I’m going through the tutorial for writing shell extensions in TypeScript, and the example provided doesn’t compile.
It fails with a wall of “Duplicate identifier” errors between symbols exported in @girs/... modules. And a bunch of incompatibilities between ...Paintable types. The forum only allows images or pdf attachments, so I pasted some of the errors at the end.
Despite the errors, the dist/*.js files still gets created, so running make install a second time manages to install the extension.
After installing, the extension enables and disables normally, but trying to access the preferences with gnome-extension prefs ... crashes with this error screen:
The same issue has been observed by other users on Gnome Extensions matrix chat, and on the TypeScript discord server. It looks to be an actual problem in the example.
