Hi,
I'm wondering if someone would have ideas on how to read data in from stdin, or a /dev/ file or a fifo in pure-data. I've got another program producing data (basically a stream of numbers) and i'd like it to set variables in purdata (e.g. to set the freq. of the osc~). I've tried piperead~ but it seems to want to take .wav data instead.
Is there a way in pure-data to do this?
Thanks for any help - it is appreciated.

Send data from your data source via a socked using FUDI (look into the pure data src directory for *_pdsend.c) and use the [netreceive] object in pure-data. Or use MIDI.
Or load pyext and use files from there in a secondary thread. Or use modules "os" or "popen". (this means few lines of Python)
Or rewrite you program in Python. Or in PD. :)
There are also other ways.

There's also the pipeio~ object from the ext13 extensions: http://pd.klingt.org/files/ I looked at the source code; the pipewrite~ object actually writes a wav file to a pipe, but the piperead~ object reads data from a pipe without checking if it's a wav stream. So you might be in luck with piperead~.
Or you can use the shell object from the ggee extensions: ftp://xdv.org/pub/gige/ggext/ I think version 0.24 should work. -- Marc

Should be fairly easy to write a tcl program that sends the programs output line by line to PD via local socket.
