linux standard input
Jan 21st, 2009, 8:10pm  
Hi All,

Is there a library for reading text data from Linux standard input / output?  
I am trying to get real-time input to Processing from a C program running on the same machine as Processing.  OS is Linux.

Thanks,
F

System.in is an InputStream, you can read it to get the info. You get the data with a pipe

Yes, I can use a pipe I think.  Are there examples of System.in used from pipes in Processing?

Mmm, if you use the Search on System.in, you will find a few examples but they look unsuccessful. Not sure it can work, because Processing is essentially a GUI program, these doesn't mix well with such input... I can be wrong, though, I haven't tried. You would need to export the sketch and pipe to the Java process running the jar, I think.

If you have control on what the C program does, it should be more reliable to use sockets, for example.
