Ebcscript

A simple C library for interpreting C sources.

Description

Ebcscript is a library that provides a function of C interpreter for your C program.

Requirements

Ebcscript requires the following to build:

• Bison
• Flex

Building

To build the library:

$ make
parse.y: conflicts: 1 shift/reduce

To run an example:

$ gcc example1.c ebcscrip.a -o example1
$ ./example1
5! = 120

Usage

See the file "example1.c".

example1.c:

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

int main(void)
{
  ebcscript *env;
  char n;
  int v;

  Ebcscript_setFplog(stdout);

  env = newEbcscript(1024);
  Ebcscript_addTrnsunit(env, "factoria.c");
  Ebcscript_resolve(env);

  n = 5;
  Ebcscript_sub_sp(env, sizeof(int));
  Ebcscript_push_char(env, n);
  Ebcscript_call(env, "factorial");
  Ebcscript_add_sp(env, sizeof(char));
  Ebcscript_pop_int(env, &v);

  printf("5! = %d\n", v);

  Ebcscript_removeTrnsunit(env, "factoria.c");
  deleteEbcscript(env);
  return 0;
}

factoria.c:

int factorial(char n)
{
  return (n <= 1) ? 1 : n * factorial(n - 1);
}

To Do

• Preprocessing directives: #include, #define and #ifdef
• A function that accepts a variable number of arguments
