86bc3da9e0 Rebase SRFI-35 on top of (ice-9 exceptions)
* module/ice-9/exceptions.scm (exception-type?): New export.
* module/srfi/srfi-35.scm: Rewrite in terms of (ice-9 exceptions).
2019-11-04 15:18:57 +01:00
Andy Wingo
54ab2175f9 Add (ice-9 exceptions) module
* module/ice-9/exceptions.scm: New file, derived from (rnrs
  conditions).  Perhaps unadvisedly, in this file I've renamed a number
  of the identifiers.  I have never found that the R6RS identifiers made
  sense to me.  For now this is an internal module that R6RS and SRFI-35
  will be based on.
* module/Makefile.am (SOURCES): Add the new file.
* module/rnrs/conditions.scm (rnrs): Export renamed identifiers
  from (ice-9 exceptions).
2019-11-03 21:37:02 +01:00
Andy Wingo
90d52a9e1d Add `record-type-has-parent?'.
* module/ice-9/boot-9.scm (record-type-has-parent?): New function.
* module/srfi/srfi-35.scm (condition-type?): Use it.

9f1a671734 Remove circularity in r6rs by rebasing conditions on core records
* module/rnrs/conditions.scm: Use core record facilities to define the
  base condition types, define-condition-type, and the standard
  condition hierarchy.
  (simple-condition?): Rename from condition-internal?.
* module/rnrs/exceptions.scm: Move `raise' definition here, out from the
  procedural records layer.
  (format-simple-condition): Reimplement in a simpler way, hopefully
  producing the same output.
* module/rnrs/records/procedural.scm:
* module/rnrs/records/inspection.scm: Import the exceptions and
  conditions modules, and use the normal raise function.

73d0a3bccb Rebase R6RS records on top of core records
* module/ice-9/boot-9.scm (record-type-uid): New accessor.
  (make-record-type): Record UID in record type properties.
* module/rnrs/conditions.scm (define-condition-type): Fix invalid
  invocation of make-record-type.
* module/rnrs/records/inspection.scm: Rewrite to use core record
  inspection facilities.
* module/rnrs/records/procedural.scm: Rewrite to use core
  make-record-type.  Incidentally the result is that instances of
  derived R6RS record types are now flat instead of nested.
* test-suite/tests/r6rs-records-procedural.test
  ("make-record-type-descriptor"): Relax a couple condition type checks,
  while we redo the exception system.

315fabdfe7 Add support for immutable fields in core records
* module/ice-9/boot-9.scm (make-record-type): Allow (mutable NAME)
  or (immutable NAME) as a field name, and record field mutability in a
  bitfield.
  (record-modifier): Throw an error if the field isn't mutable.
* test-suite/tests/records.test ("records"): Add tests.
* doc/ref/api-data.texi (Records): Update.

  record-type-final?, with the opposite sense.
  (record-type-opaque?): New accessor.

  opposite meaning.  Add #:opaque? arg.

99a95383cf Rebase srfi-35 conditions on top of make-record-type
* module/srfi/srfi-35.scm: Import (ice-9 match), and remove now-unused
  srfi-1 import.
  (print-condition): Print more like records, as appears to be the
  intention.
  (&condition): Define using make-record-type.  Adapt all callers.
  Also, compound conditions are now a disjoint type, handled specially
  by condition-ref, condition?, and so on.

  subcondition was initialized without initializers for all of its
  fields.

f060f1a4e6 Record accessors respect subtyping
* module/ice-9/boot-9.scm (make-record-type): Don't allow subtyping of
  final types.
  (%record-type-error): Remove helper.
  (record-accessor, record-modifier): Use computed record type
  predicate, to allow for subtyping.
  (define-record-type): Adapt to %record-type-error going away; these
  types are final so no accessor adaptation is needed.
* test-suite/tests/records.test: Add tests.
* doc/ref/api-data.texi (Records): Update.

4e89d0c061 Use "G_" as the conventional alias for gettext
Since the change in 2.2 noted in the NEWS as "Fix literal matching for
module-bound literals", defining `_' makes `syntax-rules' and `match'
fail to recognize `_' as the catch-all literal.  This change adapts the
recommendations to current practice in 2.2, as users have had to adapt
to this change.

* doc/ref/api-i18n.texi (Gettext Support): Update documentation.
* module/language/tree-il/analyze.scm (proc-ref?, gettext?): G_ is the
  conventional abbreviation, not _.
* test-suite/tests/tree-il.test: Adapt.
* module/ice-9/command-line.scm: Use G_ instead of _.

887aac28d2 At optimization level -O3, seal declarative module-private bindings
* module/language/tree-il/letrectify.scm (compute-private-toplevels):
  New function; computes the subset of declarative bindings that are
  private to a module.  If the module exports a macro, all bindings are
  public, as we have no way to know what binding might be exported.
 (letrectify): Add #:seal-private-bindings? keyword arg.  If true, avoid
  making boxes for private definitions.

a2f5f9eda4 Fix bug in CSE auxiliary definitions
* module/language/cps/cse.scm (compute-equivalent-subexpressions): When
  CSE sees a definition like `(cons a b)', it will also record an
  "auxiliary definition" for `(car x)', where x is the variable defined
  by the cons, whereby calling `(car x)' can reduce to `a' if there is
  no intervening effect that clobbers the definitions.  However, when
  the successor of the cons is a control-flow join, then any variables
  defined there have multiple definitions.  It's incorrect to add the
  aux definition in that case.
* test-suite/tests/compiler.test ("cse auxiliary definitions"): New
  test.

2053592214 Allow mixed local definitions and expressions
This change to the expander allows mixed local definitions and
expressions.  The expansion turns:

  (let () (a) (define (b) 42) (b) (b))

into:

  (let ()
    (letrec* ((t0 (begin (a) (if #f #f)))
              (b (lambda () 42)))
      (b)))

Which is to say, expressions that precede definitions are expanded as
definitions of a temporary via (begin EXP (if #f #f)).

* module/ice-9/psyntax.scm (expand-body): Allow mixed definitions and
  expressions.
* module/ice-9/psyntax-pp.scm: Regenerate.

Add "mod" field to <toplevel-ref>, <toplevel-set>, and
