regex-dsl

A Kotlin DSL for regular expressions

Provides a Groovy-style builder for regex

val r = regex {
    group("prefix") {
        literally("+")
        oneOrMore { digit(); letter() }
    }
    3 times { digit() }
    literally(";")
    matchGroup("prefix")
}

Currently supports:

• literally("text") that escapes the text
• anyChar(), digit(), letter(), alphaNumeric(), whitespace(), wordBoundary(), wordCharacter()
• startOfString(), endOfString()
• optional("text") and optional { /* inner regex */ },

oneOrMore("text") and oneOrMore { /* inner regex */ },

zeroOrMore("text") and zeroOrMore { /* inner regex */ }

• n times ("text") and n times { /* inner regex */ },

  n timesOrMore ("text") and n timesOrMore { /* inner regex */ },

  n timesOrLess ("text") and n timesOrLess { /* inner regex */ },

  n..m times ("text") and n..m times { /* inner regex */ }

• index = group { /* inner regex */ } and matchGroup(index),

  group("name") { /* inner regex */ } and matchGroup("name")

• anyOf('a', 'b', 'c'),

  anyOf('a'..'z', 'A'..'Z', '0'..'9'),

  anyOf("abc", "def", "xyz"),

  anyOf({ /* inner regex*/ }, { /* inner regex *? })

• include(anotherRegex)
