configuration :: FilePath -> IO Configuration


-- | This module defines a Pandoc filter <tt>makePlot</tt> and related
--   functions that can be used to walk over a Pandoc document and generate
--   figures from code blocks using a multitude of plotting toolkits.
--   
--   The syntax for code blocks is simple, Code blocks with the appropriate
--   class attribute will trigger the filter. For example:
--   
--   <ul>
--   <li><tt>.matplotlib</tt> for matplotlib-based Python plots;</li>
--   <li><tt>.plotly_python</tt> for Plotly-based Python plots;</li>
--   <li><tt>.matlabplot</tt> for MATLAB plots;</li>
--   <li><tt>.mathplot</tt> for Mathematica plots;</li>
--   <li><tt>.octaveplot</tt> for GNU Octave plots;</li>
--   <li><tt>.ggplot2</tt> for ggplot2-based R plots;</li>
--   </ul>
--   
--   The code block will be reworked into a script and the output figure
--   will be captured. Optionally, the source code used to generate the
--   figure will be linked in the caption.
--   
--   Here are the possible attributes what pandoc-plot understands for ALL
--   toolkits:
--   
--   <ul>
--   <li><tt>directory=...</tt> : Directory where to save the figure.</li>
--   <li><tt>source=true|false</tt> : Whether or not to link the source
--   code of this figure in the caption. Ideal for web pages, for example.
--   Default is false.</li>
--   <li><tt>format=...</tt>: Format of the generated figure. This can be
--   an extension or an acronym, e.g. <tt>format=png</tt>.</li>
--   <li><tt>caption="..."</tt>: Specify a plot caption (or alternate
--   text). Captions support Markdown formatting and LaTeX math
--   (<tt>$...$</tt>).</li>
--   <li><tt>dpi=...</tt>: Specify a value for figure resolution, or
--   dots-per-inch. Certain toolkits ignore this.</li>
--   <li><tt>preamble=...</tt>: Path to a file to include before the code
--   block. Ideal to avoid repetition over many figures.</li>
--   </ul>
--   
--   Default values for the above attributes are stored in the
--   <tt>Configuration</tt> datatype. These can be specified in a YAML
--   file.
module Text.Pandoc.Filter.Plot

-- | Highest-level function that can be walked over a Pandoc tree. All code
--   blocks that have the <tt>.plot</tt> / <tt>.plotly</tt> class will be
--   considered figures.
--   
--   The target document format determines how the figure captions should
--   be parsed. By default (i.e. if Nothing), captions will be parsed as
--   Markdown with LaTeX math <tt>$...$</tt>,
makePlot :: Configuration -> Maybe Format -> Block -> IO Block

-- | Walk over an entire Pandoc document, changing appropriate code blocks
--   into figures. Default configuration is used.
plotTransform :: Configuration -> Maybe Format -> Pandoc -> IO Pandoc

-- | Read configuration from a YAML file. The keys are exactly the same as
--   for code blocks.
--   
--   If a key is either not present, its value will be set to the default
--   value. Parsing errors result in thrown exceptions.
