Abdulaziz Ghuloum 45346ef865 - Added cp0! including:
- (optimize-level [0,1,2])  and  ikarus -O[0,1,2]
       where -O0 = no optimizations
             -O1 = using old optimizer
             -O2 = using the new cp0 optimizer
       defaults to -O1 for now.
   - (cp0-size-limit n) which is the limit of the residual size for
     each inlining attempt
   - (cp0-effort-limit n) which is the limit on the effort expended 
     for each inlining attempt
   
- Rewrote the syntax-match macro to make use of the same technology
  used in syntax-case itself resulting in reduced code size.

- Added (system-value <symbol>) which returns the system value.
  E.g., (system-value 'car) => #<procedure car>
  This is pretty much the same as 
    (eval <symbol> (environment '(ikarus)))
  except that it does not involve compiling the expression or 
  consulting the library/expander systems.

- Fixed the fasl loader to make it understand complex numbers.
2008-06-28 02:25:44 -07:00
Abdulaziz Ghuloum 7d9ed176ac More work on cp0 which can now swallow the compiler but cannot yet
fold any primitives.
2008-06-22 22:10:05 -07:00
Abdulaziz Ghuloum 5a2501d4bb Added port-position and port-has-port-position? 2008-06-19 21:49:24 -07:00
Abdulaziz Ghuloum e65b39d95d All parameters that are bound to variables now have proper names.
E.g., pretty-width now prints as #<procedure pretty-width>.
2008-06-19 01:58:59 -07:00
Abdulaziz Ghuloum 4bb7e170b5 Some procedures (like console-output-port) did not get names when
printed (instead, they were just #<procedure>).  Names for
procedures that are defined like
  (define foo
    (let ([something ---]) 
      (lamdba () ---)))
now works.
2008-06-18 22:47:56 -07:00
Abdulaziz Ghuloum 1bd699349a Fixed a problem with port position accounting which was using fixnum

2008-06-17 21:05:01 -07:00
Abdulaziz Ghuloum 333dc03f8f (waitpid -1 #f) now returns #f if no child has died yet. 2008-06-13 22:11:51 -07:00
Abdulaziz Ghuloum 8f0f0abbca Applied a patch supplied by Derick Eddington that provides enhanced
functionality for waitpid (nonblocking waitpid and more status info)
as well as the ability to send a signal to a process, e.g., 
  (kill pid 'HUP).
2008-06-13 05:43:17 -07:00

Abdulaziz Ghuloum fe1f7077ff fixed minor bug in syntax-case where the wraps and marks of
top-marked wrapped syntax objects were incorrectly combined.
E.g., it used to be that:

  (syntax-case (datum->syntax #'foo #'(x y)) ()
    [(x y) 'shouldntmatch] [_ 'ok])

yields shouldntmatch; it's now ok.

  host name or connect".

documented yet and there is no error-checking mechanism for
verifying proper input.
2008-05-12 01:00:01 -04:00
Abdulaziz Ghuloum f8b0e949d9 - syntax-case now raises a syntax violation when _ appears in the

   1. &assertion
   2. &who: with-syntax
   3. &message: "pattern does not match value"

    1. &message: "invalid syntax"
    2. &syntax:

into the interaction environment.
2008-05-01 15:04:43 -04:00
Abdulaziz Ghuloum d49aed209a Added (interaction-environment). 2008-05-01 06:02:36 -04:00
Abdulaziz Ghuloum e7386cd7d7 Major changes to the interactive repl:
- We can now redefine imported identifiers.
- We can now use let-syntax, letrec-syntax, and modules at
  top-level.

Hand-wavey Repl Semantics:
- Imported identifiers mean what they meant previously.  In
  particular, you cannot set! imported identifiers.
- An imported identifier may be redefined using define.  Once
  something is defined at the top-level, a specific location for it
  is created, and all definitions, references, and set!s to that
  variable go through the top-level location.
- Re-importing an identifier shadows the top-level location.
- Redefining re-exposes the top-level location.
- and do on.
- A reference to an unbound variable also fabricates a top-level
  location for that variable.

Let's see how this goes.
2008-05-01 04:21:07 -04:00
Abdulaziz Ghuloum 1389f239fe Added process-nonblocking which is like process but returns
nonblocking ports.
2008-04-30 22:55:59 -04:00

    (with-output-to-port p (lambda () (printf "Hello\n")))
    (e))
"Hello\n"
2008-04-29 00:20:29 -04:00

Abdulaziz Ghuloum 89def78c3c Fixed the definition of identifier? and id? in expander so that only
top-make-wrapped (possibly annotated) symbols are identifiers.  It
used to be that symbols were considered identifiers by the previous
definition.
2008-04-28 14:01:49 -04:00
Abdulaziz Ghuloum 3ce6d037e4 Fixed a bug in module imports where some marks were missing in action.
(Note from Kent, extracted from chez scheme release notes, follows)

This always worked:

(let ()
  (define-syntax from
    (syntax-rules ()
      [(_ m v) (let () (import m) v)]))
  (module a (x) (define x 'x-of-a))
  (from a x))

Didn't work before this change:

(let ()
  (define-syntax x-from-a
    (syntax-rules ()
      [(_) (let () (import a) x)]))
  (module a (x) (define x 'x-of-a))
  (x-from-a))
2008-04-19 17:55:30 -04:00

2008-04-19 16:55:40 -04:00
Abdulaziz Ghuloum 177f6b84a7 Fixed a reader bug that causes '#!eof not to read properly.

Unhandled exception
 Condition components:
  1. &lexical
  2. &message: "invalid eof after quote read macro"
  3. &lexical-position:
      file-name: *stdin*
      character: 7

Now:
> '#!eof
#!eof

Abdulaziz Ghuloum bf6138f86f - Added reset-output-port! which sets the write index to 0 and
unregisters any callbacks associated with the buffer.
- commented out the call for unblocking the stdin for now
  (for reason yet unknown to me, it causes stdout to be unblocked
   as well, making writes to the console to come out in bizarre 
   mixed order)
2008-04-06 10:57:56 -04:00
Abdulaziz Ghuloum afd7592ae1 Added &i/o-read, &i/o-write, and &i/o conditions to read/write

Abdulaziz Ghuloum 2119f44125 Added a simple tcp server facility. See lab/greeting-server.ss. 2008-03-23 03:44:20 -04:00
Abdulaziz Ghuloum 9aaf306f16 Nonblocking sockets no longer raise a continuable exception when a
read or write operation would block.  Instead, they are schedules
with an event handler that `selects' on the pending file descriptors
and dispatches the appropriate callback.
2008-03-23 02:14:00 -04:00
Abdulaziz Ghuloum 6e599c4c72 refactored nonblocking code in ikarus-io.c and ikarus.io.ss 2008-03-23 00:41:49 -04:00
