This module deals with finding imported modules and loading their interface files.



data MainInterface Source

Are we loading the interface for the user-loaded file or for an import?



Interface for main file.


Interface for imported file.

mergeInterface :: Interface -> TCM () Source

Merge an interface into the current proof state.

scopeCheckImport :: ModuleName -> TCM (ModuleName, Map ModuleName Scope) Source

Scope checks the given module. A proper version of the module name (with correct definition sites) is returned.

alreadyVisited :: TopLevelModuleName -> TCM (Interface, MaybeWarnings) -> TCM (Interface, MaybeWarnings) Source

If the module has already been visited (without warnings), then its interface is returned directly. Otherwise the computation is used to find the interface and the computed interface is stored for potential later use.

typeCheckMain :: AbsolutePath -> TCM (Interface, MaybeWarnings) Source

Type checks the main file of the interaction. This could be the file loaded in the interacting editor (emacs), or the file passed on the command line.

First, the primitive modules are imported. Then, getInterface' is called to do the main work.

getInterface :: ModuleName -> TCM Interface Source

Tries to return the interface associated to the given (imported) module. The time stamp of the relevant interface file is also returned. Calls itself recursively for the imports of the given module. May type check the module. An error is raised if a warning is encountered.

Do not use this for the main file, use typeCheckMain instead.

getInterface' Source


:: TopLevelModuleName 
-> MainInterface

If type checking is necessary, should all state changes inflicted by createInterface be preserved?

-> TCM (Interface, MaybeWarnings) 

A more precise variant of getInterface. If warnings are encountered then they are returned instead of being turned into errors.

highlightFromInterface Source


:: Interface 
-> AbsolutePath

The corresponding file.

-> TCM () 

Print the highlighting information contained in the given interface.

writeInterface :: FilePath -> Interface -> TCM () Source

Writes the given interface to the given file. Returns the file's new modification time stamp, or Nothing if the write failed.

createInterface Source


:: AbsolutePath

The file to type check.

-> TopLevelModuleName

The expected module name.

-> TCM (Interface, MaybeWarnings) 

Tries to type check a module and write out its interface. The function only writes out an interface file if it does not encounter any warnings.

If appropriate this function writes out syntax highlighting information.

buildInterface Source


:: AbsolutePath 
-> TopLevelInfo

TopLevelInfo for the current module.

-> HighlightingInfo

Syntax highlighting info for the module.

-> Set String

Haskell modules imported in imported modules (transitively).

-> [OptionsPragma]

Options set in OPTIONS pragmas.

-> TCM Interface 

Builds an interface for the current module, which should already have been successfully type checked.

getInterfaceFileHashes :: FilePath -> TCM (Maybe (Hash, Hash)) Source

Returns (iSourceHash, iFullHash)

isNewerThan :: FilePath -> FilePath -> IO Bool Source

True if the first file is newer than the second file. If a file doesn't exist it is considered to be infinitely old.
