# Cross-Platform Git Commit Helper
2+
3+
This directory contains tools to resolve heredoc issues when committing on Windows and ensure consistent cross-platform git commit behavior.
4+
5+
## Problem Solved
6+
7+
The original issue was that heredoc syntax (`<<'EOF'`) used in commit messages only works in bash/Unix shells and fails on Windows Command Prompt. This caused commit failures on Windows systems.
8+
9+
## Files
10+
11+
### Core Scripts
12+
- **`commit-helper.js`** - Main Node.js script that handles cross-platform commits
13+
- **`commit.bat`** - Windows batch wrapper
14+
- **`commit.sh`** - Unix/Linux/macOS shell wrapper
15+
16+
### Utility Libraries
17+
- **`../common/src/util/git-cross-platform.ts`** - TypeScript utility functions for cross-platform git operations
18+
19+
## Usage
20+
21+
### Command Line
22+
23+
#### Windows
24+
```batch
25+
scripts\commit.bat "Your commit message"
26+
scripts\commit.bat "Title" "Body line 1" "Body line 2"
27+
```
28+
29+
#### Unix/Linux/macOS
30+
```bash
31+
scripts/commit.sh "Your commit message"
32+
scripts/commit.sh "Title" "Body line 1" "Body line 2"
33+
```
34+
35+
#### Direct Node.js (Cross-platform)
36+
```bash
37+
node scripts/commit-helper.js "Your commit message"
38+
node scripts/commit-helper.js "Title" "Body line 1" "Body line 2"
39+
```
40+
41+
### Programmatic Usage
42+
43+
#### TypeScript/JavaScript
44+
```typescript
45+
import { commitChanges, commitChangesMultiline } from '../common/src/util/git-cross-platform'
46+
47+
// Simple commit
48+
commitChanges("Fix bug in authentication")
49+
50+
// Multiline commit
51+
commitChangesMultiline("Add new feature", [
52+
"- Implemented user authentication",
53+
"- Added comprehensive tests",
54+
"- Updated documentation"
55+
])
56+
```
57+
58+
#### ES Modules
59+
```javascript
60+
import { createCommitMessage, commitWithTempFile } from './scripts/commit-helper.js'
61+
62+
const message = createCommitMessage(["Fix critical bug"])
63+
commitWithTempFile(message)
64+
```
65+
66+
## Features
67+
68+
### ✅ Cross-Platform Compatibility
69+
- Works on Windows (cmd.exe, PowerShell)
70+
- Works on Unix/Linux/macOS (bash, zsh, fish)
71+
- Handles different line ending conventions
72+
73+
### ✅ Automatic Co-Author Attribution
74+
All commits automatically include:
75+
```
76+
Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>
77+
```
78+
79+
### ✅ Multiline Message Support
80+
- Supports complex commit messages with titles and body
81+
- Handles special characters and quotes safely
82+
- No heredoc syntax issues
83+
84+
### ✅ Fallback Mechanisms
85+
- Primary: Temporary file method (most reliable)
86+
- Fallback: Direct git commit (if temp file fails)
87+
- Graceful error handling
88+
89+
## Technical Details
90+
91+
### How It Works
92+
93+
1. **Input Processing**: Accepts single or multiple arguments for commit messages
94+
2. **Message Formatting**: Combines title and body lines with proper spacing
95+
3. **Co-Author Addition**: Automatically appends factory-droid attribution
96+
4. **Temporary File Method**: Writes message to temp file and uses `git commit -F`
97+
5. **Cleanup**: Removes temporary files after commit
98+
99+
### Why Temporary Files?
100+
101+
The temporary file approach (`git commit -F file`) is used because:
102+
- Avoids shell escaping issues across different platforms
103+
- Handles multiline messages reliably
104+
- Works with any special characters or quotes
105+
- No heredoc syntax required
106+
107+
### Platform-Specific Considerations
108+
109+
#### Windows
110+
- Escapes double quotes in messages
111+
- Uses Windows-style paths for temp files
112+
- Compatible with both cmd.exe and PowerShell
113+
114+
#### Unix/Linux/macOS
115+
- Escapes single quotes and backslashes
116+
- Uses POSIX-style paths
117+
- Compatible with bash, zsh, fish shells
118+
119+
## Error Handling
120+
121+
The helper includes multiple fallback mechanisms:
122+
1. Try temp file approach with co-author
123+
2. Fall back to simple git commit if temp file fails
124+
3. Provide clear error messages for debugging
125+
126+
## Examples
127+
128+
### Simple Commit
129+
```bash
130+
node scripts/commit-helper.js "Fix typo in README"
131+
```
132+
Results in:
133+
```
134+
Fix typo in README

Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>
137+
```
138+
139+
### Complex Multiline Commit
140+
```bash
141+
node scripts/commit-helper.js "Add cross-platform commit helper" "Resolves heredoc issues on Windows" "- Created commit-helper.js script" "- Added Windows batch wrapper" "- Added Unix shell wrapper"
142+
```
143+
Results in:
144+
```
145+
Add cross-platform commit helper
146+
147+
Resolves heredoc issues on Windows
148+
- Created commit-helper.js script
149+
- Added Windows batch wrapper
150+
- Added Unix shell wrapper
151+
152+
Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>
153+
```
154+
155+
## Integration
156+
157+
This helper can be integrated into:
158+
- Build scripts and CI/CD pipelines
159+
- Development workflows
160+
- Automated commit processes
161+
- IDE extensions and tools
162+
163+
The TypeScript utilities in `git-cross-platform.ts` provide a clean API for programmatic use within the Codebuff codebase.
