harper-core

harper-core is the fundamental engine behind Harper, the grammar checker for developers.

harper-core is available on crates.io. However, improving the API is not currently a high priority. Feel free to use harper-core in your projects. If you run into issues, create a pull request.

Example

Here's what a full end-to-end linting pipeline could look like using harper-core.

use harper_core::linting::{LintGroup, Linter};
use harper_core::parsers::PlainEnglish;
use harper_core::spell::FstDictionary;
use harper_core::{Dialect, Document};

let text = "This is an test.";
let parser = PlainEnglish;

let document = Document::new_curated(text, &parser);

let dict = FstDictionary::curated();
let mut linter = LintGroup::new_curated(dict, Dialect::American);

let lints = linter.lint(&document);

for lint in lints {
    println!("{:?}", lint);
}

Features

concurrent: Whether to use thread-safe primitives (Arc vs Rc). Disabled by default. It is not recommended unless you need thread-safely (i.e. you want to use something like tokio).
