This little javascript libary helps you to write more readable regex code in javascript.
Just add the RegExpBuilder.js file from the js folder to your project.
##Compatibility This libary is compatible with everything which has ECMAScript5 implemented. The tests are using the promise feature of ECMAScript6.
##Examples
var builder = new RegExpBuilder();
builder.startLine().matchesFor("-+").zeroOrOneTimes()
.and().matchesDigit().zeroOrMoreTimes()
.and().matchesText(".").zeroOrOneTimes()
.and().matchesDigit().oneOrMoreTimes()
.beginGroup()
.matchesFor("eE")
.and().matchesFor("-+").zeroOrOneTimes()
.matchesDigit().oneOrMoreTimes()
.endGroup().oneOrMoreTimes().endLine();
var regExp = builder.build();The and() method is only optional so theoretical it could be omitting.
This is equivalent to:
var regExp = new RegExp("^[-+]?[0-9]*\\.?[0-9]+([eE][-+]?[0-9]+)?$");Or without using a string:
var regExp = /^[-+]?[0-9]*\.?[0-9]+([eE][-+]?[0-9]+)?$/;Get the first last name with a beginning 'A'.
Text: Lewis,Amelia;Winston,Oliver;Adams,Emily;Ashton,Thomas
var regExp = new RegExp("A[a-zA-Z]*,[a-zA-Z]+");Or with the builder:
var builder = new RegExpBuilder();
builder.matchesText("A").matchesFor("a-zA-Z").zeroOrMoreTimes().matchesText(",")
matchesFor("a-zA-Z").oneOrMoreTimes();
var regExp = builder.build();The tests are written for qUnit.
