<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 5.5 (patch 20061209).
-
- 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 <EM>captoinfo</EM> and <EM>infotocap</EM> (aliases for <EM>tic</EM>)
- 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 <EM>infocmp</EM> <EM>-f</EM> option relies on this to format
- if-then-else expressions: the result can be read by <EM>tic</EM>.
+ 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
piece of hardware making up the terminal should have a
- root name, thus ``hp2621''. This name should not contain
+ root name, thus "hp2621". This name should not contain
hyphens. Modes that the hardware can be in, or user pref-
erences, 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 pos-
sible:
-
<STRONG>Suffix</STRONG> <STRONG>Meaning</STRONG> <STRONG>Example</STRONG>
-<EM>nn</EM> Number of lines on the screen aaa-60
-<EM>n</EM>p Number of pages of memory c100-4p
-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 <STRONG>term(7)</STRONG>
manual page.
- <STRONG>Capabilities</STRONG>
- 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.

+ The preceding section listed the <EM>predefined</EM> capabilities.
+ They deal with some special features for terminals no
+ longer (or possibly never) produced. Occasionally there
+ are special features of newer terminals which are awkward
+ or impossible to represent by reusing the predefined capa-
+ bilities.
+
+ <STRONG>ncurses</STRONG> addresses this limitation by allowing user-defined
+ capabilities. The <STRONG>tic</STRONG> and <STRONG>infocmp</STRONG> programs provide the <STRONG>-x</STRONG>
+ option for this purpose. When <STRONG>-x</STRONG> is set, <STRONG>tic</STRONG> treats
+ unknown capabilities as user-defined. That is, if <STRONG>tic</STRONG>
+ encounters a capability name which it does not recognize,
+ it infers its type (boolean, number or string) from the
+ syntax and makes an extended table entry for that capabil-
+ ity. The <STRONG><A HREF="curs_extend.3x.html">use_extended_names(3x)</A></STRONG> function makes this
+ information conditionally available to applications. The
+ ncurses library provides the data leaving most of the
+ behavior to applications:
+
+ <STRONG>o</STRONG> User-defined capability strings whose name begins with
+ "k" are treated as function keys.
+
+ <STRONG>o</STRONG> The types (boolean, number, string) determined by <STRONG>tic</STRONG>
+ can be inferred by successful calls on <STRONG>tigetflag</STRONG>, etc.
+
+ <STRONG>o</STRONG> If the capability name happens to be two characters,
+ the capability is also available through the termcap
+ interface.
+
+ While termcap is said to be extensible because it does not
+ use a predefined set of capabilities, in practice it has
+ been limited to the capabilities defined by terminfo
+ implementations. As a rule, user-defined capabilities
+ intended for use by termcap applications should be limited
+ to booleans and numbers to avoid running past the 1023
+ byte limit assumed by termcap implementations and their
+ applications. In particular, providing extended sets of
+ function keys (past the 60 numbered keys and the handful
+ of special named keys) is best done using the longer names
+ available using terminfo.

- 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 <EM>lines</EM>
- affected.) Normally, padding is advisory if the device
- has the <STRONG>xon</STRONG> 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 <STRONG>xon</STRONG> is

- 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
- 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
