Add tag to file "export-subst"

Question

Situation

We have a git workflow where all release versions fit into a branch master, and when the commit is ready for deployment, we add a tag to it and then use it git archiveto build the package for deployment.

We use the file version.txtmarked in the .gitattributesoption export-substto track which commit was used to create this archive.

Question

If I write $Format:%d$to version.txtand export a tagged commit, I will have something like (HEAD, tag, master)that written in the resulting file.

How can i use only tag?

[edit] There is a git command that already produces this:

git describe --tags HEAD

This will output:

latest_tag            #if HEAD is tagged

latest_tag-5-g03cc91b #if HEAD is not tagged,
                      #and the latest tag is 5 commits ago on commit g03cc91b

Is there any way to replace slug with this output in version.txt?
