VScode中自定義用戶代碼片段（C user snippet）自動生成C語言頭文件排除重複包含 原

環境

• WINDOWS 2016
• VSCode v1.25.1

C語言用戶代碼片段SNIPPET配置c.json內容

 

{    
	// Place your snippets for c here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	        
	"C header file": {        
		"prefix": "#ifndef",
        "body": [
			"#ifndef __$1_h__",
			"#define __$1_h__", 
			"", 
			"#ifdef __$1_h__GLOBAL", 
			"\t#define __$1_h__EXTERN ", 
			"#else", 
			"\t#define __$1_h__EXTERN extern", 
			"#endif", 
			"", 
			"$2",		
			"#endif // __$1_h__", 
			"", 

		],
        "description": "C header file define"    
	}
}

結果

輸入#ifndef後按TAB

再輸入 AUTO_GEN_SNIPPET ， 再按TAB ，

輸入  VOID hello(void)  就生成如下了：

#ifndef __AUTO_GEN_SNIPPET_h__
#define __AUTO_GEN_SNIPPET_h__

#ifdef __AUTO_GEN_SNIPPET_h__GLOBAL
    #define __AUTO_GEN_SNIPPET_h__EXTERN 
#else
    #define __AUTO_GEN_SNIPPET_h__EXTERN extern
#endif

VOID HELLO(void);

#endif // __AUTO_GEN_SNIPPET_h__

 

注意如果是頭文件在VSCode中（右下角）要選擇語言語言爲C，不能爲C++或其它，否則沒有自動完成提示功能。

C.JSON修改保存後立即生效，不用重新啓動VSC.

 

 

 自動生成一個更復雜的頭

自動提取.h頭文件名，並把文件名中的-或.改爲_

snippet c.json

	"C head common": {

        "body": [

        "description": "C header file common define"
