* module/ice-9/local-eval.scm: New module (ice-9 local-eval) which
exports `the-environment', `local-eval', and `local-compile'.
* libguile/debug.c (scm_local_eval): New C function that calls the
Scheme implementation of `local-eval' in (ice-9 local-eval).
* libguile/debug.h (scm_local_eval): Add prototype.
* doc/ref/api-evaluation.texi (Local Evaluation): Add documentation.
* test-suite/tests/eval.test (local evaluation): Add tests.
* test-suite/standalone/test-loose-ends.c (test_scm_local_eval):
Add test.
* module/Makefile.am: Add ice-9/local-eval.scm.
Based on a patch by Mark H Weaver <mhw@netris.org>.
* module/ice-9/boot-9.scm:
* module/ice-9/psyntax.scm (syntax-module, syntax-local-binding)
(syntax-locally-bound-identifiers): After boot, move these definitions
to a new (system syntax) module.
* module/ice-9/psyntax-pp.scm: Regenerate.
* doc/ref/api-macros.texi: Add some words about syntax-module and
friends being in (system syntax).
* module/ice-9/boot-9.scm (current-filename): Canonicalize the path, so
that the result is independent of the current directory, and so
that `dirname' can traverse up the file system, as in the
add-to-load-path example.
(add-to-path): Remove. The eval-when semantics make this macro too
tricky to explain -- people will start using it on other path-like
things, in lexical contours, whereas it only really makes sense with
load-like paths at the toplevel.
* doc/ref/api-evaluation.texi (Loading): Fix link to load-with-path
docs, and remove add-to-path docs.
* module/ice-9/boot-9.scm (syntax-local-binding): New binding.
* module/ice-9/psyntax.scm: Locally define a fluid that holds the
"transformer environment". with-transformer-environment calls a
procedure with the transformer environment, or raises an error if
called outside the extent of a transformer. Bind
transformer-environment in expand-macro.
(resolve-identifier): Backport this helper from master.
(syntax-local-binding): New procedure to return binding information of
a bound identifier (a lexical, macro, a pattern variable, a displaced
lexical, a global, or some other form).
* module/ice-9/psyntax-pp.scm: Regenerate.
* doc/ref/api-macros.texi (Syntax Transformer Helpers): Add docs for
syntax-local-binding, and syntax-source, and move some other
descriptions to this new section.
Based on a patch by Julian Graham <julian@member.fsf.org>
* libguile/values.c, libguile/values.h (scm_c_value_ref): New function.
* doc/ref/api-control.texi (Multiple Values): Add documentation.
* test-suite/standalone/test-scm-values.c: New test program.
* test-suite/standalone/Makefile.am: Add test-scm-values test.
* doc/ref/libguile-snarf.texi (Function Snarfing): The s_FOO binding
isn't deprecated; no need to warn people to stop using it. Thanks to
Peter Brett for the hint.
* module/ice-9/ftw.scm (errno-if-exception): New macro.
(file-system-fold): Add an `error' parameter. Wrap `opendir' and STAT
calls in `errno-if-exception' and call ERROR when appropriate.
(file-system-tree): Provide an `error' procedure. Return #f when
FILE-NAME is unreadable.
(scandir): Provide an `error' procedure.
* test-suite/tests/ftw.test (%top-builddir): New variable.
(make-file-tree, delete-file-tree): New procedures.
(with-file-tree): New macro.
("file-system-fold"): Update tests to add an `error' procedure.
["ENOENT", "EACCES", "dangling symlink and lstat", "dangling symlink
and stat"]: New tests.
("file-system-tree")["ENOENT"]: New test.
("scandir")["EACCES"]: New test.
* doc/ref/misc-modules.texi (File Tree Walk): Update `file-system-fold'
documentation.
* libguile/deprecated.h: Mark scm_immutable_cell and
scm_immutable_double_cell as being SCM_DEPRECATED, not SCM_API.
Deprecate SCM_ASRTGO.
* libguile/deprecated.c (scm_i_deprecated_asrtgo): New support
procedure.
* doc/ref/api-control.texi (Handling Errors): Remove ASRTGO docs.
* doc/ref/api-modules.texi (Modules): Add subsection for "Modules and
the File System". Move "Included Guile Modules" to the end. Move
"Module System Reflection" after "Variables", as we need to know about
variables. Flesh out "Module System Reflection" a bit, with docs on
module-ref, module-variable, and other bindings. General editing.
* 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.
* 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.
* 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/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.
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.
* 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'.
