Science fiction space trading/smuggling simulation game using procedural generation.


Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Source code documentation for the project is available at: which is automatically built from master on every update.


To start developing or running the project you will need to install Rust stable, preferably using the Rustup tool

rustup install stable


Start by cloning the repository, then installing all the dependencies is as simple as running the following in the root directory:

cargo build

To run the project execute the following:

cargo run

Since the project uses quite a lot of compuations for generating a new galaxy you might want to run with optimizations on. To do that run:

cargo run --release

Furthermore, to see debug and info logs you need to run with the RUST_LOG environment variable:

bash/zsh: RUST_LOG=gemini=debug cargo run
fish: env RUST_LOG=gemini=debug cargo run

To build and install the executable on your system simply run:

cargo install

Running the tests

To run the automated tests, run:

cargo test

Note: No branch or pull request can be merged before all tests has passed in Travis.

And coding style tests

This project follows the Rust standard as specified by the Rustfmt project. Install Rustfmt by doing the following:

rustup component add rustfmt-preview --toolchain=nightly

To format the code run:

cargo +nightly fmt

Note: No branch or pull request can be merged before the style-guide has passed Rustfmt.
