Abdulaziz Ghuloum f570ea8c2a - interface between write/display and custom struct writers is 
changed in order to allow large structures (e.g., libraries,
  syntax objects, etc.) to print efficiently.  This is done by only
  traversing the parts of the structure that will actually be
  printed, rather than traversing the whole data structure (which is
  what write/display used to do).  Pretty-print should be fixed in a
  similar manner (TODO).

 2008-10-13 02:40:26 -04:00
Abdulaziz Ghuloum 1be0f2af6e - changed foreign accessors and mutator names to have '-c-' in their 
names as suggested by Ken Dickey.
 2008-10-12 02:06:25 -04:00
Abdulaziz Ghuloum 811c94361b - fixed bugs in pass-specify-rep where some (known) types were 
unhandled causing compile time errors.

  of the (ikarus) library)
- freshened up the bootfiles for both 32- and 64-bit version of
  ikarus.
 2008-10-12 01:15:20 -04:00
Abdulaziz Ghuloum 69c62649cc - defined RTLD_LOCAL for cygwin (possibly incorrect) 
- added a missing save to a callee-save register (%edi) 
  when entering/reentering to Scheme which caused Ikarus
  not to run properly depending on whether or not gcc places
  the pcb in %edi or not during Scheme execution.
- updated lab/test-ffi.ss to use the new names for foreign
  types, etc.
 2008-10-07 02:46:56 -04:00
Abdulaziz Ghuloum 1e5e516b08 - added (ikarus foreign) library that should be used instead of 
(ikarus system $foreign).
- changed the names of some of the pointer primitives
- changed the name of the procedure make-ffi to make-callout
- updated examples and libraries to conform with new names
- updated the users guide to provide a complete description of 
  the (ikarus foreign) library
- updated list of missing R6RS features in the users guide

Abdulaziz Ghuloum 997c75fabb fixed a bug that caused (- <bignum> <bignum>) to crash or yield 
incorrect result if gc is triggered while allocating the resulting
bignum.

Abdulaziz Ghuloum cd4e12be68 One can now create (at runtime) objective-c classes and add methods 
to them to get them to do things.  See lab/objc-create-class.ss for
a cute example.

Abdulaziz Ghuloum 0a7a3a8266 made load feel like a top-level by consuming the contents of the 
given file one expression at a time.  Most notable difference is 
observed when the loaded file captures a conitnuation in one
expression.  Re-invoking this continuation should evaluate the 
next expression that has not been evaluated yet, and not the
expression following the call/cc.

Abdulaziz Ghuloum 89d9a472a5 "darwin" is no longer hardcoded in lib/ypsilon-compat.ikarus.ss, 
instead, it is obtained from the target info that autoconf
generates.

support closures.
 2008-09-22 21:55:05 -04:00

Abdulaziz Ghuloum 9f2d7484ab fixed uint/ulong pointer ref bug (and added appropriate tests). 2008-09-14 00:38:59 -07:00
Abdulaziz Ghuloum 58d937c520 upgraded to using latest versions of autoconf, aclocal, and m4. 2008-09-13 15:16:14 -07:00

(ikarus system $foreign).
 2008-09-12 14:22:57 -07:00
Abdulaziz Ghuloum 30cd6a2de8 made environment-symbols work on the interaction-environment. 2008-09-10 11:02:42 -07:00
Abdulaziz Ghuloum 0b017898a8 - minor change to how export (with renaming) is parsed. When you 
rename from-name to to-name, the from-name is now treated as an
  identifier while the to-name is treated as a symbol.
 2008-09-10 08:17:18 -07:00
Abdulaziz Ghuloum fcef21c693 - Added (environment-symbols <env>) which returns a list of symbols 
exported by the environment.  Try 
  > (environment-symbols (environment '(rnrs)))

- Added an internal export mechanism so that identifiers can be
  exported from within a library.  The syntax is the same:
    (export export-spec* ...) 
  when appears in a library's top level, adds the export specs to
  the set of exported identifiers.  So, one can do:
    (library (A) 
      (export)
      (import (ikarus))
      (export a)
      (define a 17))
  When appearing in non-library definition context, the export form
  is ignored.

Abdulaziz Ghuloum 814c797633 - removed bset/h instruction from the compiler (it was rarely used 
and not implemented 100% correctly)
- fixed parameterize to allow (parameterize () def ... exp exp ...)
 2008-09-06 04:17:20 -07:00
Abdulaziz Ghuloum 9b9464229a - fixed how stack overflow check is performed (now using unsigned 
arithmetic to compare the stack pointer with the redline).
- disabled stack overflow check elimination due to a bug in the
  logic that assumes primitive calls are not recursive.
 2008-08-13 22:28:22 -07:00
Abdulaziz Ghuloum b9085e15da - more work on trig functions 
- mkstx now checks that double wraps are not merged incorrectly

hex escaping or as-is depending on the value of the print-unicode
parameter.

Abdulaziz Ghuloum 7bacb4a0a5 Added string-downcase and string-upcase. String-downcase does not 
handle greek-final-sigma properly.
