This software does statistical analysis of git and github-based repositories. It will accept a list of repositories to analyse (with credentials if necessary) and talk both to github and check out code to do analysis.

Logic

While some of those statistics can be obtained from github or git, it is not very simple and not really team oriented. This software allows you to understand trends happening

Input data and formats

Configuration files must be placed in analyser/input folder. Following files are allowed:

1. repos.json This expects you to define following entries:

[
   {
       "server": "github.com",
       "api": "api.github.com/graphql",
       "owner": "organization",
       "name": "org-repo",
       "token":"<token_with_repo_access>",
       "protocol": "https",
       "ignore_list": [ "pom.xml", "yarn.lock", "package.json", "package-lock.json" ], //files in your repo to ignore during analysis
       "long_living_branches": ["develop","master"], //long living branches of your repo, will never be marked as stale, they are also counted as a separate data point when analysing PR statistics
       "main_branches": ["production"], //main branches of your repo, will never be marked as stale 
       "stale_branch_after": 30 //days of no activity after which branch is set to stale
   },
     {
       "server": "github.com",
       "api": "api.github.com/graphql",
       "owner": "user",
       "name": "user-repo",
       "token":"<token_with_repo_access>",
       "protocol": "https",
       "ignore_list": [ "pom.xml", "yarn.lock", "package.json", "package-lock.json" ],
       "long_living_branches": ["develop","master"],
       "main_branches": ["production"],
       "stale_branch_after": 30
   }
]

2. teams.json

[
    {
      "name": "Team1", 
      "color": "#1A8FE3", //color to be used when drawing graphs
      "members": [
        {
          "name": "John",
          "email": "john@mail.com",
          "login": "johnny"
        },
        {
          "name": "Jane",
          "email": "jane@gmail.com",
          "login": "jane-coder"
        }
      ]
    }  
]

3. mailmap file in .mailmap format that will be used as default mailmap if no mailmap file is available in your repository. See https://git-scm.com/docs/gitmailmap. Optional. If your repository contains its own .mailmap file, it will be used. If your repository does not have .mailmap file, but you provide mailmap file in input folder, this will be used. Not providing .mailmap file may result in confusing results, as different user emails will be recognized as different users. See linked document. Here file name must be WITHOUT leading dot

Folder structure

data_loader python sources for analyser input configuration files go here input_samples self explanatory output results of analyser will go here presenter python sources for report generation. If you want to implement your own, feel free to use data from output folder.
reports HTML reports generated by presenter go here

Running

Using analyser as root folder, start analyser.py script. It will check out the repository into repos folder and run analysis using both git and github capabilities.

Once the analysis is completed, run presenter.py script to generate html reports.

If you don't want to use defualt reports, feel free to use extracted data placed in output folder to create your own reports.

Using with docker

It is recommended to mount both input and reports folders into your image for easy configuration and report storage.

Known issues and quirks

To perform the analysis, this software must check out the repository being analysed. At the moment the repos folder, where repositories to analyse are placed, is not being cleaned up. If you want to analyse multiple large repositories, be mindful of available space.

So how does it look like?

See it for yourself, sample_report is there for you.

It contains analysis executed on cypress repo with two main committers added in a sample team.
