Oniguruma-To-ES

This is a basic REPL for testing the output of Oniguruma-To-ES, an Oniguruma to JavaScript RegExp transpiler. See Oniguruma syntax for an overview, but there are many subtleties to Oniguruma's differences from JavaScript that aren't shown in the docs.

Try it

Flags: i m (JS flag s) x

The output shows the result of calling toRegExp. Oniguruma-To-ES includes functions to generate additional formats: compile, toOnigurumaAst, and toRegexAst (for an AST based on regex). You can run all of these from the console on this page.

More details

compile and toRegExp accept pattern: string, flags?: string, options?: object.
toOnigurumaAst and toRegexAst accept pattern: string, flags?: string.
You can pretty-print AST results by passing them to printAst in the console on this page.
