Progress class - dcli library

Constructors

Progress(LineAction stdout, {LineAction stderr = devNull, bool captureStdin = false, bool captureStderr = false}): Creates a Progress that allows you to individually control each aspect of how the Progress prints and captures output to stdout and stderr. It usually easier to use one of the pre-package Progress constructors such as Progress.print.
Progress.capture({bool captureStdout = true, bool captureStderr = true}): Captures the output of the called process to a list which can be obtained by calling Progress.lines once the process completes. By default both stdout and stderr are captured. Set captureStdout to false to suppress capturing of stdout. Set captureStderr to false to suppress capturing of stderr.
Progress.devNull(): Use this progress to have both stdout and stderr output suppressed.
Progress.print({bool capture = false}): Use this progress to print both stdout and stderr. If capture is true (defaults to false) the output to stdout and stderr is also captured and will be available in lines once the process completes.
Progress.printStdErr({bool capture = false}): Use this progress to only output data sent to stderr. If capture is true (defaults to false) the output to stderr is also captured and will be available in lines once the process completes.
Progress.printStdOut({bool capture = false}): Use this progress to only output data sent to stdout. If capture is true (defaults to false) the output to stdout is also captured and will be available in lines once the process completes.
Progress.stream({bool includeStdout = true, bool includeStderr = true}): EXPERIMENTAL

Properties

exitCode ↔ int?: The exist code of the completed process.
getter/setter pair
firstLine → String?: Returns the first line from the command or null if no lines where returned
no setter
hashCode → int: The hash code for this object.
no setterinherited
lines → List<String>: If the Progress was created with captureStdout = true or captureStderr = true then lines will contain the captured lines. If neither capture is true then lines will return an empty list.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
stream → Stream<String>: Returns a combined stream including stdout and stderr. You control whether stderr and/or stdout are inserted into the stream when you call stream(includeStderr: true, includeStdout)
no setter

Methods

addToStderr(String line) → void: adds the line to the stderr controller
addToStdout(String line) → void: adds the line to the stdout controller
close() → void: closes the progress.
forEach(LineAction stdout, {LineAction stderr = devNull}) → void
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onError(RunException error) → void: Sends or enqueues an error event.
toList({int skipLines = 0}) → List<String>: Returns stdout and stderr lines as a list.
toParagraph({int skipLines = 0}) → String: toParagraph runs the contents of this String as a CLI command and returns the lines written to stdout and stderr as a single String by join the lines with the platform specific line delimiter.
toString() → String: A string representation of this object.

Operators

operator ==(Object other) → bool: The equality operator.
