string-search v1.2.0

string-search

Node module that carries out regex search on given multi-line string and returns match information.

Features

string-search finds and returns match information for each match.

• Accepts a multi-line string and regular expression in string format.
• Searches the given string with provided regular expression.
• Returns a promise that eventually resolves to an array. The array contains match objects each having following attributes -
  • line - line number(s) that the matched result was found on.
  • term - the search term.
  • text - the entire line(s) that the matched result was found in.

Usage

var stringSearcher = require('string-search');

stringSearcher.find('This is the string to search text in', 'string')
  .then(function(resultArr) {

  });

API

In lieu of a formal style guide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality.

Notes

Heavily inspired by lineder. I needed file reading part separated from text searching part so that a file can be read only once and multiple searches can be carried out on it. I also used promise to return results instead of a callback.
