sCHEMA_VERSION :: Integer Source #

dB_VERSION :: Integer Source #

checkVersion :: (HieDb -> IO a) -> HieDb -> IO a Source #

checkVersion f db checks the schema version associated with given db. If that version is supported by hiedb, it runs the function f with the db. Otherwise it throws IncompatibleSchemaVersion exception.

withHieDb :: FilePath -> (HieDb -> IO a) -> IO a Source #

Given path to .hiedb file, constructs HieDb and passes it to given function.

withHieDbAndFlags :: LibDir -> FilePath -> (DynFlags -> HieDb -> IO a) -> IO a Source #

Given GHC LibDir and path to .hiedb file, constructs DynFlags (required for printing info from .hie files) and HieDb and passes them to given function.

initConn :: HieDb -> IO () Source #

Initialize database schema for given HieDb.

addArr :: HieDb -> Array TypeIndex HieTypeFlat -> IO (Array TypeIndex (Maybe Int64)) Source #

Add names of types from .hie file to HieDb. Returns an Array mapping TypeIndex to database ID assigned to the corresponding record in DB.

addTypeRefs Source #

Arguments

:: HieDb
-> FilePath	Path to `.hie` file
-> HieFile	Data loaded from the `.hie` file
-> Array TypeIndex (Maybe Int64)	Maps TypeIndex to database ID assigned to record in `typenames` table
-> IO ()

Add references to types from given .hie file to DB.

addRefsFrom :: (MonadIO m, NameCacheMonad m) => HieDb -> FilePath -> m Bool Source #

Adds all references from given .hie file to HieDb. The indexing is skipped if the file was not modified since the last time it was indexed. The boolean returned is true if the file was actually indexed

addRefsFromLoaded Source #

Arguments

:: MonadIO m
=> HieDb	HieDb into which we're adding the file
-> FilePath	Path to `.hie` file
-> SourceFile	Path to .hs file from which `.hie` file was created Also tells us if this is a real source file? i.e. does it come from user's project (as opposed to from project's dependency)?
-> Fingerprint	The hash of the `.hie` file
-> HieFile	Data loaded from the `.hie` file
-> m ()

addRefsFromLoaded_unsafe Source #

Arguments

:: MonadIO m
=> HieDb	HieDb into which we're adding the file
-> FilePath	Path to `.hie` file
-> SourceFile	Path to .hs file from which `.hie` file was created Also tells us if this is a real source file? i.e. does it come from user's project (as opposed to from project's dependency)?
-> Fingerprint	The hash of the `.hie` file
-> HieFile	Data loaded from the `.hie` file
-> m ()

Like addRefsFromLoaded but without: 1) using a transaction 2) cleaning up previous versions of the file

Mostly useful to index a new database from scratch as fast as possible

addSrcFile Source #

Arguments

:: HieDb
-> FilePath	Path to `.hie` file
-> FilePath	Path to .hs file to be added to DB
-> Bool	Is this a real source file? I.e. does it come from user's project (as opposed to from project's dependency)?
-> IO ()

Add path to .hs source given path to .hie file which has already been indexed. No action is taken if the corresponding .hie file has not been indexed yet.

deleteFileFromIndex :: HieDb -> FilePath -> IO () Source #

Delete all occurrences of given .hie file from the database

deleteMissingRealFiles :: HieDb -> IO () Source #

Delete all entries associated with modules for which the modInfoSrcFile doesn't exist on the disk. Doesn't delete it if there is no associated modInfoSrcFile

garbageCollectTypeNames :: HieDb -> IO Int Source #

Garbage collect typenames with no references - it is a good idea to call this function after a sequence of database updates (inserts or deletes)

deleteInternalTables :: Connection -> FilePath -> IO () Source #
