Text.Pandoc.Filter.Plot

Description

This module defines a Pandoc filter plotFilter 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, e.g. matplotlib for matplotlib-based Python plots.

Here is an example, in Markdown, for a plot in MATLAB:

This is a paragraph.

```{.matlabplot}
figure()
plot([1,2,3,4,5], [1,2,3,4,5], '-k')
```

or a using GNUPlot:

```{.gnuplot format=png caption="Sinusoidal function" source=true}
sin(x)

set xlabel "x"
set ylabel "y"
```

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 some of the possible attributes what pandoc-plot understands for ALL toolkits:

  • directory=... : Directory where to save the figure. This path should be specified with respect to the current working directory, and not with respect to the document.
  • source=true|false : Whether or not to link the source code of this figure in the caption. Ideal for web pages, for example. Default is false.
  • format=...: Format of the generated figure. This can be an extension or an acronym, e.g. format=PNG.
  • caption="...": Specify a plot caption (or alternate text). Format for captions is specified in the documentation for the Configuration type.
  • dpi=...: Specify a value for figure resolution, or dots-per-inch. Certain toolkits ignore this.
  • dependencies=[...]: Specify files/directories on which a figure depends, e.g. data file. Figures will be re-rendered if one of those file/directory changes. These paths should be specified with respect to the current working directory, and not with respect to the document.
  • preamble=...: Path to a file to include before the code block. Ideal to avoid repetition over many figures.
  • file=...: Path to a file from which to read the content of the figure. The content of the code block will be ignored. This path should be specified with respect to the current working directory, and not with respect to the document.

All attributes are described in the online documentation, linked on the home page.

Synopsis

Operating on whole Pandoc documents

plotFilter Source #

Arguments

:: Configuration

Configuration for default values

-> Maybe Format

Final converted format, if known

-> Pandoc

Input document

-> IO Pandoc 

Walk over an entire Pandoc document, transforming appropriate code blocks into figures. This function will operate on blocks in parallel if possible.

If the target conversion format is known, then this function can provide better defaults and error messages. For example, hyperlinks to source code will only be created if the final target format supports it (e.g. HTML).

Failing to render a figure does not stop the filter, so that you may run the filter on documents without having all necessary toolkits installed. In this case, error messages are printed to stderr, and blocks are left unchanged.

Since: 1.3.0

plotTransform Source #

Arguments

:: Configuration

Configuration for default values

-> Pandoc

Input document

-> IO Pandoc 

Deprecated: plotTransform has been deprecated in favour of plotFilter, which is aware of conversion format.plotTransform will be removed in an upcoming major update.

Walk over an entire Pandoc document, transforming appropriate code blocks into figures. This function will operate on blocks in parallel if possible.

Failing to render a figure does not stop the filter, so that you may run the filter on documents without having all necessary toolkits installed. In this case, error messages are printed to stderr, and blocks are left unchanged.

__Note that this function is DEPRECATED in favour of plotFilter. It will be removed in the next major update (v2+).__

Cleaning output directories

cleanOutputDirs :: Walkable Block b => Configuration -> b -> IO [FilePath] Source #

Clean all output related to pandoc-plot. This includes output directories specified in the configuration and in the document/block, as well as log files. Note that *all* files in pandoc-plot output directories will be removed.

The cleaned directories are returned.

Runtime configuration

configuration :: FilePath -> IO Configuration Source #

Read configuration from a YAML file. The keys are exactly the same as for code blocks.

If a key is not present, its value will be set to the default value. Parsing errors result in thrown exceptions.

defaultConfiguration :: Configuration Source #

Default configuration values.

Since: 0.5.0.0

data Configuration Source #

The Configuration type holds the default values to use when running pandoc-plot. These values can be overridden in code blocks.

You can create an instance of the Configuration type from file using the configuration function.

You can store the path to a configuration file in metadata under the key plot-configuration. For example, in Markdown:

    ---
    title: My document
    author: John Doe
    plot-configuration: pathtofile.yml
    ---

The same can be specified via the command line using Pandoc's -M flag:

pandoc --filter pandoc-plot -M plot-configuration="path/to/file.yml" ...

In this case, use configurationPathMeta to extact the path from Pandoc documents.

Version information

pandocPlotVersion :: Version Source #

The version of the pandoc-plot package.

Since: 0.8.0.0

For embedding, testing and internal purposes ONLY. Might change without notice.

make :: Block -> PlotM Block Source #

Try to process the block with `pandoc-plot`. If a failure happens (or the block) was not meant to become a figure, return the block as-is unless running in strict mode. In strict mode, any failure (for example, due to a missing plotting toolkit) will halt execution.

New in version 1.2.0: this function will detect nested code blocks, for example in Div blocks.

makeEither :: Block -> PlotM (Either PandocPlotError Block) Source #

Try to process the block with `pandoc-plot`, documenting the error. This function does not transform code blocks nested in other blocks (e.g. Divs)
