They are packaged as zipped Widgets (with extension .widget) inside a zipped folder. The code can be examined by unzipping the .widget files.
Download figures are the final download counts at the close of the Yahoo! Widget Gallery.
N.B. The Widget Engine runs fully correctly on OS X versions up to and including 10.10.5 (Yosemite). It does not run fully correctly on OS X 10.11 (El Capitan), on macOS 10.12 (Sierra) or on macOS 10.13 (High Sierra).
On the later versions of macOS (10.11, 10,12 and 10.13), almost all of the functions of the Widget Engine can be used successfully, if the Widget Dock is kept closed.
If the dock cannot be closed from the menubar, the Yahoo! Widgets preference file can be edited (while the Engine is not running) to set DockOpen to false, so that the dock does not open when the Widget Engine is started.
The preference file is normally at ~/Library/Preferences/com.yahoo.widgetengine.plist and can be edited using BBEdit, TextWrangler and Xcode.
The canvas context.drawImage(...) function no longer works. It is also not possible to run Widgets with an open debug window on El Capitan and Sierra.
Nevertheless, most/many Widgets can be used successfully.
