**DEPRECATED in favor of [whatlang][],** which is native Rust and
smaller. If you have a compelling use-case for this code, please open an
issue. Simple PRs, especially for bug fixes, will still be read and
possibly merged.

This Rust library detects the language of a string using the
[cld2 library][cld2] from the Chromium project.
To use it, add the following lines to your `Cargo.toml` file and run `cargo
update`:
```
[dependencies.cld2]
git = "git://github.com/emk/rust-cld2"
```
Then you can invoke it as follows:
``` rust
// Put these two lines the top of the file.
extern crate cld2;
use cld2::{detect_language, Format, Reliable, Lang};
let text = "It is an ancient Mariner,
And he stoppeth one of three.
'By thy long grey beard and glittering eye,
Now wherefore stopp'st thou me?";
assert_eq!((Some(Lang("en")), Reliable),
detect_language(text, Format::Text));
```
You can also pass in language detection hints and request more detailed
output. For details, please see [the API documentation][apidoc].
### Contributing
As always, pull requests are welcome! Please keep any patches as simple as
possible and include unit tests; that makes it much easier for me to merge
them.
If you want to get the C/C++ code building on another platform, please see
`cld2-sys/build.rb` and [this build script guide][build-script]. You'll
probably need to adjust some compiler options. Please don't hesitate to
ask questions; I'd love for this library to be cross platform.
