Description

Utilities for working with code blocks.

Synopsis

unTag :: Text -> (Maybe Text, Text)
onTag :: Text -> (Attr -> Text -> a) -> (Block -> a) -> Block -> a

Documentation

unTag :: Text -> (Maybe Text, Text) Source #

Given a block, if it begins with a tag in square brackets, strip off the tag and return a pair consisting of the tag and de-tagged block. Otherwise, return Nothing and the unchanged block.

onTag :: Text -> (Attr -> Text -> a) -> (Block -> a) -> Block -> a Source #

Run the given function on the attributes and source code of code blocks with a tag matching the given tag (case insensitive). On any other blocks (which don't have a matching tag, or are not code blocks), run the other function.
