An entire regex scripting grammar, including DoPattern side-effects and parameterizable rules with parameters accessible by DoPatterns and CapturePatterns declared within, is compiled to 100% Java™ or C# code (rather than bytecode instructions of a specialized, embedded virtual machine), given a suitable change to the translator and additional helper classes in the library for primitive int and String data-type mappings. The regex scripting grammar realizes the advantages of hotspot compilation for the entire script, including side-effects. Side-effect pseudo-instructions generated by the automata are a stream of integers referenced to various DoPattern objects created by the script at regex composition time, rather than being a stream of instructions modeling the prelist and postlist statements of the DoPatterns written in the grammar.
