# UE Git Plugin Manager
2+
3+
A Windows CLI tool for managing the UEGitPlugin across multiple Unreal Engine installations.
4+
5+
## Features
6+
7+
- **One-click setup** for multiple Unreal Engine versions
8+
- **Automatic plugin linking** using Windows junctions
9+
- **Update management** with commit tracking and browser integration
10+
- **Collision detection** and resolution for stock Git plugins
11+
- **Relocation support** when moving the executable
12+
- **Comprehensive diagnostics** and error handling
13+
14+
## Requirements
15+
16+
- Windows 10/11
17+
- Git for Windows (must be in PATH)
18+
- Administrator privileges (for plugin installation)
19+
- Unreal Engine 5.3+ installations
20+
21+
## Installation
22+
23+
1. Download the latest release or build from source
24+
2. Extract `UE-Git-Plugin-Manager.exe` to a permanent location
25+
3. **Right-click `UE-Git-Plugin-Manager.exe` and select "Run as administrator"**
26+
- This is required for creating junctions in Unreal Engine directories
27+
28+
## Building from Source
29+
30+
### Prerequisites
31+
1. **Install Go 1.21+**: Download from https://golang.org/dl/
32+
2. **Install Git for Windows**: Download from https://git-scm.com/download/win
33+
3. **Restart Command Prompt** after installing Go
34+
35+
### Build Options
36+
37+
#### Option 1: Automated Build (Recommended)
38+
```cmd
39+
build.bat
40+
```
41+
42+
#### Option 2: PowerShell Build
43+
```powershell
44+
.\build.ps1
45+
```
46+
47+
#### Option 3: Manual Build
48+
```cmd
49+
go mod init ue-git-plugin-manager
50+
go mod tidy
51+
go build -o UE-Git-Plugin-Manager.exe .
52+
```
53+
54+
### Troubleshooting
55+
- **"Go not recognized"**: Install Go and restart Command Prompt
56+
- **"missing go.sum entry"**: Run `go mod tidy`
57+
- **"git: command not found"**: Install Git for Windows
58+
- **Build fails**: Try running as Administrator
59+
60+
See [SETUP_INSTRUCTIONS.md](SETUP_INSTRUCTIONS.md) for detailed troubleshooting.
61+
62+
## Usage
63+
64+
### First Time Setup
65+
66+
1. Run `UE-Git-Manager.exe`
67+
2. The tool will detect your Unreal Engine installations
68+
3. Select which engines to set up
69+
4. The tool will clone the UEGitPlugin repository and create worktrees
70+
5. Plugin junctions will be created automatically
71+
72+
### Updating Plugins
73+
74+
1. Run the tool and select "Update"
75+
2. View available updates with commit information
76+
3. Click "Update now" to apply updates
77+
78+
### Managing Engines
79+
80+
- **Set up a new engine version**: Add support for newly installed engines
81+
- **Uninstall**: Remove all plugin links and worktrees
82+
- **Advanced**: Configure scan roots, change tracked branch, run diagnostics
83+
84+
## How It Works
85+
86+
The tool uses a sophisticated Git worktree system:
87+
88+
1. **Origin Repository**: Single clone of the UEGitPlugin repository
89+
2. **Worktrees**: Separate working directories for each engine version
90+
3. **Junctions**: Windows symbolic links connecting engines to worktrees
91+
4. **Branch Management**: Each engine gets its own branch tracking the remote
92+
93+
## Configuration
94+
95+
Configuration is stored in `config.json` next to the executable:
96+
97+
```json
98+
{
99+
"version": 1,
100+
"base_dir": ".",
101+
"origin_dir": "repo-origin",
102+
"worktrees_dir": "worktrees",
103+
"default_remote_branch": "dev",
104+
"engines": [...],
105+
"custom_engine_roots": [...]
106+
}
107+
```
108+
109+
## Troubleshooting
110+
111+
### Git Not Found
112+
- Install Git for Windows from https://git-scm.com/download/win
113+
- Ensure Git is in your system PATH
114+
115+
### Permission Denied
116+
- Run the tool as Administrator
117+
- Check that Unreal Engine directories are writable
118+
119+
### Plugin Not Loading
120+
- Check the Diagnostics menu
121+
- Verify junctions are pointing to correct worktrees
122+
- Ensure no plugin name collisions
123+
124+
### Relocation Issues
125+
- If you move the executable, use the Relocate option
126+
- This will update all paths and junctions automatically
127+
128+
