similar in use to `use-modules'.
Example: (use-syntax (ice-9 syncase)) will 1. load the module
(ice-9 syncase), and, 2. install the procedure `syncase' as eval
transformer.
(internal-use-syntax): New procedure.
(process-define-module): Use `internal-use-syntax'.
19971027 and adapt it to the current readline interface.
* boot-9.scm (top-repl): Only enable readline if not using the
Emacs interface; Only use repl prompt when using the readline port
from repl-read. (We don't want to see it when calling `read'.)
* boot-9.scm (remove-hook!): Parenthesis bug.
nonblocking through the use of scm_internal_select.
* emacs.scm: Removed use of nonblocking.scm.
* gwish.scm, gtcl.scm: Removed. tcltk.scm has made these
obsolete.
cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
(libpath.h, versiondat.h): Replaced dependency on Makefile with
dependencies on $(srcdir)/Makefile.in
$(top_builddir)/config.status in order to avoid circularity.
* configure.in (GUILE_LIBS): New variable. Contains libraries
which libguile needs to be linked with. Substituted into
libpath.h.
* threads.m4 (threads_package): Don't add $LDFLAGS and $LIBS to
$cy_cv_threads_libs.
* ltconfig, ltmain.sh, config.sub, config.guess: Updated.
New automake: 1.3
* Makefile.in, aclocal.m4, configure: Regenerated.
* README: Mention new version numbers on libtool and automake.
(make-thread, begin-handler): Use this handler. The most
important effect of this is that signals get unmasked.
Previously, when a signal was thrown signals remained masked
(signals get masked when a signal is taken) which influenced other
threads.
ioext.c (%read-line): Return a cons of the input line and its terminator.
fports.c, genio.c, genio.h, ports.c, ports.h: Change fgets methods
to return the string length as well as its contents.
* configure.in: AC_CHECK_FUNCS: add "system".
* simpos.c (scm_system): always define: use sysmissing if not
available. Check for HAVE_SYSTEM instead of _Windows (does
Windows lack system or does it have an unusable one?).
Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
Let the argument be optional: if not supplied, call system(NULL).
* ports.c (scm_close_port): relax the type check from OPPORTP to
PORTP; closing a closed port is allowed.
out to interact badly with the Emacs support and the Tcl/Tk
support. It's not a high enough priority at the moment to be
worth fixing. I'm leaving the other readline support in, though.
* readline.scm: New module.
* boot-9.scm (repl-reader): New function.
(scm-style-repl): Call repl-reader, instead of doing the reading
ourselves. Remove repl-report-reset; it was never used for
anything.
(top-repl): If we've got the readline primitives, then redefine
repl-reader to use them.
If we've got the readline primitives, import the readline module.
expect-strings to fix the => syntax under the new regex system.
(top): include regex module in define-module statement.
* (error-catching-loop): new local variable "interactive". if
#f, abort terminates the process.
(set-batch-mode?!, batch-mode?): new closures, defined in
error-catching-loop. the names are from scsh.
* boot-9.scm (struct-layout): Use `vtable-index-layout' instead of
`0'.
1997-10-02 Mikael Djurfeldt <mdj@nada.kth.se>
* boot-9.scm (struct-printer, make-struct-printer,
set-struct-printer-in-vtable!, *struct-printer*): Removed.
(record-type-vtable, make-record-type): Don't use make-struct-printer.
(record-type-vtable): User fields "prpr" (printer is no longer a
user field).
(record-type-name, record-type-fields): Decreased slot index by
one; Use `vtable-offset-user'.
* boot-9.scm: Split off modules into separate, autoloadable files.
This reduces startup time from 10.5s to 5.5s (user cpu).
* calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
string-fun.scm: New files, containing stuff that used to be in
boot-9.scm.
* Makefile.am (ice9_sources): List new files here, for
distribution and installation.
* Makefile.in: Regenerated.
