A typical application will chain together a reader and a writer to convert strings from one format to another. For example, the following simple program will act as a filter converting markdown fragments to reStructuredText, using reference-style links instead of inline links: > module Main where > import Text.Pandoc > > markdownToRST :: String -> Either PandocError String > markdownToRST = > writeRST def {writerReferenceLinks = True} . readMarkdown def > > main = getContents >>= either error return markdownToRST >>= putStrLn Note: all of the readers assume that the input text has @'\n'@ line endings. So if you get your input text from a web form, you should remove @'\r'@ characters using @filter (/='\r')@. -} module Text.Pandoc ( -- * Definitions module Text.Pandoc.Definition -- * Generics ,
