What do the git statistics mean?

Question

I probably don't know how to search for this, but can't find what the git stats that are shown when you do a git pull or a "git show --stat 947a403" (--stat is not in the manpage) It's supposed to be line ins/del but they don't really match.

What are these numbers and the + and - ? Is this something like a levenshtein distance?

Answer 1

These show the files changed and the lines added and removed in each. In your example, 3 files changed, and in ek.face.js, one line was added, one line was removed.

Answer 2

TODO ... 3 additions 1 deletion
htdocs/main/js/ek.balcony.js ... 7 additions 3 deletions
htdocs/main/js/ek.face.js ... 1 addition 1 deletion

As for the number... I'm not 100% sure. It may be a line-count as to how many lines were added/deleted.
