CLI Task Manager Argument Parser

Build a command-line argument parser for a task management tool that handles various input formats and types.

Requirements

Create a parser that accepts the following command-line arguments:

1. Task content flags:

   • --title: A string representing the task title (required for creating tasks)
   • --description or --desc: A string containing task description
   • --priority or -p: A number from 1-5 indicating task priority
   • --tags or -t: Can be specified multiple times to add multiple tags to a task

2. Operation flags:

   • --verbose or -v: Can be specified multiple times to increase verbosity level (0-3)
   • --list or -l: A boolean flag to list all tasks
   • --complete or -c: A boolean flag to mark tasks as complete
   • --help or -h: A boolean flag to show help information

3. Parsing behavior:

   • Unknown arguments should cause the parser to throw an error
   • Return a result object containing all parsed arguments
   • Collect any positional arguments (non-flag arguments) in the result

Test Cases

• When parsing ['--title', 'Buy groceries', '--priority', '2'], the result contains a title string and priority number @test
• When parsing ['-v', '-v', '-v'], the verbose flag value equals 3 @test
• When parsing ['--tags', 'work', '--tags', 'urgent', '-t', 'important'], the tags array contains three strings @test
• When parsing ['--desc', 'Task details'], the result contains the description under the canonical key name @test
• When parsing ['--unknown', 'value'], an error is thrown @test

API

/**

 * @returns {Object} Parsed arguments with positional args in the _ property
 * @throws {Error} When unknown arguments are encountered
 */
function parseTaskArgs(argv) {
  // Implementation here
