Any C#/Typescript frameworks for language editors


Does someone know a framework for creating language editors in C#/Typescript? I need to create one at work.
I could also create an editor based on ANTLR but I am surely not the first guy with this problem.
“Intellisense”, Codecompletion, typechecks…

Are there any?

use microsoft vs code and tabnine for autocomplete and that is all.

I created ts-pegjs as a plugin on top of PEG.js. This gives you a PEG composable parser for your grammar in TypeScript.

We’ve used Microsoft Visual Studio Code with success. Extensions are written in TypeScript. A language server based on an ANTLR grammar can provide semantic checks, code completion, etc.
We may write an article about it in the future, actually.

Thanks. I do not know exactly about the complexity of VSCode. It sounds a bit overkill, but I also think it is a good direction.
My company uses a language to bind values from different data sources into template document. Think of “Dear {{UserProfile.DisplayName}}, …” at the beginning of a letter. The language is small. But if it develops good for the customer it becomes bigger.
I will search for VSCode examples. Any links for that are welcome.

This sounds a lot like a problem you could solve with Language Server Protocol - i know Microsoft is pretty big in supporting it in the past few years, so you might have success to look into specific example implementations from MS themselves.

seems that on the shelf solution is one path to explore

I had a little chat with my product owner. It should not appear like coding, it should be a point and click toolbox. Blockly or projectional editing in general comes into my mind.

If you are looking for a projectional editor, you can take a look at ProjectIt ( I give a demo next Thursday.


I hope I can find time for that meeting…

I suspect this answer may not be useful to you at this point, but I would recommend the FastColoredTextBox component in combination with an ANTLR parser if you want something free. If you want a paid component, AlterNET makes an editor component that supports C# out of the box and perhaps Typescript (I’m not sure). There is a licensing option for the source as well. I use The FastColoredTextBox control in my Grun.Net application for debugging C# ANTLR parser projects. It is a very solid free editor choice for embedding in projects.

Meanwhile I changed my job, they decided to use a point and click experience for the user.

But Langium is a good Typescript tool for creating languages with all the nice LSP features it helps to implement.
