Re: [linux-audio-dev] [semi-OT] EEL 0.1.0

This is what you are looking for: http://tinyurl.com/5bekn The url above is pointing to the cvs-entry of the file eval-c.scm in the snd sound editor. Eval-c is c-code using s-expressions (which I know you hate, allthough I don't know why, perhaps you are crazy...), compiled, linked and run on the fly. Place the cursor above an eval-c block in emacs, press ctrl+alt+x, and there it flies. (I have also added support for classes and a lot more, but those additions hasn't been made public yet.) By the way, this is the way lrdf-support is handled in snd. Quoting: " EVAL-C ------ eval-c takes as arguments lisp- and C-like blocks, generates c-code from it, and runs it. Some reasons to use eval-c: * Easy integration of c-code from within lisp. Mix C and Lisp in the same source without making it look strange. (hopefully) * Use lisp-macros to generate c-code. (There is a special macro function called "define-c-macro" that works with eval-c) * Generate/compile/link/run c-code on the fly. * Some people think prefix notation is nice. * Speed. C is faster than guile. * Hides guile-semantic to access C-code from guile. Less need to read the guile manual. * Global functions does not need to be defined at the top-level. (that is a good thing, right?) Examples. -------- The simplest fibonacci function: (define-c <int> (fib ((<int> n)) (if (< n 2) (return n) (return (+ (fib (- n 1)) (fib (- n 2))))))) The define-c macro will produce the following code: (eval-c "" (public (<int> fib (lambda ((<int> n)) (if (< n 2) (return n) (return (+ (fib (- n 1)) (fib (- n 2))))))))) The "public" macro will change the code so that it looks something like this: (eval-c "" (<int> fib (lambda ((<int> n)) (if (< n 2) (return n) (return (+ (fib (- n 1)) (fib (- n 2))))))) (<static-SCM> fib_eval_c_helper (lambda ((<SCM> n)) (return (MAKE_INTEGER (fib (GET_INTEGER n)))))) (run-now (scm_c_define_gsubr "fib" 1 0 0 fib_eval_c_helper))) And after running the "lambda", "if" and "run-now" macros, eval-c will produce and run the following c-code: int fib (int n){ if ((n < 2)) return (n); else return ((fib ((n - 1)) + fib ((n - 2)))); } static SCM fib_eval_c_helper (SCM n){ return (MAKE_INTEGER (fib (GET_INTEGER (n)))); } static void run_now_1 (){ scm_c_define_gsubr ("fib", 1, 0, 0, fib_eval_c_helper); } The first function is the fibonacci generator, and the second function is the guile-wrapper. (GET_INTEGER and MAKE_INTEGER are just simple C macros.) "run_now"-functions are run once when the file is loaded. >From guile you now have a function called "fib" which takes one argument. Hello world looks like this: (eval-c "" (run-now (printf (string "Hello world!\\n")))) First argument to eval-c is a string with compiling/linking options. Usually just "", but can be "-lsnd" or something if needed. " --

hi everyone! i have just accepted a commercial advertisement on linux-audio-announce, because i considered it perfectly on topic and relevant to the linux audio community. however, some of you may disagree. to let everyone decide for themselves, i'm asking advertisers to include the string [adv] or [ADV] in their subject so that subscribers who do not wish to see commercial ads can easily filter them out. feedback to my private address if possible, i'll summarize to the list. regards, jörn

[linux-audio-dev] Tracktion, JUCE and Linux

by Rui Nuno Capela

Hi everyone, About to let you all know that I took this LAU thread to Jules, Trackion's and JUCE author, and that I got some promising good news. Besides, being sorry of posting the whole thread here, I'm also cross-posting this to LAD, as I think it must be of interest there too. Read on. So to put a long story short: help is being asked to write the native Linux Audio and MIDI components of the JUCE C++ framework, which among other things, would rush the Tracktion Linux port, hopefully this very year :P Hope to be doing TheRightThing.

Below you can find an excerpt of a recent thread that was being taken place on linux-audio-users maillist, regarding Tracktion, which is raising some interest on the Linux Audio community, myself included. As a developer, I'm quite excited to know whether the JUCE Linux port is evolving, and just in case you need help, I'll be glad to give you a hand, or two :) You can read my own posts below, regarding me and others potential in willing to help you in delivering a genuine and native JUCE port to our beloved operating system.

However, quoted from the JUCE's to-do-list (http://www.rawmaterialsoftware.com/juce/todo.html): - get the Linux port up and running.. So, given that JUCE is being released under the GPL, and if some of the LADs are willing to help, things could just happen sooner than later ;) I mean, having a Linux native Trackion port (hopefully with ALSA and JACK support). Tracktion is closed-source however, with commercial rights owned by Mackie. Or so I think. I guess the linux port will be also closed-source. But I would rather buy it, instead of running it under the nasty effects of wine ;) OK. My idea is first probing you LAUs/LADs, my self included, if it makes any sense on lobbying for the Trackion linux port.

Yes, AFAIK Tracktion is a Mackie product and only free for a limited time (however the fact that it's been distributed for free seems to suggest a free binary for linux would not be out of the question). > OK. My idea is first probing you LAUs/LADs, my self included, if it > makes any sense on lobbying for the Trackion linux port. I'm of the opinion that choice is good, therefore having another quality (and widely used/supported) DAW would be great for linux. Also, once JUICE is ported, that will provide another great resource for future linux audio development. Finally, the fact that this project is affiliated with Mackie, a HUGE name in the "industry" could work greatly to the benefit if linux/audio. I mean if we could get a linux port of Traction on mackie ftp servers? Well, people would take notice. > Second, our X/ALSA/JACK expertise (!) could be offered towards a early > JUCE port and help Jules|Mackie in delivering a linux beta product in > no time. > > Anyone interested?

Yes, he dropped by the Linux Audio stand at last year's Sounds Expo. I gave him a (by then) rather weary and incomprehensible spiel about how much fun JACK was, and he talked a bit about the sale of Tracktion to Mackie, which had just happened. Nice enough chap, but he probably thought we were a bunch of wasters. He certainly wasn't entirely unfamiliar with Linux even then though.

Well, hardware is, what you can sell even to free software people, and even expensive hardware, as RME has shown. We all need speakers, for example, and Mackie (or Tapco) produces great speakers. If they would support FLOSS development, I'd be even more inclined to prefer their stuff over others'.

The so-called framework (JUCE) is actualy released under an open-source license (GPL), but I think its up with us, linux audio users and developers, to show Jules what our interests really are, and offer our kind help or participation in whatever will be needed to bring Tracktion to the Linux arena. IMO, the main issue is about bringing JUCE to Linux in the first place. Well, that's the whole purpose of my notice. Speaking for myself, I believe to fit both interests, as an user and as a developer. Please note that I'm not asking for Trackion being open-source. Nor am I assuming it will ever be. I'm just trying to ease the route to reach a true native Linux port. Is up to Mackie whether it will be priced or not. I have no reason to believe Mackie will release Tracktion as open-source, even though Mackie is in the hardware business, not software. OTOH, and as already noticed here, JUCE seems to be a real gem, and as open-source as I trust it is, it can be a real promising cross-platform C++ GUI, Audio and MIDI, all-in-one-toolkit-solution for Linux. Yes, it does seems yet another one, but this time it would be highly specific for building cross-platform DAWs :) The following should be essential linux-platform-specific "underwear" to stuff into JUCE: - GUI: Xorg, freedesktop.org - Audio: JACK, ALSA - MIDI: ALSA obviously being the cream of the crop of our Linux and Audio/MIDI technology, IMO. OK. Next step should be perhaps about asking on LAD if this whole idea makes sense, or is it a plain dead-end. Hopefully not. Then push the whole thread to Jules mailbox and see what comes about ;) Cheers. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org ========================================================================== ---------------------------- Original Message ---------------------------- Subject: Re: Tracktion, JUCE and Linux From: "Julian Storer" <jules(a)rawmaterialsoftware.com> Date: Sun, January 9, 2005 12:40 To: "Rui Nuno Capela" <rncbc(a)rncbc.org> Thanks for that.

Even if its not on a release-level state, I think me and some other LADs (Linux Audio Developers) are willing to help you and your friend in the making. You can guess that I'm really motivated in the first place, being this very mail exchange just the superficial evidence ;) First of all, I would ask you if its alright to cross-post your reply(ies) to the linux-audio-devel/user maillist, which everyone will find quite encouraging, or so I believe. Second question goes about public hosting of the JUCE project, and what's your policy about that. For example, are you willing to host JUCE under sourceforge.net, given that you're releasing it under an open-source license (GPL). This is just an humble suggestion. Your thoughts may vary of course. Let us know of your opinion, if that won't take you from what you love.

Just drop me a line, or on the linux-audio-dev list, when you're ready. Meanwhile, if that's not too intrusive of course, would you tap on your friend, the one who's dealing with the linux code, and handing him/her a note? I'm almost certain that both of you would take collaboration as a good idea. Would you forward him/her this thread?

[linux-audio-dev] [semi-OT] EEL 0.1.0

by David Olofson

(This is not strictly audio oriented, though the project started out as part of a sound engine, and I figured it might be of some interest to some people here.) There! I've decided the new, rewritten EEL scripting engine is about ready to start playing around with. There is some work left to do (some refactoring, some more built-in classes etc, file I/O and networking modules and stuff), but it should be totally possible to actually do something with it already, I think. EEL is NOT just a spare time project! I get paid to work on this. That said, I also have a genuine interest in EEL itself, and I have a few spare time projects that do or will use EEL. (Which basically means I'm working 12/7 or so on this or on projects using it ATM... *hehe*) Home site (or excuse for...) here: http://eel.olofson.net/ Direct download: http://eel.olofson.net/download/EEL-0.1.0.tar.gz Some facts: * Language inspired by C, Pascal, BASIC, Lua etc. * Designed for real time applications from the ground up. * Dynamic typing; nil, real, integer, boolean + classes. * Classes: string and array. (Tables are next.) * (Plans include user defined classes and operators.) * Automatic memory management. * Exceptions. (try...except, throw, retry.) * Nested functions with upvalues. * Recursion, including mutual. * Functions can have optional or tuple arguments. * Terms and indices can be lists - operations multiplexed. * Compile time import of modules, into scope or namespace. * Run time loading of modules. * Simple C API for embedding in applications. * Stackless bytecode VM with variable size instructions. * Compiler with (mostly unused) optimization framework. * Speed: Better than 50% of Lua, despite stupid compiler. * 17463 lines of (hopefully) portable C code. * LGPL. (Maybe LGPL + MIT/X11, if it makes life easier.) //David Olofson - Programmer, Composer, Open Source Advocate .- Audiality -----------------------------------------------. | Free/Open Source audio engine for games and multimedia. | | MIDI, modular synthesis, real time effects, scripting,... | `-----------------------------------> http://audiality.org -' --- http://olofson.net --- http://www.reologica.se ---
