## Developing

The book is authored and published with [mdBook](https://rust-lang.github.io/mdBook/guide/installation.html). Follow the installation instructions to get the `mdBook` binary installed.

Run `mdBook serve` to boot up the web server that handles compiling everything.

When the code is pushed to the `main` branch on GitHub, an action runs that deploys it to the `gh-pages` branch.

## Key Versions

- DragonRuby Game Toolkit: v3.24, v4.0
- mdBook: v0.4.22

## Running Samples

The repository contains complete games for each separate code sample to ensure the code works and runs.

Code samples live in `src/code` and then are organized by chapter and then sections within a chapter.

Clone this book repository into a DragonRuby GTK engine directory and run the samples with:

``` console
./dragonruby book/src/code/chapter_03/01_input
```

## Publishing

How to make a release:

1. Merge the `main` branch into `offline`
2. Generate a new PDF via printing in Firefox, turning off the header and footer
3. Generate an HTML version of the book and zip it up
4. Create zips and upload them on itch.io
5. Create tags and releases for the offline branch and the main branch
