pandoc -v
pandoc 2.3.1
Compiled with pandoc-types 1.17.5.1, texmath 0.11.1.1, skylighting 0.7.3

pandoc -h says that there is `-V` and `--varaible KEY[:VALUE]` flag. I want 
to include some value at rendering time (document version). So I did this:

pandoc  --variable gitcommit:xxxxxyyy -o markdowndoc.pdf markdowdoc.md

---
title: Test Variables
output: pdf_document
header-includes:
    - \usepackage{hyperref}
    - \usepackage{datetime}
    - \usepackage{fancyhdr}
    - \pagestyle{fancy}
    - \fancyhead[LE,LO]{}
    - \fancyfoot[CO,CE]{Template Version \pdfdate| Git Commit:$gitcommit$}
    - \fancyfoot[LE,RO]{\thepage}
---

Variable value, gitcommit: $gitcommit$


This however did not result in expected value in the finale PDF document. 
So is it possible at all to do this kind of thing at the moment?

Variable are only resolved in the templates
themselves, not in material (like header-includes)
that will itself be put in templates.

For your purposes you'll have to use a custom
template.

Thanks for your comment, John. For now I chose to use a bash script which 
runs a `sed` command before rendering with pandoc, and it works fine.
