GitProject health

This project includes a model, an importer, and some visulization to evaluate the health of a GitLab or GitHub group.

Installation

Download a Moose image.

In the Moose image, in a playground (Ctrl+O, Ctrl+W), perform:

Metacello new
  repository: 'github://moosetechnology/GitProjectHealth:main/src';
  baseline: 'GitLabHealth';
  onConflict: [ :ex | ex useLoaded ];
  onUpgrade: [ :ex | ex useIncoming ];
  onDowngrade: [ :ex | ex useLoaded ];
  load

Usages

Import

Group import: GitLab

In a playground (Ctrl+O, Ctrl+W).

glhModel := GLHModel new.

glhApi := GLHApi new
    privateToken: '<Your private token>';
    baseAPIUrl:'https://gitlab.myPrivateHost.com/api/v4';
    yourself.

glhImporter := GLHModelImporter new
    glhApi: glhApi;
    glhModel: glhModel.


"137 is the ID of the a Group, you can find the number in the webpage of every project and group"
glhImporter importGroup: 137.

Group import: GitHub

In a playground (Ctrl+O, Ctrl+W).

glhModel := GLHModel new.

githubImporter := GHModelImporter new glhModel: glhModel; privateToken: '<my private token>'; yourself.

githubImporter importGroup: 'moosetechnology'.

More commits extracted

GitLab API only

You might want to gather more commits for a specific repository. To do so in GitLab, we added the following API

myProject := ((glhModel allWithType: GLHProject) select: [ :project | project name = '<my projectName>' ]) anyOne.

glhImporter importCommitsOf: myProject withStats: true until: '2023-01-01' asDate.

Visualize

To visualize the group "health"

dritGroup := (glhModel allWithType: GLHGroup) detect: [ :group | group id = 137 ].
canvas := (GLHGroupVisualization new forGroup: dritGroup).
canvas open.

Export

To export the visualization as a svg image

dritGroup := (glhModel allWithType: GLHGroup) detect: [ :group | group id = 137 ].
canvas := (GLHGroupVisualization new forGroup: dritGroup).
canvas open.

canvas svgExporter
  withoutFixedShapes;
  fileName: 'drit-group-health';
  export.

Running metrics with docker

"This example set up and run a GitProjectHealth metrics over two period of time of a given set of users and their projects.
It ouputs a csv files containing : churn code, commits frequencies, code addition and deletion, comments added (e.g. // # /**/ ), avg delay before first churn and merge request duration.
