@oclif/plugin-help

What is @oclif/plugin-help?

The @oclif/plugin-help package is designed to provide a help system for CLI (Command Line Interface) applications built with the oclif (Open CLI Framework). It allows developers to automatically generate and customize help output for their CLI commands.

What are @oclif/plugin-help's main functionalities?

Automatic help generation

This feature automatically generates help text for a specific command within an oclif CLI application. The help text includes the command's description, usage, arguments, flags, and examples.

const { Command, flags } = require('@oclif/command');
const Help = require('@oclif/plugin-help').default;

class MyCommand extends Command {
  async run() {
    // your command logic here
  }
}

MyCommand.description = 'Description of my command';

const help = new Help(this.config);
help.showHelp(['mycommand']);

Custom help classes

Developers can extend the default Help class to create custom help output. This allows for greater control over the formatting and content of the help text displayed to the user.

const { Command } = require('@oclif/command');
const { Help } = require('@oclif/plugin-help');

class MyHelpClass extends Help {
  // override methods to customize help output
}

class MyCommand extends Command {
  static helpClass = MyHelpClass;

  async run() {
    // your command logic here
  }
}

commander

Commander is another npm package for node.js designed to make it easy to write full-featured command line applications. It also automatically generates help information for commands. Commander is less opinionated than oclif and does not enforce a specific project structure.
