i.e. put the extensions where they need to be, and delete
ice-9-debugger-extensions.scm.
* doc/ref/api-debug.texi (Single Stepping through a Procedure's Code):
Change mentions of (ice-9 debugging ice-9-debugger-extensions)
module to whatever is appropriate now (or just remove them).
* module/Makefile.am (NOCOMP_SOURCES): Remove
ice-9-debugger-extensions.scm.
* module/ice-9/debugger.scm (debug-trap): Move here from
ice-9-debugger-extensions.scm.
* module/ice-9/debugger/command-loop.scm ("continue", "finish",
"step", "next"): Move here from ice-9-debugger-extensions.scm.
* module/ice-9/debugger/commands.scm (assert-continuable, continue,
finish, step, next): Move here from ice-9-debugger-extensions.scm.
* module/ice-9/debugging/breakpoints.scm: Don't use
ice-9-debugger-extensions module.
* module/ice-9/debugging/ice-9-debugger-extensions.scm: Removed.
* module/ice-9/debugging/trace.scm, module/ice-9/debugging/traps.scm:
Remove more old version code.
* module/ice-9/debugging/traps.scm (guile-trap-features): Hardcoded as
'(tweaking).
* module/ice-9/debugging/ice-9-debugger-extensions.scm: Remove all
code checking for version < 1.7, and move code for versions >= 1.7
up to top level. Comment out dummy mutex definitions for now, as
I'm not sure how to rewrite them correctly for psyntax.
* module/ice-9/boot-9.scm (eval): Here at the tail of boot-9, replace
the root definition of `eval' with a procedure that will call
`compile'.
* test-suite/tests/syntax.test ("top-level define"):
("internal define"): Run unmemoization tests in the interpreter, using
primitive-eval.
* module/ice-9/boot-9.scm (@bind): Define a VM-compatible syntax
definition for this old evaluator primitive.
* test-suite/tests/dynamic-scope.test: Change the expected error
messages.
* libguile/load.h:
* libguile/load.c (scm_sys_warn_autocompilation_enabled): New primitive,
not exported. Since `load' autocompiles now, it should warn in the
same way that the bits hardcoded into C warn.
(scm_try_autocompile): Use scm_sys_warn_autocompilation_enabled.
* module/ice-9/boot-9.scm (autocompiled-file-name): New helper.
(load): Try autocompiling the argument, if appropriate. Will
autocompile files passed on Guile's command line. `primitive-load' is
unaffected.
* module/ice-9/boot-9.scm (module-name): When making MOD non-anonymous,
bind it in the `(%app modules)' name space.
* test-suite/tests/compiler.test ("psyntax")["compile in current
module", "compile in fresh module"]: New tests.
* test-suite/tests/modules.test ("foundations")["modules don't remain
anonymous"]: New test.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (chi-top)[define-form]: If a same-named
imported variable exists, take its value instead of `#f'.
* test-suite/tests/compiler.test ("psyntax")["redefinition"]: New tests.
* module/ice-9/psyntax.scm (build-lexical-var): Make our gensyms really
unique. Before, there was a chance that different lexicals could
result in the same gensym.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (source-wrap): Use decorate-source, for
clarity.
(syntax-type): When turning the RHS of (define (foo) ...) into a
lambda, decorate the resulting lambda expression with source
information, as the RHS later goes to chi-expr, which receives no
source information. Perhaps that is a bug. In any case, fixes some
source location lossage, reported by Jao.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/boot-9.scm (define-private): Remove apocyphal comment. The
FIXME would really be to remove `define-private', though...
* module/ice-9/optargs.scm (defmacro*, defmacro*-public): Fix these
macros. Thanks to Dale Smith for the report.
* module/ice-9/boot-9.scm (define-option-interface): Fix (debug-options
'full), along with other options. Thanks to Mark Weaver for the tip.
* THANKS: Update, though many more names need to be added.
* module/language/ecmascript/compile-ghil.scm (comp): Just use pmatch,
not ormatch. Now with syncase running over everything, it doesn't
matter.
* module/ice-9/boot-9.scm (false-if-exception): Avoid saving stacks
inside false-if-exception. There's probably a more general solution to
this, though. Fixes getting bogus backtraces sometimes.
* module/Makefile.am (ECMASCRIPT_LANG_SOURCES): Reorder things so that
spec comes last.
* module/ice-9/compile-psyntax.scm: Pretty-print psyntax-pp.scm, given
that we are going to compile it anyway.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/Makefile.am (ice-9/psyntax-pp.scm): Don't try autocompiling when
making psyntax-pp.scm.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-top): Only affect the compile-time
environment if modules have booted.
* libguile/vm-i-scheme.c (FUNC2): Use a signed value for the intermediate
result here. Not sure what the effect is, though.
* module/ice-9/psyntax.scm (chi-top): Toplevel definitions ensure that
variables are defined in the current module. Fixes the specific case of
guile-lib's md5.scm, which redefines + -- this code is needed so that
we don't incorrectly open-code +.
* module/language/tree-il/primitives.scm (resolve-primitives!): I think
there were some cases in which vars and names would not resolve
properly here. Fix those.
* module/ice-9/psyntax.scm (syntax-type): Remove `external-macro', not
used any more. Take an extra arg, `for-car?', indicating that we're
checking on the type of a form in the car position. In the case that
the expression is a pair, do a full recursion on the car, which allows
us to catch the fact that the car of the following form is a macro:
((@ (ice-9 optargs) let-optional) ...)
and thus the form itself should be macroexpanded.
But, since we want to distingush `lambda' from `(lambda ...)', just as
we have global and global-call, we have core to the new `core-form'.
(chi-top, chi, chi-expr, chi-body, set!): Adapt to changes to
syntax-type.
* libguile/init.c (scm_load_startup_files): Use
scm_c_primitive_load_path.
* libguile/load.c (scm_primitive_load_path): Add an optional arg,
exception_on_error, which if #f will cause primitive-load-path to just
return #f if no file is found. This is to help out the semantics of
try-module-autoload. We can't just catch misc-error, because loading
the file could raise any exception.
(scm_c_primitive_load_path): Add the extra arg to
scm_primitive_load_path.
* libguile/load.h: Adapt scm_primitive_load_path prototype.
* module/ice-9/boot-9.scm (try-module-autoload): Refactor slightly to be
clearer.
* module/ice-9/boot-9.scm (file-exists?): Change to use the stat
interface that doesn't throw exceptions.
(try-module-autoload): Simplify to take advantage of the fact that
primitive-load-path does the right thing with regards to loading
compiled files if they are available.
* libguile/read.c (flush_ws, scm_read_commented_expression)
(scm_read_sharp): Add support for commenting out expressions with #;.
(scm_read_syntax, scm_read_sharp): Add support for #', #`, #, and #,@.
* module/ice-9/boot-9.scm: Remove #' read-hash extension, which actually
didn't do anything at all. It's been there since 1997, but no Guile
code I've ever seen uses it, and it conflicts with #'x => (syntax x)
from modern Scheme.
* module/system/base/compile.scm (compile-and-load): Whoops, fix a number
of bugs here.
* module/ice-9/boot-9.scm (default-pre-unwind-handler): Since we were
tail-called by pre-unwind-handler-dispatch, we can't use
pre-unwind-handler-dispatch as a narrowing argument. Instead just
narrow by one frame.
(pre-unwind-handler-dispatch): Deprecate.
(error-catching-loop): Remove crack comment and code, and just use
default-pre-unwind-handler as our pre-unwind handler.
* module/ice-9/stack-catch.scm (stack-catch):
* module/system/repl/repl.scm (call-with-backtrace): Use
default-pre-unwind-handler directly.
* doc/ref/api-procedures.texi (Compiled Procedures): Fix for API changes.
* doc/ref/compiler.texi (Compiling to the Virtual Machine): Replace GHIL
docs with Tree-IL docs. Update the bits about the Scheme compiler to
talk about Tree-IL and the expander instead of GHIL. Remove
<glil-argument>. Add placeholder sections for assembly and bytecode.
* doc/ref/vm.texi: Update examples with what currently happens. Reword
some things. Fix a couple errors.
* libguile/vm-i-system.c (externals): Remove this instruction, it's not
used.
* module/ice-9/documentation.scm (object-documentation): If the object is
a macro, try to return documentation on the macro transformer.
* module/language/assembly/disassemble.scm (disassemble-load-program):
Fix problem in which we skipped the first element of the object vector,
because of changes to procedure layouts a few months ago.
* module/language/scheme/spec.scm (read-file): Remove read-file
definition.
* module/language/tree-il.scm: Reorder exports. Remove <lexical>, it was
a compat shim to something that was never released. Fix `location'.
* module/language/tree-il/primitives.scm (/): Fix expander for more than
two args to /.
* module/system/base/compile.scm (read-file-in): Remove unused
definition.
* module/system/base/language.scm (system): Remove language-read-file.
* module/language/ecmascript/spec.scm (ecmascript): Remove read-file
definition.
* module/ice-9/psyntax.scm (source-annotation): Return #f if
source-properties returns null.
(source-wrap): Rework a bit.
(syntax-type): Don't throw away source info for wrapped expressions.
Can has source location info, fools!
(chi-body): Correctly propagate source info for body subforms.
(syntax): Remove special case for map, it doesn't apply (ahem) for
Guile.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm: Remove references to annotation objects,
we're just going to try and use Guile's source properties now. It works
until `syntax' reconstructs output, at which point it seems we lose it.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-body): Fix a problem introduced in
dc1eed52f7, that internal syntax definitions were included in the id
lis along with value definitions. Only showed up on a second bootstrap.
Psyntax, how I love thee.
* module/ice-9/psyntax-pp.scm
* module/ice-9/threads.scm: Move syntax definitions before the procedures
that use them, and rewrite as hygienic macros since they are so much
nicer that way. Fixes the thread tests.
* module/ice-9/boot-9.scm (cond): Implement srfi-61; most of the code is
from the SRFI itself. Yuk.
(%print-module, make-modules-in, %app, (%app modules))
(module-name): Syncase needs to get at the names of modules, even at
anonymous modules. So lazily assign gensyms as module names. Name %app
as (%app), but since (%app modules) is at the top of the module
hierarchy, name it ().
* module/ice-9/psyntax.scm: When building tree-il, try to name lambdas in
definitions and in lets.
(let, letrec): Give more specific errors in a couple of cases.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syntax.test: More work. Many exceptions have different
messages than they used to, many more generic; we can roll this back to
be faithful to the original strings, but it doesn't seem necessary to
me.
* module/language/tree-il.scm (tree-il->scheme):
* module/ice-9/psyntax.scm (build-conditional): Attempt to not generate
(if #f #f) as the second arm of an if, but it doesn't seem to be
successful.
* module/ice-9/psyntax-pp.scm (syntax-rules): Regenerate.
* test-suite/tests/syntax.test (exception:unexpected-syntax): Change
capitalization.
("unquote-splicing"): Update test.
("begin"): Add in second arms on these ifs, to avoid the strange though
harmless expansion of `if'.
(matches?): New helper macro.
("lambda"): Match on lexically bound symbols, as they will be
alpha-renamed.
* module/ice-9/psyntax.scm (chi-lambda-clause): Strip the docstring
before passing it on to the continuation.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/eval.test (exception:failed-match): New exception, for
syntax-case failed matches.
("evaluator"): Fix macro-as-parameter tests. They pass now :)
* module/ice-9/boot-9.scm (guile-user): Move the `compile' autoload to
the guile-user module. Remove reference to compile-time-environment.
* module/language/scheme/compile-ghil.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/optimize.scm:
* module/system/base/compile.scm:
* test-suite/tests/compiler.test: Remove definition of and references to
compile-time-environment. While I do think that recompilation based on
a lexical environment can be useful, I think it needs to be implemented
differently. So for now we've lost nothing if we take it away, as it
doesn't work with syncase anyway.
* module/ice-9/psyntax.scm (chi-install-global, syntax-case): Fix a
couple of cases in which bare datums were passed to output
constructors.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/spec.scm (scheme): Clean up the #:compilers
list.
* module/language/tree-il/compile-glil.scm (flatten): Fix call to
`length' in call/cc compiler.
* libguile/vm-i-system.c:
* libguile/vm-engine.h (ASSERT_BOUND): New assertion, that a value is
bound. Used by local-ref and external-ref in paranoid mode.
* module/ice-9/boot-9.scm (and, or, cond, case, do): Since we are
switching to use psyntax as the first pass of the compiler, and perhaps
soon of the interpreter too, we need to make sure it expands out all
forms to primitive expressions. So define expanders for these derived
syntax forms, as in the R5RS report.
* module/ice-9/psyntax-pp.scm: Regenerate, with core forms fully
expanded.
* module/ice-9/psyntax.scm (build-void): New constructor, for making
undefined values.
(build-primref): Add in a hack so that primitive refs in the boot
module expand out to toplevel refs, not module refs.
(chi-void): Use build-void.
(if): Define an expander for if that calls build-conditional.
* module/language/scheme/compile-tree-il.scm (compile-tree-il): Use let*
so as not to depend on binding order for the result of
(current-module).
* module/language/scheme/spec.scm (scheme): Switch over to tree-il as the
primary intermediate language. Not yet fully tested, but at least it
can compile psyntax-pp.scm.
* module/language/tree-il/analyze.scm (analyze-lexicals): Arguments don't
count towards a function's nlocs.
* module/language/tree-il/compile-glil.scm (*comp-module*, compile-glil):
Define a "compilation module" fluid.
(flatten-lambda): Fix a call to make-glil-argument. Fix bug in
heapifying arguments.
(flatten): Fix number of arguments passed to apply instruction. Add a
special case for `(values ...)'. If inlining primitive-refs fails,
try expanding into toplevel-refs if the comp-module's variable is the
same as the root variable.
* module/language/tree-il/optimize.scm (resolve-primitives!): Add missing
src variable for <module-ref>.
* test-suite/tests/tree-il.test ("lambda"): Fix nlocs counts. Add a
closure test case.
* module/ice-9/boot-9.scm (delay): Define `delay' in terms of
make-promise.
* module/ice-9/psyntax-pp.scm (compile): Regenerated with a fully
compiled Guile, so that the gensym numbers are the same.
* module/language/tree-il/compile-glil.scm: Add some notes about what
needs doing to catch up to the old compiler.
* module/ice-9/psyntax.scm (build-lambda, build-let, build-named-let)
(build-letrec): Actually pass along the original ids to tree-il
constructors.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/tree-il.scm: Add fields in <lambda>, <let>, and
<letrec> for the original variable names.
* module/language/tree-il/compile-glil.scm (compile-glil): Adapt for new
make-lambda arg.
* module/ice-9/psyntax.scm (build-letrec, build-let, build-lambda)
(build-named-let): Take extra args for the original names of the
gensyms. Not used yet. Callers adapted.
* module/ice-9/psyntax-pp.scm: Regenerated.
