mac下qtcreator代码格式化

代码开发：qtcreator
qtcreator 插件：Beautifier
格式化工具：clang-format

1、Beautifier插件安装

将复现框勾选后重启qtcreator即可。

2、安装clang-format工具

（1）打开终端输入下面命令等待安装完成

brew install clang-format

（2）查看安装路径，并拷贝路径

which clang-format

3、配置qtcreator

顺序一次从左到右

这里可以选择现有的通用的格式化类型，如果使用通用的，直接选择后确定即可完成配置。

也可以选择下面的自定义格式化类型，则步骤如下：

Value部分为自定义格式化规则，可参考如下内容
其中字段的意义参考：https://clang.llvm.org/docs/ClangFormatStyleOptions.html

# .clang-format for Qt Creator
#
# This is for clang-format >= 5.0.
#
# The configuration below follows the Qt Creator Coding Rules [1] as closely as
# possible. For documentation of the options, see [2].
#
# Use ../../tests/manual/clang-format-for-qtc/test.cpp for documenting problems
# or testing changes.
#
# In case you update this configuration please also update the qtcStyle() in src\plugins\clangformat\clangformatutils.cpp

4、代码格式化触发

编辑代码后，快捷键保存代码后会自动触发格式化，此时整个文件都将被格式化为配置的规则。
