Feature Request: Add support for PLC ST (Structured Text) language

Validations

• I believe this is a way to improve. I'll try to join the Continue Discord for questions
• I'm not able to find an open issue that requests the same enhancement

Problem

Feature Request

I would like to request support for PLC ST (Structured Text) language in Continue.

What is PLC ST?

PLC ST (Structured Text) is a high-level programming language used in industrial automation and control systems, specifically for Programmable Logic Controllers (PLCs). It is one of the programming languages defined by IEC 61131-3 standard.

Why is this important?

1. ST is widely used in industrial automation
2. It's a text-based language that could benefit from AI assistance
3. Many automation engineers use ST daily for programming PLCs
4. Having Continue support would improve productivity for automation developers

Suggested features:

• Syntax highlighting for ST language
• Code completion
• Code analysis

Example ST code:

PROGRAM MainProgram
VAR
    Counter : INT := 0;
    Signal : BOOL;
END_VAR

IF Signal THEN
    Counter := Counter + 1;
    IF Counter >= 100 THEN
        Counter := 0;
    END_IF;
END_IF;
END_PROGRAM

Solution

@dipfocus I'd like to get a bit more detail and maybe clarify a few points.

Syntax highlighting for ST language

Are you referring to syntax highlighting in the chat window?

Code completion

This should work out of the box, Continue is more or less agnostic when it comes to language. We have a few optimizations for certain languages, mostly TypeScript and Python, but overall the completions depend more on the model you're using than on Continue itself.

Code analysis

Could you elaborate?
