nheko

The motivation behind the project is to provide a native desktop app for Matrix that feels more like a mainstream chat app (Riot, Telegram etc) and less like an IRC client.

Note regarding End-to-End encryption

Currently the implementation is at best a proof of concept and it should only be used for testing purposes.

Features

Most of the features you would expect from a chat application are missing right now but we are getting close to a more feature complete client. Specifically there is support for: - E2E encryption (text messages only: attachments are currently sent unencrypted). - User registration. - Creating, joining & leaving rooms. - Sending & receiving invites. - Sending & receiving files and emoji (inline widgets for images, audio and file messages). - Typing notifications. - Username auto-completion. - Message & mention notifications. - Redacting messages. - Read receipts. - Basic communities support. - Room switcher (ctrl-K). - Light, Dark & System themes.

Installation

Releases

Releases for Linux (AppImage), macOS (disk image) & Windows (x64 installer) can be found in the Github releases.

Repositories

Arch Linux

pacaur -S nheko # nheko-git

Fedora

sudo dnf install nheko

Gentoo Linux

sudo layman -a matrix
sudo emerge -a nheko

Alpine Linux (and postmarketOS)

Make sure you have the testing repositories from

edge

sudo apk add nheko

Flatpak

flatpak install flathub io.github.mujx.Nheko

macOS (10.12 and above)

with macports :

sudo port install nheko

Build Requirements

• Qt5 (5.7 or greater). Qt 5.7 adds support for color font rendering with Freetype, which is essential to properly support emoji.
• CMake 3.1 or greater.
• mtxclient
• LMDB
• cmark
• Boost 1.66 or greater.
• libolm
• libsodium
• spdlog
• A compiler that supports C++ 14:
  • Clang 5 (tested on Travis CI)
  • GCC 7 (tested on Travis CI)
  • MSVC 19.13 (tested on AppVeyor)

Linux

If you don't want to install any external dependencies, you can generate an AppImage locally using docker.

make docker-app-image

Arch Linux

sudo pacman -S qt5-base \
    qt5-tools \
    qt5-multimedia \
    qt5-svg \
    cmake \
    gcc \
    fontconfig \
    lmdb \
    cmark \
    boost \
    libsodium

Gentoo Linux

sudo emerge -a ">=dev-qt/qtgui-5.7.1" media-libs/fontconfig

Ubuntu (e.g 14.04)

sudo add-apt-repository ppa:beineri/opt-qt592-trusty
sudo add-apt-repository ppa:george-edison55/cmake-3.x
sudo add-apt-repository ppa:ubuntu-toolchain-r-test
sudo apt-get update
sudo apt-get install -y g++-7 qt59base qt59svg qt59tools qt59multimedia cmake liblmdb-dev libsodium-dev 

macOS (Xcode 8 or later)

brew update
brew install qt5 lmdb cmake llvm libsodium spdlog boost cmark

Windows

1. Install Visual Studio 2017's "Desktop Development" and "Linux Development with C++" (for the CMake integration) workloads.

2. Download the latest Qt for windows installer and install it somewhere. Make sure to install the

   MSVC 2017 64-bit

   toolset for at least Qt 5.9 (lower versions does not support VS2017).

3. Install dependencies with

   vcpkg

   . You can simply clone it into a subfolder of the root nheko source directory.

git clone http:\\github.com\Microsoft\vcpkg
cd vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg install --triplet x64-windows \
    boost-asio \
    boost-beast \
    boost-iostreams \
    boost-random \
    boost-signals2 \
    boost-system \
    boost-thread \
    cmark \
    libsodium \
    lmdb \
    openssl \
    zlib

1. Install dependencies not managed by vcpkg. (libolm, libmtxclient, libmatrix_structs)

Inside the project root run the following (replacing the path to vcpkg as necessary).

cmake -G "Visual Studio 15 2017 Win64" -Hdeps -B.deps
        -DCMAKE_TOOLCHAIN_FILE=C:/Users//vcpkg/scripts/buildsystems/vcpkg.cmake
        -DUSE_BUNDLED_BOOST=OFF
cmake --build .deps --config Release
cmake --build .deps --config Debug

Building

First we need to install the rest of the dependencies that are not available in our system

cmake -Hdeps -B.deps \
    -DUSE_BUNDLED_BOOST=OFF # if we already have boost & spdlog installed.
    -DUSE_BUNDLED_SPDLOG=OFF
cmake --build .deps

We can now build nheko by pointing it to the path that we installed the dependencies.

cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=.deps/usr
cmake --build build

If the build fails with the following error ``` Could not find a package configuration file provided by "Qt5Widgets" with any of the following names:

Qt5WidgetsConfig.cmake qt5widgets-config.cmake ``

You might need to pass

e.g on macOS

cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=$(brew --prefix qt5)
cmake --build build

The

nheko

build

Windows

After installing all dependencies, you need to edit the

CMakeSettings.json

You need to fill out the paths for the

CMAKE_TOOLCHAIN_FILE

Qt5_DIR

vcpkg.cmake

lib\cmake\Qt5

Examples for the paths are: -

C:\\vcpkg\\scripts\\buildsystems\\vcpkg.cmake

C:\\Qt\\5.10.1\\msvc2017_64\\lib\\cmake\\Qt5

Now right click into the root nheko source directory and choose

Open in Visual Studio

nheko.exe

Build all

F7

To be able to run the application the last step is to install the needed Qt dependencies next to the nheko binary.

Start the "Qt x.xx.x 64-bit for Desktop (MSVC 2017)" command promt and run

windeployqt

cmd
cd \build-vc\Release\Release
windeployqt nheko.exe

The final binary will be located inside

build-vc\Release\Release

build-vc\Debug\Debug
