LineLord

The Barbarian's Guide to Git Repository Conquest

“What is best in code? To crush the bugs, see them driven from your repository, and to hear the lamentations of their stack traces!” — Gorvek of Bonereach

Every number below was read by LineLord 1.0.0-rc.3 from a generated demo repository, at the revision 26104a6e. Nothing on this page is analysed when you load it — LineLord is a terminal tool, and this is what it reports.

Looking past 1 commit named in .git-blame-ignore-revs, so their lines are credited to whoever wrote them rather than to whoever reformatted them.

Repository Overview

10 of 14 tracked files were read. The rest were set aside: 1 binary, 2 generated, 1 over the threshold. 205 lines still stand, held by 4 warriors.

Brutal Barbarian Rankings

A ranking by conquest rather than by volume. Every metric counts lines still alive in the analysed revision.

Code Longevity

The codebase is 2y 1m old at the middle, 1% of it last touched within ninety days. Oldest line still standing: Makefile:1 — 4y 0m old.

The history was walked over 11 revisions, which is where the half-life comes from: how long until half of a month's work is gone. A dash means the history saw that code only once and knows nothing either way — which is not the same as short-lived.

In the terminal o changes the order: median, mean and lines, and half-life and survival once the history is walked.

One Warrior, Many Names

An email address is an identity, and nothing is inferred from names. Where two contributors look like one person LineLord says so and nothing was merged — both addresses keep their own place in the ranking, because two entries for one warrior should be a thing you decide about rather than a thing you have to notice.

The merge screen offers these one at a time, and taking one writes it into .mailmap; --write-mailmap writes them all at once. They are guesses, and the guessing is wrong often enough to matter, so read them before committing them: 

Gorvek of Bonereach <gorvek@bonereach.realm> <gorvek@kell.realm>

So are they merged? Not by LineLord, which counts addresses before you write the file and after. But .mailmap is git's own file, and git blame applies it before LineLord sees a single line — so from the next run the two are one warrior, with one row and one share, because git says they are the same person rather than because a heuristic guessed it. The decision lives in a file you wrote, where git shortlog reads it too, and a wrong guess is a line to delete rather than a verdict to argue with.
