Homogram

Homogram is a 3rd-party Telegram client for HarmonyOS Next, driven by ArkTS/ArkUI (UI-layer) and Rust (native-layer).

This project is a hobby project and is not affiliated with either Telegram or Huawei.

Branches

• The main branch contains the latest most stable version of Homogram, though it may not be the most feature-rich, it will at least compile and run. (with as few bugs as possible)
• The dev branch may contain bugs, incomplete features, and other issues. It is not guaranteed to compile or run.

Roadmap

• Login with phone number, authorizing with verification code and (optionally) password
• Loading chats and recent N messages
• Rendering text and photo preview in messages
• Sending text messages
• Adaptive dark/light mode
• Jump to reply in chat
• Message prefetching on scroll
• Full-screen view for medias
• Sending medias/files
• Reply to messages
• VOIP integration
• HMS Push Kit (depends on Telegram's server-side support tdlib/td#3057)
• Tons of features from official Telegram client...
• ...and even more!

A detailed Roadmap can be found in the Homogram Project page.

Building

Prerequisites

• A Windows or MacOS device which supports DecEco Studio and Rust toolchain.
• Tested on Mate 60 Pro ALN-AL80 NEXT.0.0.71, OpenHarmony SDK 5.0.0.71 (API 12 Release) and Rust 1.80.0. Other configurations may work but are not guaranteed.

1. Clone the repository:

   git clone https://github.com/HomoArk/Homogram.git --recursive

2. Obtain your own api_id for your application.
3. Fill out values into features/home/src/main/rust/src/tg/config.rs (there is a template file config.rs.template).
4. Setup Rust toolchain and ohos-rs for OpenHarmony: https://ohos.rs/docs/basic/quick-start.html
5. Build the native library in features/home/src/main/native/homogrape:

   cargo xtask dist ..\..\..\..\libs\arm64-v8a\

6. Correctly configure the signature information, and build the project in DevEco Studio.
7. Enjoy! (Or not, because it's still very feature-incomplete and suboptimal)

PRs are welcome! Or you definitely want to fork this project and make your own version. Just don't forget to let me test if you implement something cool!

These projects are the backbone of Homogram and without them, this project would not be possible. Tremendous thanks to @Lonami, @richerfu, and all contributors!
