You'd probably want --reverse, of course, since the point is to build up
the count in the same order as time flows.
So this is the working version I came up with:
git log --reverse --first-parent -m --format=%ct --numstat |
perl -lne '
if (/^\d+$/) {
if (defined $time) {
print "$time $total"
}
$time = $&;
} elsif (/^(\d+)\s+(\d+)\s/) {
$total += $1 - $2;
}
END {
# flush last entry
print "$time $total";
}
'
For my git.git repo, the final line it produces is:
1457666843 789457
which should be the final sloc-count right now. If I count the lines in
the lines in HEAD, it's close but not quite the same:
$ git ls-tree -r HEAD |
awk '{print $3}' |
xargs -n1 git cat-file blob |
wc -l
790437
I'd guess that the difference comes from a few files which are treated
as binary (and thus get "-" in their numstat output, but happen to have
newlines which cause "wc" to increment its count).
