There are two tasks I end up doing manually in C a lot and I’d like to
not.
Thing one: putting guards around header files.
Any `module.h` should start with:
```
#ifndef MODULE_H
#define MODULE_H
```
and end with:
```
#endif /* !MODULE_H */
```
I usually get a few minutes into writing the header file and then
remember that I need have an include guard. I’d like to be able to hit
a key or select a menu item in order to add it. The name of the guard
should be derived from the file name.
Thing two: maintaining function prototypes in header files.
Given a `file.c`, prototypes for all non-static functions should exist
in the counterpart `file.h`.
So given `file.c`:
```
void file_init(int a, int b)
{
/* stuff here */
}
static void helper(void)
{
/* more stuff */
}
void file_scan(int a, int c)
{
/* and again */
}
```
The corresponding `file.h` should look contain:
```
void file_init(int a, int b);
void file_scan(int a, int c);
```
Again, I’d like to, from a C source file, hit a key or select a menu
item to add prototypes in the corresponding C header file. Bonus points
if the command creates the header file if it doesn’t exist yet, and
adds the appropriate include guard. More bonus points if it can update
existing prototypes if I change the return type or parameter list.
Does that all make sense?
I imagine AppleScript would be involved.
Don’t feel like you have to write this for me, but if you already have
tools to do this (or part of this) please point me in their direction.
Thanks for any ideas!
