The Regular-Expressions.info website has a new quick reference that lists all of the regex syntax in one single table along with a link to the tutorial section that explains the syntax. Use the quick reference if you’ve seen some syntax in somebody else’s regex and you have no idea what feature that syntax is for.

RegexBuddy 4 emulates regex flavors far more accurately and allows you to compare and convert regular expressions between any of the flavors it supports.

XRegExp is an open source JavaScript library. It extends JavaScript’s regex syntax and eliminates most cross-browser inconstencies and bugs. Last month’s update of the regexp.info website added full coverage of XRegExp to the tutorial and reference sections, but was missing the XRegExp page in the tools & languages section. This page has now been added.

The regular expressions reference tables on www.regular-expressions.info have been updated to show only two regex flavors at a time instead of all regex flavors discussed on the site. This makes the new reference tables just as easy to read as the tables from 10 years ago were.

RegexBuddy 4 was released earlier this month. Along with that, the Regular-Expressions.info website has been thoroughly updated with new content. In the coming weeks you can expect blog post that highlight the new topics on the Regular-Expressions.info website. Later on I’ll blog about more intricate regex-related issues that RegexBuddy 4 emulates but that the website doesn’t talk about or only mentions in passing.
