* module/system/base/compile.scm (next-pass): Invoke the language's
compiler chooser if there is more than one compiler.
(compute-compiler): Ensure from and to are languages.
* module/system/base/language.scm (<language>): Add compiler-chooser
field.
* module/language/brainfuck/spec.scm (choose-compiler, brainfuck):
Define a compiler chooser.
* 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").
Turns out this was not a very useful idea, and semantically tricky to
boot.
This reverts commit 24bf130fd1, and makes
the following additional changes:
* module/ice-9/optargs.scm (parse-lambda-case, let-optional)
(let-optional*, let-keywords, let-keywords*):
* module/language/tree-il.scm: (<lambda-case>, parse-tree-il)
(unparse-tree-il, tree-il->scheme, tree-il-fold,
make-tree-il-folder)
(post-order!, pre-order!):
* module/language/tree-il/analyze.scm (analyze-lexicals):
* module/language/tree-il/compile-glil.scm (compile-glil):
* module/language/tree-il/inline.scm (inline!): Remove all traces of
#:predicate from tree-il.
* module/ice-9/psyntax.scm (build-simple-lambda, build-lambda-case)
(chi-lambda-case): Adapt to tree-il change.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/brainfuck/compile-tree-il.scm (compile-body):
* module/language/ecmascript/compile-tree-il.scm (comp, comp-body):
* test-suite/tests/tree-il.test: Adapt to tree-il change.
* doc/ref/api-procedures.texi (Case-lambda): Remove mention of
#:predicate.
* module/language/tree-il.scm (<lambda-case>): Add "inits" field, so we
don't have to parse it out of opt and kw. Adapt the traversal
procedures.
* module/language/tree-il/analyze.scm (analyze-lexicals): Analyze
lexicals in the <lambda-case> init expressions as well. Fix keyword
allocation.
* module/language/tree-il/compile-glil.scm (compile-glil): Adapt to
make-lambda-case change.
(flatten): Adapt to "inits" slot, actually init uninitialized args,
and fix bugs related to keyword arguments.
* module/language/tree-il/inline.scm (inline!): Adapt a little bit --
but with no effect.
* module/language/glil/compile-assembly.scm (glil->assembly): Flesh out
<glil-kw-prelude> compilation some more. Add a "bound?" op for
<glil-lexical>, which will push #t if the local is bound.
* module/ice-9/psyntax.scm (build-simple-lambda, build-lambda-case):
Update for new signature of make-lambda-case.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/brainfuck/compile-tree-il.scm (compile-body):
* module/language/ecmascript/compile-tree-il.scm (comp):
* test-suite/tests/tree-il.test ("lambda"): Update for new lambda-case
syntax.
* test-suite/Makefile.am:
* test-suite/tests/brainfuck.test: Add a brainfuck test.
* module/system/base/compile.scm: Also export read-and-compile.
* module/language/tree-il/spec.scm (join): Fix the joiner in the
0-expression case.
* module/language/tree-il/primitives.scm (+): Recognize (+ x -1) as 1-.
* module/language/brainfuck/parse.scm (read-brainfuck): Return EOF if we
actually received EOF, and there were no expressions read.
* module/language/brainfuck/compile-tree-il.scm (compile-body): Fix the
compiler for the new format of "lambda" in tree-il.
* module/language/assembly/spec.scm:
* module/language/brainfuck/spec.scm:
* module/language/bytecode/spec.scm:
* module/language/ecmascript/spec.scm:
* module/language/glil/spec.scm:
* module/language/scheme/spec.scm:
* module/language/tree-il/spec.scm: Language-readers now take two
arguments: the port and the environment. This should allow for
compile-environment-specific reader behavior.
* module/system/base/compile.scm (read-and-compile):
* module/system/repl/common.scm (repl-read): Pass the environment to the
language-reader.
* module/system/repl/repl.scm (meta-reader, prompting-meta-read):
* module/system/repl/command.scm (define-meta-command): Use the second
argument to repl-reader, so we avoid frobbing current-reader.
* module/language/brainfuck/compile-tree-il.scm (compile-tree-il):
Remove the hack where we wrapped the compiled code in a `lambda',
because not only should the tree-il compiler optimize that away, it
was really papering around other inefficiencies, and obtuse to boot.
* module/language/brainfuck/compile-tree-il.scm (compile-tree-il): Wrap
the result in a ((lambda () ...)), so we can use toplevel-ref. Add
lots more comments.
* 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/compiler.texi: Mention the new brainfuck compiler as an example.
* module/language/brainfuck/compile-scheme.scm: Add a lot of documentation comments.
* module/language/brainfuck/parse.scm: Ditto.
* module/language/brainfuck/spec.scm: Ditto.
* module/Makefile.am: Install the brainfuck compiler modules.
* module/language/brainfuck/spec.scm: New file.
* module/language/brainfuck/parse.scm: New file.
* module/language/brainfuck/compile-scheme.scm: New file.
