* module/system/base/language.scm (current-language): Default to 'scheme
here, rather than relying on *current-language* always being bound.
Thanks to 亚光唐 <texnician@gmail.com> for the report.
* module/system/base/compile.scm:
* module/system/base/language.scm (*current-language*, current-language):
Move this fluid and thunk down to (system base language).
* module/system/base/language.scm (<language>): Remove the `version'
field from languages. It just wasn't useful.
* module/language/assembly/spec.scm:
* module/language/brainfuck/spec.scm:
* module/language/bytecode/spec.scm:
* module/language/ecmascript/spec.scm:
* module/language/elisp/spec.scm:
* module/language/glil/spec.scm:
* module/language/objcode/spec.scm:
* module/language/scheme/spec.scm:
* module/language/tree-il/spec.scm:
* module/language/value/spec.scm: Remove #:version from all language
definitions. Shorten some language names (e.g. "Guile Scheme" ->
"Scheme").
* module/ice-9/boot-9.scm (make-fresh-user-module): New public function,
makes an anonymous beautified module.
* module/language/objcode/spec.scm: We used to have some things in here
that allowed lexical variable names and values to be a part of the
environment, but no more. Now an environment is just a module. If you
want to "inject" free variables into code, just use lambda.
* module/language/scheme/compile-tree-il.scm (compile-tree-il): Same
here. Also, rely on the fact that an environment *will* be a module --
because (system base compile) guarantees that for us.
* module/language/scheme/spec.scm (scheme): In the reader, rely on the
environment being a module. Define a #:make-default-environment
handler, which returns a beautified module, augmented with a fresh
definition for current-reader, so that side effects to current-reader
are restricted to the compilation unit.
* module/language/tree-il/analyze.scm
(report-possibly-unbound-variables):
* module/language/tree-il/compile-glil.scm (compile-glil):
* module/language/tree-il/optimize.scm (optimize!): The environment will
be a module.
* module/system/base/language.scm (<language>): New field,
`make-default-environment'. Defaults to `make-fresh-user-module'.
(default-environment): New accessor, returns a default environment for
a language.
* module/system/repl/common.scm (repl-compile): Always compile relative
to the current module, because a module is always acceptable as an
environment.
* module/system/base/compile.scm (compile-file, compile-and-load): Both
of these have a new keyword argument, #:env. For `compile-file', it
defaults to the default environment of the source language, and for
`compile-and-load', to the current module.
(read-and-compile): If there are no expressions read, pass the joiner
its default environment (via `default-environment joint').
* module/Makefile.am (BRAINFUCK_LANG_SOURCES): Compile at the end. Add
compile-tree-il.scm.
* module/language/brainfuck/compile-tree-il.scm: New compiler, compiles
to tree-il instead of scheme. I thought it would be more illustrative,
though there are some uncommented bits.
* module/language/brainfuck/parse.scm: Modify not to put a header on the
scheme representation. After all, we don't put <scheme> before scheme
code, do we? :)
* module/language/brainfuck/spec.scm: Add tree-il compiler.
* module/language/tree-il.scm: Understand (set! (lexical foo) ...).
* module/system/base/language.scm: Update license. Actually, updates
licenses on all these.
* doc/ref/api-procedures.texi (Compiled Procedures): Fix for API changes.
* doc/ref/compiler.texi (Compiling to the Virtual Machine): Replace GHIL
docs with Tree-IL docs. Update the bits about the Scheme compiler to
talk about Tree-IL and the expander instead of GHIL. Remove
<glil-argument>. Add placeholder sections for assembly and bytecode.
* doc/ref/vm.texi: Update examples with what currently happens. Reword
some things. Fix a couple errors.
* libguile/vm-i-system.c (externals): Remove this instruction, it's not
used.
* module/ice-9/documentation.scm (object-documentation): If the object is
a macro, try to return documentation on the macro transformer.
* module/language/assembly/disassemble.scm (disassemble-load-program):
Fix problem in which we skipped the first element of the object vector,
because of changes to procedure layouts a few months ago.
* module/language/scheme/spec.scm (read-file): Remove read-file
definition.
* module/language/tree-il.scm: Reorder exports. Remove <lexical>, it was
a compat shim to something that was never released. Fix `location'.
* module/language/tree-il/primitives.scm (/): Fix expander for more than
two args to /.
* module/system/base/compile.scm (read-file-in): Remove unused
definition.
* module/system/base/language.scm (system): Remove language-read-file.
* module/language/ecmascript/spec.scm (ecmascript): Remove read-file
definition.
* 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/syntax.scm (define-record): So, in the generated
constructors, allow optional arguments, but not keyword arguments.
Conses much less in the constructors.
(define-record/keywords): And the old define-record is here.
* module/language/ghil.scm (parse-ghil):
* module/language/ghil/compile-glil.scm (codegen):
* module/language/scheme/compile-ghil.scm (translate-1, quote)
(quasiquote): Don't use keywords in this compiler hotpath.
* module/system/base/language.scm (<language>):
* module/system/repl/common.scm (<repl>):
* module/system/vm/debug.scm (<debugger>): Use define-record/keywords.
* module/language/assembly/Makefile.am:
* module/language/assembly/spec.scm:
* module/language/assembly/decompile-bytecode.scm: Add a bytecode
decompiler. Neat!
* module/language/bytecode/spec.scm (decompile-objcode):
* module/language/objcode/spec.scm (decompile-value): Add some
"decompilers" here too.
* module/system/base/compile.scm (current-language): Since we can refer
to languages by name, do so here -- removes the previous
anti-circularity hack.
(compile-file, compile): Refer to target languages by name.
(decompile): New public function. Neat!
* module/system/base/language.scm (lookup-decompilation-order): Fix so we
look for decompilers with the high-level language definition.
* module/system/base/language.scm (lookup-decompilation-order): New
function, like its compiling cousin, but backwards.
(compute-translation-order): Rework so that languages can be specified
either by name or by identity. Return a list of language - procedure
pairs, without the "to" language in the list, instead of a list of
languages.
(invalidate-compilation-cache!): Invalidate the decompilation cache
too.
(<language>): Add a decompiler field.
* module/system/base/compile.scm (compile-passes): Much simpler now that
lookup-compilation-order gives us the procedures directly.
* module/language/*/spec.scm: Specify compilers by name, so that we can
avoid unnecessary module loads, and so that when we specify
decompilers, we can avoid cycles.
* 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!
* module/system/repl/common.scm (repl-print): Slightly refine the meaning
of "language-printer": a language printer prints an expression of a
language, not the result of evaluation. `write' prints values.
* module/language/ghil/spec.scm (ghil): Define a language printer, and a
translator for turning s-expressions (not scheme, mind you) into GHIL.
* module/language/scheme/translate.scm (quote, quasiquote): Add some
#:keyword action, so that we can (quote #:keywords).
* module/system/base/language.scm (<language>):
* module/system/base/compile.scm (read-file-in): Don't require that a
language have a read-file; instead error when read-file is called.
(compile-passes, compile-in): Refactor to call a helper method to turn
the language + set of options into a set of compiler passes.
* module/system/base/syntax.scm (define-type): Allow the type to be a
list, with the car being the name and the cdr being keyword options.
Interpret #:printer as a printer, and pass it down to...
(define-record): Here.
* module/system/il/ghil.scm (print-ghil, <ghil>): New printer for GHIL,
yay!
(parse-ghil, unparse-ghil): New lovely functions. Will document them in
the manual.
* module/system/base/syntax.scm (keywords): Don't enable :keywords, it
breaks code that may assume that ':foo is a symbol, like boot-9.
* module/*.scm: Don't use :keywords, use #:keywords. The user can decide
if she wants #:keywords in their .guile, and :keywords might make us
compile modules differently.
* module/language/scheme/translate.scm (*the-compile-toplevel-symbol*):
Reset to compile-toplevel, which requires a patch to guile.
* module/system/base/compile.scm (compile-file): Some foo so that we load
up the scheme language before call-with-output-file. Fixes compilation
of (language scheme) modules.
* module/system/base/language.scm (define-language): Don't unquote in
make-language; refer to it by name instead, and export it.
* module/system/repl/Makefile.am (vm_DATA): Don't compile describe.scm,
because we really can't deal with goops yet.
* module/system/repl/repl.scm (compile-toplevel): If we're compiling, put
in a stub definition of start-stack, which is closely tied to the
interpreter.
* src/vm_loader.c (load-program): Fix a very tricky corruption bug!
* module/system/base/syntax.scm (define-record): Rework to separate the
type and its constructor. Now (define-record (<foo> bar)) will create
`make-foo' as the constructor, not `<foo>'. Also the constructor now
takes either keyword or positional arguments, so that it can be used as
the implementation of variant types as well.
(|): Map directly to define-record instead of rolling our own thing.
* module/language/scheme/translate.scm:
* module/system/base/language.scm:
* module/system/il/compile.scm:
* module/system/il/ghil.scm:
* module/system/il/glil.scm:
* module/system/repl/common.scm:
* module/system/vm/assemble.scm:
* module/system/vm/debug.scm: Change instances of record creation to use
the make-foo procedures instead of <foo>. Adjust module exports as
necessary.
* module/language/Makefile.am: New.
* module/language/scheme/Makefile.am: New.
* configure.in: Produce these two new Makefiles.
* doc/guile-vm.texi: Documented `compile-file', `compiled-file-name', and
`compile-in'.
* module/system/base/compile.scm: Cosmetic changes.
* module/system/base/language.scm: Likewise.
* module/system/il/Makefile.am: Tried (and failed) to compile more
things.
* module/system/vm/Makefile.am: All source files in here can now be
compiled without harming further compilation.
* module/system/vm/assemble.scm: Select only specific bindings from
`(system vm core)'.
(dump-object!): Show a more meaningful error message.
* module/system/vm/conv.scm: Select only specific bindings from `(system
vm core)'.
* module/system/vm/debug.scm: Likewise.
* module/system/vm/frame.scm: Changed the header. Use a renamer for
`(system vm core)'.
* src/guilec.in: Added options, via `getopt-long'.
