* module/oop/goops.scm (method): Reimplement as a hygienic macro. This
seriously took me like 6 hours to figure out. Allows for lexical
specializers: (let ((<x> ...)) (define-method (foo (arg <x>)) ...)).
* module/oop/goops/compile.scm (next-method?, compile-make-procedure):
Remove these, as `method' does it all now, hygienically.
* module/language/tree-il/compile-glil.scm: Add primcall compilers for
@slot-ref and @slot-set.
* module/language/tree-il/optimize.scm (add-interesting-primitive!): New
export. Creates an association between a variable in the current module
and a primitive name.
* module/oop/goops.scm: Rework compiler hooks to work with tree-il and
not ghil.
* 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.
* 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.
* 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/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/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/compile-ghil.scm (define-scheme-translator):
Only add an else clause if the transformer didn't have one.
* module/oop/goops.scm (min-fixnum, max-fixnum): Define at compile-time
as well.
(@slot-ref, @slot-set!): Only define transformers for these at
compile-time. Avoids loading up the compiler unnecessarily. Also, allow
for the `n' to be determined lexically, in which case we dispatch to
the primitive.
(num-standard-pre-cache, define-standard-accessor-method)
(bound-check-get, standard-get, standard-set): Rework the fixed-offset
getters and setters so that they can be computed at compile-time.
Accessors to fields with n > num-standard-pre-cache will be dispatched
to the primitive instead of within the VM.
* libguile/goops.c (scm_make): In the pre-inst `make', default
`procedure' to #f, and read a `make-procedure' instead of
`compile-env'.
* libguile/goops.h (scm_si_make_procedure): This instead of
scm_si_compile_env.
* module/oop/goops.scm (make-method): Remove this unused function. Users
should use (make <method> ...) directly.
(method): Capture `make-procedure' instead of `procedure' in the case
that the body calls a next-method. Allows for the kind of
"recompilation" that we were using before, but with closures instead of
re-entering the compiler. Type-specific compilation is still
interesting, but probably should be implemented in another way.
(initialize): Default #:procedure to #f, and
s/compile-env/make-procedure/.
* module/oop/goops/compile.scm (code-table-lookup): Just return the
cmethod, not the entry -- since the entry is now just (append types
cmethod).
(compile-make-procedure): New procedure, returns a form that, when
evaluated/compiled, will yield a procedure of one argument, the
next-method. When called with a next-method, the procedure returns an
actual method implementation. compile-make-procedure returns #f if the
body doesn't call next-method.
(compile-method): Unify to always return procedures. Much cleaner and
*much* faster in the compiled case. In the interpreted case, there
might be a slight slowdown, but if there is one it should be slight.
* module/oop/goops/dispatch.scm (method-cache-install!): Adapt to removal
of compute-entry-with-cmethod.
* libguile/objects.c (scm_apply_generic): Inline the case when the
generic is a program.
* libguile/vm-i-system.c (return): Tick when functions return.
* module/oop/goops.scm (object-eqv?, object-equal?): Remove these
historical methods.
* doc/ref/api-evaluation.texi: Fix some typos and xrefs.
* doc/ref/compiler.texi (The Scheme Compiler): Document the scheme
compiler, and start documenting the GHIL language.
* doc/ref/guile.texi (Guile Implementation): Whoops, put autoconf after
the implementation foo. Unless we want it before?
* doc/ref/history.texi (The Emacs Thesis): Fix typo.
* doc/ref/vm.texi (Environment Control Instructions): Rename offset to
index.
* module/language/ghil.scm (parse-ghil): Fix what I think was a bug --
the consumer in a mv-call shouldn't be a rest arg.
* module/language/scheme/Makefile.am (SOURCES):
* module/language/scheme/compile-ghil.scm: Rename this file from
translate.scm.
* module/oop/goops.scm:
* module/language/scheme/spec.scm: Deal with renaming.
* module/system/base/language.scm (<language>): Rework so that instead of
hardcoding passes in the language, we define compilers that translate
from one language to another. Add `parser' to the language fields, a
bit of a hack but useful for languages with s-expression external
representations but with record internal representations.
(define-language, *compilation-cache*, invalidate-compilation-cache!)
(compute-compilation-order, lookup-compilation-order): Add an algorithm
that does a depth-first search for a translation path from a source
language to a target language, caching the result in a lookup table.
* module/language/scheme/spec.scm:
* module/language/ghil/spec.scm: Update to the new language format.
* module/language/glil/spec.scm: Add a language specification for GLIL,
with a compiler to objcode. Also there are parsers and printers, for
repl usage, but for some reason this doesn't work yet.
* module/language/objcode/spec.scm: Define a language specification for
object code. There is some sleight of hand here, in the "compiler" to
values; but there is method behind the madness, because this way we
higher levels can pass environments (a module + externals pair) to
objcode->program.
* module/language/value/spec.scm: Define a language specification for
values. There is something intellectually dishonest about this, but it
does serve its purpose as a foundation for the language hierarchy.
* configure.in:
* module/language/Makefile.am
* module/language/ghil/Makefile.am
* module/language/glil/Makefile.am
* module/language/objcode/Makefile.am
* module/language/value/Makefile.am:
Autotomfoolery for the ghil, glil, objcode, and value languages.
* module/language/scheme/translate.scm (translate): Import the bits that
understand `compile-time-environment' here, and pass on the relevant
portions of the environment to the next compiler pass.
* module/system/base/compile.scm (current-language): New procedure, refs
the current language fluid, or lazily sets it to scheme.
(call-once, call-with-output-file/atomic): Refactor these bits to use
with-throw-handler. No functional change.
(compile-file, compile-and-load, compile-passes, compile-fold)
(compile): Refactor the public interface of the compiler to be generic
and simple. Uses `lookup-compilation-order' to find a path from the
source language to the target language.
* module/system/base/syntax.scm (define-type): Adapt to changes in
define-record.
(define-record): Instead of expecting all slots in the first form,
expect them in the body, and let the first form hold the options.
* module/system/il/compile.scm (compile): Adapt to the compilation pass
API (three in and two out).
* module/system/il/ghil.scm (<ghil-var>, <ghil-env>)
(<ghil-toplevel-env>): Adapt to define-record changes.
* module/system/il/glil.scm (<glil-vars>): Adapt to define-record
changes.
(<glil>, print-glil): Add a GLIL record printer that uses unparse.
(parse-glil, unparse-glil): Update unparse (formerly known as pprint),
and write a parse function.
* module/system/repl/common.scm (<repl>): Adapt to define-record changes.
(repl-parse): New function, parses the read form using the current
language. Something of a hack.
(repl-compile): Adapt to changes in `compile'.
(repl-eval): Fix up the does-the-language-have-a-compiler check for
changes in <language>.
* module/system/repl/repl.scm (start-repl): Parse the form before eval.
* module/system/repl/command.scm (describe): Parse.
(compile): Be more generic.
(compile-file): Adapt to changes in compile-file.
(disassemble, time, profile, trace): Parse.
* module/system/vm/debug.scm:
* module/system/vm/assemble.scm: Adapt to define-record changes.
* module/language/scheme/translate.scm (receive): Fix an important bug
that gave `receive' letrec semantics instead of let semantics. Whoops!
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.
