Creppl

A very crappy read-eval-print loop for C

Development status

Creppl is not functional yet.

TODOS:

• use OS-provided temp files
• figure out how to compile and execute

Why not to use Creppl

This is basically a fake REPL, but it's just enough to do what I want it to do.
It looks at brackets to identify code blocks, so good luck using them in strings lol. Maybe something like this:

const char LPAREN = 0x28;
printf("Shouldn't have downloaded this thing :%c\n", LPAREN);

Multiline comments can also be somewhat problematic, as this:

>>> #include <stdio.h>
>>> puts("Goodbye, world!");
>>> /*
>>> #include "nuke.h"
>>> Uncommenting the above line could be fatal.
>>> */

is translated into this:

#include <stdio.h>
#include "nuke.h"

int main() {
  puts("Goodbye, world!");
  /*
  Uncommenting the above line could be fatal.
  */
}

Also, the entire file, including previously executed statements, is compiled and executed every time a new statement is finished. For example:

>>> #include <stdio.h>
>>> char *message = "...---...";
>>> printf("Help, %s\n", message);

This prints Help, ...---... as expected. However, adding this line:

>>> puts("SOS");

reruns all of the code, outputting:

Help, ...---...
SOS

(notice the first call to printf was rerun)
