base_allocator

Allocators' common interface.

Don't use malloc, free directly, use allocator instead, to use custom allocator like tcmalloc, jemalloc easily

This library depends on libft/memory for initialize or move memory.

Caution: it's g_default_base_allocator is NOT compatible with malloc and free.

Note: goal of this project is providing base allocator, not custom heaps and/or middleware.

Usage

To use it, you need to include its header.

#include <ft/base_allocator.h>

Include *_types.h instead if you don't want included size get too bigger and only need types not function prototypes (e.g. in header files for custom heap and/or middleware)

#include <ft/base_allocator_types.h>

Call ft_* functions (recommended)

You can use calloc's functionality using ft_calloc, and more functions such as ft_xalloc, ft_rcalloc, ft_memdup, but with some more code.

t_base_allocator    g_allocator = g_default_base_allocator;

// ...

T *new_array(T initial_value, size_t count)
{
    T   *result;
    int i;

    result = (T*)(ft_calloc(g_allocator, count, sizeof(T)));
    i = -1;
    if (result)
        while (++i < count)
            result[i] = initial_value;
    return (result);
}

Call allocator's function directly

You can directly call allocator's function, but malloc, realloc, free is only supported.

t_base_allocator    g_allocator = g_default_base_allocator;

// ...

T *new_array(T initial_value, size_t count)
{
    T   *result;
    int i;

    result = (T*)(g_allocator->malloc(count * sizeof(T)));
    i = -1;
    if (result)
        while (++i < count)
            result[i] = initial_value;
    return (result);
}

Contributing

Any PR is welcome if below kept

• DON'T COMMIT FILES WITH 42 HEADER NOT REMOVED
• If possible, keep the Norm

pre-commit hook

Run init.sh to initialize git pre-commit hook.

bash init.sh

Note: POSIX shell is not supported. use bash instead.

It will copy hooks/pre-commit.sh into .git/hooks/pre-commit, and set execute permission on it.

remove 42 header

File history managed by VCS.

Just let VCS handle it, and stop polluting history :)

This pre-commit script will remove 42 header from Makefile and *.{c,h,sh,mk} files

Alternative: run shell command below before every commit, or never touch 42 header

find . -name '*.c' -o -name "*.h" -o -name "*.sh" -o -name "*.mk" -o -name "Makefile" \
| xargs -L1 sh hooks/scripts/42header-remover.sh

dependencies

It will automatically download Github release assets for dependencies described in the ft_header_deps.properties file.

After change dependencies, please run build/script/init-header-deps.sh manually.
