How to use the command "git-summary" (with examples)

1: Display data about a Git repository

git summary

Motivation:

The git summary command provides a quick overview of a Git repository, including the number of commits, contributors, and files.

Explanation:

Simply running git summary without any additional arguments will display the general information about the repository, such as the total number of commits, authors, and files.

Example output:

Commits: 1000
Authors: 10
Files: 50

git summary commit|branch_name|tag_name

Motivation:

It can be useful to see the data about a Git repository since a specific commit, branch, or tag. This feature becomes handy when you want to analyze the changes made after a certain point in your Git history.

Explanation:

By providing a commit, branch, or tag name to the git summary command, you can see the repository data from that specific point in time until the latest commit.

Example output:

Commits: 500
Authors: 8
Files: 40

git summary --dedup-by-email

Motivation:

In some cases, different email addresses can be associated with the same contributor, leading to separate statistics for each email. This option allows merging committers with different email addresses into a single statistic for each author.

Explanation:

When running git summary with the --dedup-by-email flag, the command combines the contributions of authors with different emails under a single author, resulting in aggregated statistics for each person.

Example output:

Commits: 800
Authors: 10
Files: 50

git summary --line

Motivation:

Tracking the number of lines modified by each contributor can be helpful in understanding individual contributions and overall codebase changes over time.

Explanation:

The --line option generates a summary that includes the number of lines added, deleted, and modified by each contributor. This provides insights into the level of involvement and impact of each author.

Example output:

Author 1:
  Lines added: 500
  Lines deleted: 200
  Lines modified: 700

Author 2:
  Lines added: 300
  Lines deleted: 150
  Lines modified: 450
