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.

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 Params
- log
An optional
ProcessLogger
to 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
ProcessIO
with the characteristics above.- Source

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 Params
- buffer
An
Appendable
which will receive the process normal output.- log
An optional
ProcessLogger
to 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 a ProcessIO
from a ProcessLogger
. It can attach the
process input to stdin.
- Value Params
- log

to receive all output, normal and error.- withIn
True if the process input should be attached to stdin.

Returns a function InputStream => Unit
given an optional
ProcessLogger

to stderr. This function can be used to create a
scala.sys.process.ProcessIO.
- Value Params

- Returns
A function
InputStream => Unit

or, ifNone
, to stderr.- Source

scala.sys.process.ProcessIO. The buffer will be appended line by line.
- Value Params
- buffer
