git clone https://github.com/mwarevn/ibus-unikey.git

cd ibus-unikey

1. Install required packages:

   sudo apt-get install -y cmake g++ make pkg-config libibus-1.0-dev libgtk-3-dev gettext
   

2. Build & install

   mkdir build
   cd build
   cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=release -DLIBEXECDIR=/usr/lib/ibus ..
   sudo make
   sudo make install
   

3. Apply the keyboard input method

   Step 1: Install Vietnamese Language Support

   You must have the "Language Support" application installed.

   • Open the Language Support application.
   • In the list of available languages, locate Vietnamese.
   • If Vietnamese is not installed, select it and click Install.
   • Change your keyboard input method system to IBus. (The exact steps for this may vary depending on your operating system)

   Step 2: Configure IBus for Vietnamese

   • Open a terminal window.
   • Run the command ibus-setup.
   • Navigate to the Input Method tab.
   • If Vietnamese - Unikey is not listed, click Add and select it.
   • Close the ibus-setup window.
   • In the same terminal window, run the command ibus restart.

   Step 3: Select IBus in System Settings

   • Run im-config in the terminal.
   • When prompted for user configuration, select ibus.

   Step 4: Finalize Setup

   • Restart your computer.
   • Open your system Settings.
   • Navigate to the input method settings. (This location may vary depending on your operating system)
   • Change the input method to Vietnamese.

   You should now be able to type in Vietnamese!

This instruction is for FreeBSD 12-RELEASE.

Build and install:

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=release -DLIBEXECDIR=/usr/local/lib ..
make
sudo make install

If you use GNOME, ibus-unikey should work once IBus is configured correctly.

If you use KDE, some additional configuration is needed:

1. Add

   export GTK_IM_MODULE=ibus
   export XMODIFIERS=@im=ibus
   export QT_IM_MODULE=ibus
   

into $HOME/.profile.

2. Make ibus-daemon start automatically with the right configuration:

   $ echo "ibus-daemon -d -x -r -n kde" > $HOME/.kde/Autostart/ibus-daemon-autostart.sh && chmod +x $HOME/.kde/Autostart/ibus-daemon-autostart.sh
