Changelog for pandoc-plot-0.9.1.0

Change log

Release 0.9.1.0

Added the file parameter, which allows the user to read figure content from a file instead of using the code block content in documents. This is especially useful for complex figures, where you might want to have the help of your tooling in an IDE, for instance. Here's an example:


```{.matplotlib file=myplot.py}
```

Better error messages when specifying logger verbosity.
Cleaning output directories with pandoc-plot clean now follows configuration values for logging.
Fixed an issue where configuration in metadata did not get parsed properly.

Release 0.9.0.0

The bokeh toolkit now supports exporting plots as SVGs (#8).
Interactive plots relying on javascript scripts will now defer loading the scripts (#9).
Added the dependencies argument, which tells pandoc-plot what files are important to a particular figure (#10). If a file listed in dependencies changes (for example, a data file), pandoc-plot will re-render the associated figure.
Better heuristic to determine what bokeh plot to save. This allows the user to export plots like the bokeh.layouts module.
Added support for the dpi parameter in graphviz and mathematica.
Added support for MATLAB's new exportgraphics function introduced in MATLAB 2020a. Older versions fallback to using saveas.

Release 0.8.1.0

The module Text.Pandoc.Filter.Plot.Internal is no longer exposed; instead, everything relevant is exposed by the Text.Pandoc.Filter.Plot module.
Fixed an issue where script errors would be logged as debug messages.
Interactive plots are now embedded directly in output (#7).

Release 0.8.0.0

Added a new output format, HTML, to produce interactive plots. Not all renderers support it. You can try with Plotly/Python and Plotly/R as follows:


```{.plotly_python format=html}
import plotly.express as px
df = px.data.election()
fig = px.scatter_ternary(df, a="Joly", b="Coderre", c="Bergeron")
```

Added a new toolkit, bokeh. This toolkit can take advantage of the new HTML interactive output.
Added a new toolkit, plotsjl.
Separated the detailed information from README.md and into a proper MANUAL.md. This is now the information which will be shown with pandoc-plot --manual.
Exposed the pandoc-plot version via Text.Pandoc.Filter.Plot.pandocPlotVersion.

Release 0.7.2.1

Fixed an issue where the pandoc version was not parsed properly, giving rise to errors when running pandoc-plot.
Fixed an issue where logging errors were not always displayed.

Release 0.7.2.0

Removed dependency on open-browser package.
Starting with this version, pandoc 2.8 and 2.9 are no longer supported due to a breaking API change in pandoc 2.10.
Executables are now built with GHC 8.10.1.

Release 0.7.1.0

Better multi-threaded logging. Only one thread (the logging thread) performs IO on the log file. This prevents hang-ups when working on large documents.

Release 0.7.0.0

Added documentation on using pandoc-plot with LaTeX documents as well.
Added preliminary support for logging to pandoc-plot. You can turn on this feature in the configuration as follows:

logging:
    # Possible verbosity values: debug, error, warning, info, silent
    # debug level shows all messages
    # error level shows all but debug messages, etc.
    verbosity: info
    
    # OPTIONAL: log to file
    # Remove line below to log to stderr
    filepath: log.txt

Removed dependencies turtle, temporary, deepseq, and data-default-class, resulting in improved build times by ~10%, and makes the executable smaller by 15-20%!

Release 0.6.1.0

Made the functions availableToolkits and unavailableToolkits public.
Minor documentation fixes.
Executables are now built with GHC 8.8.3.

Release 0.6.0.0

New toolkits:

Added support for the Plotly/R plotting library.
Added support for Graphviz.

Other changes:

The determination of which figures to re-render or not has been improved. For example, changing the caption will not trigger a re-render of a figure anymore.
pandoc-plot will look for executables more thoroughly.
pandoc-plot toolkits will now show the exact executable that is being used, if possible.
Added a check when running the filter that the Pandoc version is at least 2.8. This is easier to understand that the default Pandoc warning on API incompatibility.
Added the ability to write the example configuration to an arbitrary file using pandoc-plot write-example-config.
Added the possibility to specify the configuration file via metadata. For example, in Markdown:
```
---
title: My document
author: John Doe
plot-configuration: /path/to/file.yml
---     
```

or on the command line:

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

Added the ability to specify configuration file to the pandoc-plot clean and pandoc-plot toolkits commands.

Release 0.5.0.0

The pandoc-plot executable will now process documents in parallel. This should dramatically speed up processing of large documents with lots of figures. This happens automatically through the function plotTransform.
Added a benchmarking suite.
Added defaultConfiguration so that people don't have to install the data-default package to get access to default configuration values.
Added a check for the matplotlib toolkit, preventing users from using matplotlib.pyplot.show in figures. This would halt pandoc-plot.

Release 0.4.0.1

Fixed an issue where the pandoc-plot executable could not be built outside of its git repository.

Release 0.4.0.0

Updated documentation.
Added a --full-version flag to the executable, which includes which version of pandoc/pandoc-types was used, as well as the git revision.
Added the clean command to the executable. This can be used to clean-up output files produced by pandoc-plot.
Changed the flag --write-example-config to the command write-example-config.
Added the top-level function cleanOutputDir to clean output of pandoc-plot. This is only accessible if pandoc-plot is used as a library.
Added a distinction between failure to render a figure because of a mistake, and failing to render a figure because the toolkit is not installed. pandoc-plot will give better error messages in the latter case.

Release 0.3.0.0

Added more examples.
Added MacOS binaries built via Azure pipelines.
BREAKING CHANGE: Parsing captions based on source file was not working. Captions format can be specified in the configuration file. This unfortunately changes the type signature of a few high-level functions.

Release 0.2.2.0

Fixed an issue where paths with spaces would not work (issue #2).
Added Linux binaries built via Azure pipelines.

Release 0.2.1.0

Improved documentation.

Release 0.2.0.0

Added support for gnuplot.
Added more tests for all toolkits.
Fixed an issue where the package could not be installed because a source file was not included in the cabal file.

Release 0.1.0.0

Initial release
