Discord Messenger for Windows

Discord Messenger is a messenger application designed to be compatible with Discord, while being backwards compatible with down to Windows 2000 (although support for even older versions has been attempted).

Its motto: It's time to ditch MSN and Yahoo.

NOTE: This is beta software, so there may be issues which need to be fixed!

The project is licensed under the MIT license.

Discord Server

A Discord server about this client can be joined here: https://discord.gg/cEDjgDbxJj

Note, you will need to use an official client to accept invitations currently. This may change in the future.

Minimum System Requirements

• Windows NT 3.1, Windows 95, or newer (MinGW version)

• Windows XP SP2 or newer (MSVC version)

• 486 CPU (MinGW version) Pentium 4 CPU (MSVC version)

• 64 MB of RAM, can do lower but might start to hit the page file

Building

Before you can start the build process, after cloning the project (You should NOT download it as ZIP, unless you know that you should also download the submodules individually and unzip them in the correct locations), check out the submodules with the command: git submodule update --init.

Then you can start the build process.

You can build this project in two ways.

1. Visual Studio

This method can only support down to Windows XP SP2, but it's easier to get started with.

1. Compile OpenSSL for Win32, or find a distribution of OpenSSL 3.X.

You can acquire OpenSSL for Win32 from the following website if you don't want to bother with compiling it: https://slproweb.com/products/Win32OpenSSL.html

(Note: Do not download the "Light" versions, as they only contain the DLLs.)

(Note: Download Win64 if you want to compile for x64, Win32 if you want to compile for Win32).

2. Add an entry to your user/system environment variables called OPENSSL_INSTALL. (replace with OPENSSL_INSTALL64 everywhere if you are compiling for 64-bit)

Set its value to the place where your OpenSSL distribution is located.

3. If you want to use a later version of libwebp, acquire libwebp from the following web site: https://developers.google.com/speed/webp/download. Extract the archive and place "libwebp.lib" in vs/libs.

4. Open the Visual Studio solution vs/DiscordMessenger.sln.

5. Click the big play button. (Both x86 and x64 targets are supported.)

6. Enjoy!

2. MinGW

(Note: x64 compilation with MinGW is currently not supported)

1. Acquire MinGW-6.3.0. This is the last version of the original Minimalist GNU for Windows.

NOTE: You might be able to use Mingw-w64 with 32-bit mode, but you might run into trouble running the final product on anything newer than XP.

2. Using the MinGW Installation Manager, install or ensure that the following packages are installed:

   • mingw32-base
   • mingw32-binutils
   • mingw32-gcc
   • mingw32-gcc-core-deps
   • mingw32-gcc-g++
   • mingw32-libatomic
   • mingw32-libgcc
   • mingw32-w32api
   • msys-base
   • msys-bash
   • msys-core
   • msys-make

3. Ensure that both the MinGW bin/ AND msys bin/ directories are in your PATH.

4. Set OPENSSL_INC_DIR and OPENSSL_LIB_DIR in your environment variables to your OpenSSL include and library directories. If you want to remember the paths, edit the Makefile to use those as your defaults (but make sure to not check in your change when sending a PR!)

If you wish to use Shining Light Productions' distribution of OpenSSL-Win32, use the %OPENSSL_INSTALL%/include and %OPENSSL_INSTALL%/lib/MinGW directories for the include and lib dirs respectively.

If you want compatibility on Windows versions which don't support the Microsoft Visual Studio 2015 runtimes (VCRUNTIME140.DLL), then you will need to compile OpenSSL yourself. See the section on Compiling OpenSSL for older Windows versions section.

5. Run the make command.

6. Enjoy!

• Assigning a custom status

Unplanned Features

• Sending friend requests

• Joining servers (7)

Note

1. You may need a modern browser to actually access most links.

2. Only the first 100 users. I plan on changing it.

3. Would take a lot of effort, but theoretically it is possible. No, it's not as simple as hooking certain APIs.

4. Currently, we are using a synchronous HTTP library, with threads to simulate async behavior.

5. Planned for far in the future.

6. Embeds are incomplete, for example, fields don't function properly.

7. Action is weighted by Discord's anti-spam measures. It could cause the target to get autobanned.

8. Some code already exists, but this feature is unfinished and will probably never be finished.

Compiling OpenSSL for older Windows versions

You will need to use the later MinGW forks (not the original one as this project wants). Start by opening mingw32 (from mingw-w64), then cloning the OpenSSL repo. (found at the following link: https://github.com/DiscordMessenger/openssl.git )

Then, run the ./buildit command.

To use the final libraries and DLLs when compiling Discord Messenger, use [OpenSSL repo root]/include as your OPENSSL_INC_DIR, and [OpenSSL repo root] as your OPENSSL_LIB_DIR.

[TODO: Figure out how to avoid this]

[TODO: Maybe remove all scanf uses?]

NOTE: On Windows 2000 and earlier, OpenSSL can't link because it uses _strtoi64 and _strtoui64. Replace these imports with functions likely to return 0 such as iswxdigit and isleadbyte respectively, using a hex editor.

Running on Windows NT 3.1

NOTE: You do not need to follow these steps if you don't intend on running Discord Messenger on Windows NT 3.1.

Windows NT 3.1 doesn't define certain functions in Kernel32 that MinGW libraries expect to be there. It also doesn't come with a copy of MSVCRT.DLL. As such, you must acquire a copy of MSVCRT.DLL (for example, from Windows 95), then patch all of the binaries (including msvcrt.dll but except DiscordMessenger.exe), to replace all of the uppercase KERNEL32.DLL text to DIMEKE32.DLL. Then, download and compile the https://github.com/DiscordMessenger/kernel32shim.git repo with MinGW (the one you used to compile DM) by running make. It should produce a dimeke32.dll executable which you then can place in your installation.

One more thing, you must byte patch DiscordMessenger.exe to report a minimum subsystem version of 3.10 (as opposed to 4.0). The version is located at offset 0xC8 or 200 (check if the bytes match 04 00 00 00). Overwrite it with the following byte string: 03 00 0A 00. Then, save. You must also do this on libgcc_s_dw2-1.dll, libstdc++-6.dll, and msvcrt.dll.

Attributions

Discord Messenger is powered by the following external libraries:

• JSON for Modern C++
• Boost
• Libwebp
• Httplib
• Asio
• Websocketpp

Although these libraries are vendored, you can replace them with the latest version, and the MSVC build will keep working. Adjustments were made to certain libraries to make them compile on MinGW. See doc/ for details.
