Are you sure that you want to read in the output_file in
text <- readLines(output_file, warn = FALSE)?

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/inst/
rmarkdown/templates/rsos_article/skeleton/skeleton.Rmd
is an Rmd is a MWE that fails compile because the post_processor() is not
run.
Best regards,
Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.
