JavaScript implementation ofSimple Regex 🎉🎉🎉

Because of the JavaScript regex engine, there is something different fromSimple Regex

• NOT supportas to assign capture name.
• NOT supportif already had/if not already had
• NOfirst match and NOall lazy, since in JavaScriptlazy means non-greedy (matching the fewest possible characters).

npm install srl

Class SRL accepts a Simple Regex Language string as input, and return the builder for the query.

The builder can agenttest/exec method to the generated regex object. Or you can useget() to take the generated regex object.

constSRL=require('srl')constquery=newSRL('letter exactly 3 times')query.isMatching('aaa')// truequery.getMatch('aaa')// [ 'aaa', index: 0, input: 'aaa' ]query.digit().neverOrMore().mustEnd().get()// /[a-z]{3}[0-9]*$/g

Required Node 6.0+ for the ES6 support, Or you can useBabel to support Node below 6.0.

UsingWebpack andbabel-loader to pack it if want to use in browsers.

In SRL-JavaScript we applyg flag as default to follow theSimple Regex "standard", so we provide more API to use regex conveniently.

• isMatching - Validate if the expression matches the given string.
• getMatch - Get first match of the given string, like runregex.exec once.
• getMatches - Get all matches of the given string, like a loop to runregex.exec.
• removeModifier - Remove specific flag.

First, clone repo and init submodule for test.

SRL-JavaScript depends onMocha andIstanbul to test code. You can use them like this:

npm installnpmtest# testnpm run coverage# Get coverage locally
