## Install recent pandoc version, required by rmarkdown
# - see https://github.com/rstudio/rmarkdown/blob/master/PANDOC.md
# - https://pandoc.org/installing.html#linux
# We should use the same version as in rocker/rstudio:<R_VER>
#   docker run --rm rocker/rstudio:<R_VER> /usr/lib/rstudio-server/bin/pandoc/pandoc -v

## Install TinyTeX as LaTeX installation
COPY docker/install_tinytex.sh .
# - Use a version-stable tlnet archive CTAN repo from texlive.info
#   - here we consider the frozen TeXLive 2016 snapshot, corresponding to the TeXLive release
#     shipped as texlive-* in Debian stretch (base image for the rocker/verse currently used)
#   - note that https was not supported in TeXLive 2016 for the CTAN repository
ENV CTAN_REPO=http://www.texlive.info/tlnet-archive/2017/04/13/tlnet
# - It is important to also install all required LaTeX packages when building the image
RUN sh install_tinytex.sh fancyhdr
## Script for re-installation of TinyTeX in the running container
#  - needed if at a certain point the "Remote repository is newer than local",
#    for non-version-stable TinyTeX installations
#  - this also (re-)executes (and therefore depends on) install_tinytex.sh
COPY docker/reinstall_tinytex.sh .

## Install major fixed R dependencies
#  - they will always be needed and we want them in a dedicated layer,
#    as opposed to getting them dynamically via `remotes::install_local()`

  shiny \
  dplyr \

# temporary location of the SmaRP source package in the image
