Révo Programming language

Revo is a dynamic programming language crafted with the pleasure of programming in mind. Its unique feature is that you must handle an error whenever you use a value, ensuring no crashes go unnoticed. This language offers powerful pattern matching tools like ?, orelse, and :unwrap() to simplify error handling.

Revo removes the need for explicit statements, allowing any expression to be executed at compile time. It enables scripts to be compiled into bytecode, with the flexibility to embed any value during the compilation process. The compiler and runtime environments are identical, facilitating seamless execution.

The language supports iterators over abstract syntax tree (AST) tokens, allowing you to transform them as needed before returning a new table of the modified AST. Atoms and tuples are highlighted as elegant solutions to various problems. Although the type system is optional, it is well-integrated and can significantly enhance code performance and correctness.

Most code in Revo is automatically inferred, often appearing as simple closures. Errors are propagated using the postfix operator '?', providing a straightforward error-handling experience. The latest version of Revo is available on GitHub, but due to the project's rapid evolution, it is recommended to build from the source code.

To get started with Revo, you'll need Zig version 0.16.0 for compilation. The project also suggests using the Anyzig version manager for easier management. Note that some features might not be available on Windows, so using Windows Subsystem for Linux (WSL) is recommended.

Once you have Revo set up, you can open the REPL (Read-Eval-Print Loop) by running the 'revo' command. To view documentation for a function like 'print', use the ':h' command followed by the function name. To quit the REPL, simply type ':q'. Finally, be aware that diagnostic tools such as highlighting and error messages can be integrated into your preferred editor, often bundled with Revo for native support.
