NAME

SYNOPSIS

DESCRIPTION

The screen can be split into non-overlapping frames. All windows are kept maximized inside their frames.

All interaction with the window manager is done through keystrokes. sdorfehs has a prefix map to minimize key clobbering.

The options are as follows:

-c command

Send sdorfehs a command. There must be a sdorfehs instance running as window manager for the given display/screen for this to work. Do not forget to quote the command if it contains spaces. For example:

sdorfehs -c “echo hello world”

-d display

Set the X display to use or send commands to.

-f filename

Specify an alternate configuration file. If this is not given, sdorfehs will try $HOME/.config/sdorfehs/config and execute each command when starting up.

-h

Show summary of options.

-i

Execute commands given with -c in interactive mode. That means it will behave exactly as if called with C-a : like prompting for missing arguments and things like that.

-s number

Only use the specified screen.

KEY BINDINGS

C-a ?

Further default key bindings can be found in parentheses after the commands in the next section.

COMMANDS AND DEFAULT ALIASES

abort

(C-a C-g) Do nothing and that successfully. (Useful if you pressed C-a in error).

addhook event command

Add a hook: run command whenever event is called. Possible events are:

deletewindow

Run after a window is withdrawn.

newwindow

Run after a new window is mapped.

key

Run whenever a top level key is pressed (by default C-a).

quit

Run before exiting sdorfehs.

restart

Run before restarting sdorfehs.

switchframe

Run after a frame actually switched, but before the window in it is focused.

switchscreen

Run when the user switches to a different screen.

switchwin

Run after a new window is selected. (With dedication, it may already be inactive again, if it was put into another frame)

alias alias command

Add alias as new way to call command.

bind key command

alias for “definekey root key command”

banish

(C-a b) Banish the rat cursor to the lower right corner of the screen.

banishrel

Banish the rat cursor to the lower right corner of the current window. If there isn't a window in the current frame, it banishes the rat cursor to the lower right corner of the frame.

chdir [directory]

If the optional argument is given, change the current directory of sdorfehs to directory. If nothing is given, change it to the value of the environment variable “HOME”.

clrunmanaged

Clears the unmanaged window list.

cnext

Like next but switch to the next window with another resource class than the current one. (That means the next window belonging to another type of application than the current one.)

cprev

Like prev but switch to the previous window with another resource class than the current one. (That means the previous window belonging to another type of application than the current one.)

colon sdorfehs-command (C-a :)

Execute sdorfehs-command interactively. (i.e. ask for possible missing arguments.)

cother

Like other but switch to the window of the current vscreen that was last accessed and has another resource class but is not currently visible.

curframe (C-a F)

Show a bar marking the current frame.

definekey keymap key command

Add a new key binding in keymap for key to execute command. Default keymaps are top normally only containing C-a, which reads a key from root, containing all the normal commands.

Note that you have to describe ":" by "colon", "!" by "exclam" and so on. If you cannot guess a name of a key, try either C-a key and look at the error message, or try :describekey root and pressing the key.

dedicate [0 | 1]

Consider the current frame dedicated/chaste (1) or promiscuous (0).

A dedicated frame will not accept new windows. When new windows are to be focused, they will be opened in a non-dedicated frame instead.

If no argument is given, toggle the current dedicateness. By default no windows are dedicated.

delete (C-a k)

Close the current window.

delkmap keymap

Deletes the keymap named keymap, that was generated with newkmap. The keymaps top (or whatever was specified by set topkmap) and root cannot be deleted.

describekey keymap

Grab the next key. Similar to readkey, describekey shows only the command in keymap, that would be executed by readkey.

echo text

Show text as sdorfehs message.

escape key

Update the default escape key to key.

Strictly speaking it updates the readkey root command in the keymap top to key, the other binding in root to key, and meta binding in root to key without modifiers or C-key if key has no modifiers. (If set topkmap was called with an argument other than top that will be used instead of top.)

exchangedown (C-a C-Down)

Exchange the window in the current frame with the window in the frame below the current frame.

exchangeleft (C-a C-Left)

Exchange the window in the current frame with the window in the frame left of the current frame.

exchangeright (C-a C-Right)

Exchange the window in the current frame with the window in the frame right of the current frame.

exchangeup (C-a C-Up)

Exchange the window in the current frame with the window in the frame above the current frame.

exec shell-command (C-a !)

Spawn a shell executing shell-command.

execa shell-command

Spawn a shell executing shell-command, without remembering the current frame, so that _NET_WM_PID declaring programs will be placed into the frame active when they open a window instead of the frame active when sdorfehs gets this command.

execf frame shell-command

Spawn a shell executing shell-command, showing _NET_WM_PID supporting programs in the given frame instead of the frame selected when this program is run.

fdump [screenno]

Output the defining data for all frames of the current screen, or for screen number screenno if this is specified.

focus (C-a Tab)

Focus the next frame.

focuslast

Switch to the last selected focus.

focusleft (C-a Left)

Switch to the frame to the left of the current one.

focusdown (C-a Down)

Switch to the frame beneath the current one.

focusright (C-a Right)

Switch to the frame to the right of the current one.

focusprev

Focus the previous frame.

focusup (C-a Up)

Switch to the frame above the current one.

frestore frames

Replace the current frames with the ones specified in frames in the format as generated by fdump.

fselect [frameno] (C-a f)

If an argument is supplied, switch to a frame given by number frameno.

If no argument is given, show a frame selector in each frame and wait for a key to be pressed. If the key matches an existing frame selector, this frame gets focused.

Frame selectors are by default the numbers starting with zero, but they can be changed by setting framesels.

getenv variable

Output the value of the environment variable variable.

getsel

Paste the current X Selection into the current window.

gravity [nw | w | sw | n | c | s | ne | e | se]

Change how in its frame the current window is aligned.

help [keymap]

If the optional parameter keymap is given, list all keybindings in this keymap, otherwise list all key bindings in keymap root.

hsplit [l/p | [-]pixels] (C-a S)

Split the current frame into left frame and a right frame. If no parameter is given, split in halves. If two numbers separated by a slash (‘/’) are given, the left one is l times the pth part and the right one (p - l) times the pth part of the prior width. Otherwise the right half is pixels wide or the left one is pixels wide, depending whether there is ‘-’ in front of the number or not.

inext

Like next but switch to the next window with the same resource class as the current one. (That means the next window belonging to the same application as the current one.)

info (C-a i)

Output the current the width, height, window number and window name of the current window. (What name means is chosen by “set winname”.)

iprev

Like prev but switch to the previous window with the same resource class as the current one. (That means the previous window belonging to the same application as the current one.)

iother

Like other but switch to the window of the current vscreen that was last accessed and has the same resource class but is not currently visible.

kill (C-a K)

Close the X-connection of the X-client responsible for the current window.

lastmsg (C-a m)

Reshow the last message.

link key [keymap]

Do what key is bound to in the keymap keymap if supplied. Otherwise what key is bound to in keymap root.

listhook event

List all commands specified with addhook to be executed when even event occurs.

meta [key] (C-a t)

Send the escape key (that which normally is C-a) to the current window. If a key is specified, this is sent instead. Note that some applications by default ignore the synthetic key that is sent using this command as it is considered a security hole. xterm is one such application.

newkmap keymap

Generate a new keymap named keymap. This keymap can be used to add new key-command mappings to it with definekey and can be called with readkey.

next (C-a Return | C-a n | C-a space)

Switch to the next window in the current vscreen.

nextscreen (C-a N)

Switch to the next screen. (If you have multiple physical ones.)

number new [old]

Give the number new to the window with the number old or the current window.

only (C-a Q)

Remove all frames on the current screen except the current frame and maximize this one to the size of the whole screen.

other (C-a C-a)

Switch to the window of the current vscreen that was last accessed but is not currently visible.

prev (C-a p)

Switch to the previous window in the current vscreen.

prevscreen (C-a P)

Switch to the previous screen. (If you have multiple physical ones.)

prompt [prompt]

sdorfehs will ask the user for input, showing prompt (or a single colon, if no argument is given) and output the input the user has made. Note that this command probably does not make much sense in interactive mode.

putsel x-selection

Replace the X selection with the text x-selection. It can be inserted into the current window with getsel.

quit

Quit sdorfehs.

ratinfo

Display the x y coordinates of the rat cursor relative to the screen.

ratrelinfo

Display the x y coordinates of the rat cursor relative to the current window or current frame if no window is focused

ratwarp x y

Move the rat cursor to the position (x, y).

ratrelwarp deltax deltay

Move the rat cursor to (deltax, deltay), relative to the current position.

ratclick [button]

Simulate a rat click with button (button 1=left button if none given).

rathold (up | down) [button]

Simulate pressing|releasing rat button button (1=left button if none given).

readkey keymap

Grab the next key pressed, and execute the command associated to this key in keymap. To show it is waiting for a key, sdorfehs will change the rat cursor to a square if waitcursor is set. This command is perhaps best described with its usage in the default configuration: by pressing C-a, which is the only key in the keymap top , the command “readkey root” is executed. The next key then executes the command in keymap root belonging to this command.

redisplay (C-a l)

Extend the current window to the whole size of its current frame and redisplay it. (Useful to redisplay normal windows or bring transient windows to the full size of the frame as only normal windows are maximized by sdorfehs)

redo (C-a U)

Revert the last undo of frame changes.

remhook event command

Remove command command from the list of commands to be called when event event is hit. (The command has to specified, as an event can have multiple commands attached to it.) Use “listhook hook” to get a list of all attached commands.

remove (C-a R)

Remove the current frame and extend some frames around to fill the remaining gap.

resize [deltax deltay] (C-a r)

If deltax and deltay are supplied, resize the current frame by that (i.e. move the bottom right corner by the given offsets and then move this frame and resize adjacent frames to make the frames fill the whole screen again.)

If in interactive mode no arguments are supplied, resize the current frame interactively:

Return

finish resizing

C-g, Escape

abort resizing

C-n, Down, j

grow vertically

C-p, Up, k

shrink vertically

C-f, Right, l

grow horizontally

C-b, Left, h

shrink horizontally

s

shrink to size of current window

While resizing interactively, changes are in multiples of the amount of pixels given by set resizeunit (by default 10).

restart

Restart sdorfehs.

sdump

Output the list of all screens. The screens are separated by commas. Each screen is shown as 6 values: its number, its x-coordinate, its y-coordinate, its width, its height and if it is currently selected (1=true, 0=false).

select (- | name | number) (C-a ')

If a number is given, switch to the window with number number. If a name is given, switch to the window in the current vscreen with name name. Blank the current frame, if - is given.

set [variable [value]]

If no argument is given, output all sdorfehs variables and their values.

If one argument is given, output the value of sdorfehs variable variable. Otherwise set variable to value. What values are valid depends on the variable. See the section VARIABLES later in this document for details.

setenv variable value

Set the environment variable variable to value. (Environment variables will be passed to all programs started from sdorfehs.)

sfdump

Output all frames similar to fdump, but not limited to one screen, but all screens at once and with the screen number after each frame.

sfrestore frames

Replace the current frames with the ones specified in frames in the format as generated by sfdump.

shrink

Shrink the current frame to the size of the current window with in.

split [split] (C-a s)

alias for vsplit

source file

Read file and execute each line as sdorfehs command.

sselect screennumber

Switch to the screen screennumber. (If you have multiple physical ones.)

smove [screen]

Move the current window to the current frame and vscreen on screen screen and focus it.

stick

Mark the current window as sticky in its current frame, making it unavailable to other frames when selecting an available window.

swap dest-frame [src-frame] (C-a x)

Exchange the window in src-frame (or the current frame if there is no second argument) with the window dest-frame (or ask interactively which frame to swap with if there is no argument).

title newname (C-a A)

Overwrite the title of the current window with newname. All following sdorfehs commands will only know the window under the new name.

unalias alias

Remove the alias alias.

unbind key

alias for

undefinekey root key

undefinekey keymap key

Remove the binding for key from keymap.

undo (C-a _, C-a u)

Un-do the last change to the frameset. (Like splitting, resizing, deleting, ...)

The amount of steps that can be undone is specified by the variable maxundos.

unmanage [name]

Add name to the list of unmanaged windows. Thus, windows of this name will not be managed but allowed to choose their position themselves.

In non-interactive mode calling it without arguments will print the list.

The list can be cleared again by calling clrunmanaged.

unsetenv variable

Remove variable variable from the list of environment variables.

unstick

No longer consider the current window as sticky in its current frame, making it again available to appear in other frames.

verbexec cmdline

Spawn a shell executing cmdline after showing a message with the command.

vselect vscreen

Select the vscreen named vscreen.

vsplit [l/p | pixels-from-top | -pixels-from-bottom] (C-a s)

Split the current frame into upper frame and a lower frame. If no parameter is given, split in halves. If two numbers separated by a slash (“/”) are given, the upper one is l times the pth part and the lower one (p - l) times the pth part of the prior height. Otherwise the lower one is pixels from bottom wide or the upper one pixels from top high, depending whether there is a “-” in front of the number or not.

windows [format] (C-a w)

In interactive mode, show the list of all windows in the current vscreen for the duration specified by the variable msgwait. If msgwait was zero, toggle between indefinitely showing and not showing.

The messages are shown in columns or rows depending on the value of winliststyle in the format set by set winfmt. The following substitutions happen in format:

%a

application name (resource name)

%c

resource class

%f

frame number

%g

gravity of the window

%h

height of the window

%H

unit to resize the window vertically (height_inc)

%i

X Window ID

%p

process ID

%l

last access number

%M

string Maxsize, if it specifies a maximum size

%n

window number

%s

window status (‘*’ is active window, ‘+’ would be chosen by other, ‘-’ otherwise)

%S

screen number

%t

window name (see set winname),

%T

the string “Transient”, if it is a transient window

%w

width of the window

%W

unit to resize the window horizontally (width_inc)

%x

xrandr screen number

%%

litteral ‘%’

Additionally there can be a positive decimal integer number between the percent sign and the format string to specify the length this value should be truncated to if longer. (For example: %20t)

In non-interactive mode, output the list of windows in the current vscreen line by line. The format string can be overwritten by the optional parameter format.
