+=head1 NAME
+
+tabbedex - tabbed interface to urxvt; extended
+
+=head1 DESCRIPTION
+
+This transforms the terminal into a tabbar with additional terminals, that is,
+it implements what is commonly referred to as "tabbed terminal". tabbedex is an
+extended version of the tabbed plugin which comes with urxvt.
+
+When rxvt-unicode is started with this plugin slave terminals or tabs can be
+started and switched between. 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<Shift-Down>
+
+Creates a new tab.
+
+=item B<Shift-Left> and B<Shift-Right>
+
+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<Meta-F1> through B<Meta-F12>
+
+Switches to the first through twelfth tab.
+
+=item B<Control-Left> and B<Control-right>
+
+Move current tab to the left or right. Wraps around once on the first/last
+position.
+
+=item B<Shift-Up>
+
+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<URxvt.tabbed> which is the same as the tabbed
+extension.
+
+=over
+
+=item B<autohide>: I<boolean>
+
+If set (the default), the tab bar will be hidden unless there are at least two
+tabs open. This is irrespective of whether C<NEW> button or tab's title is
+displayed.
+
+=item B<bell-fg>: I<colour index>
+
+=item B<bell-bg>: I<colour index>
+
+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<COLOUR AND GRAPHICS> in the L<urxvt(1)>
+manpage for valid indices.
+
+=item B<bell-tab-fg>: I<colour index>
+
+=item B<bell-tab-bg>: I<colour index>
+
+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<COLOUR AND GRAPHICS>
+in the L<urxvt(1)> manpage for valid indices. The bell is said to be ringing on
+an active tab for B<bell-timeout> seconds after it started, see B<bell-timeout>.
+
+=item B<bell-timeout>: I<integer>
+
+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<bell-tab-(fg|bg)> styling of tabs.
+
+=item B<new-button>: I<boolean>
+
+If set, a C<NEW> 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<new-tab-command>: I<string>
+
+Specifies how urxvt's B<-e> switch affects tabs created by tabbedex. The
+resource can have one of three values:
+
+=over
+
+=item I<inherit>
+
+The default. The B<-e> command will be used by all tabs created by tabbedex.
+
+=item I<clear>
+
+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<another command>>
+
+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.

+=item B<no-tabbedex-keys>: I<boolean>
+
+If set, the default key bindings (described at the beginning of this document)
+are not initialised. The mappings can be recreated using urxvt's support of
+a keysym.* resource. For example, the following will recreate all the default
+key bindings:
+
+ URxvt.tabbed.no-tabbedex-keys: yes
+ URxvt.keysym.Shift-Left: perl:tabbedex:prev_tab
+ URxvt.keysym.Shift-Right: perl:tabbedex:next_tab
+ URxvt.keysym.Shift-Down: perl:tabbedex:new_tab
+ URxvt.keysym.Shift-Up: perl:tabbedex:rename_tab
+ URxvt.keysym.Control-Left: perl:tabbedex:move_tab_left

+
+=item B<perl-ext-blacklist>: I<string>
+
+A comma-separated list of extensions that must not be loaded into the slave
+terminals (tabs). tabbedex plugin is implicitly added onto the list.
+
+=item B<reopen-on-close>: I<boolean>
+
+If set, whenever last tab is destroyed a new one will be created.
+
+=item B<tabbar-fg>: I<color index>
+
+=item B<tabbar-bg>: I<color index>
+
+Foreground and background colours of the tab bar. (3, 0) by default which
+translates to brown/dark yellow on black background. See I<COLOUR AND GRAPHICS>
+in the L<urxvt(1)> manpage for valid indices.
+
+=item B<tab-fg>: I<color index>
+
+=item B<tab-bg>: I<color index>
+
+Foreground and background colours of the current tab on the tab bar. (0, 1) by
+default which translates to black on red. See I<COLOUR AND GRAPHICS> in the
+L<urxvt(1)> manpage for valid indices.
+
+=item B<tabbar-timeouts>: I<string>
+
+When new text is written to an inactive tab, activity marks are displayed around
+its number (or name if it has one) on the tab bar. By default Unicode
+characters are used to display a block which grows with time the longer it was
+since last time there was any activity in the tab.
+
+This resource allows for this to be customised. It's format is
+
+ ( <timeout> ":" <character> ":" )* <timeout> ":" <character> ":"
+
+where <timeout> is timeout in seconds and <character> is a single activity
+character. If activity character is (, [, { or < it will be used as left
+activity mark and matching character will be used on the right side.
+
+=item B<tabbedex-rs-prefix>: I<string>
+
+By default tabbedex uses the same prefix for resource names as tabbed plugin.
+If this is not desired, the resource can be used to set a new prefix, for
+example:
+
+ URxvt.tabbed.tabbedex-rs-prefix: tabbedex
+
+ ! Affects tabbed only:
+ URxvt.tabbed.tabbar-fg: 4
+ URxvt.tabbed.tabbar-bg: 0
+
+ ! Affects tabbedex only:
+ URxvt.tabbed.tabbar-fg: 5
+ URxvt.tabbed.tabbar-bg: 0
+
+This settings does not affect the B<tabbedex-rs-prefix> resource itself which is
+always read from C<URxvt.tabbed.tabbedex-rs-prefix>.
+
+=item B<title>: I<boolean>
+
+If set (the default), when tab bar is visible and there is enough space left,
+current tab's title will be displayed after the last tab.
+
+=item B<title-fg>: I<color inde>
+
+=item B<title-bg>: I<color inde>
+
+Foreground and background colours of the tab title. (2, 0) by default which
+translates to green on black. Only used when B<title> is true. See I<COLOUR
+AND GRAPHICS> in the L<urxvt(1)> manpage for valid indices.
+

+
+=head1 USER COMMANDS
+
+tabbedex supports several user commands which can be used with
+B<URxvt.keysym>.I<keysym> resource as well as other places. The commands are:
+
+=over
+
+=item B<tabbedex:new_tab>
+
+Creates a new tab.
+
+=item B<tabbedex:next_tab> and B<tabbedex:prev_tab>
+
+Switches to the tab on the right or left of the current tab.
+
+=item B<tabbedex:move_tab_left> and B<tabbedex:move_tab_right>
+
+Moves the current tab left or right.
+
+=item B<goto_tab_>I<N> where I<N> is positive integer
+
+Switches to the tab given by the number I<N>
+
+=item B<tabbedex:kill_tab>
+
+Kills/destroys current tab.
+
+=back
+
+=head1 OSC SEQUENCES
+
+tabbedex supports a single OSC sequence which can be invoked by programs running
+in the terminal by writing a special sequence, namely I<ESC ] 777 ; string ST>
+where I<string> is the command to execute. For example:
+
+ printf '\033]777;tabbedx;set_tab_name;%s\007' "foo"
+
+=over
+
+=item B<tabbedex;set_tab_name;>I<name>
+
+Sets name of the current tab to I<name>.

+## Why does st not handle utmp entries?
+
+Use the excellent tool of [utmp](http://git.suckless.org/utmp/) for this task.
+
+## Some _random program_ complains that st is unknown/not recognised/unsupported/whatever!
+
+It means that st doesn’t have any terminfo entry on your system. Chances are
+you did not `make install`. If you just want to test it without installing it,
+you can manualy run `tic -sx st.info`.
+
+## Nothing works, and nothing is said about an unknown terminal!
+
+* Some programs just assume they’re running in xterm i.e. they don’t rely on
+ terminfo. What you see is the current state of the “xterm compliance”.
+* Some programs don’t complain about the lacking st description and default to
+ another terminal. In that case see the question about terminfo.
+
+## I get some weird glitches/visual bug on _random program_!
+
+Try launching it with a different TERM: $ TERM=xterm myapp. toe(1) will give
+you a list of available terminals, but you’ll most likely switch between xterm,
+st or st-256color. The default value for TERM can be changed in config.h
+(TNAME).
+
+## How do I scroll back up?
+
+Using a terminal multiplexer.
+
+* `st -e tmux` using C-b [
+* `st -e screen` using C-a ESC
+
+## Why doesn't the Del key work in some programs?
+
+Taken from the terminfo manpage:
+
+ If the terminal has a keypad that transmits codes when the keys
+ are pressed, this information can be given. Note that it is not
+ possible to handle terminals where the keypad only works in
+ local (this applies, for example, to the unshifted HP 2621 keys).
+ If the keypad can be set to transmit or not transmit, give these
+ codes as smkx and rmkx. 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. A fast
+solution for them is to use the following command:
+
+ $ printf '\033[?1h\033=' >/dev/tty
+
+or
+ $ tput smkx
+
+In the case of bash, readline is used. Readline has a different note in its
+manpage about this issue:
+
+ enable-keypad (Off)
+ When set to On, readline will try to enable the
+ application keypad when it is called. Some systems
+ need this to enable arrow keys.
+
+Adding this option to your .inputrc will fix the keypad problem for all
+applications using readline.
+
+If you are using zsh, then read the zsh FAQ
+<http://zsh.sourceforge.net/FAQ/zshfaq03.html#l25>:
+
+ It should be noted that the O / [ confusion can occur with other keys
+ such as Home and End. Some systems let you query the key sequences
+ sent by these keys from the system's terminal database, terminfo.
+ Unfortunately, the key sequences given there typically apply to the
+ mode that is not the one zsh uses by default (it's the "application"
+ mode rather than the "raw" mode). 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. If you want it, you have to use the 'st-meta' value
+in TERM.
+
+## I cannot compile st in OpenBSD
+
+OpenBSD lacks librt, despite it being mandatory in POSIX
+<http://pubs.opengroup.org/onlinepubs/9699919799/utilities/c99.html#tag_20_11_13>.
+If you want to compile st for OpenBSD you have to remove -lrt from config.mk, and
+st will compile without any loss of functionality, because all the functions are
+included in libc on this platform.
+
+## The Backspace Case
+
+St is emulating the Linux way of handling backspace being delete and delete being
+backspace.
+
+This is an issue that was discussed in suckless mailing list
+<http://lists.suckless.org/dev/1404/20697.html>. 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.

+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. When you en‐
+counter a sequence which you really need, implement it. But while you
+are at it, do not add the other cruft you might encounter while sneek‐
+ing at other terminal emulators. History has bloated them and there is
+no real evidence that most of the sequences are used today.

+st - simple terminal
+--------------------
+st is a simple terminal emulator for X which sucks less.
+
+
+Requirements
+------------
+In order to build st you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (st is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install st (if
+necessary as root):
+
+ make clean install
+
+
+Running st
+----------
+If you did not install st with make clean install, you must compile
+the st terminfo entry with the following command:
+
+ tic -sx st.info
+
+See the man page for additional details.
+
+Credits
+-------
+Based on Aurélien APTEL <aurelien dot aptel at gmail dot com> bt source code.

+.SH DESCRIPTION
+.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'. 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.
+.TP
+.B Alt-Ctrl
+Launch dmenu to enter a unicode codepoint and send the corresponding glyph
+to st.
+.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.

+tabbed - generic tabbed interface
+=================================
+tabbed is a simple tabbed X window container.
+
+Requirements
+------------
+In order to build tabbed you need the Xlib header files.
+
+Installation
+------------
+Edit config.mk to match your local setup (tabbed is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install tabbed
+(if necessary as root):
+
+ make clean install
+
+Running tabbed
+--------------
+See the man page for details.

+.SH DESCRIPTION
+.B tabbed
+is a simple tabbed container for applications which support XEmbed. Tabbed
+will then run the provided command with the xid of tabbed as appended
+argument. (See EXAMPLES.) The automatic spawning of the command can be
+disabled by providing the -s parameter. If no command is provided
+tabbed will just print its xid and run no command.
+.SH OPTIONS
+.TP
+.B \-c
+close tabbed when the last tab is closed. Mutually exclusive with -f.
+.TP
+.B \-d
+detaches tabbed from the terminal and prints its XID to stdout.
+.TP
+.B \-f
+fill up tabbed again by spawning the provided command, when the last tab is
+closed. Mutually exclusive with -c.
+.TP
+.BI \-g " geometry"
+defines the X11 geometry string, which will fixate the height and width of
+tabbed.
+The syntax is
+.RI [=][ width {xX} height ][{+-} xoffset {+-} yoffset ].
+See
+.BR XParseGeometry (3)
+for further details.
+.TP
+.B \-k
+close foreground tabbed client (instead of tabbed and all clients) when
+WM_DELETE_WINDOW is sent.
+.TP
+.BI \-n " name"
+will set the WM_CLASS attribute to
+.I name.
+.TP
+.BR \-p " [" s {+-}] \fIpos\fR
+will set the absolute or relative position of where to start a new tab. When
+.I pos
+is is given without 's' in front it is an absolute position. Then negative
+numbers will be the position from the last tab, where -1 is the last tab.
+If 's' is given, then
+.I pos
+is a relative position to the current selected tab. If this reaches the limits
+of the tabs; those limits then apply.
+.TP
+.BI \-r " narg"
+will replace the
+.I narg
+th argument in
+.I command
+with the window id, rather than appending it to the end.
+.TP
+.B \-s
+will disable automatic spawning of the command.
+.TP
+.BI \-o " normbgcol"
+defines the normal background color.
+.RI # RGB ,
+.RI # RRGGBB ,
+and X color names are supported.
+.TP
+.BI \-O " normfgcol"
+defines the normal foreground color.
+.TP
+.BI \-t " selbgcol"
+defines the selected background color.
+.TP
+.BI \-T " selfgbcol"
+defines the selected foreground color.
+.TP
+.BI \-u " urgbgcol"
+defines the urgent background color.
+.TP
+.BI \-U " urgfgbcol"
+defines the urgent foreground color.
+.TP
+.B \-v
+prints version information to stderr, then exits.
+.SH USAGE
+.TP
+.B Ctrl\-Shift\-Return
+open new tab
+.TP
+.B Ctrl\-Shift\-h
+previous tab
+.TP
+.B Ctrl\-Shift\-l
+next tab
+.TP
+.B Ctrl\-Shift\-j
+move selected tab one to the left
+.TP
+.B Ctrl\-Shift\-k
+move selected tab one to the right
+.TP
+.B Ctrl\-Shift\-u
+toggle autofocus of urgent tabs
+.TP
+.B Ctrl\-Tab
+toggle between the selected and last selected tab
+.TP
+.B Ctrl\-t
+open dmenu to either create a new tab appending the entered string or select
+an already existing tab.
+.TP
+.B Ctrl\-q
+close tab
+.TP
+.B Ctrl\-u
+focus next urgent tab
+.TP
+.B Ctrl\-[0..9]
+jumps to nth tab
+.TP
+.B F11
+Toggle fullscreen mode.
+.SH EXAMPLES
+$ tabbed surf -e
+.TP
+$ tabbed urxvt -embed
+.TP
+$ tabbed xterm -into
+.TP
+$ $(tabbed -d >/tmp/tabbed.xid); urxvt -embed $(</tmp/tabbed.xid);
+.TP
+$ tabbed -r 2 st -w '' -e tmux
+.SH CUSTOMIZATION
+.B tabbed
+can be customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.

+.TH XEMBED 1 tabbed\-VERSION
+.SH NAME
+xembed \- XEmbed foreground process
+.SH SYNOPSIS
+.B xembed
+.I flag command
+.RI [ "argument ..." ]
+.SH DESCRIPTION
+If the environment variable XEMBED is set, and
+.B xembed
+is in the foreground of its controlling tty, it will execute
+.IP
+command flag $XEMBED [argument ...]
+.LP
+Otherwise it will execute
+.IP
+command [argument ...]
+.LP
+.SH EXAMPLE
+In a terminal emulator within a
+.B tabbed
+session, the shell alias
+.IP
+$ alias surf='xembed -e surf'
+.LP
+will cause `surf' to open in a new tab, unless it is run in the background,
+i.e. `surf &', in which case it will instead open in a new window.
