Documentation

data TempFileLifetime Source #

Used when a temp file is created. This determines which component Set of FilesToClean will get the temp file

Constructors

TFL_CurrentModule	A file with lifetime TFL_CurrentModule will be cleaned up at the end of upweep_mod
TFL_GhcSession	A file with lifetime TFL_GhcSession will be cleaned up at the end of runGhc(T)

Instances

Show TempFileLifetime Source #
Instance details Defined in FileCleanup Methods showsPrec :: Int -> TempFileLifetime -> ShowS Source # show :: TempFileLifetime -> String Source # showList :: [TempFileLifetime] -> ShowS Source #

cleanTempDirs :: DynFlags -> IO () Source #

cleanTempFiles :: DynFlags -> IO () Source #

Delete all files in filesToClean dflags.

cleanCurrentModuleTempFiles :: DynFlags -> IO () Source #

Delete all files in filesToClean dflags. That have lifetime TFL_CurrentModule. If a file must be cleaned eventually, but must survive a cleanCurrentModuleTempFiles, ensure it has lifetime TFL_GhcSession.

addFilesToClean :: DynFlags -> TempFileLifetime -> [FilePath] -> IO () Source #

Ensure that new_files are cleaned on the next call of cleanTempFiles or cleanCurrentModuleTempFiles, depending on lifetime. If any of new_files are already tracked, they will have their lifetime updated.

changeTempFilesLifetime :: DynFlags -> TempFileLifetime -> [FilePath] -> IO () Source #

Update the lifetime of files already being tracked. If any files are not being tracked they will be discarded.

newTempName :: DynFlags -> TempFileLifetime -> Suffix -> IO FilePath Source #

newTempLibName :: DynFlags -> TempFileLifetime -> Suffix -> IO (FilePath, FilePath, String) Source #

withSystemTempDirectory Source #

Arguments

:: String	Directory name template. See `openTempFile`.
-> (FilePath -> IO a)	Callback that can use the directory
-> IO a

Create and use a temporary directory in the system standard temporary directory.

Behaves exactly the same as withTempDirectory, except that the parent temporary directory will be that returned by getTemporaryDirectory.

withTempDirectory Source #

Arguments

:: FilePath	Temp directory to create the directory in
-> String	Directory name template. See `openTempFile`.
-> (FilePath -> IO a)	Callback that can use the directory
-> IO a

Create and use a temporary directory.

Creates a new temporary directory inside the given directory, making use of the template. The temp directory is deleted after use. For example:

withTempDirectory "src" "sdist." $ \tmpDir -> do ...

The tmpDir will be a new subdirectory of the given directory, e.g. src/sdist.342.
