“#include"C 程序中的文本文件作为 char[] [英] "#include" a text file in a C program as a char[]

问题描述

有没有办法在编译时将整个文本文件作为字符串包含在 C 程序中?

Is there a way to include an entire text file as a string in a C program at compile-time?

类似:

• file.txt:

• file.txt:

This is
a little
text file

main.c:

main.c:

#include <stdio.h>
int main(void) {
   #blackmagicinclude("file.txt", content)
   /*
   equiv: char[] content = "This is
a little
text file";
   */
   printf("%s", content);
}

获得一个在标准输出上打印的小程序这是一点文本文件"

obtaining a little program that prints on stdout "This is a little text file"

目前我使用了一个 hackish python 脚本，但它很丑，而且仅限于一个变量名，你能告诉我另一种方法吗?

At the moment I used an hackish python script, but it's butt-ugly and limited to only one variable name, can you tell me another way to do it?

推荐答案

我建议使用 (unix util)xxd 为此.你可以像这样使用它

I'd suggest using (unix util)xxd for this. you can use it like so

$ echo hello world > a
$ xxd -i a

输出:

unsigned char a[] = {
  0x68, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x77, 0x6f, 0x72, 0x6c, 0x64, 0x0a
};
unsigned int a_len = 12;
