It will behave the same way when invoked for executable parts of the project (this makes sense - executable needs library to  work/typecheck) or on the library itself - which means typechecker won't work if library fails to compile.\r\n\r\nA workaround is to remove executable parts from cabal file. A proper fix - try to distinguish between library and executables?","author":{"url":"https://github.com/pacak","@type":"Person","name":"pacak"},"datePublished":"2018-03-19T23:53:15.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":16},"url":"https://github.com/77/hdevtools/issues/77"}
