I second Jonathan’s suggestion of RichTextFX. To do syntax highlighting and style the text area you can use a combination of CSS and an extension I wrote for RichTextFX that allows you to highlight any language’s syntax based on an ANTLR grammar. It allows you to pass a mapping between an ANTLR token type and class name to do the highlighting. The work is still in it’s infancy, but it works and might be helpful to you. You can see it at https://github.com/jrguenther/Xanthic. You should be able to create a stylesheet the is similar to monokai.
The goal of Xanthic is to create a tool like pygments written in Java and making use of the ANTLR lexer/parser library. One of the output formats will be RichTextFX StyleSpans. One of the other goals of the project is to make use of the large ecosystem of pygments stylesheets by providing a converter to make them JavaFX stylesheets. Just haven’t got to it yet.
