- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
+Permission is hereby granted, free of charge, to any person obtaining a copy
+of this software and associated documentation files (the "Software"), to deal
+in the Software without restriction, including without limitation the rights
+to use, copy, modify, merge, publish, distribute, sublicense, and/or sell
+copies of the Software, and to permit persons to whom the Software is
+furnished to do so, subject to the following conditions:
 
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-                            NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest

-A rewrite of School 42's MiniLibX using SDL2 and Vulkan. The goal of this version is to give a light, fast and modern graphical tool while keeping the same API as the version currently used at 42.
+###### MacroLibX, a rewrite of 42 School's MiniLibX using SDL2 and Vulkan. 
+The goal of this version is to provide a light, fast, and modern graphical tool while keeping the same API.
 
-# Installation
+## 🌟 Features
 
-## Linux
-Dependances :
+### 🚀 Performances
+Built on top of Vulkan, the MacroLibX takes advantage of its very low-level nature to achieve high performance with great control over available resources.
 
-For Ubuntu/Debian
-```bash
-~ sudo apt update
-~ sudo apt install libsdl2-2.0-0 libsdl2-dev build-essential
+### 💻 Cross-Platform
+Designed to be totally cross-platform, it can run on any SDL2-supported platform that supports Vulkan (even the Nintendo Switch ! theoretically... ).
+
+### 🗿 Close to the old minilibx
+One of the guidelines of this lib was to get as close as possible to the old minilibx API, and therefore to the educational choices of the old minilibx.
+
+### 📖 It's all FOSS
+Everything in this repo is entirely free and open source, all available under the MIT license (even the third-party libraries used).
+
+### 🔍 Valgrind suppressions file
+Experimental for now, a [suppressions file for valgrind](./valgrind.supp) is given to remove potential leaks comming from Xorg, Nvidia drivers, SDL2, or any other tool which the user has no control. It is far from perfect at the moment and may allow some leaks but it will block the majority.
+
+### ⛔ Error system
+Strong error handling informing the user of problems with their code and even capable of informing them of graphics memory leaks that tools like Valgrind cannot detect.
+
+## 🖥️ Installation
+
+### Dependencies
+You first need to install the proper dependencies for your operating-system. 
+
+#### 🐧 Linux
+Here are a few common cases for different Linux distributions:
+
+<details>
+  <summary>
+    For <a href="https://ubuntu.com">Ubuntu</a>/<a href="https://debian.org">Debian</a>-based distros:
+  </summary>
+<pre><code><!--
+-->sudo apt update
+sudo apt install libsdl2-2.0-0 libsdl2-dev build-essential
+</code></pre>
+</details>
+
+<details>
+  <summary>
+    For <a href="https://archlinux.org">ArchLinux</a>-based distros:
+  </summary>
+<pre><code>sudo pacman -S sdl2</code></pre>
+</details>
+
+<br>
+Note that you need to have up do date video drivers with <code>libvulkan.so</code> installed.
+
+#### 🍎 macOS
+[MacroLibX](#) on macOS requires [SDL2](#) and [MoltenVK](https://github.com/KhronosGroup/MoltenVK). You can install both using the [Homebrew](https://brew.sh) package manager:
+```sh
+brew install molten-vk
+brew install SDL2
 ```
 
-For Arch based distros
+### 🪟 Windows
+To build on Windows you may need to use the [xmake](https://xmake.io) build. [Here's](./XMAKE_BUILD.md) how you can use it.
+
+### Clone and Build
+Finally, you can clone the Git repository. When inside it, run the GNU `make` command to compile MacroLibX. 
 ```bash
-~ sudo pacman -S sdl2
+git clone https://github.com/seekrs/MacroLibX.git
+cd MacroLibX
+make
 ```
 
-### MacOS
-Dependances :
-* [MoltenVK](https://github.com/KhronosGroup/MoltenVK/)
-* SDL2 `brew install SDL2`
+## 🔨 Compile your project
+To compile your project with MacroLibX, you just provide the shared library path in your compilation/linking command:
 
-# Get MacroLibX
-
-```bash
-~ git clone https://github.com/420verfl0w/MacroLibX.git
-~ cd MacroLibX
-~ make
+```sh
+clang myApp.c /path/to/MacroLibX/libmlx.so -lSDL2
 ```
 
-# Compile your project
+And you can enjoy your project
 
-```bash
-clang myApp.c MacroLibX/libmlx.so -lSDL2
-```

+</p>
 
-## /!\ If you run into glitches when writing or reading pixels from images /!\
+## ⚙️ Some compilation configurations
 
-You need to add `IMAGES_OPTIMIZED=false` to your make mlx command
+### 📦 Compile mode
+By default the mlx is built in release mode but you can switch to debug by using `make DEBUG=true`.
 
-```bash
-~ git clone https://github.com/420verfl0w/MacroLibX.git
-~ cd MacroLibX
-~ make IMAGES_OPTIMIZED=false
-```
+### 🛠️ Set the toolchain
+If you want to use `GCC` to build the mlx you can use `make TOOLCHAIN=gcc`
+
+### ⚠️⚠️⚠️ 🖼️ Image optimisations ⚠️⚠️⚠️
+If you run into glitches when writing or reading pixels from images you can turn off images optimisations by using `make IMAGES_OPTIMIZED=false`.
+
+### 🖥️ Force the integrated GPU (not recommended)
+You can force the mlx to use your integrated GPU by using `make FORCE_INTEGRATED_GPU=true`. Note that there are a lot of chances that your application crashes by using that.
+
+### 💽 Dump the graphics memory
+The mlx can dump it's graphics memory use to json files every two seconds by enabling this option `make GRAPHICS_MEMORY_DUMP=true`.
+
+## License
+This project and all its files, even the [`third_party`](./third_party) directory or unless otherwise mentionned, are licenced under the [MIT license](./LICENSE).

XMAKE_BUILD.md

@@ -0,0 +1,47 @@
+# 🏗️ xmake build
+To build on Windows (if you don't use [WSL](https://learn.microsoft.com/en-us/windows/wsl/install)), the MacroLibX uses [xmake](https://xmake.io), a build system which will download and compile all dependencies it won't find on your computer.
+
+## 💾 Install xmake
+You can find how to install it on your system [here](https://xmake.io/#/guide/installation). Note that you can also download a [portable version](https://github.com/xmake-io/xmake/releases) of xmake if you wish not to install it.
+
+## ⚙️ Configure the MacroLibX build
+Just as the Makfile build system, you can configure how xmake should build the MacroLibX. The base command to configure it is `xmake config [opts...]` or `xmake f [opts...]`.
+
+### 📦 Compile mode
+You can configure xmake to build the mlx in debug mode or in release mode (release mode is enabled by default). To do so you can use `xmake config --mode=debug` or `xmake config --mode=release`.
+
+### 🛠️ Set the toolchain
+To change the compilation toolchain you can use `xmake config --toolchain=[gcc|clang|...]`
+
+### ⚠️⚠️⚠️ 🖼️ Image optimisations ⚠️⚠️⚠️
+If you run into glitches when writing or reading pixels from images you can turn off images optimisations by using `xmake config --images_optimized=n`.
+
+### 🖥️ Force the integrated GPU (not recommended)
+You can force the mlx to use your integrated GPU using `xmake config --force_integrated_gpu=y`. Note that there are a lot of chances that your application crashes by using that.
+
+### 💽 Dump the graphics memory
+The mlx can dump it's graphics memory use to json files every two seconds by enabling this option `xmake config --graphics_memory_dump=y`.
+
+### 🪛 A possible build configuration
+As a configuration example here's how the command can look like `xmake config --mode=debug --toolchain=clang --graphics_memory_dump=y --images_optimized=n`
+
+## 🚧 Build the lib
+
+### Compile using command-line (first method)
+Once you're ready to compile the lib, run `xmake` (or `xmake -jX` if you wish not to use all your computer threads, with X being the number of threads you wish to use) and watch as the lib compiles.
+
+### Generate a project (second method)
+xmake can also generate a project file for another tool:
+* Visual Studio : `xmake project -k vs`
+* CMakeLists.txt (which you can open in CLion and more) : `xmake project -k cmake`
+* Makefile : `xmake project -k make`
+* Ninja : `xmake project -k ninja`
+* XCode : `xmake project -k xcode`
+
+You should now be able to open the project file with the tool of your choice.
+
+## 😋 Enjoy
+Enjoy you project built with the mlx
