Tutorial: how to install and use `ydotool` about ydotool HOT 15 OPEN

@ElectricRCAircraftGuy That was a great guide, thank you. I made a script (that i have named ydotool-manage on my computer) based on your guide to start, stop and update from one place.

#!/bin/sh

if [ $# -ne 1 ] || ( [ "$1" != "start" ] && [ "$1" != "stop" ] && [ "$1" != "update" ] && [ "$1" != "status" ] );then
    echo "`basename $0`: missing OPTION
Usage: `basename $0` [OPTION]

    '`basename $0` start' to start the ydotool service.
    '`basename $0` stop' to stop the ydotool service
    '`basename $0` update' to update (or install) ydotool."
  exit 1
fi

# Visa status
if [ "$1" = "status" ]; then
    sudo systemctl status ydotool.service
fi

# Start ydtoold
if [ "$1" = "start" ]; then
    sudo systemctl start ydotool.service
    sudo systemctl status ydotool.service
fi

# Stop ydtoold
if [ "$1" = "stop" ]; then
    sudo systemctl stop ydotool.service
    sudo systemctl status ydotool.service
fi

# Update (update git folder, build and make install) ydotool and ydotoold.
if [ "$1" = "update" ] ; then
    sudo -v

    # pre reqs
    sudo apt update && sudo apt install cmake scdoc pkg-config

    # Check if ydotool repo is downloaded
    if [ ! -d /opt/ydotool ]; then 
        cd /tmp
        git clone https://github.com/ReimuNotMoe/ydotool.git
        sudo mv /tmp/ydotool/ /opt/
    fi

    cd /opt/ydotool/

    # Get latest version
    git pull

    # Make
    mkdir -p build && cd build
    cmake ..
    time make -j "$(nproc)"

    # Install
    sudo make install

    # Remove the need for sudo
    sudo chmod +s $(which ydotool)

    # Install systemd service
    sudo rm /etc/systemd/system/ydotool.service
    sudo ln -s /usr/lib/systemd/user/ydotool.service /etc/systemd/system/
    # Reload the systemd daemon
    sudo systemctl daemon-reload
    # Reload enable the service
    sudo systemctl enable ydotool
    # Reload start ydotool
    sudo systemctl start ydotool
    # Check that it is running
    sudo systemctl status ydotool

    echo "ydotoold version: $(ydotoold --version)"
    echo ""

    if ! grep -q 'export YDOTOOL_SOCKET="/tmp/.ydotool_socket"' $HOME/.profile; then
        echo '' >> "$HOME/.profile"
        echo '# ydotoold socket location' >> "$HOME/.profile"
        echo 'export YDOTOOL_SOCKET="/tmp/.ydotool_socket"' >> "$HOME/.profile"
        echo "YDOTOOL_SOCKET is being exported in $HOME/.profile."
        echo "Please relog to enable the new profile settings."
    fi

fi

EDIT: Now properly installs the service.
More information here https://askubuntu.com/questions/1413829/how-can-i-install-and-use-the-latest-ydotool-keyboard-automation-tool-working-o

EDIT 2: Enable the service after installing it.

EDIT 3: Forgot to install cmake scdoc pkg-config

from ydotool.

I found this where someone explains how to build and install ydotool in detail. It is also explained how to add the service.

I have updated my above script.

from ydotool.

Just in time, I was getting lost trying to install it.

Still having trouble finding how to simulate arrow keys.

Oh, it's just KEY_RIGHT

from ydotool.

@rwjack , yeah, it appears to be KEY_RIGHT, or key code 106, as shown here: https://github.com/torvalds/linux/blob/master/include/uapi/linux/input-event-codes.h#L181

You can view all key codes locally with:

gedit /usr/include/linux/input-event-codes.h

For full instructions to press and release KEY_RIGHT, it should be this:

# Kill the `ydotoold` background running processes
sudo pkill ydotoold

# start the background daemon
sudo -b ydotoold --socket-path="$HOME/.ydotool_socket" --socket-own="$(id -u):$(id -g)"

# press key right, then release it
YDOTOOL_SOCKET="$HOME/.ydotool_socket" ydotool key 106:1 106:0

I don't mention it in my article, but you can also add that environment variable to the bottom of your ~/.bashrc file, as this:

export YDOTOOL_SOCKET="$HOME/.ydotool_socket"

Then you could just run this in place of the last command above:

ydotool key 106:1 106:0

@ElectricRCAircraftGuy Kudos! Thanks bud

from ydotool.

@shellheim I think there are some improvements. I'm wondering that even the ydotool.service is now named ydotoold.service

You also don't need to chown on the socket created, ydotoold accepts this as a parameter when run, so you can edit the service file so you're the owner of the socket, or even change the permission (similar to what a chmod would do), so even that you're not the owner, you can still access the socket

@Paiusco Man, I am so damm grateful to you. Thank you very much. I had completely forgotten about that flag. I am gonna fix the gist in the morning. Again, thank you very much!

edit: the gist should be much better by now.

@ElectricRCAircraftGuy if you have time, let's update that guide, split them into how to install and a use guide? I can help with that. Then we can move towards submitting a PR mentioning those links as a guide

I'm not going to have time :(

I'm a single dad now, and sole income.

from ydotool.

@ecspresso , nice job. There are still more things I don't know. Using systemd to stop/start/restart it may be better. Check out this comment here (all the comments under my answer): https://askubuntu.com/questions/1470593/how-can-i-write-a-program-to-press-keys-such-as-windows-d-in-wayland-repla#comment2596097_1473061

I can see people talking about the service but it seems to be missing for me.

I had it working in a previous system but didn't write it down so wasted quite a few hours figuring it out again, so I did write up here.

Thanks so much for your contribution, I'm very grateful.

I have pinned this issue now.

Is it not possible to make installation as compact as apt install ydotool?

from ydotool.

@Edwardius if you look at #233 you'll see that the package that debian-like distro currently ships is 5years old, so this is controlled by the distro/repo and not by us.
If you want to get something newer, you may move to a "rolling distro" instead.
