Directory structure

data Paths use

The directory structure relevant to preparing and carrying out a build plan.

Constructors

Paths

Fields

  Input fetched sources directory.

• buildPaths :: BuildPaths use

  Output build directory structure.

  NB: this will be bottom in the case that we are outputing a shell script that uses variables.

data family BuildPaths use

The directory structure relevant to executing a build plan.

Instances

data BuildPaths 'ForBuild

Defined in BuildEnv.Config

data BuildPaths 'ForBuild = BuildPaths {

data PathUsability

The appropriate stage at which to use a filepath.

Constructors

Raw

We have just parsed filepaths. They need to be canonicalised before they can be used.

ForPrep

The filepaths have been canonicalised.

They are now suitable for preparatory build instructions, but not for performing the build.

ForBuild

The paths are suitable for performing the build.

canonicalizePaths :: Compiler -> BuildStrategy -> Paths Raw -> IO (Paths ForPrep, Paths ForBuild)

Canonicalise raw Paths, computing the appropriate directory structure for preparing and executing a build, respectively.
