## プロジェクトの歴史と使われ方

Topiary is a Rust code-formatting tool from Tweag that uses Tree-sitter grammars and query files to build formatters for multiple languages. Its project identity is a 'uniform formatter for simple languages' in the Tree-sitter ecosystem.

### プロジェクトの歴史

Topiary's changelog records an early prototype release in June 2022 and v0.1.0 in March 2023. Tweag announced the project publicly in March 2023 as a universal formatter engine aimed at both formatter authors and end users: authors write declarative formatting queries rather than a parser and engine, while users get consistent style from a single tool.

The Topiary Book explains the core architecture: Topiary relies on Tree-sitter parse trees and Tree-sitter query captures to decide where to add spacing, line breaks, and formatting actions. This makes the project part of the broader editor and parser ecosystem rather than a standalone formatter for only one language.

Through 2024 and 2025, releases added packaging, a CLI crate, dynamically fetched grammars, coverage and query tooling, OpenSCAD, WIT, SDML, Nickel and OCaml work, prefetching, man pages, and Tree-sitter upgrades. The changelog shows v0.7.3 at the end of 2025, while crates.io lists topiary-cli 0.7.3 as the current published CLI package in early 2026.

### 採用の歴史

Topiary is still a specialist formatter rather than a universal default, but it has package-manager reach in the input metadata through Homebrew, Nix, and Winget. Its audience overlaps with Nix/Tweag/Tree-sitter users, formatter authors, language-tooling maintainers, and developers working on languages that lack a mature dedicated formatter.

### 使われ方

Topiary is used either as a CLI formatter or as a framework for defining formatting behavior. Formatter authors provide Tree-sitter grammars and query files; users can run the CLI to format supported languages, prefetch grammars, check formatting in CI, and inspect coverage of formatting queries.

### パッケージ好きにとっての重要性

Topiary matters to package nerds because it turns formatting support into packageable language data: grammars, query files, and CLI releases can be distributed separately from language compilers. That fits ecosystems such as Nix, Homebrew, Winget, Tree-sitter, and editor tooling, where small language tools are composed from reusable packages.

### タイムライン

- 2022: v0.0.1 prototype recorded in the changelog.
- 2023: v0.1.0 released and Tweag announced Topiary.
- 2024: v0.5.1 era adds dynamic grammar handling and topiary-cli packaging appears on crates.io.
- 2025: v0.6.x and v0.7.x add language support, Topiary Book documentation, man pages, and Tree-sitter upgrades.
- 2026: crates.io lists topiary-cli 0.7.3 as the current published CLI release.
