为改善开发者日常，Android端推出Git提交专有hook

2023-11-17 15:59:51

在日常的开发过程中，经常会遇到这样的场景：在提交代码前，需要对代码进行规范检查，以确保代码符合团队的规范要求。但这个过程往往需要耗费大量的时间和精力，而且很容易遗漏一些问题。

针对这一问题，Android团队推出了一款专有的Git提交hook，可以帮助开发者在提交代码之前就对代码进行规范检查，从而大大提高开发效率。

这款专有hook的原理非常简单，它会在本地Git仓库中添加一个钩子脚本，在每次提交代码时自动执行。该脚本会对代码进行一系列检查，包括代码风格检查、语法检查、单元测试检查等。如果发现代码不符合规范，则会阻止提交，并提示开发者进行修改。

使用专有hook的好处有很多。首先，它可以帮助开发者在代码提交到代码库之前就发现和解决问题，从而提高代码质量，避免在代码库中出现不规范的代码。其次，它可以帮助开发者养成良好的编码习惯，提高代码的可读性和可维护性。第三，它可以节省开发者的宝贵时间，让他们可以将更多的精力投入到其他更重要的事情上。

如果您是一位Android开发者，那么我强烈建议您使用这款专有hook。它可以帮助您提高代码质量，节省时间，提高开发效率。

以下是使用这款专有hook的步骤：

克隆项目代码库到本地。
在本地Git仓库中，创建一个名为.git/hooks/pre-commit的钩子脚本文件。
将以下内容复制到.git/hooks/pre-commit文件中：

#!/bin/sh
# This script is a pre-commit hook that checks for common errors in the code.
# If any errors are found, the commit will be aborted and a message will be
# printed to the console.

# Check for trailing whitespace
find . -name '*.java' -exec grep -E -l '[[:space:]]+#!/bin/sh
# This script is a pre-commit hook that checks for common errors in the code.
# If any errors are found, the commit will be aborted and a message will be
# printed to the console.

# Check for trailing whitespace
find . -name '*.java' -exec grep -E -l '[[:space:]]+$' {} \;
if [ $? -eq 0 ]; then
  echo "Error: Trailing whitespace found in the following files:"
  find . -name '*.java' -exec grep -E -l '[[:space:]]+$' {} \;
  echo ""
  echo "Please remove the trailing whitespace and try again."
  exit 1
fi
