Ruby Importer API Crash

[Jim]

Sang Ahn has posted an introduction to the SketchUp Ruby Importer API on the SketchUp API Blog. The API allows you to put your import in the File > Importers menu, for one.

However, my simple test of the API crashes SU repeatably. Can anyone confirm the following code crashes SketchUp? If so, I'll file a bug report.

You can see the importer does appear in the correct menu:

But here is the result just before BugSplat:

Here's the code. You can see all it does is print the file:

class JfObjImporter
  def description
    # Returns a brief description of your importer plugin.
    "JF OBJ Importer (*.obj)"
  end
  def file_extension
    # Returns the file extension of the file format your
    # importer can read (e.g. fbx, dae, etc.)
    "obj"
  end
  def supports_options?
    # Returns true if your plugin supports import options.
    false
  end
  def do_options
    # Presents the import options dialog panel to the user.
  end
  def id
    # Returns the id string of your importer.
    "JFimporterID"
  end
  def load_file(file_name, show_summary)
    # Reads the contents of location on disk specified by file_name.
    # Shows the summary dialog panel if show_summary is true.
    p file_name
    IO.readlines(file_name).each do |line|
      puts line
    end
  end
end

Sketchup.register_importer JfObjImporter.new

Here's the file:

I left out an importer detail in the blog post.

load_file

needs a return code. Returns 0 on success, 1 on error. D'oh!

That fixed it! Thank you, Sang.
