Show HN: Shelgon: A Framework for Building Interactive REPL Shells in Rust I've been working on Shelgon, a framework that lets you build your own custom REPL shells and interactive CLI applications in Rust. You can use Shelgon to: - Create a custom shell with only a few lines of code - Build interactive debugging tools with persistent state between commands - Develop domain-specific language interpreters with shell-like interfaces - Add REPL capabilities to existing applications Getting started is straightforward - implement a single trait that handles your command execution logic, and Shelgon takes care of the terminal UI, input handling, and async runtime integration. For example, a simple echo shell takes less than 50 lines of code, including a full implementation of command history, cursor movement, and tab completion.
