How to specify a value in default file from command line

[laurent-martin]

I am using the following default file:
https://github.com/IBM/aspera-cli/blob/main/docs/manual_pandoc_defaults.yaml

and pandoc is called from this makefile:
https://github.com/IBM/aspera-cli/blob/main/docs/Makefile#L31

and some pictures are referenced from this latex header:
https://github.com/IBM/aspera-cli/blob/main/docs/manual_include_in_header.tex

I use the standard template.

I have tried numerous ways to specify where to get image files from, using a variable on command line of pandoc, but never managed to make it work.

So, currently I just do not specify a path, just image file name, and images files are taken from CWD..

Any idea on how to specify the path as a variable from command line ?

did you try --resource-path?

[laurent-martin]

--resource-path did not work to specify images location.

Since I use LuaLatex as backend, finally, I did:

\graphicspath{{\directlua{tex.sprint(os.getenv('GFX_DIR'))}}}

and set env var GFX_DIR:

GFX_DIR=/path/to/folder pandoc ...
