Vars file as argument?

[DigitalTravelDuck]

Is it possible to give the vars.yaml file as an argument with - - filter pandoc-mustache? or any other way to use one markdown file and 2 different vars file to generate 2 different pdf's out of it? would be great.

pandoc-mustache only accepts pointers to the variables file from a YAML metadata block in the document. But you could customize the metadata block from the command line. Here's a verbose example:

document.md:

The richest American men live {{diff_le_richpoor_men}} years longer than the poorest men,
while the richest American women live {{diff_le_richpoor_women}} years longer than the poorest women.

metadata_one.yaml:

---
mustache: ./le_gaps.yaml
---

metadata_two.yaml:

---
mustache: ./animals.yaml
---

le_gaps.yaml:

diff_le_richpoor_men: "14.6"
diff_le_richpoor_women: "10.1"

animals.yaml:

diff_le_richpoor_men: "zebra"
diff_le_richpoor_women: "giraffe"

Then you can generate two different outputs with:

• pandoc metadata_one.yaml document.md --filter pandoc-mustache
• pandoc metadata_two.yaml document.md --filter pandoc-mustache

With a carefully constructed shell command, you could also embed the metadata block in metadata_one/metadata_two directly into the command to eliminate the need for those two extra files.
