Yet Another i3status replacement written in Go.

• Instant and independent updating of widgets.
• Handling click events.
• Shell scripting widgets and events handlers.
• Wrapping other status programs (i3status, py3status, conky, etc.).
• Different widgets on different workspaces.
• Templates for widgets outputs.
• Update widget via http/websocket requests.
• Update widget by POSIX Real-Time Signals (SIGRTMIN-SIGRTMAX).
• Snippets.
• Plugins.

go get github.com/burik666/yagostatus
mkdir ~/.config/yagostatus
cp $GOPATH/src/github.com/burik666/yagostatus/yagostatus.yml ~/.config/yagostatus/yagostatus.yml

Replace status_command to ~/go/bin/yagostatus --config ~/.config/yagostatus/yagostatus.yml in your i3 config file.

If you using Sway add the --sway parameter.

Yagostatus outputs error messages in stderr, you can log them by redirecting stderr to a file.

status_command exec ~/go/bin/yagostatus --config /path/to/yagostatus.yml 2> /tmp/yagostatus.log

If --config is not specified, yagostatus is looking for yagostatus.yml in $HOME/.config/yagostatus (or $XDG_HOME_CONFIG/yagostatus if set) or in the current working directory.

Yagostatus uses a configuration file in the yaml format.

Example:

widgets:
  - widget: static
    blocks: >
        [
            {
                "full_text": "YaGoStatus",
                "color": "#2e9ef4"
            }
        ]
    events:
      - button: 1
        command: xdg-open https://github.com/burik666/yagostatus/

  - widget: wrapper
    command: /usr/bin/i3status

  - widget: clock
    format: Jan _2 Mon 15:04:05 # https://golang.org/pkg/time/#Time.Format
    templates: >
        [{
            "color": "#ffffff",
            "separator": true,
            "separator_block_width": 21
        }]

• widget - Widget name.
• workspaces - List of workspaces to display the widget.

Example:

- widget: static
  workspaces:
    - "1:www"
    - "2:IM"

  blocks: >
    [
        {
            "full_text": "Visible only on 1:www and 2:IM workspaces"
        }
    ]

- widget: static
  workspaces:
    - "!1:www"

  blocks: >
    [
        {
            "full_text": "Visible on all workspaces except 1:www"
        }
    ]

• templates - The templates that apply to widget blocks.
• events - List of commands to be executed on user actions.
  • button - X11 button ID (0 for any, 1 to 3 for left/middle/right mouse button. 4/5 for mouse wheel up/down. Default: 0).
  • modifiers - List of X11 modifiers condition.
  • command - Command to execute (via sh -c). Сlick_event json will be written to stdin. Also env variables are available: $I3_NAME, $I3_INSTANCE, $I3_BUTTON, $I3_MODIFIERS, $I3_{X,Y}, $I3_OUTPUT_{X,Y}, $I3_RELATIVE_{X,Y}, $I3_{WIDTH,HEIGHT}, $I3_MODIFIERS. The clicked widget fields are available as ENV variables with the prefix I3_ (example: $ I3_full_text).
  • workdir - Set a working directory.
  • env - Set environment variables.
  • output_format - The command output format (none, text, json, auto) (default: none).
  • name - Filter by name for widgets with multiple blocks (default: empty).
  • instance - Filter by instance for widgets with multiple blocks (default: empty).
  • override - If true, previously defined events with the same button, modifier, name and instance will be ignored (default: false)

Example:

- widget: static
  blocks: >
    [
        {
            "full_text": "Firefox",
            "name": "ff"
        },
        {
            "full_text": "Chrome",
            "name": "ch"
        }
    ]
  templates: >
    [
        {
            "color": "#ff8000"
        },
        {
            "color": "#ff3030"
        }
    ]
  events:
    - button: 1
      command: /usr/bin/firefox
      name: ff

    - button: 1
      modifiers:
        - "!Control" # "!" must be quoted
      command: /usr/bin/chrome
      name: ch

    - button: 1
        - Control
      command: /usr/bin/chrome --incognito
      name: ch

Yagostatus supports the inclusion of snippets from files.

  - widget: $ygs-snippets/snip.yaml
    msg: hello world
    color: #00ff00

ygs-snippets/snip.yaml:

variables:
  msg: "default messsage"
  color: #ffffff
widgets:
  - widget: static
    blocks: >
        [
            {
                "full_text": "message: ${msg}",
                "color": "${color}"
            }
        ]

ygs-snippets/snip.yaml - relative path from the current file.

The clock widget returns the current time in the specified format.

• format - Time format (https://golang.org/pkg/time/#Time.Format).
• interval - Clock update interval in seconds (default: 1).

This widget runs the command at the specified interval.

• command - Command to execute (via sh -c).
• workdir - Set a working directory.
• env - Set environment variables.
• interval - Update interval in seconds (0 to run once at start; -1 for loop without delay; default: 0).
• retry - Retry interval in seconds if command failed (default: none).
• silent - Don't show error widget if command failed (default: false).
• events_update - Update widget if an event occurred (default: false).
• output_format - The command output format (none, text, json, auto) (default: auto).
• signal - SIGRTMIN offset to update widget. Should be between 0 and SIGRTMIN-SIGRTMAX.

The current widget fields are available as ENV variables with the prefix I3_ (example: $I3_full_text). For widgets with multiple blocks, an suffix with an index will be added. (example: $I3_full_text, $I3_full_text_1, $I3_full_text_2, etc.)

Use pkill to send signals:

pkill -SIGRTMIN+1 yagostatus

The wrapper widget starts the command and proxy received blocks (and click_events). See: https://i3wm.org/docs/i3bar-protocol.html

• command - Command to execute.
• workdir - Set a working directory.
• 'env' - Set environment variables.

The static widget renders the blocks. Useful for labels and buttons.

• blocks - JSON List of i3bar blocks.

The http widget starts http server and accept HTTP or Websocket requests.

• network - tcp or unix (default tcp).
• listen - Hostname and port or path to the socket file to bind (example: localhost:9900, /tmp/yagostatus.sock).
• path - Path for receiving requests (example: /mystatus/). Must be unique for multiple widgets with same listen.

For example, you can update the widget with the following command:

curl http://localhost:9900/mystatus/ -d '[{"full_text": "hello"}, {"full_text": "world"}]'

Send an empty array to clear:

curl http://localhost:9900/mystatus/ -d '[]'

Unix socket:

curl --unix-socket /tmp/yagostatus.sock localhost/mystatus/ -d '[{"full_text": "hello"}]'

This example shows how you can use custom fields.

• Left mouse button - increment
• Right mouse button - decrement
• Middle mouse button - reset

To get access to weather API you need an APIID. See https://openweathermap.org/appid for details.

Requires jq for json parsing.

    blocks: >
        [
            {
                "full_text": "Weather:",
                "color": "#2e9ef4",
                "separator": false
            }
        ]
  - widget: exec
    command: curl -s 'http://api.openweathermap.org/data/2.5/weather?q=London,uk&units=metric&appid=<APPID>'|jq .main.temp
