Install: pip install nlprule

Use:

from nlprule import Tokenizer, Rules

tokenizer = Tokenizer.load("en")
rules = Rules.load("en", tokenizer)

rules.correct("He wants that you send him an email.")
# returns: 'He wants you to send him an email.'

rules.correct("I can due his homework.")
# returns: 'I can do his homework.'

for s in rules.suggest("She was not been here since Monday."):
    print(s.start, s.end, s.replacements, s.source, s.message)
# prints:
# 4 16 ['was not', 'has not been'] WAS_BEEN.1 Did you mean was not or has not been?

for sentence in tokenizer.pipe("A brief example is shown."):
    for token in sentence:
        print(
            repr(token.text).ljust(10),
            repr(token.span).ljust(10),
            repr(token.tags).ljust(24),
            repr(token.lemmas).ljust(24),
            repr(token.chunks).ljust(24),
        )
# prints:

Recommended setup:

Cargo.toml

[dependencies]
nlprule = "<version>"

[build-dependencies]
nlprule-build = "<version>" # must be the same as the nlprule version!

build.rs

fn main() {
    println!("cargo:rerun-if-changed=build.rs");

    nlprule_build::BinaryBuilder::new(
        &["en"],
        std::env::var("OUT_DIR").expect("OUT_DIR is set when build.rs is running"),
    )
    .build()
    .validate();
}

src/main.rs

use nlprule::{Rules, Tokenizer, tokenizer_filename, rules_filename};

fn main() {
    let mut tokenizer_bytes: &'static [u8] = include_bytes!(concat!(
        env!("OUT_DIR"),
        "/",
        tokenizer_filename!("en")
    ));
    let mut rules_bytes: &'static [u8] = include_bytes!(concat!(
        env!("OUT_DIR"),
        "/",
        rules_filename!("en")
    ));

    let tokenizer = Tokenizer::from_reader(&mut tokenizer_bytes).expect("tokenizer binary is valid");
    let rules = Rules::from_reader(&mut rules_bytes).expect("rules binary is valid");

    assert_eq!(
        rules.correct("She was not been here since Monday.", &tokenizer),
        String::from("She was not here since Monday.")
    );
}

nlprule and nlprule-build versions are kept in sync.
