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

Creates aProcessIO from a functionString => Unit.
Creates aProcessIO from a functionString => Unit. It can attach the process input to stdin, and it will either send the error stream to stderr, or to aProcessLogger.
For example, theProcessIO created below will print all normal output while ignoring all error output. No input will be provided.
import scala.sys.process.BasicIOval 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.
Attributes
- Returns
A
ProcessIOwith the characteristics above.- Source

Creates aProcessIO that appends its output to anAppendable.
Creates aProcessIO that appends its output to anAppendable. It can attach the process input to stdin, and it will either send the error stream to stderr, or to aProcessLogger.
For example, theProcessIO 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.

Creates aProcessIO from aProcessLogger. It can attach the process input to stdin.
Value parameters

Closes aCloseable without throwing an exception
Copy contents of stdin to theOutputStream.
Returns a functionInputStream => Unit given an optionalProcessLogger.
Returns a functionInputStream => Unit given an optionalProcessLogger. If no logger is passed, the function will send the output to stderr. This function can be used to create ascala.sys.process.ProcessIO.
Value parameters
- log
An optional
ProcessLoggerto which the contents of theInputStreamwill be sent.
Attributes
- Returns
A function
InputStream => Unit(used byscala.sys.process.ProcessIO) which will send the data to either the providedProcessLoggeror, ifNone, to stderr.- Source
- BasicIO.scala
Returns a functionOutputStream => Unit that either reads the content from stdin or does nothing but close the stream.
Returns a functionOutputStream => Unit that either reads the content from stdin or does nothing but close the stream. This function can be used byscala.sys.process.ProcessIO.

Returns a functionInputStream => Unit that appends all data read to the providedAppendable.
Returns a functionInputStream => Unit that appends all data read to the providedAppendable. This function can be used to create ascala.sys.process.ProcessIO. The buffer will be appended line by line.
Value parameters
- buffer
An
Appendablesuch asStringBuilderorStringBuffer.
Attributes
- Returns
A function
InputStream => Unit(used byscala.sys.process.ProcessIO which will append all data read from the stream to the buffer.- Source
- BasicIO.scala
Returns a functionInputStream => Unit that will call the passed function with all data read.
Returns a functionInputStream => Unit that will call the passed function with all data read. This function can be used to create ascala.sys.process.ProcessIO. TheprocessLine function will be called with each line read, andNewline will be appended after each line.
Value parameters
- processLine
A function that will be called with all data read from the stream.
