## Project history and usage

cbfmt is a Rust command-line formatter driver for code blocks inside Markdown, Org, and reStructuredText documents.

### Project history

The official repository was created in July 2022. Its README defines cbfmt as a tool that iterates over document code blocks and runs configured formatting commands for each block language.

### Adoption history

The supplied package metadata shows cbfmt available through Homebrew and Nix. GitHub Releases published the v0.2.0 release on August 31, 2022.

### How it is used

A `.cbfmt.toml` file maps code block languages to formatter commands that read stdin and write stdout. Users can check or rewrite files, process directories recursively, or read a document from stdin.

### Why package nerds care

cbfmt is package-nerd-relevant because it composes existing language formatters instead of replacing them, giving documentation projects a small CLI for keeping embedded examples formatted.

### Timeline

- 2022: The official GitHub repository was created.
- 2022: v0.1.x and v0.2.0 releases were published.
- 2023: The official repository metadata records later maintenance activity.
