It's like swaymsg (in sway) or i3ipc (in i3) but in native Nim.

You might find these docs for i3ipc useful: https://i3wm.org/docs/ipc.html

See also [the useful examples below](#examples).

## Documentation

See [the documentation for the swayipc module](https://disruptek.github.io/swayipc/swayipc.html) as generated directly from the source.

## Usage

```nim

import asyncdispatch

from strutils import spaces

import swayipc

proc dump(tree: TreeReply; indent=0) =

  echo indent.spaces, tree.id, " ", tree.`type`

  for n in tree.nodes:

    n.dump(indent + 2)

  for n in tree.floating_nodes:

    n.dump(indent + 2)

var

  # connect to a compositor at an optional socket path

  compositor = waitFor newCompositor("../some/path")

  # synchronous tree retrieval

  reply = compositor.invoke(GetTree)

dump(reply.tree)

#1 root

#  2147483647 output

#    2147483646 workspace

#  15 output

#    26 workspace

#      28 con

#      39 con

#      49 floating_con

#    37 workspace

#      36 con

#    38 workspace

#      34 con

#    50 workspace

#      6 floating_con

#    7 workspace

#      5 con

# you can pass extra arguments for a command (as strings)

reply = waitFor GetBarConfig.invoke("status")

assert reply.bar.config.mode == "hide"

# you can invoke `send` to instantiate the compositor

block:

  var

    compositor = waitFor RunCommand.send("opacity 0.5")

    # receive the reply

    receipt = waitFor compositor.recv()

    # maybe you want to twiddle your own json?

    js = receipt.data

    # or, nah, that's silly...

    reply = receipt.reply

  # multiple command results are returned as a sequence

  assert reply.ran[0].success

# an example subscription iterator:

iterator focusChanges(): WindowEvent =

  let compositor = waitFor Subscribe.send("[\"window\"]")

  while true:

    let receipt = waitFor compositor.recv()

    if receipt.kind != EventReceipt:

      continue

    if receipt.event.kind != Window:

      continue

    if receipt.event.change != "focus":

      continue

    yield receipt.event.window

for window in focusChanges():

  echo window.name, " now has focus"

```
