[!WARNING] Onoma and all of its editor integrations are still in early development. Expect bugs, breaking changes, and other general hiccups.

Onoma

ὄνομα — Onoma (pronounced OH-no-ma) is Greek for “name”, signifying not just a label, but the essence or character of a thing.

Onoma is a fast, language-agnostic semantic symbol indexer and fuzzy finder, which supports real-time cross-language symbol matching, without needing a full language server and without applying limits to workspace-wide queries.

It achieves this through incremental indexing with Tree-sitter and filesystem events, and includes typo-resistant fuzzy matching with a scoring system to prioritise relevant results.

While Onoma can be used as a standalone crate, its primary goal is to act as an editor-agnostic indexer and resolver which can be cross-compiled and integrated into text editors and IDEs.

Supported Languages

• Rust (.rs)
• Go (.go)
• Lua (.lua)
• Clojure (.clj)
• TypeScript (.ts and .tsx) / JavaScript (.js and .jsx)
• Python (.py)

Usage

1. Editor Integrations

Feel free to open an issue with ideas for additional editor integrations.

Currently, Onoma is integrated with:

1. Neovim, using onoma.nvim with Snacks Picker

2. Standalone Crate

[dependencies]
onoma = "0.0.7"

Documentation

Full documentation is available on docs.rs.

Contributing

Contributions are welcome!

The core Onoma backend should contain all editor-agnostic functionality, including improvements to indexing and fuzzy matching.

For editor-specific features or changes to bindings for a particular editor, please submit pull requests in the respective editor repositories listed above.

Testing

The tests can be run with:

cargo test
