Crate whatlang

Whatlang is a Rust library to detect(regonize) natural languages. Apart from it, the library also recognizes scripts (writing system). Every language and script are represented by determined list of enums.

Examples

Using detect function:

use whatlang::{detect, Lang, Script};

let text = "Ĉu vi ne volas eklerni Esperanton? Bonvolu! Estas unu de la plej bonaj aferoj!";
let info = detect(text).unwrap();
assert_eq!(info.lang(), Lang::Epo);
assert_eq!(info.script(), Script::Latin);

// Confidence is in the range from 0 to 1.
assert_eq!(info.confidence(), 1.0);
assert!(info.is_reliable());

Using Detector with specified blacklist or whitelist:

use whatlang::{Detector, Lang};

let whitelist = vec![Lang::Eng, Lang::Rus];

// You can also create detector using with_blacklist function
let detector = Detector::with_whitelist(whitelist);
let lang = detector.detect_lang("There is no reason not to learn Esperanto.");
assert_eq!(lang, Some(Lang::Eng));

Structs

Detector	Configurable structure that holds detection options and provides functions to detect language and script.
Info	Represents a full outcome of language detection.
Options	Allows to customize behaviour of Detector.

Enums

Lang	Represents a language following ISO 639-3 standard.
Script	Represents a writing system (Latin, Cyrillic, Arabic, etc).

Functions

detect	Detect a language and a script by a given text.
detect_lang	Detect only a language by a given text.
detect_script	Detect only a script by a given text
