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.
* module/ice-9/getopt-long.scm: #:keywords in the define-module block.
(option-spec): Define as a srfi-9 record instead of playing macro
games with boot-9 records.
* module/ice-9/format.scm (format): When DESTINATION is #f, use a
Unicode-capable output string port.
* test-suite/tests/format.test ("format basic output")["default to
Unicode-capable port"]: New test.
* module/ice-9/psyntax.scm (quasiquote): Import new definition from
upstream psyntax, to allow unquote and unquote-splicing to take
multiple arguments.
(unquote, unquote-splicing): Adapt to not require a particular syntax
form.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-top): When adding to the toplevel
environment at compile-time, default to undefined variables, not
variables defined to #f.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/boot-9.scm (module-add!): Add a new pre-modules version
of this function, so we can add variables the environment, not just
values.
(module-define!): Use module-add!.
* module/ice-9/format.scm (format): Test to make sure an argument is a
number before applying `inf?' and `nan?' to it. Formerly, format
would call `inf?' and `nan?' on arguments that might be either a
number or a string, although those predicates should ideally throw an
exception when applied to non-number objects.
* libguile/hashtab.c: Fix remaining vector hash table support.
* module/ice-9/session.scm (apropos-fold): Use a hash table instead of a
vector for the completions.
* module/ice-9/format.scm (format): Move the port and output-col to let*
vars, again removing a set!. We will probably move more state vars to
the let*, to let the procedures exist in a more fixed-point style.
* module/ice-9/format.scm (format): Remove the need to save a copy of
the incoming arguments, because they are available as local
variables. Do the check early for the format-string actually being a
string.
* module/ice-9/format.scm (format): Add port and format-string as formal
arguments. Seems also to have triggered a reindent. Formally
deprecate omitting the port, as it's usually an error.
* test-suite/tests/format.test ("format basic output")
("format basic output", "~{ iteration"): Fix up tests that omitted the
destination port.
* module/ice-9/format.scm (format:symbol-case-conv)
(format:iobj-case-conv): Remove these exports, they were not used.
(format:expch): Remove this one, though it was used.
(format:floats, format:complex-numbers, format:radix-pref): Inline
these "configuration variables" into the format body.
* module/ice-9/futures.scm (%futures): Change from a list to a queue.
(register-future!, process-futures, touch): Adjust accordingly.
(unregister-future!): Remove.
