dec62b5ef8 make syncase aware of (set! (@ (foo) bar) baz)
* module/ice-9/psyntax.scm (set!): Handle (set! (@ (foo ..) bar) val)
  inside syncase. Heh heh heh.

* module/ice-9/psyntax-pp.scm: Regenerated.

265e61273d syncase knows about @ / @@
* module/ice-9/psyntax.scm (syntax-type): Handle a new type, module-ref.
  Like external-macro, it also has a procedure as a binding.
  (chi-expr): module-ref forms -- that is to say, (@ (foo ...) bar) -- as
  expressions they are global references, but with respect to a specific
  module.
  (@, @@): Define module-ref syntax handlers.

* module/ice-9/psyntax-pp.scm: Regenerated.

* module/ice-9/syncase.scm: Mark as primitive syntax so we don't clobber
  their definitions.

The reason I'm doing things like this is so as to support (set! (@@ ...)
...) sensibly, which will be the next patch.

d4876cb413 distcheck fixen
* examples/Makefile.am: Fix the installed guile-config invocation to set
  PKG_CONFIG_PATH.

* meta/Makefile.am (EXTRA_DIST): Dist the bin_SCRIPTS.

* meta/guile-config (pkg-config): Better error messages if pkg-config
  invocation fails.

* meta/uninstalled-env.in (PATH): Now that guile-config and guile-tools
  are not generated, make it the srcdir/meta instead of the builddir.
  (Guile itself will be picked up from libguile.)

fb3807793f scripts take rest args
* meta/guile-tools: Instead of fixing scripts I should have been fixing
  the script runner.

* module/scripts/compile.scm:
* module/scripts/snarf-guile-m4-docs.scm: Fix to take rest args.

807da8804c some more build fixes for bugs that I introduced
* meta/guile-1.8.pc.in: Include a pkgdatadir, which will map down to
  `guile-config info pkgdatadir', used in existing guile.m4 files.

* meta/guile-config: Fix guile-config info varname. Facepalm.

* meta/guile.m4: Make GUILE_SITE_DIR use the sitedir variable instead.
  Really it should use pkg-config directly, though.

2b4b555b8f fix build errors on fresh checkout
* meta/guile-tools: We can't use srfi-1, because on a fresh checkout
  the srfi-1 shlib isn't built yet. Bummer.

* meta/uninstalled-env.in: Fix up the DYLD lines for BSDen.

* module/scripts/snart-guile-m4-docs.scm: Fix expected arguments.

69dd78d7c8 no positions when reading psyntax-pp, validation in @/@@, cleanups
* module/ice-9/syncase.scm (old-debug): Re-disable position recording
  when reading psyntax-pp.

* libguile/eval.c (scm_m_at, scm_m_atat): More input validation.

* libguile/debug.c (scm_procedure_module): Use scm_env_module. Remove
  extraneous docstring.

c5cc65ac0c fix hygiene + modules + local macros
* module/ice-9/psyntax-pp.scm: Regenerate.

* module/ice-9/psyntax.scm (syntax-type): Look up the type of the car of
  a form relative to its module, if it is a syntax object. Fixes hygiene
  wrt modules and private macros.

* module/ice-9/syncase.scm (sc-macro): Add a comment.

* module/system/base/pmatch.scm: The big test case: just export pmatch,
  not ppat too.

196b40932e fix handling of pre-modules errors in the vm
* libguile/vm-i-system.c (toplevel-ref, toplevel-set): Correct situation
  whereby we would not throw when toplevel vars were unbound, before
  modules had booted.
2009-04-17 15:20:18 +02:00

249bab1c53 @ and @@ as primitive macros
* 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.

900761bc8d hygienic compilation
* module/language/scheme/compile-ghil.scm (lookup-transformer): Recognize

  compilation.

d2b61fe0ff houston, we have hygiene
* module/ice-9/expand-support.scm (strip-expansion-structures): Enable
  @/@@ substitution.

* module/ice-9/psyntax-pp.scm: Recompile.

* module/ice-9/psyntax.scm: Since syntax objects are quotable, make the
  module field the module name, not the module itself. Scope the operand
  of global calls appropriately. Thread modules through syntax-dispatch
  destructuring. Houston, we have hygiene.

* module/ice-9/syncase.scm: Adapt to module / module-name changes.

8e1d0d507a more work on modules and hygiene, not finished yet, alas.
* module/ice-9/compile-psyntax.scm: No more expansion-eval-closure.

* module/ice-9/expand-support.scm (strip-expansion-structures): Only @@
  names whose module is not the current module. Actually @@ serialization
  is disabled for this commit, just to get this one in and keep things
  working.

* module/ice-9/psyntax-pp.scm: Recompiled.

* module/ice-9/psyntax.scm (put-global-definition-hook)
  (get-global-definition-hook): Instead of going through that stupid
  getprop/putprop interface, let's just inline Guile-specific code here.
  (build-global-reference, build-global-assignment): Fix a bug where the
  module and public? were switched, which happily allowed things to
  compile. (We reintroduce a similar bug above in expand-support.)
  (lookup): Add a module argument.
  (global-extend): Adapt for put-global-definition-hook invocation.
  (syntax-type): Lookup with mod. Return mod even for lexicals and
  define-form -- why not.
  (chi-top, fluid-let-syntax, syntax, set!): Lookup with mod. Wrap with
  mod.

* module/ice-9/syncase.scm (expansion-eval-closure)
  (current-eval-closure, env->eval-closure): OK! So the idea is: module
  hygiene is syncase's business, not ours. So lose the eval-closure
  fluid. Also, eval closures are so 1990s.
  (sc-macro): But, we have to take the module from the env, sadly. In the
  future this will be different.
  Remove the rest of the eval-closure bits. Enable source reporting,
  while we're debugging.

* module/language/scheme/compile-ghil.scm (lookup-transformer): Adapt for
  eval closure fluid changes.

daedb4920a eval-closure-module, here hopefully not for long
* libguile/modules.h:

  new-yet-deprecated accessor, to ease a transition.

4e237f1460 thread the module through syntax-case's expansion
* libguile/debug.h:
* libguile/debug.c (scm_procedure_module): New procedure, returns the
  module that was current when the given procedure was defined. Used by
  syncase to scope free identifiers.

* module/ice-9/psyntax-pp.scm: Recompiled.

* module/ice-9/psyntax.scm: Thread the module through the syntax
  expansion. This is harder than it would appear because in many places
  the different components of syntax objects are destructured.

* module/ice-9/syncase.scm (guile-macro): Adapt to new signature for
  syntax transformer functions.
2009-04-17 15:20:16 +02:00

e02e84deed finish bootstrap to syntax-objects with modules
* module/ice-9/psyntax.scm: Now that we have gone through the
  intermediate step (in which both representations of syntax-object had
  to coexist), change all callers to make-syntax-object to pass the third
  argument, and restore the define-structure definition of syntax
  objects.

* module/ice-9/psyntax-pp.scm: Recompile.
2009-04-17 15:20:16 +02:00
Andy Wingo
1641568c33 add modules to syntax objects (part 1, intermediate step)
* module/ice-9/psyntax.scm (make-syntax-object): As an intermediate step
  to adding modules to syntax objects, replace the definition of
  syntax-object as a structure with an expanded-out definition that has
  (1) a constructor that takes 2 or 3 arguments, and (2) a predicate that
  works with vectors of length 3 or 4. I couldn't just redefine
  make-syntax-object, for example, because these are internal
  definitions, and we can't have duplicate bindings in a letrec.

9d80c15649 serialize module information into syncase's output -- getting ready for hygiene
* module/ice-9/Makefile.am: Replace annotate.scm with expand-support.scm.

* module/ice-9/annotate.scm: Removed; subsumed into expand-support.scm.

* module/ice-9/compile-psyntax.scm: Strip out expansion structures before
  writing to disk.

* module/ice-9/expand-support.scm: New file. Provides annotation support,
  and other compound data types for use by the expander. Currently the
  only one that is used is the toplevel reference, <module-ref>, but we
  will record lexicals this way soon.

* module/ice-9/psyntax-pp.scm: Regenerate.

* module/ice-9/psyntax.scm (build-global-reference)
  (build-global-assignment): Instead of expanding out global references
  as symbols, expand them as <module-ref> structures, with space to
  record the module that they should be scoped against. This is in
  anticipation of us actually threading the module info through the
  syntax transformation, so that we can get hygiene with respect to
  modules.

* module/ice-9/syncase.scm: Replace eval-when. Since sc-expand will give
  us something that isn't Scheme because we put the <module-ref>
  structures in it, strip that info whenever we actually do need scheme.

* module/language/scheme/compile-ghil.scm (lookup-transformer): Strip
  expansion structures here too.

* module/language/scheme/expand.scm (language): Swap annotate for
  expand-support. But this file will die soon, I think.

17df23e324 fix a tricky GC bug in scm_c_make_subr
* libguile/procs.c (scm_c_make_subr): Fix a really tricky bug!!! If
  scm_double_cell caused GC, the symbolic name wouldn't be marked. But
  the symptom wouldn't appear until you accessed that symbol much later,
  for example during tab completion / apropos grovelling. Not sure why we
  didn't see this earlier.

6d66647d5b guile-tools is a scheme script that loads scheme modules
* meta/guile-tools: Changed to be a scheme script. Instead of looking for
  executables in a "scripts dir", we just look for modules in (scripts),
  and load the modules directly.

* module/Makefile.am:
* module/scripts/: Move the scripts into module/ so they can be compiled.
  Rename scripts from `foo' to `foo.scm'.

* libguile/Makefile.am: Invoke the snarf->texi code via guile-tools.

* configure.in:
* .gitignore: Update for changes.

798244609b fix a couple gc-related continuations bugs
Thanks to Juhani Rantanen for the report.

* libguile/continuations.c (scm_make_continuation): Delay making the smob
  until the data is fully initialized. Fixes a bug whereby a GC in
  scm_vm_capture_continuations would catch the us with an undefined
  continuation->vm_conts, leading to marking badness.

* libguile/vm.c (vm_cont_free): Report the correct size to scm_gc_free.

b8076ec6cc support expression-by-expression compilation
* 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.

b41b92c9d1 compilation passes return third value: the continuation environment
* 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.

275baf0113 guile-config rebased on top of pkg-config
* configure.in:
* meta/Makefile.am (EXTRA_DIST): Remove guile-config.in bits.

* meta/guile-config: Reimplement to work on top of pkg-config. This lets
  guile-config not be substed by configure.

* meta/uninstalled-env.in: Remove the path to guile-config, belatedly.
  Set the pkg-config path correctly.

da8b47478e Avoid uses of deprecated forms in the VM code.
Reported by Daniel Kraft <d@domob.eu>.

* libguile/frames.c, libguile/vm.c: Include <stdlib.h>, use `size_t'
  instead of `scm_sizet'.

* libguile/objcodes.c, libguile/programs.c, libguile/vm-engine.c,

aa49787b5e Improved handling of callers cache in (system xref).
* We cache callees in each module, and keep a list of modified

0b6d8fdc28 allow building against uninstalled guile; move some things to meta/
* README: Add more info about building against an uninstalled Guile.

* meta/: New directory. The proximate cause of its creation is that I
  want to be able to build external packages against uninstalled Guile,
  and to do that I need guile-tools in the PATH, but I don't want
  $top_builddir/libtool in the path. But it seems like a good
  reorganization, for things that are /about/ Guile: pkg-config files, m4
  files, guile-config... then we also include uninstalled info: the
  environment, the pre-inst-guile script, etc.

* meta/guile-1.8-uninstalled.pc.in: New pkg-config template. pkg-config
  prefers -uninstalled pkg-config files, if they are in its path.

* meta/Makefile.am:
* meta/ChangeLog-2008:
* meta/gdb-uninstalled-guile.in:
* meta/guile-1.8.pc.in:
* meta/guile-config.in:

7ca96180f0 Run the stack calibration script before running the compiler.
* am/guilec (.scm.go): Use `pre-inst-guile' and load
  `stack-limit-calibration.scm'.  This is particularly useful when
  building the first `.go' files where the compiler is run using the
  interpreter, which may end up using a lot of stack space.

* libguile/Makefile.am (BUILT_SOURCES): Add
  `stack-limit-calibration.scm'.
  (TESTS, TESTS_ENVIRONMENT): Remove.
