chars, fixed.

 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 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.

 2008-09-26 02:46:07 -04:00
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.

 2008-09-23 01:49:06 -04:00
Abdulaziz Ghuloum df4cb7a6ce fixed an off-by-one bug in ffi callbacks. 2008-09-23 00:24:41 -04:00
Abdulaziz Ghuloum 09657334c0 fixed autoconf so that ffi.h and libffi are checked iff ffi is 
enabled.  Also made prep-callback return #f if libffi does not
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
Abdulaziz Ghuloum 8e750562d6 - Added memory operations on pointer types for setting and accessing 
char, short, int, and long values from pointer arrays.
 2008-09-13 07:49:17 -07:00
Abdulaziz Ghuloum e05e84d1c2 Added dlopen, dlclose, dlerror, dlsym, malloc, and free to 
(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.
 2008-09-10 06:35:18 -07:00

Abdulaziz Ghuloum c597e7a4b3 Added option for searching for socket and nanosleep in libraries 
-lsocket and -lrt (makes it work on SunOS).
 2008-09-08 14:43:47 -07:00
Abdulaziz Ghuloum afc9bff07f - added experimental pointer manipulation primitives. 2008-09-06 06:01:39 -07:00
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

are complex.
 2008-08-11 10:37:05 -07:00

the print-unicode parameter.
 2008-08-10 11:50:39 -07:00

Abdulaziz Ghuloum 2ad6d9bddf strings containing non-ascii characters are written using either 
hex escaping or as-is depending on the value of the print-unicode
parameter.
 2008-08-10 11:03:09 -07:00
Abdulaziz Ghuloum 22d216f9ed - fixed a problem with loading an empty file.

 2008-08-10 10:46:24 -07:00

Abdulaziz Ghuloum 7bacb4a0a5 Added string-downcase and string-upcase. String-downcase does not 
handle greek-final-sigma properly.
 2008-08-09 07:12:22 -07:00
Abdulaziz Ghuloum e24356eb4a scheme-script is now its own program; it does not fork and exec 
ikarus, and therefore does not interfere with ikarus's command line
parsing.
