**smsg** - send ipc messages to swindle (forked from [this repository](https://codeberg.org/notchoc/dwlmsg))
```
usage: smsg [-OTLPF]
smsg [-o <output>] -s [-t <tags>] [-l <layout>] [-c <tags>]
smsg [-o <output>] (-g | -w) [-FOotlcvmf]
```
```
options:
-g get
-s set
-w watch
-O get all outputs
-T get number of tags
-L get all available layouts
-P get compositor pid
-F get focused output
-o select output
-t get/set selected tags (set with [+-^.], overwrite with ! prefix)
-l get/set current layout
-c get title and appid of focused client
-v get visibility of statusbar
-m get fullscreen status
-f get floating status
```
```
examples:
# act like dwl stdout
smsg -w
# watch focused client appid and title
smsg -w -c
# get currently focused output
smsg -F
# watch for focused output changes
smsg -w -F
# get all available outputs
smsg -O
# watch available outputs
smsg -w -O
# select tag 1, deselect tag 2, toggle tag 4 on output eDP-1
smsg -o eDP-1 -s -t +-.^
# toggle tag 3, overwriting current tagset (yes, zero-indexed)
smsg -t !2^
# select tag 8 on current output
smsg -s -t 7
# deselect tag 8 on current output
smsg -s -t 7-
# switch to first layout (order given by smsg -L)
smsg -l 0
# switch to floating layout
smsg -l '><>'
```

This is largely ripped from somebar's ipc patchset; just with some personal modifications.
I would probably just submit raphi's patchset but I don't think that would be polite.

<protocol name="dwl_ipc_unstable_v2">
<description summary="inter-proccess-communication about dwl's state">
This protocol allows clients to update and get updates from dwl.
Warning! The protocol described in this file is experimental and
backward incompatible changes may be made. Backward compatible
changes may be added together with the corresponding interface
version bump.
Backward incompatible changes are done by bumping the version
number in the protocol and interface names and resetting the
interface version. Once the protocol is to be declared stable,
the 'z' prefix and the version number in the protocol and
interface names are removed and the interface version number is
reset.
