* 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.
because of conflict between `syntax-case' transformer binding and
`(rnrs syntax-case)' hierarchical namespace module binding.)
* module/6/rnrs.scm: New file.
* module/Makefile.am: Add 6/rnrs.scm to RNRS_SOURCES.
* module/rnrs/arithmetic/6/fixnums.scm: Fix missing imports;
(fixnum-width, greatest-fixnum, least-fixnum): Redefine these as
zero-argument procedures; Fix argument mismatches in several functions.
* test-suite/Makefile.am: Add tests/r6rs-arithmetic-fixnums.test to
SCM_TESTS.
* test-suite/tests/r6rs-arithmetic-fixnums.test: New file.
library.
* module/Makefile.am: Add rnrs/arithmetic/6/fixnums.scm and
rnrs/arithmetic/6/flonums.scm to RNRS_SOURCES.
* module/rnrs/6/base.scm: (div-and-mod, div0, mod0, div0-and-mod0): New
functions; this `div' implementation is not quite right, but we'll come
back to it later.
* module/rnrs/arithmetic/6/fixnums.scm: New file.
* module/rnrs/arithmetic/6/flonums.scm: New file.
* test-suite/Makefile.am: Add tests/r6rs-arithmetic-flonums.test to
SCM_TESTS.
* test-suite/tests/r6rs-arithmetic-flonums.test: New file.
* module/Makefile.am: Add rnrs/6/eval.scm to RNRS_SOURCES.
* module/rnrs/6/eval.scm: New file
* test-suite/Makefile.am: Add tests/r6rs-eval.test to SCM_TESTS.
* test-suite/tests/r6rs-eval.test: New file.
* module/rnrs/6/lists.scm: Import syntax is
`(only (import-set) id-1 ...)', not `(only (import-set) (id-1 ...))';
use `rename' form as wrapper instead of creating separate custom
interface on SRFI-1.
* module/rnrs/6/exceptions.scm: Remove dependency on (rnrs syntax-case);
rewrite guard and guard0 in using syntax-rules in terms of syntax-case.
* module/rnrs/6/syntax-case.scm: Add syntax-violation implementation.
(rnrs records procedural).
* module/rnrs/6/conditions.scm: Fix export of
make-implementation-restriction-violation; remove dependency on
(rnrs syntax-case); remove redundant function
compound-condition-components; rewrite define-condition-type using
syntax-rules instead of syntax-case.
* module/rnrs/records/6/procedural.scm: Remove serious-condition?,
violation? and assertion-violation? predicates, since they're not true
condition predicates.
* test-suite/Makefile.am: Add tests/r6rs-conditions.test to SCM_TESTS.
* test-suite/tests/r6rs-conditions.test: New file.
libraries.
* module/Makefile.am: Add rnrs/6/mutable-pairs.scm and
rnrs/6/mutable-strings.scm to RNRS_SOURCES.
* module/rnrs/6/mutable-pairs.scm: New file.
* module/rnrs/6/mutable-strings.scm: New file.
* module/rnrs/6/exceptions.scm: (guard0, guard): New syntax.
* module/rnrs/records/6/procedural.scm: (r6rs-raise-continuable): Can't
use `raise' here because it's exported by (rnrs exceptions); use plain
old `throw' instead.
* test-suite/Makefile.am: Add tests/r6rs-exceptions.test to SCM_TESTS.
* test-suite/tests/r6rs-exceptions.test: New file.
