About Pubspec Version Scanner

This little utility scans given directories and recursively finds any Dart pubspec.yaml files. Any files located are parsed for the name and version. The utility then generates a 'packages_g.dart' file that contains of map of the name/version found within each pubspec.

Usage

-h, --help                      Displays usage information.
-v, --version                   Displays version for this program.
-f, --from=<path,path, ...>     Path(s) with pubspec.yaml file.  Defaults to current directory.
-o, --out=<path>                Path to output the 'packages_g.dart' file.  Defaults to current directory.
-r, --[no-]recursive            Crawls subdirectories of any given paths and includes any pubspecs found.
                                (defaults to on)

Example

Given the following pubspec.yaml file that exists in the current directory:

name: pubspec_version_scanner
version: 1.0.0

Command:

dart pvs.dart --out lib

Will generate the following file in lib\packages_g.dart

// Generated code by Dart Package Version Builder

const packages = const <String, String> {
	"pubspec_version_scanner" : "1.0.0",
};

The file can then be imported into your own Dart project and referenced at runtime:

import "package:pubspec_version_scanner/packages_g.dart";

void main() {
    print("Version of this library is ${packages['package_ver']}");
}
