What's Goslings

Goslings visualizes a Git repository.

A Git repository consists of objects, references, and an index.

• Object
  • Blob: Represents a file, and contains the entire contents of the file.
  • Tree: Represents a directory, and contains pointers to other trees and blobs.
  • Commit: Represents a commit, and contains pointers to the parent commits and a pointer to a tree which represents the project's root directory.
  • Annotated Tag: Represents an annotation of a tag, and contains a pointer to a commit.
• Reference
  • Branch: A pointer to a commit.
  • Tag: A pointer to a commit or a tag object.
  • Symbolic Reference: A pointer to a branch or commit.
• Index: A structure containing paths to files and pointers to blobs.

Understanding this repository architecture helps you to master Git. Goslings was created as a tool to learn the architecture.

Download

You can download Goslings from GitHub Releases

Build

1. Install Git and JDK 8+.
2. Download the project by git clone --recursive https://github.com/kaitoy/goslings.git.
3. In the project root directory, run ./gradlew build.

How to Use

JRE 8+ is required to run Goslings server.

Run java -jar goslings/goslings-server/build/libs/goslings-server-0.0.1.jar --server.port=80 to start Goslings server. After the startup completes, open http://localhost by a Web browser. You will see Goslings GUI like below:

In the GUI, enter the path to or the URL of a Git repository (e.g. C:\tmp\goslings\.git, /tmp/goslings/.git, https://github.com/kaitoy/goslings.git, etc.) and press the Browse button. Then, Goslings server creates a symlink (if local) or a clone (if remote) of the repository into the working directory goslings in the tmp directory which java.io.tmpdir points to, and shows the Git objects and references like below:

• Legend:

  • Pink Circle : Commit
  • Green Triangle: Tree
  • Purple Box : Blob
  • Red Diamond : Tag Object
  • Blue Box : (Symbolic) Reference
  • Green Box : Index

• Operations

  • Use your mouse wheel to zoom in and out.
  • Drag and drop an object, a reference, or the index to move it.
  • Drag and drop the background to slide the view.
  • Single click on an object, a reference, or the index shows its contents.
  • And double click on a commit or a tree shows trees and blobs under it.

• Configurations

  • com.github.kaitoy.goslings.server.reposDir: Set this property to change the path of the working directory.
  • com.github.kaitoy.goslings.server.uriPrefix: If this property is set, the Goslings server returns an error for a repository URI which doesn't start with the value of the property.
