1 /* See LICENSE file for copyright and license details. 2 * 3 * dynamic window manager is designed like any other X client as well. It is 4 * driven through handling X events. In contrast to other X clients, a window 5 * manager selects for SubstructureRedirectMask on the root window, to receive 6 * events about window (dis-)appearance. Only one X connection at a time is 7 * allowed to select for this event mask. 8 * 9 * The event handlers of dwm are organized in an array which is accessed 10 * whenever a new event has been fetched. This allows event dispatching 11 * in O(1) time. 12 * 13 * Each child of the root window is called a client, except windows which have 14 * set the override_redirect flag. Clients are organized in a linked client 15 * list on each monitor, the focus history is remembered through a stack list 16 * on each monitor. Each client contains a bit array to indicate the tags of a 17 * client. 18 * 19 * Keys and tagging rules are organized as arrays and defined in config.h. 20 * 21 * To understand everything else, start reading main(). 22 */ 23 #include <errno.h> 24 #include <locale.h> 25 #include <signal.h> 26 #include <stdarg.h> 27 #include <stdio.h> 28 #include <stdlib.h> 29 #include <string.h> 30 #include <unistd.h> 31 #include <sys/types.h> 32 #include <sys/stat.h> 33 #include <sys/wait.h> 34 #include <X11/cursorfont.h> 35 #include <X11/keysym.h> 36 #include <X11/Xatom.h> 37 #include <X11/Xlib.h> 38 #include <X11/Xproto.h> 39 #include <X11/Xresource.h> 40 #include <X11/Xutil.h> 41 #ifdef XINERAMA 42 #include <X11/extensions/Xinerama.h> 43 #endif /* XINERAMA */ 44 #include <X11/Xft/Xft.h> 45 #include <X11/Xlib-xcb.h> 46 #include <xcb/res.h> 47 #ifdef __OpenBSD__ 48 #include <sys/sysctl.h> 49 #include <kvm.h> 50 #endif /* __OpenBSD */ 51 52 #include "drw.h" 53 #include "util.h" 54 55 /* macros */ 56 #define BUTTONMASK (ButtonPressMask|ButtonReleaseMask) 57 #define CLEANMASK(mask) (mask & ~(numlockmask|LockMask) & (ShiftMask|ControlMask|Mod1Mask|Mod2Mask|Mod3Mask|Mod4Mask|Mod5Mask)) 58 #define INTERSECT(x,y,w,h,m) (MAX(0, MIN((x)+(w),(m)->wx+(m)->ww) - MAX((x),(m)->wx)) \ 59 * MAX(0, MIN((y)+(h),(m)->wy+(m)->wh) - MAX((y),(m)->wy))) 60 #define ISVISIBLE(C) ((C->tags & C->mon->tagset[C->mon->seltags])) 61 #define MOUSEMASK (BUTTONMASK|PointerMotionMask) 62 #define WIDTH(X) ((X)->w + 2 * (X)->bw) 63 #define HEIGHT(X) ((X)->h + 2 * (X)->bw) 64 #define NUMTAGS (LENGTH(tags) + LENGTH(scratchpads)) 65 #define TAGMASK ((1 << NUMTAGS) - 1) 66 #define SPTAG(i) ((1 << LENGTH(tags)) << (i)) 67 #define SPTAGMASK (((1 << LENGTH(scratchpads))-1) << LENGTH(tags)) 68 #define TEXTW(X) (drw_fontset_getwidth(drw, (X)) + lrpad) 69 #define XRDB_LOAD_COLOR(R,V) if (XrmGetResource(xrdb, R, NULL, &type, &value) == True) { \ 70 if (value.addr != NULL && strnlen(value.addr, 8) == 7 && value.addr[0] == '#') { \ 71 int i = 1;
