* module/Makefile.am:
* module/ice-9/eval-string.scm: New module, for use in implementing the
scm_c_eval_string_from_file_line suggestion.
* test-suite/Makefile.am:
* test-suite/tests/eval-string.test: New tests.
* doc/guile.1: Added the current month and year, Guile version
descriptive text, and the text GNU to the title.
Updated the nroff formatting commands for the SYNOPSIS and OPTIONS
sections to what 'man' prescribes. See 'man(1)', 'man(7)', and
'man-pages(7)'.
Corrected grammar, spelling, and capitalization (for example,
'scheme' to 'Scheme').
Vertical white-space was non-standard (two lines between some
sections, one space between others). Changed this to the standard
one empty line before each section heading, and added dots (a single
period on a line) before every section heading (.SH) so that
maintainers will find the readability unchanged.
Added white space to follow the 'groff' recommendation of starting
every sentence on its own line, and breaking sentences at
punctuation.
Corrected an error in description of the info command.
Added the missing option '--no-debug', and the short switches '-h'
and '-v'.
Changed the description of the environment variable
GUILE_LOAD_COMPILED_PATH so that it references the Guile variable
`%load-compiled-path' instead of the variable `%load-path'.
Updated the copyright to include 2011.
* libguile/guile-snarf.in (modern_snarf): Allow programs to specify
multiple initialization actions on a single line. This makes it
possible for C programs to define multiple subrs with a single macro
invocation.
* test-suite/standalone/test-guile-snarf: Enable more tests.
* module/system/repl/command.scm (terminal-width): New parameter that
will use the true terminal width if unset.
(backtrace, locals): Default to (terminal-width).
(width): Simplify.
This meta-command allows one to set the default number of columns
that output from ,backtrace and ,locals shall occupy.
* doc/ref/scheme-using.texi (Debug Commands): document ,width
* module/system/repl/command.scm (*width*): new var
(backtrace, locals): use *width* in optarg
(width): new meta-command
* module/system/repl/repl.scm (read-comment, read-scheme-line-comment)
(read-scheme-datum-comment): New helpers.
(meta-reader): Take a language instead of a reader. If we have a
nonwhitespace char, first check to see that it's a comment, and if so,
read it off and loop.
(prompting-meta-read): Call meta-reader with the lang.
* module/system/repl/repl.scm (flush-leading-whitespace): Rename from
next-char.
(meta-reader): Use flush-leading-whitespace.
(run-repl): Use flush-to-newline after the evaluation, which seems to
be the same as what we did before.
* libguile/read.c (scm_i_scan_for_encoding): If possible, just use the
read buffer for the encoding scan, and avoid seeking. Fixes
`(open-input-file "/dev/urandom")', because /dev/urandom can't be
seeked backwards.
* module/ice-9/boot-9.scm (module-use-interfaces!): Fix up to prevent
duplication in the use list of multiple incoming interfaces.
* test-suite/tests/modules.test ("module-use"): Add tests.
This fixes a problem with R6RS's `import' in particuliar: when importing
a subset of a library/module, the interface created for that purpose
inherits the name of the module it is derived from. The low-level
primitives that are used for importing would then disregard earlier
imports from the same module.
An example for this bug can be seen with the following library
definition:
(library (test-guile2)
(export foo)
(import (only (rnrs base) define)
(only (rnrs base) error))
(define (foo . args)
#t))
In the above, the import of `define' would be disregarded when `error'
is imported, thus leading to a syntax error, since `(foo . args)' is
treated as an application, since the binding of `define' would be not
present.
* module/ice-9/boot-9.scm (module-use!): Remove the filtering of the
existing imports of the module by name; a check for identity is
already done beforehand.
(module-use-interfaces!): Filter the existing imports by identity
instead of filtering them by their names.
* doc/ref/api-foreign.texi (Foreign Libraries): Make it clear that the
LIBRARY argument of `dynamic-link' should not contain an extension.
(Foreign Functions): Add cross-reference from `load-extension' to
`dynamic-link'. Typeset file names and module names correctly.
* test-suite/tests/popen.test (open-input-pipe no-duplicate): Pass
"read REPLY" command instead of "read" to the subshell, for improved
portability. In particular, it is needed when /bin/sh is dash.
(open-output-pipe no-duplicate): Pass "exec guile [...]" instead of
"guile [...]" to the subshell, to ensure that the subshell will not
run guile as a subprocess while holding a duplicate of STDIN, which
would cause this test to fail. This is needed when /bin/sh is dash.
* test-suite/tests/popen.test (open-input-pipe no-duplicate): Pass
"read REPLY" command instead of "read" to the subshell, for improved
portability. In particular, it is needed when /bin/sh is dash.
(open-output-pipe no-duplicate): Pass "exec guile [...]" instead of
"guile [...]" to the subshell, to ensure that the subshell will not
run guile as a subprocess while holding a duplicate of STDIN, which
would cause this test to fail. This is needed when /bin/sh is dash.
* libguile/read.c (scm_read_scsh_block_comment): Use `scm_getc' instead
of `scm_get_byte_or_eof'.
* test-suite/tests/reader.test ("read-options")["position of SCSH block
comment"]: New test.
* configure.ac: Strip anything beyond `-I' from $GUILE_CFLAGS so that
`guile-2.0.pc' does not export them to the user. Reported and fixed
by Bruno Haible <bruno@clisp.org>.
* module/system/repl/repl.scm (flush-all-input): New helper.
(prompting-meta-read): Flush all input on a read error, as we could be
within some expression or a string or something.
* module/ice-9/boot-9.scm (scm-error-printer): Allow #f for rest args,
interpreting it as '(). Fixes regexp throws, which are of the form:
(regular-expression-syntax "make-regexp" "Invalid preceding regular expression" #f ("?.*"))
* module/ice-9/psyntax.scm (chi-top-sequence): Manually inline
eval-if-c&e into its two call sites; I found it hard to understand
otherwise. If the mode is just 'e, defer expansion of definitions and
expressions until the end, so that they can be expanded in a context
of all syntax expanders defined in the sequence.
* module/ice-9/psyntax.scm (chi-top-sequence): Pull chi-top into the
body of this toplevel begin expander. This will let us do r6rs
toplevel expansion correctly.
(chi-top): Remove.
(macroexpand): Dispatch to chi-top-sequence directly.
* libguile/i18n.c (scm_nl_langinfo)[GROUPING]: Consider negative numbers
like `CHAR_MAX'. Reported by David Fang <fang@csl.cornell.edu>.
Fix suggested by Bruno Haible <bruno@clisp.org>.
* libguile/hashtab.c (scm_c_register_weak_gc_callback): New private
helper, arranges for a C function to be called with a SCM as an
argument, as long as the argument is reachable by GC.
(scm_make_weak_key_hash_table)
(scm_make_weak_value_hash_table)
(scm_make_doubly_weak_hash_table): Register a weak GC callback to
vacuum_weak_hash_table.
* libguile/gc.c (scm_gc): No need to take a mutex here. Don't run the
hook, the hook will run itself.
(scm_c_register_gc_callback): New private helper, registers a callback
the next time GC happens.
(system_gc_callback): Guile's internal callback that runs
scm_after_gc_c_hook, which itself queues a call to the after-gc-hook.
(scm_storage_prehistory): Queue up a call to system_gc_callback.
* module/web/uri.scm:
* module/web/server.scm (call-with-output-string*):
(call-with-output-bytevector*): Local procs to output to strings or
bytevectors, *and then close the port*. We can't make this change in
call-with-output-string because it would be incompatible.
* module/web/uri.scm (call-with-encoded-output-string, decode-string)
(uri-decode)
* module/web/server.scm (call-with-encoded-output-string): Use the new
helpers.
* module/ice-9/popen.scm (open-pipe*): Hack around the lack of an
after-gc hook, and pump the pipes guardian here in the procedure that
adds to the guardian.
* libguile/hashtab.c (vacuum_weak_hash_table): New helper, goes through
the entirety of a weak hash table, vacuuming dead entries.
(scm_hash_fn_create_handle_x): If when adding to a weak hash table, we
would trigger a rehash, vacuum the table first. The weak_bucket_assoc
would have only caught dead entries within one bucket.
Without this patch, the following code leaks:
(let lp ()
(call-with-output-string
(lambda (port)
(display "foo" port)))
(lp))
* module/rnrs/base.scm (define-proxy): New macro.
(raise, condition, make-error, make-assertion-violation,
make-who-condition, make-message-condition, make-irritants-condition):
Use it.
* doc/ref/autoconf.texi (Using Autoconf Macros): Switch example to use
PKG_CHECK_MODULES.
* doc/ref/libguile-linking.texi (A Sample Guile Main Program): Likewise,
and change from configure.in to configure.ac, and recommend
autoreconf.
