Historique du projet

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.

Historique d'adoption

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.

Modes d'utilisation

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.

Pourquoi les passionnés de paquets s'y intéressent

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.
