@chapter Introduction
StumpWM is a manual, tiling X11 window manager written entirely in
Common Lisp. Unlike traditional window managers, StumpWM places
windows in order to maximize the amount of the screen used. The
window layouts managed by StumpWM are defined by the user in much the
same way that windows are managed by GNU screen, or emacs.
Before StumpWM, there was ratpoison, another tiling window manager
written entirely in C. StumpWM grew out of the authors' frustration
with writing ratpoison in C. Very quickly we realized we were building
into ratpoison lispy-emacs style paradigms. StumpWM's goals are
similar to ratpoison's but with an emphasis on customizability,
completeness, and cushiness.

@section Starting StumpWM
There are a number of ways to start StumpWM but the most straight
forward method is as follows. This assumes you have a copy of the
StumpWM source code and are using the @samp{SBCL} Common Lisp
environment.
@enumerate
@item
Install the prerequisites and build StumpWM as described in
@file{README}. This should give you a @file{stumpwm} executable.
@item
In your @file{~/.xinitrc} file include the line
@command{/path/to/stumpwm}. Remember to replace @samp{/path/to/}
with the actual path.
@item
Finally, start X windows with @command{startx}. Cross your
fingers. You should see a @samp{Welcome To the Stump Window Manager}
message pop up in the upper, right corner. At this point, you have
successfully started StumpWM.
@end enumerate
@node Basic Usage, Basic Concepts, Starting StumpWM, Introduction
@section Basic Usage
Once you have StumpWM up and running, the first thing you might want
to do is start @command{emacs}. Type @kbd{C-t e}, or in other words
@kbd{Control + t} followed by @kbd{e}. Now perhaps you want an
@command{xterm}. Type @kbd{C-t c}. Now you have some programs running.
To see a list of windows StumpWM is managing, type @kbd{C-t w}. The
highlighted window is the one you're looking at right now. It's the
focused window.
All of StumpWM's keys are bound to named commands, which can be
executed not only by keys but also from the input bar. Type @kbd{C-t
;} to open a command prompt. Now type @command{time} and press
return. Note, @command{time} can also be called by typing @kbd{C-t a}.
Throughout this manual you'll find definitions for commands,
functions, and variables. Any command you see in this manual can be
executed from the input bar or bound to a key.
At this point you probably want to switch back from your new
@command{xterm} to @command{emacs}. Type @kbd{C-t C-t}. This runs the
@command{other} command. Type it again and you're back to xterm.
Perhaps you'd like to see @command{emacs} and @command{xterm}
side-by-side. Type @kbd{C-t s}. You have now split the screen into 2
@command{frames}. For more information see @ref{Frames}. To switch to the
empty frame type @kbd{C-t TAB}. Now let's pull the xterm window into
this empty frame. Type @kbd{C-t w} for a window listing. Find the
@command{xterm} window. See the number beside it? Type @kbd{C-t} followed
by @command{xterm}'s window number.
Another common activity is browsing the internet. Type @kbd{C-t !}.
The input bar pops up again. You can now run a shell command. Let's
start a web browser: type @command{firefox} into the input bar and press
return.
Unfortunately, @command{firefox} probably isn't wide enough because it's
in one of the frames. Type @kbd{C-t Q} to remove all frames but the
current one and resize it to fit the screen.
For a full list of key bindings, see @ref{List of Default Keybindings}.

@node Screens and Heads, Group Basics, Basic Concepts, Basic Concepts
@subsection Screens and Heads
A screen is an Xlib concept representing a section of video memory
onto which physical monitors, called ``heads'', are mapped. A screen can
be thought of as an abstract rectangle containing all the heads
arranged in a particular layout.
With most modern systems, you'll only have a single screen no matter
how many heads are connected to your computer. Each head will have its
own frame, and you can move between heads using the normal frame
movement commands.
The layout of the heads within the screen can be specified in one of two
ways: either at startup using your system's Xorg configuration files, or
on the fly using tools like XRandR. If the computer is booted with
multiple monitors attached, but without specifying a layout for them,
they will all show identical output.
StumpWM will attempt to detect the layout of the heads once at
startup, or any time a RandR command is issued.
In rarer setups you may have multiple screens, with one head per
screen. That means that you'll move between heads using screen
movement commands (`snext', `sprev', and `sother') rather than frame
movement commands.
@node Group Basics, Floating Group Basics, Screens and Heads, Basic Concepts
@subsection Group Basics
A group is usually referred to as a ``desktop'' or ``workspace'' in other
window managers. StumpWM starts with a single group, called ``Default''.
Each group has its own configuration of frames and windows that is
separate from and independent of other groups. You can't have
different groups display in different monitors: when you switch
groups, all monitors switch to that group.
Each group contains an ordered list of frames.
@node Floating Group Basics, Frame Basics, Group Basics, Basic Concepts
@subsection Floating Group Basics
Within a floating group, windows behave more like they do in traditional
window managers: rather than being arranged into frames, they each have
their own box, which can be freely resized and repositioned, and allowed
to overlap. Each window has a thicker border at the top. Left click in
this border and drag to move the window, or right click and drag to
resize it.
Most of the window-switching commands listed below do not function in
a floating group. You're restricted to `other', the `select-window-*'
commands, and `windowlist'.
@node Frame Basics, Window Basics, Floating Group Basics, Basic Concepts
@subsection Frame Basics
Frames are the boxes within which windows are displayed. StumpWM
starts with a single frame per head, meaning that each monitor shows a
single window, full screen. If you want to see windows side-by-side,
you can ``split'' this frame in two, either vertically or horizontally.
These frames can be further split, creating nested boxes.
Technically speaking, frames live within a ``frame tree''. When you
split a frame, the command actually creates @emph{two} new frames
side-by-side within the original parent frame. This makes no practical
difference, unless you use the `sibling' command, which will move to
the other child frame within the parent frame.
Within this frame tree model, all frames either contain other frames,
or windows. The command `fclear' will hide all a frame's windows and
show the background.
@node Window Basics, System Trays and the Mode Line, Frame Basics, Basic Concepts
@subsection Window Basics
Windows are created by programs to display their output. They take the
shape of the frame in which they are created. The windows within a
frame are ordered by how recently that window was focused. Only the
top window in the stack is visible.
@node System Trays and the Mode Line, , Window Basics, Basic Concepts
@subsection System Trays and the Mode Line
Many users choose to sacrifice a little screen real-estate to display
some generally useful information: the current time and date, wireless
network connections, the names of open windows, etc. StumpWM allows
you to display this information in a bar across either the top or the
bottom of the screen. There are two ways to do this: using external
programs called system trays, or using StumpWM's own mode line.
System trays are a special kind of X window. They advertise to running
programs that they are available for embedding icons or notifications
from those programs. They often also display clickable icons for each
open window. Common tray programs include the GNOME panel or KDE's
kicker, or simpler programs such as stalonetray. Simply starting one
of these programs is usually enough for StumpWM to detect it, place it
correctly, and allow it to function normally.
The mode line, a concept borrowed from Emacs, is a built-in part of
StumpWM. It is essentially a string of text that can include a variety
of information about your current session, including the names of
current groups and windows. Several modules provide for
different types of information. @xref{Mode-line, Mode Line}, (and the modules
directory) for more.
@node Manipulating Frames and Windows, Interacting with the Lisp process, Basic Concepts, Introduction
@section Manipulating Frames and Windows
Frames and windows are concepts borrowed from Emacs and the GNU Screen
program, and should be familiar to users of those programs. Others may
find the terms a little confusing. In other window managers, a
``window'' usually refers to a bounded box on the screen, showing output
from a single program. StumpWM splits this into two concepts: the
``frame'' is the bounded box, the ``window'' is the visible output of a
program.
One frame can contain many windows. As new windows are created, they
appear at the top of the window-stack of the current frame. This is
also a little different from other tiling window managers, many of
which automatically create new frames for new windows.
Both frames and windows are ordered by when they were last focused. In
the following commands and documentation, the terms ``next'' and
``previous'' refer to this order. ``Other'' refers to the most-recently
focused object. Calling ``other'' commands multiple times will bounce
back and forth between the two most recent objects.
By default, StumpWM starts with a single group, called ``Default'',
which contains one full-screen frame per head. You can split individual
frames horizontally or vertically using the `hsplit' and `vsplit'
commands, bound to ``C-t S'' and ``C-t s'' by default. When a frame is
split, the next-most-recently-focused window is pulled into the new
frame. @xref{Frames}, and @ref{Windows}, for a complete listing of
commands.

* Manipulating Windows::
@end menu
@node Moving Between Frames, Manipulating Windows, Manipulating Frames and Windows, Manipulating Frames and Windows
@subsection Moving Between Frames
Once you have multiple frames, you can move between them in various
ways:
@itemize
@item
@command{fnext} (@kbd{C-t o} or @kbd{C-t TAB}) jumps to the next frame in
the current group's frame list.
@item
@command{fother} (@kbd{C-t M-TAB}) jumps to the last frame that had
focus.
@item
@command{fselect} (@kbd{C-t f}) displays numbers on each visible frame: hit a
number key to move to that frame.
@item
@command{move-focus} (@kbd{C-t <arrow key>}) focus the frame in the direction of
the arrow key pressed.
@item
@command{sibling} (unbound by default) focus the frame from which the
current frame was split.
@end itemize
@node Manipulating Windows, , Moving Between Frames, Manipulating Frames and Windows
@subsection Manipulating Windows
Some commands change which window is currently focused, some move
windows between frames, and some may do both at once.
There are two general ways to move focus between windows: either
between windows belonging to the current frame, or between all windows
within the current group. Within a single frame:
@itemize
@item
@command{next-in-frame} (@kbd{C-t C-M-n}) focus the next window in the current
frame's list of windows.
@item
@command{prev-in-frame} (@kbd{C-t C-M-p}) focus the previous window in the
current frame's list of windows.
@item
@command{other-in-frame} (@kbd{C-t M-t}) focus the most recently focused window
in the current frame's list of windows.
@item
@command{frame-windowlist} (unbound by default) display a menu of windows in
the currently-focused frame, and allow the user to choose one.
Alternately, the command @command{frame-windows} will simply display the
list of window names, with no menu choice available.
@end itemize
Within the current group, the following commands will go straight to
the specified window. They will never move a window from its original
frame, and so may result in focus switching frames.
@itemize
@item
@command{next} (@kbd{C-t M-n}) focus the next window in the current group.
@item
@command{prev} (@kbd{C-t M-p}) focus the previous window in the current group.
@item
@command{other} or @command{other-window} (unbound by default) focus the
most recently focused window in the current group.
@item
@command{next-urgent} (@kbd{C-t C-u}) focus the next window that has marked
itself ``urgent''.
@item
@command{select} or @command{select-window} (@kbd{C-t '}) prompt for the
title of a window and focus it. Works with partial completion of the
title.
@item
@command{select-window-by-name} (unbound by default) prompt for the
title of a window and focus it. Requires the window title to be entered
exactly.
@item
@command{select-window-by-number} (@kbd{C-t <number>}) choose a window by
number.
@item
@command{windowlist} (``C-t "") display a menu of windows in the
currently-focused group, and allow the user to choose one.
@end itemize
The following commands always keep the current frame focused. If the
selected window is not in the current frame, it will be pulled there
from wherever it is (hence the ``pull'' naming scheme).
@itemize
@item
@command{pull} or @command{pull-window-by-number} (@kbd{C-t C-<number>})
pull the numbered window into the current frame.
@item
@command{pull-hidden-next} (@kbd{C-t n} or @kbd{C-t SPC}) pull the next
currently undisplayed window in the window list into the current frame.
@item
@command{pull-hidden-previous} (@kbd{C-t p}) pull the previous currently
undisplayed window in the window list into the current frame.
@item
@command{pull-hidden-other} (@kbd{C-t C-t}) pull the most recently
focused, currently undisplayed window into the current frame.
@end itemize
The following commands move the current window from one frame to
another, bringing focus with them.
@itemize
@item
@command{move-window} (@kbd{C-t M-<arrow>}) move the currently focused
window in the direction indicated by the arrow key.
@item
@command{exchange-direction} (unbound by default) prompt for a
direction, then swap the currently focused window with the top window of
the frame in that direction.
@end itemize
@node Interacting with the Lisp process, Init File, Manipulating Frames and Windows, Introduction
@section Interacting with the Lisp process
Since StumpWM is a Lisp program, there is a way for you to evaluate
Lisp code directly, on the same Lisp process that StumpWM is running on.
Type @kbd{C-t :} and an input box will appear. Then type some Lisp
expression.
When you call @command{eval} this way, you will be in the STUMPWM-USER
package, which imports all the exported symbols from the main STUMPWM
package.
@table @code
@item *mode-line-border-width*
Reads the value of @var{*mode-line-border-width*}.
@item (setf *mode-line-border-width* 3)
Sets the variable @var{*mode-line-border-width*} to 3.
@item (set-prefix-key (kbd "C-M-H-s-z"))
Calls the @code{set-prefix-key} function (and sets a new keyboard prefix)
@end table
@node Init File, Contact the StumpWM developers, Interacting with the Lisp process, Introduction
@section Init File
Like other window managers, StumpWM's configuration and startup
state can be controlled by an initialization file. Unlike other
window managers, StumpWM's init is not limited to changing settings
and keybindings. The init file is itself a Common Lisp program
running in a Common Lisp environment, so you can write your own
hacks and make them a part of your StumpWM experience.
On launch, StumpWM searches for an init file of different names and
locations on your system, and will use the first one found in this
order:
@itemize
@item `~/.stumpwmrc' is the classic UNIX-style configuration name;
@item `~/.stumpwm.d/init.lisp' is an Emacs-style location and name;
@item `~/.config/stumpwm/config' is the XDG standard;
@item `/etc/stumpwmrc' is a system-wide file giving all users a
standardized environment.
@end itemize
StumpWM includes a basic `sample-stumpwm.lisp' in its source
directory. You can use this as a template when you're starting out:
copy it to the above name and location you prefer and edit it to
suit your preferences.
It is possible to split your initialization among multiple files,
if you call the additional files from within an init file matching
the names and locations listed above.

@item C-t e
@itemx C-t C-e
Run Emacs or raise it if it is already running.
@item C-t t
Sends a @kbd{C-t} to the frame; this is useful for applications like Firefox
which make heavy use of @kbd{C-t} (in Firefox's case, for opening a new
tab). This is similar to how GNU screen uses @kbd{C-a a}.
@item C-t w
@itemx C-t C-w

@section Modifiers
Many users have had some difficulty with setting up modifiers for
StumpWM keybindings. This is caused by a combination of how StumpWM
handles modifiers and the default modifiers list for many users' X
servers.
@itemize
@item
My ``Super'' key doesn't work!
This is most likely caused by having the Hyper and Super keys listed
as the same modifier in the modifier list.

lock Caps_Lock (0x42)

mod3
mod4 Super_L (0x7f), Hyper_L (0x80)
mod5 Mode_switch (0x5d), ISO_Level3_Shift (0x7c)
@end example
The problem is in the line beginning with ``mod4''. The way to set up
the modifier list correctly is to have just the Super key as the mod4
modifier. The following @command{xmodmap} commands will do just that.
@example
# clear out the mod4 modifier
$ xmodmap -e 'clear mod4'
$ xmodmap
xmodmap: up to 3 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x6d)
mod1 Alt_L (0x40), Alt_R (0x71), Meta_L (0x9c)
mod2 Num_Lock (0x4d)
mod3
mod4
mod5 Mode_switch (0x5d), ISO_Level3_Shift (0x7c)
# add Super as a mod4 modifier
$ xmodmap -e 'add mod4 = Super_L'
$ xmodmap
xmodmap: up to 3 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x6d)
mod1 Alt_L (0x40), Alt_R (0x71), Meta_L (0x9c)
mod2 Num_Lock (0x4d)
mod3
mod4 Super_L (0x73), Super_L (0x7f)
mod5 Mode_switch (0x5d), ISO_Level3_Shift (0x7c)
@end example
You can automate this by storing the commands in a file and calling
xmodmap when you start your X session.
@example
$ cat ~/.Xmodmap
clear mod4
add mod4 = Super_L
@end example
If you use @command{startx}, modify your @file{~/.xsession} or @file{~/.xinitrc} file.
@example
$ cat ~/.xsession
#!/bin/sh
xmodmap ~/.Xmodmap
exec /usr/bin/stumpwm
@end example
If you use a settings daemon from one of the major desktop
environments (Gnome,KDE, or Unity) you may be able to set keyboard
modifiers from their respective configuration GUIs. If not,
@command{xmodmap} should always work if invoked at the right place.
@item
Handling Meta and Alt: when do I use @kbd{M-} and @kbd{A-}?
If you have no Meta keys defined (see the output of the @command{xmodmap}
command), then StumpWM will treat the @kbd{M-} prefix in keybindings to
mean Alt. However, if there are Meta keys defined, then the @kbd{M-}
prefix refers to them, and the @kbd{A-} prefix refers to Alt.
Most users will simply use @kbd{M-} to refer to their Alt keys. However,
users that define separate Meta and Alt keys will use @kbd{M-} to refer
to the former, and @kbd{A-} to refer to the latter.
@item
How can I set up a Hyper key and use it with StumpWM?
To set up a Hyper key, you need to do two things: bind a physical key
to be a Hyper key, and add that key to the modifiers list.
The following example shows how to bind the control key at the
bottom-left of most keyboards to be Hyper. This is useful if you've
made Caps Lock into a control key, and have no use for the bottom-left
key.
@example
$ xmodmap -e 'keycode 37 = Hyper_L'
$ xmodmap -e 'clear mod5'
$ xmodmap -e 'add mod5 = Hyper_L'
@end example
To use a different key for Hyper, replace the keycode ``37'' above.
Use the @command{xev} program to see the keycode that any physical key has.
Refer to the section above on setting up the Super key to see how to
automate setting the Hyper key when you start X.
Now you can use @kbd{H-} as a prefix in StumpWM bindings.
@example
(define-key *top-map* (kbd "H-RET") "fullscreen")
(define-key *top-map* (kbd "H-Left") "gprev")
(define-key *top-map* (kbd "H-Right") "gnext")
(define-key *top-map* (kbd "H-TAB") "other")
@end example
Since essentially no programs have Hyper bindings, you can safely bind
commands to the @var{*top-map*}.
@end itemize
@node Commands, Message and Input Bar, Key Bindings, Top
@chapter Commands
If you've used Emacs before you'll find the distinction between
commands and functions familiar. Commands are simply functions that
can be bound to keys and executed interactively from StumpWM's input
bar. Whereas, in Emacs, the special "(interactive)" declaration is
used to turn a function into a command, in StumpWM commands are made
with a separate @command{defcommand} macro.
Once a command is defined, you can call it by invoking the
@command{colon} command (@kbd{C-t ;}), and typing the name
of the command. This may be sufficient for commands that aren't used
very often. To see all the currently-defined commands, invoke the
command called @command{commands}: ie press @kbd{C-t ;},
type ``commands'', and hit return.
Commonly-used commands can also be bound to a keystroke, which is much
more convenient. To do this, use the @command{define-key}
function (see @ref{Key Bindings}), giving the name of the command as a
string. For example:
@example
(define-key *root-map* (kbd "d") "exchange-direction")
@end example
You cannot give the command name as a symbol, nor can you bind a key
to a regular function defined with @command{defun}.
If the command takes arguments (see @ref{Writing Commands}), you can fix
those arguments when defining the key-binding, by including the
arguments in the same string as the command name, separated by a
space. For instance, the @command{exchange-direction} command,
which is unbound by default, requires a direction in which to exchange
windows. If you call @command{exchange-direction} directly, it
will prompt you for the direction. If you know that you often exchange
in left/right directions, and want those actions bound to keys, you
can use the following in your customization file:
@example
(define-key *root-map* (kbd "[") "exchange-direction left")
(define-key *root-map* (kbd "]") "exchange-direction right")
@end example
Multiple arguments can be included by adding them to the command
string, separated by spaces. Not all argument types can be represented
as strings, but StumpWM will do its best to convert types.
StumpWM does not implement the Emacs concept of prefix arguments.

* Writing Commands::
* StumpWM Types::
@end menu
@node Writing Commands, StumpWM Types, Commands, Commands
@section Writing Commands
StumpWM commands are written much like any Lisp function. The main
difference is in the way command arguments are specified. The
@command{defcommand} macro takes a list of arguments as its first
form (similar to the @command{defun} macro), and a corresponding
list of types as its second form. All arguments must belong to a
``type''. Each type specification has two parts: a keyword specifying
the argument type, and a string prompt that will be displayed when
asking the user to enter the argument value. A typical
@command{defcommand} might look like this:
@example
(defcommand now-we-are-six (name age)
((:string "Enter your name: ")
(:number "Enter your age: "))
(message "~a, in six years you will be ~a" name (+ 6 age)))
@end example
If @command{now-we-are-six} is called interactively via the
@command{colon} command, the user will be prompted for a string
and a number, which will then be bound to ``name'' and ``age'',
respectively, in the body of the command.
When invoking the command via a key-binding, it is possible to provide
some or all of the arguments directly:
@example
(define-key *root-map* (kbd "L") "now-we-are-six John")
@end example
In this case, hitting @kbd{C-t L} will only prompt for an age (the first
string argument is already bound to ``John''). Argument values provided
this way always bind to the earliest arguments defined: ie, it is not
possible to specify an age, but prompt the user for a name.
If the type declaration does not include a prompt (ie, it looks like
``(:type nil)'', or ``(:type)'' or just ``:type''), the argument is
considered optional. It can be provided via a key-binding invocation, as
above, but if it isn't, the user will not be prompted, and the argument
will be bound to nil.
Lastly, it is possible to limit the scope under which the command will
be usable: a command can be defined to work only in tile groups, or only
in floating groups (the only two types of groups that currently exist).
This is done by replacing the name of the command with a two-element
list: the name of the command as a symbol, and either the symbol
tile-group or floating-group. For instance, the @command{next} command,
which only functions in tile groups, is defined this way:
@example
(defcommand (next tile-group) @dots{})
@end example
@node StumpWM Types, , Writing Commands, Commands
@section StumpWM Types
All command arguments must be of a defined ``StumpWM type''. The
following types are pre-defined:
@table @var
@item :y-or-n
A yes or no question returning T or NIL.
@item :variable
A lisp variable
@item :function
A lisp function
@item :command
A stumpwm command as a string.
@item :key-seq
A key sequence starting from *TOP-MAP*
@item :window-number
An existing window number
@item :number
An integer number
@item :string
A string
@item :key
A single key chord
@item :window-name
An existing window's name
@item :direction
A direction symbol. One of :UP :DOWN :LEFT :RIGHT
@item :gravity
A gravity symbol. One of :center :top :right :bottom :left :top-right :top-left :bottom-right :bottom-left
@item :group
An existing group
@item :frame
A frame
@item :shell
A shell command
@item :rest
The rest of the input yes to be parsed.
@item :module
An existing stumpwm module
@end table
Additional types can be defined using the macro
@command{define-stumpwm-type}. Emacs users who are accustomed to writing
more complicated interactive declarations using "(interactive (list
@dots{}))" forms will find that similar logic can be put into StumpWM
type definitions. The macro is called like this:
(define-stumpwm-type :type-name (input prompt)
body)
The keyword :type-name will then be available for use in
@command{defcommand} macros. When commands are called, the bodies
of these type definitions are called in turn to produce actual
argument values.
Type definitions produce their value in one of several ways: by
reading it from the argument line bound to a keystroke, by prompting
the user to enter a value, or by generating it programmatically.
Within the body of the type definition, the argument ``input'' is bound
to the argument line provided in the command string, and ``prompt'' to
the string prompt provided in the @command{defcommand} form. The
usual convention is to first check if an argument has been provided in
``input'' and, if it hasn't, to prompt for it using ``prompt''.
StumpWM provides several convenience functions for handling the value
of ``input'':
@itemize
@item
@command{argument-pop} (input) pop the next space-delimited
argument from the argument line.
@item
@command{argument-pop-rest} (input) return the remainder of the
argument line as a single string, leaving input empty
@item
@command{argument-pop-or-read} (input prompt &optional
completions) either pop an argument from the argument line, or if it
is empty use ``prompt'' to prompt the user for a value
@item
@command{argument-pop-rest-or-read} (input prompt &optional
completions) either return the remainder of the argument line as a
string, leaving input empty, or use ``prompt'' to prompt the user for
a value
@end itemize
As an example, here's a new type called :smart-direction. The
existing :direction type simply asks for one of the four directions
``left'', ``right'', ``up'' or ``down'', without checking to see if there's a
frame in that direction. Our new type, :smart-direction, will look
around the current frame, and only allow the user to choose a
direction in which another frame lies. If only one direction is
possible it will return that automatically without troubling the user.
It signals an error for invalid directions; it could alternately
return a ``nil'' value in those cases, and let the command handle that.
@example
(define-stumpwm-type :smart-direction (input prompt)
(let ((valid-dirs
(loop ; gather all the directions in which there's a neighbouring frame
with values = '(("up" :up)
("down" :down)
("left" :left)
("right" :right))
with frame-set =
(group-frames (window-group (current-window)))
for dir in values
for neighbour = (neighbour
(second dir)
(window-frame (current-window)) frame-set)
if (and neighbour (frame-window neighbour))
collect dir))
(arg (argument-pop input))) ; store a possible argument
(cond ((null valid-dirs) ; no directions, bail out
(throw 'error "No valid directions"))
(arg ; an arg was bound, but is it valid?
(or (second (assoc arg valid-dirs :test #'string=))
(throw 'error "Not a valid direction")))
((= 1 (length valid-dirs)) ; only one valid direction
(second (car valid-dirs)))
(t ; multiple possibilities, prompt for direction
(second (assoc (completing-read input prompt valid-dirs
:require-match t)
valid-dirs :test #'string=))))))
(defcommand smarty (dir) ((:smart-direction "Pick a direction: "))
;; `dir' is a keyword here
(message "You're going ~a" (string-downcase dir)))
(define-key *root-map* (kbd "R") "smarty right")

@section Window Selection Expressions
Window Selection Expressions (WSE) were inspired by SQL. The intent is
to allow writing consise code to select the windows you need and to
act upon them (or just to get the list of selected windows). The
implementation includes a set of (hopefully) consistent
consisely-named wrappers for the StumpWM functionality useful for
window set description and the act-on-matching-windows macro that
encapsulates the logic of iterating over a window set.
If we had SQL in StumpWM, we would write
@code{select window_id from windows as w where w.title = 'XTerm'}. WSE chooses to be
more Lisp-style and instead uses
@code{(act-on-matching-windows (w) (titled-p w "XTerm") w)}
The @code{act-on-matching-windows} function also allows performing some
actions, for example getting all the windows titled XTerm into the
current group:
@code{(act-on-matching-windows (w) (titled-p w "XTerm") (pull-w w))}

@chapter The Mode Line
The mode line is a bar that runs across either the top or bottom of
a head and is used to display information. By default the mode line
displays the list of windows, similar to the output @kbd{C-t w} produces.
Alternatively, external panel applications such as the GNOME panel and
KDE's kicker may be used. Simply starting one of these programs is enough
to set it as the mode line of the head it would like to be on (if the
panel is XRandR aware) or whichever head is available. In order to
avoid problems displaying menus, configure your panel application for
positioning at the top or bottom of the head rather than relying on
@var{*mode-line-position*}
The mode line can be turned on and off with the @command{mode-line}
command or the lisp function @code{stumpwm:toggle-mode-line}. Each
head has its own mode line. For example:
@example
;; turn on/off the mode line for the current head only.
(stumpwm:toggle-mode-line (stumpwm:current-screen)
(stumpwm:current-head))
@end example
The mode line is updated after every StumpWM command.
To display the window list and the current date on the modeline, one
might do the following:
@example
(setf stumpwm:*screen-mode-line-format*
(list "%w | "
'(:eval (stumpwm:run-shell-command "date" t))))
@end example
@code{(stumpwm:run-shell-command "date" t)} runs the command
@command{date} and returns its output as a string.

StumpWM will attempt to detect external monitors (via @code{xdpyinfo})

head. Heads are logically contained by screens. In a dual-monitor
configuration, there will be one screen with two
heads. Non-rectangular layouts are supported (frames will not be
created in the 'dead zone'.) And message windows will be displayed on
the current head--that is, the head to which the currently focused
frame belongs.
In addition, StumpWM listens for XRandR events and re-configures the
heads to match the new monitor configuration. Occasionally StumpWM
will miss an XRandR event, use @code{refresh-heads} to synchronize
the head configuration.

@section Sending a Bug Report
While StumpWM's code-base is quite mature, it still contains some
bugs. If you encounter one here are some guidelines for making sure
the developers can fix it:
@itemize @bullet
@item
Include a procedure for reproducing the bug/bad behavior. Ideally this
will include numbered steps starting with instructions on how you
start stumpwm. Also include what the expected behavior was.
@item
Be as detailed as possible. Then add more detail!
@item
Make sure its not something you introduced by using an empty @file{.xinitrc}
containing only 'exec /path/to/stumpwm'.
@item
Make sure the bug is present even when @file{.stumwmrc} is empty.
@item
If you are using the git version, include the hash of the master
branch, or better include the commit when you started to notice the
bug.
@item
If you have code that fixes the bug, then open a pull request at
@url{https://github.com/stumpwm/stumpwm/compare/}.
@item
If you don't have code to fix the bug, then open an issue at
@url{https://github.com/stumpwm/stumpwm/issues/new}.

@chapter Colors
When specifying a color, it is possible to use its X11 Color Name
(usually in the file @file{/etc/X11/rgb.txt}). You can also use a
six digit hex string prefixed by a '#' character in the same way that
you can specify colors in HTML.
All text printed by stumpwm is run through a coloring engine before
being displayed. All color commands start with a @samp{^} (caret)
character and apply to all text after it.
@table @code
@item ^0-9
A caret followed by a single digit number changes the foreground color
to the specified color. A @samp{*} can be used to specify the normal
color. See the color listing below.
@item ^0-90-9
A caret followed by two digits sets the foreground and background
color. The first digit refers to the foreground color and the second
digit to the background color. A @samp{*} can be used in place of
either digit to specify the normal color. See the color listing below.
@item ^B
Turn on bright colors.
@item ^b
Turn off bright colors.
@item ^n
Use the normal background and foreground color.
@item ^R
Reverse the foreground and background colors.
@item ^r
Turn off reverse colors.
@item ^[
Push the current colors onto the color stack. The current colors remain unchanged.
@item ^]
Pop the colors off the color stack.
@item ^>
Align the rest of the line to the right of the window.
@item ^f<n>
Sets the current font to the font at index n in the screen's font list.
@item ^(<modifier> &rest arguments)
Allows for more complicated color settings:
<modifier> can be one of :fg, :bg, :reverse, :bright, :push, :pop, :font and :>.
The arguments for each modifier differ:
@itemize
@item
:fg and :bg take a color as an argument, which can either be a numeric
index into the color map or a hexadecimal color in the form of "#fff"
or "#ffffff".
@item
:reverse and :bright take either t or nil as an argument. T enables
the setting and nil disables it.
@item
:push and :pop take no arguments. :push pushes the current settings onto
the color stack, leaving the current settings intact. :pop pops color
settings off the stack, updating the current settings.
@item
:font takes an integer that represents an index into the screen's
list of fonts, or, possibly, a literal font object that can
immediately be used. In a string you'll probably only want to specify
an integer.
@item
:> takes no arguments. It triggers right-alignment for the rest of the line.
@end itemize
@item ^^
Print a regular caret.
@end table
The default colors are made to resemble the 16 VGA colors and are:
@table @asis
@item 0 black

StumpWM exports a number of hooks you can use to add customizations;
like hooks in Emacs, you add to a hook with the @code{add-hook}
function. for example:
@example
(stumpwm:add-hook 'stumpwm:*new-window-hook* 'my-new-window-custos)
@end example
adds your @code{my-new-window-custos} function to the list of
functions called when a new window appears.

@node Modules, Hacking, Hooks, Top
@chapter Modules
A module is a ASDF system that adds additional functionality to
StumpWM. StumpWM searches for modules in the
@var{*data-dir*}@file{/modules} directory. By default this is
@file{~/.stumpwm.d/modules}.
Officially supported modules exist in a separate repository within the
StumpWM organization on github. You can install the latest copy by
issuing @command{make install-modules} from StumpWM's root source
directory. This will run:
@example
git clone git@@github.com:stumpwm/stumpwm-contrib.git ~/.stumpwm.d/modules
@end example
!!! load-module
@@@ list-modules

!!! add-to-load-path
@@@ init-load-path

@menu
* Writing Modules::
@end menu
@node Writing Modules, , Modules, Modules
@section Writing Modules
Make sure to read @ref{Hacking}. If you are familiar with writing lisp
packages for ASDF then you can jump in and get started. In either
case, quicklisp ships a @code{quickproject} package that makes setting
up a new module very easy. After installing quicklisp (see the
README.md for a link):
We're going to put our new module in the @file{modules/} directory of
@var{*data-dir*} so that it will be immediately loadable by stumpwm.
First make the directory @file{new-module}, then from a REPL issue:
@example
(ql:quickload "quickproject")
(quickproject:make-project #p"~/.stumpwm.d/modules/new-module" :depends-on '(stumpwm) :name "new-module")
@end example
This will create:
@example
-rw-rw-r-- 1 dave dave 68 Apr 6 19:38 package.lisp
-rw-rw-r-- 1 dave dave 53 Mar 16 2014 README.txt
-rw-rw-r-- 1 dave dave 271 Mar 16 2014 new-module.asd
-rw-rw-r-- 1 dave dave 1.8K Apr 6 17:51 new-module.lisp
@end example
The file @file{new-module.lisp} will contain the actual implementation
of your module. ASDF requires two other files in order to understand
how to load and compile your module. They are @file{new-module.asd}
and @file{package.lisp}. In our example, @file{new-module.asd} should
contain:
@example
(asdf:defsystem #:new-module
:serial t
:description "Describe new-module here"
:author "Anne N. O'Nymous"
:license "GPLv3"
:depends-on (#:stumpwm)
:components ((:file "package")
(:file "new-module"))) ; any other files you make go here
@end example
The @file{package.lisp} will contain:
@example
(defpackage #:new-module
(:use #:cl :stumpwm))
@end example
With these two files defined, and the implementation written in
@file{new-module.lisp}, you should be able to load your module.
Before we load it, we have to add the path to our @var{*load-path*}.
This can be accomplished by running the following from a REPL:
@example
(stumpwm:add-to-load-path "~/.stumpwm.d/modules/new-module")
@end example
You can also run this interactively with @kbd{C-t ;}, which is bound
to the @command{colon} command.
Because we've put our module in a sub-directory of the default
@var{*module-dir*}, it will automatically get added to the
@var{*load-path*} the next time StumpWM starts. If you choose to
develop your module somewhere else (e.g.
@file{~/quicklisp/local-projects}), then you'll have add
@example
(add-to-load-path "~/quicklisp/local-projects/new-module")
@end example
to your @file{.stumpwmrc}.
When you've finished writing your module, you can distribute it
however you see fit. If it becomes very popular, or you would like
the StumpWM devs to maintain it (and they agree), you can have your
module merged with the stumpwm-contrib repository on github, just open
a pull request to start the discussion.

@node General Advice, Using git with StumpWM, Hacking, Hacking
@section Hacking: General Advice
@enumerate
@item
Pay attention to file names and contents. If you're making changes to
mode-line related code, don't put it in @file{core.lisp}. If you're
introducing some completely new featureset, consider putting all of
the new code in a new file.
@item
Does a command need to be user-visible (``interactive'') or is it just
called by other commands?
@itemize
@item
If it's not going to be user-visible, you can just use the familiar
@code{(defun foo () ...)} syntax.
@item
If you want the command to be used interactively, you use StumpWM's
@code{defcommand} syntax, as in the examples below.
@example
(defcommand test (foo bar)
((:string "How you're going to prompt for variable foo: ")
(:number "How you want to prompt for variable bar: "))
"This command is a test"
(body...))
(defcommand test2 () ()
"This is also a test"
(body...))
(defcommand title (args) (interactive-args)
"Doc string"
(body...))
@end example
So basically, inside the first set of parentheses after the
function name, you specify what (if any) arguments will be passed to
the command. The second set of parentheses tells StumpWM how to get
those arguments if they're not explicitly passed to the command. For
example,
@example
((:string "What do you want to do: "))
@end example
will read a string from the input the user provides. The quoted
text is the prompt the user will see. Of course, if you were to, say,
call the command test, as defined above, from another piece of code,
it wouldn't give the prompt as long as you fed it arguments.
@end itemize
@item
Note that all commands defined using the @code{defcommand} syntax are
available both to be called with @kbd{C-t ;} and from within other lisp
programs, as though they had been defun-ned (which, in fact, they
have).
@item
Any code that depends on external libraries or programs that some
users might not have installed should be packaged as a module and
placed in the @file{*data-dir*/modules/} directory.
@item
Don't be afraid to submit your patches to the StumpWM mailing list!
It may not immediately make it into the official git repository, but
individual users might find it useful and apply it to their own setup,
or might be willing to offer suggestions on how to improve the code.
@item
Remember: StumpWM is designed to run on many lisp systems. If
you must use code specific to one or the other, at the very least warn
people that it only works with one lisp implementation. Better yet,
figure out how to do it in the other distribution and write a
statement like this:
@example
#+clisp
(your-clisp-code)
#+sbcl
(your-sbcl-code)
@end example
#to wrap the code for each lisp. Of course, the best option is to
find a way to use the same code for clisp and SBCL.
@end enumerate
@node Using git with StumpWM, Sending Patches, General Advice, Hacking
@section Hacking: Using git with StumpWM
For quite a while now, StumpWM has been using the git version control
system for development. If you're one using one of the official
releases, you can get the bleeding-edge source code from the official
git repository with a single command:
@example
$ git clone git@@github.com:stumpwm/stumpwm.git
@end example
After this, you'll have a complete git repository, along with the
complete revision history since the switch. Feel free to play around;
git has some important features that actually make this safe!
Before we get to that stuff, though, you're going to want to tell git
about yourself so that your information is included in your commits
and patches. The very minimum you're going to want to do is:
@example
$ git config --global user.name "Anne N. O'Nymous"
$ git config --global user.email "anonymous@@foo.org"
@end example
Be sure to check out the manual for @command{git-config}--there are several
options you might want to set, such as enabling colorized output or
changing the editor and pager you use when making commits and viewing
logs.
For the sake of argument, let's say you want to make some major
changes to both @file{user.lisp} and @file{core.lisp}, add a file called
@file{DANGEROUS_EXPERIMENT_DO_NOT_USE_OR_@-ELSE.lisp}, and remove the manual
because you're too 1337 for such things. However, you don't want to
break your entire StumpWM setup and start over. Thankfully, you don't
have to. Before you get started, issue this command from the stumpwm
directory:
@example
$ git checkout -b experimental
@end example
You should now find yourself in a new branch, called experimental. To
confirm this, type @command{git branch}; there should be
an asterisk next to the branch you're currently viewing. At any time,
you can type @command{git checkout master} to return to your master branch,
and at any time you can have as many branches of the project as you
like. If you want to create a new branch based not on the master
branch but on your experimental branch, for example, you'd type:
@example
$ git checkout -b new-experiment experimental
@end example
This will place you in a newly-created branch called ``new-experiment''
which should be identical to your experimental branch as of the last
commit (more on that soon). If you're actually typing out the
directions, switch back to your old experimental branch like so:
@example
$ git checkout experimental
@end example
Anyway, now that you have a new branch, create that new file with the
long name, which I'll just call @file{danger.lisp} for brevity. Make whatever
changes you want to it, and when you're done, tell git about your new
file.
@example
$ git add dangerous.lisp
@end example
Now, let's pretend you're done making changes. Tell git you're done
for now:
@example
$ git commit -a
@end example
This will open up a prompt in your editor of choice for you to
describe your changes. Try to keep the first line short, and then add
more explanation underneath (for an example, run the command @command{git log}
and take a look at some of the longer commit explanations). Save that
file and then do this:
@example
$ git checkout master
$ ls
@end example
Then look for your new file. It's not there! That's because you've
done all of your work in another branch, which git is currently hiding
from you so that you can ``check out'' the branch called ``master.'' All
is as it should be--your master repository is still safe.
@example
$ git checkout experimental
@end example
Now, delete @file{manual.lisp} and @file{stumpwm.texi}. That's right. Wipe them off
the face of the Earth, or at least off the hard drive of your
computer. When you're done, you don't have to tell git you've deleted
them; it'll figure it out on its own (though things may not compile
properly unless you edit @file{Makefile.in} and @file{stumpwm.asd}. Anyway, go ahead
and edit @file{core.lisp} and @file{user.lisp}. Really break 'em. Run free! When
you're done, do another commit, as above, and give it a stupid title
like ``lolz i b0rked stUmpwm guys wTF!?!?!!111!'' Now try to compile.
Just try. It won't work. If it does, you're some kind of savant or
something. Keep up the good work. If you've actually managed to break
StumpWM like you were supposed to, never fear! You have two options at
this point.
One is to go back to the master branch (with another git checkout) and
just delete your experimental branch, like so:
@example
$ git branch -D
@end example
The ``@code{-D}'' means to force a delete, even if the changes you've made
aren't available elsewhere. A ``@code{-d}'' means to delete the branch if and
only if you've merged the changes in elsewhere.
The other option is to create patches for each of your commits so far,
delete the branch, and then apply any working/wanted patches in a new
branch. Create your patches (after committing) like so:
@example
$ git format-patch -o patches origin
@end example
(Before doing that you can review your changes with @command{git log origin..})
You can also use the @command{format-patch} command to create a patch of working
code to send in to the mailing list.
A developer might ask you to try out something they're working on. To
fetch their master branch, you'd do this:
@example
$ git remote add -f -m master -t master foo git://bar.org/~foo/stumpwm
@end example
Here, ``foo'' is the shorthand name you'll use to refer to that
repository in the future. To checkout a local copy of that repository,
you'd then do
@example
$ git checkout --track -b foo-master foo/master
@end example
Later you could use @command{git pull foo} to update while looking at that
branch (and note that @command{git pull} with no arguments, in the master
branch, will update your StumpWM from the official repository).
Finally, if you want to move your experimental changes into your
master branch, you'd checkout your master branch and run:
@example
$ git merge experimental
@end example
If there are file conflicts, @command{git diff} will show you where they are;
you have to fix them by hand. When you're done, do another
@example
$ git commit -a
@end example
to finalize the changes to your master branch. You can then delete
your experimental branch. Alternately, you can wait until your changes
(assuming you sent them in) make it into the official repository
before deleting your experimental branch.
@node Sending Patches, , Using git with StumpWM, Hacking
@section Sending Patches
While patches are still welcome on the mailing list, StumpWM's
development has mostly migrated to github's issue tracker. This means
you can open a pull request to submit a patch to StumpWM. The
following guidelines apply to pull requests and patches sent to the
mailing list.
@itemize
@item
Make sure it applies clean to the main git repository
@item
Ensure that you aren't introducing tabs, extra blank lines, or whitespace at the end of lines.
@item
Ensure your patch doesn't contain irrelevant indenting or reformatting changes.
@item
Try to make your patch address a single issue. If your patch changes
two unrelated issues, break them into two seperate patches that can
stand on their own.
@item
Don't send intermediate patches. When you're working on a feature you
might make several commits to your local repository as you refine it
and work out the bugs. When it's polished and ready to ship, send it
as one patch! Sometimes it makes sense to send it as multiple patches
if each patch contains a discrete feature or bug fix that can stand on
its own. If one of your patches changes code that was added or
modified in an earlier patch, consider merging them together and
sending them as one.
