06:06 SinDoc: Any workflow documented on using Racket on the command-line --my sole interface to a real machine is SSH. The REPL invoked by the racket command doesn't keep history!
06:08 noelwelsh: Run ssh through Emacs?
06:09 SinDoc: I can SSH to a machine that HAS Emacs; not the other way around!
06:13 noelwelsh: Well, you can run GNU Readline w/ Racket (see the docs). I don't know if it keeps history, but that's one thing to look at.
06:13 noelwelsh: Alternatively running ssh or a shell from emacs will allow you to save the history just as you'd save any other buffer
06:18 SinDoc: noelwelsh: Oh, I didn't expect Emacs to this _this_ :)
06:18 SinDoc: Yet, it does!
06:19 SinDoc: Thanks noelwelsh
06:20 noelwelsh: You're welcome!
06:26 SinDoc: I/O passes by Emacs while using M-x shell. Not the case though for M-x term.

08:50 SinDoc: bremner: I didn't; until you mentioned it and I looked it up: http://www.nongnu.org/geiser/ The Wikipedia disambiguation page wasn't particularly helpful though :)
08:51 bremner: Yeah, I'm not sure how Old Faithful will help your problem ;)
08:53 SinDoc: I happned to see Racket 5.0.1 mentioned on their website. I'll give feedback once the setup will have completed.
09:01 bremner: geiser works ok with 5.1.1 for me
09:04 (join) samth_
09:06 SinDoc: bremner: I get 'Cannot open load file: minibuffer' after M-x geiser
09:06 hkBst: why does (shared ((l `(1 3 . ,l))) l) work fine, but (shared ((l `(,@(list 1 3) . ,l))) l) produce an unintelligible error?
09:06 bremner: SinDoc: what version of emacs?
09:06 SinDoc: bremner: 22.3.1
09:07 bremner: ah, too old, sorry
09:07 SinDoc: Yeah, they say: Emacs 23.2
09:08 bremner: dyslexia doesn't count ;)
09:10 bremner: I guess you could build emacs in your homedir. Or maybe one of the other emacs scheme modes would work. I have only used geiser.
09:11 SinDoc: I'm not giving up easy; it turns out I can sudo on another machine; so far, three-level deep ssh, which reminds me of inception, the movie
09:12 bremner: geiser also supports remote REPLs, for another way to get overcomplicated ;)
09:13 bremner: you might need to use ssh to tunnel the repl to a local machine.
09:15 SinDoc: that would be cool; I have never tried a back tunnel to a Windows machine; the main reason why I'm doing all this is because I'm stuck with a Windows client with tons of constraints.
09:17 SinDoc: Otherwise, I would've installed DrRacket, which woudn't take more than a few seconds
09:17 SinDoc: BTW, I'm quite close to a Racket mirror, which makes me happy :)

13:15 EgnartsMs: i need some way to represent a generic random-access sequence of values, like vector

16:23 Demosthenex: otoh, if i'm doing that with a huge hash (several hundred meg) aren't i using the mem twice?
16:23 Demosthenex: yes, i might just use a DB instead ;]
16:29 samth: yes, it'll duplicate the memory of the hash structure (but not the keys/values)
16:29 Demosthenex: thats encouraging

17:31 riddochc: Hey.  So I figured out the screwy solaris missing 'ar' thing I was fighting with yesterday, and have moved on to a file-locking thing that looks like it came up recently on the list...
17:32 riddochc: I'm pulling down the git repo now, but it looks like there *is* a commit, about a month old, that should address the issue.  My question:
17:33 riddochc: What I'm trying to build is 5.1.1, but the patch appears newer than that.  Is the master branch of racket generally stable enough that I can just move up to that patch and build from there, or should I branch from 5.1.1 and just tack on that patch?
17:35 riddochc: The thread on the list had the subject: flock() stops racket-5.1.1 build on Solaris x86
17:35 bremner: probably you should patch against master if you want your patch included upstream. Things change pretty fast.
17:37 riddochc: bremner: Someone beat me to it, but it's not yet in a released version.  Should I run the tip of master, or just rebase (I think that's the word?) that one commit?
17:38 bremner: riddochc: I've had pretty good luck cherry-picking patches from master on to the stable branch; it's up to you really.
17:39 riddochc: cherry-pick, yes, that's it.  I'll give it a try.  Was just wondering whether I'd do just as well to simply build what's currently on master.
17:40 stamourv: riddochc: master is generally quite stable.
17:40 riddochc: stamourv: Cool, thanks.
17:41 riddochc: I don't follow the development closely enough to see what's currently in-progress.
17:42 stamourv: drdr.racket-lang.org will usually tell you if master is broken.
17:42 riddochc: Oh, cool.  I wasn't aware of that.  Thanks.
17:47 riddochc: Also, I'm curious, since it's not mentioned in the 'Anticipated Questions' part of racket-lang.org/new-name.html - and it's really only a curiosity, since I'm a complete outsider to the process... is there any relationship between the name change and support for R6RS?

17:52 samth: riddochc: not really, Racket currently supports R6RS, and PLT Scheme (the old name) did as well

17:53 samth: riddochc: if you're using racket, you can safely ignore all the fuss
17:59 riddochc: samth: Hmm. Okay.
