* module/ice-9/boot-9.scm (module-name): Return '(guile) before the
module system is booted, for syncase's benefit. Defer redefinition
until the module system is booted.
* module/ice-9/psyntax.scm (put-global-definition-hook): Only set a
variable if it's unbound.
* module/ice-9/psyntax.scm: Regenerated.
* module/ice-9/boot-9.scm: Define a version of module-add! for psyntax,
before modules are booted.
* module/ice-9/psyntax.scm: Remove a warning, and rename a variable.
Initialize a new variable to 'sc-macro, though it will have no effect.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/expand-support.scm (strip-expansion-structures): If, when
producing @/@@ forms, we find that an @@ variable is not bound in its
module, just serialize the symbol. This bends hygiene, in that it can
introduce a global (but not lexical) reference in the expanded module,
but it seems necessary to not produce (@@ (foo) else) in forms like
((@@ (foo) cond) ((test then) ((@@ (foo) else) bar))).
* module/ice-9/boot-9.scm (peek, pk, warn): Move these helpers up to the
top. I like them!
(load-compiled): Don't define within an if, syncase doesn't like that.
* module/ice-9/psyntax.scm (syntax-type): Handle a new type, module-ref.
Like external-macro, it also has a procedure as a binding.
(chi-expr): module-ref forms -- that is to say, (@ (foo ...) bar) -- as
expressions they are global references, but with respect to a specific
module.
(@, @@): Define module-ref syntax handlers.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/syncase.scm: Mark as primitive syntax so we don't clobber
their definitions.
The reason I'm doing things like this is so as to support (set! (@@ ...)
...) sensibly, which will be the next patch.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (syntax-type): Look up the type of the car of
a form relative to its module, if it is a syntax object. Fixes hygiene
wrt modules and private macros.
* module/ice-9/syncase.scm (sc-macro): Add a comment.
* module/system/base/pmatch.scm: The big test case: just export pmatch,
not ppat too.
* libguile/eval.h:
* libguile/eval.c (error_unbound_variable, error_defined_variable):
Move these prototypes up earlier.
(scm_m_at, scm_m_atat): New functions, provide the @ and @@
functionality. Moved here from defmacros because they are
"special", inasmuch as syncase doesn't really understand them in
interpreted code.
* module/ice-9/boot-9.scm (@, @@): Don't define as defmacros, as
defmacros have to actually return source now.
* module/ice-9/expand-support.scm (strip-expansion-structures): Enable
@/@@ substitution.
* module/ice-9/psyntax-pp.scm: Recompile.
* module/ice-9/psyntax.scm: Since syntax objects are quotable, make the
module field the module name, not the module itself. Scope the operand
of global calls appropriately. Thread modules through syntax-dispatch
destructuring. Houston, we have hygiene.
* module/ice-9/syncase.scm: Adapt to module / module-name changes.
* module/ice-9/compile-psyntax.scm: No more expansion-eval-closure.
* module/ice-9/expand-support.scm (strip-expansion-structures): Only @@
names whose module is not the current module. Actually @@ serialization
is disabled for this commit, just to get this one in and keep things
working.
* module/ice-9/psyntax-pp.scm: Recompiled.
* module/ice-9/psyntax.scm (put-global-definition-hook)
(get-global-definition-hook): Instead of going through that stupid
getprop/putprop interface, let's just inline Guile-specific code here.
(build-global-reference, build-global-assignment): Fix a bug where the
module and public? were switched, which happily allowed things to
compile. (We reintroduce a similar bug above in expand-support.)
(lookup): Add a module argument.
(global-extend): Adapt for put-global-definition-hook invocation.
(syntax-type): Lookup with mod. Return mod even for lexicals and
define-form -- why not.
(chi-top, fluid-let-syntax, syntax, set!): Lookup with mod. Wrap with
mod.
* module/ice-9/syncase.scm (expansion-eval-closure)
(current-eval-closure, env->eval-closure): OK! So the idea is: module
hygiene is syncase's business, not ours. So lose the eval-closure
fluid. Also, eval closures are so 1990s.
(sc-macro): But, we have to take the module from the env, sadly. In the
future this will be different.
Remove the rest of the eval-closure bits. Enable source reporting,
while we're debugging.
* module/language/scheme/compile-ghil.scm (lookup-transformer): Adapt for
eval closure fluid changes.
* libguile/debug.h:
* libguile/debug.c (scm_procedure_module): New procedure, returns the
module that was current when the given procedure was defined. Used by
syncase to scope free identifiers.
* module/ice-9/psyntax-pp.scm: Recompiled.
* module/ice-9/psyntax.scm: Thread the module through the syntax
expansion. This is harder than it would appear because in many places
the different components of syntax objects are destructured.
* module/ice-9/syncase.scm (guile-macro): Adapt to new signature for
syntax transformer functions.
* module/ice-9/psyntax.scm: Now that we have gone through the
intermediate step (in which both representations of syntax-object had
to coexist), change all callers to make-syntax-object to pass the third
argument, and restore the define-structure definition of syntax
objects.
* module/ice-9/psyntax-pp.scm: Recompile.
* 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.
