NAME
terminfo - terminal capability data base
SYNOPSIS
/opt/sfw/share/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(3X). Terminfo describes terminals
by giving a set of capabilities which they have, by specify-
ing how to perform screen operations, and by specifying pad-
ding requirements and initialization sequences.
Entries in terminfo consist of a sequence of `,' separated
fields (embedded commas may be escaped with a backslash or
notated as \072). White space after the `,' separator is
ignored. The first entry for each terminal gives the names
which are known for the terminal, separated by `|' charac-
ters. 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 under-
stood 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.
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 prefer-
ences, 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 data-
base, and is used by a person updating the database. When-
ever 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 specifica-
tion.
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 seman-
tics 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
(#i) indicates the ith parameter.
These are the boolean capabilities:
