Installation

System requirements

Linux with installed hidapi and libudev library
- Archlinux: pacman -S hidapi libudev.so
- Ubuntu: apt-get install libhidapi-dev libudev-dev
Access to /dev/hidraw* for StreamDeck control
Access to /dev/uinput for key_press action

udev configuration

In order to be able to access the StreamDeck as a user and use the key_press action you need to have access to above mentioned devices. This can for example be achieved with this configuration placed into /etc/udev/rules.d/99-streamdeck.rules:

# Allow users to access the /dev/hidraw* devices when added by an Elgato device
ACTION=="add", ATTRS{idVendor}=="0fd9", MODE="0660", GROUP="users"
# Allow users to access uinput (required for Streamdeck)
SUBSYSTEM=="misc", KERNEL=="uinput", MODE="0660", GROUP="users"

After adding the file either reboot once to have them applied or reload the udev rules using this command:

# udevadm control --reload-rules && udevadm trigger

Building

To build the tool you will need to have a working Go development environment.

Most easy way is just to go install github.com/Luzifer/streamdeck/cmd/streamdeck@latest the application.
Alternatively you can download the source and execute a go build inside the cmd/streamdeck directory. This will provide you with a streamdeck binary in said directory.

Configuration

The tool expects to get a configuration file in YAML format.

The config consists of a general part you need to supply:

# Automatically reload on config changes
auto_reload: true

# Optional: int, how much border to give captions in px
caption_border: 5
# Optional: array of int, RGBA color values (4 values, each 0-255)
caption_color: [0xff, 0xff, 0xff, 0xff]
# Font to use when rendering captions on buttons (must be a local path to a TTF file!)
caption_font: /usr/share/fonts/TTF/Roboto-Bold.ttf
# Optional: float, font size to use on captions
caption_font_size: 10.0
# Optional: string, where to place captions (bottom / top)
caption_position: bottom

# Brightness to set on start (0-100)
default_brightness: 20
# Page to display on start
default_page: default
# Optional: Time to display off (0s or leave out for no timeout)
display_off_time: 5m
# Font to use when rendering buttons with text (must be a local path to a TTF file!)
render_font: /usr/share/fonts/TTF/Roboto-Regular.ttf

And a part configuring the different pages and keys on the pages:

pages:

  default:
    overlay: otherpage # Optional: string, put defined keys over current page
    underlay: otherpage # Optional: string, put defined keys under current page
    keys:
      0: # Number of the key (0 = first, 31 = last on a XL, 14 = last on an Original)
        display:
          type: image
          attributes:
            path: /home/myuser/.config/streamdeck/images/lock.png
        actions:
          - type: exec
            attributes:
              command: ["/home/myuser/.config/streamdeck/scripts/lock.sh"]

Each page consists of a name (default in the example above) and key definitions.
Each key consists of a display and one or more action configs.
Each display or action config consists of a type and attributes.

Action modules

Currently these types of actions are supported:

`exec`

This action will call any command on the system specified and detach from it (the command will continue to run in the background even when streamdeck exits).

actions:
  - type: exec
    attributes:
      # Optional: bool, attach to STDERR of process
      attach_stderr: true
      # Optional: bool, attach to STDOUT of process
      attach_stdout: true
      # Required: array of strings, command to execute
      command: ["/usr/bin/bash", "-c", "echo 'Hi there!'"]
      # Optional: map string to string, environment variables to set
      env:
        MYVAR: "myvalue"
      # Optional: bool, wait for command to finish (default: false)
      wait: true

`key_press`

This action will emulate key-presses through the uinput kernel API.

actions:
  - type: key_press
    attributes:
      # Optional: string, time to wait between key presses
      delay: 1s
      # Required: array of int, key codes to press in order
      key_codes: [35, 18, 38, 38, 24]
      # DEPRECATED: array of strings, keys to press in order
      keys: ["c"]
      # Optional: boolean, whether to activate `alt` during key presses
      mod_alt: false
      # Optional: boolean, whether to activate `ctrl` during key presses
      mod_ctrl: false
      # Optional: boolean, whether to activate `shift` during key presses
      mod_shift: false
      # Optional: boolean, whether to activate `meta` (also known as `mod4` or `win`) during key presses
      mod_meta: false

You can get the key codes using the tool evtest, selecting your keyboard and pressing the corresponding keys or looking them up in the kernel key list (all defines starting with KEY_).

As an example when your keyboard is event8 to get the codes for typing "hello":

# sudo evtest /dev/input/event8 | grep 'EV_KEY.*value 1'
Event: time 1591456231.768213, type 1 (EV_KEY), code 35 (KEY_H), value 1
hEvent: time 1591456231.832260, type 1 (EV_KEY), code 18 (KEY_E), value 1
eEvent: time 1591456231.984229, type 1 (EV_KEY), code 38 (KEY_L), value 1
lEvent: time 1591456232.120230, type 1 (EV_KEY), code 38 (KEY_L), value 1
lEvent: time 1591456232.273392, type 1 (EV_KEY), code 24 (KEY_O), value 1
oEvent: time 1591456233.792516, type 1 (EV_KEY), code 29 (KEY_LEFTCTRL), value 1
Event: time 1591456234.096658, type 1 (EV_KEY), code 46 (KEY_C), value 1
