NAME

terminfo - terminal capability data base 

SYNOPSIS

/usr/share/terminfo/*/* 

DESCRIPTION

Terminfois a data base describing terminals, used by screen-oriented programs such asnvi(1),rogue(1)and libraries such ascurses(3X).Terminfodescribes terminals by giving a set of capabilities which theyhave, by specifying how to perform screen operations, and byspecifying padding requirements and initialization sequences.

Entries interminfoconsist of a sequence of `,' separated fields (embedded commas may beescaped 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 theterminal, 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 captoinfoand 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) shouldbe chosen using the following conventions.The particular piece of hardware making up the terminal shouldhave a root name, thus ``hp2621''.This name should not contain hyphens.Modes that the hardware can be in, or user preferences, shouldbe 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:

SuffixMeaningExample
-nnNumber of lines on the screenaaa-60
-npNumber of pages of memoryc100-4p
-amWith automargins (usually the default)vt100-am
-mMono mode; suppress color ansi-m
-mcMagic cookie; spaces when highlightingwy30-mc
-naNo arrow keys (leave them in local)c100-na
-namWithout automatic margins vt100-nam
-nlNo status line att4415-nl
-nsNo status line hp2626-ns
-rvReverse video c100-rv
-sEnable status line vt100-s
-vbUse visible bell instead of beepwy370-vb
-wWide 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 aterminfo description block and available to terminfo-using code. In eachline 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 tothe ANSI X3.64-1979 standard (now superseded by ECMA-48, which usesidentical or very similar names). Semantics are also intended to matchthose of the specification.

The termcap code is the oldtermcapcapability name (some capabilities are new, and have names which termcapdid not originate).Capability names have no hard length limit, but an informal limit of 5characters has been adopted to keep them short and to allow the tabs inthe source fileCapsto line up nicely.

Finally, the description field attempts to convey the semantics of thecapability. 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 withparms as given (#i).
(P*)
indicates that padding may vary in proportion to the number oflines affected
(#i)
indicates the ith parameter.

These are the boolean capabilities:

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

Entries may continue onto multiple lines by placing white space atthe beginning of each line except the first.Comments may be included on lines beginning with ``#''.Capabilities interminfoare of three types:Boolean capabilities which indicate that the terminal hassome particular feature, numeric capabilities giving the size of the terminalor the size of particular delays, and stringcapabilities, which give a sequence which can be used to perform particularterminal operations.

 

Types of Capabilities

All capabilities have names.For instance, the fact thatANSI-standard terminals haveautomatic margins(i.e., an automatic return and line-feedwhen 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 linesequence) are given by the two-character code, an `=', and then a stringending at the next following `,'.

A number of escape sequences are provided in the string valued capabilitiesfor easy encoding of characters there.Both \E and \emap to an ESCAPE character,^x maps to a control-x for any appropriate x, and the sequences\n \l \r \t \b \f \s givea 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 behavesas 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 bytputsto provide this delay.The delay must be a number with at most one decimalplace of precision; it may be followed by suffixes `*' or '/' or both.A `*'indicates that the padding required is proportional to the number of linesaffected by the operation, and the amount given is the per-affected-unitpadding required.(In the case of insert character, the factor is still thenumber oflinesaffected.) Normally, padding is advisory if the device has the xoncapability; 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 givennumber of milliseconds even on devices for which xon is present toindicate flow control.

Sometimes individual capabilities must be commented out.To do this, put a period before the capability name.For example, see the secondindin the example above.

 

Fetching Compiled Descriptions

If the environment variable TERMINFO is set, it is interpreted as the pathnameof a directory containing the compiled description you are working on.Onlythat directory is searched.

If TERMINFO is not set, the ncurses version of the terminfo reader codewill instead look in the directory $HOME/.terminfofor a compiled description.If it fails to find one there, and the environment variable TERMINFO_DIRS isset, it will interpret the contents of that variable as a list of colon-separated directories to be searched (an empty entry is interpreted as acommand to search /usr/share/terminfo).If no description is found in any of theTERMINFO_DIRS directories, the fetch fails.

If neither TERMINFO nor TERMINFO_DIRS is set, the last place tried will be thesystem terminfo directory, /usr/share/terminfo.

(Neither the $HOME/.terminfo lookups nor TERMINFO_DIRS extensions aresupported 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 imitatingthe description of a similar terminal interminfoand to build up a description gradually, using partial descriptionswithvior some other screen-oriented program to check that they are correct.Be aware that a very unusual terminal may expose deficiencies inthe ability of theterminfofile to describe itor bugs in the screen-handling code of the test program.

To get the padding for insert line right (if the terminal manufacturerdid 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 thecols numeric capability.If the terminal is a CRT, then thenumber of lines on the screen is given by the lines capability.If the terminal wraps around to the beginning of the next line whenit reaches the right margin, then it should have the am capability.If the terminal can clear its screen, leaving the cursor in the homeposition, 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 bothhcandos.(osapplies to storage scope terminals, such as TEKTRONIX 4010series, as well as hard copy and APL terminals.)If there is a code to move the cursor to the left edge of the currentrow, give this ascr.(Normally this will be carriage return, control M.)If there is a code to produce an audible signal (bell, beep, etc)give this asbel.

If there is a code to move the cursor one position to the left(such as backspace) that capability should be given ascub1.Similarly, codes to move to the right, up, and down should begiven ascuf1,cuu1,andcud1.These local cursor motions should not alter the text they pass over,for example, you would not normally use `cuf1= ' because thespace would erase the character moved over.

A very important point here is that the local cursor motions encodedinterminfoare undefined at the
