git-also v1.1.0

git-also

For a file in your git repository, prints other files that are most often committed together.

This is a demo of git-also applied on three.js library:

> src/core/Object3D.js most often committed with:

# together	Similarity	Name
        51	      0.22	src/core/Geometry.js
        48	      0.21	src/renderers/WebGLRenderer.js
        45	      0.19	build/Three.js
        43	      0.18	src/materials/Material.js
        36	      0.15	build/custom/ThreeWebGL.js
        36	      0.15	src/cameras/Camera.js
        35	      0.15	build/custom/ThreeCanvas.js
        34	      0.15	build/custom/ThreeSVG.js
        34	      0.15	build/custom/ThreeDOM.js
        32	      0.14	src/core/BufferGeometry.js

This means that file Object3D.js is most often committed with Geometry.js - they both appear together in 51 commits! By looking at this output you can immediately see core pieces of three.js.

The Similarity column shows Jaccard index of two files.

usage

Install the package with npm:

npm install -g git-also

Run it from command line inside your git repository:

git also <file>

If you run it without arguments it prints help:

  Usage: git-also [options] <file>

  For a <file> in your git repository prints other files that are most often committed together

  Options:

    -h, --help       output usage information
    -V, --version    output the version number
    -c, --count <n>  Print top N other files. N is 10 by default

motivation

Files are often committed together when developers improve code or add new features. This information could serve as a hint when you are exploring new code:

• What are related file to this file?
• Where else should I look when I fix bugs in this file?
