如何强制开发者使用指定提交信息模板？寻求跨Windows与Unix系统的兼容实现方案

The issue here is that your existing pre-commit hook relies on Bash-specific syntax (backticks for command substitution, grep -q, pipe operators) which won't work on Windows—Git hooks there run via Command Prompt (cmd.exe) by default, which doesn’t support those Bash features.

Here are two reliable cross-platform solutions that work seamlessly on both Windows and Unix-like systems:

Solution 1: Use a Node.js Script (Recommended) #

Node.js is inherently cross-platform, so writing a small script avoids shell syntax inconsistencies entirely. Here's how to set it up:

1. Create a new file at your project root named check-commit-template.js:

   const { execSync } = require('child_process');
   
   try {
     // Fetch the current commit.template configuration
     const configuredTemplate = execSync('git config commit.template', { encoding: 'utf8' }).trim();
   
     // Verify it matches our required .gitmessage file
     if (configuredTemplate !== '.gitmessage') {
       console.error('\x1b[31m%s\x1b[0m', 'Commit template not configured correctly!');
       console.error('Please run: git config commit.template .gitmessage');
       process.exit(1);
     }
   
     // If valid, run lint-staged as usual
     execSync('npx lint-staged', { stdio: 'inherit' });
   } catch (error) {
     // Handle case where commit.template isn't set at all (git config exits with code 1)
     if (error.status === 1) {
       console.error('\x1b[31m%s\x1b[0m', 'Commit template not configured!');
       console.error('Please run: git config commit.template .gitmessage');
       process.exit(1);
     }
     // Propagate any other unexpected errors
     throw error;
   }
   

2. Update your package.json husky configuration to use this script:

   "husky": {
     "hooks": {
       "pre-commit": "node check-commit-template.js"
     }
   }
   

This approach is clean, maintainable, and eliminates all OS-specific shell issues.

Solution 2: Inline Node.js One-Liner (For Quick Setup) #

If you prefer not to add a separate file, you can embed the logic directly in your package.json with a Node.js one-liner:

"husky": {
  "hooks": {
    "pre-commit": "node -e \"const {execSync} = require('child_process'); try { const t = execSync('git config commit.template', {encoding:'utf8'}).trim(); if (t !== '.gitmessage') { console.error('Commit template not set correctly. Run: git config commit.template .gitmessage'); process.exit(1); } execSync('npx lint-staged', {stdio:'inherit'}); } catch(e) { if (e.status ===1) { console.error('Commit template not set. Run: git config commit.template .gitmessage'); process.exit(1); } throw e; }\""
  }
}

While this works, it’s less readable than the separate script approach, so the first solution is better for long-term maintenance.

Why Your Original Hook Failed #

Windows' cmd.exe doesn’t understand Bash-specific features like:

• Backtick command substitution (`git config ...`)
• The grep -q silent matching flag
• Pipe chaining directly in the if condition

By switching to Node.js, you bypass all these shell-specific syntax limitations.
