[q-lang-users] Memory fun (was Re: Speeding up Q)

[Tim H. <q...@st...>]

Just had a thought, since we're talking fairly fundamental bits of Q...

I'm in the middle of hacking up a script to work on potentially large
bitmaps.

In a normal run, my script is well-behaved, albeit slow, using about 23M
RAM for a couple of minutes. That's OK. 

However, during a hacking phase when I'm introducing screwups by the
minute, it feels the urge to spew huge strings as it represents lists of
variously 65536 elements or even that many triples - and most noticeably
hogs up to a gig RAM in the process.

Am I right in thinking that the generation of error strings including
object-dumps is non-lazy?

It's a bit of a PITA trying to find the one or two list-elements on which
it can't do some function or other in the middle of such a large list.

Normal development process here is emacs and a mrxvt session or two in
whcih I either run the script or occasionally q -d theblighter.q or rarely
hack around in the interpreter. 

Is there any way to speed the process up a bit? Maybe set a few exceptions
or something?
