* module/ice-9/boot-9.scm (file-exists?): Change to use the stat
interface that doesn't throw exceptions.
(try-module-autoload): Simplify to take advantage of the fact that
primitive-load-path does the right thing with regards to loading
compiled files if they are available.
* libguile/read.c (flush_ws, scm_read_commented_expression)
(scm_read_sharp): Add support for commenting out expressions with #;.
(scm_read_syntax, scm_read_sharp): Add support for #', #`, #, and #,@.
* module/ice-9/boot-9.scm: Remove #' read-hash extension, which actually
didn't do anything at all. It's been there since 1997, but no Guile
code I've ever seen uses it, and it conflicts with #'x => (syntax x)
from modern Scheme.
* module/system/base/compile.scm (compile-and-load): Whoops, fix a number
of bugs here.
* module/ice-9/boot-9.scm (default-pre-unwind-handler): Since we were
tail-called by pre-unwind-handler-dispatch, we can't use
pre-unwind-handler-dispatch as a narrowing argument. Instead just
narrow by one frame.
(pre-unwind-handler-dispatch): Deprecate.
(error-catching-loop): Remove crack comment and code, and just use
default-pre-unwind-handler as our pre-unwind handler.
* module/ice-9/stack-catch.scm (stack-catch):
* module/system/repl/repl.scm (call-with-backtrace): Use
default-pre-unwind-handler directly.
* module/ice-9/boot-9.scm (cond): Implement srfi-61; most of the code is
from the SRFI itself. Yuk.
(%print-module, make-modules-in, %app, (%app modules))
(module-name): Syncase needs to get at the names of modules, even at
anonymous modules. So lazily assign gensyms as module names. Name %app
as (%app), but since (%app modules) is at the top of the module
hierarchy, name it ().
* module/ice-9/psyntax.scm: When building tree-il, try to name lambdas in
definitions and in lets.
(let, letrec): Give more specific errors in a couple of cases.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syntax.test: More work. Many exceptions have different
messages than they used to, many more generic; we can roll this back to
be faithful to the original strings, but it doesn't seem necessary to
me.
* module/ice-9/boot-9.scm (guile-user): Move the `compile' autoload to
the guile-user module. Remove reference to compile-time-environment.
* module/language/scheme/compile-ghil.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/optimize.scm:
* module/system/base/compile.scm:
* test-suite/tests/compiler.test: Remove definition of and references to
compile-time-environment. While I do think that recompilation based on
a lexical environment can be useful, I think it needs to be implemented
differently. So for now we've lost nothing if we take it away, as it
doesn't work with syncase anyway.
* libguile/vm-i-system.c:
* libguile/vm-engine.h (ASSERT_BOUND): New assertion, that a value is
bound. Used by local-ref and external-ref in paranoid mode.
* module/ice-9/boot-9.scm (and, or, cond, case, do): Since we are
switching to use psyntax as the first pass of the compiler, and perhaps
soon of the interpreter too, we need to make sure it expands out all
forms to primitive expressions. So define expanders for these derived
syntax forms, as in the R5RS report.
* module/ice-9/psyntax-pp.scm: Regenerate, with core forms fully
expanded.
* module/ice-9/psyntax.scm (build-void): New constructor, for making
undefined values.
(build-primref): Add in a hack so that primitive refs in the boot
module expand out to toplevel refs, not module refs.
(chi-void): Use build-void.
(if): Define an expander for if that calls build-conditional.
* module/language/scheme/compile-tree-il.scm (compile-tree-il): Use let*
so as not to depend on binding order for the result of
(current-module).
* module/language/scheme/spec.scm (scheme): Switch over to tree-il as the
primary intermediate language. Not yet fully tested, but at least it
can compile psyntax-pp.scm.
* module/language/tree-il/analyze.scm (analyze-lexicals): Arguments don't
count towards a function's nlocs.
* module/language/tree-il/compile-glil.scm (*comp-module*, compile-glil):
Define a "compilation module" fluid.
(flatten-lambda): Fix a call to make-glil-argument. Fix bug in
heapifying arguments.
(flatten): Fix number of arguments passed to apply instruction. Add a
special case for `(values ...)'. If inlining primitive-refs fails,
try expanding into toplevel-refs if the comp-module's variable is the
same as the root variable.
* module/language/tree-il/optimize.scm (resolve-primitives!): Add missing
src variable for <module-ref>.
* test-suite/tests/tree-il.test ("lambda"): Fix nlocs counts. Add a
closure test case.
* module/ice-9/boot-9.scm (delay): Define `delay' in terms of
make-promise.
* module/ice-9/psyntax-pp.scm (compile): Regenerated with a fully
compiled Guile, so that the gensym numbers are the same.
* module/language/tree-il/compile-glil.scm: Add some notes about what
needs doing to catch up to the old compiler.
* 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.
* 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.
* 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
* 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/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/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.
* 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/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/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/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.
