Module CPM.PackageCache.Global

emptyCache :: GlobalCache   

An empty package cache.

Further infos:

• solution complete, i.e., able to compute all solutions

allPackages :: GlobalCache -> [Package]   

Gets all package specifications from a cache.

Further infos:

• solution complete, i.e., able to compute all solutions

findAllVersions :: GlobalCache -> String -> Bool -> [Package]   

Finds all versions of a package in the global package cache.

Example call:

(findAllVersions gc p pre)

Parameters:

• gc : the global package cache
• p : the name of the package
• pre : include pre-release versions

findNewestVersion :: GlobalCache -> String -> Maybe Package   

Finds the newest version of a package.

findVersion :: GlobalCache -> String -> (Int,Int,Int,Maybe String) -> Maybe Package   

Finds a specific version of a package.

isPackageInstalled :: GlobalCache -> Package -> Bool   

Checks whether a package is installed.

installedPackageDir :: Config -> Package -> String   

The directory of a package in the global package cache. Does not check whether the package is actually installed!

copyPackage :: Config -> Package -> String -> IO ([LogEntry],Either LogEntry ())   

Copy a package version to a directory.

acquireAndInstallPackage :: Config -> Package -> IO ([LogEntry],Either LogEntry ())   

Acquires a package from the source specified in its specification and installs it to the global package cache.

installFromZip :: Config -> String -> IO ([LogEntry],Either LogEntry ())   

Installs a package from a ZIP file to the global package cache.

installMissingDependencies :: Config -> GlobalCache -> [Package] -> IO ([LogEntry],Either LogEntry ())   

Installs a package's missing dependencies.

missingPackages :: GlobalCache -> [Package] -> [Package]   

Filters a list of packages to the ones not installed in the global package cache.

checkoutPackage :: Config -> Repository -> GlobalCache -> Package -> IO ([LogEntry],Either LogEntry ())   

Checkout a package from the global package cache.

uninstallPackage :: Config -> Repository -> GlobalCache -> String -> (Int,Int,Int,Maybe String) -> IO ([LogEntry],Either LogEntry ())   

Removes a package from the global package cache.

tryFindPackage :: GlobalCache -> String -> (Int,Int,Int,Maybe String) -> IO ([LogEntry],Either LogEntry Package)   

Tries to find a package in the global package cache.

readInstalledPackagesFromDir :: Repository -> String -> IO (Either String GlobalCache)   

Tries to read package specifications from a GC directory structure. If some GC package directory has the same name as a package from the repository index, the package specification from the repository is used, otherwise (this case should not occur) the package specification stored in the directory is read. This should result in faster GC loading.
