findVersion
:: GlobalCache -> String -> (Int,Int,Int,Maybe String) -> Maybe Package
Finds a specific version of a package. |
installedPackageDir
:: Config -> Package -> String
The directory of a package in the global package cache. |
packageInstalled
:: Config -> Package -> IO Bool
Checks whether a package is installed in the global cache. |
copyPackage
:: Config -> Package -> String -> IO ([LogEntry],Either LogEntry ())
Copy a package version to a directory. |
acquireAndInstallPackage
:: Config -> Package -> ErrorLoggerIO ()
Acquires a package, either from the global tar file repository or from the source specified in its specification, and installs it to the global package cache. |
acquireAndInstallPackageFromSource
:: 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] -> ErrorLoggerIO ()
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 -> Package -> ErrorLoggerIO ()
Checkout a package from the global package cache. |
uninstallPackage
:: Config -> String -> (Int,Int,Int,Maybe String) -> ErrorLoggerIO ()
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. |
readGlobalCache
:: Config -> Repository -> ErrorLoggerIO GlobalCache
Reads the global package cache. |
readInstalledPackagesFromDir
:: Repository -> String -> IO (Either String GlobalCache)
Tries to read package specifications from a GC directory structure. |
The data type representing the global package cache.
Constructors:
An empty package cache.
|
Gets all package specifications from a cache.
|
Finds all versions of a package in the global package cache.
|
Finds the newest version of a package. |
Finds a specific version of a package. |
The directory of a package in the global package cache. Does not check whether the package is actually installed! |
Checks whether a package is installed in the global cache. |
Copy a package version to a directory. |
Acquires a package, either from the global tar file repository or from the source specified in its specification, and installs it to the global package cache. |
Acquires a package from the source specified in its specification and installs it to the global package cache. |
Installs a package from a ZIP file to the global package cache. |
Installs a package's missing dependencies. |
Filters a list of packages to the ones not installed in the global package cache. |
Checkout a package from the global package cache. |
Removes a package from the global package cache. |
Tries to find a package in the global package cache. |
Reads the global package cache. |
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. |
