<EM>Terminfo</EM> is a data base describing terminals, used by
- screen-oriented programs such as <STRONG><A HREF="nvi.1.html">nvi(1)</A></STRONG>, <STRONG><A HREF="rogue.1.html">rogue(1)</A></STRONG> and
+ screen-oriented programs such as <STRONG>nvi(1)</STRONG>, <STRONG>rogue(1)</STRONG> and
libraries such as <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>. <EM>Terminfo</EM> describes termi-
nals by giving a set of capabilities which they have, by
specifying how to perform screen operations, and by speci-
fying padding requirements and initialization sequences.
- This describes <STRONG>ncurses</STRONG> version 5.9 (patch 20130309).
-
- Entries in <EM>terminfo</EM> 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 <STRONG>captoinfo</STRONG> and <STRONG>infotocap</STRONG> (aliases for <STRONG>tic</STRONG>)
- 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 <STRONG>infocmp</STRONG> <STRONG>-f</STRONG> option relies on this to format
- if-then-else expressions: the result can be read by <STRONG>tic</STRONG>.
+ This describes <STRONG>ncurses</STRONG> version 6.0 (patch 20170429).

+</PRE><H3><a name="h3-Terminfo-Entry-Syntax">Terminfo Entry Syntax</a></H3><PRE>
+ Entries in <EM>terminfo</EM> consist of a sequence of fields:
+
+ <STRONG>o</STRONG> Each field ends with a comma "," (embedded commas may
+ be escaped with a backslash or written as "\054").
+
+ <STRONG>o</STRONG> White space between fields is ignored.
+
+ <STRONG>o</STRONG> The first field in a <EM>terminfo</EM> entry begins in the
+ first column.
+
+ <STRONG>o</STRONG> Newlines and leading whitespace (spaces or tabs) may
+ be used for formatting entries for readability. These
+ are removed from parsed entries.
+
+ The <STRONG>infocmp</STRONG> <STRONG>-f</STRONG> and <STRONG>-W</STRONG> options rely on this to format
+ if-then-else expressions, or to enforce maximum line-
+ width. The resulting formatted terminal description
+ can be read by <STRONG>tic</STRONG>.
+
+ <STRONG>o</STRONG> The first field 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 (its primary name), the last name
+ given should be a long name fully identifying the ter-
+ minal (see <STRONG><A HREF="curs_termattrs.3x.html">longname(3x)</A></STRONG>), and all others are treated
+ as synonyms (aliases) for the primary terminal name.
+
+ X/Open Curses advises that 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.
+
+ This implementation is not so strict; it allows mixed
+ case in the primary name and aliases. If the last
+ name has no embedded blanks, it allows that to be both
+ an alias and a verbose name (but will warn about this
+ ambiguity).
+
+ <STRONG>o</STRONG> Lines beginning with a "#" in the first column are
+ treated as comments.
+
+ While comment lines are legal at any point, the output
+ of <STRONG>captoinfo</STRONG> and <STRONG>infotocap</STRONG> (aliases for <STRONG>tic</STRONG>) will move
+ comments so they occur only between entries.
Terminal names (except for the last, verbose entry) should
be chosen using the following conventions. The particular
-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

- The following is a complete table of the capabilities
- included in a terminfo description block and available to
+
+</PRE><H3><a name="h3-Terminfo-Capabilities-Syntax">Terminfo Capabilities Syntax</a></H3><PRE>
+ The terminfo entry consists of several <EM>capabilities</EM>, i.e.,
+ features that the terminal has, or methods for exercising
+ the terminal's features.
+
+ After the first field (giving the name(s) of the terminal
+ entry), there should be one or more <EM>capability</EM> fields.
+ These are boolean, numeric or string names with corre-
+ sponding values:
+
+ <STRONG>o</STRONG> Boolean capabilities are true when present, false when
+ absent. There is no explicit value for boolean capa-
+ bilities.
+
+ <STRONG>o</STRONG> Numeric capabilities have a "#" following the name,
+ then an unsigned decimal integer value.
+
+ <STRONG>o</STRONG> String capabilities have a "=" following the name,
+ then an string of characters making up the capability
+ value.
+
+ String capabilities can be split into multiple lines,
+ just as the fields comprising a terminal entry can be
+ split into multiple lines. While blanks between
+ fields are ignored, blanks embedded within a string
+ value are retained, except for leading blanks on a
+ line.
+
+ Any capability can be <EM>canceled</EM>, i.e., suppressed from the
+ terminal entry, by following its name with "@" rather than
+ a capability value.
+
+
+</PRE><H3><a name="h3-Similar-Terminals">Similar Terminals</a></H3><PRE>
+ 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 vari-
+ ant, the string capability <STRONG>use</STRONG> can be given with the name
+ of the base terminal:
+
+ <STRONG>o</STRONG> The capabilities given before <STRONG>use</STRONG> override those in
+ the base type named by <STRONG>use</STRONG>.
+
+ <STRONG>o</STRONG> If there are multiple <STRONG>use</STRONG> capabilities, they are
+ merged in reverse order. That is, the rightmost <STRONG>use</STRONG>
+ reference is processed first, then the one to its
+ left, and so forth.
+
+ <STRONG>o</STRONG> Capabilities given explicitly in the entry override
+ those brought in by <STRONG>use</STRONG> references.
+
+ A capability can be canceled by placing <STRONG>xx@</STRONG> to the left of
+ the use reference that imports it, where <EM>xx</EM> is the capa-
+ bility. For example, the entry
+
+ 2621-nl, smkx@, rmkx@, use=2621,
+
+ defines a 2621-nl that does not have the <STRONG>smkx</STRONG> or <STRONG>rmkx</STRONG>
+ 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.
+
+ An entry included via <STRONG>use</STRONG> can contain canceled capabili-
+ ties, which have the same effect as if those cancels were
+ inline in the using terminal entry.

- 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

- <STRONG>Similar</STRONG> <STRONG>Terminals</STRONG>
- 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 vari-
- ant, the string capability <STRONG>use</STRONG> can be given with the name
- of the base terminal. The capabilities given before <STRONG>use</STRONG>
- override those in the base type named by <STRONG>use</STRONG>. If there
- are multiple <STRONG>use</STRONG> capabilities, they are merged in reverse
- order. That is, the rightmost <STRONG>use</STRONG> reference is processed
- first, then the one to its left, and so forth. Capabili-
- ties given explicitly in the entry override those brought
- in by <STRONG>use</STRONG> references.

- A capability can be canceled by placing <STRONG>xx@</STRONG> to the left of

- bility. For example, the entry
-
- 2621-nl, smkx@, rmkx@, use=2621,
-
- defines a 2621-nl that does not have the <STRONG>smkx</STRONG> or <STRONG>rmkx</STRONG>
- capabilities, and hence does not turn on the function key

+</PRE><H3><a name="h3-Pitfalls-of-Long-Entries">Pitfalls of Long Entries</a></H3><PRE>
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 transla-
termcap translations of long terminfo entries can cause
problems.
- The man pages for 4.3BSD and older versions of <STRONG>tgetent()</STRONG>
+ The man pages for 4.3BSD and older versions of <STRONG>tgetent</STRONG>
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

Some termcap libraries print a warning message or exit if
one, because it affects more than just users of that par-
ticular terminal. This is the length of the entry as it
exists in /etc/termcap, minus the backslash-newline pairs,
- which <STRONG>tgetent()</STRONG> strips out while reading it. Some termcap
