Dafny plugin does nothing

[damienstanton]

The plugin installs and provides syntax highlighting, however none of the operations do anything and there is no output in the Dafny VSCode output pane. There are also no errors in the devtools.

The "activating extensions" dialog shows in the lower left of the status bar (shown in this screenshot) for 1-2 seconds, and then disappears. There doesn't appear to be any other output.

My environment:

Apple M2
macOS 15.1 beta
dotnet 8.0.303
openjdk 23

I haven't seen this before. If you open something other than a .dfy file, do your VSCode extensions activate successfully?

If you look at the dropdown that in your screenshot reads "Dafny VSCode", is there any interesting information in other channels, such as "Extension Host" ?

[damienstanton]

There's nothing except a log that the extension is associated with .dfy files (which is correct of course). I have several other extensions running on this machine and have not had any issues. I'll see if I can play with the configuration to discover what's going on.

I figured it out. These values were somehow missing from the default config, highlighted in red with an error "value must be numeric".

Once I set them to 0 and restarted both the extension host and the editor, everything now works.

Given that I am on a beta OS, and that I've not seen this issue at all on my other machines, I'll close this for now.

Reopening since we could try to make the code robust against this issue
