NAME

sway-ipc - 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.

MESSAGES AND REPLIES

The following message types and their corresponding reply types are currently supported. For all replies, any properties not listed are subject to removal.

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"

}

]

1. GET_WORKSPACES

]

2. SUBSCRIBE

MESSAGE
Subscribe this IPC connection to the event types specified in the message payload. The payload should be a valid JSON array of events. See the EVENTS section for the list of supported events.

EVENTS

Events are a way for client to get notified of changes to sway. A client can subscribe to any events it wants to be notified of changes for. The event is sent in the same format as a reply. The following events are currently available:
