IPC protocol for sway

Description

This details the interprocess communication (IPC) protocol for sway(1). This IPC protocol can be used to control or obtain information from a sway process.

The IPC protocol uses a UNIX socket as the method of communication. The path to the socket is stored in the environment variable SWAYSOCK and, for backwards compatibility with i3, I3SOCK. You can also retrieve the socket path by calling sway --get-socketpath.

Message and Reply Format

The format for messages and replies is:

<magic-string> <payload-length> <payload-type> <payload>

Where
<magic-string> is i3-ipc, for compatibility with i3
<payload-length> is a 32-bit integer in native byte order
<payload-type> is a 32-bit integer in native byte order

For example, sending the exit command would look like the following hexdump:

  00000000 | 69 33 2d 69 70 63 04 00 00 00 00 00 00 00 65 78 |i3-ipc........ex|
  00000010 | 69 74                                           |it              |

The payload for replies will be a valid serialized JSON data structure.

0. Run_command

MESSAGE
Parses and runs the payload as sway commands

REPLY
An array of objects corresponding to each command that was parsed. Each object has the property success, which is a boolean indicating whether the command was successful. The object may also contain the properties error and parse_error. The error property is a human readable error message while parse_error is a boolean indicating whether the reason the command failed was because the command was unknown or not able to be parsed.

Example Reply:

  [
  	{
  		"success": true
  	},
  	{
  		"success": false,
  		"parse_error": true,
  		"error": "Invalid/unknown command"

5. Get_marks

MESSAGE
Retrieve the currently set marks

REPLY
An array of marks current set. Since each mark can only be set for one container, this is a set so each value is unique and the order is undefined.

  [
  	"one",
  	"test"
  ]

6. Get_bar_config (Without a Payload)

MESSAGE
When sending without a payload, this retrieves the list of configured bar IDs

  [
  	"bar-0",
  	"bar-1"
  ]

6. Get_bar_config (with a Payload)
