Matthias

A (soon to be) multiplatform self-hosted chat application built completely in Rust.

Features

Features	Desktop	Mobile

Disclaimer: The application has never been security audited, and has known flaws.

Additional Features (For desktop only):

• Windows installer (Using a Visual Studio project)

Children repositories (Crates/Repos created for the purpose of showcasing/improving Matthias)

• Wincam (Used to capture images from the host's camera)
• Protocol Showcase (Used to showcase Matthias's TCP protocol)
• mLua proc macro (Used in creating the lua API)

---

All this with great performance, due to the project being multi-threaded, using async calls with egui, and many more! I have also tried to make my codebase futureproof by implementing custom automatizations (Example: code generating for emojis) and custom proc macros.

How to compile:

• First, you must have the Rust compiler installed on your computer with all of its dependencies.
• The next step is to download the source code of this project. (whether that be git cloning or downloading it from github's website)
• Navigate to the source folder and run cargo r --release (Or without --release for debugging)
• Please note that some features may not be available when running the application after compilation (For links to work you must "install" the application through the installer provided)

How to create an installer (Note: You must have the Visual Studio installed for this):

• Navigate to desktop/Installer in the project folder, and open up the Matthias.sln file.
• Click on build on the top menu bar and click Build Solution (Or use the ctrl+shift+b key combination)
• After building go to desktop/Installer/MatthiasSetup/Release/ and you will find two files:
  • One containing the dependencies (Smaller file size)
  • One containing the application itself (Bigger file size)
