meillo@754 4 *
meillo@754 5 * dynamic window manager is designed like any other X client as well. It is
meillo@754 6 * driven through handling X events. In contrast to other X clients, a window
meillo@754 7 * manager selects for SubstructureRedirectMask on the root window, to receive
meillo@754 8 * events about window (dis-)appearance. Only one X connection at a time is
meillo@754 9 * allowed to select for this event mask.
meillo@754 10 *
meillo@754 11 * Calls to fetch an X event from the event queue are blocking. Due reading
meillo@754 12 * status text from standard input, a select()-driven main loop has been
meillo@754 13 * implemented which selects for reads on the X connection and STDIN_FILENO to
meillo@754 14 * handle all data smoothly. The event handlers of dwm are organized in an
meillo@754 15 * array which is accessed whenever a new event has been fetched. This allows
meillo@754 16 * event dispatching in O(1) time.
meillo@754 17 *
meillo@754 18 * Each child of the root window is called a client, except windows which have
meillo@754 19 * set the override_redirect flag. Clients are organized in a global
meillo@754 20 * doubly-linked client list, the focus history is remembered through a global
meillo@766 21 * stack list. [...]
meillo@754 22 *
meillo@754 23 * Keys and tagging rules are organized as arrays and defined in the config.h
meillo@771 24 * file. [...] The current mode is represented by the arrange() function
meillo@771 25 * pointer, which wether points to [domax()] or dotile().
meillo@754 26 *
meillo@754 27 * To understand everything else, start reading main.c:main().
meillo@766 28 *
meillo@766 29 * -- and now about aewl --
meillo@766 30 *
meillo@766 31 * aewl is a stripped down dwm. It stated as a patchset, but finally forked off
meillo@766 32 * completely. The reason for this was the increasing gap between my wish to
meillo@766 33 * stay where dwm was, and dwm direction to go further. Further more did I
meillo@766 34 * always use only a small subset of dwm's features, so condencing dwm had been
meillo@766 35 * my wish for a long time.
meillo@766 36 *
meillo@766 37 * In aewl clients are either tagged or not (only one tag). Visible are either
meillo@766 38 * all tagged clients or all without the tag.
