What is tabtab?

The tabtab npm package is designed to facilitate the creation of command-line tab completions for Node.js applications. It allows developers to easily add autocompletion features to their CLI tools, enhancing user experience by providing suggestions and completing commands as users type.

What are tabtab's main functionalities?

Basic Completion

This feature allows you to set up basic tab completion for a command. When the user types 'mycommand' and presses tab, it will suggest 'option1', 'option2', and 'option3'.

const tabtab = require('tabtab')();
tabtab.on('mycommand', (data, done) => {
  done(null, ['option1', 'option2', 'option3']);
});
tabtab.start();

Dynamic Completion

This feature allows for dynamic tab completion based on the user's input. The 'getSuggestionsBasedOnInput' function generates suggestions dynamically, providing a more interactive and context-aware completion experience.

const tabtab = require('tabtab')();
tabtab.on('mycommand', (data, done) => {
  const suggestions = getSuggestionsBasedOnInput(data.line);
  done(null, suggestions);
});
function getSuggestionsBasedOnInput(input) {
  // Logic to generate suggestions based on input
  return ['dynamic1', 'dynamic2'];
}
tabtab.start();

Subcommand Completion

This feature supports tab completion for subcommands. When the user types 'mycommand subcommand' and presses tab, it will suggest 'suboption1' and 'suboption2'.

const tabtab = require('tabtab')();
tabtab.on('mycommand', (data, done) => {
  if (data.prev === 'subcommand') {
    done(null, ['suboption1', 'suboption2']);
  } else {
    done(null, ['subcommand']);
  }
});
tabtab.start();
