http forward proxy
by Patrick D. Logan 18 Avr '07

18 Avr '07

it looks like snow currently does not support accessing the site from behind a firewall? The http, tcp code that uses curl could add this fairly easily, but otherwise the tcp code using the particular scheme's tcp could would have to rely on those supporting forward proxies. (And it looks like gambit does not have built-in support for proxies?) I wonder if it would be useful for snow to have a way of explicitly avoiding a particualr system's tcp library in favor of the curl option, especially with an option to specify proxy information? Thanks, Patrick

I just registered this domain; if the folks running the Snowfort right now want it, please let me know. I couldn't get Snowfort in any other TLD; must be a popular name for squatting! -Evan ________________________________________________________________________ Evan Prodromou <evan(a)prodromou.name> http://evan.prodromou.name/

R6RS

Hi, all. I just stumbled across the Snowfort, and I'm glad to see the project moving. I have a simple, potentially dumb question, which is: is there a planned upgrade path from the snow package system to the new library form in R6RS? Should there be? -Evan ________________________________________________________________________ Evan Prodromou <evan(a)prodromou.name> http://evan.prodromou.name/

Release of generic Snow v1.1.0
by Marc Feeley 05 Avr '07

05 Avr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Generic Snow v1.1.0 has been released and is available on the Snowfort. For installation instructions see: http://snow.iro.umontreal.ca/?tab=Installing If you have generic Snow v1.0.0 currently installed and you plan on using Snow with Gambit and Chicken you should first install the latest versions of those systems (Gambit-C 4.0 beta 22 and Chicken 2.608). This can be done with the command: snowman --install host-gambit host-chicken Here are the highlights of the new version (check the online documentation for details): * "define" and "define-macro" (without the star) are now available in the "provide:" section and package body. The core packages now use "define" instead of "define*" except when there are optional parameters. * define-syntax/syntax-rules can be used in the "provide:" section and package body. It works on most host Scheme systems but for Gambit you will have to set SNOW_HOST=gambit-sc and for Chicken you will have to set SNOW_HOST=chicken-sc (this loads the portable syntax-case macro expander). * "include*" works as documented on all systems. The filename is relative to the file that contains the include* form. * The package* form is well integrated with Gambit and Chicken. The package namespace is properly maintained on those systems, both in interpreted and compiled packages. Compiled and interpreted packages can coexist. The snow.scm file has been reorganized to make it easy to add better support for a given Scheme system. * The define-record* form is mapped to the native record definition form on all supported Scheme systems (except SCM). * Change of syntax of the snowman commands (the "--" is dropped on the commands, i.e. "snowman install foo/v1"). * Kawa is now fully supported.

Installing snow with guile
by Rodney Topor 20 Mar '07

20 Mar '07

Our sysadmin has just installed Guile 1.8.1 on our Linux server, but I can't configure snow with it. This is a trace of what happened: [s352978@dwarf v1.0.0]$ ./configure --site-root=$HOME Searching for the Scheme systems accessible in the current PATH: Guile 1.8.1 -> /opt/bin/guile These systems were not found (you might want to check the URL to install them): bigloo -> http://www-sop.inria.fr/mimosa/fp/Bigloo ... Testing the Scheme systems: ----------------------------------------------- testing guile START OF SELF TEST exceptions, records, optional parameters, fixnum, homovector, time, bignum, string, filesys, hostossh: unknowncommand: command not found , random, extio, genport, digest, aes, httpERROR: In procedure fport_fill_input: ERROR: Connection reset by peer guile has ***failed*** the self test ----------------------------------------------- *** None of the installed Scheme systems support Scheme Now! *** Consequently, the Scheme Now! framework can't be installed. *** You might want to install a Scheme system, add it to your *** PATH, and then run the configure script again. [s352978@dwarf v1.0.0]$ Can anyone explain what the problem might be? A guile installation error? A snow problem? (This is my first attempt at using snow, a step towards using lalr-scm.)
