## Project history and usage

LanguageTool-Rust, also called LTRS, is both a Rust library and an `ltrs` command-line client for the LanguageTool HTTP API.

### Project history

The crate was created on crates.io on 2022-05-16 and developed as Rust bindings for the LanguageTool server API. Its README states that it can use the public LanguageTool API or a self-hosted LanguageTool server.

The changelog shows rapid early CLI and library work in May 2022, including commands such as `ping`, JSON output, and automatic use of the online LanguageTool server. Version 2.0.0, dated 2023-02-07, expanded the project structure and related-project documentation. Version 3.0.0, dated 2025-09-17, was a breaking refactor that separated library and CLI modules and added support for custom file types including Markdown, HTML, and Typst.

### Adoption history

LanguageTool-Rust sits in the Rust ecosystem as a typed client for a widely used proofreading server. Its adoption is niche but practical: developers can add grammar/style checking to Rust programs, while CLI users can query LanguageTool from scripts without writing API glue.

### How it is used

The README documents `cargo install languagetool-rust --features full` and an `ltrs` CLI with commands such as `ping`, `languages`, and `check`. By default, the CLI uses the public LanguageTool API, while users can point it at their own server.

### Why package nerds care

For package nerds, LTRS is a bridge package: it wraps a Java-origin proofreading service in Rust library types and a small CLI. It is useful in editor, documentation, CI, and prose-checking workflows where LanguageTool is wanted without running the Java client directly.

### Timeline

- 2022-05-16: Crate created on crates.io and early 0.0.x changelog entries began.
- 2023-02-07: Version 2.0.0 documented a broader project cleanup and related-project work.
- 2025-09-17: Version 3.0.0 introduced breaking CLI/library refactors and custom file-type support.
- 2025-12-31: Version 3.0.1 bumped the minimum supported Rust version and fixed raw output behavior.
