The function redraw-frame
redisplays the entire contents of a
given frame. @xref{Frames}.
This function clears and redisplays frame frame.
Even more powerful is redraw-display
.
This function clears and redisplays all visible frames.
Normally, suspending and resuming Emacs also refreshes the screen. Some terminal emulators record separate contents for display-oriented programs such as Emacs and for ordinary sequential display. If you are using such a terminal, you might want to inhibit the redisplay on resumption. @xref{Suspending Emacs}.
This variable controls whether Emacs redraws the entire screen after it
has been suspended and resumed. Non-nil
means yes, nil
means no.
Processing user input takes absolute priority over redisplay. If you call these functions when input is available, they do nothing immediately, but a full redisplay does happen eventually—after all the input has been processed.

The screen size functions report or tell Emacs the height or width of the terminal. When you are using multiple frames, they apply to the selected frame (@pxref{Frames}).
This function returns the number of lines on the screen that are available for display.
(screen-height) ⇒ 50
This function returns the number of columns on the screen that are available for display.
(screen-width) ⇒ 80
This function declares that the terminal can display lines lines. The sizes of existing windows are altered proportionally to fit.
If not-actual-size is non-nil
, then Emacs displays
lines lines of output, but does not change its value for the
actual height of the screen. (Knowing the correct actual size may be
necessary for correct cursor positioning.) Using a smaller height than
the terminal actually implements may be useful to reproduce behavior
observed on a smaller screen, or if the terminal malfunctions when using
its whole screen.
If lines is different from what it was previously, then the entire screen is cleared and redisplayed using the new size.
This function returns nil
.
This function declares that the terminal can display columns
columns. The details are as in set-screen-height
.

When a line of text extends beyond the right edge of a window, the line can either be truncated or continued on the next line. When a line is truncated, this is shown with a ‘$’ in the rightmost column of the window. When a line is continued or “wrapped” onto the next line, this is shown with a ‘\’ on the rightmost column of the window. The additional screen lines used to display a long text line are called continuation lines. (Note that wrapped lines are not filled; filling has nothing to do with continuation and truncation. @xref{Filling}.)
This buffer-local variable controls how Emacs displays lines that
extend beyond the right edge of the window. If it is non-nil
,
then Emacs does not display continuation lines; rather each line of
text occupies exactly one screen line, and a dollar sign appears at the
edge of any line that extends to or beyond the edge of the window. The
default is nil
.
If the variable truncate-partial-width-windows
is
non-nil
, then truncation is used for windows that are not the
full width of the screen, regardless of the value of
truncate-lines
.
This variable is the default value for truncate-lines
in buffers
that do not have local values for it.
This variable determines how lines that are too wide to fit on the
screen are displayed in side-by-side windows (@pxref{Splitting
Windows}). If it is non-nil
, then wide lines are truncated (with
a ‘$’ at the end of the line); otherwise they wrap to the next
screen line (with a ‘\’ at the end of the line).
You can override the images that indicate continuation or truncation with the display table; see Display Tables.

The echo area is used for displaying messages made with the
message
primitive, and for echoing keystrokes. It is not the
same as the minibuffer, despite the fact that the minibuffer appears
(when active) in the same place on the screen as the echo area. The
GNU Emacs Manual specifies the rules for resolving conflicts
between the echo area and the minibuffer for use of that screen space
(see The Minibuffer in The GNU Emacs Manual).
Error messages appear in the echo area; see @ref{Errors}.
You can write output in the echo area by using the Lisp printing
functions with t
as the stream (@pxref{Output Functions}), or as
follows:
This function prints a one-line message in the echo area. The
argument string is similar to a C language printf
control
string. See format
in @ref{String Conversion}, for the details
on the conversion specifications. message
returns the
constructed string.
If string is nil
, message
clears the echo area. If
the minibuffer is active, this brings the minibuffer contents back onto
the screen immediately.
(message "Minibuffer depth is %d." (minibuffer-depth)) ⇒ "Minibuffer depth is 0."
---------- Echo Area ---------- Minibuffer depth is 0. ---------- Echo Area ----------
This variable controls where the cursor appears when a message is
displayed in the echo area. If it is non-nil
, then the cursor
appears at the end of the message. Otherwise, the cursor appears at
point—not in the echo area at all.
The value is normally nil
; Lisp programs bind it to t
for brief periods of time.

Selective display is a class of minor modes in which specially marked lines do not appear on the screen, or in which highly indented lines do not appear.
The first variant, explicit selective display, is designed for use in a Lisp program. The program controls which lines are hidden by altering the text. Outline mode uses this variant. In the second variant, the choice of lines to hide is made automatically based on indentation. This variant is designed as a user-level feature.
The way you control explicit selective display is by replacing a newline (control-j) with a control-m. The text which was formerly a line following that newline is now invisible. Strictly speaking, it is temporarily no longer a line at all, since only newlines can separate lines; it is now part of the previous line.
Selective display does not directly affect editing commands. For
example, C-f (forward-char
) moves point unhesitatingly into
invisible space. However, the replacement of newline characters with
carriage return characters affects some editing commands. For example,
next-line
skips invisible lines, since it searches only for
newlines. Modes that use selective display can also define commands
that take account of the newlines, or which make parts of the text
visible or invisible.
When you write a selectively displayed buffer into a file, all the control-m’s are replaced by their original newlines. This means that when you next read in the file, it looks OK, with nothing invisible. The selective display effect is seen only within Emacs.
This buffer-local variable enables selective display. This means that lines, or portions of lines, may be made invisible.
selective-display
is t
, then any portion
of a line that follows a control-m is not displayed.
selective-display
is a positive integer, then
lines that start with more than selective-display
columns of
indentation are not displayed.
When some portion of a buffer is invisible, the vertical movement
commands operate as if that portion did not exist, allowing a single
next-line
command to skip any number of invisible lines.
However, character movement commands (such as forward-char
) do
not skip the invisible portion, and it is possible (if tricky) to insert
or delete text in an invisible portion.
In the examples below, what is shown is the display of the buffer
foo
, which changes with the value of selective-display
. The
contents of the buffer do not change.
(setq selective-display nil) ⇒ nil ---------- Buffer: foo ---------- 1 on this column 2on this column 3n this column 3n this column 2on this column 1 on this column ---------- Buffer: foo ----------
(setq selective-display 2) ⇒ 2 ---------- Buffer: foo ---------- 1 on this column 2on this column 2on this column 1 on this column ---------- Buffer: foo ----------
If this buffer-local variable is non-nil
, then Emacs displays
‘…’ at the end of a line that is followed by invisible text.
This example is a continuation of the previous one.
(setq selective-display-ellipses t) ⇒ t ---------- Buffer: foo ---------- 1 on this column 2on this column ... 2on this column 1 on this column ---------- Buffer: foo ----------
You can use a display table to substitute other text for the ellipsis (‘…’). See section Display Tables.

The overlay arrow is useful for directing the user’s attention to a particular line in a buffer. For example, in the modes used for interface to debuggers, the overlay arrow indicates the line of code about to be executed.
This variable holds the string to display as an arrow, or nil
if
the arrow feature is not in use.
This variable holds a marker which indicates where to display the arrow. It should point at the beginning of a line. The arrow text is displayed at the beginning of that line, overlaying any text that would otherwise appear. Since the arrow is usually short, and the line usually begins with indentation, normally nothing significant is overwritten.
The overlay string is displayed only in the buffer which this marker points into. Thus, only one buffer can have an overlay arrow at any given time.

Temporary displays are used by commands to put output into a buffer and then present it to the user for perusal rather than for editing. Many of the help commands use this feature.
This function executes forms while arranging to insert any output they print into the buffer named buffer-name. The buffer is then shown in some window for viewing, displayed but not selected.
The string buffer-name specifies the temporary buffer, which
need not already exist. The argument must be a string, not a buffer.
The buffer is erased initially (with no questions asked), and it is
marked as unmodified after with-output-to-temp-buffer
exits.
with-output-to-temp-buffer
binds standard-output
to the
temporary buffer, then it evaluates the forms in forms. Output
using the Lisp output functions within forms goes by default to
that buffer (but screen display and messages in the echo area, although
output in the general sense of the word, are not affected).
@xref{Output Functions}.
The value of the last form in forms is returned.
---------- Buffer: foo ---------- This is the contents of foo. ---------- Buffer: foo ----------
(with-output-to-temp-buffer "foo" (print 20) (print standard-output)) ⇒ #<buffer foo> ---------- Buffer: foo ---------- 20 #<buffer foo> ---------- Buffer: foo ----------
The value of this variable, if non-nil
, is called as a function
to display a help buffer. This variable is used by
with-output-to-temp-buffer
.
In Emacs versions 18 and earlier, this variable was called
temp-buffer-show-hook
.
This function momentarily displays string in the current buffer at position (which is a character offset from the beginning of the buffer). The display remains until the next character is typed.
If the next character the user types is char, Emacs ignores it. Otherwise, that character remains buffered for subsequent use as input. Thus, typing char will simply remove the string from the display, while typing (say) C-f will remove the string from the display and later (presumably) move point forward. The argument char is a space by default.
The return value of momentary-string-display
is not meaningful.
If message is non-nil
, it is displayed in the echo area
while string is displayed in the buffer. If it is nil
,
then instructions to type char are displayed there, e.g.,
‘Type RET to continue editing’.
In this example, point is initially located at the beginning of the second line:
---------- Buffer: foo ---------- This is the contents of foo. ∗Second line. ---------- Buffer: foo ----------
(momentary-string-display "**** Important Message! ****" (point) ?\r "Type RET when done reading") ⇒ t
---------- Buffer: foo ---------- This is the contents of foo. **** Important Message! ****Second line. ---------- Buffer: foo ---------- ---------- Echo Area ---------- Type RET when done reading ---------- Echo Area ----------
This function works by actually changing the text in the buffer. As a result, if you later undo in this buffer, you will see the message come and go.

You can use overlays to alter the appearance of a buffer’s text on the screen. An overlay is an object which belongs to a particular buffer, and has a specified beginning and end. It also has properties which you can examine and set; these affect the display of the text within the overlay.
1.8.1 Overlay Properties | How to read and set properties. What properties do to the screen display. | |
1.8.2 Managing Overlays | Creating, moving, finding overlays. |
[ << ] | [ < ] | [ Up ] | [ > ] | [ >> ] | [Top] | [Contents] | [Index] | [ ? ] |
Overlay properties are like text properties in some respects, but the differences are more important than the similarities. Text properties are considered a part of the text; overlays are specifically considered not to be part of the text. Thus, copying text between various buffers and strings preserves text properties, but does not try to preserve overlays. Changing a buffer’s text properties marks the buffer as modified, while moving an overlay or changing its properties does not.
face
This property controls the font and color of text. See section Faces, for more information. This feature is temporary; in the future, we may replace it with other ways of specifying how to display text.
mouse-face
This property is used instead of face
when the mouse is within
the range of the overlay. This feature is not yet implemented, and may
be temporary. It is documented here because we are likely to implement it
this way at least for a while.
priority
This property’s value (which should be a nonnegative number) determines
the priority of the overlay. The priority matters when two or more
overlays cover the same character and both specify a face for display;
the one whose priority
value is larger takes priority over the
other, and its face attributes override the face attributes of the lower
priority overlay.
Currently, all overlays take priority over text properties. Please avoid using negative priority values, as we have not yet decided just what they should mean.
window
If the window
property is non-nil
, then the overlay
applies only on that window.
before-string
This property’s value is a string to add to the display at the beginning of the overlay. The string does not appear in the buffer in any sense—only on the screen. This is not yet implemented, but will be.
after-string
This property’s value is a string to add to the display at the end of the overlay. The string does not appear in the buffer in any sense—only on the screen. This is not yet implemented, but will be.
These are the functions for reading and writing the properties of an overlay.
This function returns the value of property prop recorded in
overlay. If overlay does not record any value for that
property, then the value is nil
.
This function set the value of property prop recorded in overlay to value. It returns value.
[ << ] | [ < ] | [ Up ] | [ > ] | [ >> ] | [Top] | [Contents] | [Index] | [ ? ] |
This function creates and returns an overlay which belongs to buffer and ranges from start to end. Both start and end must specify buffer positions; they may be integers or markers. If buffer is omitted, the overlay is created in the current buffer.
The return value is the overlay itself.
This function returns the position at which overlay starts.
This function returns the position at which overlay ends.
This function returns the buffer that overlay belongs to.
This function deletes overlay. The overlay continues to exist as a Lisp object, but ceases to be part of the buffer it belonged to, and ceases to have any effect on display.
This function moves overlay to buffer, and places its bounds at start and end. Both arguments start and end must specify buffer positions; they may be integers or markers. If buffer is omitted, the overlay stays in the same buffer.
The return value is overlay.
This is the only valid way to change the endpoints of an overlay. Do not try modifying the markers in the overlay by hand, as that fails to update other vital data structures and can cause some overlays to be “lost”.
This function returns a list of all the overlays that contain position pos in the current buffer. The list is in no particular order. An overlay contains position pos if it begins at or before pos, and ends after pos.
This function returns the buffer position of the next beginning or end of an overlay, after pos.

A face is a named collection of graphical attributes: font, foreground color, background color and optional underlining. Faces control the display of text on the screen.
Each face has its own face id number which distinguishes faces at low levels within Emacs. However, for most purposes, you can refer to faces in Lisp programs by their names.
Each face name is meaningful for all frames, and by default it has the same meaning in all frames. But you can arrange to give a particular face name a special meaning in one frame if you wish.
The face named default
is used for ordinary text. The face named
modeline
is used for displaying the mode line and menu bars. The
face named region
is used for highlighting the region (in
Transient Mark mode only).
1.9.1 Merging Faces for Display | How Emacs decides which face to use for a character. | |
1.9.2 Functions for Working with Faces | How to define and examine faces. |
[ << ] | [ < ] | [ Up ] | [ > ] | [ >> ] | [Top] | [Contents] | [Index] | [ ? ] |
Here are all the ways to specify which face to use for display of text:
face
property; if so,
it’s displayed with that face. If the character has a mouse-face
property, that is used instead of the face
property when the mouse
is “near enough” to the character. @xref{Special Properties}.
face
and mouse-face
properties too; they apply to all the text covered by the overlay.
If these various sources together specify more than one face for a particular character, Emacs merges the attributes of the various faces specified. The attributes of the faces of special glyphs come first; then come attributes of faces from overlays, followed by those from text properties, and last the default face.
When multiple overlays cover one character, an overlay with higher priority overrides those with lower priority. See section Overlays.
If an attribute such as the font or a color is not specified in any of the above ways, the frame’s own font or color is used.
[ << ] | [ < ] | [ Up ] | [ > ] | [ >> ] | [Top] | [Contents] | [Index] | [ ? ] |
The attributes a face can specify include the font, the foreground
color, the background color, and underlining. The face can also leave
these unspecified by giving the value nil
for them.
Here are the primitives for creating and changing faces.
This function defines a new face named name, initially with all
attributes nil
. It does nothing if there is already a face named
name.
This function returns a list of all defined face names.
This function defines a new face named new which is a copy of the existing face named old. If there is already a face named new, then it alters the face to have the same attributes as old.
If the optional argument frame is given, this function applies only to that frame. Otherwise it applies to each frame individually.
You can modify the attributes of an existing face with the following functions. If you specify frame, they affect just that frame; otherwise, they affect all frames as well as the defaults that apply to new frames.
These functions set the foreground (respectively, background) color of face face to color. The argument color color should be a string, the name of a color.
This function sets the font of face face. The argument font should be a string.
This function sets the underline attribute of face face.
Swap the foreground and background colors of face face. If the face doesn’t specify both foreground and background, then its foreground and background are set to the default background and foreground.
These functions examine the attributes of a face. If you don’t specify frame, they refer to the default data for new frames.
These functions return the foreground (respectively, background) color of face face. The argument color color should be a string, the name of a color.
This function returns the name of the font of face face.
This function returns the underline attribute of face face.
This function returns the id number of face face.
This returns t
if the faces face1 and face2 have the
same attributes for display.
This returns t
if the face face displays differently from
the default face. A face is considered to be “the same” as the normal
face if each attribute is either the same as that of the default face or
nil
(meaning to inherit from the default).
This variable’s value specifies the face id to use to display characters in the region when it is active (in Transient Mark mode only). The face thus specified takes precedence over all faces that come from text properties and overlays, for characters in the region. @xref{The Mark}, for more information about Transient Mark mode.
Normally, the value is the id number of the face named region
.

This section describes the mechanism by which Emacs shows a matching open parenthesis when the user inserts a close parenthesis.
The value of this variable should be a function (of no arguments) to
be called whenever a char with close parenthesis syntax is inserted.
The value of blink-paren-function
may be nil
, in which
case nothing is done.
Please note: this variable was named
blink-paren-hook
in older Emacs versions, but since it is not called with the standard convention for hooks, it was renamed toblink-paren-function
in version 19.
If this variable is nil
, then blink-matching-open
does
nothing.
This variable specifies the maximum distance to scan for a matching parenthesis before giving up.
This function is the default value of blink-paren-function
. It
assumes that point follows a character with close parenthesis syntax and
moves the cursor momentarily to the matching opening character. If that
character is not already on the screen, then its context is shown by
displaying it in the echo area. To avoid long delays, this function
does not search farther than blink-matching-paren-distance
characters.
Here is an example of calling this function explicitly.
(defun interactive-blink-matching-open () "Indicate momentarily the start of sexp before point." (interactive)
(let ((blink-matching-paren-distance (buffer-size)) (blink-matching-paren t)) (blink-matching-open)))

This variable controls whether Emacs uses inverse video for all text
on the screen. Non-nil
means yes, nil
means no. The
default is nil
.
This variable controls the use of inverse video for mode lines. If it
is non-nil
, then mode lines are displayed in inverse video (under
X, this uses the face named modeline
, which you can set as you
wish). Otherwise, mode lines are displayed normally, just like text.
The default is t
.

The usual display conventions define how to display each character code. You can override these conventions by setting up a display table (see section Display Tables). Here are the usual display conventions:
tab-width
.
ctl-arrow
. If it is is
non-nil
, these codes map to sequences of two glyphs, where the
first glyph is the ASCII code for ‘^’. Otherwise, these codes map
just like the codes in the range 128 to 255.
The usual display conventions apply even when there is a display
table, for any character whose entry in the active display table is
nil
. Thus, when you set up a display table, you need only
specify the the characters for which you want unusual behavior.
These variables affect the way certain characters are displayed on the screen. Since they change the number of columns the characters occupy, they also affect the indentation functions.
This buffer-local variable controls how control characters are
displayed. If it is non-nil
, they are displayed as a caret
followed by the character: ‘^A’. If it is nil
, they are
displayed as a backslash followed by three octal digits: ‘\001’.
The value of this variable is the default value for ctl-arrow
in
buffers that do not override it. This is the same as executing the
following expression:
(default-value 'ctl-arrow)
@xref{Default Value}.
The value of this variable is the spacing between tab stops used for
displaying tab characters in Emacs buffers. The default is 8. Note
that this feature is completely independent from the user-settable tab
stops used by the command tab-to-tab-stop
. @xref{Indent Tabs}.

You can use the display table feature to control how all 256 possible character codes display on the screen. This is useful for displaying European languages that have letters not in the ASCII character set.
The display table maps each character code into a sequence of glyphs, each glyph being an image that takes up one character position on the screen. You can also define how to display each glyph on your terminal, using the glyph table.

A display table is actually an array of 261 elements.
This creates and returns a display table. The table initially has
nil
in all elements.
The first 256 elements correspond to character codes; the nth
element says how to display the character code n. The value
should be nil
or a vector of glyph values (see section Glyphs). If
an element is nil
, it says to display that character according to
the usual display conventions (see section Usual Display Conventions).
The remaining five elements of a display table serve special purposes,
and nil
means use the default stated below.
The glyph for the end of a truncated screen line (the default for this is ‘$’). See section Glyphs.
The glyph for the end of a continued line (the default is ‘\’).
The glyph for indicating a character displayed as an octal character code (the default is ‘\’).
The glyph for indicating a control character (the default is ‘^’).
A vector of glyphs for indicating the presence of invisible lines (the default is ‘...’). See section Selective Display.
For example, here is how to construct a display table that mimics the
effect of setting ctl-arrow
to a non-nil
value:
(setq disptab (make-display-table)) (let ((i 0)) (while (< i 32) (or (= i ?\t) (= i ?\n) (aset disptab i (vector ?^ (+ i 64)))) (setq i (1+ i))) (aset disptab 127 (vector ?^ ??)))

Each window can specify a display table, and so can each buffer. When a buffer b is displayed in window w, display uses the display table for window w if it has one; otherwise, the display table for buffer b if it has one; otherwise, the standard display table if any. The display table chosen is called the active display table.
This function returns window’s display table, or nil
if window does not have an assigned display table.
This function sets the display table of window to table.
The argument table should be either a display table or
nil
.
This variable is automatically local in all buffers; its value in a
particular buffer is the display table for that buffer, or nil
if
the buffer does not have any assigned display table.
This variable’s value is the default display table, used when neither
the current buffer nor the window displaying it has an assigned display
table. This variable is nil
by default.
If neither the selected window nor the current buffer has a display
table, and if the variable standard-display-table
is nil
,
then Emacs uses the usual display conventions. See section Usual Display Conventions.

A glyph is a generalization of a character; it stands for an image that takes up a single character position on the screen. Glyphs are represented in Lisp as integers, just as characters are.
The meaning of each integer, as a glyph, is defined by the glyph
table, which is the value of the variable glyph-table
.
The value of this variable is the current glyph table. It should be a
vector; the gth element defines glyph code g. If the value
is nil
instead of a vector, then all glyphs are simple (see
below).
Here are the possible types of elements in the glyph table:
Define this glyph code as an alias for code integer. This is used with X Windows to specify a face code.
Send the characters in string to the terminal to output this glyph. This alternative is available on character terminals, but not under X.
nil
This glyph is simple. On an ordinary terminal, the glyph code mod 256 is the character to output. With X, the glyph code mod 256 is character to output, and the glyph code divided by 256 specifies the face id number to use while outputting it. See section Faces.
If a glyph code is greater than or equal to the length of the glyph table, that code is automatically simple.

If you have a terminal that can handle the entire ISO Latin 1 character set, you can arrange to use that character set as follows:
(require 'disp-table) ;; Set char codes 160--255 to display as themselves. ;; (Codes 128--159 are the additional control characters.) (standard-display-8bit 160 255)
If you are editing buffers written in the ISO Latin 1 character set and your terminal doesn’t handle anything but ASCII, you can load the file ‘iso-ascii’ to set up a display table which makes the other ISO characters display as sequences of ASCII characters. For example, the character “o with umlaut” displays as ‘{"o}’.
Some European countries have terminals that don’t support ISO Latin 1 but do support the special characters for that country’s language. You can define a display table to work one language using such terminals. For an example, see ‘lisp/iso-swed.el’, which handles certain Swedish terminals.
You can load the appropriate display table for your terminal automatically by writing a terminal-specific Lisp file for the terminal type.

You can make Emacs ring a bell (or blink the screen) to attract the user’s attention. Be conservative about how often you do this; frequent bells can become irritating. Also be careful not to use beeping alone when signaling an error is appropriate. (@xref{Errors}.)
This function beeps, or flashes the screen (see visible-bell
below).
It also terminates any keyboard macro currently executing unless
dont-terminate is non-nil
.
This is a synonym for ding
.
This variable determines whether Emacs should flash the screen to
represent a bell. Non-nil
means yes, nil
means no. This
is effective only if the Termcap entry for the terminal in use has the
visible bell flag (‘vb’) set.

Emacs works with several window systems, most notably the X Window Syste,. Note that both Emacs and X use the term “window”, but use it differently. An Emacs frame is a single window as far as X is concerned; the individual Emacs windows are not known to X at all.
This variable tells Lisp programs what window system Emacs is running
under. Its value should be a symbol such as x
(if Emacs is
running under X) or nil
(if Emacs is running on an ordinary
terminal).
This variable distinguishes between different versions of the X Window
System. Its value is 10 or 11 when using X; nil
otherwise.
This variable is a normal hook which Emacs runs after loading your
‘.emacs’ file and the default initialization file (if any), after
loading terminal-specific Lisp code, and after running the hook
term-setup-hook
.
This hook is used for internal purposes: setting up communication with the window system, and creating the initial window. Users should not interfere with it.
