Dart package for command line applications to create an version display
Dart package for command line applications to create an version display.
Features
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:
- Use the
display()call to output the version data to stdout for display on the command line; - 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.
