[ANN] GaUnit 0.1.6

Kouhei Sutou — 2008-10-22T13:06:27

Hi, I've released GaUnit 0.1.6: http://www.cozmixng.org/~rwiki/?cmd=view;name=GaUnit http://www.cozmixng.org/~kou/download/gaunit-0.1.6.tar.gz GaUnit is a xUnit based unit testing framework for Gauche. ! How to write? gauche.test: (test "add" 3 (lambda () (+ 1 2))) (test "sub" -1 (lambda () (- 1 2))) GaUnit: (define (test-add) (assert-equal 3 (+ 1 2))) (define (test-sub) (assert-equal -1 (- 1 2))) ! Output example A failure test derived from test/string.scm in the Gauche repository with a small change (bar -> baz): gauche.test: (test* "string-join" "foo::baz::baz" (string-join '("foo" "bar" "baz") "::")) GaUnit: (define (test-string-join) (assert-equal "foo::baz::baz" (string-join '("foo" "bar" "baz") "::"))) Here is output: gauche.test: test string-join: expects "foo::baz::baz" => got "foo::bar::baz" GaUnit: 1) Failure: test-string-join ./test-string.scm:4: (assert-equal "foo::baz::baz" (string-join '("foo" "bar" "baz") "::"))

0.8.14 FFI changes

Bill Schottstaedt — 2008-10-13T22:20:21

I moved to 0.8.14 today, and all my stuff immediately segfaults. Is there a list somewhere of the changes in this version as relates to foreign code? For example, optional arguments to a foreign function trigger a "wrong number of arguments" error. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

ANN: dyncomp 0.2.0

KOGURO, Naoki — 2008-10-11T12:19:57

Hi all. dyncomp 0.2.0 is released. dycomp is a module that enables to create C function with gauche.cgen.cise (C in S expression). This function is compiled to native code with Tiny C Compiler (http://bellard.org/tcc/), so you can create a fast function. The change from the previous version is: - Gauche module has bindings of C symbols, so different gauche modules can associate different binding to the same C symbol. - Added some macros (define-cfn, dyncomp-reset!).

Release 0.8.14

Shiro Kawai — 2008-10-07T14:35:34

Gauche 0.8.14 is available. http://practical-scheme.net/gauche/ This release is to flush out cumulative bug fixes and small improvements. Nothing particularly shiny, but the performance is also slightly improved, so you might want to upgrade. In SVN trunk there's a module parser.peg, a parser combinator library for parsing expression grammar. It is NOT included in this release. I want it be the default choice of the parser of Gauche, and not satisfied by the current implementation. You may try it from svn, but be aware that the API will be changed a lot in future. Some suggested changes are not incorporated due to the lack of the time of testing, including Tomas Stanek's suggestion of using USE_MMAP in GC. It's been over 4 years since Gauche reached 0.8. It's not that the development is slowed down; in fact a lot of code has been added or rewritten since then. These days I get more and more opportunities to use Gauche in real work, and keep adding stuff that are required in the production environ

garbage collector issues

Tomas Stanek — 2008-09-04T10:05:44

Hello, I've encountered quite large memory consumption of gauche under some circumstances. My program reads an xml document, converts it into a tree with lots of flonums (sometimes about 20000), do some work with it and continues to another document. The program also allocates few large (up to a megabyte) blocks and lot of pairs/flonums/etc during each iteration. Problem is, that it's memory consuption grows up to 200 - 300MB and never goes down. I've noticed two things... First, Scm_MakeFlonum uses SCM_NEW (not SCM_NEW_ATOMIC) for allocation of the ScmFlonum, which is pointer free. I expectd this to be a "typo". Changing SCM_NEW to SCM_NEW_ATOMIC improves the situation a bit, but not as much. Second, Boehm Weiser GC is by default configured not to use -DUSE_MMAP and -DUSE_MUNMAP flags. This way, GC doesn't ever return allocated memory to the operating system. By using -DUSE_MMAP and -DUSE_MUNMAP, memory consumption keeps around 20 - 30MB. I'm not sure why -DUSE_M[UN]MAP makes a such difference

Connecting 2 processes by a pipe

Stas Boukarev — 2008-08-28T20:55:22

How one can connect two processes by a pipe like "cat file | wc -l"? I read "9.16 gauche.process" section of the manual but still can't get it.

write-object from write vs. from display

Leonardo Boiko — 2008-07-29T15:33:04

Hi. According to gauche manual, When `write' and `display' encounter an object of a user-defined class, they call the generic function `write-object'. The same generic is called for both methods? How do I make my objects react differently to 'write' and 'display'? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

c-wrapper doesn't play with the module system?

Leonardo Boiko — 2008-07-29T02:18:04

Hi. Sorry if this is a frequent question, but I couldn't find info. I'm using ncursesw with c-wrapper like this: (use c-wrapper) (c-load-library "libncursesw") (c-include "ncursesw/curses.h") […] (use gauche.collection) From the way the module system works, I'd expect a symbol exported by both the C libs and the "collection" module to be bound to the module in the last "use" clause, but these aren't the results I get: gosh> filter # gosh> (with-module gauche.collection filter) # gosh> (filter (lambda (i) (lisp? i)) '(scheme ruby cl haskell lolcat)))) *** ERROR: wrong number of arguments: filter requires 0, but got 2 ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-c

Migrating to Subversion

Shiro Kawai — 2008-06-06T10:27:29

Hi Gauche developers, I've been procrastinating this, but SourceForge.net's CVS is getting so slow enough to convince me to finally start migrating Gauche repository to Subversion. Since Gauche repository have several packages and we have several committers, I gradually move one package at a time whenever I find time to do so. I just migrated Gauche-gl for the starter. I'm going to move small packages first, then Gauche itself. When you browse the source at the sourceforge.net webpage, check out the subversion repository first: http://gauche.svn.sourceforge.net/viewvc/gauche/ Once a package is migrated, the CVS repository will no longer be updated. I'll try to remove files from CVS repository to avoid confusions, but there may be some delay. Here's a short summary of how to access the new repository, for your convenience: THOSE WHO WANT TO GET CUTTING EDGE SOURCE ----------------------------------------- This command works in general: $ svn co https://gauche.svn.sourceforge.net/svnroot/gauche/Gau

c-wrapper: performance problem

Jens Thiele — 2008-04-10T18:52:36

Hi, I am playing around with the really nice c-wrapper module. (thanks alot!) I stumbled across a performance problem: Converting some c byte array (char*) to a u8vector is really slow. It semms the bytes are copied byte for byte in scheme. But maybe my approach is just plain wrong? Attached a test script and some profile output (using -ptime). Note: the profile output is for running the script with the line 24: (time (c-byte-array->u8vector2 (cast (c-array bytes) array))) commented out and for 50000 and 100000 bytes. #!/usr/bin/gosh ;; -*- coding: utf-8; mode: scheme -*- ;; test: performance problem with char/byte* -> u8vector (use c-wrapper) (use gauche.uvector) (use gauche.sequence) (c-load '("malloc.h")) ;; todo: really slow (define (c-byte-array->u8vector1 array) (cast array)) ;; not fast either (define (c-byte-array->u8vector2 array) (let1 data (make-u8vector (size-of array)) (for-each-with-index (lambda(i x)(u8vector-set! data i x)) array) data)) (define (main ar
