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 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:

// 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.

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. 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.

In your first commit message, please include the following statement:

I make this dedication for the benefit of the public at large and to the detriment of my heirs and successors.

This allows us to keep the library legally unencumbered, and free for everyone to use.
