Description

Hey HN! I'm the author of SharpTS, a TypeScript interpreter and ahead-of-time compiler written in C#.*What makes it different:*- Dual execution modes - interpret TypeScript directly OR compile to native .NET executables - Full C# interop - compile TypeScript to DLLs that C# projects can reference with full type safety*What works today:*- Core TypeScript: classes, interfaces, generics, async/await, decorators - Advanced types: union/intersection types, literal types, type guards - Compiles to verifiable .NET IL with performance comparable to hand-written C# - 80+ unit tests, supports most of TypeScript's feature set*Why I built it:*I wanted to understand how TypeScript really works under the hood, and I thought .NET developers might appreciate being able to run TypeScript without Node.js. The AOT compilation to .NET IL was a fun challenge - mapping TypeScript's structural type system to .NET's nominal types required some creative solutions.*Current limitations:*- No npm module support (yet) - Some advanced type system features are still in progress - Standard library is partial (see STATUS.md)The repo has detailed architecture docs if you're curious about the implementation details. Would love feedback, especially from TypeScript or compiler folks!Example usage: ``` # Install dotnet tool install -g SharpTS# Interpret sharpts script.ts# Compile to .NET sharpts --compile script.ts dotnet script.dll ```Happy to answer questions!
