Dart package for command line applications to create an version display.


The package displays a summary of version data for a command line application. The version data it provides includes:

  • the stated version number for your application;
  • the version of the operating system the application is being run on;
  • the number of CPUs available in the machine the application is being run on;
  • the system locale for the machine being run on;
  • the name of the local computer the application is being run on.

Different data is displayed to distiguish a AOT complied application from one runing as a Dart script. The displayed differences includes:

  • Last time the script was modified vs when the applcation was built (ie AOT compiled);
  • Version of Dart being used to execute the script vs Version of Dart the application was AOT complied with;

Simple usage provides two options for application version output:

  1. Use the display() call to output the version data to stdout for display on the command line;
  2. Use the asString() call to get a string copy of the version data – in case further manipluation is needed prior to output.

Easy to use, with no addtional external dependencies. Only uses the Dart SDK builtin module: dart:io.
