[chuck-users] ChucK and STDIN

[Ge Wang]

Greetings!

stdin (and file i/o in general) is on the way.

Right now, there are a few hacked/experimental objects we've use 
internally:

The Skot object: a event-based stdin reader
The PRC object: string tokenizer

They are not in the standard build - you'd have to enable them by adding a 
compiler flag: -DAJAY.  Which platform are you using?  We can post an 
executable with these compiled in, if you like.

They will allow one to write code like:

     Skot skot;

     // infinite event loop
     while( true )
     {
         // prompt and wait
         skot.prompt("enter data:") => now;
         // get the results
         while( skot.more() )
         {
             <<< skot.getLine() >>>;
         }
     }

and you can use PRC to tokenize the text.

The actual stdin and file I/O is definitely on the way (thanks to Martin 
Robinson), we just haven't integrated/fully tested it yet.

The KBHit class is implemented in C/C++, in ulib_std.cpp.

You probably already found these:
