Include Git Hash in PDF

Include Git Hash in PDF

['Jan Ulrich Hasecke' via pandoc-discuss]

Hi all,

I am lost.

How can I insert the commit hash from git in the output file?

I tried to evaluate "git rev-parse HEAD" in a build script and hand over 
the result to the build process by setting a custom variable to the hash 
string via --variable hash=${git rev-parse HEAD}. In my template I have 
$hash$

I stored the hash in a file and tried to include it with -B, though this 
would not be a good solution if it worked at all.

I guess this is quite a common requirement but I failed to find the 
solution with Google & Co.

Any hints
juh

The syntax for including command output in a shell command line is
$(cmd), not ${cmd}. ${cmd} expands to the value of the shell variable
cmd instead of executing cmd. Your command line should thus look like

$ pandoc ... --variable "hash=$(git rev-parse HEAD)"

Do you have $include-before$ somewhere in your template, if not then
pandoc doesn't know where to include the contents of the file.
