* module/ice-9/psyntax.scm (lookup): Reflow comment.
(chi-top, syntax): Add comments about mod for lookup.
(set!): Lookup the identifier in the module attached to its syntax
object. In the (set! MACRO foo) case, after expanding the macro, chi
the resulting expression with the empty wrap, as syntax-type
does. Seems to fix the case where the expansion references
lexically-bound variables.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syncase.test: Add a bunch of tests.
* module/ice-9/boot-9.scm (*repl-stack*): Instead of repl-level, have a
stack.
(batch-mode?): Change to poke the stack.
* module/ice-9/deprecated.scm (set-batch-mode?!): Update deprecation
method.
* module/system/repl/common.scm (repl-prompt): Update to poke
*repl-stack* to get the level.
* module/system/repl/repl.scm (start-repl): Bind *repl-stack*
appropriately.
* module/system/repl/common.scm (<repl>): Add inport and outport fields
and accessors.
(make-repl): Add optional "debug" argument. Bind inport and outport to
the current inport and output ports at the time of repl creation.
(repl-read): Read from the repl inport.
(repl-print): Write to the repl outport.
* module/system/repl/command.scm (read-datum, read-line, meta-command):
Respect repl-inport, and bind the outport of meta-commands to the repl
outport.
* module/ice-9/boot-9.scm (exit-hook): Move up with the other hooks.
(top-repl): Don't install handlers for SIGFPE, SIGILL, SIGSEGV, or
SIGBUS, as they will have no effect.
* module/ice-9/psyntax.scm (underscore?): New helper, like ellipsis?.
(syntax-case): Treat the _ pattern as a matches-all pattern,
disallowing it from the keyword list. Another well-thought part of the
R6RS.
($sc-dispatch): Dispatch _ patterns.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syncase.test ("_ is a placeholder"): Add a test.
* module/ice-9/boot-9.scm (export!): New syntax, as export is to
module-export!, export! is to module-replace!. I thought that taking
up the name `replace' would be presumptuous, hence the name mismatch.
* module/ice-9/r6rs-libraries.scm (library): Calculate not only
re-exports, but replacements as well.
* module/rnrs/io/ports.scm (open-string-input-port):
(open-string-output-port): Ensure that the ports are unicode-capable
by binding %default-port-encoding to "UTF-8".
* module/ice-9/boot-9.scm (ensure-batch-mode!): Remove comment about
restoring signals, and that behavior, as it was making popen.test
hang. I should investigate further, but instead I'm just going to hope
that this fixes it.
* module/ice-9/r6rs-libraries.scm (resolve-r6rs-interface): To avoid having to
create alias libraries for all the SRFIs, we simply ignore the name
components, so (srfi :n foo bar) will resolve to (srfi :n).
* module/ice-9/psyntax.scm (build-lexical-assignment)
(build-global-assignment): Maybe name the RHS.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/boot-9.scm (catch, with-throw-handler, throw): Rework to
use set! instead of define! so that we get names.
* libguile/backtrace.h (scm_the_last_stack_fluid_var)
* libguile/backtrace.c (scm_init_backtrace): No more
scm_the_last_stack_fluid_var. The replacement is to resolve
`the-last-stack' in (ice-9 stack-catch).
(scm_backtrace_with_highlights): Accordingly, instead of backtracing
the last stack, backtrace the current stack.
* libguile/throw.h:
* libguile/throw.c:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_internal_stack_catch): Deprecate this
function.
* module/ice-9/save-stack.scm (the-last-stack): Move here from boot-9.
* module/ice-9/debug.scm:
* module/ice-9/debugger.scm: Use (ice-9 save-stack) for the-last-stack.
* module/ice-9/deprecated.scm (the-last-stack): Add deprecated shim.
* module/ice-9/boot-9.scm (false-if-exception): Use syntax-rules. Don't
muck with the-last-stack, it is going away. Remove a later comment
about the-last-stack.
* module/ice-9/psyntax.scm (set!): Handle variable transformers; though,
they cannot produce definitions.
(make-variable-transformer): New procedure.
(identifier-syntax): Allow the R6RS form that makes variable
transformers.
* module/ice-9/psyntax-pp.scm: Regenerated.
* doc/ref/r6rs.texi (R6RS Incompatibilities): Remove letrec* item, and
add set! restriction.
* module/ice-9/boot-9.scm:
* module/ice-9/scm-style-repl.scm (handle-system-error): Move here from
boot-9.
* module/ice-9/deprecated.scm (handle-system-error): Keep a deprecated
wrapper in the root environment.
accessors.
* module/rnrs/conditions.scm (define-condition-type): The generated
accessors should be condition accessors, which know how to unpack a
compound condition; these can then delegate to the appropriate record
accessors.
* test-suite/tests/r6rs-conditions.test: New test case to verify above.
* module/ice-9/boot-9.scm (before-signal-stack): Remove. We're moving
away from using the-last-stack, so this backup copy is not much use.
(top-repl): Don't bother saving a before-signal-stack.
* module/ice-9/debugger/command-loop.scm (debugger-handler): No need to
restore here either.
* module/ice-9/boot-9.scm (*repl-level*): New global fluid, moved here
from (system repl common).
(batch-mode?): Reimplement in terms of *repl-level*.
(ensure-batch-mode!): A replacement for set-batch-mode?!.
* module/ice-9/deprecated.scm (set-batch-mode?!): Deprecate.
* module/ice-9/popen.scm (open-process): Use ensure-batch-mode!.
* module/ice-9/scm-style-repl.scm (error-catching-loop): Override
ensure-batch-mode!.
* module/system/repl/common.scm: Remove *repl-level*.
