Re: [chuck-users] input | chuck <read_stdin_and_do_stuff>

Hi v4hn, I had a similar issue, stdin/stdout doesn't really work well in ChucK. However, I gave OSC (http://en.wikipedia.org/wiki/Open_Sound_Control) a try for ChucK/Python communication. This works really good. Check out pyOSC (https://trac.v2.nl/wiki/pyOSC) for the Python part and the OSC examples in the ChucK examples folder.

So thanks for providing this interpreter! Well, right now she's coding a automatic composition tool(in python), which generates some (midi) numbers and prints them on the screen. Since this will be an any-time algorithm, the (actually quite simple) task for the audible back-end - which (she insists) should be written in ChucK - is to read the numbers from standard input and generate matching sounds. So the use-case would look like this:

./compose | chuck play_composition.ck

RTFM and RTFS got me to ConsoleInput and FileIO with the second not being able to connect to stdin. At the moment the only - quite hacked - way (AFAICS) to read /anything/ from stdin looks like this: <<< ConsoleInput in; while(true){ in.prompt(); line= in.getLine(); ... }

...

...

This doesn't realize EOFs, but keeps waiting, does it? And since FileIO provides a readInt() function, it would be nice to use it in this case... Is there a way, to read from stdin through some IO-Interface of ChucK or anything else 'official' - aka not stating in the source that it's just something hacked? If not, are there any ideas on implementing this in Version 1.2.1.4 ? Well, that's for now, regards, v4hn
