About

The main use case for the lib is to be able to take valid path values out of verbose outputs such as those generated by a git status command:

• modified: src/Router.js resolves to src/Router.js
• ?? src/utils/__tests__/file.test.js resolves to src/utils/__tests__/file.test.js

This library was primarily put together for usage in iPipeTo which allows for its users to easily extract a path out of a random input value. Some extra effort was made to ensure extract-path works well as a separated lib in the hope that it can be useful for different use cases out there. Feel free to refer to iPipeTo source code as a implementation example if ever needed.

Install

npm install extract-path

Usage

// example.js
const extractPath = require('extract-path');

extractPath('Selected file: ~/Documents/foo.js ...')
	.then(path => {
		console.log(path);
		// ~/Documents/foo.js
	});

API

The API only exposes a single function, that receives a string and returns a Promise which resolves with a single, valid string value or undefined if there was no possible match.

extractPath(str, opts)

• str string value to be parsed in order to extract a valid fs path
• opts [optional] object containing the following:
  • validateFileExists boolean wether the module should validate the file exists, defaults to true
  • resolveWithFallback boolean uses a fallback system that matches the entire input if a path couldn't be infered from the input, defaults to true

Credit

extract-path is heavily inspired by the work done in PathPicker parsing algorithm and regular expressions.
