Hello everyone!

I'm excited to share Hypershell, a modular, type-level DSL for writing shell-script-like programs directly in Rust! It's powered by Context-Generic Programming (CGP), which enables unprecedented modularity and extensibility, allowing you to easily extend or modify the language syntax and semantics.

I created Hypershell as a response to previous community feedback on CGP, seeking more practical application examples. Hypershell serves as a proof of concept, demonstrating how CGP can build highly modular DSLs — not just for shell-scripting, but also for areas like HTML or parsing. While it's an experimental project, shell-scripting was chosen as a fun and approachable example for all programmers. The blog post covers features like variable parameters, streaming I/O, native HTTP requests, and JSON encoding/decoding within your shell pipelines

A core innovation behind this is CGP's ability to bypass Rust's trait coherence restrictions, allowing for powerful dependency injection and eliminating tight coupling between implementations and concrete types. This means you can customize and extend Hypershell in ways that are typically very challenging in Rust.

Please feel free to share your thoughts and feedback on the project. I'm here to answer any questions!
