Overview

Vim regular expressions are powerful, but they pre-date Perl.

This can be frustrating since the Perl-flavored-regex syntax has expanded beyond into other programming languages and contexts, becoming a de-facto standard.

This guide is a quick cheatsheet and tipsheet for using regular expressions in Vim for those who may be more familiar with Perl.

Quick examples for vimmers who like Perl regex
