process_run 0.10.12+2

Process run helpers for Linux/Win/Mac and which like feature for finding executables.

process_run

Process run helpers for Linux/Win/Mac.

Goals

Currently using Process.run does not stream output which is not convenient for lengthy operation. It requires using Process.start in a more complex way.

run and runCmd add verbose helper for that. Also dart binaries (pub, dart2js...) and any script can be called consistently on Mac/Windows/Linux

ProcessCmd allow creating command object that can be run and modified.

Usage

run

Additional options to Process.run are

• specifying stdin
• making it verbose

Additional feature

• It tries to resolve simple command like dart, firebase, flutter, or any script available on the user path on any Platform.

import 'package:process_run/process_run.dart';

Display dart version and the command executed:

await run('dart', ['--version'], verbose: true);

which

Like unix which, it searches for installed executables

import 'package:process_run/which.dart';

Find flutter and firebase executables:

var flutterExectutable = whichSync('flutter');
var firebaseExectutable = whichSync('firebase');

shell

Allows to run script from Mac/Windows/Linux in a portable way. Empty lines are added for lisibility

import 'package:process_run/shell.dart';

Run a simple script:

var shell = Shell();

await shell.run('''

# Display some text
echo Hello

# Display dart version
dart --version

# Display pub version
pub --version

''');

Flutter context

MacOS

If you want to run executable in a MacOS flutter context, you need to disable sandbox mode. See Removing sandboxing and ProcessException: Operation not permitted on macOS
