Using multiple blueprint files (partials)

The blueprint.json files offer tremendous opportunity from a scaffolding and programmatic standpoint to developers using WordPress Playground. What if it were possible to chain together multiple blueprints to create an instance?

Use case: Build Playground docs for WordPress Plugin development

I want to see all documentation tagged plugin developer

User goes to documentation, searches "develop plugins with Playground" and finds a list of all the documentation that is tagged with plugin developer.

Docs: Creating a Plugin with WordPress Playground (post_title)
Steps: (post_content) - see below - raw .json
Description: Importing multiple WXR files to build a catalog of posts (post_excerpt)

Pseudocode

• InstallTheme schoolyard
• LoginStep
• ImportWXR getting-started-with-plugin-development-in-playground.wxr
• ImportWXR understanding-plugin-headers.wxr
• ImportWXR plugin-activation-hooks.wxr
• ImportWXR plugin-deactivation-hooks.wxr
• ImportWXR plugin-uninstall-hooks.wxr
• ImportWXR plugin-security-best-practices.wxr
• ImportWXR plugin-translation-best-practices.wxr
• ImportWXR plugin-licensing-best-practices.wxr
• InstallPluginStep create-plugin
• InstallPluginStep plugin-review-check.zip
• InstallPluginStep plugin-security-check.zip
• ActivatePluginStep create-plugin
• ActivatePluginStep plugin-review-check
• ActivatePluginStep plugin-security-check
• ImportWXR submit-plugin-for-review.wxr
• LandingPage /

Now the user will come to the Schoolyard theme, and see the documentation for creating a plugin with WordPress Playground, with Step by Step instructions for building a WordPress Plugin.

Limitations

ImportXWR isn't implemented

Currently ImportWXR does not exist as a step in the blueprint.json file. This step could be implemented simply with a WPCLIStep and import command, and link to a WXR file in the assets directory.

Blueprint parser extended

New functionality would have to be created to chain blueprint.json files.

Creating this Step would open the door to building out documentation based on user needs in lieu of having a bunch of extra docs. For example, a new user to WordPress does not need to understand how to run Playground through a web socket.

Conclusion

Being able to chain blueprints together would open up the ability to add "partial" blueprints, which could be used modularly to build out a Playground instance.

Start by locating the blueprint parser and the existing WPCLIStep handling described in the issue, along with the assets directory used for WXR files. Define how partial blueprint files would be chained and how the proposed ImportWXR step would behave, then validate the design against the documented plugin-development sequence.
