TSBunch: TypeScript Bundler (TS to TS)

TSBunch is a specialized TypeScript bundler designed to concatenate multiple `.ts` modules into a single `.ts` file without transpiling them to JavaScript. It is currently at version 0.4.25. Its primary use case is for platforms like CodinGame that require a single-file submission for TypeScript projects but do not allow or need JavaScript transpilation. Unlike mainstream bundlers (e.g., Webpack, Rollup, esbuild), TSBunch avoids generating JavaScript, instead leveraging TypeScript's `namespace` feature for module aggregation. This makes it unique for specific build workflows where the output must remain TypeScript. It has known limitations regarding full ES module import/export syntax support and does not resolve circular dependencies, operating primarily via string matching rather than a full AST analysis.
