Project Status
This project is in its very early days, but a list of features that have been completed so far are as follows:
- Most of version 1 grammar defined grammar.bnf
- Extensive source error reporting system tracking.rs
- Lexical analyzer lexer/mod.rs
- Abstract Syntax Tree parser/ast.rs
Usage
Requirements
Because Zeta uses experimental feature flags (specifically only try_trait
currently), you will need to install nightly Rust.
You can install the specific recommended/tested nightly version with rustup toolchain install nightly-2019-07-31
, and set it to the default to be used by cargo with rustup default nightly-2019-07-31
Or, you can try the latest nightly Rust with rustup toolchain install nightly
, and set it to the default to be used by cargo with rustup default nightly
You will also need to install RLS for the specific nightly version you're using. If you're using VS Code, simply restart your editor after setting the default and it should prompt you to install RLS.
Install
Clone the repo by running
git clone https://github.com/zeta-lang/zeta
Build with the typical cargo
commands
Utilize
Note: Driver application is currently just a rudimentary testing app and does not yet support command line control
VS Code Integration
Visual Studio Code (Not to be confused with Visual Studio, they are totally separate products) is the recommended editor for developing Zeta. It is a fast and highly customizable text editor with some IDE-like features without the bulk, strict pipeline, or platform limitations of systems like Visual Studio. It is a free download and available for both platforms supported by Zeta
