macschema

 Toolchain for generating JSON definitions of Apple APIs.

You can download from releases or use Homebrew:

$ brew install progrium/taps/macschema

Chrome is required for downloading topic data. You can also use headless Chrome in Docker. We recommend chromedp/headless-shell.

Using macschema

The macschema tool has several subcommands for downloading topics from Apple documentation and parsing topics into schemas. The commands will assume they can use two directories in the working directory: api and doc, where schemas and topics are downloaded and saved as JSON.

To pull and show a schema, which will download relevant topics and parse into schema:

$ macschema pull appkit/nswindow --show

Other commands:

$ macschema
