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 on the left contains one window by default, and the stacking area on the +right contains all other windows. The number of master area windows can be +adjusted from zero to an arbitrary number. 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 stderr, then exits. +.SH USAGE +.SS Status bar +.TP +.B X root window name +is read and displayed in the status text area.

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] https://st.suckless.org/patches/delkey + + +## Why do images not work in st using the w3m image hack? + +w3mimg uses a hack that draws an image on top of the terminal emulator Drawable +window.

+.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 [=][<cols>{xX}<rows>][{+-}<xoffset>{+-}<yoffset>]. 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/ttyS0 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 /dev/ttyS0 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 +/dev/ttyS0 parenb parodd 115200'. Set the number of bits by using for +example 'st -l /dev/ttyS0 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 compatibility, +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 Ctrl-Shift-Page Up +Increase font size. +.TP +.B Ctrl-Shift-Page Down +Decrease font size. +.TP +.B Ctrl-Shift-Home +Reset to default font size. +.TP +.B Ctrl-Shift-y +Paste from primary selection (middle mouse button). +.TP +.B Ctrl-Shift-c +Copy the selected text to the clipboard selection. +.TP +.B Ctrl-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), +.BR scroll (1) +.SH BUGS +See the TODO file in the distribution. + diff --git a/laptop/sto/st.c b/laptop/sto/st.c new file mode 100755 index 0000000..79ee9ba --- /dev/null +++ b/laptop/sto/st.c @@ -0,0 +1,2727 @@ +/* See LICENSE for license details. */ +#include <ctype.h> +#include <errno.h> +#include <fcntl.h> +#include <limits.h> +#include <pwd.h> +#include <stdarg.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <signal.h> +#include <sys/ioctl.h> +#include <sys/select.h> +#include <sys/types.h> +#include <sys/wait.h> +#include <termios.h> +#include <unistd.h> +#include <wchar.h> + +#include "st.h" +#include "win.h" + +#if defined(__linux) + #include <pty.h> +#elif defined(__OpenBSD__) || defined(__NetBSD__) || defined(__APPLE__) + #include <util.h> +#elif defined(__FreeBSD__) || defined(__DragonFly__) + #include <libutil.h> +#endif + +/* 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 HISTSIZE 2000 + +/* macros */ +#define IS_SET(flag) ((term.mode & (flag)) != 0) +#define ISCONTROLC0(c) (BETWEEN(c, 0, 0x1f) || (c) == 0x7f) +#define ISCONTROLC1(c) (BETWEEN(c, 0x80, 0x9f)) +#define ISCONTROL(c) (ISCONTROLC0(c) || ISCONTROLC1(c)) +#define ISDELIM(u) (u && wcschr(worddelimiters, u)) +#define TLINE(y) ((y) < term.scr ? term.hist[((y) + term.histi - \ + term.scr + HISTSIZE + 1) % HISTSIZE] : \ + term.line[(y) - term.scr]) + +enum term_mode { + MODE_WRAP = 1 << 0, + MODE_INSERT = 1 << 1, + MODE_ALTSCREEN = 1 << 2, + MODE_CRLF = 1 << 3, + MODE_ECHO = 1 << 4, + MODE_PRINT = 1 << 5, + MODE_UTF8 = 1 << 6, +};
