Include pandoc-crossref

[colindean]

Is your feature request related to a problem? Please describe.

My build uses pandoc-crossref, which I've installed locally. It's not available in pandocker.

Describe the solution you'd like

pandoc-crossref could be included in pandocker.

Describe alternatives you've considered

I could build and ship my own fork.

It looks like there's https://github.com/kiwi0fruit/py-pandoc-crossref available in pypi!

I tried adding py-pandoc-crossref to requirements.txt

diff --git a/requirements.txt b/requirements.txt
index cdb8c5f..dc5643a 100644

but I'm getting this error:

…is this a Python2/Python3 thing?

[colindean]

My inexperience with the Python ecosystem is showing. I use make warm-cache before make build and that succeeded. When I clear the cache and run make build, the pip3 inside the container can't find py-pandoc-crossref:

Collecting py-pandoc-crossref==0.3.6.0 (from -r requirements.txt (line 14))
  Could not find a version that satisfies the requirement py-pandoc-crossref==0.3.6.0 (from -r requirements.txt (line 14)) (from versions: )
No matching distribution found for py-pandoc-crossref==0.3.6.0 (from -r requirements.txt (line 14))

[colindean]

I tried an older version 0.3.5.0.2 – 0.3.6.0 just came out hours ago? – as well as upgrading pip before running the install from requirements.txt and it still can't find the package.

[colindean]

I think I figured it out. py-pandoc-crossref requires python 3.6+ and Debian stretch includes python 3.5.

…Interested in using a new version of Debian?

Hi @colindean !

We planned to upgrade to debian buster and made a failed attempt this summer
https://github.com/dalibo/pandocker/pull/100

Unfortunatelly the texlive distibution system is a mess on debian buster... We have to figure how we can make it work....

My understanding is that pandoc-crossref is written in Haskell so I don't see why the python3.6 should be required. I'll try to make it work without py-pandoc-crossref...

Upgrading to buster breaks tlmgr

tlmgr: Remote repository is newer than local (2018 < 2019)
Cross release updates are only supported with
  update-tlmgr-latest(.sh/.exe) --update
Please see https://tug.org/texlive/upgrade.html for details.

https://tug.org/texlive/upgrade.html has instructions but https://tex.stackexchange.com/questions/495054/tlmgr-remote-repository-is-newer-than-local-2018-2019 advises:

To add to Ralf's correct answer, here an explanation why tlmgr gives this error: Debian/buster comes with TL2018, and thus refuses to work with the 2019 repositories, even in self mode. I agree that this is an inconvenience, and I will see whether I remove this check in self mode, either in upstream tlmgr, or only in the Debian packages.

For now there is no good solution but either stick with Debian's packages, which are at the status of about January 2019, or install upstream TUG's TL and ignore the Debian one.

The package texlive-fonts-extra includes ~some~ all fonts that are installed by tlmgr:

• [X] ly1
• [X] inconsolata
• [X] sourcesanspro
• [X] sourcecodepro
• [X] mweights
• [X] noto

[colindean]

The chief problem of installing texlife-font-extra is that it's another 1,101,775.0 kiB on disk. That's probably excessive.

Abandoning the Python approach and going to the release binaries.
