* module/system/repl/repl.scm (start-repl): If the debugging ports are
unbound, bind them to the current i/o ports. Allows errors within
with-output-to-foo / with-input-from-foo to be sensibly debugged.
* module/system/repl/repl.scm (prompting-meta-read): Use
call-with-error-handling.
* module/system/vm/debug.scm (call-with-error-handling): Add case for
#:on-error 'pass. Have the catch handler return the unspecified value.
* module/system/repl/repl.scm (prompting-meta-read): Catch and print
read errors here, returning unspecified in that case.
(start-repl): Don't enable the debugger while reading expressions.
Adapt with-backtrace to with-error-handling.
* module/system/vm/debug.scm (run-debugger, debugger-repl): No need to
take a stack, the frames vector is sufficient.
(call-with-error-handling, with-error-handling): New public utilities.
Notably they do not poke the-last-stack.
* module/ice-9/boot-9.scm (find-versioned-module): Perform a stable sort on
version numbers of matched libraries; eliminate extra path separator in
library file path.
* module/ice-9/boot-9.scm (module-filename, set-module-filename!): Add a
new field to modules, the filename that is associated with the module.
For debugging purposes.
(process-define-module): Parse out a #:filename argument.
(make-module, make-autoload-interface): Adapt to module-constructor
change.
(define-module): Init module-filename from (current-source-location).
* module/ice-9/format.scm (format:parse-float): Accept a number, and
when stringifying the number, first convert to inexact.
* test-suite/tests/format.test ("~f fixed-point"): Add exact rational
test.
* module/ice-9/psyntax.scm (chi-install-global, chi-macro)
(eval-local-transformer): Now that we handle module hygiene through
syntax objects, there is no more need to record the current module
when installing syntax transformers.
* module/ice-9/psyntax-pp.scm: Regenerated (trickily).
* libguile/_scm.h: Bump objcode version for macro representation change.
* libguile/macros.c (scm_macro_transformer): Adapt to change in macro
representation.
* module/ice-9/psyntax.scm (chi-macro): Instead of assuming that output
of a macro should be scoped relative to the module that was current
when the macro was defined, allow the module information associated
with the syntax object itself to pass through unmolested. Fixes bug
29860.
(datum->syntax): Propagate the module of the identifier through to the
new syntax object, so that datum->syntax preserves module hygiene in
addition to lexical hygiene.
(include, include-from-path): Refactor to plumb though the hygiene
information from the filename instead of the `include', allowing
hygiene from the original caller of include-from-path to propagate
through.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syncase.test ("macro-generating macro"): Add test for
bug 29860.
* module/ice-9/psyntax.scm (syntax-type): Add some comments about source
locations. In calls to chi-macro, pass the source location
information. Propagate source location information when unpacking
syntax objects.
(chi-macro): Add a comment about source locations. Decorate output
introduced by the macro with the source location of macro use.
* module/ice-9/psyntax-pp.scm: Regenerate.
Fixes bug #29817.
* module/system/vm/debug.scm (frame->module): Actually bind frame-local
variables to values in the new anonymous module. Setting settable vars
should work too :)
* module/system/repl/common.scm (*repl-level*): New public fluid.
(repl-prompt): If *repl-level* is a positive integer, add it to the
prompt.
* module/system/repl/repl.scm (start-repl): The `lang' argument is now
optional, and defaults to (current-language). New kwargs level and
welcome; level defaults to 0, or 1+ the existing level, and the
welcome is a boolean, true if level is 0. Parameterize *repl-level*
during the dynamic extent of this repl. Also, parameterize
the-last-stack to #f for the duration of this repl.
* module/system/vm/debug.scm (frame->module, debugger-repl): Stubs of a
recursive repl implementation. The idea is to be a repl in the lexical
context of the error; but it would be nice to be able to operate in
the module of the proc too, for example to export bindings. Hmm.
* module/system/base/compile.scm:
* module/system/base/language.scm (*current-language*, current-language):
Move this fluid and thunk down to (system base language).
* module/rnrs/bytevectors.scm:
* module/rnrs/io/ports.scm: Add #:version (6) to these modules.
* module/6/rnrs.scm: Add versions to the import specs for bytevectors
and ports.
* module/ice-9/psyntax.scm (define-expansion-accessors): New helper, to
define accesors for a particular expansion data structure. Use it
later to define lambda?, lambda-meta, and set-lambda-meta!.
(maybe-name-value): Update to work with the newly defined accessors.
(build-global-reference, build-let, build-named-let, build-letrec):
Re-enable naming of procedures.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/r6rs-libraries.scm (library): Unwrap the `for' sub-form
during export resolution the same way that `import' does.
* test-suite/tests/rnrs-libraries.test ("implicit phasing"): New test
prefix and tests.
* module/sxml/sxml-match.ss (sxml-match1): Invoke ESCAPE via
`call-with-values'.
* test-suite/tests/sxml-match-tests.ss ("test multiple value returns"):
New test.
* module/sxml/match.scm: Mention the modification.
