Error with Pandocomatic

[Ian Max Andolina]

pandocomatic is currently failing to start on my desktop machine. Not sure what the error message refers to

➜ pandocomatic -v

➜ ruby -v
ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin19]

➜ gem list | grep -E 'paru|pandocomatic'
pandocomatic (0.2.7.3)
paru (0.4.2)

➜ pandoc --version
pandoc 2.11.1
Compiled with pandoc-types 1.22, texmath 0.12.0.3, skylighting 0.10.0.3,
citeproc 0.1.0.3, ipynb 0.1
User data directory: /Users/ian/.local/share/pandoc or /Users/ian/.pandoc

Reverting to paru to 0.4.1.2 and pandocomatic to 0.2.7.2 and it works.

[Ian Max Andolina]

OK, if I downgrade Pandoc to V2.11.0.2 then it works:

➜ pandoc -v
pandoc 2.11.0.2
Compiled with pandoc-types 1.22, texmath 0.12.0.3, skylighting 0.10.0.2
Default user data directory: /Users/ian/.local/share/pandoc or /Users/ian/.pandoc

➜ pandocomatic -v
Pandocomatic version 0.2.7.3

v2.11.0.4 and it fails so something was changed between 2.11.0.2 and 2.11.0.4

Perhaps it was this from the changelog https://github.com/jgm/pandoc/releases/tag/2.11.0.4:

Modify --version output. Use space more efficiently and report the citeproc and ipynb versions, along with skylighting, texmath, and pandoc-types. Drop the word “default” before “user data directory.”

I can reproduce it here as well. Apparently, pandoc's version information changed and paru uses that information to figure out the default data directory.

I will fix this to match the latest version of pandoc. I'll try to look at it this afternoon.

[Ian Max Andolina]

Gosh, so helpful as always, thanks Huub!

[Huub de Beer]

Fixed the issue. You can install pandocomatic 0.2.7.4 and/or paru 0.4.2.1.
