Debugging

• Any view subclass, node class, and many other maestro views have a __debug flag, which when checked will dump m, and vm onto the node. This makes it easy to debug:
  • Properties that are not visible on the node (e.g. in m)
  • The current state of the vm
  • Bindings and observables that are set up
• The mioc container is stored on the MaineScene in the __mioc field

• Generated code is stored in maestro/components/generated
• If you want to delve into the generated code for whatever reason, bare in mind that, it is easy to simply open your build folder in vscode, then check the file, bearing in mind:
  • Maestro generates brs and xml files for NodeClasses and Tasks
  • Maestro generates a codebehind file (.brs) for an xml file, with a vm, if there was no codebehind
  • Maestro injects code into codebehind files (generated, or not), to wire up bindings
  • Maestro injects code into non-vm code-behind file, to create variables for all nodes with ids
  • Maestro removes any xml values from nodes that contained binding information

If maestro is giving you a hard time, and you want to be able to jump into the brighterscript source:

• clone the maestro-roku ropm package on your machine
• build maestro-roku with source maps enabled:
  • npm run build-local
• in your project that is using maestro, edit the ropm package import in your package.json to be:
  • "maestro": "file:/PATH/TO/WHERE/YOU/CLONED/maestro-roku"
• ropm copy in your project's folder
• you are now using a local copy of maestro with source maps. Happy bug hunting! Please feel free to submit prs :)
