Dear Duncan,
Thanks for chiming in. Could you explain how you set debug() on
post_processor()? I've tried adding debug(post_processor) to
rsos_article() or adding debug(post_processor) when after post_processor
was defined in the debugger. Neither work for me.
Not working for me either right now for some reason or other. What I
was doing was manually running debug(post_processor) in the debugger
after single stepping past its definition.
What does show it is running is that at that same point I can execute
post_processor <- function() stop()
and it stops.
The end of the console log looks like this:
/Applications/RStudio.app/Contents/MacOS/pandoc/pandoc +RTS -K512m -RTS
skeleton.utf8.md --to latex --from
markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash
--output skeleton.tex --template
/Library/Frameworks/R.framework/Versions/3.3/Resources/library/INBOmd/rmarkdown/templates/rsos_article/resources/template.tex
--natbib --bibliography sample.bib
Latexmk: This is Latexmk, John Collins, 19 Jan. 2017, version: 4.52c.
Error in output_format$post_processor(yaml_front_matter, utf8_input,
output_file, :
unused arguments (yaml_front_matter, utf8_input, output_file, clean,
!quiet)
Called from: output_format$post_processor(yaml_front_matter, utf8_input,
output_file,
clean, !quiet)
so we see pandoc being run, then Latexmk, then the post_processor call.
It seems a little odd that Latexmk is being run. Is that something you
are doing, or is it pandoc asking for that? If the latter, can you tell
pandoc not to do so?
I've done some debugging in rmarkdown::render. Apparently if you need
Bibtex (as your example does), it runs Latexmk before the post-processor.
I don't know if there's a way around this...

All supporting files are available within the package. The code below
should be reproducible on your machine.
remove.packages("INBOmd")
devtools::install_github("inbo/INBOmd@post_processor")
setwd(system.file("rmarkdown/templates/rsos_article/skeleton", package =
"INBOmd"))
debug(INBOmd::rsos_article)
rmarkdown::render("skeleton.Rmd")
I'm not sure you would normally have write access in that directory, so
it may not be typical of what you'd see in a user directory. I
certainly see something different when I copy the skeleton.Rmd file (and
nothing else) to my own temp directory.
The sign that post_processor() fails when the tex file still contains
\EndFirstPage resulting in the compilation error "Undefined control
sequence. l.128 \EndFirstPage"
That certainly indicates it isn't doing what you want, but it might be
running and doing something else.

I still get the error with the current version of the code. Running the
post_processor manually works.
eval(parse(
text = readLines(
"https://raw.githubusercontent.com/inbo/INBOmd/post_processor/R/rsos_article.R";
)[72:92]
))
post_processor(output_file = "skeleton.tex")
system("pdflatex skeleton.tex")

Dear all,
I'm trying to write a post_processor() for a custom rmarkdown
format. The
goal of the post_processor() is to modify the latex file before
it is
compiled. For some reason the post_processor() is not run. The
post_processor() does work when I run it manually on the tex file.
Any suggestions on what I'm doing wrong? Below is the relevant
snippet of
the code. The full code is available at
https://github.com/inbo/INBOmd/blob/post_processor/R/rsos_article.R
<https://github.com/inbo/INBOmd/blob/post_processor/R/rsos_article.R>
https://github.com/inbo/INBOmd/blob/post_processor/inst/rmarkdown/templates/rsos_article/skeleton/skeleton.Rmd
<https://github.com/inbo/INBOmd/blob/post_processor/inst/rmarkdown/templates/rsos_article/skeleton/skeleton.Rmd>
is an Rmd is a MWE that fails compile because the
post_processor() is not
run.
I installed it and tried running it using
debug(INBOmd::rsos_article)
rmarkdown::render("skeleton.Rmd")
then after post_processor was defined, I set it to debug as well,
and could see that the post_processor was being run.
I didn't get useful output, because the LaTeXing failed (I don't
have the rsos.cls), but perhaps you've already fixed this problem,
or perhaps it is intermittent?
