Re: I/O buffering.

2017-01-18 Thread Lindsay John Lawrence 
Hi Alex,

Thank you. That is a nice example.

The ability to explicitly flush buffered data on the output channel was
what I was looking for.
Of course, there is a existing function to do just that... that I should of
thought to look for... (flush)

I am still trying to get a handle on using  io channels in picolisp.. and
the nuances of '@'  :)

One way to do that has been to see where I can use channels to wire useful
functionality into existing projects.
For context, the Perl example I referenced is from here
https://httpd.apache.org/docs/2.2/rewrite/rewritemap.html#prg

Best regards,
/Lindsay.

Hi Lindsay,

I/O buffering can't be turned off, it happens on a lower (stdin) level.


I think what you mean is a low-level (e.g. character-wise) read as opposed to
the higher-level 'read' function.

This could be:

   (while (char)
  (prin
 (case @
("-" "_")
(T @) ) ) )

I/O buffering.

2017-01-17 Thread Lindsay John Lawrence 
Is is possible to turn off I/O buffering in a PicoLisp program?
e.g In Perl one can do something like this...

#!/usr/bin/perl
$| = 1; # Turn off I/O buffering
while () {
s/-/_/g; # Replace dashes with underscores
print $_;
}

I'd like to do something similar with a PicoLisp program.

Best Regards,
