Show version number in footer #340

[oneiros]

This is a very simple attempt to fix #340.

TIL (or more probably re-learned about 😬) git describe which already returns something very sensible.

In case your on a tagged version it just returns the tag name. If you are not, it will display the last tag, the number of commits since then and the abbreviated hash of the current commit. So you can see at a glance if someone uses a released version. And if not you can easily find out what state of the repo was used.

So this simply takes the output of git describe and displays it in the footer.

I think with this added, the footer includes too much to still have everything on a single line, so I opted for using some layout here:

If you have another idea how to better organize the information, please let me know.

ah nice. it gives you the last tag and the commits since then as ref with a hash. but from whats the hash? its not a commit. just curious 😄

$ git describe --tags --long
test-1-g3c31c73
_ ???

...

The "g" isn't a part of the commit.
Try looking for a commit 3c31c73 using git show 3c31c73.

🤦 😄
