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.

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:
> (let-values ([(p e) (open-string-output-port)])
    (with-output-to-port p (lambda () (printf "Hello\n")))
    (e))
"Hello\n"
2008-04-29 00:20:29 -04:00
Abdulaziz Ghuloum d8cd4f0acf Added engine-handler parameter and a ($swap-engine-counter! <neg-fx>)
to (ikarus system $interrupts).
2008-04-29 00:10:49 -04:00

Abdulaziz Ghuloum 25344fa1d0 Added nanosleep as per bug 210678. 2008-04-11 05:36:54 -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)

Abdulaziz Ghuloum 1683997a12 fx* now detects overflow. 2008-02-12 14:46:18 -05:00
Abdulaziz Ghuloum 3811d0a4c2 Loops with a single free variable no longer allocate a closure. 2008-02-11 22:18:32 -05:00
Abdulaziz Ghuloum 4e5121af4e Implemented an experimental SCC letrec transformation which does not
work yet.
2008-02-10 03:27:31 -05:00

Abdulaziz Ghuloum eedbe65e44 Added bitwise-copy-bit. 2008-01-20 22:21:54 -05:00
Abdulaziz Ghuloum 4444496609 Fixes bug 181105: syntax pattern variable list length mismatch error
is obscure
2008-01-09 08:47:48 -05:00
Abdulaziz Ghuloum 341e53a36d 64-bit fasl files can now be produced and read. 2008-01-03 02:07:17 -05:00
Abdulaziz Ghuloum 4c3b17436f Added a tcp-connect-nonblocking-example.ss to demonstrate how to
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.

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.
