【随手记】vscode中C语言满足KR风格的方法

news 2025/9/4 6:52:03

由于生产需求，需要将编码风格改为K&R，为了方便，决定直接去修改vscode来满足

主要需要修改如下两个文件 settings.json 和 c.json

#settings.json
{"workbench.settings.applyToAllProfiles": ["C_Cpp.suggestSnippets","editor.snippetSuggestions"],"[c]": {"editor.snippetSuggestions": "top"},"C_Cpp.suggestSnippets": false
}

#c.json
