Install Plugin to the app

[issmail-basel]

Description

There are two "installation" of plugins.

1. Installing plugin to app - only required in the first time for each plugin. Note that it is treated as different plugin even if only version is different
2. Installing plugin to scene

1. Installing plugin to app

1. Fetch archive data from GitHub
   • URL is https://github.com/OWNER_NAME/REPOSTIROY_NAME/archive/BRANCH_NAME.zip but OWNER_NAME, REPOSTIROY_NAME and BRANCH_NAME will be changed for each plugin.
   • You can impl the logic in internal/infrastructure/github
2. Extract and find reearth.json file (there is partial impl in internal/infrastructure/npm)
   • You can impl the logic in internal/infrastructure/github
3. Parse it with pkg/plugin/manifest and you'll get plugin.Plugin struct and some property.Schema structs. If no error, you can save them (plugin and property schemas).
   • You can impl the logic in pkg/scene/sceneops (e.g. PluginInstaller)

• PluginMetadata: created
• PluginInstaller
  • Accept any gateway.PluginRepository in constructor
  • func Install(PluginMetadata) (manifest.Manifest, error)
• internal/infrastructure/github

2. Installing plugin to scene

You can implement the following in usecase layer.

1. Load the scene
2. Add a new plugin to scene.PluginSystem
3. If the same plugin is already installed, an error should be occurred.
