ExecFinder

ExecFinder is a Node.js module that helps you find executable files (executables) on different platforms such as Windows, macOS, and Linux. It provides a way to scan through common directories where executables are often installed, making it easier to locate specific executable files.

Installation

You can install the ExecFinder module using npm:

npm install exec-finder

Usage

const ExecFinder = require('exec-finder');

const finder = new ExecFinder();

// Find executables by name and return an array of file paths
finder.find('vlc')
  .then(files => {
    console.log('Found VLC executables:');
    console.log(files);
  })
  .catch(error => {
    console.error('Error:', error);
  });

API

new ExecFinder([options])

Creates a new instance of ExecFinder. You can provide optional configuration options:

• options.recursion: The maximum recursion level when scanning subdirectories (default: 2).

finder.scanDirs([refresh])

Scans the common directories for executables. Returns a promise that resolves to an array of file paths.

• refresh (optional): Set to true to force a refresh of the executable list.

finder.find(names, [options])

Finds executables by name. Returns a promise that resolves to an object containing arrays of file paths for each name.

• names: A string or an array of strings representing executable names.
• options.refresh (optional): Set to true to force a refresh of the executable list.
• options.first (optional): Set to true to return only the first found executable path.

finder.findOne(names)

Finds the first occurrence of an executable by name. Returns a promise that resolves to the first found executable path.

Platform Support

• Windows: Supports scanning in common Program Files directories and User AppData directories.
• macOS: Supports scanning in common Application directories, /usr/bin, /usr/local/bin, /opt, and user's bin directory.
• Linux: Supports scanning in /usr/bin, /usr/local/bin, and /opt.
