* module/ice-9/r4rs.scm:
* module/ice-9/boot-9.scm (%load-verbosely, assert-load-verbosity)
(%load-announce, %load-hook, load): Move these from r4rs.scm to
boot-9.scm.
* module/ice-9/compile-psyntax.scm: Update to work with
syncase-in-boot-9.
* module/ice-9/psyntax-pp.scm: Recompiled with syncase-in-boot-9.
* module/ice-9/boot-9.scm
(eval-when): Remove, as syncase is going to handle this one for us.
(sc-expand, sc-expand3, sc-chi, install-global-transformer)
(syntax-dispatch, syntax-error, annotation?, bound-identifier=?)
(datum->syntax-object, free-identifier=?, generate-temporaries)
(identifier?, syntax-object->datum, void, andmap): Oh, ugly of uglies:
add these exciting definitions to the main environment. Hopefully we
can pull them back out soon.
(make-module-ref, resolve-module): Stub these out, as a replacement for
expand-support.
(%pre-modules-transformer): Define to sc-expand, so that we are using
syncase from the very start.
(defmacro, define-macro): Define in terms of syntax-case.
(macroexpand, macroexpand-1): Remove, there should be a different way
to get at this -- though perhaps with the same name.
(make-module): Make sc-expand the default module-transformer.
(process-define-module): Issue a deprecation warning when using ice-9
syncase.
(primitive-macro?): Remove, no meaning...
(use-syntax): Deprecate.
(define-private, define-public, defmacro-public): Rework in terms of
syntax-rules.
* module/ice-9/syncase.scm: Gut, as syncase is provided by core now.
* 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/system/repl/command.scm:
* module/system/repl/common.scm:
* module/system/repl/repl.scm:
* module/system/vm/debug.scm:
* module/system/vm/trace.scm: Change #:use-syntax to #:use-module, as
that's really what we want to do.
* 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/language/scheme/expand.scm (re-annotate, expand): A couple of
speculative cases for dealing with syncase better -- but all of this
code is likely to go.
* 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.
* meta/guile-tools: Instead of fixing scripts I should have been fixing
the script runner.
* module/scripts/compile.scm:
* module/scripts/snarf-guile-m4-docs.scm: Fix to take rest args.
* meta/guile-tools: We can't use srfi-1, because on a fresh checkout
the srfi-1 shlib isn't built yet. Bummer.
* meta/uninstalled-env.in: Fix up the DYLD lines for BSDen.
* module/scripts/snart-guile-m4-docs.scm: Fix expected arguments.
* 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.
* meta/guile-tools: Changed to be a scheme script. Instead of looking for
executables in a "scripts dir", we just look for modules in (scripts),
and load the modules directly.
* module/Makefile.am:
* module/scripts/: Move the scripts into module/ so they can be compiled.
Rename scripts from `foo' to `foo.scm'.
* libguile/Makefile.am: Invoke the snarf->texi code via guile-tools.
* configure.in:
* .gitignore: Update for changes.
* module/language/ghil.scm (unparse-ghil): Fix unparsing of quasiquoted
expressions.
* module/language/ghil/spec.scm (join): Define a joiner for GHIL.
* module/language/scheme/compile-ghil.scm (cenv-ghil-env): Expand the
definition of a CENV so it can have an actual ghil-env, if available.
(compile-ghil): Return the actual ghil env in the cenv.
* module/system/base/compile.scm (compile-file): Rewrite. `output-file'
is now a keyword argument, along with the new kwargs `env' and `from'.
We now allow exceptions to propagate up, and instead of printing the
output file to the console, we return a string corresponding to its
location.
(compile-and-load): Use read-and-compile.
(compile-fold): Thread around the cenv as well. Return all three
values.
(find-language-joint, read-and-compile): New exciting helpers. The idea
is that compiling a file should be semantically equivalent to compiling
each expression in it, one by one. Compilation can have side effects,
e.g. affecting the current language or the current reader. So what we
do is find a point in the compilation path at which different
expressions of a given language can be joined into one. Expressions
from the source language are compiled to the joint language, then
joined and compiled to the target.
(compile): Just return the first value from compile-fold.
* module/system/base/language.scm (language-joiner): New optional field.
* scripts/compile: Rework for changes to compile-file.
* module/system/base/compile.scm: Expect compile passes to produce three
values, not two. The third is the "continuation environment", the
environment that can be used to compile a subsequent expression from
the same source language. For example, expansion-time side effects can
set the current module, which would be reflected appropriately in the
continuation environment.
* module/language/assembly/compile-bytecode.scm:
* module/language/bytecode/spec.scm:
* module/language/ecmascript/compile-ghil.scm:
* module/language/ghil/compile-glil.scm:
* module/language/glil/spec.scm:
* module/language/objcode/spec.scm:
* module/language/scheme/compile-ghil.scm:
* module/system/base/compile.scm: Update compile passes to return a
continuation environment.
* We cache callees in each module, and keep a list of modified
('tainted') modules, which is used to reconstruct the callers
database incrementally.
* `procedure-callers' now returns an a-list, keyed by module name.
* module/system/xref.scm (ensure-callers-db): OK! Since we can see the
same variable twice, e.g. in different modules, keep a unified hash of
seen vars and modules. Prevents duplicates in procedure-callers.
* module/system/xref.scm (program-callee-rev-vars): It's possible to get
duplicates when combining callees of inner procedures, so ignore dups.
Quadratic, boo.
* libguile/extensions.h: Define a scm_t_extension_init_func.
* libguile/frames.c:
* libguile/instructions.c:
* libguile/objcodes.c:
* libguile/programs.c:
* libguile/vm.c: Register extension init funcs. Should play nicer with a
static Guile, in addition to working on Darwin with non-default
installation prefixes without munging DYLD_LIBRARY_PATH.
* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm: Use load-extension.
* module/oop/goops.scm (method-source): Don't throw an error if this
method has no source.
(method-formals): New generic function, the complement of
method-specializers for introspection.
* module/system/xref.scm (procedure-callers): Rework to calculate the
callers of a *variable*, not of a value. This is because the
module-observers only get fired when the module changes, not with the
variables change values. Also accept either a variable, a symbol
(resolved in the current module), or a modname . symname pair.
* 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/system/xref.scm (hacky-procedure-callees): Add a
procedure-callees implementation for procedures with source, that
currently does nothing. Not sure what to do, going into the future.
* module/language/ghil/compile-glil.scm (codegen): Push a program's
source locations before copying external args to heap -- perhaps fixes
(program-source p 0) for some programs.
* module/language/glil/decompile-assembly.scm (decompile-load-program):
Take another arg, the object vector. Emit <glil-bind> and <glil-unbind>
correctly. Properly unparse properties. Just have to deal with source
locations now.
* module/language/glil/decompile-assembly.scm: A first pass at an
assembly->glil decompiler. Works for a small subset of programs.
* module/Makefile.am (GLIL_LANG_SOURCES):
* module/language/glil/spec.scm (glil): Add the decompiler.
