Re: Community service

[Nala Ginrut]

Hi there!
I believe this is meaningful for my Ragnarok project. Though it's a
multi-protocols generic server, it contains HTTP, and provides
Guile-template naturally.
If I released a stable version someday (maybe few months later), I'll
start a new project of web-framework just like Guile-on-Rails or
something alike. Which may based on Ragnarok as an inner server.
At that time your site may provide more interesting things for Guilers.

Well, but the only bad thing is, I don't know how long I'll spend on
implementing them...
I pray to finish that as soon as possible in case I've done it and you
down it...

This seems to be like , which is fixed by
commit 5de0053178b4acc793ae62838175e5f3ab56c603.

Could you apply this patch and confirm?  Alternatively, you can try a
tarball from .

Ports in Guile are both binary and textual.  This allows for things like:

  scheme@(guile-user)> (use-modules (rnrs io ports))
  scheme@(guile-user)> (define (string->enc s e)
 (let ((p (with-fluids ((%default-port-encoding e))
(open-input-string s
   (get-bytevector-all p)))
  scheme@(guile-user)> (string->enc "hello" "UTF-16BE")
  $1 = #vu8(0 104 0 101 0 108 0 108 0 111)
  scheme@(guile-user)> (string->enc "hello" "ISO-8859-3")
  $2 = #vu8(104 101 108 108 111)
  scheme@(guile-user)> (use-modules (rnrs bytevectors))
  scheme@(guile-user)> (utf16->string $1)
  $3 = "hello"

You may also want to look at ‘string->pointer’ in (system foreign).

Does it answer your question?

Thanks,

It does, by virtue of mixed binary/textual ports (see my previous
message.)

When checking the new patched version of Guile, there is "check-guile"
script in root of Guile source directory. After "./configure" and "make",
you can execute this script "./check-guile" and it will display many
information like this:
  .
  .
  Running vlist.test
  Running weaks.test
  Running web-http.test
  Running web-request.test
  Running web-response.test
  Running web-uri.test

  Totals for this test run:
  passes: 34414
  failures:   2
  unexpected passes:  0
  expected failures:  30
  unresolved test cases:  578
  untested test cases:1
  unsupported test cases: 9
  errors: 0

This script write a log file, check-guile.log. In above case, there is 2
failures. you can grep like this:
  $ grep ^FAIL check-guile.log
  FAIL: gc.test: gc: Lexical vars are collectable
  FAIL: threads.test: mutex-ownership: mutex with owner not retained (bug
#27450)

If you find errors, use ^ERROR instead of ^FAIL.
