[code] Concept test for "Import All File Types" command

Developers Ruby API

Continuing the discussion from Import - view all supported file types:

Just some test code to test the concept of the feature requested in the linked thread.

  • MS Windows only
  • Does not save paths from session to session
  • Does not manipulate the individual filetype’s import settings

Just a note after thinking a bit.

There is no way using the Ruby API that code can know what type of import file is chosen within the file open dialog in order to tailor the options sub-dialog to the unique import settings.

So such generic import commands would either (a) as the simple test does, rely solely upon the user’s previous settings for that file type (or SketchUp’s defaults if the user never yet imported this filetype,) …
or (b) always bring up a custom file import dialog after the user selects the file to import (as the code can only respond to the file type by “sniffing” the file extension from the path string returned by the file open dialog.)

So as I think the simple API UI.inputbox would be inadequate, and a browser dialog too much work for a test, I didn’t do this. @thomthom had some code in his GitHub repo that might be adapted to this.

ADD (a day later) : In case the reader wondered, we cannot use Sketchup::Importer subclass objects as they only support a single file type extension. (See the class’ #file_extension getter method. This method is used to create the filtered listing that appears in the file selection browser dialog.)
