Human2Regex

Regex dialect:

Your Regular Expression:

Human Speak:

// H2R supports // # and /**/ as comments
// A group is only captured if given a name. 
// You can use "and", "or", "not" to specify "[]" regex
// You can use "then" to combine match statements, however I find using multiple "match" statements easier to read

// exact matching means use a ^ and $ to signify the start and end of the string

using global and exact matching
