Caller must provide a
file_scope
function used to break apart a markdown file to be passed to pandoc into multiple files. This in turn enables the use of pandoc's--file-scope
(https://pandoc.org/MANUAL.html#option--file-scope), which in turn resolves duplicate numeric footnote id's across files.In the short term this will be used by bookdown to enable correct handling of duplicate numbered footnotes across chapters.
Note that if
render()
handled multiple input files by passing them all to pandoc, we could makefile_scope
a boolean or a function (where the boolean would result in just passing--file-scope
without any splitting). However, for multiple inputsrender()
calls itself recursively (meaning that pandoc always gets a single Rmd anyway, so--file-scope
would have no meaning).
