'Lua' filters for R Markdown

A collection of 'Lua' filters that extend the functionality of R Markdown templates (e.g., count words or post-process 'pandoc-citeproc'- citations).

[

rmdfiltr provides a collection of Lua-filters that extend the functionality of R Markdown templates.

Installation

You can install the development version from this GitHub repository with:

# install.packages("remotes")
remotes::install_github("crsh/rmdfiltr")

Example

You can add a filter to any R Markdown template that accepts additional pandoc arguments.

---
title: "Word count test"
output:
  html_document:
    pandoc_args: !expr rmdfiltr::add_wordcount_filter()
---

Of course, you can also use the filters in a custom R Markdown format by adding pandoc arguments with the preprocessor function.

wordcount_html_document = function(...) {
  format <- rmarkdown::html_document(...)
  format$pre_processor <- rmdfiltr::add_wordcount_filter
  format
}

See R Markdown: The Definitive Guide for details on how to create custom formats.
