ubuntu vscode 使用clang-format and editor 插件序列化代码

在使用vscode时， 可以加入插件，在写代码的时候自动格式化代码，对编码风格做一个自动化的处理，这样会使同一个部门使用同一种规格编码，在review代码时会很轻松。

这里使用一键化的shell脚本， 注意：以下三个文件需要在同一个目录下执行， 实际行为就是把.clang-format 和.editorconfig两个配置脚本放置到“～/”下。

code_format_vscode.sh :

#!/bin/bash

user_setting_path="$HOME/.config/Code/User/"
setting_name="settings.json"

whole_setting_path=$user_setting_path$setting_name
echo $whole_setting_path

# used to store .clang-format and .editorconfig
user_path="$HOME/"

#get the extension list on the computer
cmd_code_extension_list="code --list-extensions"
extension_list=`${cmd_code_extension_list}`
echo $extension_list

if [[ ! $extension_list =~ .*ms-vscode.cpptools.* ]]
then
    #install c/c++ extension
    cmd="code --install-extension ms-vscode.cpptools"
    ${cmd}
fi

if [[ ! $extension_list =~ .*EditorConfig.EditorConfig.* ]]
then
    #install EditorConfig.EditorConfig extension
    cmd="code --install-extension EditorConfig.EditorConfig"
    ${cmd}
fi

if [ ! -f "${user_path}.clang-format" ];then
    #copy clang-format configuration to ~/ directory, 
    #so that all vscode workspace could use it
    echo "copy clang-format to ${user_path}"
    cmd="cp .clang-format ${user_path}"
    ${cmd}
else
    echo "you already had a .clang-format file in $user_path directory."
    echo "please check if it is valid"

fi

if [ ! -f "${user_path}.editorconfig" ];then
    #copy editorconfig configuration to ~/ directory, 
    #so that all vscode workspace could use it
    echo "copy editorconfig to ${user_path}"
    cmd="cp .editorconfig ${user_path}"
    ${cmd}
else
    echo "you already had a .editorconfig file in $user_path directory."
    echo "please check if it is valid"
