    (ice-9 optargs) based on the new lambda* work
    * module/ice-9/optargs.scm (let-optional, let-optional*, let-keywords)
      (let-keywords*): Implement in terms of parse-lambda-case, so all the
      logic is in one place.
      (lambda*): Re-export from the default environment -- it's all in the
      VM now :-))
      (define*, define*-public, defmacro*, defmacro*-public): Implement with

    lambda* in psyntax
    * module/ice-9/psyntax.scm (build-lambda-case): Take an "inits" arg.
      Also work around a nasty memoizer bug: see
      (lambda*): Implement in psyntax, in the default environment. Exciting
    * module/ice-9/psyntax-pp.scm: Regenerated.
    * module/ice-9/optargs.scm (parse-lambda-case): Helper for lambda* when
      we're running under the interpreter.

    separate "inits" field in <lambda-case>; compile fixes for inits, kwargs
    * 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
    * module/language/tree-il/analyze.scm (analyze-lexicals): Analyze
      lexicals in the <lambda-case> init expressions as well. Fix keyword
    * 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):

Author: Andy Wingo <address@hidden>
Date:   Fri Oct 23 15:47:08 2009 +0200

    add some optargs tests
    * libguile/modules.c (scm_module_lookup, scm_lookup): Throw to
      'unbound-variable, like eval.i.c does.
    * test-suite/tests/optargs.test: Add an optargs test. Run optargs tests
      under both the VM and the interpreter.

Author: Andy Wingo <address@hidden>
Date:   Fri Oct 23 15:44:22 2009 +0200

    vm support for optional/kwarg init code, and bugfixes
    * libguile/vm-i-system.c (local-bound?, long-local-bound?)
      (variable-bound?): New instructions, push #f unless the local is
      bound. You can get unbound locals from optional arguments.
      (bind-optionals/shuffle): A number of bugfixes.
      (bind-kwargs): Bugfixes. If we enocunter an improper kwarg list but
      the procedure has a rest argument, just stop kwarg processing, but
      without an error.
      Renumbered ops.
    * libguile/_scm.h (SCM_OBJCODE_MAJOR_VERSION): Bump.

Author: Andy Wingo <address@hidden>
Date:   Mon Oct 19 22:13:08 2009 +0200

    more work towards compiling and interpreting keyword args
    * libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bumparoo
    * libguile/vm-i-system.c (push-rest, bind-rest): Logically there are
      actually two rest binders -- one that pops, conses, and pushes, and
      one that pops, conses, and local-sets. The latter is used on keyword
      arguments, because the keyword arguments themselves have been shuffled
      up on the stack. Renumber ops again.
    * module/language/tree-il/compile-glil.scm (flatten): Attempt to handle
      compilation of lambda-case with keyword arguments. Might need some
    * module/ice-9/psyntax.scm (build-lambda-case): An attempt to handle the
      interpreted case correctly. This might need a couple iterations, but
      at least it looks like the compile-glil code.
    * module/ice-9/psyntax-pp.scm: Regenerated.
    * module/language/glil.scm (<glil>): Rename "rest?" to "rest" in
      <glil-opt-prelude> and <glil-kw-prelude>, as it is no longer a simple
      boolean, but if true is an integer: the index of the local variable to
      which the rest should be bound.
    * module/language/glil/compile-assembly.scm (glil->assembly): Adapt to
      "rest" vs "rest?". In the keyword case, use "bind-rest" instead of
    * test-suite/tests/tree-il.test: Update for opt-prelude change.

    finish support for optional & keyword args; update ecmascript compiler
    * libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
    * libguile/vm-i-system.c (br-if-nargs-ne, br-if-args-lt)
      (br-if-nargs-gt): New instructions, for use by different lambda cases.
      (bind-optionals, bind-optionals/shuffle, bind-kwargs): New
      instructions, for binding optional and keyword arguments. Renumber
      other ops.
    * module/language/ecmascript/compile-tree-il.scm (comp, comp-body):
      Update for new tree-il. Use the new optional argument mechanism
      instead of emulating it with rest arguments.
    * module/language/glil/compile-assembly.scm (glil->assembly): Tweaks for
      optional and keyword argument compilation.
    * module/language/tree-il.scm (parse-tree-il, unparse-tree-il): Make the
      else case optional, in the s-expression serialization of tree-il.
    * module/language/tree-il/compile-glil.scm (flatten): Handle all of the
      lambda-case capabilities.

    fix brainfuck for new tree-il, and add tests
    * test-suite/
    * 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.

    tree-il support for case-lambda
    * module/language/tree-il.scm (<lambda>, <lambda-case>): Split lambda
      into the lambda itself, denoting the procedure, and lambda-case,
      denoting a particular arity case. Lambda-case is fairly featureful,
      and has not yet been fully tested.
      (<let-values>): Use a <lambda-case> as the binding expression. Seems
      to suit the purpose well.
      Adapt parsers, unparsers, traversal operators, etc. Sometimes in this
      first version we assume there are no optional args, rest args, or a
    * module/language/tree-il/analyze.scm (analyze-lexicals): Adapt for the
      new case-lambda regime. Fairly well commented. It actually simplifies
      (report-unused-variables): Update for new tree-il.
    * module/language/tree-il/compile-glil.scm: Adapt for the new tree-il.
      There are some first stabs here at proper case-lambda compilation, but
      they are untested as of yet.
    * module/language/tree-il/inline.scm (inline!): Rework so we can
      recurse on a single node; though these transformations are strictly
      reductive, so they should complete in bounded time. Simplify
      accordingly, and adapt to case-lambda. Oh, and we handle lambda->let
      in not just the nullary case.
    * module/ice-9/psyntax.scm (build-simple-lambda, build-case-lambda)
      (build-lambda-case): New constructors. The idea is that after syntax
      expansion, we shouldn't have to deal with improper lists any more.
      Build-simple-lambda is a shortcut for the common case. The others are
      not fully exercised yet. Adapt callers.
      (syntax): Add some debugging in the lambda case. I don't fully
      understand this, but in practice we don't seem to see rest args here.
      (lambda): Inline chi-lambda-clause, and adapt for build-simple-lambda.
    * module/ice-9/psyntax-pp.scm: Regenerated.
    * test-suite/tests/tree-il.test: Update tests for new tree-il lambda
      format, and to expect post-prelude labels for all glil programs.

    procedure property efficiency tweak
    * libguile/procprop.c (scm_procedure_property)
      scm_set_procedure_property_x): Fix to not call
      scm_procedure_properties(), and thus to avoid consing up the arity as

Author: Andy Wingo <address@hidden>
Date:   Tue Oct 13 23:55:58 2009 +0200

    flesh out glil support for optional and keyword arguments
    * libguile/vm-i-system.c (bind-rest): Renamed from push-rest-list.
      (reserve-locals): Change so that instead of reserving space for some
      additional number of locals, reserve-locals takes the absolute number
      of locals, including the arguments.
    * module/language/glil.scm (<glil-std-prelude>, <glil-opt-prelude>)
      (<glil-kw-prelude>): New GLIL constructs, to replace <glil-arity>.
    * module/language/glil/compile-assembly.scm (glil->assembly): Compile
      the new preludes. Some instructions are not yet implemented, though.
    * module/language/tree-il/analyze.scm (analyze-lexicals): The nlocs for
      a lambda will now be the total number of locals, including arguments.
    * module/language/tree-il/compile-glil.scm (flatten-lambda): Update to
      write the new prelude.
    * module/system/vm/program.scm (program-bindings-for-ip): If a given
      index doesn't have a binding at the ip given, don't cons it on the
      resulting list.
    * test-suite/tests/tree-il.test: Update for GLIL changes.

Date:   Tue Oct 13 23:45:22 2009 +0200

    de-nargs struct scm_objcode; procedure-property refactor
    * libguile/objcodes.h (struct scm_objcode): Remove nargs, nrest, and
      nlocs, as they are no longer needed. Also obviates the need for a
      padding word.
    * libguile/procs.c (scm_thunk_p): Use scm_i_program_arity for programs.
    * libguile/procprop.c (scm_i_procedure_arity): Use scm_i_program_arity
      for programs.
      (scm_procedure_properties, scm_set_procedure_properties_x)
      (scm_procedure_property, scm_set_procedure_property_x): Rework so that
      non-closure properties are stored directly in a weak hash, instead of
      needing a weak hash of "stand-in" closures to hold the properties. Fix
      docstrings also.
    * libguile/root.h (scm_stand_in_procs): Remove from the scm_sys_protects
      set. Actually with libGC, we should be able to store the elements of
      scm_sys_protects directly as global variables.
    * libguile/gc.c (scm_init_storage): Remove scm_stand_in_procs
    * libguile/programs.c (scm_i_program_arity): New private accessor, tries
      to determine the "minimum arity" of a program.
    * libguile/vm.c (really_make_boot_program): Adapt to changes in
      struct scm_objcode.
    * module/language/assembly.scm (*program-header-len*, byte-length):
    * module/language/assembly/compile-bytecode.scm (write-bytecode):
    * module/language/assembly/decompile-bytecode.scm (decode-load-program):
    * module/language/assembly/disassemble.scm (disassemble-load-program):
      Adapt to changes in objcode.
    * module/system/xref.scm (program-callee-rev-vars): Adapt to changes in
    * module/language/glil.scm: Remove nargs, nrest, and nlocs from
    * module/language/glil/compile-assembly.scm (make-meta, glil->assembly):
    * module/language/glil/decompile-assembly.scm (decompile-toplevel):
      (decompile-load-program): Adapt to changes in GLIL and assembly.
    * module/language/tree-il/compile-glil.scm (flatten-lambda): Adapt to
      changes in GLIL.
    * test-suite/tests/asm-to-bytecode.test: Adapt to assembly and bytecode
    * test-suite/tests/tree-il.test: Adapt to GLIL changes.

    callees now check their args, cons rest list, reserve locals
    * gdbinit: Ignore SIGPWR and SIGXCPU, which the BDW GC seems to use.
    * libguile/vm-engine.h (FETCH_WIDTH): Remove unused macro.
      (INIT_ARGS, INIT_FRAME): Remove; callees now check their args and
      reserve space for their locals.
    * libguile/vm-engine.c:
    * libguile/vm-i-system.c: Turn on callee arg checking and local
      reservation. Seems to work!

    callees reserve their own local vars
    * libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
    * libguile/vm-i-system.c (reserve-locals): New instruction, to reserve
      space for local vars. Other ops renumbered.
    * module/language/tree-il/compile-glil.scm (flatten-lambda): Emit
      reserve-locals instructions as necessary.
    * test-suite/tests/tree-il.test: Update to expect reserve-locals as

    runtime and debugging support for callee-parsed procedure args
    * libguile/objcodes.h: Bump for metadata format change.
    * libguile/frames.h: Rework so we don't frob the program's nargs, nlocs,
      etc at runtime. Instead we don't really know what's a local var, an
      argument, or an intermediate value. It's a little unfortunate, but
      this will allow for case-lambda, and eventually for good polymorphic
      generic dispatch; and the nlocs etc can be heuristically
      reconstructed. Such a reconstruction would be better done at the
      Scheme level, though.
      (SCM_FRAME_STACK_ADDRESS): New macro, the pointer to the base of the
      stack elements (not counting the program).
      (SCM_FRAME_UPPER_ADDRESS): Repurpose to be the address of the last
      element in the bookkeeping part of the stack -- i.e. to point to the
      return address.
    * libguile/vm-engine.h:
    * libguile/vm-i-system.c: Adapt to removal of stack_base. Though we
      still detect stack-smashing underflow, we don't do so as precisely as
      we did before, because now we only detect overwriting of the frame
    * libguile/vm-engine.c (vm_engine): Remove the stack_base variable. It
      is unnecessary, and difficult to keep track of in the face of
      case-lambda. Also fix miscommented "ra" and "mvra" pushes. Push the
      vp->ip as the first ra...
    * libguile/vm-i-system.c (halt): ...because here we can restore the
      vp->ip instead of setting ip to 0. Allows us to introspect ips all
      down the stack, including in recursive VM invocations.
    * libguile/frames.h:
    * libguile/frames.c (scm_vm_frame_stack): Removed, because it's getting
      more difficult to tell what's an argument and what's a temporary stack
      (scm_vm_frame_num_locals): New accessor.
      (scm_vm_frame_instruction_pointer): New accessor.
      (scm_vm_frame_arguments): Defer to an implementation in Scheme.
      (scm_vm_frame_num_locals scm_vm_frame_local_ref)
      (scm_vm_frame_local_set_x): Since we can get not-yet-active frames on
      the stack now, with our current calling convention, we have to add a
      heuristic here to jump over those frames -- because frames have
      pointers in them, not Scheme values.
    * libguile/programs.h:
    * libguile/programs.c (scm_program_arity): Remove, in favor of..
      (scm_program_arities): ...this, which a list of arities, in a new
      format, occupying a slot in the metadata.
    * module/language/assembly/decompile-bytecode.scm (decode-load-program):
      Fix mv-call decompilation.
    * module/system/vm/frame.scm (vm-frame-bindings, vm-frame-binding-ref)
      (vm-frame-binding-set!): New functions, to access bindings by name in
      a frame.
      (vm-frame-arguments): Function now implemented in Scheme. Commented
      fairly extensively.
    * module/system/vm/program.scm (program-bindings-by-index)
      (program-bindings-for-ip): New accessors, parsing the program bindings
      metadata into something more useful.
      (program-arities, program-arguments): In a case-lambda world, we have
      to assume that programs can have multiple arities. But it's tough to
      detect this algorithmically; instead we're going to require that the
      program metadata include information about the arities, and the parts
      of the program that that metadata applies to.
      (program-lambda-list): New accessor.
      (write-program): Show multiple arities.
    * module/language/glil/compile-assembly.scm (glil->assembly): Add
      "arities" to the state of the compiler, and add arities entries as

    steps on the way to have the callee check the number of arguments
    * libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
    * libguile/vm-i-system.c (assert-nargs-ee, assert-nargs-ge)
      (push-rest-list): New instructions, which for now don't actually do
      anything. Renumber the rest of the ops in this file.
    * module/language/glil.scm (<glil-arity>): New GLIL type, an entity that
      checks the number of args for a block, optionally consing a rest list,
      and either branching or erroring if the arity doesn't match.
    * module/language/glil/compile-assembly.scm (glil->assembly): Compile
      <glil-arity> to assembly. Some of these VM ops are not implemented --
      notably the branching case.
    * module/language/tree-il/compile-glil.scm (flatten-lambda): Emit
    * test-suite/tests/tree-il.test: Update.

    compilation enviroments are always modules; simplifications & refactorings
    * 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
    * 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
    * 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').

      Remove, as the only thing that needed it (language readers) now get
      the environment as an argument.
      (read-and-compile, compile): Rework for no *compilation-environment*,
      and default the environment using the define* mechanism.
    * module/language/tree-il/analyze.scm (env-module): Hack around the lack
      of a current compilation module. Will fix this in the next commit so
      that the environment is always valid.

    R5RS compilation is supported via compiling Scheme within an R5RS
    Elisp will be supported when we merge in Daniel's work.

    Language-specific case-conversion doesn't honor locale
    Libunistring uses a function uc_locale_language to extract the
    current language from the locale information.  It does this by calling
    setlocale.  This makes incompatible with Guile functions that use the
    locale_t thread-specific locale API, because the values returned by the
    call to setlocale ignore the locale set by uselocale.
    As a workaround, this patch extracts the language from the locale_t
    structure's __names field.
    A more complete solution is needed.  Perhaps that solution would test
    that the __names field exists in the configure step and revert to
    !USE_GNU_LOCALE_API in that case.

      same job as uc_locale_language but is compatible with uselocale

    GDS usability: operation without a mouse
    Derek Peschel provided this patch and described it as follows.
    "Most of the time I use Terminal in OS X, rather than xterm.  I also don't
    bother with the GUI versions of Emacs.  So unfortunately I have no mouse
    support in Emacs.  Also the system I'm testing Guile on thinks my terminal
    doesn't support color and I haven't fixed it yet.  The attached patch makes
    GDS more usable for me.
    "With no mouse, the "[click here to show error stack]" design is very
    inconvenient.  You added a C-M (return) binding at some point.  I copied
    that, but I also changed the message to show it.  And I made the return
    work when the cursor is after the right bracket."
    * emacs/gds-scheme.el (gds-display-results): Make "click here" message
      more helpful for people without mice.  Also extend text properties
      so that a RET key press works at the end of that line.

    Fix omission of VM frames from backtrace
    From the time when a #<program> was a SMOB, really_make_boot_program
    in vm.c was still using SCM_SET_SMOB_FLAGS to set the
    SCM_F_PROGRAM_IS_BOOT flag - which meant that it was setting flag
    1<<32 :-) which obviously was then missed by the SCM_PROGRAM_IS_BOOT
    calls in stacks.c.
    * libguile/programs.h (SCM_F_PROGRAM_IS_BOOT): Use a less significant
      bit for this flag, now that programs use a tc7 type.
    * libguile/vm.c (really_make_boot_program): Don't use
      SCM_SET_SMOB_FLAGS, now that programs aren't SMOBs.

      macro-expansion frame.  (Missing this decrement will cause a "stack
      count incorrect" warning but is actually benign, as it only means
      that scm_make_stack allocates a bit more space for the stack than it
      really needs.)
      (read_frames): Increment count of remaining unused frames, when
      cutting out a macro transformer application frame.  (Missing this
      increment could cause the "stack count incorrect" warning, and could
      make read_frames think it's filled up all the available stack frames
      when there's actually still one frame unused; this wasn't benign,
      because it could cause information to be missing from a stack
