[Chicken-users] chicken-spock and 'load'

[Sudarshan S Chawathe]

I am probably missing something very obvious, but I cannot seem to
figure out how to load one file (Scheme source) in another when using
chicken-spock.  I'd be grateful for any pointers.

Should I be using some other mechanism to pull in code and libraries?
(What I'm hoping to do is, for example, use portable SRFI
implementations within my code destined for Javascript via
chicken-spock.)

For example, I have in file t.scm:

  (load "t2.scm")
  (define t t2)
  (print t)

and in t2.scm:
 
  (define t2 't2)
 
Running chicken-spock t.scm gives:

  /* CODE GENERATED BY SPOCK 0 */
  var t3 = function (k1) {
   return ___load(k1, "t2.scm");
  };
  SPOCK.run(t3);
  var t5 = function (k2) {
   ___t = ___t2;// set! t
   return ___print(k2, ___t);
  };
  SPOCK.run(t5);
  SPOCK.flush();
  /* END OF GENERATED CODE */

which generates Javascript errors about ___t2 being undefined and syntax
error in t2.scm.

I'll take this opportunity to wish everyone the season's best.

[Chicken-users] Any decent web development framework

[机械唯物主义 : linjunhalida]

Hi scheme users,

I'm a rails programmer, and knows scheme long time ago but don't have
chance to write scheme code in production level. I want to use scheme
for website development but it turns out there is no decent framework
for web development in chicken.

Is there any recommendations? awful is not very useful.
Any library same as Rails or Sinatra?

Sinatra writes like this:

(get "/" (lambda (request)  "hello")
(get "/from/:id" (lambda (request) (sprintf "hello ~A" (request 'id
(get "/page/:id" (lambda (request)
  (let ((data ($query (from pages) (where (= id (request 'id))
(render "templates/page" ('data data

Thanks.

Scheme `load` is a procedure; that is, it is executed at run time.
Spock is an offline compiler, so there is no way to load Scheme code
(as opposed to JavaScript code) into a running Spock program.  As far
as I know, Spock doesn't implement `include` either, which would be a
compile-time action.

All I can suggest is that you compile them separately and then concatenate
the resulting JavaScript files.  However, if the SRFIs include macros,
those macros won't be available to your code.

Apparently you are just supposed to supply multiple files of Scheme
code on the Spock command line.

The 'load' not working makes sense now; thanks for the reminder!  It
seems odd that 'include' or something similar isn't available.

Thanks for the suggestion. I think I'll try to cobble soemthing together
using the procedural interface to spock (instead of just relying on the
command-line compile-spock, as I have been doing so far).  The 'spock'
procedure includes an 'import' option, but so far I haven't figured out
how to use it for the above purposes.  I'll have to dig a bit deeper
there.
