%description
The document converter 'pandoc' <https://pandoc.org/> is widely used in
the R community. One feature of 'pandoc' is that it can produce and
consume JSON-formatted abstract syntax trees (AST). This allows to
transform a given source document into JSON-formatted AST, alter it by so
called filters and pass the altered JSON-formatted AST back to 'pandoc'.
This package provides functions which allow to write such filters in
native R code. Although this package is inspired by the Python package
'pandocfilters' <https://github.com/jgm/pandocfilters/>, it provides
additional convenience functions which make it simple to use the
'pandocfilters' package as a report generator. Since 'pandocfilters'
inherits most of it's functionality from 'pandoc' it can create documents
in many formats (for more information see <https://pandoc.org/>) but is
also bound to the same limitations as 'pandoc'.
