Trying to run Emacs with Gambit-C
by urrozalf＠vcn.bc.ca 24 Mar '07

24 Mar '07

Hello there Scheme gurus, I am trying to run Gambit-C and using Emacs as the editor, but I can't fugure out how to do it. First of all I am running Solaris 9 on an old Sun box. I have downloaded the Gambit files and the Emacs files, expanded and made both of them. At the beginning I was having some issues with the PATH, but I have that fixed right now. I can use the Gambit Interpreter (gsi) and the compiler (gsc). The problem is, I have to use a separate text editor, to edit the files, and here is where I wan to use Emacs. What I have right now, is the following structure /export/home/alfonso/MyPrograms/Gambit-C/ and also /export/home/alfonso/MyProgrmas/Emacs/ I also know, that I have this, somewhere else on the hard drive: /usr/local/Gambit-C/ I don't know, how it got there, but there it is. I created an .emacs file, 0n /export/home/alfonso/ which contains the following: (autoload 'gambit-inferior-mode "gambit" "Hook Gambit mode into cmuscheme.") (autoload 'gambit-mode "gambit" "Hool Gambit mode into scheme.") (add-hook 'inferior-scheme-mode-hook (function gambit-inferior-mode)) (add-hook 'scheme-mode-hook (function gambit-mode)) (setq scheme-program-name "gsi -:d-") (setq load-path (cons "/usr/local/Gambit-C/share/emacs/site-lisp" load-path)) (setq scheme-program-name "/tmp/gsi -:d-") (setq gambit-highlight-color "gray") (setq ganbit-repl-command-prefix "-e") (require 'gambit) When I type emacs, open the editor, but it tell me, there is an error, if I remove the (require 'gambit) line and do 'M-x run-scheme' it tells me there is an error also. I don't know what I am doing wrong, or what I am missing, please help me to figure out this problem, I know I am pretty close, but no cigar. If I can't figure this thing out, I will have to go and dowmload PLT scheme, for UNix, and give it a try. Thanks. Alfonso G. Urroz

Meroon and syntax-case?
by Phil Dawes 23 Mar '07

23 Mar '07

Hi Gambit List, I really like the meroonet object system, however my program contains quite a few syntax-case macros and the meroonet common-lisp style macros don't work once syntax-case is loaded. I've found that I can switch between the two macro systems using: (define (switch-to-lisp-macros) (set! ##expand-source (lambda (src) src))) (define (switch-to-syntax-rules-macros) (set! ##expand-source (lambda (src) (sc-expand src)))) ... however this is both a hassle and a global change which I'm guessing prob won't work with threading etc.. Has anybody attempted to build a meroon style system using syntax-case macros? Any pointers would be much appreciated. Many thanks, Phil

persistence alternatives
by Aycan iRiCAN 14 Mar '07

I just wanna know what type of methods you guys prefere for persistence. We used prevalence with common lisp (wrote functions for every destructive operation and serialize the method names and arguments). What are other alternatives or future trends? Best Regards, -- Aycan iRiCAN KOR Bilişim Teknolojileri http://www.core.gen.tr/

Gtk bindings?
by Andrew Lentvorski 09 Mar '07

09 Mar '07

Does anybody have a pointer to Gtk bindings for Gambit? ObGrumble: I don't see a good way to search the mailing list archives other than Google. If that is really the only way, we ought to put a link somewhere that fills in a Google search page with an appropriate limiter (aka site:umontreal.ca ) -a

open-tcp-server
by James Cash 09 Mar '07

09 Mar '07

Hi, I'm trying to write a basic webserver in Gambit Scheme. However, my efforts are being stymied at the very beginning by the fact that I can't seem to even use the most basic procedures properly...can anyone help? Here's what I'm trying to do now: (In REPL:) Gambit Version 4.0 beta 21 > (define s (open-tcp-server (list port-number: 8080 eol-encoding: 'cr-lf))) > (define p (read s)) Then, I go to a browser (tried in both Opera and Firefox) http://localhost:8080 The browser goes to the page, and the `(read s)' stops blocking Back at REPL: > (read-line p) "GET / HTTP/1.1" > (display "content-type: text/plain\n" p) > (display "Hello World!\n" p) > (force-output p) ...And nothing happens...the page keeps trying to load, nothing is shown. What am I doing wrong? I tried looking at the code in the example webserver, but it didn't help much, since its much more complicated than what I'm trying to do here. Can anyone help? Much obliged, James

> Dominique congratulations for having release the first non-core Snow > package! I think lalr-scm was a good candidate for this. Turning it into a Sno package solved many packaging problems. > So what's next... a Snow package for Silex? Then we would have a > nice portable lex/yacc equivalent for Scheme. That would be nice. But the first step would be to turn Silex into a macro to achieve a better integration with lalr-scm. > Perhaps we should start a "Snow package wish list" so those of us > with idle cycles (and some of my students) can get to work on > implementing or converting the most urgently needed packages. Here is my wish list: - web application server infrastructure, whatever that means - XML parser / writer (can SSAX-SXML be easily repackaged?) - JSON support (I will probably contribute that one real soon) - Database support (I have a prototype for the native PostgreSQL interface) - Logging I will also eventually contribute the following packages: - Asterisk Manager API interface (www.voip-info.org) - FastAGI interface (www.voip-info.org) > Let's hope there will be lots of Snow in the near future. I really like snow! Dominique

I would also like to build a list of projects using lalr-scm. So if use it for one of your projects, be it a hobby, an open-source project or a commercial product, let me know! I would also like to build a repository of open-source grammars for easy bootstrapping of language tools.If you have simple or complex grammars you'd be willing to share with others, send them to me and I'll include them in the next release.
