Are there any javascript frameworks for parsing/auto-completing a domain specific language?

I have a grammar for a domain specific language, and I need to create a javascript code editor for that language. Are there any tools that would allow me to generate a) a javascript incremental parser b) a javascript auto-complete / auto-suggest engine?

Thanks!

An Example of implementing content assist (auto-complete) using Chevrotain Javascript Parsing DSL:

https://github.com/SAP/chevrotain/tree/master/examples/parser/content_assist

Chevrotain was designed specifically to build parsers used (as part of) language services tools in Editors/IDEs. Some of the relevant features are:

  • Automatic Error Recovery / Fault tolerance because editors and IDEs need to be able to handle 'mostly valid' inputs.
  • Every Grammar rule may be used as the starting rule as an Editor/IDE may only want to implement incremental parsing for performance reasons.

You may want jison, a js parser generator. In terms of auto-complete / auto-suggest...most of the stuff out there I know if more based on word completion rather than code completion. But once you have a parser running I don't think that part is too difficult..
