git log sum example

git_log_sum_ex

% git log --stat --author=dameninngenn --since="2011-07-15" --before="2011-08-15" --no-merges | grep 'files changed' | awk '{ins += $4}{del += $6} END{print "total: "ins"insertions(+) "del"deletions(-)"}'

> total: 3385insertions(+) 1089deletions(-)

Great command except when there are commits with only deletions, then the parameter order is messed up and deletions count for insertions.

% echo "4 files changed, 202 deletions(-)" | awk '{ins += $4}{del += $6} END{print "total: "ins"insertions(+) "del"deletions(-)"}'
total: 202insertions(+) 0deletions(-)

I use sed to add , 0 insertions(+) when necessary and then the parameter order for awk is restored.

% echo " 4 files changed, 202 deletions(-)" | sed -E 's/d, ([[:digit:]]+)/d, 0 insertions(+), \1/g'      
 4 files changed, 0 insertions(+), 202 deletions(-)                                                                             

TL;DR: The fixed command would be:

% git log --stat --author=dameninngenn --since="2011-07-15" --before="2011-08-15" --no-merges | grep 'files changed' | sed -E 's/d, ([[:digit:]]+)/d, 0 insertions(+), \1/g' | awk '{ins += $4}{del += $6} END{print "total: "ins"insertions(+) "del"deletions(-)"}'

Bonus:

per authors in all branches

git log --all --since="11 days ago" --no-merges --pretty=format:%an | sort | uniq | xargs -I% -L1 bash -c 'echo $0; git log --all --stat --author="$0" --since="11 days ago" --no-merges | grep "files changed" | sed -E "s/d, ([[:digit:]]+) d/d, 0 insertions(+), \1 d/g" | awk '\''{ins += $4}{del += $6} END{print "total: "ins"insertions(+) "del"deletions(-)"}'\'';' "%"

Example output:

  Tobi Myers
  total: 409insertions(+) 76deletions(-)
  Rangid Kouthrapalli
  total: 1047insertions(+) 1165deletions(-)
  Roger Seifert
  total: 1013insertions(+) 2058deletions(-)
  Vanessa Lambert
  total: 71insertions(+) 34deletions(-)

Thank you for your opinion.
It seems great! Thanks!
