Module : Text.Pandoc
Copyright : Copyright (C) 2006-2010 John MacFarlane
License : GNU GPL, version 2 or above
Maintainer : John MacFarlane <jgm@berkeley.edu>
Stability : alpha
Portability : portable
This helper module exports the main writers, readers, and data
structure definitions from the Pandoc libraries.
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
> -- include the following two lines only if you're using ghc < 6.12:
> import Prelude hiding (getContents, putStrLn)
> import System.IO.UTF8
>
> markdownToRST :: String -> String
> markdownToRST =
> (writeRST defaultWriterOptions {writerReferenceLinks = True}) .
> readMarkdown defaultParserState
>
> main = getContents >>= putStrLn . markdownToRST
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')@.
