A multi-repo Git query tool

Walrus

A multi-repo Git query tool

Purpose

I spend a fair amount of time tracking down the what and when of my daily activities. Usually this searching spans many (10+) repositories which means the task is boring and tedious. Walrus tool aims to automate the discovery of git commits based on date, author, and other criteria.

Goals

We don't want to reinvent libgit2sharp, we just want a simple query interface specific to commit messages. We don't care about diffs, code content, or even the change sets. For this reason, Gitbase was found to be entirely overkill even though it is pretty rad. It is a fantastic tool and I do make use of it but managing it is kind of a pain. For this reason, the overarching goal of this project is simplicity with the ability to opt-in to complexity when needed.

Getting Started

This utility should be used as a dotnet tool. See tools/install_as_tool.ps1 for how to build and install Walrus on your system.

To query multiple roots or query from any location, you will need to setup a simple JSON config file. This can be specified as an env WALRUS_CONFIG_FILE or a file named walrus.json placed in your current working directory. The contents should look something like this is:

{
  "DirectoryScanDepth": 3,
  "RepositoryRoots": [
    "H:\\code",
  ],
  "AuthorAliases": {
	  "illyum": [
		  "[e-mail]",
		  "[e-mail]"
	  ]
  }
}

If you like to keep a flat code directories then you can set DirectoryScanDepth to a smaller value. This value affects performance so chose carefully.

Examples

These examples assume you have installed Walrus.CLI as a dotnet tool.

Show the active configuration

walrusc show config

Print a list of all repositories

walrusc show repos

Use the default scan depth and search for repositories relative to your current directory. No config file needed!

walrusc query --current-directory

Count commits between March 2 and Jun 2 of 2021. This includes all authors on the currently checked out branch in each repository

walrusc query --after "Mar 2 2021" --before "Jun 2 2021"

Show all commits on all branches since last week (default if --after is not specified) and restrict to a single author

walrusc query --all-branches --author-email [e-mail]

Print a commit summary table organized by repo and date to the console

walrusc query --author-email [e-mail] --group-by repo
