Abdulaziz Ghuloum 01c4afa320 Major work towards the AMD64 port. Most important of which is that
continuations work, more assembly instructions are testing in 64-bit
mode, and some arithmetic operations (shift-right, etc.) have been
fixed by removing some 32-bit dependencies.
2008-07-18 01:35:13 -07:00
Abdulaziz Ghuloum c3b12a22e8 the repl now resets on receiving &interrupted conditions. 2008-07-12 20:05:45 -07:00
Abdulaziz Ghuloum eccca7f4ea - Added trace-let-syntax, trace-letrec-syntax, as well as fixed
trace-define-syntax to handle variable transformers.

- added primops for fx comparison functions.
2008-07-11 22:31:40 -07:00
Abdulaziz Ghuloum 579b823f44 WIP on tag analysis, annotations, and utilization. 2008-07-06 23:48:16 -07:00
Abdulaziz Ghuloum d73dfd1287 - More work on the new optimizer
- Deleted old optimizer and changed the meaning of optimize level to
  be:
    0: bypass the optimizer
    1: copy propagation, constant folding, no inlining
    1: copy propagation, constant folding, with inlining
  The default is set to 1.
2008-06-29 12:35:34 -07:00
Abdulaziz Ghuloum 66464cc348 Fixed a bug when doing (/ 1 1 1 ...). 2008-06-28 13:02:05 -07:00
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 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

- changed implementation of string->number.
2008-05-31 20:10:17 -07:00
Abdulaziz Ghuloum 53905b9eea Changes from Derick Eddington supporting file system info:
- Added file-regular?, file-directory?, file-symbolic-link?,
  directory-list, make-directory, delete-directory, change-mode, 
  and make-symbolic-link.

- Bug fix in ikrt_open_input_fd and ikrt_open_output_fd which
  considered a 0 FD as an error.

- Bug fix in ikrt_getcwd about len+1.

- Bug fix of &i/o-file-protection which didn't have &i/o-filename as
  its parent.

- There is a new src/ikarus-errno.c file.  

- Made tcp-connect and friends tell when they "failed to resolve
  host name or connect".

- To support the uses of &i/o-filename subtypes, I modified
  print-condition so it will cleanly print the parents' fields of a
  condition;
2008-05-31 10:43:55 -07:00

2008-05-18 20:39:41 -07:00
Abdulaziz Ghuloum 4acf71d6d2 moved pretty-printing formats to their own library. 2008-05-12 00:35:19 -07:00
Abdulaziz Ghuloum f05f171f28 exported pretty-format, a parameter maker for setting the pretty
format for various forms.  The pretty format structure is not
documented yet and there is no error-checking mechanism for
verifying proper input.
2008-05-12 01:00:01 -04:00
Abdulaziz Ghuloum 5f92e4b96d Added current-directory parameter that gets/sets cwd. 2008-05-03 02:39:49 -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
Abdulaziz Ghuloum f69e82e6c5 Added with-output-to-port:

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

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 884f3fe921 Added tcp-server-socket-nonblocking, tcp-accept-connection-nonblocking

2008-03-23 05:02:12 -04:00

handle nonblocking sockets by continuous polling.
2007-12-27 22:17:54 -05:00
Abdulaziz Ghuloum 64dac92831 Added tcp-connect-nonblocking which is line tcp-connect but puts the
socket in nonblocking mode.  An operation that would block now
raises (continuable) a condition of type &i/o-would-block which
contains the port in question.  There's no way to handle the
condition gracefully yet.
2007-12-27 22:08:27 -05:00
Abdulaziz Ghuloum fc2d958419 Ikarus now recognizes ".sls", ".ss", and ".scm" extensions as well
as ".ikarus.sls", ".ikarus.ss", and ".ikarus.scm".
2007-12-27 15:16:08 -05:00
Abdulaziz Ghuloum 4f0a816295 Added a tcp-connect procedure that takes a host name and a service
name (e.g. "www.google.com" and "http") and returns two binary ports:
the first for output and the second for input.
Both ports must be closed for the connection to close.

Also added an example in lab/tcp-connect-example.ss which connects 
to an http server, sends "GET /\n" and prints the responde.
2007-12-26 17:35:58 -05:00

Abdulaziz Ghuloum 6eb6bf750d Added a (process "cmd" "args" ...) procedure that execs cmd, passing
args to it, and returns 4 values: 
* the process's pid
* the process's standard-input-port  (for writing)
* the process's standard-output-port (for reading)
* the process's standard-error-port  (for reading)
See lab/process-example.ss for a sample usage.

information when "time" or "time-it" are used.

for bootstrapping at least.
2007-12-10 07:28:03 -05:00

2007-12-05 05:01:56 -05:00
Abdulaziz Ghuloum e874d2d0a0 Added "include-into" macro.
(include-into ctxt "filename") included the contents of the file
  as if they were present in the context ctxt (which must be an
  identifier).  
  (include-into here "filename") would do the same thing as
  (include "filename")
2007-12-05 03:26:56 -05:00

Abdulaziz Ghuloum 5e7451167d Added close-port. Updated user's guide's list of unsupported
primitives.
2007-11-23 03:44:48 -05:00
