## Project history and usage

snakefmt is the Snakemake code formatter, modeled culturally on opinionated formatters such as Black while targeting Snakefiles and Snakemake-specific syntax.

### Project history

The official GitHub repository was created in February 2020 and v0.1.0 was published in June 2020. The project metadata and README describe it as the uncompromising Snakemake code formatter.

### Adoption history

snakefmt is distributed through Homebrew and Nix in the supplied package metadata and supports pre-commit integration from its official README, making it easy to add to package and repository hygiene workflows.

### How it is used

Users run snakefmt against Snakefiles or directories. By default it searches parent directories for pyproject.toml and reads snakefmt and Black configuration from that file; command-line options override config values.

### Why package nerds care

snakefmt matters to package and workflow maintainers because it standardizes Snakemake formatting, can run in pre-commit, and reduces noisy diffs in scientific workflow repositories.

### Timeline

- 2020: Official GitHub repository created.
- 2020: v0.1.0 published on GitHub releases.
- 2026: Project metadata lists snakefmt 2.x and a Python 3.11+ requirement.
