Very simple C library for generic dynamic arrays. It works in a similar way to C++ templates but using macros. It works only for plain old data that do not need memory allocation or a destructor.
Please note that the library is just in early development and many functions are missing.
In C is a common pattern to use arrays that dinamically grows as needed when more elements are added.
The library avoid writing always the same code over and over again and it provides a type-safe implementation.
Here an example:
#include <stdio.h>
#include "array.h"
/* Declare an array of int. Using the inline we don't need to provide an implementation
in a separate file. */
declare_array_inline(int);
int main() {
/* The type array(int) identifies the array of int. */
array(int) myarray = array_init();
/* All the method will use the sintax: array_<method_name>(int)(...). For example array_push(int) is
used to append elements into the array. */
for (int i = 0; i < 100; i++) {
array_push(int)(myarray, i * i);
}
/* Elements can be read by using either the 'element' macro or with the 'array_get(int)' function. */
for (int i = 0; i < myarray->length; i++) {
printf("%i\n", element(myarray, i));
}
array_free(int)(myarray);
return 0;
}
Just add 'array.h' and 'array.c' into your project, that's all.
Libarray is currently provided with a Meson build file and a few simple tests but these are not needed to use the library.
