Features

• Structural dynamic type system
• Type inference
• Sum types (via enums)
• Generic types and functions
• Pattern matching
• Syntax highlighting (via VS Code extension)

Roadmap

• Migrate to static type system
• Network I/O (Started)
• Filesystem I/O
• Error recovery
• Automatic function currying
• Function pipeline support?
• Async / await support
• Garbage collection
• Module and package systems
• String interpolation
• Full language support via LSP server.

Usage

Parse and interpret in the console any .nl file with the following command:

cargo run path/to/script.nl

Examples

Example scripts are provided in the examples/ directory.

Within that directory, sandbox.nl will be ignored by git.

Documentation

Documentation can be found on the Nala Wiki.

Editor Support

Syntax highlighting is available in the form of a VS Code extension here. Full environment agnostic language support in the form of an LSP language server is underway.

Known Issues

Comments are stripped before parsing in a preprocessing stage. This stage uses regex patterns to match both single-line (//) and multi-line (/* */) comments, which are imperfect. Embedding comment sequences inside strings (for example) will result in a portion of the string being stripped during preprocessing which in turn will cause a parse error.
