# NAME
|
|
|
|
swaybar-protocol - JSON status line protocol for swaybar
|
|
|
|
# SUMMARY
|
|
|
|
swaybar defines the following JSON protocol to specify what information is
|
|
displayed in the status line on the right side of swaybar. The protocol is
|
|
compromised of a header, that is a JSON object, followed by an infinite JSON
|
|
array that represents the information to display. All communication is done by
|
|
writing the status line to standard output and reading events from standard
|
|
input.
|
|
|
|
# HEADER
|
|
|
|
The header is a JSON object with support for the following properties (only
|
|
_version_ is required):
|
|
[- *PROPERTY*
|
|
:- *DATA TYPE*
|
|
:- *DEFAULT*
|
|
:- *DESCRIPTION*
|
|
|- version
|
|
: integer
|
|
: -
|
|
:[ The protocol version to use. Currently, this must be *1*
|
|
|- click_events
|
|
: boolean
|
|
: false
|
|
: Whether to receive click event information to standard input
|
|
|- cont_signal
|
|
: integer
|
|
: SIGCONT
|
|
: The signal that swaybar should send to continue processing
|
|
|- stop_signal
|
|
: integer
|
|
: SIGSTOP
|
|
: The signal that swaybar should send to stop processing
|
|
|
|
## MINIMAL HEADER
|
|
```
|
|
{
|
|
"version": 1
|
|
}
|
|
```
|
|
|
|
## FULL HEADER
|
|
```
|
|
{
|
|
"version": 1,
|
|
"click_events": true,
|
|
"cont_signal": 18,
|
|
"stop_signal": 19
|
|
}
|
|
```

|
|
# BODY
|
|
|
|
The body is an infinite array, where each element of the array is a
|
|
representation of the status line at the time that the element was written.
|
|
Each element of the array is itself an array of JSON objects, where each
|
|
object represents a block in the status line. Each block can have the following
|
|
properties (only _full_text_ is required):
|
|
|
|
[- *PROPERTY*
|
|
:- *DATA TYPE*
|
|
:- *DESCRIPTION*
|
|
|- full_text
|
|
: string
|
|
:[ The text that will be displayed. *If missing, the block will be skipped.*
|
|
|- short_text
|
|
: string
|
|
: If given and the text needs to be shortened due to space, this will be
|
|
displayed instead of _full_text_
|
|
|- color
|
|
: string
|
|
: The text color to use in #RRGGBBAA or #RRGGBB notation
|
|
|- background
|
|
: string
|
|
: The background color for the block in #RRGGBBAA or #RRGGBB notation
|
|
|- border
|
|
: string
|
|
: The border color for the block in #RRGGBBAA or #RRGGBB notation
|
|
|- border_top
|
|
: integer
|
|
: The height in pixels of the top border. The default is 1
|
|
|- border_bottom
|
|
: integer
|
|
: The height in pixels of the bottom border. The default is 1
|
|
|- border_left
|
|
: integer
|
|
: The width in pixels of the left border. The default is 1
|
|
|- border_right
|
|
: integer
|
|
: The width in pixels of the right border. The default is 1
|
|
|- min_width
|
|
: integer or string
|
|
: The minimum width to use for the block. This can either be given in pixels
|
|
or a string can be given to allow for it to be calculated based on the
|
|
width of the string.
|
|
|- align
|
|
: string
|
|
: If the text does not span the full width of the block, this specifies how
|
|
the text should be aligned inside of the block. This can be _left_
|
|
(default), _right_, or _center_.
|
|
|- name
|
|
: string
|
|
: A name for the block. This is only used to identify the block for click
|
|
events. If set, each block should have a unique _name_ and _instance_ pair.
|
|
|- instance
|
|
: string
|
|
: The instance of the _name_ for the block. This is only used to identify the
|
|
block for click events. If set, each block should have a unique _name_ and
|
|
_instance_ pair.
|
|
|- urgent
|
|
: boolean
|
|
: Whether the block should be displayed as urgent. Currently swaybar utilizes
|
|
the colors set in the sway config for urgent workspace buttons. See
|
|
*sway-bar*(5) for more information on bar color configuration.
|
|
|- separator
|
|
: boolean
|
|
: Whether the bar separator should be drawn after the block. See *sway-bar*(5)
|
|
for more information on how to set the separator text.
|
|
|- separator_block_width
|
|
: integer
|
|
: The amount of pixels to leave blank after the block. The separator text will
|
|
be displayed centered in this gap. The default is 9 pixels.
|
|
|- markup
|
|
: string
|
|
: The type of markup to use when parsing the text for the block. This can
|
|
either be _pango_ or _none_ (default).
|
|
|
|
Other properties may be given and swaybar will ignore any property that it does
|
|
not know. It is recommended to prefix any custom properties with an underscore
|
|
to make it easier to distinguish them from protocol properties.

# CLICK EVENTS
|
|
|
|
If requested in the header, swaybar will write a JSON object, that can be read
|
|
from standard in, when the user clicks on a block. The event object will have
|
|
the following properties:
|
|
|
|
[- *PROPERTY*
|
|
:- *DATA TYPE*
|
|
:- *DESCRIPTION*
|
|
|- name
|
|
: string
|
|
:[ The name of the block, if set
|
|
|- instance
|
|
: string
|
|
: The instance of the block, if set
|
|
|- x
|
|
: integer
|
|
: The x location that the click occurred at
|
|
|- y
|
|
: integer
|
|
: The y location that the click occurred at
|
|
|- button
|
|
: integer
|
|
: The x11 button number for the click. If the button does not have an x11
|
|
button mapping, this will be _0_.
|
|
|- event
|
|
: integer
|
|
: The event code that corresponds to the button for the click
|
|
|- relative_x
|
|
: integer
|
|
: The x location of the click relative to the top-left of the block
|
|
|- relative_y
|
|
: integer
|
|
: The y location of the click relative to the top-left of the block
|
|
|- width
|
|
: integer
|
|
: The width of the block in pixels
|
|
|- height
|
|
: integer
|
|
: The height of the block in pixels
|
|
|
|
*Differences from i3bar's protocol:*
|
|
- _button_ may be _0_ for buttons that do not have x11 button mappings
|
|
- _event_ has been introduced to allow for non-x11 buttons to be represented
|
|
- The _modifiers_ property is not currently added by swaybar
|
