I’m wondering how do you deal with displaying release revision number when pushing live new versions of your app?
You can use $Rev$ in a file to get latest revision, but only after you update the file.
What if I want to update a string in one file every time I change any file in the repository/directory?
Is there a way?
Did you try to use hooks? They work on server-side only but may do the trick. Otherwise I would just call a script do update the revision if the keywords aren’t suitable for you.
