01:10 <ellisonch> hey, does anyone know if there is a way to turn off greedy matching in ocamllex? not the "shortest" setting instead of "parse", but a way to say "match the following regular expression with the fewest symbols as possible"

03:11 <ax> question here: i asked the mailing list with no responce, so i want to use objects/subtyping to allow for easier addition of new types of "events" in my event sequencer program. if i have a baseclass "event" that i subclass to create event2 which has an additional method do_something, can i retrieve this once i've placed an object of type event and event2 (coerced to be an event)

03:11 <ax> both in a list

03:12 <ax> is there a way to find out the type of an object, or is there an alternative design method that i should attempt?

03:13 <ax> basically i want users to be able to move all events around in time the same way, but some event subtypes would have additional methods that i'd like to be able to access

03:13 <ax> i'd like to store all the events in a common structure as well

03:13 <premchai21> You might have to do kludges with variant types.

03:14 <ax> so basically there is no elegant method for this?

03:18 <premchai21> I can't think of one off-hand, but then, I'm not an OCaml wizard either.

03:22 <ax> ok.. hmm

07:50 <pango_> ax: have you looked at the private row types of ocaml 3.09 ? I didn't understand what's said in the paper, but it looks like a way to solve that problem

07:52 <pango_> s/what's said/all what's said/ ( :) )

07:58 <vodka-goo> I don't use variants a lot

07:58 <vodka-goo> with lablgtk, guarrigue uses lots of that stuff

14:35 <ax> pango: thanks for the heads up, i'll check it out..

20:18 <dylan> Hi-ho, hi-ho, a finte state automata I go...
