* 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.
* module/language/ecmascript/compile-ghil.scm: Use -> to make the ES
compiler more readable. Fix bugs in do, while, and for, whereby we were
missing ->boolean calls.
* module/language/ecmascript/base.scm (prop-keys): New method, returns
the list of keys of props of this instance.
* module/language/ecmascript/impl.scm: Refactor the global object into a
special kind of module object. Provide a prop-keys implementation for
module objects.
* module/language/ecmascript/compile-ghil.scm (comp): Compile for-in.
* module/language/ecmascript/impl.scm: Reshuffly things, and implement
make-enumerator, a helper for use in for-in statements.
* module/language/ecmascript/parse.scm (parse-ecmascript): Fix parsing of
for (var foo in bar) {}...
* module/language/ecmascript/impl.scm: Add <js-module-object>, that wraps
a module. Add js-require, a javascript-happy function that returns an
object that wraps a Guile module. Bind it to `require' in the default
environment.
* module/language/ecmascript/tokenize.scm: Attach source information to
tokens. We have to enhance the lalr parser to actually let this
information propagate through, though...
* module/language/ecmascript/array.scm (*array-prototype*): Declare the
constructor.
* module/language/ecmascript/base.scm (pput, pdel): Remove some needless
checks.
(new): Move definition of new here, and use the constructor.
* module/language/ecmascript/compile-ghil.scm (compile-ghil): Add a stub
so that when we load a compiled JS program, we make sure the runtime
has been booted.
* module/language/ecmascript/function.scm (js-constructor): Export a
js-constructor method instead of a new method.
* module/language/ecmascript/impl.scm (<js-global-object>): Define a new
class for the global "this" object, wrapping bindings from the current
module.
(init-js-bindings!): Define the dozen or so global properties, in the
current module.
(+): Define addition operations for non-numbers. This is efficient
because the generics are only dispatched if the fast-path fails.
* module/language/ghil/compile-glil.scm (codegen): If there are more than
255 arguments, make a list and use apply instead of calling directly.
* module/language/Makefile.am: Now we can compile parse.scm. Yay!
* module/language/scheme/compile-ghil.scm: Add a note.
* module/language/ecmascript/compile-ghil.scm: Add a note.
* module/language/Makefile.am: OK, we can compile compile-ghil.scm now,
thankfully.
* module/language/ecmascript/compile-ghil.scm (ormatch): New macro, a
wrapper around pmatch to avoid some of the more egregious
non-tail recursiveness.
(comp): Use ormatch.
* module/language/ghil.scm (unparse-ghil): The body of bind and mv-bind
is a single expression, not a list of expressions.
* module/language/ghil/compile-glil.scm (codegen): Be more clever when
allocating "local" variables -- if a variable goes out of scope, its
index can be re-used later.
* module/language/glil.scm (parse-glil, unparse-ghil): The "rest" of a
mv-bind is a flag, not a list. The "ra" of an mv-call is a label, not a
GLIL expression.
* module/language/objcode/spec.scm (collapse-locals, decompile-value):
When decompiling a value, process the bindings list differently.
Comments in the code.
* module/language/scheme/compile-ghil.scm (define-scheme-translator): Fix
the generated error procedure.
(let): Re-indent.
(letrec): Re-indent.
* module/system/base/syntax.scm (record-case): If the body of a clause is
null, fill it with the unspecified value.
* libguile/vm-i-system.c (goto/args): On a tail call to a different
procedure, init the locals to valid scheme values. Shouldn't matter for
well-compiled scheme, but inspecting uninitialized locals could give
garbage, or badly-compiled code could cause a crash.
* module/language/Makefile.am (NOCOMP_SOURCES): For the moment, don't
compile compile-ghil.scm. I need to fix this.
* module/language/ecmascript/compile-ghil.scm (load-toplevel): Sigh, and
disable stack checking in the evaluator too. Grr.
(comp): Implement (unnamed) break and continue.
* module/language/ecmascript/parse.scm (parse-ecmascript): Fix var
statements in `for' -- though it still doesn't work.
* module/language/ecmascript/compile-ghil.scm (comp): Use ghil-bind when
making temp vars, so that disassembly understands things. Implement do,
while, and for.
* module/language/ecmascript/parse.scm (parse-ecmascript): Some tweaks.
* module/language/ecmascript/impl.scm (language): Export ->boolean.
* module/language/ecmascript/base.scm: Implement some more robust
property getters that convert strings to symbols. Implement
has-property?.
* module/language/ecmascript/compile-ghil.scm (comp): Implement lots more
mathematical operators. We now do all expressions; on to statements.
* module/language/ecmascript/impl.scm: Define some math helpers. They
probably need to call ->number on some things.
* module/language/ecmascript/parse.scm (parse-ecmascript): Fix a typo.
* module/language/ecmascript/compile-ghil.scm (@impl): Implement with
@implv.
(comp): Implement ++ and -- (pre- and post-). Quite a pain. I'll be
looking for ways to simplify this notation. Also implement new, delete,
and void.
* module/language/ecmascript/impl.scm: Implement typeof.
* module/language/ecmascript/base.scm:
* module/language/ecmascript/compile-ghil.scm:
* module/language/ecmascript/impl.scm:
* module/language/ecmascript/parse.scm: Compile "method calls" in such a
way that "this" gets propagated correctly.
* module/language/Makefile.am:
* module/language/ecmascript/impl.scm:
* module/language/ecmascript/array.scm:
* module/language/ecmascript/base.scm:
* module/language/ecmascript/function.scm: Split out the runtime into
different files. Implement more of the spec's runtime.
* module/language/ecmascript/parse.scm (parse-ecmascript): And update the
function declaration forms for the new var syntax.
* module/language/ecmascript/compile-ghil.scm (comp): Support foo["bar"]
in addition to foo.bar.
* module/language/ecmascript/impl.scm (pget, pput): Some fixes for when
we get non-symbols -- it can happen, yo. I suppose we should allow for
non-string keys too..
* module/language/ecmascript/compile-ghil.scm (@impl): Ok, don't recurse
on args here.
(comp): Implement property gets and puts and lexical assignment.
(comp-body): Fix scanning of var forms.
* module/language/ecmascript/impl.scm (prop-attrs): Allow for the prop
attr array to be #f.
* module/language/ecmascript/parse.scm (parse-ecmascript): Fix assignment
parsing.
* libguile/vm-i-system.c (drop, return): Declare drop and return as
popping one arg from the stack.
* module/language/ghil/compile-glil.scm:
* module/language/glil/compile-assembly.scm (make-meta): Adjust so that
we declare 'drop and 'return calls as popping one arg from the stack.
* module/language/ecmascript/compile-ghil.scm (comp, comp-body): Flesh
out a bit more. Most significantly, scoping within functions obeys
javascript semantics better, modulo bits about with() forms.
* module/language/ecmascript/impl.scm: Define some runtime helper
routines.
* module/language/Makefile.am (SOURCES): Add impl.scm.
* module/language/ecmascript/parse.scm (parse-ecmascript): Minor tweaks.
* module/language/ecmascript/tokenize.scm (read-identifier): Identifiers
now read as symbols, not strings.
* module/language/ecmascript/parse.scm (parse-ecmascript): Lambdas always
just have one member in their bodies.
* module/language/ecmascript/compile-ghil.scm (comp): Add some more silly
compilers.
* module/language/ecmascript/parse-lalr.scm: Add the Boucher/Bison lalr
parser. This is from guile-lib, but with : changed to -> so as not to
molest `prefix' keywords. Should probably be elsewhere.
* module/language/ecmascript/parse.scm: Add parser for ECMAScript. Rules
from the spec, 3rd edition.
* module/language/ecmascript/tokenize.scm: Add ECMAScript tokenizer,
hand-written. Neat stuff.
* module/language/Makefile.am: Autofoo.
