## Overview
Gitblit is an open-source, integrated pure Java stack for managing, viewing, and serving [Git][git] repositories.
Its designed primarily as a tool for small workgroups who want to host [Git][git] repositories on a Windows machine.  Having said that, it works equally well on any standard Linux distribution.
 
### Current Release

[%VERSION%](http://gitblit.com/%DISTRIBUTION%) based on [%JGIT%][jgit]   (*%BUILDDATE%*)

sources @ [Github][gitbltsrc]

### Design Principles
1. [Keep It Simple, Stupid](http://en.wikipedia.org/wiki/KISS_principle)
2. Offer useful features for serving Git repositories.  If feature is complex, refer to #1.
3. All dependencies must be retrievable from a publicly accessible [Maven](http://maven.apache.org) repository.<br/>This is to ensure authenticity of dependencies and to keep the Gitblit distribution svelte.  

### Features
- Out-of-the-box integrated stack requiring minimal configuration
- JGit SmartHTTP servlet
- Browser and git client authentication
- Four repository access control configurations and a Read-Only flag
    <ul class='noBullets'>
    <li>![anonymous](blank.png) *Anonymous View, Clone & Push*</li>
    <li>![push](lock_go_16x16.png) *Authenticated Push*</li>
    <li>![clone](lock_pull_16x16.png) *Authenticated Clone & Push*</li>
    <li>![view](shield_16x16.png) *Authenticated View, Clone & Push*</li>
    <li>![freeze](cold_16x16.png) Freeze repository (i.e. deny push, make read-only)
    </ul>
- Gitweb inspired UI
- Administrators may create, edit, rename, or delete repositories through the web UI
- Administrators may create, edit, rename, or delete users through the web UI
- Repository Owners may edit repositories through the web UI
- Automatically generates a self-signed certificate for https communications
- Dates can optionally be displayed using the browser's reported timezone
- Author and Committer email address display can be controlled
- Dynamic zip downloads feature
- Markdown view support
- Syntax highlighting
- Customizable regular expression handling for commit messages
- Single text file for server configuration
- Single text file for users configuration
- Simple repository stats and activity graph (uses Google Charts)
- Optional utility pages
    <ul class='noBullets'>
    <li>![docs](book_16x16.png) Docs page which enumerates all Markdown files within a repository</li>
    <li>![tickets](bug_16x16.png) Ticgit ticket pages *(based on last MIT release bf57b032 2009-01-27)*</li>
    </ul>

### Limitations
- HTTP/HTTPS are the only supported protocols
- Access controls are not path-based, they are repository-based
- Only Administrators can create, rename or delete repositories
- Gitblit is an integrated, full-stack solution.  There is no WAR build at this time.

### Todo List
- Review spots where Gitblit can cache data instead of abusing the disk
    - stats
    - users.properties access
    - available repositories
    - etc
- Code documentation
- Unit testing

### Idea List
- Ticgit activity/timeline
- Ticgit query feature with paging support
- Ticgit ticket change history
- View images on Blob page
- View other binary files on Blob page
- Markdown editing feature
- Blame (waiting for the [JGit][jgit] team to do the hard part)

## Building
[Eclipse](http://eclipse.org) is recommended for development as the project settings are preconfigured.

1. Clone the git repository from [Github][gitbltsrc].
2. Import the gitblit project into your Eclipse workspace.<br/>
*There will be lots of build errors.*
3. Using Ant, execute the `build.xml` script in the project root.<br/>
*This will download all necessary build dependencies and will also generate the Keys class for accessing settings.*
4. Select your gitblit project root and **Refresh** the project, this should correct all build problems.
5. Review the settings in `gitblit.properties` in your project root.<br/>
Make sure you set an appropriate value for *git.repositoriesFolder*. 
6. Execute the *com.gitblit.Launcher* class to start Gitblit.
