* module/ice-9/vlist.scm (vlist-fold-right): Avoid `vlist-reverse' and
instead `vlist-ref' individual elements. The result is about twice
faster. Thanks Andy for suggesting it indirectly. :-)
* module/ice-9/boot-9.scm (map, for-each): Implement in Scheme instead
of C. There are boot versions before `cond' is defined.
(map-in-order): Define this alias here instead of in evalext.h.
* libguile/eval.c: Stub out the map and for-each definitions to just
call into Scheme.
* libguile/evalext.c: Remove map-in-order definition.
* module/srfi/srfi-1.scm: Replace all calls to map1 with calls to map.
(map, for-each): Define implementations here, in Scheme, instead of in
C.
* test-suite/tests/eval.test (exception:wrong-length, "map"): Update the
expected exception for mapping over lists of different lengths.
* libguile/srfi-1.h:
* libguile/srfi-1.c: Remove map and for-each definitions. Remove the
bit that extended the core `map' primitive with another method: the
right way to do that is with modules.
* module/ice-9/r4rs.scm (call-with-input-file, call-with-output-file): Rewrite
with call-with-values.
(with-input-from-file): use call-with-input-file.
(with-output-to-file, with-error-to-file): use call-with-output-file.
Update docstrings to make clear that multiple values may be yielded.
* module/ice-9/psyntax.scm (free-id=?): For identifiers that are
resolved to the toplevel, check that the variables that they would
resolve to are equal, instead of simply checking that the symbolic
identifier names are equal. Allows keywords to be bound, renamed,
exported, excluded, etc.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (chi-when-list): Just match symbolically
instead of lexically, so as not to tie the meaning of eval-when to the
bindings of eval, load, compile, and expand.
* module/ice-9/boot-9.scm (while): Specify the return value as #f under
normal conditions, #t under (break), and arg... under (break arg...).
* test-suite/tests/syntax.test ("while"): Test.
* doc/ref/api-control.texi (while do): Document.
* module/ice-9/control.scm (reset, shift): Add implementations of these
operators from Wolfgang J Moeller, derived from implementations by
Oleg Kiselyov.
(reset*, shift*): Procedural variants.
* test-suite/tests/control.test ("shift and reset"): Add tests,
originally from Oleg Kiselyov.
* doc/ref/api-evaluation.texi (Compilation): Add discussion of
--fresh-auto-compile.
* doc/ref/scheme-scripts.texi (Invoking Guile): Add --fresh-auto-compile
option.
* NEWS: Add entry.
* libguile/load.c: Define %fresh-auto-compile.
(scm_primitive_load_path): Use it here.
(scm_init_load_should_auto_compile): Init from GUILE_AUTO_COMPILE env
var, with a value of "fresh".
* module/ice-9/boot-9.scm (load-in-vicinity): Auto-compilation cache is
stale if %fresh-auto-compile is true.
* module/ice-9/command-line.scm (compile-shell-switches): Parse out
--fresh-auto-compile.
* module/ice-9/command-line.scm: New module for parsing Guile's command
line, ported from script.c. Includes local eval-string implementation
to make `guile -c 1' faster, by not having to load the compiler.
* module/Makefile.am: Add to build.
* module/ice-9/boot-9.scm (define-inlineable): Moved here from SRFI-9.
* module/srfi/srfi-9 (define-inlinable): Removed here.
* doc/ref/api-procedures.texi (Inlinable Procedures): Add subsection
about `define-inlinable'.
* module/ice-9/psyntax.scm (fx+, fx-, fx=, fx<): Given our lame lack of
an inliner, inline these manually with identifier syntax.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (with-syntax): Allow definitions in the body,
as seems to be suggested by the R6RS.
* test-suite/tests/syncase.test ("with-syntax"): Add test.
* module/ice-9/psyntax-pp.scm: Regenerate.
* libguile/r6rs-ports.c (scm_get_string_n_x): Implement `get-string-n!'
in C for efficiency.
* libguile/r6rs-ports.h: Add prototype for this function.
* module/ice-9/binary-ports.scm: Export `get-string-n!'.
* module/rnrs/io/ports.scm (get-string-n): Implement based on
`get-string-n!'.
Export both `get-string-n!' and `get-string-n'.
* module/rnrs.scm: Also export these.
* test-suite/tests/r6rs-ports.test (8.2.9 Textual input): Add a few
tests for `get-string-n' and `get-string-n!'.

* module/ice-9/boot-9.scm (while): Report an error if `continue' is
passed one or more arguments. Previously, it would report an error if
`(continue arg rest ...)' was found within the `while', but not if
`continue' was found bare and later applied to one or more arguments,
e.g. `(apply continue (list arg rest ...))'.
* 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.
* 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.
* 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.
* 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.
* module/ice-9/binary-ports.scm: New module.
* module/Makefile.am: Add to makefile.
* module/rnrs/io/ports.scm: Re-export bindings from (ice-9 binary
ports). This will allow the compiler to not pull (rnrs) into its
included module set.
* module/ice-9/boot-9.scm (the-scm-module): Make it its own public
interface.
* test-suite/tests/modules.test ("foundations")["the-root-module",
"the-scm-module"]: New tests.
* module/ice-9/boot-9.scm (load-in-vicinity): New helper, loads a file
relative to a path.
(load): Turn into a macro that captures the name of the source file
being expanded, and dispatches to load-in-vicinity. Referencing
`load' by bare name returns a closure that embeds the current source
file name.
* libguile/backtrace.c (scm_print_exception): Add C binding for
print-exception, which dispatches to whatever is defined in Scheme.
(boot_print_exception): Add initial binding, replaced later in
Scheme.
* module/ice-9/boot-9.scm: Expect there to already be a print-exception
binding.
* module/ice-9/boot-9.scm (set-exception-printer!, print-exception):
Define an extensible exception-printing mechanism.
Also register printers for all keys thrown by Guile.
Inspired by a patch by Andreas Rottmann.
* libguile.h:
* libguile/Makefile.am:
* libguile/deprecated.h:
* libguile/deprecated.c:
* libguile/init.c:
* libguile/properties.c:
* libguile/properties.h: Deprecate the "primitive properties"
interface. It was only used to implement object properties, and that
is no longer the case.
* module/ice-9/boot-9.scm (make-object-property): Reimplement just in
terms of weak hash tables, and make threadsafe.
* NEWS:
* doc/ref/api-utility.texi: Update.
* module/ice-9/getopt-long.scm (fatal-error): New helper. For errors
that come from the user -- i.e., not the grammar -- we will handle our
own error printing and call `exit' rather than relying on the root
catch handler. This is more friendly to the user than a Scheme
backtrace.
(parse-option-spec, process-options, getopt-long): Call `fatal-error'
as appropriate.
* test-suite/tests/getopt-long.test (pass-if-fatal-exception): New
helper, checks that a certain key was thrown to, and that suitable
output has been printed on an error port.
(deferr): Change to expect a 'quit key instead of 'misc-error. Update
exceptions to not match the beginning of the string, as that will be
the program name. Update tests to use pass-if-fatal-exception.
