Visulog

Tool for analysis and visualization of git logs

Presentation

Visulog a tool for analyzing contributions from the members of a team working a a same given project hosted on a git repository. Its goal is to assist teachers for individual grading of students working as a team.

This tool can:

• compute a couple of relevant indicators such as:
  • number of lines or characters added/deleted/changed
  • number of commits
  • number of merge commits
• analyze the variations of these indicators in time: for instance sum then in a week, compute a daily average or an average in a sliding window, ...
• visualize the indicators as charts (histograms, pie charts, etc.) embedded in a generated web page.

Already existing similar tools

• gitstats

Technical means

• The charts are generated by a third party library (maybe a Java library generating pictures, or a javascript library which dynamically interprets the data).
• The data to analyze can be obtained using calls to the git CLI. For instance "git log", "git diff --numstat", and so on.

Architecture

Visulog contains the following modules:

• a git log parser
• a generator of numerical series (for the indicators mentioned above)
• a generator of web pages
• a command line program that calls the other modules using the provided command line parameters
