dwm-ipc is a patch for dwm that implements inter-process communication through a UNIX socket. This allows you to query the window manager for information, listen for events such as tag changes or layout changes, as well as send commands to control the window manager from other programs/scripts.
The project is being managed and developed on this GitHub repo. If you discover any bugs, feel free to create an issue there.
In order to build dwm you need the Xlib header files. The patch additionally requires yajl which is a tiny C JSON library.
Applying the Patch
The patch is best applied after all of your other patches due to the number of additions to dwm.c. The patch was designed with compatability in mind, so there are minimal deletions.
At the moment, the patch will only work on systems that implement epoll and is not completely portable. Portability will be improved in the future.
Supported IPC Messages
At the moment the IPC patch supports the following message requests:
- Run user-defined command (similar to key bindings)
Get information about available layouts
Get information about the tags available
Get the properties of all of the monitors
Get the properties of a specific dwm client
Subscribe to tag change, client focus change, layout change events, monitor focus change events, focused title change events, and focused state change events.
For more info on the IPC protocol implementation, visit the wiki.
dwm-msg is a cli program included in the patch which supports all of the IPC
message types listed above. The program can be used to run commands, query dwm
for information, and listen for events. This program is particularly useful for
creating custom shell scripts to control dwm.
