latexdiff: Produce a diff of two files using latexdiff

In latexdiffr: Diff 'rmarkdown' Files Using the 'latexdiff' Utility

Description

latexdiff() uses the external utility latexdiff to create a PDF file showing differences between two Rmd, Rnw or TeX files.

Usage

latexdiff(
  path1,
  path2,
  output = "diff",
  open = interactive(),
  clean = TRUE,
  quiet = TRUE,
  output_format = NULL,
  ld_opts = "--replace-context2cmd=\"none\""
)

Arguments

path1	Path to the first file.
path2	Path to the second file.
output	File name of the output, without the .tex extension.
open	Logical. Automatically open the resulting PDF?
clean	Logical. Clean up intermediate TeX files?
quiet	Logical. Suppress printing? Passed to render and knit, and hides standard error of latexdiff itself.
output_format	An rmarkdown output format for Rmd files, probably rmarkdown::latex_document(). The default uses the options defined in the Rmd files. YAML front matter.
ld_opts	Character vector of options to pass to latexdiff. The default avoids some problems with Rmd files.

Details

File types are determined by extension,which should be one of .tex, .Rmd or .rnw. Rmd files are processed by rmarkdown::render(). Rnw files are processed by knitr::knit().

You will need the latexdiff utility installed on your system:

# on MacOS:
brew install latexdiff

# on Linux:
sudo apt install latexdiff

latexdiff is not perfect. Some changes will confuse it. In particular:

• If input and output files are in different directories, the "diff.tex" file may have incorrect paths for e.g. included figures. latexdiff will add the --flatten option in this case, but things still are not guaranteed to work.

Value

Invisible NULL.

Examples

## Not run: 
latexdiff("file1.Rmd", "file2.Rmd")

## End(Not run)
