* module/language/tree-il/optimize.scm: Rework to just export the
optimize! procedure.
* module/language/tree-il/compile-glil.scm (analyze-lexicals): New
function, analyzes and allocates lexical variables. Almost ready to
compile now.
(codegen): Dedent.
* module/Makefile.am: Add inline.scm.
* module/language/tree-il.scm (pre-order!, post-order!): pre-order! is
new. post-order! existed but was not public. They do destructive tree
traversals of tree-il, and need more documentation. Also, add
predicates to tree-il's export list.
* module/language/tree-il/inline.scm: New file, which expands primitives
into more primitive primitives. In the future perhaps it will not be
necessary, as the general inlining infrastructure will handle these
cases, but for now it's useful.
* module/language/tree-il/optimize.scm: Move post-order! out to better
pastures.
* module/language/tree-il/optimize.scm: New module, for optimizations.
Currently all we have is resolving some toplevel refs to primitive
refs.
* module/Makefile.am: Add new module.
* module/language/tree-il.scm: Fix exports for accessors for `src'.
* module/language/tree-il/compile-glil.scm: Tweaks, things still aren't
working yet.
* module/language/scheme/amatch.scm: Remove, this approach won't be used.
* module/Makefile.am: Adjust for additions and removals.
* module/language/scheme/compile-ghil.scm: Remove an vestigial debugging
statement.
* module/language/scheme/spec.scm:
* module/language/scheme/compile-tree-il.scm:
* module/language/scheme/decompile-tree-il.scm: Add tree-il compiler and
decompiler.
* module/language/tree-il/compile-glil.scm: Add some notes.
* module/language/tree-il/spec.scm: No need to wrap expressions in
lambdas -- GHIL needs somewhere to put its variables, we don't.
* module/Makefile.am: Add tree-il sources.
* module/ice-9/compile-psyntax.scm: Adjust for sc-expand producing
tree-il in compile mode.
* module/ice-9/psyntax.scm: Switch from expand-support to tree-il for
generating output in compile mode. Completely generate tree-il -- the
output wasn't Scheme before, but now it's completely not Scheme.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/compile-ghil.scm: Strip structures using
tree-il, not expand-support.
* module/language/tree-il.scm:
* module/language/tree-il/spec.scm
* module/language/tree-il/compile-glil.scm: New language. It will compile
to GLIL, though it doesn't yet.
* module/ice-9/expand-support.scm (make-module-ref, make-lexical): Add
source arguments to these constructors.
* module/ice-9/psyntax.scm:
* module/ice-9/psyntax-pp.scm: Adapt to match, though we don't wire
everything up yet.
* module/ice-9/psyntax.scm (build-global-definition): Remove mod
argument, as it does not seem we could ever define something in another
module.
(chi-install-global): Build the define as a definition, not an
application. Doesn't matter now, but it will later.
(chi-top): Fix build-global-definition call.
* module/ice-9/psyntax.scm: Regenerated.
* module/ice-9/psyntax.scm (build-lexical-reference): Change to be a
function. Take an extra arg, the original name of the variable. If we
are compiling, make a #<lexical>, annotated with the original var name.
All callers changed.
(build-lexical-assignment): Also a function, taking also the original
var name, using build-lexical-reference to build its output.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (*mode*): New moving part, a fluid.
(sc-expand): Dynamically bind *mode* to the expansion mode.
(build-global-reference): Change to be a procedure instead of local
syntax. Import the logic about when to make a @ or @@ form to here,
from boot-9.scm. If we are compiling, build output using (ice-9
expand-support)'s make-module-ref, otherwise just making the familiar
s-expressions. (This will allow us to correctly expand in modules in
which @ or @@ are not bound, at least when we are compiling.)
(build-global-assignment): Use the result of build-global-reference. A
bit hacky, but hey.
(top-level-eval-hook, local-eval-hook): Strip expansion structures
before evalling.
* module/ice-9/boot-9.scm (make-module-ref): Remove, this logic is now
back in psyntax.scm.
* module/ice-9/compile-psyntax.scm (source): Since we expand in compile
mode, we need to strip expansion structures.
* module/ice-9/expand-support.scm (strip-expansion-structures): Remove
the logic about whether and how to strip @/@@ from here, as it's part
of psyntax now.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/compile-ghil.scm (compile-ghil): Strip expansion
structures -- for now. In the future, we might translate directly from
these structures into GHIL.
* module/ice-9/boot-9.scm (sc-expand3):
* module/ice-9/psyntax.scm (sc-expand3): Replace sc-expand with
sc-expand3, as expand3 with one argument is the same as sc-expand.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/compile-psyntax.scm:
* module/language/scheme/compile-ghil.scm: Change callers to sc-expand3
to use sc-expand.
* module/ice-9/boot-9.scm: Comment some more things.
* module/ice-9/psyntax.scm: Remove error-hook -- callers should just use
syntax-violation. Change all callers.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/boot-9.scm (and-map, or-map): Move these definitions up so
psyntax can use them.
(andmap): Remove, yay.
* module/ice-9/psyntax.scm: Remove notes about andmap, and just use
Guile's and-map -- except in cases that need the multiple list support,
in which case we have a private and-map*.
* module/ice-9/psyntax-pp.scm: Regenerated.
* libguile/macros.c (scm_macro_p): Update docs.
* module/ice-9/boot-9.scm (module-define!, module-ref): Define pre-boot
forms of these functions as well. I suspect module-add! can go soon.
(module-lookup-keyword, module-define-keyword!)
(module-undefine-keyword!) Remove these.
* module/ice-9/psyntax-pp.scm: Regenerate. Notice the difference?
* module/ice-9/psyntax.scm (put-global-definition-hook)
(get-global-definition-hook): Rework to expect first-class macros. Heh
heh.
(remove-global-definition-hook): Pleasantly, this hook can go away.
(chi-install-global): Terrorism to generate the right kind of output --
will clean up.
(chi-top): Unify definition handling for all kinds of values.
* libguile/macros.c (macro_print): Show syntax-case bindings, if present.
(macro_mark): Mark the extra two words if they're there.
(scm_make_syncase_macro, scm_make_extended_syncase_macro): OK! A new
take at the "how do we represent syncase macros in Guile" problem.
Whereas we need a disjoint type, but would like it to be compatible
with old predicates (e.g. `macro?'), and need to be able to extend
existing syntax definitions (e.g. `cond'), let's add a bit to macros to
indicate whether they have syncase macro bindings or not, and a fourth
macro type for native syncase macros.
(scm_macro_type): Return 'syntax-case for native syntax-case macros.
Note that other macro types may have syntax-case bindings.
(scm_macro_name): Return #f if the transformer is not a procedure.
(scm_syncase_macro_type, scm_syncase_macro_binding): New accessors for
the syncase macro bindings.
* libguile/macros.h: Add API for syncase macros.
* module/ice-9/boot-9.scm (module-define-keyword!): Adapt to use syncase
macros, though they are not yet used. Reorder other syncase API.
* module/ice-9/psyntax.scm (chi-expr): Fix syntax-violation invocation.
* module/ice-9/boot-9.scm:
* module/ice-9/psyntax-pp.scm:
* module/ice-9/psyntax.scm: Change syntax-dispatch to $sc-dispatch, as it
is in current psyntax. The idea is that this isn't really a public
variable, though it has to be, currently, so just obscure that fact
with an obscure name.
* module/ice-9/boot-9.scm (datum->syntax, syntax->datum): Rename from
datum->syntax-object and syntax-object->datum, following r6rs. Change
all callers. Reorder some of the other exports from psyntax.
* module/ice-9/psyntax.scm: Change datum->syntax and syntax->datum
definitions and callers.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/oop/goops.scm (define-class-pre-definition): Update for changes.
* module/ice-9/boot-9.scm (syntax-violation): Well, as long as we have to
have a function for indicating syntax errors, let's let it be a
well-thought-out one -- syntax-violation from r6rs. No more
syntax-error.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm: Replace instances of syntax-error with
syntax-violation. Implement as a scm-error to 'syntax-error, with some
nice arguments.
* libguile/modules.c (scm_module_local_variable): Allow this to be called
before modules are booted with #f as the module.
* module/ice-9/boot-9.scm (module-define-keyword!)
(module-lookup-keyword, module-undefine-keyword!): Well, if syncase
forces us to allow the keyword bindings to be partitioned from value
bindings, let's go ahead and do that in boot-9 instead of in
psyntax. A step on the way to removing `install-global-transformer'.
(sc-chi): Remove.
* module/ice-9/psyntax.scm (put-global-definition-hook):
(remove-global-definition-hook, get-global-definition-hook): Use our
new module-* functions.
(sc-chi): Remove, no longer needed.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/Makefile.am (SRFI_SOURCES): Let's finally start compiling
srfi-18.scm, what the hell.
* module/ice-9/boot-9.scm (module-bound?): module-bound? was returning
true if (not (variable-bound? (module-local-variable m v))), but
(variable-bound? (module-variable m v)). Fix to cut out on the first
variable it finds. This bug has been there for a while now.
* module/ice-9/boot-9.scm (define-macro, defmacro): Add the ability to
have a docstring.
* module/ice-9/documentation.scm (object-documentation): Remove
references to defmacro? and macro?. Since we store the transformation
procedure as the binding, we can get docs from the procedure directly.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (put-global-definition-hook):
Take the type and the value separately, so we can set the variable to
the procedure, while keeping the *sc-expander* to be the "binding
object".
(global-extend): Pass type and val separately.
* libguile/eval.c (scm_m_eval_when): Whoops, eval-when has an implicit
begin. Fix.
* module/oop/goops.scm: Syncase doesn't like definitions in expression
context, and grudgingly I have decided to go along with that. But that
doesn't mean we can't keep the old semantics, via accessing the module
system directly. So do so. I took the opportunity to rewrite some
macros with syntax-rules and syntax-case -- the former is nicer than
the latter, of course.
* module/oop/goops/save.scm: Don't define within an expression.
* module/oop/goops/simple.scm (define-class): Use define-syntax.
* module/oop/goops/stklos.scm (define-class): Use define-syntax.
* module/ice-9/boot-9.scm (define-macro): Use syntax-case to destructure
macro arguments, so we get good errors.
* module/ice-9/match.scm (defstruct, define-const-structure): Don't
unquote in the `defstruct' macro as a value in expansions.
* module/oop/goops.scm (standard-define-class): Can't define a macro with
`define', use `define-syntax' instead.
(define-accessor): Use syntax-rules. Doesn't give us much in this case.
(toplevel-define!): New helper, to let us keep GOOPS' behavior with the
new expander. Some solution that works lexically and at the toplevel
would be nice, though.
(define-method): Reimplement with syntax-rules -- soooo much nicer.
* module/oop/goops/dispatch.scm (lookup-create-cmethod): Don't define
within an expression.
* module/Makefile.am (SCHEME_LANG_SOURCES):
* module/language/scheme/expand.scm: Remove expand.scm, we don't need it
any more.
* module/ice-9/psyntax.scm (build-lambda, chi-lambda-clause): Support
docstrings with internal definitions. What are Scheme people thinking
these days?
* module/ice-9/psyntax-pp.scm: Regenerated.
* libguile/eval.h:
* libguile/eval.c (scm_m_eval_when): Define a cheap eval-when, used
before syncase has booted.
* module/Makefile.am: Reorder to put (system vm) and (system repl)
modules after the compiler, as they are not needed at runtime.
* module/ice-9/boot-9.scm: Move the eval-when earlier, to be the first
thing -- so when we recompile Guile we do so all in the '(guile)
module, not '(guile-user).
* module/ice-9/compile-psyntax.scm: Rewrite to assume that psyntax.scm
will eval-when to set its module, etc. Have everything in a let --
otherwise the `format' call is in (guile), but `target' was defined
in (guile-user). Also, write in an eval-when to the expanded file.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/networking.scm:
* module/ice-9/psyntax.scm:
* module/ice-9/r4rs.scm: Sprinkles of eval-when, for flavor.
* module/ice-9/psyntax.scm (chi-macro): It's possible for a macro
procedure to have no module, if the procedure was made before modules
were booted.
* module/ice-9/psyntax-pp.scm: Regenerated.
* configure.in: No longer output the Makefile.ins.
* module/Makefile.am: Include the contents of ice-9/, srfi/, and oop/.
* module/ice-9/Makefile.am:
* module/ice-9/debugger/Makefile.am:
* module/ice-9/debugging/Makefile.am:
* module/oop/Makefile.am:
* module/oop/goops/Makefile.am:
* module/srfi/Makefile.am: Removed.
* module/ice-9/psyntax.scm
* module/ice-9/psyntax-pp.scm
* module/ice-9/boot-9.scm (make-module-ref): We were so almost there
with what we had, sniff. The deal is that
(begin (load "foo.scm") ((@@ (foo) bar)))
would expand to
(begin (load "foo.scm") (bar))
because bar was unbound at expansion time, and make-module-ref assumed
it was like the else in a cond. But it shouldn't have, because we
/explicitly/ asked for the @@ var -- so now if we see a @ or @@, we
never drop it. @@ introduced by hygiene can be dropped if it doesn't
reference a var, though.
Practically speaking, this means tagging all modules in psyntax with
their intent: public or private (corresponding to @ or @@), hygiene
(introduced by a macro), or bare (when we don't have a module). I'm
not sure when we'd see a bare.
The implementation is complicated by the need to support the old
format and the new format at the same time, so that psyntax-pp can be
regenerated.
* module/ice-9/boot-9.scm
(make-module-ref): equal?, not eq?, when matching on module name.
(Module names don't have to come from an invocation of module-name in
this process.)
* module/ice-9/psyntax.scm (build-global-reference)
(build-global-assignment, @): Rework the format of the module in syntax
objects so that a car of #f indicates a public reference. Loading (foo
%module-public-interface) didn't guarantee that (foo) was loaded and
useful.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/compile-ghil.scm (lookup-transformer):
primitive-macro? does not exist any more.
* module/ice-9/boot-9.scm: Remove lots of debugging prints. Remove some
already-deprecated attempts to load modules from shared libraries.
* module/ice-9/psyntax.scm: If we have to create a variable for a
syntactic binding, initialize its contents to a gensym. I'd like
something more meaningful, but at least this way we can tell different
macros apart. Only warn about missing modules if modules are booted.
Chi the value part of a (set! (@ ...) ) expression -- whoops!
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/glil.scm (parse-glil): Fix an unquoting error.
* module/language/scheme/compile-ghil.scm: No need to import syncase, we
gots it. Rework compiler to expand only once, with syncase, instead of
incrementally. Fix define-scheme-transformer to work with syncase, by
not referencing bare keywords. It works!
* module/ice-9/psyntax.scm: Allow the redefinition of keywords to
variables. Otherwise we can't do (define let #f), which is totally
useful and stuff.
* module/ice-9/psyntax-pp.scm: Regenerated.
* 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.
