Pandoc conversion to pdf not working on heroku

QUESTION

Pandoc conversion to pdf not working on heroku

Asked 2021-Jan-25 at 19:29

I have a ruby on rails app that uses pandoc-ruby to convert markdown files into pdf. The pandoc-ruby requires pandoc installation. To successfully convert to pdf, pdflatex needs to be present as well. Locally (tested on Mac and Ubuntu 18.04) everything is working if pandoc, texlive-latex-recommended and texlive-fonts-recommended packages are installed. Things get a little bit tricky when deploying to heroku. To install all the packages on heroku I've used the Aptfile approach and I have not been able to solve this.

Approach 1: Aptfile

I've specified this Aptfile:

After quite a bit of trial and error, I have found a solution that works.

As @mb21 mentioned, Docker image would probably be the best option long term. Docker images are supported on Heroku. However, I wanted to avoid dockerizing the whole application to solve this issue.

After finding a TeX Live buildpack for Heroku that supports adding custom TeX Live packages (one example of such buildpack), the error on conversion was ! LaTeX Error: File 'xcolor.sty' not found.

I used tlmgr to get some info on the missing file. Running tlmgr search --global --file xcolor.sty does the trick and reveals that there is a package called xcolor. After installing that we come to the next error, and the next, and the next. In the end I ended up installing 2 collections that are small enough for Heroku (mind the 500MB slug size limit) and contain everything pandoc needs for a successful conversion. Those 2 are collection-fontsrecommended and collection-latexrecommended.

Adding a texlive.packages file to the root of the application does the trick. It is recognized by the buildpack and it installs all the specified packages for you using tlmgr.
