ProcessLogger

scala.sys.process.ProcessLogger

Encapsulates the output and error streams of a running process. This is used by scala.sys.process.ProcessBuilder when starting a process, as an alternative to scala.sys.process.ProcessIO, which can be more difficult to use. Note that a ProcessLogger will be used to create a ProcessIO anyway. The object BasicIO has some functions to do that.

Here is an example that counts the number of lines in the normal and error output of a process:

import scala.sys.process._

var normalLines = 0
var errorLines = 0
val countLogger = ProcessLogger(line => normalLines += 1,
                               line => errorLines += 1)
"find /etc" ! countLogger

If a process is begun with one of these ProcessBuilder methods:

def !(log: ProcessLogger): Int
def !<(log: ProcessLogger): Int

The run will be wrapped in a call to buffer. This gives the logger an opportunity to set up and tear down buffering. At present the library implementations of ProcessLogger simply execute the body unbuffered.
