Package info

data PkgInfo m Source #

Information about a package. The name of the package is stored separately.

Constructors

PkgInfo
Fields pkgVersions :: Map SemVer (PkgRevInfo m) pkgLookupCommit :: Maybe Text -> m (PkgRevInfo m) Look up information about a specific commit, or HEAD in case of Nothing.

lookupPkgRev :: SemVer -> PkgInfo m -> Maybe (PkgRevInfo m) Source #

pkgInfo :: (MonadIO m, MonadLogger m) => PkgPath -> m (Either Text (PkgInfo m)) Source #

Retrieve information about a package based on its package path. This uses Semantic Import Versioning when interacting with repositories. For example, a package github.comuserrepo will match version 0.* or 1.* tags only, a package github.comuserrepo/v2 will match 2.* tags, and so forth..

data PkgRevInfo m Source #

Information about a version of a single package. The version number is stored separately.

Constructors

PkgRevInfo

Fields

pkgRevZipballUrl :: Text
pkgRevZipballDir :: FilePath
The directory inside the zipball containing the lib directory, in which the package files themselves are stored (Based on the package path).
pkgRevCommit :: Text
The commit ID can be used for verification ("freezing"), by storing what it was at the time this version was last selected.
pkgRevGetManifest :: GetManifest m
pkgRevTime :: UTCTime
Timestamp for when the revision was made (rarely used).

Instances

Eq (PkgRevInfo m) Source #
Instance details Defined in Futhark.Pkg.Info Methods (==) :: PkgRevInfo m -> PkgRevInfo m -> Bool # (/=) :: PkgRevInfo m -> PkgRevInfo m -> Bool #
Show (PkgRevInfo m) Source #
Instance details Defined in Futhark.Pkg.Info Methods showsPrec :: Int -> PkgRevInfo m -> ShowS # show :: PkgRevInfo m -> String # showList :: [PkgRevInfo m] -> ShowS #

data GetManifest m Source #

The manifest is stored as a monadic action, because we want to fetch them on-demand. It would be a waste to fetch it information for every version of every package if we only actually need a small subset of them.

Instances

downloadZipball :: (MonadLogger m, MonadIO m) => Text -> m Archive Source #

Package registry

data PkgRegistry m Source #

A package registry is a mapping from package paths to information about the package. It is unlikely that any given registry is global; rather small registries are constructed on-demand based on the package paths referenced by the user, and may also be combined monoidically. In essence, the PkgRegistry is just a cache.

Instances

Semigroup (PkgRegistry m) Source #
Instance details Defined in Futhark.Pkg.Info Methods (<>) :: PkgRegistry m -> PkgRegistry m -> PkgRegistry m # sconcat :: NonEmpty (PkgRegistry m) -> PkgRegistry m # stimes :: Integral b => b -> PkgRegistry m -> PkgRegistry m #
Monoid (PkgRegistry m) Source #
Instance details Defined in Futhark.Pkg.Info Methods mempty :: PkgRegistry m # mappend :: PkgRegistry m -> PkgRegistry m -> PkgRegistry m # mconcat :: [PkgRegistry m] -> PkgRegistry m #

class (MonadIO m, MonadLogger m) => MonadPkgRegistry m where Source #

Monads that support a stateful package registry. These are also required to be instances of MonadIO because most package registry operations involve network operations.
