error

Logical. Whether to throw an error if (required version of) pandoc is not available.

filter_path

Details

The following Lua filters are available from rmdfiltr. Convenience functions named after the filter are available (e.g. add_*_filter()).

replace_ampersands

Searches for citations added by pandoc-citeproc and replaces & with and in all in-text citations (e.g., as required by APA style). If lang is specified in the documents YAML front matter, the corresponding translation is used, if available. Be sure to set citeproc: no in the YAML front matter of the document and call pandoc-citeproc manually (e.g., using add_citeproc_filter). For details see vignette("replace_ampersands", package = "rmdfiltr").

wordcount

The body of the text and reference sections are counted separately. The word count for the text body does not contain, tables or images (or their captions). The filter reports the word count in the console or the R Markdown tab in 'RStudio'. For details see vignette("wordcount", package = "rmdfiltr").

Examples

add_lua_filter(NULL, "wordcount", error = FALSE)
add_wordcount_filter(NULL, error = FALSE)
add_replace_ampersands_filter(NULL, error = FALSE)
add_citeproc_filter(NULL, error = FALSE)
add_custom_filter(NULL, filter_path = "foo/bar", error = FALSE)
