Need a Linter in this extension

[ChrisNiklasLucka]

Hi @Serhioromano,
to get nice and structured text, I need a linter in this extension. So in best case I want some text in the VS console, when naming of a variable is not right. Don't know if you can implement it? If you can do it I can put all linting-Tasks in a tabular here.

Best regards and stay safe
Chris

I can do that. That would be nice to have all those rules.

But that will take time. It is done through LSP with is not a trivial task. On the other hand, if I do it, it will auto indent, with [CTRL] go to definition, intellisence will suggest correct properties of struct and function blocks and so on. It will full blown ST editor even better that any currently existing one like CoDeSys 3.5.

Hi @Serhioromano thats great. Here you'll have a documents with requirements from my side - about 25 requirements (not all for linter I think).

@ChrisNiklasLucka this is very well written document. Thank you. Right now I am working on new Git Flow extension, but as soon as I finish it, I'll try to improve this one.

@Serhioromano thanks! Do you have any "timeline" for your programming goals? Do you think that this linter is ready in ~1 month or is it more a task about a half year? I ask, just du get an idea how long it whould take.
I have not that much knowledge in this programming language, but in other languages like python I have enought knowlegde, so if you can create a task line or something like this i could support you with my manpower.

Right now, half year sounds more realistic since I am doing it alone. You see the point with lint is not only lint. In order to implement it LSP has to be created with full code parse capability. Lint will be just a byproduct of that. I mean to have lint a full blown code parser have to be created.

@Serhioromano Probably you want to use ATNLR4 for this task. I understand that this will be a complete re-write of the code, but a parser/lexer will work much better than a REGEXP based parser. You define the grammar for ST and generate the parser/lexer with ANTLR4. Unfortunately it will be in Javascript and not TypeScript, so I don't know if this will work as part of the VSCode extension which is based on TypeScript.

Thank you. I was looking into this lib for quite a while already. Unfortunately I cannot find a guide how to do that. Docs I've found was not good enough. It is written as for someone who already understand parser and lexer just need to know how ATNLR works. I could not get a clear picture. Although I've created ATNLR file for ST.

I agree with you about the documentation. As far as I understood the process consists of a few step. First of all you have to define your grammar. Then you have to create the lexer/parser based on this grammar. Then you have to hook into the generated code (or vice versa) to work with the lexer/parser result.

I'll try to figure out how to work with this, too. I want to use it for a simple project of mine and also later on for a much more complex project.

You also need some kind of runtime. For JavaScript I suppose this is a good point to start.

Ш was successful at creating grammar and then generate lexer and parser. The thing I do not completely understand how to turn it into LSP.

Oh, I understand. For this I'm not able to help. I'm struggling with my own project because it's in C++ and the ANTLR4 runtime is not compiling at the moment. But maybe this repository might throw some light on the topic. As far as I understood it's a plugin for VSCode using the LSP and supports ANTLR parse trees.

Thank you for the link. That di not make anything clear as it is in C#. Although I used to code in C# decade ago and can read it partially, there are still lot of questions.

I also read this article

After which I fill like stupid. How come he explained everything and I still cannot make it.
