Description

I have several extensions enabled in my package.yaml file in the default-extensions field (e.g. DerivingStrategies), so floskell fails to parse the source file (on seeing deriving stock for example) and reports a syntax error.

Is there any possibility that we automatically detect the default-extensions field in package.yaml file and pass them to floskell? Or perhaps by default enabling some extensions that in general don't break otherwise well-formed programs (e.g. DerivingStrategies, StandaloneDeriving, etc.)?

Contributor guide

Research direction
Locate where Floskell is invoked in the HIE codebase, then add logic to read default extensions from package.yaml and pass them to Floskell.
