hey,
so gambit is really awesome; especially the debugger; however I'm running into some trivial practical issues -- and curious how others are solving it
1) sed/awk/grep/perl if possible, i'd like to use gambit for these type of apps instead (being slower is fine; i just want everything in scheme for now) -- is there a good way to do regex matching in gambit?
2) fprintf/format pp and display are cool -- but sometimes, I really really want control over my output; how is this generally done in gambit? things like "print this number with 8 chars width, 3 digits after the decimal point" seems kind of hard to phrase
thanks!
keep up the good work

Both are fully portable R5RS Scheme and much more flexible than the standard alternatives.

IrRegex is indeed a great regex implementation. Using JazzScheme you can access it with (import irregex) as it is standard module.

I concur. Irregex is my favourite portable regular expression library.

Thanks for the suggestion. I did not know it existed and it looks really nice.

I gave up portability a while ago.
Could those libraries benefit from Gambit's extentions of Scheme?
Trading portability for more efficiency shouldn't be that bad (considering that those libs are not to change a lot in the next few decades), and finding the Gambit-specific versions in the dumping ground would be nice too…
P!

Actually, Irregex will likely change quite a lot in the short-term. It's algorithmically fast, but the code hasn't been bummed at all yet which will make a huge difference. So you could fine-tune some things for Gambit, but will have a lot of work to do keeping sync with the upstream changes (at least for now).
Given time I also want to do a non-backtracking NFA matcher for when you want a lighter footprint, and a sublinear-time DFA just to show off on benchmarks :)
