Incremental output

[amoffat]

I pushed some code to PBS dev earlier today that allowed to do some really cool stuff like this:

from pbs import tail

# runs forever
for line in tail("-f", "/var/log/some_log_file.log", _for=True):
    print line

Or use callbacks:

from pbs import tail

def process_output(line):
    print line

p = tail("-f", "/var/log/some_log_file.log", _out=process_output)
p.wait()

As well as working with stdin dynamically for interactive programs.

I was wondering if there were any plans to support something similar in envoy? If so, I could probably brief you on some of the gotchas. Any plans for incremental output, ken?

Oh, looks like this is a duplicate of #8 from 5 months ago, my mistake :)
