Directly implementing Roslyn AST to JavaScript is quite complex. Converting Roslyn AST → ESTree AST → JavaScript might be a better approach. #1
Description
It’s great to see someone working on the same thing. My implementation is a bit different from yours, though. I convert Roslyn AST to Acornima ESTree AST, and then transform it into an ES6 module. I use IIncrementalGenerator + Target to compile and convert JS files. I’ve also written an analyzer to restrict the syntax that can be used. However, my code is still quite a mess. I’ll release it once I’ve tidied it up. Looking forward to progressing together.
Initially, I implemented a CSharpSyntaxWalker to handle AST conversion (not fully completed). Later research revealed that combining CSharpSyntaxWalker with OperationWalker could achieve more precise semantic matching.
