Yoga-rs
=======
[![Build Status](https://travis-ci.org/bschwind/yoga-rs.svg?branch=master)](https://travis-ci.org/bschwind/yoga-rs)
A Rust wrapper for Facebook's Yoga layout library.
You may also want to check out [taffy](https://github.com/dioxuslabs/taffy) (a revived fork of the abandoned [stretch](https://github.com/vislyhq/stretch)) as it is a pure Rust implementation.
Dependencies
------------
- cargo
- rustc
- libc++-dev (LLVM’s libc++)
Build
-----
$ cargo build --release
Run Example
-----------
$ cargo run --release --example layout
Format Code
-----------
$ cargo +nightly fmt
Example Code
------------
```rust
#[macro_use]
extern crate yoga;
use yoga::prelude::*;
use yoga::Node;
use yoga::StyleUnit::{Auto, UndefinedValue};
fn main() {
let mut node = Node::new();
let mut child = Node::new();
let mut other_child = Node::new();
node.insert_child(&mut child, 0);
node.insert_child(&mut other_child, 1);
style!(node,
Margin(10 pt),
MarginLeft(Auto),
PaddingHorizontal(4 pt),
Left(16 %),
Bottom(UndefinedValue)
);
let child_styles = make_styles!(
Width(32 pt),
Height(32 pt),
FlexGrow(1.0),
Margin(Auto)
);
child.apply_styles(&child_styles);
other_child.apply_styles(&child_styles);
node.calculate_layout(512.0, 512.0, yoga::Direction::LTR);
println!("Layout is {:#?}", child.get_layout());
}
```
Testing
-------
The unit tests are automatically generated based on upstream fixtures and should not be edited manually.
```
$ cargo test
```
To generate the test cases:
Download the [ChromeDriver](http://chromedriver.chromium.org) binary and put it somewhere in your `$PATH`. Linux/MacOS example:
```
$ cp chromedriver /usr/local/bin
```
Then run the following
```bash
$ cd gentest
$ bundle install # Install the required ruby gems
$ ruby gentest/gentest.rb # Generate the tests
$ cargo +nightly fmt # Format the tests for consistency
```
