libtcod bindings for Rust

libtcod a.k.a. "The Doryen Library" is a smallish library designed for writing roguelikes. It provides a bunch of useful functionality such as:

• Text-based graphics API that doesn't suck as much as Curses or OpenGL
• Colours! (like, more than 16)
• Keyboard and mouse input
• Path finding
• Field of view
• Portable (works on linux, windows and mac)
• Lots of other stuff

This project provides Rust bindings for libtcod v1.6.3.

This project follows Semantic Versioning. Since we're under 1.0.0 anything goes. The API can change at any time.

Indeed, it probably should change! If you have better ideas on how it make it safer or more familiar to Rust developers, please let us know.

Documentation

We run rustdoc on every new commit:

http://tomassedovic.github.io/tcod-rs/tcod/index.html

But that's mostly useful for types, function signatures, etc. We don't have much in term of actual docs, but you can always check the official ones:

https://libtcod.readthedocs.io/en/stable/

Current status

All raw tcod bindings are available via the tcod-sys crate. In addition we want to provide safe (and more in line with the Rust style) wrappers -- if you can segfault outside of unsafe blocks, that's a bug. The safe bindings are not yet complete, however.

Already Implemented

• Colors
• Console
• Most of the System layer (FPS, time, fullscreen, screenshots)
• Field of view
• Map
• Path finding (both A* and Dijkstra)
• Pseudorandom number generator (prefer the rand crate, except for places where the API requires the built-in generators)
• Name generator
• Image toolkit
• Line toolkit
• Noise
• BSP toolkit

Probably Won't Ever Be Implemented Because Rust Provides This Already

• Filesystem utilities
• Containers
• Compression toolkit (there will probably be a better Rust library for this)

Not Implemented Yet But Should Happen At Some Point In The Future

• Everything else!

How to use this

tcod-rs depends on libtcod so you need to build or download the official version. The libtcod version known to work is bundled with tcod-sys and Cargo will build it for you, but you need the build dependencies installed.

Alternatively, you can provide the precompiled libtcod library to override the building process. See below.

To use tcod-rs, add this to your game's Cargo.toml:

[dependencies]
tcod = "0.15"

Building on Linux

Run the equivalent of:

$ sudo apt-get install gcc g++ make libsdl2-dev
$ cd yourgame
$ cargo build --release
$ cargo run --release

on your distro.

Building a dynamic library

By default, tcod-rs will build the library statically on Linux as including the code into the executable is usually more convenient. To build a dynamic library specify the dynlib feature for tcod-sys in Cargo.toml

[dependencies.tcod-sys]
version = "*"
features = ["dynlib"]

Building on Windows (with MSVC)

Make sure you have Visual Studio 2013 or later with the C++ tools option installed. You also need the "MSVC ABI" version of the Rust compiler (as opposed to the "GNU ABI" one).

Then, set up the compilation environment, make sure Rust is in your PATH and run Cargo:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat amd64
set PATH=%PATH%;C:\Program Files (x86)\Rust\bin
cd yourgame
cargo build --release
cargo run --release

Building on Windows (with MinGW)

You have to download and install MinGW. Then, add Rust's and MinGW's bin directories to your path and compile your game:

set PATH=%PATH%;C:\Program Files (x86)\Rust\bin;C:\MinGW\bin
cd yourgame
cargo build --release
cargo run --release

Building on Mac OS X

1. Install Homebrew
2. Run:

$ brew install pkg-config sdl2
$ cd yourgame
$ cargo build --release
$ cargo run --release

This is based on the instructions from Jared McFarland's roguelike tutorial.

To test this, you can clone this repository directly and run the one of the provided examples:

$ git clone https://github.com/tomassedovic/tcod-rs.git
$ cd tcod-rs
$ cargo run --example keyboard

Using existing binary distribution

If you don't want to build libtcod yourself, you can instruct Cargo to override the build script. See .cargo/config from the repository for an example.

NOTE: The official MinGW pre-built libraries (for Windows) don't seem to work with tcod-rs. We're not sure exactly why this is so we'd appreciate anyone's help!

Contributing

The raw bindings were generated using rust-bindgen and are located at src/ffi.rs. The safe (hopefully?) wrapper was built on top of them at src/lib.rs.

This is far from done, patches to missing functionality wrappers, documentation and examples are very much appreciated. If your patch (any patch -- including typos) gets accepted, you'll get a commit access if you want it.

We accept GitHub as well as regular pull requests (i.e. emailing or tweeting the URL of your feature branch works).

You can regenerate the raw bindings by running:

bindgen -builtins -l tcod include/libtcod.h -o src/ffi.rs
