Gauche-0.8.1 is a maintainance release of Gauche-0.8.
Gauche-0.8 release announce is cited here:
* *New Features*
o Auxiliary scripts: Gauche now installs a few scripts
that help to build and install extension packages. The
gauche-package script handles download, unpacking,
configuration, building and installation in one command
invocation. See the description of "Using extension
packages" section of the manual. (NB: this feature is
still new and may have problems, but hey, let's give a
try.) A couple of auxiliary scripts, gauche-cesconv and
gauche-install can be called from Makefile. They don't
have documentation yet, but try --help option for these
scripts.
o Module util.match: Andrew Wright's match macro is
bundled. It is modified to handle Gauche's object system.
* *Improvements*
o A couple of performance tuning were done for I/O and
loading Scheme files.
o Now you can subclass <error> class as well as
<exception> class to define your own error type. A new
built-in macro guard, which is SRFI-34 compliant, can be
used to handle errors selectively. Eventually the errors
from built-in procedures will have more structured
exception hierarchy.
o New built-in system procedures: sys-lchown, sys-realpath.
o Built-in sort routines now have stable versions,
stable-sort and stable-sort!.
o New built-in macro: let/cc.
o New built-in keyword procedures: delete-keyword, delete-keyword!.
o New built-in regexp procedure: rxmatch-num-matches.
o Module file.util: new procedures: file-is-symlink?,
file->string, file->string-list, file->list, file->sexp-list.
o Module gauche.net: documented the previously
experimental procedures: socket-send, socket-sendto,
socket-recv, socket-recvfrom, socket-getpeername,
socket-getsockname. Now these are official procedures.
o Module gauche.process: process-command wasn't exported,
even though it was documented.
o Module gauche.test: you can control whether the error in
the test procedure is reported or not by an envioronment
variable GAUCHE_TEST_REPORT_ERROR and a global variable
*test-report-error*. Useful to find a problem during testing.
o Module www.cgi: new procedure cgi-get-metavariables;
allows the user routine to take metavariables via
cgi-metavariables parameter, so that cgi scripts can be
easily modularized.
o Module gauche.parseopt: support of "optional
option-argument" is added.
o Module gauche.array: homogeneous numeric array types are added.
o Module text.html-lite: added frame-related tags.
