NAME
terminfo - terminal capability database
SYNOPSIS
/usr/share/misc/terminfo/*/*
DESCRIPTION
Terminfo is a data base describing terminals, used by screen-oriented
programs such as nvi(1), rogue(1) and libraries such as curses(3).
Terminfo describes terminals by giving a set of capabilities which they
have, by specifying how to perform screen operations, and by specifying
padding requirements and initialization sequences. This describes
ncurses version 5.7.
Entries in terminfo consist of a sequence of `,' separated fields
(embedded commas may be escaped with a backslash or notated as \054).
White space after the `,' separator is ignored. The first entry for
each terminal gives the names which are known for the terminal,
separated by `|' characters. The first name given is the most common
abbreviation for the terminal, the last name given should be a long
name fully identifying the terminal, and all others are understood as
synonyms for the terminal name. All names but the last should be in
lower case and contain no blanks; the last name may well contain upper
case and blanks for readability.
Lines beginning with a `#' in the first column are treated as comments.
While comment lines are legal at any point, the output of captoinfo and
infotocap (aliases for tic) will move comments so they occur only
between entries.
Newlines and leading tabs may be used for formatting entries for
readability. These are removed from parsed entries. The infocmp -f
option relies on this to format if-then-else expressions: the result
can be read by @tic.
Terminal names (except for the last, verbose entry) should be chosen
using the following conventions. The particular piece of hardware
making up the terminal should have a root name, thus ``hp2621''. This
name should not contain hyphens. Modes that the hardware can be in, or
user preferences, should be indicated by appending a hyphen and a mode
suffix. Thus, a vt100 in 132 column mode would be vt100-w. The
following suffixes should be used where possible:
Suffix Meaning Example
-nn Number of lines on the screen aaa-60
-np Number of pages of memory c100-4p
-am With automargins (usually the default) vt100-am
-m Mono mode; suppress color ansi-m
-mc Magic cookie; spaces when highlighting wy30-mc
-na No arrow keys (leave them in local) c100-na
-nam Without automatic margins vt100-nam
-nl No status line att4415-nl
-ns No status line hp2626-ns
-rv Reverse video c100-rv
-s Enable status line vt100-s
-vb Use visible bell instead of beep wy370-vb
-w Wide mode (> 80 columns, usually 132) vt100-w
For more on terminal naming conventions, see the term(7) manual page.
Capabilities
The following is a complete table of the capabilities included in a
terminfo description block and available to terminfo-using code. In
each line of the table,
The variable is the name by which the programmer (at the terminfo
level) accesses the capability.
The capname is the short name used in the text of the database, and is
used by a person updating the database. Whenever possible, capnames
are chosen to be the same as or similar to the ANSI X3.64-1979 standard
(now superseded by ECMA-48, which uses identical or very similar
names). Semantics are also intended to match those of the
specification.
The termcap code is the old termcap capability name (some capabilities
are new, and have names which termcap did not originate).
Capability names have no hard length limit, but an informal limit of 5
characters has been adopted to keep them short and to allow the tabs in
the source file Caps to line up nicely.
Finally, the description field attempts to convey the semantics of the
capability. You may find some codes in the description field:
(P) indicates that padding may be specified
#[1-9] in the description field indicates that the string is passed
through tparm with parms as given (#i).
(P*) indicates that padding may vary in proportion to the number of
lines affected
(#diu) indicates the iuthd parameter.
These are the boolean capabilities:

The XSI Curses standard added these. They are some post-4.1 versions
of System V curses, e.g., Solaris 2.5 and IRIX 6.x. The ncurses
termcap names for them are invented; according to the XSI Curses
standard, they have no termcap names. If your compiled terminfo
entries use these, they may not be binary-compatible with System V
terminfo entries after SVr4.1; beware!

Entries may continue onto multiple lines by placing white space at the
beginning of each line except the first. Comments may be included on
lines beginning with ``#''. Capabilities in terminfo are of three
types: Boolean capabilities which indicate that the terminal has some
particular feature, numeric capabilities giving the size of the
terminal or the size of particular delays, and string capabilities,
which give a sequence which can be used to perform particular terminal
operations.
Types of Capabilities
All capabilities have names. For instance, the fact that ANSI-standard
terminals have automatic margins (i.e., an automatic return and
line-feed when the end of a line is reached) is indicated by the
capability am. Hence the description of ansi includes am. Numeric
capabilities are followed by the character `#' and then a positive
value. Thus cols, which indicates the number of columns the terminal
has, gives the value `80' for ansi. Values for numeric capabilities
may be specified in decimal, octal or hexadecimal, using the C
programming language conventions (e.g., 255, 0377 and 0xff or 0xFF).
Finally, string valued capabilities, such as el (clear to end of line
sequence) are given by the two-character code, an `=', and then a
string ending at the next following `,'.
A number of escape sequences are provided in the string valued
capabilities for easy encoding of characters there. Both \E and \e map
to an ESCAPE character, ^x maps to a control-x for any appropriate x,
and the sequences \n \l \r \t \b \f \s give a newline, line-feed,
return, tab, backspace, form-feed, and space. Other escapes include \^
for ^, \\ for \, \, for comma, \: for :, and \0 for null. (\0 will
produce \200, which does not terminate a string but behaves as a null
character on most terminals, providing CS7 is specified. See stty(1).)
Finally, characters may be given as three octal digits after a \.
A delay in milliseconds may appear anywhere in a string capability,
enclosed in $<..> brackets, as in el=\EK$<5>, and padding characters
are supplied by tputs to provide this delay. The delay must be a
number with at most one decimal place of precision; it may be followed
by suffixes `*' or '/' or both. A `*' indicates that the padding
required is proportional to the number of lines affected by the
operation, and the amount given is the per-affected-unit padding
required. (In the case of insert character, the factor is still the
number of lines affected.) Normally, padding is advisory if the device
has the xon capability; it is used for cost computation but does not
trigger delays. A `/' suffix indicates that the padding is mandatory
and forces a delay of the given number of milliseconds even on devices
for which xon is present to indicate flow control.
Sometimes individual capabilities must be commented out. To do this,
put a period before the capability name. For example, see the second
ind in the example above.
Fetching Compiled Descriptions
If the environment variable TERMINFO is set, it is interpreted as the
pathname of a directory containing the compiled description you are
working on. Only that directory is searched.
If TERMINFO is not set, the ncurses version of the terminfo reader code
will instead look in the directory $HOME/.terminfo for a compiled
description. If it fails to find one there, and the environment
variable TERMINFO_DIRS is set, it will interpret the contents of that
variable as a list of colon- separated directories to be searched (an
empty entry is interpreted as a command to search
/usr/share/misc/terminfo). If no description is found in any of the
TERMINFO_DIRS directories, the fetch fails.
If neither TERMINFO nor TERMINFO_DIRS is set, the last place tried will
be the system terminfo directory, /usr/share/misc/terminfo.
(Neither the $HOME/.terminfo lookups nor TERMINFO_DIRS extensions are
supported under stock System V terminfo/curses.)
Preparing Descriptions
We now outline how to prepare descriptions of terminals. The most
effective way to prepare a terminal description is by imitating the
description of a similar terminal in terminfo and to build up a
description gradually, using partial descriptions with vi or some other
screen-oriented program to check that they are correct. Be aware that
a very unusual terminal may expose deficiencies in the ability of the
terminfo file to describe it or bugs in the screen-handling code of the
test program.
To get the padding for insert line right (if the terminal manufacturer
did not document it) a severe test is to edit a large file at 9600
baud, delete 16 or so lines from the middle of the screen, then hit the
`u' key several times quickly. If the terminal messes up, more padding
is usually needed. A similar test can be used for insert character.
Basic Capabilities
The number of columns on each line for the terminal is given by the
cols numeric capability. If the terminal is a CRT, then the number of
lines on the screen is given by the lines capability. If the terminal
wraps around to the beginning of the next line when it reaches the
right margin, then it should have the am capability. If the terminal
can clear its screen, leaving the cursor in the home position, then
this is given by the clear string capability. If the terminal
overstrikes (rather than clearing a position when a character is struck
over) then it should have the os capability. If the terminal is a
printing terminal, with no soft copy unit, give it both hc and os. (os
applies to storage scope terminals, such as TEKTRONIX 4010 series, as
well as hard copy and APL terminals.) If there is a code to move the
cursor to the left edge of the current row, give this as cr. (Normally
this will be carriage return, control M.) If there is a code to
produce an audible signal (bell, beep, etc) give this as bel.
If there is a code to move the cursor one position to the left (such as
backspace) that capability should be given as cub1. Similarly, codes to
move to the right, up, and down should be given as cuf1, cuu1, and
cud1. These local cursor motions should not alter the text they pass
over, for example, you would not normally use `cuf1= ' because the
space would erase the character moved over.
A very important point here is that the local cursor motions encoded in
terminfo are undefined at the left and top edges of a CRT terminal.
Programs should never attempt to backspace around the left edge, unless
bw is given, and never attempt to go up locally off the top. In order
to scroll text up, a program will go to the bottom left corner of the
screen and send the ind (index) string.
To scroll text down, a program goes to the top left corner of the
screen and sends the ri (reverse index) string. The strings ind and ri
are undefined when not on their respective corners of the screen.
Parameterized versions of the scrolling sequences are indn and rin
which have the same semantics as ind and ri except that they take one
parameter, and scroll that many lines. They are also undefined except
at the appropriate edge of the screen.
The am capability tells whether the cursor sticks at the right edge of
the screen when text is output, but this does not necessarily apply to
a cuf1 from the last column. The only local motion which is defined
from the left edge is if bw is given, then a cub1 from the left edge
will move to the right edge of the previous row. If bw is not given,
the effect is undefined. This is useful for drawing a box around the
edge of the screen, for example. If the terminal has switch selectable
automatic margins, the terminfo file usually assumes that this is on;
i.e., am. If the terminal has a command which moves to the first
column of the next line, that command can be given as nel (newline).
It does not matter if the command clears the remainder of the current
line, so if the terminal has no cr and lf it may still be possible to
craft a working nel out of one or both of them.
These capabilities suffice to describe hard-copy and ``glass-tty''
terminals. Thus the model 33 teletype is described as
33|tty33|tty|model 33 teletype,
bel=^G, cols#72, cr=^M, cud1=^J, hc, ind=^J, os,
while the Lear Siegler ADM-3 is described as
adm3|3|lsi adm3,
am, bel=^G, clear=^Z, cols#80, cr=^M, cub1=^H, cud1=^J,
ind=^J, lines#24,
Parameterized Strings
Cursor addressing and other strings requiring parameters in the
terminal are described by a parameterized string capability, with
printf(3) like escapes %x in it. For example, to address the cursor,
the cup capability is given, using two parameters: the row and column
to address to. (Rows and columns are numbered from zero and refer to
the physical screen visible to the user, not to any unseen memory.) If
the terminal has memory relative cursor addressing, that can be
indicated by mrcup.
The parameter mechanism uses a stack and special % codes to manipulate
it. Typically a sequence will push one of the parameters onto the
stack and then print it in some format. Print (e.g., "%d") is a
special case. Other operations, including "%t" pop their operand from
the stack. It is noted that more complex operations are often
necessary, e.g., in the sgr string.
The % encodings have the following meanings:
%% outputs `%'
%[[:]flags][width[.precision]][doxXs]
as in printf, flags are [-+#] and space. Use a `:' to allow the
next character to be a `-' flag, avoiding interpreting "%-" as an
operator.
%c print pop() like %c in printf
%s print pop() like %s in printf
%p[1-9]
push i'th parameter
%P[a-z]
set dynamic variable [a-z] to pop()
%g[a-z]
get dynamic variable [a-z] and push it
%P[A-Z]
set static variable [a-z] to pop()
%g[A-Z]
get static variable [a-z] and push it
The terms "static" and "dynamic" are misleading. Historically,
these are simply two different sets of variables, whose values are
not reset between calls to tparm. However, that fact is not
documented in other implementations. Relying on it will adversely
impact portability to other implementations.

%? expr %t thenpart %e elsepart %;
This forms an if-then-else. The %e elsepart is optional. Usually
the %? expr part pushes a value onto the stack, and %t pops it
from the stack, testing if it is nonzero (true). If it is zero
(false), control passes to the %e (else) part.
It is possible to form else-if's a la Algol 68:
%? cd1u %t bd1u %e cd2u %t bd2u %e cd3u %t bd3u %e cd4u %t bd4u %e
%;
where cdiu are conditions, bdiu are bodies.
Use the -f option of tic or infocmp to see the structure of
if-the-else's. Some strings, e.g., sgr can be very complicated
when written on one line. The -f option splits the string into
lines with the parts indented.
Binary operations are in postfix form with the operands in the usual
order. That is, to get x-5 one would use "%gx%{5}%-". %P and %g
variables are persistent across escape-string evaluations.
Consider the HP2645, which, to get to row 3 and column 12, needs to be
sent \E&a12c03Y padded for 6 milliseconds. Note that the order of the
rows and columns is inverted here, and that the row and column are
printed as two digits. Thus its cup capability is
``cup=6\E&%p2%2dc%p1%2dY''.
The Microterm ACT-IV needs the current row and column sent preceded by
a ^T, with the row and column simply encoded in binary,
``cup=^T%p1%c%p2%c''. Terminals which use ``%c'' need to be able to
backspace the cursor (cub1), and to move the cursor up one line on the
screen (cuu1). This is necessary because it is not always safe to
transmit \n ^D and \r, as the system may change or discard them. (The
library routines dealing with terminfo set tty modes so that tabs are
never expanded, so \t is safe to send. This turns out to be essential
for the Ann Arbor 4080.)
A final example is the LSI ADM-3a, which uses row and column offset by
a blank character, thus ``cup=\E=%p1%' '%+%c%p2%' '%+%c''. After
sending `\E=', this pushes the first parameter, pushes the ASCII value
for a space (32), adds them (pushing the sum on the stack in place of
the two previous values) and outputs that value as a character. Then
the same is done for the second parameter. More complex arithmetic is
possible using the stack.
Cursor Motions
If the terminal has a fast way to home the cursor (to very upper left
corner of screen) then this can be given as home; similarly a fast way
of getting to the lower left-hand corner can be given as ll; this may
involve going up with cuu1 from the home position, but a program should
never do this itself (unless ll does) because it can make no assumption
about the effect of moving up from the home position. Note that the
home position is the same as addressing to (0,0): to the top left
corner of the screen, not of memory. (Thus, the \EH sequence on HP
terminals cannot be used for home.)
If the terminal has row or column absolute cursor addressing, these can
be given as single parameter capabilities hpa (horizontal position
absolute) and vpa (vertical position absolute). Sometimes these are
shorter than the more general two parameter sequence (as with the
hp2645) and can be used in preference to cup. If there are
parameterized local motions (e.g., move n spaces to the right) these
can be given as cud, cub, cuf, and cuu with a single parameter
indicating how many spaces to move. These are primarily useful if the
terminal does not have cup, such as the TEKTRONIX 4025.
If the terminal needs to be in a special mode when running a program
that uses these capabilities, the codes to enter and exit this mode can
be given as smcup and rmcup. This arises, for example, from terminals
like the Concept with more than one page of memory. If the terminal
has only memory relative cursor addressing and not screen relative
cursor addressing, a one screen-sized window must be fixed into the
terminal for cursor addressing to work properly. This is also used for
the TEKTRONIX 4025, where smcup sets the command character to be the
one used by terminfo. If the smcup sequence will not restore the
screen after an rmcup sequence is output (to the state prior to
outputting rmcup), specify nrrmc.
Area Clears
If the terminal can clear from the current position to the end of the
line, leaving the cursor where it is, this should be given as el. If
the terminal can clear from the beginning of the line to the current
position inclusive, leaving the cursor where it is, this should be
given as el1. If the terminal can clear from the current position to
the end of the display, then this should be given as ed. Ed is only
defined from the first column of a line. (Thus, it can be simulated by
a request to delete a large number of lines, if a true ed is not
available.)
Insert/delete line and vertical motions
If the terminal can open a new blank line before the line where the
cursor is, this should be given as il1; this is done only from the
first position of a line. The cursor must then appear on the newly
blank line. If the terminal can delete the line which the cursor is
on, then this should be given as dl1; this is done only from the first
position on the line to be deleted. Versions of il1 and dl1 which take
a single parameter and insert or delete that many lines can be given as
il and dl.
If the terminal has a settable scrolling region (like the vt100) the
command to set this can be described with the csr capability, which
takes two parameters: the top and bottom lines of the scrolling region.
The cursor position is, alas, undefined after using this command.
It is possible to get the effect of insert or delete line using csr on
a properly chosen region; the sc and rc (save and restore cursor)
commands may be useful for ensuring that your synthesized insert/delete
string does not move the cursor. (Note that the ncurses(3) library
does this synthesis automatically, so you need not compose
insert/delete strings for an entry with csr).
Yet another way to construct insert and delete might be to use a
combination of index with the memory-lock feature found on some
terminals (like the HP-700/90 series, which however also has
insert/delete).
Inserting lines at the top or bottom of the screen can also be done
using ri or ind on many terminals without a true insert/delete line,
and is often faster even on terminals with those features.
The boolean non_dest_scroll_region should be set if each scrolling
window is effectively a view port on a screen-sized canvas. To test
for this capability, create a scrolling region in the middle of the
screen, write something to the bottom line, move the cursor to the top
of the region, and do ri followed by dl1 or ind. If the data scrolled
off the bottom of the region by the ri re-appears, then scrolling is
non-destructive. System V and XSI Curses expect that ind, ri, indn,
and rin will simulate destructive scrolling; their documentation
cautions you not to define csr unless this is true. This curses
implementation is more liberal and will do explicit erases after
scrolling if ndstr is defined.
If the terminal has the ability to define a window as part of memory,
which all commands affect, it should be given as the parameterized
string wind. The four parameters are the starting and ending lines in
memory and the starting and ending columns in memory, in that order.
If the terminal can retain display memory above, then the da capability
should be given; if display memory can be retained below, then db
should be given. These indicate that deleting a line or scrolling may
bring non-blank lines up from below or that scrolling back with ri may
bring down non-blank lines.
Insert/Delete Character
There are two basic kinds of intelligent terminals with respect to
insert/delete character which can be described using terminfo. The most
common insert/delete character operations affect only the characters on
the current line and shift characters off the end of the line rigidly.
Other terminals, such as the Concept 100 and the Perkin Elmer Owl, make
a distinction between typed and untyped blanks on the screen, shifting
upon an insert or delete only to an untyped blank on the screen which
is either eliminated, or expanded to two untyped blanks. You can
determine the kind of terminal you have by clearing the screen and then
typing text separated by cursor motions. Type ``abc def'' using
local cursor motions (not spaces) between the ``abc'' and the ``def''.
Then position the cursor before the ``abc'' and put the terminal in
insert mode. If typing characters causes the rest of the line to shift
rigidly and characters to fall off the end, then your terminal does not
distinguish between blanks and untyped positions. If the ``abc''
shifts over to the ``def'' which then move together around the end of
the current line and onto the next as you insert, you have the second
type of terminal, and should give the capability in, which stands for
``insert null''. While these are two logically separate attributes
(one line versus multi-line insert mode, and special treatment of
untyped spaces) we have seen no terminals whose insert mode cannot be
described with the single attribute.
Terminfo can describe both terminals which have an insert mode, and
terminals which send a simple sequence to open a blank position on the
current line. Give as smir the sequence to get into insert mode. Give
as rmir the sequence to leave insert mode. Now give as ich1 any
sequence needed to be sent just before sending the character to be
inserted. Most terminals with a true insert mode will not give ich1;
terminals which send a sequence to open a screen position should give
it here.
If your terminal has both, insert mode is usually preferable to ich1.
Technically, you should not give both unless the terminal actually
requires both to be used in combination. Accordingly, some non-curses
applications get confused if both are present; the symptom is doubled
characters in an update using insert. This requirement is now rare;
most ich sequences do not require previous smir, and most smir insert
modes do not require ich1 before each character. Therefore, the new
curses actually assumes this is the case and uses either rmir/smir or
ich/ich1 as appropriate (but not both). If you have to write an entry
to be used under new curses for a terminal old enough to need both,
include the rmir/smir sequences in ich1.
If post insert padding is needed, give this as a number of milliseconds
in ip (a string option). Any other sequence which may need to be sent
after an insert of a single character may also be given in ip. If your
terminal needs both to be placed into an `insert mode' and a special
code to precede each inserted character, then both smir/rmir and ich1
can be given, and both will be used. The ich capability, with one
parameter, n, will repeat the effects of ich1 n times.
If padding is necessary between characters typed while not in insert
mode, give this as a number of milliseconds padding in rmp.
It is occasionally necessary to move around while in insert mode to
delete characters on the same line (e.g., if there is a tab after the
insertion position). If your terminal allows motion while in insert
mode you can give the capability mir to speed up inserting in this
case. Omitting mir will affect only speed. Some terminals (notably
Datamedia's) must not have mir because of the way their insert mode
works.
Finally, you can specify dch1 to delete a single character, dch with
one parameter, n, to delete n characters, and delete mode by giving
smdc and rmdc to enter and exit delete mode (any mode the terminal
needs to be placed in for dch1 to work).
A command to erase n characters (equivalent to outputting n blanks
without moving the cursor) can be given as ech with one parameter.
Highlighting, Underlining, and Visible Bells
If your terminal has one or more kinds of display attributes, these can
be represented in a number of different ways. You should choose one
display form as standout mode, representing a good, high contrast,
easy-on-the-eyes, format for highlighting error messages and other
attention getters. (If you have a choice, reverse video plus
half-bright is good, or reverse video alone.) The sequences to enter
and exit standout mode are given as smso and rmso, respectively. If
the code to change into or out of standout mode leaves one or even two
blank spaces on the screen, as the TVI 912 and Teleray 1061 do, then
xmc should be given to tell how many spaces are left.
Codes to begin underlining and end underlining can be given as smul and
rmul respectively. If the terminal has a code to underline the current
character and move the cursor one space to the right, such as the
Microterm Mime, this can be given as uc.
Other capabilities to enter various highlighting modes include blink
(blinking) bold (bold or extra bright) dim (dim or half-bright) invis
(blanking or invisible text) prot (protected) rev (reverse video) sgr0
(turn off all attribute modes) smacs (enter alternate character set
mode) and rmacs (exit alternate character set mode). Turning on any of
these modes singly may or may not turn off other modes.
If there is a sequence to set arbitrary combinations of modes, this
should be given as sgr (set attributes), taking 9 parameters. Each
parameter is either 0 or nonzero, as the corresponding attribute is on
or off. The 9 parameters are, in order: standout, underline, reverse,
blink, dim, bold, blank, protect, alternate character set. Not all
modes need be supported by sgr, only those for which corresponding
separate attribute commands exist.
For example, the DEC vt220 supports most of the modes:
tparm parameter attribute escape sequence
none none \E[0m
p1 standout \E[0;1;7m
p2 underline \E[0;4m
p3 reverse \E[0;7m
p4 blink \E[0;5m
p5 dim not available
p6 bold \E[0;1m
p7 invis \E[0;8m
p8 protect not used
p9 altcharset ^O (off) ^N (on)
We begin each escape sequence by turning off any existing modes, since
there is no quick way to determine whether they are active. Standout
is set up to be the combination of reverse and bold. The vt220
terminal has a protect mode, though it is not commonly used in sgr
because it protects characters on the screen from the host's erasures.
The altcharset mode also is different in that it is either ^O or ^N,
depending on whether it is off or on. If all modes are turned on, the
resulting sequence is \E[0;1;4;5;7;8m^N.
Some sequences are common to different modes. For example, ;7 is
output when either p1 or p3 is true, that is, if either standout or
reverse modes are turned on.
Writing out the above sequences, along with their dependencies yields
sequence when to output terminfo translation
\E[0 always \E[0
;1 if p1 or p6 %?%p1%p6%|%t;1%;
;4 if p2 %?%p2%|%t;4%;
;5 if p4 %?%p4%|%t;5%;
;7 if p1 or p3 %?%p1%p3%|%t;7%;
;8 if p7 %?%p7%|%t;8%;
m always m
^N or ^O if p9 ^N, else ^O %?%p9%t^N%e^O%;
Putting this all together into the sgr sequence gives:
sgr=\E[0%?%p1%p6%|%t;1%;%?%p2%t;4%;%?%p1%p3%|%t;7%;
%?%p4%t;5%;%?%p7%t;8%;m%?%p9%t\016%e\017%;,
Remember that if you specify sgr, you must also specify sgr0. Also,
some implementations rely on sgr being given if sgr0 is, Not all
terminfo entries necessarily have an sgr string, however. Many
terminfo entries are derived from termcap entries which have no sgr
string. The only drawback to adding an sgr string is that termcap also
assumes that sgr0 does not exit alternate character set mode.
Terminals with the ``magic cookie'' glitch (xmc) deposit special
``cookies'' when they receive mode-setting sequences, which affect the
display algorithm rather than having extra bits for each character.
Some terminals, such as the HP 2621, automatically leave standout mode
when they move to a new line or the cursor is addressed. Programs
using standout mode should exit standout mode before moving the cursor
or sending a newline, unless the msgr capability, asserting that it is
safe to move in standout mode, is present.
If the terminal has a way of flashing the screen to indicate an error
quietly (a bell replacement) then this can be given as flash; it must
not move the cursor.
If the cursor needs to be made more visible than normal when it is not
on the bottom line (to make, for example, a non-blinking underline into
an easier to find block or blinking underline) give this sequence as
cvvis. If there is a way to make the cursor completely invisible, give
that as civis. The capability cnorm should be given which undoes the
effects of both of these modes.
If your terminal correctly generates underlined characters (with no
special codes needed) even though it does not overstrike, then you
should give the capability ul. If a character overstriking another
leaves both characters on the screen, specify the capability os. If
overstrikes are erasable with a blank, then this should be indicated by
giving eo.
Keypad and Function Keys
If the terminal has a keypad that transmits codes when the keys are
pressed, this information can be given. Note that it is not possible
to handle terminals where the keypad only works in local (this applies,
for example, to the unshifted HP 2621 keys). If the keypad can be set
to transmit or not transmit, give these codes as smkx and rmkx.
Otherwise the keypad is assumed to always transmit. The codes sent by
the left arrow, right arrow, up arrow, down arrow, and home keys can be
given as kcub1, kcuf1, kcuu1, kcud1, and khome respectively. If there
are function keys such as f0, f1, ..., f10, the codes they send can be
given as kf0, kf1, ..., kf10. If these keys have labels other than the
default f0 through f10, the labels can be given as lf0, lf1, ..., lf10.
The codes transmitted by certain other special keys can be given: kll
(home down), kbs (backspace), ktbc (clear all tabs), kctab (clear the
tab stop in this column), kclr (clear screen or erase key), kdch1
(delete character), kdl1 (delete line), krmir (exit insert mode), kel
(clear to end of line), ked (clear to end of screen), kich1 (insert
character or enter insert mode), kil1 (insert line), knp (next page),
kpp (previous page), kind (scroll forward/down), kri (scroll
backward/up), khts (set a tab stop in this column). In addition, if
the keypad has a 3 by 3 array of keys including the four arrow keys,
the other five keys can be given as ka1, ka3, kb2, kc1, and kc3. These
keys are useful when the effects of a 3 by 3 directional pad are
needed.
Strings to program function keys can be given as pfkey, pfloc, and pfx.
A string to program screen labels should be specified as pln. Each of
these strings takes two parameters: the function key number to program
(from 0 to 10) and the string to program it with. Function key numbers
out of this range may program undefined keys in a terminal dependent
manner. The difference between the capabilities is that pfkey causes
pressing the given key to be the same as the user typing the given
string; pfloc causes the string to be executed by the terminal in
local; and pfx causes the string to be transmitted to the computer.
The capabilities nlab, lw and lh define the number of programmable
screen labels and their width and height. If there are commands to
turn the labels on and off, give them in smln and rmln. smln is
normally output after one or more pln sequences to make sure that the
change becomes visible.
Tabs and Initialization
If the terminal has hardware tabs, the command to advance to the next
tab stop can be given as ht (usually control I). A ``back-tab''
command which moves leftward to the preceding tab stop can be given as
cbt. By convention, if the teletype modes indicate that tabs are being
expanded by the computer rather than being sent to the terminal,
programs should not use ht or cbt even if they are present, since the
user may not have the tab stops properly set. If the terminal has
hardware tabs which are initially set every n spaces when the terminal
is powered up, the numeric parameter it is given, showing the number of
spaces the tabs are set to. This is normally used by the tset command
to determine whether to set the mode for hardware tab expansion, and
whether to set the tab stops. If the terminal has tab stops that can
be saved in non-volatile memory, the terminfo description can assume
that they are properly set.
Other capabilities include is1, is2, and is3, initialization strings
for the terminal, iprog, the path name of a program to be run to
initialize the terminal, and if, the name of a file containing long
initialization strings. These strings are expected to set the terminal
into modes consistent with the rest of the terminfo description. They
are normally sent to the terminal, by the init option of the tput
program, each time the user logs in. They will be printed in the
following order:
run the program
iprog
output is1 is2
set the margins using
mgc, smgl and smgr
set tabs using
tbc and hts
print the file
if
and finally
output is3.
Most initialization is done with is2. Special terminal modes can be set
up without duplicating strings by putting the common sequences in is2
and special cases in is1 and is3.
A set of sequences that does a harder reset from a totally unknown
state can be given as rs1, rs2, rf and rs3, analogous to is1, is2, if
and is3 respectively. These strings are output by the reset program,
which is used when the terminal gets into a wedged state. Commands are
normally placed in rs1, rs2 rs3 and rf only if they produce annoying
effects on the screen and are not necessary when logging in. For
example, the command to set the vt100 into 80-column mode would
normally be part of is2, but it causes an annoying glitch of the screen
and is not normally needed since the terminal is usually already in 80
column mode.
The reset program writes strings including iprog, etc., in the same
order as the init program, using rs1, etc., instead of is1, etc. If
any of rs1, rs2, rs3, or rf reset capability strings are missing, the
reset program falls back upon the corresponding initialization
capability string.
If there are commands to set and clear tab stops, they can be given as
tbc (clear all tab stops) and hts (set a tab stop in the current column
of every row). If a more complex sequence is needed to set the tabs
than can be described by this, the sequence can be placed in is2 or if.
Delays and Padding
Many older and slower terminals do not support either XON/XOFF or DTR
handshaking, including hard copy terminals and some very archaic CRTs
(including, for example, DEC VT100s). These may require padding
characters after certain cursor motions and screen changes.
If the terminal uses xon/xoff handshaking for flow control (that is, it
automatically emits ^S back to the host when its input buffers are
close to full), set xon. This capability suppresses the emission of
padding. You can also set it for memory-mapped console devices
effectively that do not have a speed limit. Padding information should
still be included so that routines can make better decisions about
relative costs, but actual pad characters will not be transmitted.
If pb (padding baud rate) is given, padding is suppressed at baud rates
below the value of pb. If the entry has no padding baud rate, then
whether padding is emitted or not is completely controlled by xon.
If the terminal requires other than a null (zero) character as a pad,
then this can be given as pad. Only the first character of the pad
string is used.
Status Lines
Some terminals have an extra `status line' which is not normally used
by software (and thus not counted in the terminal's lines capability).
The simplest case is a status line which is cursor-addressable but not
part of the main scrolling region on the screen; the Heathkit H19 has a
status line of this kind, as would a 24-line VT100 with a 23-line
scrolling region set up on initialization. This situation is indicated
by the hs capability.
Some terminals with status lines need special sequences to access the
status line. These may be expressed as a string with single parameter
tsl which takes the cursor to a given zero-origin column on the status
line. The capability fsl must return to the main-screen cursor
positions before the last tsl. You may need to embed the string values
of sc (save cursor) and rc (restore cursor) in tsl and fsl to
accomplish this.
The status line is normally assumed to be the same width as the width
of the terminal. If this is untrue, you can specify it with the
numeric capability wsl.
A command to erase or blank the status line may be specified as dsl.
The boolean capability eslok specifies that escape sequences, tabs,
etc., work ordinarily in the status line.
The ncurses implementation does not yet use any of these capabilities.
They are documented here in case they ever become important.
Line Graphics
Many terminals have alternate character sets useful for forms-drawing.
Terminfo and curses build in support for the drawing characters
supported by the VT100, with some characters from the AT&T 4410v1
added. This alternate character set may be specified by the acsc
capability.
Glyph ACS Ascii VT100
Name Name Default Name
UK pound sign ACS_STERLING f }
arrow pointing down ACS_DARROW v .
arrow pointing left ACS_LARROW < ,
arrow pointing right ACS_RARROW > +
arrow pointing up ACS_UARROW ^ -

scan line 1 ACS_S1 ~ o

scan line 9 ACS_S9 _ s
solid square block ACS_BLOCK # 0

tee pointing right ACS_LTEE + t
tee pointing up ACS_BTEE + v
upper left corner ACS_ULCORNER + l
upper right corner ACS_URCORNER + k
vertical line ACS_VLINE | x
The best way to define a new device's graphics set is to add a column
to a copy of this table for your terminal, giving the character which
(when emitted between smacs/rmacs switches) will be rendered as the
corresponding graphic. Then read off the VT100/your terminal character
pairs right to left in sequence; these become the ACSC string.
Color Handling
Most color terminals are either `Tektronix-like' or `HP-like'.
Tektronix-like terminals have a predefined set of N colors (where N
usually 8), and can set character-cell foreground and background
characters independently, mixing them into N * N color-pairs. On
HP-like terminals, the use must set each color pair up separately
(foreground and background are not independently settable). Up to M
color-pairs may be set up from 2*M different colors. ANSI-compatible
terminals are Tektronix-like.
Some basic color capabilities are independent of the color method. The
numeric capabilities colors and pairs specify the maximum numbers of
colors and color-pairs that can be displayed simultaneously. The op
(original pair) string resets foreground and background colors to their
default values for the terminal. The oc string resets all colors or
color-pairs to their default values for the terminal. Some terminals
(including many PC terminal emulators) erase screen areas with the
current background color rather than the power-up default background;
these should have the boolean capability bce.
To change the current foreground or background color on a
Tektronix-type terminal, use setaf (set ANSI foreground) and setab (set
ANSI background) or setf (set foreground) and setb (set background).
These take one parameter, the color number. The SVr4 documentation
describes only setaf/setab; the XPG4 draft says that "If the terminal
supports ANSI escape sequences to set background and foreground, they
should be coded as setaf and setab, respectively. If the terminal
supports other escape sequences to set background and foreground, they
should be coded as setf and setb, respectively. The vidputs() function
and the refresh functions use setaf and setab if they are defined."
The setaf/setab and setf/setb capabilities take a single numeric
argument each. Argument values 0-7 of setaf/setab are portably defined
as follows (the middle column is the symbolic #define available in the
header for the curses or ncurses libraries). The terminal hardware is
free to map these as it likes, but the RGB values indicate normal
locations in color space.
Color #define Value RGB
black COLOR_BLACK 0 0, 0, 0
red COLOR_RED 1 max,0,0
green COLOR_GREEN 2 0,max,0
yellow COLOR_YELLOW 3 max,max,0
blue COLOR_BLUE 4 0,0,max
magenta COLOR_MAGENTA 5 max,0,max
cyan COLOR_CYAN 6 0,max,max
white COLOR_WHITE 7 max,max,max
The argument values of setf/setb historically correspond to a different
mapping, i.e.,
Color #define Value RGB
black COLOR_BLACK 0 0, 0, 0
blue COLOR_BLUE 1 0,0,max
green COLOR_GREEN 2 0,max,0
cyan COLOR_CYAN 3 0,max,max
red COLOR_RED 4 max,0,0
magenta COLOR_MAGENTA 5 max,0,max
yellow COLOR_YELLOW 6 max,max,0
white COLOR_WHITE 7 max,max,max
It is important to not confuse the two sets of color capabilities;
otherwise red/blue will be interchanged on the display.
On an HP-like terminal, use scp with a color-pair number parameter to
set which color pair is current.
On a Tektronix-like terminal, the capability ccc may be present to
indicate that colors can be modified. If so, the initc capability will
take a color number (0 to colors - 1)and three more parameters which
describe the color. These three parameters default to being
interpreted as RGB (Red, Green, Blue) values. If the boolean
capability hls is present, they are instead as HLS (Hue, Lightness,
Saturation) indices. The ranges are terminal-dependent.
On an HP-like terminal, initp may give a capability for changing a
color-pair value. It will take seven parameters; a color-pair number
(0 to max_pairs - 1), and two triples describing first background and
then foreground colors. These parameters must be (Red, Green, Blue) or
(Hue, Lightness, Saturation) depending on hls.
On some color terminals, colors collide with highlights. You can
register these collisions with the ncv capability. This is a bit-mask
of attributes not to be used when colors are enabled. The
correspondence with the attributes understood by curses is as follows:
Attribute Bit Decimal
A_STANDOUT 0 1
A_UNDERLINE 1 2
A_REVERSE 2 4
A_BLINK 3 8
A_DIM 4 16
A_BOLD 5 32
A_INVIS 6 64
A_PROTECT 7 128
A_ALTCHARSET 8 256
For example, on many IBM PC consoles, the underline attribute collides
with the foreground color blue and is not available in color mode.
These should have an ncv capability of 2.
SVr4 curses does nothing with ncv, ncurses recognizes it and optimizes
the output in favor of colors.
Miscellaneous
If the terminal requires other than a null (zero) character as a pad,
then this can be given as pad. Only the first character of the pad
string is used. If the terminal does not have a pad character, specify
npc. Note that ncurses implements the termcap-compatible PC variable;
though the application may set this value to something other than a
null, ncurses will test npc first and use napms if the terminal has no
pad character.
If the terminal can move up or down half a line, this can be indicated
with hu (half-line up) and hd (half-line down). This is primarily
useful for superscripts and subscripts on hard-copy terminals. If a
hard-copy terminal can eject to the next page (form feed), give this as
ff (usually control L).
If there is a command to repeat a given character a given number of
times (to save time transmitting a large number of identical
characters) this can be indicated with the parameterized string rep.
The first parameter is the character to be repeated and the second is
the number of times to repeat it. Thus, tparm(repeat_char, 'x', 10) is
the same as `xxxxxxxxxx'.
If the terminal has a settable command character, such as the TEKTRONIX
4025, this can be indicated with cmdch. A prototype command character
is chosen which is used in all capabilities. This character is given
in the cmdch capability to identify it. The following convention is
supported on some UNIX systems: The environment is to be searched for a
CC variable, and if found, all occurrences of the prototype character
are replaced with the character in the environment variable.
Terminal descriptions that do not represent a specific kind of known
terminal, such as switch, dialup, patch, and network, should include
the gn (generic) capability so that programs can complain that they do
not know how to talk to the terminal. (This capability does not apply
to virtual terminal descriptions for which the escape sequences are
known.)
If the terminal has a ``meta key'' which acts as a shift key, setting
the 8th bit of any character transmitted, this fact can be indicated
with km. Otherwise, software will assume that the 8th bit is parity and
it will usually be cleared. If strings exist to turn this ``meta
mode'' on and off, they can be given as smm and rmm.
If the terminal has more lines of memory than will fit on the screen at
once, the number of lines of memory can be indicated with lm. A value
of lm#0 indicates that the number of lines is not fixed, but that there
is still more memory than fits on the screen.
If the terminal is one of those supported by the UNIX virtual terminal
protocol, the terminal number can be given as vt.
Media copy strings which control an auxiliary printer connected to the
terminal can be given as mc0: print the contents of the screen, mc4:
turn off the printer, and mc5: turn on the printer. When the printer
is on, all text sent to the terminal will be sent to the printer. It
is undefined whether the text is also displayed on the terminal screen
when the printer is on. A variation mc5p takes one parameter, and
leaves the printer on for as many characters as the value of the
parameter, then turns the printer off. The parameter should not exceed
255. All text, including mc4, is transparently passed to the printer
while an mc5p is in effect.
Glitches and Braindamage
Hazeltine terminals, which do not allow `~' characters to be displayed
should indicate hz.
Terminals which ignore a line-feed immediately after an am wrap, such
as the Concept and vt100, should indicate xenl.
If el is required to get rid of standout (instead of merely writing
normal text on top of it), xhp should be given.
Teleray terminals, where tabs turn all characters moved over to blanks,
should indicate xt (destructive tabs). Note: the variable indicating
this is now `dest_tabs_magic_smso'; in older versions, it was
teleray_glitch. This glitch is also taken to mean that it is not
possible to position the cursor on top of a ``magic cookie'', that to
erase standout mode it is instead necessary to use delete and insert
line. The ncurses implementation ignores this glitch.
The Beehive Superbee, which is unable to correctly transmit the escape
or control C characters, has xsb, indicating that the f1 key is used
for escape and f2 for control C. (Only certain Superbees have this
problem, depending on the ROM.) Note that in older terminfo versions,
this capability was called `beehive_glitch'; it is now `no_esc_ctl_c'.
Other specific terminal problems may be corrected by adding more
capabilities of the form xx.
Similar Terminals
If there are two very similar terminals, one (the variant) can be
defined as being just like the other (the base) with certain
exceptions. In the definition of the variant, the string capability
use can be given with the name of the base terminal. The capabilities
given before use override those in the base type named by use. If there
are multiple use capabilities, they are merged in reverse order. That
is, the rightmost use reference is processed first, then the one to its
left, and so forth. Capabilities given explicitly in the entry
override those brought in by use references.
A capability can be canceled by placing xx@ to the left of the use
reference that imports it, where xx is the capability. For example,
the entry
2621-nl, smkx@, rmkx@, use=2621,
defines a 2621-nl that does not have the smkx or rmkx capabilities, and
hence does not turn on the function key labels when in visual mode.
This is useful for different modes for a terminal, or for different
user preferences.
Pitfalls of Long Entries
Long terminfo entries are unlikely to be a problem; to date, no entry
has even approached terminfo's 4096-byte string-table maximum.
Unfortunately, the termcap translations are much more strictly limited
(to 1023 bytes), thus termcap translations of long terminfo entries can
cause problems.
The man pages for 4.3BSD and older versions of tgetent() instruct the
user to allocate a 1024-byte buffer for the termcap entry. The entry
gets null-terminated by the termcap library, so that makes the maximum
safe length for a termcap entry 1k-1 (1023) bytes. Depending on what
the application and the termcap library being used does, and where in
the termcap file the terminal type that tgetent() is searching for is,
several bad things can happen.
Some termcap libraries print a warning message or exit if they find an
entry that's longer than 1023 bytes; others do not; others truncate the
entries to 1023 bytes. Some application programs allocate more than
the recommended 1K for the termcap entry; others do not.
Each termcap entry has two important sizes associated with it: before
"tc" expansion, and after "tc" expansion. "tc" is the capability that
tacks on another termcap entry to the end of the current one, to add on
its capabilities. If a termcap entry does not use the "tc" capability,
then of course the two lengths are the same.
The "before tc expansion" length is the most important one, because it
affects more than just users of that particular terminal. This is the
length of the entry as it exists in /etc/termcap, minus the
backslash-newline pairs, which tgetent() strips out while reading it.
Some termcap libraries strip off the final newline, too (GNU termcap
does not). Now suppose:
* a termcap entry before expansion is more than 1023 bytes long,
* and the application has only allocated a 1k buffer,
* and the termcap library (like the one in BSD/OS 1.1 and GNU) reads
the whole entry into the buffer, no matter what its length, to see
if it is the entry it wants,
* and tgetent() is searching for a terminal type that either is the
long entry, appears in the termcap file after the long entry, or
does not appear in the file at all (so that tgetent() has to
search the whole termcap file).
Then tgetent() will overwrite memory, perhaps its stack, and probably
core dump the program. Programs like telnet are particularly
vulnerable; modern telnets pass along values like the terminal type
automatically. The results are almost as undesirable with a termcap
library, like SunOS 4.1.3 and Ultrix 4.4, that prints warning messages
when it reads an overly long termcap entry. If a termcap library
truncates long entries, like OSF/1 3.0, it is immune to dying here but
will return incorrect data for the terminal.
The "after tc expansion" length will have a similar effect to the
above, but only for people who actually set TERM to that terminal type,
since tgetent() only does "tc" expansion once it is found the terminal
type it was looking for, not while searching.
In summary, a termcap entry that is longer than 1023 bytes can cause,
on various combinations of termcap libraries and applications, a core
dump, warnings, or incorrect operation. If it is too long even before
"tc" expansion, it will have this effect even for users of some other
terminal types and users whose TERM variable does not have a termcap
entry.
When in -C (translate to termcap) mode, the ncurses implementation of
tic(1) issues warning messages when the pre-tc length of a termcap
translation is too long. The -c (check) option also checks resolved
(after tc expansion) lengths.
Binary Compatibility
It is not wise to count on portability of binary terminfo entries
between commercial UNIX versions. The problem is that there are at
least two versions of terminfo (under HP-UX and AIX) which diverged
from System V terminfo after SVr1, and have added extension
capabilities to the string table that (in the binary format) collide
with System V and XSI Curses extensions.
EXTENSIONS
Some SVr4 curses implementations, and all previous to SVr4, do not
interpret the %A and %O operators in parameter strings.
SVr4/XPG4 do not specify whether msgr licenses movement while in an
alternate-character-set mode (such modes may, among other things, map
CR and NL to characters that do not trigger local motions). The
ncurses implementation ignores msgr in ALTCHARSET mode. This raises
the possibility that an XPG4 implementation making the opposite
interpretation may need terminfo entries made for ncurses to have msgr
turned off.
The ncurses library handles insert-character and insert-character modes
in a slightly non-standard way to get better update efficiency. See
the Insert/Delete Character subsection above.
The parameter substitutions for set_clock and display_clock are not
documented in SVr4 or the XSI Curses standard. They are deduced from
the documentation for the AT&T 505 terminal.
Be careful assigning the kmous capability. The ncurses wants to
interpret it as KEY_MOUSE, for use by terminals and emulators like
xterm that can return mouse-tracking information in the keyboard-input
stream.
Different commercial ports of terminfo and curses support different
subsets of the XSI Curses standard and (in some cases) different
extension sets. Here is a summary, accurate as of October 1995:
SVR4, Solaris, ncurses -- These support all SVr4 capabilities.
SGI -- Supports the SVr4 set, adds one undocumented extended string
capability (set_pglen).
SVr1, Ultrix -- These support a restricted subset of terminfo
capabilities. The booleans end with xon_xoff; the numerics with
width_status_line; and the strings with prtr_non.
HP/UX -- Supports the SVr1 subset, plus the SVr[234] numerics
num_labels, label_height, label_width, plus function keys 11 through
63, plus plab_norm, label_on, and label_off, plus some incompatible
extensions in the string table.
AIX -- Supports the SVr1 subset, plus function keys 11 through 63, plus
a number of incompatible string table extensions.
OSF -- Supports both the SVr4 set and the AIX extensions.
