One of the terminals is the current or active one +and it is the only one that is visible. rxvt-unicode will exit once all tabs +are closed. + +Once at least two slave terminals are created a tab bar is displayed at the top +of the window which lists all the slave terminals. Clicking on a number/name of +a tab on that bar switches to given tab. + +=head2 Key bindings + +Creating new tabs, switching between them and moving them around is accomblished +by the following key bindings: + +=over + +=item B + +Creates a new tab. + +=item B and B + +Switches to the tab on the left or on the right of the current tab. Movement +wraps around once at the first or last tab. + +=item B through B + +Switches to the first through twelfth tab. + +=item B and B + +Move current tab to the left or right. Wraps around once on the first/last +position. + +=item B + +Allows current tab to be renamed. Start typing desired new name and press +Return to confirm or Escape to cancel. + +=back + +=head1 CONFIGURATION + +The extension can be configured similarly to a normal terminal. By default, it +uses a resource class of C which is the same as the tabbed +extension. + +=over + +=item B: I + +If set (the default), the tab bar will be hidden unless there are at least two +tabs open. This is irrespective of whether C button or tab's title is +displayed. + +=item B: I + +=item B: I + +Foreground and background colours of an inactive tab on which bell has rung. +(0, 3) by default which translates to black on brown/dark yellow (i.e. inverse +of the default tab bar colours). See I in the L +manpage for valid indices. + +=item B: I + +=item B: I + +Foreground and background colours of a active tab in which bell is ringing. (5, +4) by default which translates to magenta an blue. See I +in the L manpage for valid indices. The bell is said to be ringing on +an active tab for B seconds after it started, see B. + +=item B: I + +Time in seconds, one second by default, a bell is said to be ringing on current +tab for after it was rung. Setting this to zero essentially disables the +B styling of tabs. + +=item B: I + +If set, a C button will be displayed on the left of the tab bar. Clicking +the button creates a new tab. It is not displayed by default. + +=item B: I + +Specifies how urxvt's B<-e> switch affects tabs created by tabbedex. The +resource can have one of three values: + +=over + +=item I + +The default. The B<-e> command will be used by all tabs created by tabbedex. + +=item I + +Only the initial tab will use the B<-e> switch provided on urxvt's command line. +All other tabs will act as if the option was not provided. + +=item I<-e B> + +The initial tab will use the B<-e> switch provided on urxvt's command line (if +any) while all other tabs will use switch specified by this setting. Note that +parsing of the resource simply splits words on white space so things like I<-e +my-prog "argument with spaces"> will not work. + +=back + +=item B: I + +If set, the default key bindings (described at the beginning of this document) +are not initialised.

Otherwise the keypad is assumed to + always transmit. + +In the st case smkx=E[?1hE= and rmkx=E[?1lE>, so it is mandatory that +applications which want to test against keypad keys send these +sequences. + +But buggy applications (like bash and irssi, for example) don't do this.

Explaining the use of terminfo is + outside of the scope of this FAQ, but if you wish to use the key + sequences given there you can tell the line editor to turn on + "application" mode when it starts and turn it off when it stops: + + function zle-line-init () { echoti smkx } + function zle-line-finish () { echoti rmkx } + zle -N zle-line-init + zle -N zle-line-finish + +Putting these lines into your .zshrc will fix the problems. + +## How can I use meta in 8bit mode? + +St supports meta in 8bit mode, but the default terminfo entry doesn't +use this capability.

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.

+.B st +is a simple 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 [=][<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'.
