Excalibur.js Site & Docs

Build Status

Contributing

Running the Site

# Install dependencies
npm install

# Initialize sub repos
git submodule init
git submodule update

# Run site for docs or development
npm run develop

GH_TOKEN GitHub Personal Access Token

You will need a GH_TOKEN environment variable for the site to start. The scope can be repo:public. See Creating a personal access token in GitHub documentation for details.

You can specify the token in your system environment variables on Windows or Linux.

Writing Docs

User documentation can be contributed to in the /docs folder in this repository! It's written in Markdown and follows a very simple format:

xx-cool-docs.md

title: "My Cool Documentation Page Title"
url: /cool-docs

---

Just some neat docs that are super awesome and helpful, this is just Markdown-formatted.

A relative-path image embed:

![screenshot](xx-cool-docs/cool-screenshot.png)

The xx in the filename helps determine the sort order of the navigation (until we come up with a better structure).

Everything else is taken care of--table of contents, image generation, code embedding, etc.

Linking to Images

To embed an image, we recommend creating a corresponding folder next to your documentation file named the same and put images there. Then you can reference them like:

![screenshot](xx-cool-docs/cool-screenshot.png)

This is just a relative path to your image, as simple as that!

Adding Notes

You can embed a "note" block element like:

<Note> An info variant note </Note>
<Note variant="warning"> A warning variant note </Note>
<Note variant="error"> A error variant note </Note>
<Note variant="success"> A success variant note </Note>

Note: The blank line after <Note> is important to format the body as Markdown. Prettier will handle this for you, if you forget.

Embedding Examples

To embed an iframe pointing to our Storybook-based examples, use the <Example /> component:

<Example story="id_of_story" />

The story prop takes the Storybook ID to navigate to.

TODO: Allow embedding just the canvas.

Build Environment

Requirements

  • Node.js (16.x)
  • GH_TOKEN defined with your GitHub Personal Access Token that has access to excaliburjs org

Packages we use

  • Gatsby for static site generation
  • gh-pages for deployment
  • Semantic UI framework

Once you've cloned the repository, run the following commands:

# Install dependencies
npm install

# Run site for local development
npm run develop

# Watch for style changes (css)
npm run styles

# Compile API reference documentation for each Excalibur tag
npm run docs

We recommend using the free Visual Studio Code editor since it's easy to use and works on any platform.

Building styles

For building Semantic UI:

  • Ruby 2.2.x (ensure it's in PATH)

  • Ruby Gems 2.6.x (fix SSL error on Windows x64)

  • Sass (gem install sass)

  • Windows or Unix-like

    Build styles (outputs css)

    npm run build:styles

    Watch for style changes

    npm run styles

During local development, you'd open two terminals with npm start and npm run styles at the same time. The CI build will ensure any unbuilt styles are built and deployed so you don't have to remember to compile CSS before commit.

Compiling documentation

GitHub will automatically compile master (edge) and any tagged releases. If a release folder already exists, the GitHub release is ignored and the source controlled version is used.

Compiled documentation lives in static/docs/api/[version]. The documentation generation works by cloning each version of Excalibur and running the npm run apidocs script. API documentation is generated in ex/[version]/docs/api and then copied to the corresponding static/docs/api/[version] folder.

Generating locally

To generate documentation locally, you can run the following command:

# Compile edge (master)
npm run docs

# Compile specific version
npm run docs -- [version]

If a version is passed, the documentation will build and output to that version's location (static/docs/api/[version]). Excalibur versions v0.10.0 and prior will not build locally and are already generated.

Git Submodules

If the showcase is in Git and can be run in a sub-directory, you can initialize a submodule in the showcase directory.

git submodule add {clone url} showcase/{showcase name}

Example:

git submodule add https://github.com/eonarheim/Excalibur-Shmup showcase/shmup

This is how we can include the Shoot 'Em Up demo without maintaining two versions.
