[toronto-lisp] help deciphering Scheme macro(s)
by Paul Tarvydas 23 Feb '13

23 Feb '13

I'm converting this PEG parser from R5RS scheme to CL: http://dev.lshift.net/tonyg/json-scheme/ I'm having trouble (I think) deciphering how the following macro is expanded (esp. the 2nd line "(#t alternative) ...") ... ((_ #f "alt" nt body ((/ alternative ...) rest ...)) (packrat-check (packrat-parser #f "alts" nt (#t alternative) ...) (lambda (result) (packrat-parser #f "alt" nt body (rest ...))))) ... Let's say the input is something simple, such as "...((x <- #\y (/ #\a #\b)) x) ... " (i.e. parse a 'y' followed by an 'a' or a 'b', assign 'y' to the variable x, then return that variable x). Does someone know how to "read" this macro? Or, can someone tell me the exact steps in getting any working implementation of R5RS scheme up on linux (mint/ubuntu/debian) or Win7 and display the expanded macro? (I seem to hit confusing roadblocks with racket, chicken, cpscm+scm2lisp). Thanks pt

[toronto-lisp] Anybody done the Little Schemer?
by Sam Roberts 23 Jan '13

23 Jan '13

It's trying to teach me a very consistent, but not very direct (IMO), way of writing recursive lambdas, and I'm wondering why. Particularly the why of the "first commandment". Is there anybody on this list interesting in bouncing ideas around about this book? Sam

[toronto-lisp] Memo
by Leo Zovic 10 Jan '13

10 Jan '13

1. Notes have been sent off to Paul. We didn't actually do real-time note-taking this time because it was too interesting for anyone to focus on recording. How does everyone feel about doing audio recordings for transcription purposes in the future? 2. We're booked in at Bento Miso for the following days. January was a bit anomalous, since the first Tuesday was actually Jan 1, but we're now back on our regular schedule. 1. Tuesday Feb 5 2013 2. Tuesday Mar 5 2013 3. Tuesday Apr 2 2013 4. Tuesday May 7 2013 5. Tuesday Jun 4 2013 3. Dann is giving a talk about the Web Audio API on Thursday, Jan 17 at Bento Miso. It looks to be interesting (also on the bill is Dan talking about Angular.JS, a reactive JavaScript framework for application front-ends). Meetup page here<http://www.meetup.com/torontojs/events/98546072/>. I'll try to show up, but may be out of luck; there seems to be a waiting list already. Also, Happy New Year to anyone that wasn't at the last meeting. -Leo

[toronto-lisp] Global Code Retreat and Other Minutia
by Leo Zovic 04 Dec '12

04 Dec '12

Hello everyone. Three things that I want to get out there in advance of publishing the (not very extensive) notes. 1 - This link was already posted to the mailing list, but not everyone knew about it when I asked at today's meeting, so... Global Day of Coderetreat <https://guestlistapp.com/events/130467> is happening this coming Saturday I'll be there with a laptop and prepped runtimes/environments for Common Lisp, Clojure, Haskell, Python, Forth and SWI-Prolog (and I guess technically Elisp, Perl, JavaScript and C too). I've been poking at Haskell with intent, while Prolog and Forth are next on my to-learn list, so I'll be biased in what I want to work with. About half of tonights' group was going to be there in any case, so the lispers/functional programmers definitely won't be lonely. Registration is closed, but it's apparently ok to just show up. 2 - There's a similar monthly event happening. Details on the meetup page<http://www.meetup.com/Toronto-Code-Retreat/>, though the next one doesn't seem to be scheduled yet (correct me if that's the wrong link). 3 - The fine folks at Bento Miso <http://bentomiso.com/> have offered to host us for the next few months, and the attending group was ok with this. The next meeting of the Toronto Lisp Group will happen on the 8th of January, and we've been penciled in for the first Tuesdays of February and March. 4 - Ok, four. The toronto-haskell<https://groups.google.com/forum/?fromgroups#%21forum/toronto-haskell>group is currently asking members for feedback on their next meeting date. It'll be one of (list <Thursday, Dec 6> <Friday, Dec 7> <Wednesday, Dec 12>); they meet at the Toronto hacklab <http://hacklab.to/>, typically starting at 7:00 pm. -Leo
