* 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/ice-9/boot-9.scm (repl-reader): Accept an optional second
argument, the reader to use. If it is given, use it instead of
dereferencing the current-reader fluid.
* guile-readline/ice-9/readline.scm (activate-readline): Make our
replacement definition of repl-reader compatible with boot-9.
* libguile/arrays.c (scm_from_contiguous_typed_array):
* libguile/bytevectors.c (scm_uniform_array_to_bytevector): Error if the
uniform element size is more than 8 bits, but not divisible by 8 --
because our math could overflow in that case.
* module/ice-9/deprecated.scm (#\y): Indeed, #* is the valid bitvector
syntax :)
* libguile/arrays.c (scm_from_contiguous_typed_array): Fix BYTE_LEN
sanity check for bitvectors.
* test-suite/tests/unif.test ("syntax")["bitvector is self-evaluating"]:
New test.
* module/ice-9/deprecated.scm (#\y): Fix deprecation comment: `#*' is
not a read syntax.
* module/ice-9/boot-9.scm (load): Pull `autocompiled-file-name' inside
`load', and make it autocompile in the current module. Should fix
Julian's issue noted in
http://article.gmane.org/gmane.lisp.guile.devel/9483.
* module/ice-9/boot-9.scm (set-module-eval-closure!): Add link to an
explanation.
* test-suite/tests/gc.test ("gc")["Unused modules are removed"]:
Increase the `cleanup' loop.
i.e. put the extensions where they need to be, and delete
ice-9-debugger-extensions.scm.
* doc/ref/api-debug.texi (Single Stepping through a Procedure's Code):
Change mentions of (ice-9 debugging ice-9-debugger-extensions)
module to whatever is appropriate now (or just remove them).
* module/Makefile.am (NOCOMP_SOURCES): Remove
ice-9-debugger-extensions.scm.
* module/ice-9/debugger.scm (debug-trap): Move here from
ice-9-debugger-extensions.scm.
* module/ice-9/debugger/command-loop.scm ("continue", "finish",
"step", "next"): Move here from ice-9-debugger-extensions.scm.
* module/ice-9/debugger/commands.scm (assert-continuable, continue,
finish, step, next): Move here from ice-9-debugger-extensions.scm.
* module/ice-9/debugging/breakpoints.scm: Don't use
ice-9-debugger-extensions module.
* module/ice-9/debugging/ice-9-debugger-extensions.scm: Removed.
* module/ice-9/debugging/trace.scm, module/ice-9/debugging/traps.scm:
Remove more old version code.
* module/ice-9/debugging/traps.scm (guile-trap-features): Hardcoded as
'(tweaking).
* module/ice-9/debugging/ice-9-debugger-extensions.scm: Remove all
code checking for version < 1.7, and move code for versions >= 1.7
up to top level. Comment out dummy mutex definitions for now, as
I'm not sure how to rewrite them correctly for psyntax.
* module/ice-9/boot-9.scm (eval): Here at the tail of boot-9, replace
the root definition of `eval' with a procedure that will call
`compile'.
* test-suite/tests/syntax.test ("top-level define"):
("internal define"): Run unmemoization tests in the interpreter, using
primitive-eval.
* module/ice-9/boot-9.scm (@bind): Define a VM-compatible syntax
definition for this old evaluator primitive.
* test-suite/tests/dynamic-scope.test: Change the expected error
messages.
* libguile/load.h:
* libguile/load.c (scm_sys_warn_autocompilation_enabled): New primitive,
not exported. Since `load' autocompiles now, it should warn in the
same way that the bits hardcoded into C warn.
(scm_try_autocompile): Use scm_sys_warn_autocompilation_enabled.
* module/ice-9/boot-9.scm (autocompiled-file-name): New helper.
(load): Try autocompiling the argument, if appropriate. Will
autocompile files passed on Guile's command line. `primitive-load' is
unaffected.
* module/ice-9/boot-9.scm (module-name): When making MOD non-anonymous,
bind it in the `(%app modules)' name space.
* test-suite/tests/compiler.test ("psyntax")["compile in current
module", "compile in fresh module"]: New tests.
* test-suite/tests/modules.test ("foundations")["modules don't remain
anonymous"]: New test.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (chi-top)[define-form]: If a same-named
imported variable exists, take its value instead of `#f'.
* test-suite/tests/compiler.test ("psyntax")["redefinition"]: New tests.
* module/ice-9/psyntax.scm (build-lexical-var): Make our gensyms really
unique. Before, there was a chance that different lexicals could
result in the same gensym.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (source-wrap): Use decorate-source, for
clarity.
(syntax-type): When turning the RHS of (define (foo) ...) into a
lambda, decorate the resulting lambda expression with source
information, as the RHS later goes to chi-expr, which receives no
source information. Perhaps that is a bug. In any case, fixes some
source location lossage, reported by Jao.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/boot-9.scm (define-private): Remove apocyphal comment. The
FIXME would really be to remove `define-private', though...
* module/ice-9/optargs.scm (defmacro*, defmacro*-public): Fix these
macros. Thanks to Dale Smith for the report.
* module/ice-9/boot-9.scm (define-option-interface): Fix (debug-options
'full), along with other options. Thanks to Mark Weaver for the tip.
* THANKS: Update, though many more names need to be added.
* module/language/ecmascript/compile-ghil.scm (comp): Just use pmatch,
not ormatch. Now with syncase running over everything, it doesn't
matter.
* module/ice-9/boot-9.scm (false-if-exception): Avoid saving stacks
inside false-if-exception. There's probably a more general solution to
this, though. Fixes getting bogus backtraces sometimes.
* module/Makefile.am (ECMASCRIPT_LANG_SOURCES): Reorder things so that
spec comes last.
* module/ice-9/compile-psyntax.scm: Pretty-print psyntax-pp.scm, given
that we are going to compile it anyway.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/Makefile.am (ice-9/psyntax-pp.scm): Don't try autocompiling when
making psyntax-pp.scm.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-top): Only affect the compile-time
environment if modules have booted.
* libguile/vm-i-scheme.c (FUNC2): Use a signed value for the intermediate
result here. Not sure what the effect is, though.
* module/ice-9/psyntax.scm (chi-top): Toplevel definitions ensure that
variables are defined in the current module. Fixes the specific case of
guile-lib's md5.scm, which redefines + -- this code is needed so that
we don't incorrectly open-code +.
* module/language/tree-il/primitives.scm (resolve-primitives!): I think
there were some cases in which vars and names would not resolve
properly here. Fix those.
* module/ice-9/psyntax.scm (syntax-type): Remove `external-macro', not
used any more. Take an extra arg, `for-car?', indicating that we're
checking on the type of a form in the car position. In the case that
the expression is a pair, do a full recursion on the car, which allows
us to catch the fact that the car of the following form is a macro:
((@ (ice-9 optargs) let-optional) ...)
and thus the form itself should be macroexpanded.
But, since we want to distingush `lambda' from `(lambda ...)', just as
we have global and global-call, we have core to the new `core-form'.
(chi-top, chi, chi-expr, chi-body, set!): Adapt to changes to
syntax-type.
* libguile/init.c (scm_load_startup_files): Use
scm_c_primitive_load_path.
* libguile/load.c (scm_primitive_load_path): Add an optional arg,
exception_on_error, which if #f will cause primitive-load-path to just
return #f if no file is found. This is to help out the semantics of
try-module-autoload. We can't just catch misc-error, because loading
the file could raise any exception.
(scm_c_primitive_load_path): Add the extra arg to
scm_primitive_load_path.
* libguile/load.h: Adapt scm_primitive_load_path prototype.
* module/ice-9/boot-9.scm (try-module-autoload): Refactor slightly to be
clearer.
* 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.
* 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/ice-9/psyntax.scm (source-annotation): Return #f if
source-properties returns null.
(source-wrap): Rework a bit.
(syntax-type): Don't throw away source info for wrapped expressions.
Can has source location info, fools!
(chi-body): Correctly propagate source info for body subforms.
(syntax): Remove special case for map, it doesn't apply (ahem) for
Guile.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm: Remove references to annotation objects,
we're just going to try and use Guile's source properties now. It works
until `syntax' reconstructs output, at which point it seems we lose it.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-body): Fix a problem introduced in
dc1eed52f7, that internal syntax definitions were included in the id
lis along with value definitions. Only showed up on a second bootstrap.
Psyntax, how I love thee.
* module/ice-9/psyntax-pp.scm
* module/ice-9/threads.scm: Move syntax definitions before the procedures
that use them, and rewrite as hygienic macros since they are so much
nicer that way. Fixes the thread tests.
* 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/language/tree-il.scm (tree-il->scheme):
* module/ice-9/psyntax.scm (build-conditional): Attempt to not generate
(if #f #f) as the second arm of an if, but it doesn't seem to be
successful.
* module/ice-9/psyntax-pp.scm (syntax-rules): Regenerate.
* test-suite/tests/syntax.test (exception:unexpected-syntax): Change
capitalization.
("unquote-splicing"): Update test.
("begin"): Add in second arms on these ifs, to avoid the strange though
harmless expansion of `if'.
(matches?): New helper macro.
("lambda"): Match on lexically bound symbols, as they will be
alpha-renamed.
