javascript - 在 package.json 中执行 precommit hook 时如何获取文件路径？

Question

现在在 package.json 中我设置了 "precommit": "lint node internal/scripts/precommit"，我想获取所有提交的文件路径我的precommit.js，有什么办法可以解决吗？

Answer 1

从“Git pre-commit hook : changed/added files”开始，实际的 Git 命令将是:

git diff --cached --name-only --diff-filter=ACM -z | xargs -0 ...

您可以从 templates/hooks--pre-commit.sample 中看到一种可能的用法.
它也实际用于 JavaScript Standard Style GitHub repo 。

最后，请使用 spawnSync ，如“Catching Fatal Errors with Node.js child_process”

The best way to catch errors without letting your app brick is by using the process' spawn (or in this case spawnSync) method:

var childProcess = require('child_process');

var commitMessage = (function() {
    var spawn = childProcess.spawnSync('git', ['log', '--format=%B', '-n', '1']);
    var errorText = spawn.stderr.toString().trim();

    if (errorText) {
      console.log('Fatal error from `git log`.  You must have one commit before deploying.');
      throw new Error(errorText);
    }
    else {
      return spawn.stdout.toString().trim();
    }
})();

With this method you can check the stderr buffer first; if there's a String from it you know it errored out, if no error text then the process was clean!

根据您的钩子(Hook)情况调整此方法，并按照上面建议的更改其 Git 命令。
