I'm looking for a parser generator that generates a C# parser for a relatively simple grammar. The generated parser should make it easy to implement IntelliSense-like code auto-completion based on the grammar.

In a nutshell I'm looking for pretty much something like Eclipse Xtext with two differences:

  1. It generates the parser as C# code.
  2. It allows me to add an IntelliSense-like code auto-completion feature easily to my end product (not to my IDE as Xtext* does), preferrably using a WPF-based approach.

What alternatives do I have based on these requirements?

What I found so far is only this (hopefully highly incomplete) list:

* I have used Xtext only to extend the Eclipse IDE so far - therefore I don't know if it also supports to easily put the auto-completion features into a non-Eclipse stand-alone application.

By the way: This is a re-post of a question that did not seem to fit on StackOverflow. On meta, it was suggested to me to give it a try here. And after reading the Help here this SE site seems to be the right place. Hopefully you'll agree with this assessment.

  • If you are willing to "implement your autocomplete", then any parser generator will do. If you are not willing to generate it, then what you are asking for isn't a parser generator, because it already understands there will be some kind of interactive component; parser generators don't. This is why Xtext contains a parser generator instead of being one. – Ira Baxter Mar 2 '16 at 16:59
  • Something like Jetbrains Nitra? It's in beta stadium and under heavy development. Worth a look. Can't recommend it, though, because I have too little experience – Thomas Weller Mar 2 '16 at 19:28
  • There is a library that makes it easy to write a grammar in C# that goes by the name "Irony - .NET Language Implementation Kit" currently hosted on the soon to be defunct CodePlex. Although there are few forks on github by third parties. – Theraot Apr 17 '17 at 19:52
