* module/ice-9/psyntax.scm (make-syntax-object): As an intermediate step
to adding modules to syntax objects, replace the definition of
syntax-object as a structure with an expanded-out definition that has
(1) a constructor that takes 2 or 3 arguments, and (2) a predicate that
works with vectors of length 3 or 4. I couldn't just redefine
make-syntax-object, for example, because these are internal
definitions, and we can't have duplicate bindings in a letrec.
* module/ice-9/Makefile.am: Replace annotate.scm with expand-support.scm.
* module/ice-9/annotate.scm: Removed; subsumed into expand-support.scm.
* module/ice-9/compile-psyntax.scm: Strip out expansion structures before
writing to disk.
* module/ice-9/expand-support.scm: New file. Provides annotation support,
and other compound data types for use by the expander. Currently the
only one that is used is the toplevel reference, <module-ref>, but we
will record lexicals this way soon.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (build-global-reference)
(build-global-assignment): Instead of expanding out global references
as symbols, expand them as <module-ref> structures, with space to
record the module that they should be scoped against. This is in
anticipation of us actually threading the module info through the
syntax transformation, so that we can get hygiene with respect to
modules.
* module/ice-9/syncase.scm: Replace eval-when. Since sc-expand will give
us something that isn't Scheme because we put the <module-ref>
structures in it, strip that info whenever we actually do need scheme.
* module/language/scheme/compile-ghil.scm (lookup-transformer): Strip
expansion structures here too.
* module/language/scheme/expand.scm (language): Swap annotate for
expand-support. But this file will die soon, I think.
* module/system/xref.scm: Implement procedure-callers, as the inverse of
procedure-callees, with a cache invalidated by changes in modules.
* module/ice-9/boot-9.scm (module-use!): Don't poke module observers when
module-use! is called for an already-used module.
* module/ice-9/annotate.scm (set-annotation-stripped!): Fix prototype to
correspond to what syncase needs.
* module/ice-9/psyntax.scm (strip-annotation): Use `if', not `when', for
portability.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/annotate.scm (deannotate/source-properties): Version of
deannotate that sets source properties on the resulting expressions.
* module/ice-9/syncase.scm (sc-macro, syncase): Annotate expressions
before they go into syncase, and deannotate/source-properties when they
come out. The upshot is that syncase now understands source
information, yay!
* module/ice-9/psyntax.scm (build-annotated): New helper, used by the
output constructors.
(build-application, build-conditional, build-lexical-reference)
(build-lexical-assignment, build-global-reference)
(build-global-assignment, build-global-definition, build-lambda)
(build-primref, build-data, build-sequence, build-let)
(build-named-let, build-letrec, build-lexical-var): Use
build-annotated, so we produce annotated source if we have source
information.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/annotate.scm (<annotation>): Slightly more concise
printing.
(annotate): Don't create annotations if we have no source info.
* module/ice-9/psyntax.scm (annotation?): Remove this definition, as we
now provide annotation support.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/syncase.scm: Use (ice-9 annotate).
* module/language/scheme/expand.scm (eval-when): Define the eval-when
transformer.
* module/ice-9/boot-9.scm (eval-when): Replace eval-case with eval-when.
Eval-when is *much* simpler, and more expressive to boot. Perhaps in
the future we'll get 'visit and 'revisit too.
* module/ice-9/deprecated.scm (eval-case): Provide mostly-working
deprecated version of eval-case.
* module/ice-9/boot-9.scm (defmacro, define-macro): Relax condition: we
can make defmacros that are not at the toplevel now. But in the future
we should replace this implementation of defmacros with one written in
syntax-case.
(define-module, use-modules, use-syntax): Allow at non-toplevel.
(define-public, defmacro-public, export, re-export): Don't evaluate at
compile-time, I can't see how that helps things. Allow `export' and
`re-export' at non-toplevel.
* module/ice-9/getopt-long.scm:
* module/ice-9/i18n.scm:
* module/oop/goops.scm:
* module/oop/goops/compile.scm:
* module/oop/goops/dispatch.scm: Switch to use eval-when, not
eval-case.
* module/language/scheme/compile-ghil.scm (eval-when): Replace eval-case
transformer with eval-when transformer. Sooooo much simpler, and it
will get better once we separate expansion from compilation.
* module/language/scheme/expand.scm (quasiquote): Hm, expand quasiquote
properly. Not hygienic. Syncase needed.
(lambda): Handle internal defines with docstrings propertly.
* module/language/scheme/expand.scm: New module, implements a separate
expansion phase, not interleaved with compilation.
* module/language/scheme/amatch.scm: Helper for expand.scm, it's pmatch
with support for annotated source.
* module/ice-9/Makefile.am (SOURCES): Add annotate.scm to build list --
early on because it will be used in the compiler.
* module/ice-9/annotate.scm: Fix the printer, default to unstripped
(whatever that is), and add a deannotator.
* module/system/base/compile.scm (call-with-compile-error-catch): Fix for
new representation of source locations.
* module/Makefile.am (SCHEME_LANG_SOURCES): Add amatch and expand.
* module/system/vm/program.scm (program-arguments): New function, used by
procedure-arguments.
* module/ice-9/session.scm (procedure-arguments): New exported function,
returns an alist describing the given procedure.
* module/ice-9/getopt-long.scm (define-one-option-spec-field-accessor,
define-one-option-spec-field-modifier): Eval-case for `load-toplevel'
as well so that the interpreter can load this module.
* module/ice-9/getopt-long.scm (option-spec-fields): Enclose in a
`(load-toplevel compile-toplevel)' `eval-case'.
(define-one-option-spec-field-accessor,
define-one-option-spec-field-modifier): Enclose in a
`compile-toplevel'-only `eval-case'.
* module/ice-9/boot-9.scm (default-pre-unwind-handler): Rename from
default-lazy-handler.
(pre-unwind-handler-dispatch): Rename from lazy-hadler-dispatch.
(error-catching-loop): Adjust caller.
* module/system/repl/repl.scm (default-pre-unwind-handler): Remove this
definition, in favor of the default one in boot-9.
(default-catch-handler): Don't do a vm-backtrace, as we will soon be
relying on core machinery to do that for us.
(call-with-backtrace): Start a new stack for the thunk.
(with-backtrace): Macro version of call-with-backtrace.
(start-repl): Use with-backtrace for brevity. Start a stack with #t as
the tag instead of repl-eval, because all traces of repl-eval are gone
after it does a tail-call.
* module/ice-9/debugger.scm:
* module/ice-9/debugging/traps.scm:
* module/ice-9/stack-catch.scm: Adapt to s/lazy/pre-unwind/ in
boot-9.scm.
Moved ice-9/ and oop/ under module/, with the idea being that we have
only scheme under module/. Adjusted configure.in and Makefile.am
appropriately. Put oop/ at the end of the compilation order.
