Situation
We have a git workflow, where all release versions are stacked on the master branch, and when a commit is ready for deployment, we add a tag to it, then use git archive to build a bundle to be deployed.
We use a version.txt file, marked in .gitattributes with the option export-subst, to keep track of which commit was used to build a given archive.
Question
If I write $Format:%d$ in version.txt, and export a tagged commit, I will have something like (HEAD, tag, master) written in the resulting file.
How can I have the tag alone ?
[edit] There is a git command which already produces that :
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 some way to have a slug replaced with this output in version.txt ?

gitattributes file allows you to specify the files and paths attributes that should be used by git when performing git actions, such as git commit , etc. In other words git automatically saves the file according to the attributes specified, every time a file is created or saved.
Step 1: Go to your git bash. and then to the repo you want to extract or export. Here, we are going to export this repo named 'Ada August-a Challenge' and it's main branch. Step 2: Now export it to your preferred format and location, here we will export it to the same location in .
Using attributes, you can do things like specify separate merge strategies for individual files or directories in your project, tell Git how to diff non-text files, or have Git filter content before you check it into or out of Git.
Git archive is a helpful utility for creating distributable packages of git repositories. Git archive can target specific refs of a repository and only package the contents of that ref. Git archive has several output formats that can utilize added compression.
You could use a content filter driver which would on git checkout automatically do the exact change you want.
(From Pro Git book 7.2 Customizing Git - Git Attributes)
You declare in a .gitattributes file a smudge script which will do the substitution for a special marker (that you want to be replaced with git describe --tags HEAD), without touching the other markers to be modified by export-subst on git archive.
Then you call git archive, which should (not tested) replace the rest.
