The information required for a build computation which is available right before building each component, i.e. the pre-build component inputs.
PreBuildComponentInputsbuildingWhat :: BuildingWhatWhat kind of build are we doing?
localBuildInfo :: LocalBuildInfoInformation about the package
targetInfo :: TargetInfoInformation about an individual component
Get the Verbosity from the context the component being built is in.
Get the Component being built.
Is the Component being built a Library
Get the ComponentLocalBuildInfo for the component being built.
Get the BuildInfo of the component being built.
Get the Compiler being used to build the component.
What kind of build phase are we doing/hooking into?
Is this a normal build, or is it perhaps for running an interactive session or Haddock?
BuildNormal BuildFlagsA normal build.
BuildRepl ReplFlagsBuild steps for an interactive session.
BuildHaddock HaddockFlagsBuild steps for generating documentation.
BuildHscolour HscolourFlagsBuild steps for Hscolour.

to LocalBuildInfo being split into LocalBuildDescr and LocalBuildConfig.
The TargetInfo contains all the information necessary to build a
specific target (e.g., componentmodulefile) in a package. In
principle, one can get the Component from a
ComponentLocalBuildInfo and LocalBuildInfo, but it is much more
convenient to have the component in hand.
