Before:
> ,c (set! x 3)
0 (make-int8 3) ;; 3
2 (link "x")
5 (variable-set)
> ,c (define x 3)
0 (make-int8 3) ;; 3
2 (link "x")
5 (variable-set)
After:
> ,c (define x 3)
0 (make-int8 3) ;; 3
2 (define "x")
5 (variable-set)
* src/vm_loader.c (link): `link' now errors if the variable is undefined.
This corresponds with desired behavior, for both `ref' and `set'
operations, for scheme. It's not what elisp wants, though. Perhaps
elisp linking needs another instruction.
(define): New instruction, the same as calling scm_define(), basically.
* module/language/scheme/translate.scm (trans-pair): Don't try to look up
an existing variable definition when translating `define'; instead use
the special-purpose lookup from ghil.scm's `ghil-define'.
* module/system/il/compile.scm (codegen): Compile to a different kind of
variable access from `set!', specifically via passing 'define as the op
to `make-glil-var'.
* module/system/il/ghil.scm (ghil-lookup): Don't add to the module table
when compiling variable sets via `set!'.
(ghil-define): New procedure, for looking up variables for `define'.
* module/system/vm/assemble.scm (<vdefine>): New record: a new
instruction type.
(codegen): Compile `define' module vars into <vdefine>.
(dump-object!): <vdefine> == `define'.
* module/language/scheme/translate.scm (trans-pair): Add a guard to only
allow `define' at the top level; other defines are already filtered out
via trans-body.
* module/system/il/ghil.scm (ghil-env-toplevel?): Export, and fix.
* module/system/base/compile.scm:
* module/system/il/ghil.scm:
* module/system/repl/describe.scm:
* module/system/vm/core.scm:
* module/system/vm/frame.scm:
* module/system/vm/trace.scm: Explicitly list exports in the module
declaration instead of using define-public.
* module/system/base/compile.scm: Export cenv? also.
* module/system/base/syntax.scm: Clean up vestiges of the old structure
code. Make accessors defined as foo? instead of <foo>?.
* module/system/il/glil.scm:
* module/system/il/ghil.scm: Remove <foo>-1 accessors, since we have
named accessors.
* module/system/repl/common.scm (repl-prompt): Return a string instead of
outputting to the port, for better readline integration.
* module/system/repl/repl.scm (meta-reader, prompting-meta-read)
(start-repl): Integrate with (ice-9 readline) via the current-reader
fluid and the repl-reader function, both from boot-9.scm.
* module/system/repl/command.scm (system): Declare exports in the module
declaration.
* module/system/repl/repl.scm (start-repl): If the evaluation returns
multiple values, print them separately.
* module/system/base/syntax.scm (define-record): Rebase to implement on
top of Guile's records, which are the substrate of srfi-9's records.
(%compute-initargs): Rename from %make-struct, just return the list of
values.
(get-slot, set-slot!, slot): Removed, no longer used.
(record-case): Allow slots of the form (MYNAME SLOTNAME), which binds
SLOTNAME to MYNAME (instead of SLOTNAME to SLOTNAME).
(record-case, record?): No more ice-9 match!
* module/system/il/compile.scm (codegen): Tweaks so that the new record
code works.
* module/system/il/ghil.scm: Fix some slot references.
* module/system/vm/assemble.scm (preprocess, codegen): Remove calls to
`slot'.
(codegen): Fix some slot references.
* module/system/base/syntax.scm (define-record): Define the accessors as
procedures-with-setters, not just as getters.
* module/system/il/compile.scm (optimize): This function was bitrotten
since the addition of source locations in
cb4cca12e7. Untested attempts to
de-bitrot it. Dedottify as well.
* module/system/il/ghil.scm:
* module/system/il/glil.scm (unparse):
* module/system/vm/debug.scm (debugger-repl): Ongoing dedottification.
* module/system/base/syntax.scm (define-record): Define named accessors,
to prepare the code for srfi-9 records switchover.
* module/system/il/ghil.scm:
* module/system/il/glil.scm: Export a bunch of named accessors.
* module/language/scheme/translate.scm: Refactor use of `match' to use
`pmatch'. Relatively straightforward.
* module/system/base/pmatch.scm (ppat): Fix some copy-n-paste bugs: the _
rule, the quote rule.
* module/system/base/Makefile.am: Add pmatch.scm.
* module/system/base/pmatch.scm: New file, taken from Dan Friedman's
alpha-kanren paper. Implements a less magical match syntax, pmatch.
* module/system/vm/assemble.scm: No more need for (ice-9 match).
* module/system/vm/conv.scm (code-pack, code->object): Change to use
pmatch.
* module/system/base/syntax.scm (record-case): Capture the match macro.
* module/system/il/glil.scm:
* module/system/il/compile.scm: Convert to record-case.
* 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/system/base/syntax.scm (record?): Temporarily export this thing,
so that code will remain correct when I change to srfi-9 records.
* module/system/vm/assemble.scm: Convert to use record-case.
* module/system/base/syntax.scm (system): Don't re-export receive or
and-let*; modules should explicitly import these if they want to. Don't
export an empty stack-catch definition!
* module/system/repl/command.scm (system): Pull in and-let*.
* module/system/vm/disasm.scm (system): Don't import and-let*.
* benchmark/lib.scm (fibo): Make fibo actually a fibonacci sequence.
* module/system/base/syntax.scm (system): Forward-declare all exports.
(expand-symbol, slot): Rewrite expand-symbol to expand to a
non-recursive invocation of `slot', so that in the future when we get
rid of this syntax, the replacement will be more palatable to the eyes.
* module/language/scheme/translate.scm (¤t-macros): Removed.
(¤t-macro-module): Removed.
(&compile-time-module): New.
(eval-at-compile-time): New.
(translate): Initialize `&compile-time-module'.
(expand-macro)[use-syntax]: New case.
[begin let...]: Don't expand these built-in macros.
[else]: Rewrote the macro detection and invocation logic. Invoke macro
transformers in the current compile-time module.
(trans): Let `expand-macro' raise an exception if needed.
(trans-pair)[defmacro define-macro]: Evaluate the macro definition in
the compile-time module.
* testsuite/t-match.scm: Use `use-syntax' instead of `use-modules' for
`(ice-9 match)' and `(srfi srfi-9)'.
* testsuite/t-records.scm: Likewise.
