Emacs does that ... but in lisp :)
More seriously, instead of creating yet another kind of addons...
I've been thinking for some time about reusing the translators as a
mean to index meta data from file content, by adding a SniffAndIndex()
method or so...
that would fill in atribs from ID3 for example... (not exactly the best
example but well... or get image w & h form the file). I guess we could
use that for mime sniffing as well.
I think translators are probably the best suited to know what is inside
files the support. Also when converting files with them they would just
have to call their SniffAndIndex method to put the meta data right
away. That'd save ppl form adding it manually, something we should have
done for long, other OS already do.
There might be a perf issue though if we load every translator each
time...
