data Runner

Monadic environment.

Constructors

Runner

Fields

• runnerReExec :: !Bool
• runnerLogOptions :: !LogOptions
• runnerTerminal :: !Bool
• runnerSticky :: !Sticky
• runnerParsedCabalFiles :: !(IORef (Map PackageIdentifierRevision GenericPackageDescription, Map (Path Abs Dir) (GenericPackageDescription, Path Abs File)))

  Cache of previously parsed cabal files.

  TODO: This is really an ugly hack to avoid spamming the user with warnings when we parse cabal files multiple times and bypass performance issues. Ideally: we would just design the system such that it only ever parses a cabal file once. But for now, this is a decent workaround. See: https://github.com/commercialhaskell/stack/issues/3591.
