javascript based code editor for custom language syntax

Question

I need javascript/html based code editor which I will customize for very simple custom coding language.

This editor tools needs to work in an offline solution so the source code must be downloadable or open. Language syntax will be look like very simplified java script even with out variables I will define just 'if then' and 'built in function name' for the custom language.

So it must have configuration support for custom coding language syntax

If you can refer some ready to use solutions, it will be so helpful
