JavaScript implementation of Simple Regex 🎉🎉🎉
Because of the JavaScript regex engine, there is something different from Simple Regex
- NOT support
asto assign capture name. - NOT support
if already had/if not already had - NO
first matchand NOall lazy, since in JavaScriptlazymeans 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 agent test/exec method to the generated regex object. Or you can use get() to take the generated regex object.
const SRL = require('srl') const query = new SRL('letter exactly 3 times') query.isMatching('aaa') // true query.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 use Babel to support Node below 6.0.
Using Webpack and babel-loader to pack it if want to use in browsers.
In SRL-JavaScript we apply g flag as default to follow the Simple 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.execonce.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 on Mocha and Istanbul to test code. You can use them like this:
npm install npm test # test npm run coverage # Get coverage locally
