Documentation
getLabel :: Lazyboy Integer Source #
Get a label, and in the process increment the counter used to track labels. this provides a safe interface to label retrieval and utilization.
getLocalLabel :: Lazyboy Label Source #
Get a local label. The name is guaranteed to be unique.
getGlobalLabel :: Lazyboy Label Source #
Get a global label. The name is guaranteed to be unique.
withLabel :: (Label -> Lazyboy ()) -> Lazyboy () Source #
Execute an action within a global label and pass the action the label.
withLocalLabel :: (Label -> Lazyboy ()) -> Lazyboy () Source #
Execute an action within a local label and pass the action the label.
embedFile :: FilePath -> Lazyboy Label Source #
Embed a file and return a global label for it. A jump over the block of data is added to prevent the image data being executed.
embedImage :: FilePath -> Lazyboy Label Source #
Embed an image and return a (global) label for it. A jump over the block of data is added to prevent the image data being executed.
