GDScript Verbal Expressions

A port of VerbalExpressions to GDScript. Tested on Godot 3.4.x.

Based on the Java implementation.

An itch.io demo can be found here.

See the tests directory for more examples.

Quickstart

1. Copy the addons/verbal-expressions/ folder to your project's addons directory (create the addons directory if it doesn't exist)
2. Load the verbal_expressions.gd file in your script and create a new instance of it
3. Start constructing the regex expression
4. Call build() to compile the expression
5. Use the usual built-in ReGex methods to do regex stuff

Example

Verify a URL

var verbal_expressions = load("res://addons/verbal-expressions/verbal_expressions.gd").new()

verbal_expressions \
    .start_of_line() \
    .then("http") \
    .maybe("s") \
    .then("://") \
    .maybe("www.") \
    .anything_but(" ") \
    .end_of_line() \
    .build()

var regex_match = verbal_expressions.search("https://godotengine.org/")

assert(regex_match != null)

# Technically unnecessary since `search(...)` returns null if there is no match
assert(regex_match.get_string() == "https://godotengine.org/")
