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 st(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.

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. diff --git a/dwm/dwm.c b/dwm/dwm.c new file mode 100644 index 0000000..0362114 --- /dev/null +++ b/dwm/dwm.c @@ -0,0 +1,2141 @@ +/* See LICENSE file for copyright and license details. + * + * dynamic window manager is designed like any other X client as well.

Here is why some old grumpy +terminal users wants its backspace to be how he feels it: + + Well, I am going to comment why I want to change the behaviour + of this key. When ASCII was defined in 1968, communication + with computers was done using punched cards, or hardcopy + terminals (basically a typewriter machine connected with the + computer using a serial port). ASCII defines DELETE as 7F, + because, in punched-card terms, it means all the holes of the + card punched; it is thus a kind of 'physical delete'. In the + same way, the BACKSPACE key was a non-destructive backspace, + as on a typewriter. So, if you wanted to delete a character, + you had to BACKSPACE and then DELETE. Another use of BACKSPACE + was to type accented characters, for example 'a BACKSPACE `'. + The VT100 had no BACKSPACE key; it was generated using the + CONTROL key as another control character (CONTROL key sets to + 0 b7 b6 b5, so it converts H (code 0x48) into BACKSPACE (code + 0x08)), but it had a DELETE key in a similar position where + the BACKSPACE key is located today on common PC keyboards. + All the terminal emulators emulated the difference between + these keys correctly: the backspace key generated a BACKSPACE + (^H) and delete key generated a DELETE (^?). + + But a problem arose when Linus Torvalds wrote Linux. Unlike + earlier terminals, the Linux virtual terminal (the terminal + emulator integrated in the kernel) returned a DELETE when + backspace was pressed, due to the VT100 having a DELETE key in + the same position. This created a lot of problems (see [1] + and [2]). Since Linux has become the king, a lot of terminal + emulators today generate a DELETE when the backspace key is + pressed in order to avoid problems with Linux. The result is + that the only way of generating a BACKSPACE on these systems + is by using CONTROL + H. (I also think that emacs had an + important point here because the CONTROL + H prefix is used + in emacs in some commands (help commands).) + + From point of view of the kernel, you can change the key + for deleting a previous character with stty erase. When you + connect a real terminal into a machine you describe the type + of terminal, so getty configures the correct value of stty + erase for this terminal. In the case of terminal emulators, + however, you don't have any getty that can set the correct + value of stty erase, so you always get the default value. + For this reason, it is necessary to add 'stty erase ^H' to your + profile if you have changed the value of the backspace key. + Of course, another solution is for st itself to modify the + value of stty erase. I usually have the inverse problem: + when I connect to non-Unix machines, I have to press CONTROL + + h to get a BACKSPACE. The inverse problem occurs when a user + connects to my Unix machines from a different system with a + correct backspace key. + + [1] http://www.ibb.net/~anne/keyboard.html + [2] http://www.tldp.org/HOWTO/Keyboard-and-Console-HOWTO-5.html + +## But I really want the old grumpy behaviour of my terminal + +Apply [1]. + +[1] http://st.suckless.org/patches/delkey + diff --git a/st/LEGACY b/st/LEGACY new file mode 100644 index 0000000..bf28b1e --- /dev/null +++ b/st/LEGACY @@ -0,0 +1,17 @@ +A STATEMENT ON LEGACY SUPPORT + +In the terminal world there is much cruft that comes from old and unsup‐ +ported terminals that inherit incompatible modes and escape sequences +which noone is able to know, except when he/she comes from that time and +developed a graphical vt100 emulator at that time. + +One goal of st is to only support what is really needed.

terminal emulator. +.SH OPTIONS +.TP +.B \-a +disable alternate screens in terminal +.TP +.BI \-c " class" +defines the window class (default $TERM). +.TP +.BI \-f " font" +defines the +.I font +to use when st is run. +.TP +.BI \-g " geometry" +defines the X11 geometry string. +The form is [=][{xX}][{+-}{+-}]. See +.BR XParseGeometry (3) +for further details. +.TP +.B \-i +will fixate the position given with the -g option. +.TP +.BI \-n " name" +defines the window instance name (default $TERM). +.TP +.BI \-o " iofile" +writes all the I/O to +.I iofile. +This feature is useful when recording st sessions. A value of "-" means +standard output. +.TP +.BI \-T " title" +defines the window title (default 'st'). +.TP +.BI \-t " title" +defines the window title (default 'st'). +.TP +.BI \-w " windowid" +embeds st within the window identified by +.I windowid +.TP +.BI \-l " line" +use a tty +.I line +instead of a pseudo terminal. +.I line +should be a (pseudo-)serial device (e.g. /dev/ttySO on Linux for serial port +0). +When this flag is given +remaining arguments are used as flags for +.BR stty(1). +By default st initializes the serial line to 8 bits, no parity, 1 stop bit +and a 38400 baud rate. The speed is set by appending it as last argument +(e.g. 'st -l 115200'). Arguments before the last one are +.BR stty(1) +flags. If you want to set odd parity on 115200 baud use for example 'st -l +parenb parodd 115200'. Set the number of bits by using for example 'st -l cs7 +115200'. See +.BR stty(1) +for more arguments and cases. +.TP +.B \-v +prints version information to stderr, then exits. +.TP +.BI \-e " command " [ " arguments " "... ]" +st executes +.I command +instead of the shell. If this is used it +.B must be the last option +on the command line, as in xterm / rxvt. +This option is only intended for compability, +and all the remaining arguments are used as a command +even without it. +.SH SHORTCUTS +.TP +.B Break +Send a break in the serial line. +Break key is obtained in PC keyboards +pressing at the same time control and pause. +.TP +.B Ctrl-Print Screen +Toggle if st should print to the +.I iofile. +.TP +.B Shift-Print Screen +Print the full screen to the +.I iofile. +.TP +.B Print Screen +Print the selection to the +.I iofile. +.TP +.B Alt-Shift-Page Up +Increase font size. +.TP +.B Alt-Shift-Page Down +Decrease font size. +.TP +.B Alt-Shift-Home +Reset to default font size. +.TP +.B Shift-Insert +Paste from primary selection (middle mouse button). +.TP +.B Alt-Shift-Insert +Paste from clipboard selection. +.TP +.B Alt-Shift-c +Copy the selected text to the clipboard selection. +.TP +.B Alt-Shift-v +Paste from the clipboard selection. +.SH CUSTOMIZATION +.B st +can be customized by creating a custom config.h and (re)compiling the source +code. This keeps it fast, secure and simple. +.SH AUTHORS +See the LICENSE file for the authors. +.SH LICENSE +See the LICENSE file for the terms of redistribution. +.SH SEE ALSO +.BR tabbed (1), +.BR utmp (1), +.BR stty (1) +.SH BUGS +See the TODO file in the distribution. + diff --git a/st/st.c b/st/st.c new file mode 100644 index 0000000..2594c65 --- /dev/null +++ b/st/st.c @@ -0,0 +1,4404 @@ +/* See LICENSE for license details. */ +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +#include "arg.h" + +char *argv0; + +#define Glyph Glyph_ +#define Font Font_ + +#if defined(__linux) + #include +#elif defined(__OpenBSD__) || defined(__NetBSD__) || defined(__APPLE__) + #include +#elif defined(__FreeBSD__) || defined(__DragonFly__) + #include +#endif + + +/* XEMBED messages */ +#define XEMBED_FOCUS_IN 4 +#define XEMBED_FOCUS_OUT 5 + +/* Arbitrary sizes */ +#define UTF_INVALID 0xFFFD +#define UTF_SIZ 4 +#define ESC_BUF_SIZ (128*UTF_SIZ) +#define ESC_ARG_SIZ 16 +#define STR_BUF_SIZ ESC_BUF_SIZ +#define STR_ARG_SIZ ESC_ARG_SIZ +#define XK_ANY_MOD UINT_MAX +#define XK_NO_MOD 0 +#define XK_SWITCH_MOD (1<<13) + +/* macros */ +#define MIN(a, b) ((a) < (b) ?
