## Project history and usage

Chadwick is a suite of command-line tools for extracting and transforming baseball play-by-play and boxscore data in the DiamondWare format used by Retrosheet. Its significance is concentrated in the baseball data community rather than general-purpose CLI culture.

### Project history

The official documentation says Chadwick is written and maintained by Dr. T. L. Turocy at the Chadwick Baseball Bureau and is copyrighted 2002-2023. The project provides tools such as cwevent, cwgame, cwbox, cwdaily, cwsub, and cwcomment, with several utilities replacing or extending earlier DiamondWare programs.

### Adoption history

Chadwick's adoption follows the Retrosheet and baseball research ecosystem: the documentation is meant to be read alongside Retrosheet materials, and acknowledgments cite support or guidance from Sports Reference, the Society for American Baseball Research, XMLTeam, and Retrosheet. The supplied input records Homebrew packaging, while the official README notes that Chadwick may also be available in package managers and provides Windows binaries through GitHub releases.

### How it is used

Users run Chadwick tools to turn Retrosheet play-by-play event files and box scores into delimited output, field lists, game-level summaries, substitution data, comments, and daily statistical totals. It is a data-cleaning and extraction toolchain for people who want reproducible command-line access to historical baseball game data.

### Why package nerds care

For package maintainers and data-tool collectors, Chadwick is a useful example of a domain-specific C command-line suite that packages well: stable executables, no credentials or service dependency, ReadTheDocs documentation, source releases, and value to a narrow but serious research community.

### Timeline

- 2002: Official documentation dates the Chadwick copyright period from 2002.
- 2023: Official documentation records maintenance and copyright through 2023.
- Release metadata: The README identifies 0.10.0 as the documented release and directs users to GitHub releases.

### Related projects

- Chadwick is tightly related to Retrosheet and the DiamondWare utilities BEVENT, BGAME, and BOX, which its tools replace or extend. It also sits near Sports Reference and SABR workflows because those communities depend on structured historical baseball data.
