Trouble with my configuration? `:Zrefs` and `zotref.py` throwing errors

[iGormilhit]

Hi,

I'm trying to use the zotcite plugin, with cmp_zotcite, and it's working fine for the @… completion, or with commands like :Zannotations or :Zseek, but I have trouble mainly with the :Zrefs command and the zotref.py filter (errors detailed below).

OS: archlinux. neovim: v0.10.1

My configuration is available here:

• Zotcite and cmp_zotcite plugins: https://git.milhit.ch/igor/neovim/src/branch/python-provider/lua/plugins/markdown/zotcite.lua
• cmp_zotcite completion: https://git.milhit.ch/igor/neovim/src/commit/fd295f92e46f15835b49b49c1a5c4c3fce29f5a9/lua/plugins/nvim-cmp.lua#L110
• configuration of the virtualenv that provides pyhton: https://git.milhit.ch/igor/neovim/src/branch/python-provider/lua/core/python-provider.lua

:checkhealth confirms that the python-provider is ok. I firstly tried with a 3.12 python version, with the same issues. So I tried the 3.10, but with no change.

provider.python: require("provider.python.health").check()

Python 3 provider (optional) ~
- pyenv: Path: /home/igor/.pyenv/libexec/pyenv
- pyenv: Root: /home/igor/.pyenv
- Using: g:python3_host_prog = "/home/igor/.pyenv/versions/py-nvim3.10/bin/python"
- Executable: /home/igor/.pyenv/versions/py-nvim3.10/bin/python
- Python version: 3.10.0
- pynvim version: 0.5.0
- OK Latest pynvim is installed.

Python virtualenv ~
- OK no $VIRTUAL_ENV

In the virtualenv are installed the following:

❯ pip list
Package    Version

greenlet   3.0.3
msgpack    1.0.8
pip        24.2

PyQt5-Qt5  5.15.14
PyQt5_sip  12.15.0
PyYAML     6.0.2
setuptools 57.4.0

(I have trouble with the python-poppler-qt5 installation, but that's another story.)

I have other plugins installed, of course, such as vim-pandoc and vim-pandoc-syntax, but I tried to deactivate them, with no change in my issues.

When I open a .md file, which get the pandoc filetype through vim-pandoc, if I try to use the :Zrefs command, I get:

And with the zotref.py filter:

:!pandoc filename.md --to=html --output="filename.md" -F zotref.py --citeproc

I get the following error:

Error running filter zotref.py:                                                                            
Could not find executable zotref.py

I suspect that the issue comes from the python provider, but I've followed the documentation (https://neovim.io/doc/user/provider.html#python-virtualenv).

I will of course give further information if needed.

For me the pandoc command always needs the full path unless I export the full path in .bashrc to the plugin.

Perhaps having the full path to zotref.py works?

:!pandoc filename.md --to=html --output="filename.md" -F /home/user/.local/share/nvim/zotcite/python3/zotref.py --citeproc

[iGormilhit]

@adam-coates Yes, this way it works. But the documentation says that: "The Zotcite plugin adds the directory where zotref.py is to the system $PATH." I think I will add it to the $PATH myself.

Thanks for your answer.

[adam-coates]

Great glad it works.

As with Zrefs I've never used that before now, sorry I couldn't be much help in that area.

[jalvesaq]

Thanks for reporting the bugs! :Zrefs should be fixed now.

[jalvesaq]

I can't replicate the other issue. The pandoc command works on my side.

[iGormilhit]

@jalvesaq Thanks!

How the zotcite plugin add it's path to the system $PATH?

[iGormilhit]

@jalvesaq I confirm that the 06fa405 fix resolve the :Zrefs issue. :+1:

[jalvesaq]

How the zotcite plugin add it's path to the system $PATH?

It's in the lua/zotcite/config.lua. Just seek for "PATH". I made a minor change but I don't believe it will fix the issue on your side.

[jalvesaq]

Maybe you have set the PATH yourself... To check this possibility:

cd ~/.config/nvim
grep -R PATH

You can see the PATH environment variable with this command in Neovim:

:echo $PATH
