My understanding is that they forked Nix to replace its configuration language with Guile. Which is, at least in theory, pretty neat, and is probably very much interesting to Ludovic Courtès personally (he is the Guile maintainer, or was last I checked anyway). The practical benefits of Guix over NixOS are less clear to me, but what do I know.

Thanks for the clarification.
GNU Guix launches Posted Nov 26, 2012 13:51 UTC (Mon) by cmm (guest, #81305) [Link] The whole "standardized extension language" thing brings two benefits:
Which is all cool if you need to add an extension language to your program and haven't done so yet. If you already have one and it's not brain-dead — I don't really see much point in replacing it. Nix's configuration language does not seem brain-dead. As for the alternatives: Lua is younger than Guile, I think, and anyway it's basically a Scheme with syntax (and some questionable design choices mixed in, like not requiring you to declare variables. It's amazing how much typo-related pain that is customarily ascribed to the dynamically-typed nature of "scripting" languages is actually the result of this particular brain damage which most of them share...). I don't know how nice Python is as an extension language — but it is not backward-compatible with itself, which in my eyes makes it a joke (yes, I know the whole world is in love with it anyway). This is not GNU advocacy, I'm just trying to illustrate the fact that their extension language policy (as I understand it) is not arbitrary.

Yet Lua is much more used than Guile..

OTOH, Lua development is done behind closed doors.
GNU Guix launches Posted Nov 26, 2012 14:20 UTC (Mon) by cmm (guest, #81305) [Link] Yes, Lua is currently more used than Guile. You may want to consider that when Guile just started, everybody wondered "why not TCL?" or "why not Perl?". Later it got more like "why not Python?", and now it's "why not Lua?". The X in "why not X?" keeps changing, and Guile is still there. :) Also, as I said, surface syntax is really the least important thing in an extension/configuration language.

So? Perl or Python are still much, much more used than Guile..

You said it but it's not necessarily true: it's very likely that the syntax is a big part of the reasons why the Lisp family has so few users..

It's not just likely, it's a fact.
Why are we discussing on this infinitely tedious topic, anyway?
GNU Guix launches Posted Nov 26, 2012 16:34 UTC (Mon) by khim (subscriber, #9252) [Link] Because it's quite relevant. When guile was starting it promised choice of languages to use in extending their program. Translators were supposed to make it possible to write in any language of your choice. Kind of like CLR but on top of scheme. This was ambitious goal and it's implementation could have made guile much better then yet-another-language-run-of-the-mill-extension-language. Yet last time I've checked guile was yet-another-version-of-scheme (as obscure and unknown by general public as any other scheme dialect) which made it kind of useless as an extension language.
GNU Guix launches Posted Nov 26, 2012 16:42 UTC (Mon) by cmm (guest, #81305) [Link] Oh, I realize that. Thing is, the GNU folks realize that quite well too. And since they haven't changed their policy yet, what makes anyone think that rehashing the same tedious arguments yet again will have any effect? BTW, I believe Guile comes with a reasonably functional implementation of ECMAScript these days. I don't think anyone is using that, though. Perhaps that's selection bias at work (if you've already chosen Guile over, say, Lua, then it's a safe bet you like Scheme), and/or perhaps syntax is just Not Interesting enough anyway.

I read the name of that language as EMACSscript.
GNU Guix launches Posted Nov 27, 2012 0:09 UTC (Tue) by nix (subscriber, #2304) [Link]
It comes with that too :) at least, it comes with a (partial, last I checked) implementation of emacs lisp.
GNU Guix launches Posted Nov 26, 2012 21:30 UTC (Mon) by khim (subscriber, #9252) [Link] BTW, I believe Guile comes with a reasonably functional implementation of ECMAScript these days. Really? Since when? Manual says ECMAScript was not the first non-Schemey language implemented by Guile, but it was the first implemented for Guile's bytecode compiler. The goal was to support ECMAScript version 3.1, a relatively small language, but the implementor was completely irresponsible and got distracted by other things before finishing the standard library, and even some bits of the syntax. So, ECMAScript does deserve a mention in the manual, but it doesn't deserve an endorsement until its implementation is completed, perhaps by some more responsible hacker. Not a ringing endorsement to say the least. The only language which is kinda-sorta-maybe-supported is Emacs Lisp and it's not clear why anyone will want that if they don't like Scheme. P.S. It's funny, really. Guile is still pushed really hard by FSF backers and it's used in some fringe projects (like Lilypond, or Gnucash, or, I don't know, Guix) but when serious people need real scripting for their real needs they choose... something else. In fact you can easily see when project built around guile tries to finally reach normal people: it's when guile is finally get a sane alternative.

Wow, that manual entry actually insults someone who contributed code for free? Good job on completely pushing away other on-the-fence contributors. Some people do have more to do with their time than try to fully implement a complex feature for nothing in return besides potential contempt and ridicule.

I suspect you'll find the manual entry was written by the very person who got distracted. :) it feels like self-deprecation to me.
GNU Guix launches Posted Nov 27, 2012 1:27 UTC (Tue) by elanthis (guest, #6227) [Link]
Ah, alright. That obviously doesn't translate very well with a quick reading. :)
GNU Guix launches Posted Nov 26, 2012 17:57 UTC (Mon) by vonbrand (subscriber, #4458) [Link] "Uniform surface syntax" among extension languages doesn't matter that much, what matters much more is uniform(ish) syntax/programming model with whatever the user does all day long. Scheme might be the nicest extension language around, but if you program C all day it will be all Greek to you. Plus what "power users" really do is to tweak the configuration a bit, or add some piece of code found on the Internet. They do not waste a significant slice of their time futzing around with configurations/extensions of the tools.

I think this blurb from a mailinglist[1] does a better job describing Guix/Nix than you did:
Guix & Nix
Nix is really two things: a package build tool, implemented by a library
