lookupHeaders :: MonadHandler m => CI ByteString -> m [ByteString]hledger-web Hledger.Web.Import Lookup a request header.
lookupPostParam :: (MonadResource m, MonadHandler m) => Text -> m (Maybe Text)hledger-web Hledger.Web.Import No documentation available.
lookupPostParams :: (MonadResource m, MonadHandler m) => Text -> m [Text]hledger-web Hledger.Web.Import Lookup for POST parameters.
lookupRawFieldInput :: MonadHandler m => Text -> m [Text]hledger-web Hledger.Web.Import The raw parameter values the named field was run against in this request, whether from a direct submission or a Post/Redirect/Get replay (runFormPRG). Empty if no form containing the field has run with a submission in this request (e.g. generateFormPost, or an identifyForm-wrapped form that was not the one submitted). This lets the view of a field rendering several inputs under one name restore all of the user's raw input after a failed submission: the Either Text a argument a view receives can only carry the first submitted value. Only fields run through mreq/mopt (and the applicative/widget helpers built on them) record their values here.
lookupSession :: MonadHandler m => Text -> m (Maybe Text)hledger-web Hledger.Web.Import Lookup for session data.
lookupSessionBS :: MonadHandler m => Text -> m (Maybe ByteString)hledger-web Hledger.Web.Import Lookup for session data in binary format.
lookupKey :: ByteString -> HashMap ByteString a -> Maybe ahpp Hpp.Env No documentation available.
lookupMacro :: (HasEnv m, Monad m) => String -> m (Maybe Macro)hpp Hpp.Types Looks up a Macro in the current environment. If the Macro is found, the environment is juggled so that subsequent lookups of the same Macro may evaluate more quickly.
