Requirements ------------ In order to build dwm you need the Xlib header files. Installation ------------ Edit config.mk to match your local setup (dwm is installed into the /usr/local namespace by default). Afterwards enter the following command to build and install dwm (if necessary as root): make clean install If you are going to use the default bluegray color scheme it is highly recommended to also install the bluegray files shipped in the dextra package. Running dwm ----------- Add the following line to your .xinitrc to start dwm using startx: exec dwm In order to connect dwm to a specific display, make sure that the DISPLAY environment variable is set correctly, e.g.: DISPLAY=foo.bar:1 exec dwm (This will start dwm on display :1 of the host foo.bar.) In order to display status info in the bar, you can do something like this in your .xinitrc: while xsetroot -name "`date` `uptime | sed 's/.*,//'`" do sleep 1 done & exec dwm Configuration ------------- The configuration of dwm is done by creating a custom config.h and (re)compiling the source code. dwm-6.0/config.mk0000644000175000001440000000130311673651026013146 0ustar anselmusers# dwm version VERSION = 6.0 # Customize below to fit your system # paths PREFIX = /usr/local MANPREFIX = ${PREFIX}/share/man X11INC = /usr/X11R6/include X11LIB = /usr/X11R6/lib # Xinerama XINERAMALIBS = -L${X11LIB} -lXinerama XINERAMAFLAGS = -DXINERAMA # includes and libs INCS = -I. -I/usr/include -I${X11INC} LIBS = -L/usr/lib -lc -L${X11LIB} -lX11 ${XINERAMALIBS} # flags CPPFLAGS = -DVERSION=\"${VERSION}\" ${XINERAMAFLAGS} #CFLAGS = -g -std=c99 -pedantic -Wall -O0 ${INCS} ${CPPFLAGS} CFLAGS = -std=c99 -pedantic -Wall -Os ${INCS} ${CPPFLAGS} #LDFLAGS = -g ${LIBS} LDFLAGS = -s ${LIBS} # Solaris #CFLAGS = -fast ${INCS} -DVERSION=\"${VERSION}\" #LDFLAGS = ${LIBS} # compiler and linker CC = cc dwm-6.0/config.def.h0000644000175000001440000001343411673651026013533 0ustar anselmusers/* See LICENSE file for copyright and license details. */ /* appearance */ static const char font[] = "-*-terminus-medium-r-*-*-16-*-*-*-*-*-*-*";

It manages windows in tiled, monocle and floating layouts. Either layout can be applied dynamically, optimising the environment for the application in use and the task performed. .P In tiled layouts windows are managed in a master and stacking area. The master area contains the window which currently needs most attention, whereas the stacking area contains all other windows. In monocle layout all windows are maximised to the screen size. In floating layout windows can be resized and moved freely. Dialog windows are always managed floating, regardless of the layout applied. .P Windows are grouped by tags. Each window can be tagged with one or multiple tags. Selecting certain tags displays all windows with these tags. .P Each screen contains a small status bar which displays all available tags, the layout, the title of the focused window, and the text read from the root window name property, if the screen is focused. A floating window is indicated with an empty square and a maximised floating window is indicated with a filled square before the windows title. The selected tags are indicated with a different color. The tags of the focused window are indicated with a filled square in the top left corner. The tags which are applied to one or more windows are indicated with an empty square in the top left corner. .P dwm draws a small border around windows to indicate the focus state. .SH OPTIONS .TP .B \-v prints version information to standard output, then exits. .SH USAGE .SS Status bar .TP .B X root window name is read and displayed in the status text area. It can be set with the .BR xsetroot (1) command. .TP .B Button1 click on a tag label to display all windows with that tag, click on the layout label toggles between tiled and floating layout. .TP .B Button3 click on a tag label adds/removes all windows with that tag to/from the view. .TP .B Mod1\-Button1 click on a tag label applies that tag to the focused window. .TP .B Mod1\-Button3 click on a tag label adds/removes that tag to/from the focused window. .SS Keyboard commands .TP .B Mod1\-Shift\-Return Start .BR uxterm (1). .TP .B Mod1\-, Focus previous screen, if any. .TP .B Mod1\-. Focus next screen, if any. .TP .B Mod1\-Shift\-, Send focused window to previous screen, if any. .TP .B Mod1\-Shift\-. Send focused window to next screen, if any. .TP .B Mod1\-b Toggles bar on and off. .TP .B Mod1\-t Sets tiled layout. .TP .B Mod1\-f Sets floating layout. .TP .B Mod1\-m Sets monocle layout. .TP .B Mod1\-space Toggles between current and previous layout. .TP .B Mod1\-j Focus next window. .TP .B Mod1\-k Focus previous window. .TP .B Mod1\-i Increase clients in master area. .TP .B Mod1\-d Decrease clients in master area. .TP .B Mod1\-l Increase master area size. .TP .B Mod1\-h Decrease master area size. .TP .B Mod1\-Return Zooms/cycles focused window to/from master area (tiled layouts only). .TP .B Mod1\-Shift\-c Close focused window. .TP .B Mod1\-Shift\-space Toggle focused window between tiled and floating state. .TP .B Mod1\-Tab Toggles to the previously selected tags. .TP .B Mod1\-Shift\-[1..n] Apply nth tag to focused window. .TP .B Mod1\-Shift\-0 Apply all tags to focused window. .TP .B Mod1\-Control\-Shift\-[1..n] Add/remove nth tag to/from focused window. .TP .B Mod1\-[1..n] View all windows with nth tag. .TP .B Mod1\-0 View all windows with any tag. .TP .B Mod1\-Control\-[1..n] Add/remove all windows with nth tag to/from the view. .TP .B Mod1\-Shift\-q Quit dwm. .SS Mouse commands .TP .B Mod1\-Button1 Move focused window while dragging. Tiled windows will be toggled to the floating state. .TP .B Mod1\-Button2 Toggles focused window between floating and tiled state. .TP .B Mod1\-Button3 Resize focused window while dragging. Tiled windows will be toggled to the floating state. .SH CUSTOMIZATION dwm is customized by creating a custom config.h and (re)compiling the source code. This keeps it fast, secure and simple. .SH SEE ALSO .BR dmenu (1) .SH BUGS Java applications which use the XToolkit/XAWT backend may draw grey windows only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the environment variable .BR AWT_TOOLKIT=MToolkit (to use the older Motif backend instead) or running .B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D or .B wmname LG3D (to pretend that a non-reparenting window manager is running that the XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable .BR _JAVA_AWT_WM_NONREPARENTING=1 . .P GTK 2.10.9+ versions contain a broken .BR Save\-As file dialog implementation, which requests to reconfigure its window size in an endless loop. However, its window is still respondable during this state, so you can simply ignore the flicker until a new GTK version appears, which will fix this bug, approximately GTK 2.10.12+ versions. dwm-6.0/LICENSE0000644000175000001440000000323311673651026012361 0ustar anselmusersMIT/X Consortium License © 2006-2011 Anselm R Garbe © 2007-2011 Peter Hartlich © 2010-2011 Connor Lane Smith © 2006-2009 Jukka Salmi © 2007-2009 Premysl Hruby © 2007-2009 Szabolcs Nagy © 2007-2009 Christof Musik © 2009 Mate Nagy © 2007-2008 Enno Gottox Boland © 2008 Martin Hurton © 2008 Neale Pickett © 2006-2007 Sander van Dijk Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

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(). */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #ifdef XINERAMA #include #endif /* XINERAMA */ /* macros */ #define BUTTONMASK (ButtonPressMask|ButtonReleaseMask) #define CLEANMASK(mask) (mask & ~(numlockmask|LockMask) & (ShiftMask|ControlMask|Mod1Mask|Mod2Mask|Mod3Mask|Mod4Mask|Mod5Mask)) #define INTERSECT(x,y,w,h,m) (MAX(0, MIN((x)+(w),(m)->wx+(m)->ww) - MAX((x),(m)->wx)) \ * MAX(0, MIN((y)+(h),(m)->wy+(m)->wh) - MAX((y),(m)->wy))) #define ISVISIBLE(C) ((C->tags & C->mon->tagset[C->mon->seltags])) #define LENGTH(X) (sizeof X / sizeof X[0]) #define MAX(A, B) ((A) > (B) ?
