provide you equivalent output like xprops,
because xprops prints all(!) atom properties associated with a
window, you don't want to know how much crap you have todo, to
get something similiar (beside reinventing square wheels). (I
expect not under 2kSLOC at least for dumping/querying the
stuff).

Then implementing yet another regex-matching/globbing rule
engine similiar to awk, to just match some properties to write
some tags to windows inside wmii, what do you think how many
SLOC will that be? I expect at least 0.5-1kSLOC for very basic
stuff. Then you need an fs-interface for it which will need also
approx. 50 SLOC additional lines. Thus all in all we would be
around 10kSLOC I presume, for stuff which can be much more
simplier I already showed. We could even get rid of /def/tag
stuff, because wmiirc could decide what the fallback tag should
be.

That is a good point, but you won't notice, because if you get a
window with an empty tags file, it is displayed off-screen until
the tags file has been written. You can write about 100 tags per
second, thus all in all a non-issue.
