$|code-block|syntax|javascript|3084070|这与Steve+Ward发布的答案类似，但这个答案需要sed和tr，而不是jq。|3084071|entityMap|0|LINK|mutability|MUTABLE|url|https://ctags.io/^0|E|G|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@$A|T|B|U|1|V]]|C|$]]|$1|D|3|E|5|F|7|W|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|X|8|@]|9|@]|C|$]]|$1|K|3|-4|5|6|7|Y|8|@]|9|@]|C|$]]]|L|$M|$5|N|O|P|C|$Q|R]]]]

If you have universal-ctags (<a href="https://ctags.io" rel="nofollow noreferrer">https://ctags.io</a>), --_xformat option may be useful though you need sed and tr commands to get what you want.
<pre><code>$ cat input.c 
struct object *new_object (struct

 *p)
{
 return NULL;
}
int main (void)
{

$ ./ctags -o - --kinds-C=f --kinds-C++=f -x --_xformat='%{typeref} %{name} %{signature};' input.c | tr ':' ' ' | sed -e 's/^typename //'

This is similar to the answer posted by Steve Ward but this one requires sed, and tr instead of jq.

I used to use doxygen to generate documentation for my C++ code. I am not an expert, but i think you can use doxygen to generate some sort of index file of the function prototypes.

If you format your comments suitably, you could try <a href="http://www.doxygen.nl/" rel="nofollow noreferrer">DOxygen</a>. In fact, if you've not tried it before I'd recommend giving it a go anyway - it will produce inheritance graphs as well as full member function lists and descriptions (from your comments).

You can run the source file through this program:

<pre><code>/* cproto_parser.c */
#include &lt;stdio.h&gt; 
int main (void) 
{ 
 int c; 
 int infundef = 0; 
 int nb = 0, 
 np = 0; 
 while((c=getc(stdin))!=EOF){ 
 if(c=='{'){ 
 if((np==0)&amp;&amp;(nb==0)){infundef=1;}
 nb++; 
 } 
 if (infundef==0) {putc(c,stdout);} 
 if(c=='}'){ 
 if((np==0)&amp;&amp;(nb==1)){infundef=0;}
 nb--; 
 } 
 if(c=='('){np++;} 
 if(c==')'){np--;} 
 } 
 return 0; 
} 
</code></pre>

Run through the preprocessor to get rid of comments. If you have unmatched braces due to #ifdefs you have to set defines, include files to make it not so.

e.g., <code>cc cproto_parser.c -o cproto_parser; cc -E your_source_file.c|./cproto_parser</code>

Here's a sample of what the output looks like:
<pre><code>/* src/main.c:30:NC */ static void usage (const char *);
/* src/main.c:32:NF */ extern int main (int argc, char **argv); /* (argc, argv) int argc; char **argv; */
/* src/main.c:57:NF */ static void usage (const char *prog_name); /* (prog_name) const char *prog_name; */
</code></pre>

I want to do this:

<pre><code>extract_prototypes file1.c file2.cpp file3.c
</code></pre>

and have whatever script/program print a nice list of function prototypes for all functions defined in the given C / C++ files. It must handle multi-line declarations nicely.

Is there a program that can do this job? The simpler the better.

EDIT: after trying to compile two C programs, bonus points for something that uses {perl, python, ruby}.

Extracting C / C++ function prototypes

编译器

我想这样做：extract_prototypes file1.c file2.cpp file3.c并让任何脚本/程序为给定的C/ C++文件中定义的所有函数打印一个漂亮的函数原型列表。它必须很好地处理多行声明。有没有可以做这项工作的程序？越简单越好。编辑:在尝试编译两个C程序后，为使用{perl，python，ruby}的内容加分。
