Synopsis

   /usr/share/lib/terminfo/?/*

Description

This manual page describes the UNIX^® System V Release 4 terminfo database format used in prior versions of UnixWare. The default terminfo database format is described on terminfo(4) and complies with the X/Open Curses, Issue 4 Version 2 standard found in The Single UNIX^® Specification, Version 2.

terminfo is a database produced by tic that describes the capabilities of devices such as terminals and printers. Devices are described in terminfo source files by specifying a set of capabilities, by quantifying certain aspects of the device, and by specifying character sequences that affect particular results. This database is often used by screen oriented applications such as vi and curses programs, as well as by some UNIX system commands such as ls and more. This usage allows them to work with a variety of devices without changes to the programs.

terminfo source files consist of one or more device descriptions. Each description consists of a header (beginning in column 1) and one or more lines that list the features for that particular device. Every line in a terminfo source file must end in a comma (``,''). Every line in a terminfo source file except the header must be indented with one or more white spaces (either spaces or tabs).

Entries in terminfo source files consist of a number of comma-separated fields. White space after each comma is ignored. Embedded commas must be escaped by using a backslash. The following example shows the format of a terminfo source file.

   alias[1] | alias[2] | . . . | alias[n] | longname,
   <white space> am, lines #24,
   <white space> home=\Eeh,

The first line, commonly referred to as the header line, must begin in column one and must contain at least two aliases separated by vertical bars. The last field in the header line must be the long name of the device and it may contain any string. Alias names must be unique in the terminfo database and they must conform to UNIX system file naming conventions [see tic(1M)]; they cannot, for example, contain white space or slashes.

Every device must be assigned a name, such as vt100. Device names (except the long name) should be chosen using the following conventions. The name should not contain hyphens because hyphens are reserved for use when adding suffixes that indicate special modes.

These special modes may be modes that the hardware can be in, or user preferences. To assign a special mode to a particular device, append a suffix consisting of a hyphen and an indicator of the mode to the device name. For example, the -w suffix means ``wide mode''; when specified, it allows for a width of 132 columns instead of the standard 80 columns. Therefore, if you want to use a vt100 device set to wide mode, name the device vt100-w. Use the following suffixes where possible.

Suffix Meaning Example

-w Wide mode (more than 80 columns) 5410-w

-am With auto. margins (usually default) vt100-am

-nam Without automatic margins vt100-nam

-n Number of lines on the screen 2300-40

-na No arrow keys (leave them in local) c100-na

-np Number of pages of memory c100-4p

-rv Reverse video 4415-rv

Suffix	Meaning	Example
-w	Wide mode (more than 80 columns)	5410-w
-am	With auto. margins (usually default)	vt100-am
-nam	Without automatic margins	vt100-nam
-n	Number of lines on the screen	2300-40
-na	No arrow keys (leave them in local)	c100-na
-np	Number of pages of memory	c100-4p
-rv	Reverse video	4415-rv

The terminfo reference manual page is organized in two sections: ``DEVICE CAPABILITIES'' and ``PRINTER CAPABILITIES.''

PART 1: DEVICE CAPABILITIES

Capabilities in terminfo are of three types: Boolean capabilities (which show that a device has or does not have a particular feature), numeric capabilities (which quantify particular features of a device), and string capabilities (which provide sequences that can be used to perform particular operations on devices).

In the following table, a Variable is the name by which a C programmer accesses a capability (at the terminfo level). A Capname is the short name for a capability specified in the terminfo source file. It is used by a person updating the source file and by the tput command. A Termcap Code is a two-letter sequence that corresponds to the termcap capability name. (Note that termcap is no longer supported.)

Capability names have no real length limit, but an informal limit of five characters has been adopted to keep them short. Whenever possible, capability names are chosen to be the same as or similar to those specified by the ANSI X3.64-1979 standard. Semantics are also intended to match those of the ANSI standard.

All string capabilities listed below may have padding specified, with the exception of those used for input. Input capabilities, listed under the ``Strings'' section in the following tables, have names beginning with key_. The ``#i'' symbol in the description field of the following tables refers to the ith parameter.

Types of Capabilities in the Sample Entry

The sample entry shows the formats for the three types of terminfo capabilities listed: Boolean, numeric, and string. All capabilities specified in the terminfo source file must be followed by commas, including the last capability in the source file. In terminfo source files, capabilities are referenced by their capability names (as shown in the previous tables).

Boolean capabilities are specified simply by their comma separated Capnames.

Numeric capabilities are followed by the character `#' and then a positive integer value. (Values for numeric capabilities may be specified in decimal, octal, or hexadecimal, using normal C programming language conventions.)

Finally, string-valued capabilities such as el (clear to end of line sequence) are listed by a two- to five-character capname, an `=', and a string ended by the next occurrence of a comma. A delay in milliseconds may appear anywhere in such a capability, preceded by ``$'' and enclosed in angle brackets, as in el=\EK$<3>. Padding characters are supplied by tput. The delay can be any of the following: a number, a number followed by an asterisk, such as 5*, a number followed by a slash, such as 5/, or a number followed by both, such as 5*/. A ``*'' shows 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 characters, the factor is still the number of lines affected. This is always 1 unless the device has in and the software uses it.) When a ``*'' is specified, it is sometimes useful to give a delay of the form 3.5 to specify a delay per unit to tenths of milliseconds. (Only one decimal place is allowed.)

A `/' indicates that the padding is mandatory. If a device has xon defined, the padding information is advisory and will only be used for cost estimates or when the device is in raw mode. Mandatory padding will be transmitted regardless of the setting of xon. If padding (whether advisory or mandatory) is specified for bel or flash, however, it will always be used, regardless of whether xon is specified.

terminfo offers notation for encoding special characters. 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, and \s give a newline, linefeed, return, tab, backspace, formfeed, and space, respectively. Other escapes include: \^ for caret (^); \\ for backslash (\); \, for comma (,); \: for colon (:); and \0 for null. (\0 will actually produce \200, which does not terminate a string but behaves as a null character on most devices, providing CS7 is specified. [See stty(1).] Finally, characters may be given as three octal digits after a backslash (for example, \123).

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. Note that capabilities are defined in a left-to-right order and, therefore, a prior definition will override a later definition.

Preparing Descriptions

The most effective way to prepare a device description is by imitating the description of a similar device in terminfo and building up a description gradually, using partial descriptions with vi to check that they are correct. Be aware that a very unusual device may expose deficiencies in the ability of the terminfo file to describe it or the inability of vi to work with that device. To test a new device description, set the environment variable TERMINFO to the pathname of a directory containing the compiled description you are working on and programs will look there rather than in /usr/share/lib/terminfo. To get the padding for insert-line correct (if the device manufacturer did not document it) a severe test is to comment out xon, edit a large file at 9600 baud with vi, delete 16 or so lines from the middle of the screen, and then press the u key several times quickly. If the display is corrupted, more padding is usually needed. A similar test can be used for insert-character.

Section 1-1: Basic Capabilities

The number of columns on each line for the device is given by the cols numeric capability. If the device has a screen, then the number of lines on the screen is given by the lines capability. If the device 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 device is a printing terminal, with no soft copy unit, specify both hc and os. If there is a way to move the cursor to the left edge of the current row, specify this as cr. (Normally this will be carriage return, control M.) If there is a way to produce an audible signal (such as a bell or a beep), specify it as bel. If, like most devices, the device uses the xon-xoff flow-control protocol, specify xon.

If there is a way to move the cursor one position to the left (such as backspace), that capability should be given as cub1. Similarly, sequences to move to the right, up, and down should be given as cuf1, cuu1, and cud1, respectively. These local cursor motions must not alter the text they pass over; for example, you would not normally use ``cuf1=\s'' 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 screen terminal. Programs should never attempt to backspace around the left edge, unless bw is specified, and should never attempt to go up locally off the top. To scroll text up, a program goes to the bottom left corner of the screen and sends 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. These versions have the same semantics as ind and ri, except that they take one parameter and scroll the number of lines specified by that parameter. 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. Backward motion from the left edge of the screen is possible only when bw is specified. In this case, cub1 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 device has switch selectable automatic margins, am should be specified in the terminfo source file. In this case, initialization strings should turn on this option, if possible. If the device has a command that 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 device 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 hardcopy and screen terminals. Thus the AT&T 5320 hardcopy terminal is described as follows:

      5320|att5320|AT&T 5320 hardcopy terminal,
   	  am, hc, os,
   	  cols#132,
   	  bel=^G, cr=\r, cub1=\b, cnd1=\n,
   	  dch1=\E[P, dl1=\E[M,
   	  ind=\n,

while the Lear Siegler ADM-3 is described as

      adm3|lsi adm3,
      am, bel=^G, clear=^Z, cols#80, cr=^M, cub1=^H,
      cud1=^J, ind=^J, lines#24,

Section 1-2: Parameterized Strings

Cursor addressing and other strings requiring parameters are described by a parameterized string capability, with printf-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 the stack in the manner of Reverse Polish Notation (postfix). Typically a sequence will push one of the parameters onto the stack and then print it in some format. Often more complex operations are necessary. Operations are in postfix form with the operands in the usual order. That is, to subtract 5 from the first parameter, one would use %p1%{5}%-.

The % encodings have the following meanings:

%%

outputs `%'

%[[:]flags][width[.precision]][doxXs]

as in printf, flags are [-+#] and space

%c

print pop gives %c

%p[1-9]

push ith parm

%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

%'c'

push char constant c

%{nn}

push decimal constant nn

%l

push strlen(pop)

%+ %- %* %/ %m

arithmetic (%m is mod): push(pop integer[2] op pop integer[1]) where integer[1] is the top of the stack

%& %| %^

bit operations: push(pop integer[2] op pop integer[1])

%= %> %<

logical operations: push(pop integer[2] op pop integer[1])

%A %O

logical operations: and, or

%! %~

unary operations: push(op pop)

%i

(for ANSI terminals) add 1 to first parm, if one parm present, or first two parms, if more than one parm present

%? expr %t thenpart %e elsepart %;

if-then-else; %e elsepart is optional; else-if's are possible ala Algol 68:

   %? c[1] %t b[1] %e c[2] %t b[2] %e c[3] %t b[3] %e c[4] %t b[4] %e b[5]%;

c[i] are conditions, b[i] are bodies.

If the ``-'' flag is used with ``%[doxXs]'', then a colon (:) must be placed between the ``%'' and the ``-'' to differentiate the flag from the binary ``%-'' operator, for example, ``%:-16.16s''.

Consider the Hewlett-Packard 2645, 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 zero-padded as two digits. Thus its cup capability is:

   cup=\E&a%p2%2.2dc%p1%2.2dY$<6>

The Micro-Term 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''. Devices that 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%'\s'%+%c%p2%'\s'%+%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.

Section 1-3: 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 Hewlett-Packard terminals cannot be used for home without losing some of the other features on the terminal.)

If the device 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 Hewlett-Packard 2645) and can be used in preference to cup. If there are parameterized local motions (for example, 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 device does not have cup, such as the Tektronix 4025.

If the device 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, such as the Concept, with more than one page of memory. If the device has only memory relative cursor addressing and not screen relative cursor addressing, a one screen-sized window must be fixed into the device 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.

Section 1-4: 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.)

Section 1-5: Insert/Delete Line

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 destructive 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 this command -- the sc and rc (save and restore cursor) commands are also useful. 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.

To determine whether a terminal has destructive scrolling regions or non-destructive scrolling regions, create a scrolling region in the middle of the screen, place data on the bottom line of the scrolling region, move the cursor to the top line of the scrolling region, and do a reverse index (ri) followed by a delete line (dl1) or index (ind). If the data that was originally on the bottom line of the scrolling region was restored into the scrolling region by the dl1 or ind, then the terminal has non-destructive scrolling regions. Otherwise, it has destructive scrolling regions. Do not specify csr if the terminal has non-destructive scrolling regions, unless ind,
