This patch currently supports the following requests: * Run custom commands with arguments (similar to key bind functions) * Get monitor properties * Get all available layouts * Get available tags * Get client properties * Subscribe to tag change, client focus change, and layout change, monitor focus change, focused title change, and client state change events This patch includes a dwm-msg cli program that supports all of the above requests for easy integration into shell scripts. The messages are sent in a JSON format to promote integration to increase scriptability in languages like Python/JavaScript. The patch requires YAJL for JSON parsing and a system with epoll support. Portability is planned to be increased in the future. This patch is best applied after all other patches to avoid merge conflicts. For more info on the IPC implementation and how to send/receive messages, documentation can be found at https://github.com/mihirlad55/dwm-ipc

|
|
* dynamic window manager is designed like any other X client as well. It is
|
|
* driven through handling X events. In contrast to other X clients, a window
|
|
* manager selects for SubstructureRedirectMask on the root window, to receive
|
|
* events about window (dis-)appearance. Only one X connection at a time is
|
|
* allowed to select for this event mask.
|
|
*
|
|
* The event handlers of dwm are organized in an array which is accessed
|
|
* whenever a new event has been fetched. This allows event dispatching
|
|
* in O(1) time.
|
|
*
|
|
* Each child of the root window is called a client, except windows which have
|
|
* set the override_redirect flag. Clients are organized in a linked client
|
|
* list on each monitor, the focus history is remembered through a stack list
|
|
* on each monitor. Each client contains a bit array to indicate the tags of a
|
|
* client.
|
|
*
|
|
* Keys and tagging rules are organized as arrays and defined in config.h.
|
|
*
|
|
* To understand everything else, start reading main().
