Arguments
| :: (StackMiniM env m, HasConfig env) | |
| => EnvOverride | |
| -> FilePath | destination |
| -> [String] | names or identifiers |
| -> m () |
Intended to work for the command line command.
Arguments
| :: (StackMiniM env m, HasConfig env) | |
| => EnvOverride | |
| -> Path Abs Dir | unpack directory |
| -> Maybe (Path Rel Dir) | the dist rename directory, see: https://github.com/fpco/stack/issues/157 |
| -> Map PackageIdentifier (Maybe GitSHA1) | |
| -> m (Map PackageIdentifier (Path Abs Dir)) |
Ensure that all of the given package idents are unpacked into the build unpack directory, and return the paths to all of the subdirectories.
fetchPackages :: (StackMiniM env m, HasConfig env) => EnvOverride -> Set PackageIdentifier -> m () Source
Fetch packages into the cache without unpacking
untar :: forall b1 b2. Path b1 File -> Path Rel Dir -> Path b2 Dir -> IO [(FilePath, Text)] Source
Internal function used to unpack tarball.
Takes a path to a .tar.gz file, the name of the directory it should contain, and a destination folder to extract the tarball into. Returns unexpected entries, as pairs of paths and descriptions.
resolvePackages :: (StackMiniM env m, HasConfig env) => EnvOverride -> Map PackageIdentifier (Maybe GitSHA1) -> Set PackageName -> m (Map PackageIdentifier ResolvedPackage) Source
Resolve a set of package names and identifiers into FetchPackage values.
resolvePackagesAllowMissing :: (StackMiniM env m, HasConfig env) => Map PackageIdentifier (Maybe GitSHA1) -> Set PackageName -> m (Set PackageName, Set PackageIdentifier, Map PackageIdentifier ResolvedPackage) Source

withCabalFiles :: (StackMiniM env m, HasConfig env) => IndexName -> [(PackageIdentifier, PackageCache, Maybe GitSHA1, a)] -> (PackageIdentifier -> a -> ByteString -> IO b) -> m [b] Source
Add the cabal files to a list of idents with their caches.
withCabalLoader :: (StackMiniM env m, HasConfig env, MonadBaseUnlift IO m) => EnvOverride -> ((PackageIdentifier -> IO ByteString) -> m a) -> m a Source
Provide a function which will load up a cabal ByteString from the
package indices.
