* module/ice-9/psyntax.scm (define-syntax-parameter): New toplevel form.
Will be used to implement syntax parameters, following Barzilay,
Culpepper, and Flatt's 2011 SFP workshop paper, "Keeping it Clean with
syntax-parameterize". Adds a new binding type and definition form.
Conflicts:
module/ice-9/psyntax.scm
* libguile/procprop.c
(scm_set_procedure_properties_x)[SCM_ENABLE_DEPRECATED == 1]: Pass arguments
to `scm_assq' in the right order, and check its return value with
`scm_is_true'. Reported by Mike Gran <spk121@yahoo.com>.
* module/ice-9/psyntax.scm (define-expansion-constructors)[begin-form]:
Emit a syntax-violation error for empty sequences when
--disable-deprecated.
* test-suite/tests/syntax.test (pass-if-syntax-error): Fix typo in error
message.
* doc/ref/api-data.texi (String Modification): Change
(define y "abcdefg") => (define y (string-copy "abcdefg"))
before mutating the string bound to y in the example code.
The failure path for the c-api.test had been to call the undefined function
'fail', instead of logging the error like the other tests.
* test-suite/tests/c-api.test: modified
* doc/ref/api-compound.texi (VHashes): Add missing `init' parameter in
documentation for vhash-fold and vhash-fold-right, and also improve
description.
* module/ice-9/vlist.scm (vhash-fold, vhash-fold-right): Rename formal
parameter `seed' to `init', to match documentation. Improve
docstrings.
* ramap.test: New tests.
- array-map! with noncompact arrays and more than one argument.
- array-for-each with noncompact arrays and more than two arguments.
* libguile/generalized-vectors.c (scm_c_generalized_vector_ref):
(scm_c_generalized_vector_set_x): Fix for the case in which base was
not 1, lbnd was not 0, or inc was not 1.
* test-suite/tests/arrays.test (array): Add a test. Thanks to Daniel
Llorens for the report.
* libguile/threads.c (scm_ia64_register_backing_store_base)
(scm_ia64_ar_bsp): Provide implementation of these itanium helpers on
freebsd. Thanks to Jim Pryor.
* configure.ac: Check for pthread_np.h and pthread_attr_get_np. Patch
by Jim Pryor.
* libguile/threads.c (get_thread_stack_base): Provide an implementation
for FreeBSD.
* module/web/http.scm ("Cache-Control"): Write string values using the
default val writer, to get quoting correct.
* test-suite/tests/web-http.test (pass-if-round-trip): New helper.
("general headers"): Check that cache-extensions round trip properly.
* module/web/http.scm ("Cache-Control"): Value for `max-stale' is
optional. Strict validation for value-less directives (`no-store',
etc.). String values optional for "cache-extension" directives.
* test-suite/tests/web-http.test: Value for `max-stale' is optional.
* doc/ref/api-control.texi (begin): Update to distinguish between
splicing begin and sequencing begin.
* module/ice-9/psyntax.scm (expand-expr): Add a back-compatibility shim
for `(begin)'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* test-suite/tests/syntax.test: Update to run illegal (begin) test only
if we are not including deprecated features.
* module/language/tree-il/peval.scm (singly-valued-expression?): New
helper.
(truncate-values): Use the helper.
(make-operand): Minor refactor.
(set-operand-residual-value!): Try to undo the effects of (values
FOO), if the continuation will check itself for the correct number of
values.
(peval): Fold helpers into fold-constant. Add a constant-expression?
case for (values FOO). Add a new context: "values", for contexts in
which multiple values are allowed, either because of being in a tail
context relative to a function, or because of let-values. "value" is
now for single values. Don't visit operands for "values", as their
binding form truncates to one value. Add a case to fold (values ...)
forms. Fix folding of (lambda), to process the cases in values
context instead of tail context (which could have been "value", which
would cause the procedure to truncate).
* module/ice-9/ftw.scm (file-system-fold): Fix reference to STAT instead
of ST.
(scandir)[enter?]: Change the argument name to `dir', to avoid
confusion.
[skip]: Return RESULT, not #f.
* module/ice-9/ftw.scm (scandir)[leaf]: Only add NAME when RESULT is a
pair.
[down]: Ignore RESULT.
Start with #f instead of the empty list.
* test-suite/tests/ftw.test ("scandir")["flat file"]: New test.
* doc/ref/misc-modules.texi (File Tree Walk): Update `scandir'
documentation accordingly.
* module/ice-9/deprecated.scm: Add alias for $expt. $expt was removed
in commit 6fc4d0124d but no deprecated
alias was added in ad79736c68 like for
all the other deprecated $sin, $cos, ... functions.
Suggested by Nala Ginrut <nalaginrut@gmail.com>.
* module/ice-9/ftw.scm (scandir): New procedure.
* test-suite/tests/ftw.test ("scandir"): New test prefix.
* doc/ref/misc-modules.texi (File Tree Walk): Document `scandir'.
* module/ice-9/ftw.scm (file-system-fold): Add an optional `stat'
parameter. Use it instead of `lstat'. Handle the case where (STAT child)
fails.
(file-system-tree): Likewise, and pass it to `file-system-fold'.
* doc/ref/misc-modules.texi (File Tree Walk): Update the documentation
of these functions.
This is a temporary workaround for the 2.0 stable series. The next
stable series should have an implicit `setlocale (LC_ALL, "")' call,
which will make this unnecessary.
* libguile/feature.c (progargs_fluid): Rename to...
(scm_program_arguments_fluid): ... this. Update users.
* libguile/feature.h (scm_program_arguments_fluid): New internal
declaration.
* libguile/init.c (invoke_main_func): Call
`scm_i_set_boot_program_arguments' instead of
`scm_set_program_arguments'.
* libguile/script.c (locale_arguments_to_string_list,
scm_i_set_boot_program_arguments): New functions.
(scm_compile_shell_switches): Use `locale_arguments_to_string_list'.
* libguile/script.h (scm_i_set_boot_program_arguments): New internal
declaration.
* test-suite/standalone/Makefile.am (check_SCRIPTS, TESTS): Add
`test-command-line-encoding'.
* test-suite/standalone/test-command-line-encoding: New file.
* libguile/foreign.c: Use `alignof_type' instead of `alignof'; the
latter was removed from Gnulib's <alignof.h> in
408e170e3ae81f73fb65686c5834693d89a96594 (Nov. 1 2011).
* libguile/vm-i-scheme.c: Likewise.
* module/ice-9/ftw.scm (file-system-fold, file-system-tree): New
procedures.
* test-suite/tests/ftw.test (%top-srcdir, %test-dir): New variables.
("file-system-fold", "file-system-tree"): New test prefixes.
* doc/ref/misc-modules.texi (File Tree Walk): Document
`file-system-tree' and `file-system-fold'.
* module/ice-9/session.scm: #:keyword-ify the define-module form, and
export apropos-hook.
(apropos-hook): New hook.
(apropos, apropos-fold): Run the apropos-hook.
* libguile/ports.c (scm_init_ports): Export the port fluids to Scheme,
temporarily.
* module/ice-9/boot-9.scm (fluid->parameter): Turn `current-input-port'
et al into srfi-39 parameters, backed by the exported fluids, then
remove the fluids from the guile module.
(%cond-expand-features): Add srfi-39.
* module/srfi/srfi-39.scm: Re-export features from boot-9.
* test-suite/tests/parameters.test: Add tests.
* configure.ac: Add checks for GC_gcollect_and_unmap and
GC_get_unmapped_bytes.
* libguile/gc-malloc.c (scm_realloc): GC_gcollect() if we don't have
GC_gcollect_and_unmap.
* libguile/gc.c (GC_get_heap_usage_safe): Likewise, don't
GC_get_unmapped_bytes if the function doesn't exist.
Reported by Cédric Cellier <rixed@happyleptic.org>.
* module/language/tree-il/peval.scm (truncate-values): New procedure.
(make-operand): Call `truncate-values' SOURCE.
* test-suite/tests/tree-il.test ("partial evaluation"): New tests for
multiple value truncation.
