VS code debugger does nothing when only install phoityne-vscode

[davex25]

Running vs code 1.31.1.

I eventually stumbled on needing to run stack install haskell-dap, and adding a --with-ghc=haskell-dap argument for my ghci launch config in VS code. If this is required, shouldn't it be installed as a dependency and configured to launch?

Or if not, what was I missing in order to debug without it?

This is a same issue as
phoityne/hdx4vsc#1

phoityne-vscode(haskell-debug-adapter) should work standalone.

About using haskell-dap, it is moving to use it gradually.
As you say, dependent libraries and default launch setting will be set.
