BasicIO
This object contains factories for scala.sys.process.ProcessIO,
which can be used to control the I/O of a scala.sys.process.Process
when a scala.sys.process.ProcessBuilder is started with the run
command.
It also contains some helper methods that can be used to in the creation of
ProcessIO.
It is used by other classes in the package in the implementation of various features, but can also be used by client code.

Concrete methods
Creates a ProcessIO from a function String => Unit.
Creates a ProcessIO from a function String => Unit. It can attach the
process input to stdin, and it will either send the error stream to
stderr, or to a ProcessLogger.
For example, the ProcessIO created below will print all normal output
while ignoring all error output. No input will be provided.
import scala.sys.process.BasicIO
val errToDevNull = BasicIO(false, println(_), None)- Value parameters:
- log
An optional
ProcessLoggerto which the output should be sent. IfNone, output will be sent to stderr.- output
A function that will be called with the process output.
- withIn
True if the process input should be attached to stdin.
- Returns:
A
ProcessIOwith the characteristics above.- Source:
- BasicIO.scala
Creates a ProcessIO that appends its output to an Appendable.
Creates a ProcessIO that appends its output to an Appendable. It can
attach the process input to stdin, and it will either send the error
stream to stderr, or to a ProcessLogger.
For example, the ProcessIO created by the function below will store the
normal output on the buffer provided, and print all error on stderr. The
input will be read from stdin.
import scala.sys.process.{BasicIO, ProcessLogger}
val printer = ProcessLogger(println(_))
def appendToBuffer(b: StringBuffer) = BasicIO(true, b, Some(printer))- Value parameters:
- buffer
An
Appendablewhich will receive the process normal output.- log
An optional
ProcessLoggerto which the output should be sent. IfNone, output will be sent to stderr.- withIn
True if the process input should be attached to stdin.
- Returns:
A
ProcessIOwith the characteristics above.- Source:

Creates a ProcessIO from a ProcessLogger .
Creates a ProcessIO from a ProcessLogger . It can attach the
process input to stdin.
- Value parameters:
- log
A
ProcessLoggerto receive all output, normal and error.- withIn

Returns a function InputStream => Unit given an optional
ProcessLogger.
Returns a function InputStream => Unit given an optional
ProcessLogger. If no logger is passed, the function will send the output
to stderr. This function can be used to create a
scala.sys.process.ProcessIO.
- Value parameters:
- log
An optional
ProcessLoggerto which the contents of theInputStreamwill be sent.
- Returns:
A function
InputStream => Unit(used by scala.sys.process.ProcessIO) which will send the data to either the providedProcessLoggeror, ifNone, to stderr.- Source:
- BasicIO.scala
Returns a function OutputStream => Unit that either reads the content
from stdin or does nothing but close the stream.
Returns a function OutputStream => Unit that either reads the content
from stdin or does nothing but close the stream. This function can be used by
scala.sys.process.ProcessIO.
- Source:
- BasicIO.scala
Returns a function InputStream => Unit that appends all data read to the
provided Appendable.
Returns a function InputStream => Unit that appends all data read to the
provided Appendable. This function can be used to create a
scala.sys.process.ProcessIO. The buffer will be appended line by line.
- Value parameters:
- buffer
An
Appendablesuch asStringBuilderorStringBuffer.
- Returns:
A function
InputStream => Unit(used by scala.sys.process.ProcessIO which will append all data read from the stream to the buffer.- Source:
- BasicIO.scala
Returns a function InputStream => Unit that will call the passed
function with all data read.
Returns a function InputStream => Unit that will call the passed
function with all data read. This function can be used to create a
scala.sys.process.ProcessIO. The processLine function will be called
with each line read, and Newline will be appended after each line.
- Value parameters:
- processLine
A function that will be called with all data read from the stream.
- Returns:
A function
InputStream => Unit(used by scala.sys.process.ProcessIO which will callprocessLinewith all data read from the stream.- Source:
- BasicIO.scala
Calls processLine with the result of readLine until the latter returns
null or the current thread is interrupted.

null or the current thread is interrupted.
