-<H2>DESCRIPTION</H2><PRE>
- <EM>Terminfo</EM> is a data base describing terminals, used by
- 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 20131221).
-
- 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>.
-
- 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 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
- -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 (&gt; 80 columns, usually 132) vt100-w
-
- For more on terminal naming conventions, see the <STRONG>term(7)</STRONG>
- manual page.

- <STRONG>Predefined</STRONG> <STRONG>Capabilities</STRONG>
- 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 <STRONG>variable</STRONG> is the name by which the programmer (at the
- terminfo level) accesses the capability.
-
- The <STRONG>capname</STRONG> 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 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 specifi-
- cation.
-
- The termcap code is the old <STRONG>termcap</STRONG> capability name (some
- capabilities are new, and have names which termcap did not
- originate).
-
- Capability names have no hard length limit, but an infor-
- mal limit of 5 characters has been adopted to keep them
- short and to allow the tabs in the source file <STRONG>Caps</STRONG> to
- line up nicely.
-
- Finally, the description field attempts to convey the
- semantics of the capability. You may find some codes in
- the description field:
+</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
+ <EM>Terminfo</EM> is a data base describing terminals, used by screen-oriented
+ programs such as <STRONG>nvi(1)</STRONG>, <STRONG>lynx(1)</STRONG>, <STRONG>mutt(1)</STRONG>, and other curses applica-
+ tions, using high-level calls to libraries such as <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>. It is
+ also used via low-level calls by non-curses applications which may be
+ screen-oriented (such as <STRONG><A HREF="clear.1.html">clear(1)</A></STRONG>) or non-screen (such as <STRONG><A HREF="tabs.1.html">tabs(1)</A></STRONG>).
+
+ <EM>Terminfo</EM> describes terminals by giving a set of capabilities which they
+ have, by specifying how to perform screen operations, and by specifying
+ padding requirements and initialization sequences.
+
+ This manual describes <STRONG>ncurses</STRONG> version 6.1 (patch 20200118).
+
+
+</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 for-
+ matted 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 termi-
+ nal (its primary name), the last name given should be a long name
+ fully identifying the terminal (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 com-
+ ments.
+
+ 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 mak-
+ ing 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
+ preferences, should be indicated by appending a hyphen and a mode suf-
+ fix. Thus, a vt100 in 132-column mode would be vt100-w. The following
+ suffixes should be used where possible:
+
+ <STRONG>Suffix</STRONG> <STRONG>Meaning</STRONG> <STRONG>Example</STRONG>
+ -<EM>nn</EM> Number of lines on the screen aaa-60

+
+
+</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 fea-
+ tures.
+
+ 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 corresponding values:
+
+ <STRONG>o</STRONG> Boolean capabilities are true when present, false when absent.
+ There is no explicit value for boolean capabilities.
+
+ <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 excep-
+ tions. In the definition of the variant, 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 ref-
+ erence that imports it, where <EM>xx</EM> is the capability. 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 capabilities, which have
+ the same effect as if those cancels were inline in the using terminal
+ entry.

- The XSI Curses standard added these hardcopy capabili-
- ties. They were used in some post-4.1 versions of System
- V curses, e.g., Solaris 2.5 and IRIX 6.x. Except for <STRONG>YI</STRONG>,
- the <STRONG>ncurses</STRONG> termcap names for them are invented. Accord-
- ing to the XSI Curses standard, they have no termcap
- names. If your compiled terminfo entries use these, they
- may not be binary-compatible with System V terminfo
- entries after SVr4.1; beware!

- <STRONG>User-Defined</STRONG> <STRONG>Capabilities</STRONG>
- 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>use_extended_names</STRONG> function makes this informa-
- tion 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.
-
- <STRONG>A</STRONG> <STRONG>Sample</STRONG> <STRONG>Entry</STRONG>

+ 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
+ capabilities.
+
+ <STRONG>ncurses</STRONG> addresses this limitation by allowing user-defined capabili-
+ ties. The <STRONG>tic</STRONG> and <STRONG>infocmp</STRONG> programs provide the <STRONG>-x</STRONG> option for this pur-
+ pose. 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 recog-
+ nize, it infers its type (boolean, number or string) from the syntax
+ and makes an extended table entry for that capability. 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 leav-
+ ing 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 prede-
+ fined set of capabilities, in practice it has been limited to the capa-
+ bilities 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 particu-
+ lar, 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.

- <STRONG>Preparing</STRONG> <STRONG>Descriptions</STRONG>
- We now outline how to prepare descriptions of terminals.
- The most effective way to prepare a terminal description
- is by imitating the description of a similar terminal in
- <EM>terminfo</EM> and to build up a description gradually, using
- partial descriptions with <EM>vi</EM> or some other screen-oriented
- program to check that they are correct. Be aware that a
- very unusual terminal may expose deficiencies in the abil-
- ity of the <EM>terminfo</EM> file to describe it or bugs in the
- screen-handling code of the test program.
-
- To get the padding for insert line right (if the terminal
- manufacturer did 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 usu-
- ally needed. A similar test can be used for insert char-
- acter.
-
- <STRONG>Basic</STRONG> <STRONG>Capabilities</STRONG>
- The number of columns on each line for the terminal is
- given by the <STRONG>cols</STRONG> numeric capability. If the terminal is
- a CRT, then the number of lines on the screen is given by
- the <STRONG>lines</STRONG> capability. If the terminal wraps around to the
- beginning of the next line when it reaches the right mar-
- gin, then it should have the <STRONG>am</STRONG> capability. If the termi-
- nal can clear its screen, leaving the cursor in the home
- position, then this is given by the <STRONG>clear</STRONG> string capabil-
- ity. If the terminal overstrikes (rather than clearing a
- position when a character is struck over) then it should
- have the <STRONG>os</STRONG> capability. If the terminal is a printing
- terminal, with no soft copy unit, give it both <STRONG>hc</STRONG> and <STRONG>os</STRONG>.
- (<STRONG>os</STRONG> applies to storage scope terminals, such as TEKTRONIX
- 4010 series, as well as hard copy and APL terminals.) If
- there is a code to move the cursor to the left edge of the
- current row, give this as <STRONG>cr</STRONG>. (Normally this will be car-
- riage return, control M.) If there is a code to produce
- an audible signal (bell, beep, etc) give this as <STRONG>bel</STRONG>.
-
- If there is a code to move the cursor one position to the
- left (such as backspace) that capability should be given
- as <STRONG>cub1</STRONG>. Similarly, codes to move to the right, up, and
- down should be given as <STRONG>cuf1</STRONG>, <STRONG>cuu1</STRONG>, and <STRONG>cud1</STRONG>. These local
- cursor motions should not alter the text they pass over,
- for example, you would not normally use "<STRONG>cuf1</STRONG>= " because
- the space would erase the character moved over.
-
- A very important point here is that the local cursor
- motions encoded in <EM>terminfo</EM> are undefined at the left and
- top edges of a CRT terminal. Programs should never
- attempt to backspace around the left edge, unless <STRONG>bw</STRONG> is
- given, and never attempt to go up locally off the top. In
- order to scroll text up, a program will go to the bottom
- left corner of the screen and send the <STRONG>ind</STRONG> (index) string.
-
- To scroll text down, a program goes to the top left corner
- of the screen and sends the <STRONG>ri</STRONG> (reverse index) string.
- The strings <STRONG>ind</STRONG> and <STRONG>ri</STRONG> are undefined when not on their
- respective corners of the screen.
-
- Parameterized versions of the scrolling sequences are <STRONG>indn</STRONG>
- and <STRONG>rin</STRONG> which have the same semantics as <STRONG>ind</STRONG> and <STRONG>ri</STRONG> except
- that they take one parameter, and scroll that many lines.
- They are also undefined except at the appropriate edge of
- the screen.
-
- The <STRONG>am</STRONG> 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 <STRONG>cuf1</STRONG> from the last column.
- The only local motion which is defined from the left edge
- is if <STRONG>bw</STRONG> is given, then a <STRONG>cub1</STRONG> from the left edge will
- move to the right edge of the previous row. If <STRONG>bw</STRONG> is not
- given, the effect is undefined. This is useful for draw-
- ing a box around the edge of the screen, for example. If
- the terminal has switch selectable automatic margins, the
- <EM>terminfo</EM> file usually assumes that this is on; i.e., <STRONG>am</STRONG>.
- If the terminal has a command which moves to the first
- column of the next line, that command can be given as <STRONG>nel</STRONG>
- (newline). It does not matter if the command clears the
- remainder of the current line, so if the terminal has no
- <STRONG>cr</STRONG> and <STRONG>lf</STRONG> it may still be possible to craft a working <STRONG>nel</STRONG>
- out of one or both of them.
-
- These capabilities suffice to describe hard-copy and
- "glass-tty" terminals. Thus the model 33 teletype is
- described as
+ <STRONG>o</STRONG> a list of directories (/usr/local/ncurses/share/ter-
+ minfo:/usr/share/terminfo), and
+
+ <STRONG>o</STRONG> the system terminfo directory, <EM>/usr/share/terminfo</EM> (the com-
+ piled-in default).

- adds them (pushing the sum on the stack in place of the

- with <STRONG>cuu1</STRONG> from the home position, but a program should
- never do this itself (unless <STRONG>ll</STRONG> 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 HP terminals
- cannot be used for <STRONG>home</STRONG>.)
-
- If the terminal has row or column absolute cursor address-
- ing, these can be given as single parameter capabilities
- <STRONG>hpa</STRONG> (horizontal position absolute) and <STRONG>vpa</STRONG> (vertical posi-
- tion absolute). Sometimes these are shorter than the more
- general two parameter sequence (as with the hp2645) and
- can be used in preference to <STRONG>cup</STRONG>. If there are parameter-

- these can be given as <STRONG>cud</STRONG>, <STRONG>cub</STRONG>, <STRONG>cuf</STRONG>, and <STRONG>cuu</STRONG> with a single
- parameter indicating how many spaces to move. These are

- <STRONG>Insert/Delete</STRONG> <STRONG>Character</STRONG>
- There are two basic kinds of intelligent terminals with
- respect to insert/delete character which can be described
- using <EM>terminfo.</EM> The most common insert/delete character
- operations affect only the characters on the current line
- and shift characters off the end of the line rigidly.
- Other terminals, such as the Concept 100 and the Perkin
- Elmer Owl, make a distinction between typed and untyped
- blanks on the screen, shifting upon an insert or delete
- only to an untyped blank on the screen which is either
- eliminated, or expanded to two untyped blanks.
-
- You can determine the kind of terminal you have by clear-
- ing the screen and then typing text separated by cursor
- motions. Type "abc def" using local cursor motions
- (not spaces) between the "abc" and the "def". Then posi-
- tion the cursor before the "abc" and put the terminal in
- insert mode. If typing characters causes the rest of the
- line to shift rigidly and characters to fall off the end,
- then your terminal does not distinguish between blanks and
- untyped positions. If the "abc" shifts over to the "def"
- which then move together around the end of the current
- line and onto the next as you insert, you have the second
- type of terminal, and should give the capability <STRONG>in</STRONG>, which
- stands for "insert null".
-
- While these are two logically separate attributes (one
- line versus multi-line insert mode, and special treatment
- of untyped spaces) we have seen no terminals whose insert
- mode cannot be described with the single attribute.
-
- Terminfo can describe both terminals which have an insert
- mode, and terminals which send a simple sequence to open a
- blank position on the current line. Give as <STRONG>smir</STRONG> the
- sequence to get into insert mode. Give as <STRONG>rmir</STRONG> the
- sequence to leave insert mode. Now give as <STRONG>ich1</STRONG> any
- sequence needed to be sent just before sending the charac-
- ter to be inserted. Most terminals with a true insert
- mode will not give <STRONG>ich1</STRONG>; terminals which send a sequence
- to open a screen position should give it here.
-
- If your terminal has both, insert mode is usually prefer-
- able to <STRONG>ich1</STRONG>. Technically, you should not give both
- unless the terminal actually requires both to be used in
- combination. Accordingly, some non-curses applications
- get confused if both are present; the symptom is doubled
- characters in an update using insert. This requirement is
- now rare; most <STRONG>ich</STRONG> sequences do not require previous smir,
- and most smir insert modes do not require <STRONG>ich1</STRONG> before each
- character. Therefore, the new <STRONG>curses</STRONG> actually assumes
- this is the case and uses either <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> or <STRONG>ich</STRONG>/<STRONG>ich1</STRONG> as
- appropriate (but not both). If you have to write an entry
- to be used under new curses for a terminal old enough to
- need both, include the <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> sequences in <STRONG>ich1</STRONG>.
-

+ There are two basic kinds of intelligent terminals with respect to
+ insert/delete character which can be described using <EM>terminfo.</EM> The
+ most common insert/delete character operations affect only the charac-
+ ters on the current line and shift characters off the end of the line
+ rigidly. Other terminals, such as the Concept 100 and the Perkin Elmer
+ Owl, make a distinction between typed and untyped blanks on the screen,
+ shifting upon an insert or delete only to an untyped blank on the
+ screen which is either eliminated, or expanded to two untyped blanks.
+
+ You can determine the kind of terminal you have by clearing the screen
+ and then typing text separated by cursor motions. Type "abc def"
+ using local cursor motions (not spaces) between the "abc" and the
+ "def". Then position the cursor before the "abc" and put the terminal
+ in insert mode. If typing characters causes the rest of the line to
+ shift rigidly and characters to fall off the end, then your terminal
+ does not distinguish between blanks and untyped positions. If the
+ "abc" shifts over to the "def" which then move together around the end
+ of the current line and onto the next as you insert, you have the sec-
+ ond type of terminal, and should give the capability <STRONG>in</STRONG>, which stands
+ for "insert null".
+
+ While these are two logically separate attributes (one line versus
+ multi-line insert mode, and special treatment of untyped spaces) we
+ have seen no terminals whose insert mode cannot be described with the
+ single attribute.
+
+ Terminfo can describe both terminals which have an insert mode, and
+ terminals which send a simple sequence to open a blank position on the
+ current line. Give as <STRONG>smir</STRONG> the sequence to get into insert mode. Give
+ as <STRONG>rmir</STRONG> the sequence to leave insert mode. Now give as <STRONG>ich1</STRONG> any
+ sequence needed to be sent just before sending the character to be
+ inserted. Most terminals with a true insert mode will not give <STRONG>ich1</STRONG>;
+ terminals which send a sequence to open a screen position should give
+ it here.
+
+ If your terminal has both, insert mode is usually preferable to <STRONG>ich1</STRONG>.
+ Technically, you should not give both unless the terminal actually
+ requires both to be used in combination. Accordingly, some non-curses
+ applications get confused if both are present; the symptom is doubled
+ characters in an update using insert. This requirement is now rare;
+ most <STRONG>ich</STRONG> sequences do not require previous smir, and most smir insert
+ modes do not require <STRONG>ich1</STRONG> before each character. Therefore, the new
+ <STRONG>curses</STRONG> actually assumes this is the case and uses either <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> or
+ <STRONG>ich</STRONG>/<STRONG>ich1</STRONG> as appropriate (but not both). If you have to write an entry
+ to be used under new curses for a terminal old enough to need both,
+ include the <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> sequences in <STRONG>ich1</STRONG>.
+
+ If post insert padding is needed, give this as a number of milliseconds
+ in <STRONG>ip</STRONG> (a string option). Any other sequence which may need to be sent
+ after an insert of a single character may also be given in <STRONG>ip</STRONG>. If your
+ terminal needs both to be placed into an "insert mode" and a special
+ code to precede each inserted character, then both <STRONG>smir</STRONG>/<STRONG>rmir</STRONG> and <STRONG>ich1</STRONG>
+ can be given, and both will be used. The <STRONG>ich</STRONG> capability, with one
+ parameter, <EM>n</EM>, will repeat the effects of <STRONG>ich1</STRONG> <EM>n</EM> times.
+
+ If padding is necessary between characters typed while not in insert
+ mode, give this as a number of milliseconds padding in <STRONG>rmp</STRONG>.
+
+ It is occasionally necessary to move around while in insert mode to
+ delete characters on the same line (e.g., if there is a tab after the
+ insertion position). If your terminal allows motion while in insert
+ mode you can give the capability <STRONG>mir</STRONG> to speed up inserting in this
+ case. Omitting <STRONG>mir</STRONG> will affect only speed. Some terminals (notably
+ Datamedia's) must not have <STRONG>mir</STRONG> because of the way their insert mode
+ works.
+
+ Finally, you can specify <STRONG>dch1</STRONG> to delete a single character, <STRONG>dch</STRONG> with
+ one parameter, <EM>n</EM>, to delete <EM>n</EM> <EM>characters,</EM> and delete mode by giving
+ <STRONG>smdc</STRONG> and <STRONG>rmdc</STRONG> to enter and exit delete mode (any mode the terminal
+ needs to be placed in for <STRONG>dch1</STRONG> to work).

+ these modes singly may or may not turn off other modes.
+
+ If there is a sequence to set arbitrary combinations of modes, this
+ should be given as <STRONG>sgr</STRONG> (set attributes), taking 9 parameters. Each
+ parameter is either 0 or nonzero, as the corresponding attribute is on

- Most initialization is done with <STRONG>is2</STRONG>. Special terminal
- modes can be set up without duplicating strings by putting
- the common sequences in <STRONG>is2</STRONG> and special cases in <STRONG>is1</STRONG> and
- <STRONG>is3</STRONG>.
-
- A set of sequences that does a harder reset from a totally
- unknown state can be given as <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rf</STRONG> and <STRONG>rs3</STRONG>, analo-
- gous to <STRONG>is1</STRONG> <STRONG>,</STRONG> <STRONG>is2</STRONG> <STRONG>,</STRONG> <STRONG>if</STRONG> and <STRONG>is3</STRONG> respectively. These
- strings are output by the <EM>reset</EM> program, which is used
- when the terminal gets into a wedged state. Commands are
- normally placed in <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG> <STRONG>rs3</STRONG> and <STRONG>rf</STRONG> only if they pro-
- duce annoying effects on the screen and are not necessary
- when logging in. For example, the command to set the
- vt100 into 80-column mode would normally be part of <STRONG>is2</STRONG>,
- but it causes an annoying glitch of the screen and is not
- normally needed since the terminal is usually already in
- 80 column mode.
-
- The <EM>reset</EM> program writes strings including <STRONG>iprog</STRONG>, etc., in
- the same order as the <EM>init</EM> program, using <STRONG>rs1</STRONG>, etc.,
- instead of <STRONG>is1</STRONG>, etc. If any of <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, or <STRONG>rf</STRONG> reset
- capability strings are missing, the <EM>reset</EM> program falls
- back upon the corresponding initialization capability
- string.
-
- If there are commands to set and clear tab stops, they can
- be given as <STRONG>tbc</STRONG> (clear all tab stops) and <STRONG>hts</STRONG> (set a tab
- stop in the current column of every row). If a more com-
- plex sequence is needed to set the tabs than can be
- described by this, the sequence can be placed in <STRONG>is2</STRONG> or
- <STRONG>if</STRONG>.
-
- <STRONG>Delays</STRONG> <STRONG>and</STRONG> <STRONG>Padding</STRONG>
- Many older and slower terminals do not support either
- XON/XOFF or DTR handshaking, including hard copy terminals
- and some very archaic CRTs (including, for example, DEC
- VT100s). These may require padding characters after cer-
- tain cursor motions and screen changes.
-
- If the terminal uses xon/xoff handshaking for flow control
- (that is, it automatically emits ^S back to the host when
- its input buffers are close to full), set <STRONG>xon</STRONG>. This capa-
- bility suppresses the emission of padding. You can also
- set it for memory-mapped console devices effectively that
- do not have a speed limit. Padding information should
- still be included so that routines can make better deci-
- sions about relative costs, but actual pad characters will
- not be transmitted.
-
- If <STRONG>pb</STRONG> (padding baud rate) is given, padding is suppressed
- at baud rates below the value of <STRONG>pb</STRONG>. If the entry has no
- padding baud rate, then whether padding is emitted or not
- is completely controlled by <STRONG>xon</STRONG>.
-
- If the terminal requires other than a null (zero) charac-
- ter as a pad, then this can be given as <STRONG>pad</STRONG>. Only the
- first character of the <STRONG>pad</STRONG> string is used.
-
- <STRONG>Status</STRONG> <STRONG>Lines</STRONG>
- Some terminals have an extra "status line" which is not
- normally used by software (and thus not counted in the
- terminal's <STRONG>lines</STRONG> capability).
-
- The simplest case is a status line which is cursor-
- addressable but not part of the main scrolling region on
- the screen; the Heathkit H19 has a status line of this
- kind, as would a 24-line VT100 with a 23-line scrolling
- region set up on initialization. This situation is indi-
- cated by the <STRONG>hs</STRONG> capability.
-
- Some terminals with status lines need special sequences to
- access the status line. These may be expressed as a
- string with single parameter <STRONG>tsl</STRONG> which takes the cursor to
- a given zero-origin column on the status line. The capa-
- bility <STRONG>fsl</STRONG> must return to the main-screen cursor positions
- before the last <STRONG>tsl</STRONG>. You may need to embed the string
- values of <STRONG>sc</STRONG> (save cursor) and <STRONG>rc</STRONG> (restore cursor) in <STRONG>tsl</STRONG>
- and <STRONG>fsl</STRONG> to accomplish this.
-
- The status line is normally assumed to be the same width
- as the width of the terminal. If this is untrue, you can
- specify it with the numeric capability <STRONG>wsl</STRONG>.
-
- A command to erase or blank the status line may be speci-
- fied as <STRONG>dsl</STRONG>.
-
- The boolean capability <STRONG>eslok</STRONG> specifies that escape
- sequences, tabs, etc., work ordinarily in the status line.
-
- The <STRONG>ncurses</STRONG> implementation does not yet use any of these
- capabilities. They are documented here in case they ever
- become important.
-
- <STRONG>Line</STRONG> <STRONG>Graphics</STRONG>
- Many terminals have alternate character sets useful for
- forms-drawing. Terminfo and <STRONG>curses</STRONG> build in support for
- the drawing characters supported by the VT100, with some
- characters from the AT&amp;T 4410v1 added. This alternate
- character set may be specified by the <STRONG>acsc</STRONG> capability.

- The best way to define a new device's graphics set is to
- add a column to a copy of this table for your terminal,
- giving the character which (when emitted between
- <STRONG>smacs</STRONG>/<STRONG>rmacs</STRONG> switches) will be rendered as the correspond-
- ing graphic. Then read off the VT100/your terminal char-
- acter pairs right to left in sequence; these become the
- ACSC string.
-
- <STRONG>Color</STRONG> <STRONG>Handling</STRONG>
- 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
- background are not independently settable). Up to M
- color-pairs may be set up from 2*M different colors.
- ANSI-compatible terminals are Tektronix-like.
-
- Some basic color capabilities are independent of the color
- method. The numeric capabilities <STRONG>colors</STRONG> and <STRONG>pairs</STRONG> specify
- the maximum numbers of colors and color-pairs that can be
- displayed simultaneously. The <STRONG>op</STRONG> (original pair) string
- resets foreground and background colors to their default
- values for the terminal. The <STRONG>oc</STRONG> string resets all colors
- or color-pairs to their default values for the terminal.
- Some terminals (including many PC terminal emulators)
- erase screen areas with the current background color
- rather than the power-up default background; these should
- have the boolean capability <STRONG>bce</STRONG>.
-
- To change the current foreground or background color on a
- Tektronix-type terminal, use <STRONG>setaf</STRONG> (set ANSI foreground)
- and <STRONG>setab</STRONG> (set ANSI background) or <STRONG>setf</STRONG> (set foreground)
- and <STRONG>setb</STRONG> (set background). These take one parameter, the
- color number. The SVr4 documentation describes only
- <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>; the XPG4 draft says that "If the terminal
- supports ANSI escape sequences to set background and fore-
- ground, they should be coded as <STRONG>setaf</STRONG> and <STRONG>setab</STRONG>, respec-
- tively. If the terminal supports other escape sequences
- to set background and foreground, they should be coded as
- <STRONG>setf</STRONG> and <STRONG>setb</STRONG>, respectively. The <EM>vidputs()</EM> function and
- the refresh functions use <STRONG>setaf</STRONG> and <STRONG>setab</STRONG> if they are
- defined."
-
- The <STRONG>setaf</STRONG>/<STRONG>setab</STRONG> and <STRONG>setf</STRONG>/<STRONG>setb</STRONG> capabilities take a single
- numeric argument each. Argument values 0-7 of <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>
- are portably defined as follows (the middle column is the
- symbolic #define available in the header for the <STRONG>curses</STRONG> or
- <STRONG>ncurses</STRONG> libraries). The terminal hardware is free to map
- these as it likes, but the RGB values indicate normal
- locations in color space.

- magenta <STRONG>COLOR_MAGENTA</STRONG> 5 max,0,max
- cyan <STRONG>COLOR_CYAN</STRONG> 6 0,max,max
- white <STRONG>COLOR_WHITE</STRONG> 7 max,max,max
-
- The argument values of <STRONG>setf</STRONG>/<STRONG>setb</STRONG> historically correspond
- to a different mapping, i.e.,
-
- <STRONG>Color</STRONG> <STRONG>#define</STRONG> <STRONG>Value</STRONG> <STRONG>RGB</STRONG>
- black <STRONG>COLOR_BLACK</STRONG> 0 0, 0, 0
- blue <STRONG>COLOR_BLUE</STRONG> 1 0,0,max
- green <STRONG>COLOR_GREEN</STRONG> 2 0,max,0
- cyan <STRONG>COLOR_CYAN</STRONG> 3 0,max,max
- red <STRONG>COLOR_RED</STRONG> 4 max,0,0
- magenta <STRONG>COLOR_MAGENTA</STRONG> 5 max,0,max
- yellow <STRONG>COLOR_YELLOW</STRONG> 6 max,max,0
- white <STRONG>COLOR_WHITE</STRONG> 7 max,max,max
-
- It is important to not confuse the two sets of color capa-
- bilities; otherwise red/blue will be interchanged on the
- display.
-
- On an HP-like terminal, use <STRONG>scp</STRONG> with a color-pair number
- parameter to set which color pair is current.
-
- On a Tektronix-like terminal, the capability <STRONG>ccc</STRONG> may be
- present to indicate that colors can be modified. If so,
- the <STRONG>initc</STRONG> capability will take a color number (0 to <STRONG>colors</STRONG>
- - 1)and three more parameters which describe the color.
- These three parameters default to being interpreted as RGB
- (Red, Green, Blue) values. If the boolean capability <STRONG>hls</STRONG>
- is present, they are instead as HLS (Hue, Lightness, Satu-
- ration) indices. The ranges are terminal-dependent.
-
- On an HP-like terminal, <STRONG>initp</STRONG> may give a capability for
- changing a color-pair value. It will take seven parame-
- ters; a color-pair number (0 to <STRONG>max_pairs</STRONG> - 1), and two
- triples describing first background and then foreground
- colors. These parameters must be (Red, Green, Blue) or
- (Hue, Lightness, Saturation) depending on <STRONG>hls</STRONG>.
-
- On some color terminals, colors collide with highlights.
- You can register these collisions with the <STRONG>ncv</STRONG> capability.
- This is a bit-mask of attributes not to be used when col-
- ors are enabled. The correspondence with the attributes
- understood by <STRONG>curses</STRONG> is as follows:
-
- <STRONG>Attribute</STRONG> <STRONG>Bit</STRONG> <STRONG>Decimal</STRONG> <STRONG>Set</STRONG> <STRONG>by</STRONG>
- A_STANDOUT 0 1 sgr
- A_UNDERLINE 1 2 sgr
- A_REVERSE 2 4 sgr
- A_BLINK 3 8 sgr
- A_DIM 4 16 sgr
- A_BOLD 5 32 sgr
- A_INVIS 6 64 sgr
- A_PROTECT 7 128 sgr
- A_ALTCHARSET 8 256 sgr
- A_HORIZONTAL 9 512 sgr1
- A_LEFT 10 1024 sgr1
- A_LOW 11 2048 sgr1
- A_RIGHT 12 4096 sgr1
- A_TOP 13 8192 sgr1
- A_VERTICAL 14 16384 sgr1
- A_ITALIC 15 32768 sitm
-
- For example, on many IBM PC consoles, the underline
- attribute collides with the foreground color blue and is
- not available in color mode. These should have an <STRONG>ncv</STRONG>
- capability of 2.
-
- SVr4 curses does nothing with <STRONG>ncv</STRONG>, ncurses recognizes it
- and optimizes the output in favor of colors.
-
- <STRONG>Miscellaneous</STRONG>
- If the terminal requires other than a null (zero) charac-
- ter as a pad, then this can be given as pad. Only the
- first character of the pad string is used. If the termi-
- nal does not have a pad character, specify npc. Note that
- ncurses implements the termcap-compatible <STRONG>PC</STRONG> variable;
- though the application may set this value to something
- other than a null, ncurses will test <STRONG>npc</STRONG> first and use
- napms if the terminal has no pad character.
-
- If the terminal can move up or down half a line, this can
- be indicated with <STRONG>hu</STRONG> (half-line up) and <STRONG>hd</STRONG> (half-line
- down). This is primarily useful for superscripts and sub-
- scripts on hard-copy terminals. If a hard-copy terminal
- can eject to the next page (form feed), give this as <STRONG>ff</STRONG>
- (usually control L).
-
- If there is a command to repeat a given character a given
- number of times (to save time transmitting a large number
- of identical characters) this can be indicated with the
- parameterized string <STRONG>rep</STRONG>. The first parameter is the
- character to be repeated and the second is the number of
- times to repeat it. Thus, tparm(repeat_char, 'x', 10) is
- the same as "xxxxxxxxxx".
-
- If the terminal has a settable command character, such as
- the TEKTRONIX 4025, this can be indicated with <STRONG>cmdch</STRONG>. A
- prototype command character is chosen which is used in all
- capabilities. This character is given in the <STRONG>cmdch</STRONG> capa-
- bility to identify it. The following convention is sup-
- ported on some UNIX systems: The environment is to be
- searched for a <STRONG>CC</STRONG> variable, and if found, all occurrences
- of the prototype character are replaced with the character
- in the environment variable.
-
- Terminal descriptions that do not represent a specific
- kind of known terminal, such as <EM>switch</EM>, <EM>dialup</EM>, <EM>patch</EM>, and
- <EM>network</EM>, should include the <STRONG>gn</STRONG> (generic) capability so
- that programs can complain that they do not know how to
- talk to the terminal. (This capability does not apply to
- <EM>virtual</EM> terminal descriptions for which the escape
- sequences are known.)
-
- If the terminal has a "meta key" which acts as a shift
- key, setting the 8th bit of any character transmitted,
- this fact can be indicated with <STRONG>km</STRONG>. Otherwise, software
- will assume that the 8th bit is parity and it will usually
- be cleared. If strings exist to turn this "meta mode" on
+ and finally output
+ <STRONG>is3</STRONG>.
+
+ Most initialization is done with <STRONG>is2</STRONG>. Special terminal modes can be
+ set up without duplicating strings by putting the common sequences in
+ <STRONG>is2</STRONG> and special cases in <STRONG>is1</STRONG> and <STRONG>is3</STRONG>.
+
+ A set of sequences that does a harder reset from a totally unknown
+ state can be given as <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rf</STRONG> and <STRONG>rs3</STRONG>, analogous to <STRONG>is1</STRONG> <STRONG>,</STRONG> <STRONG>is2</STRONG> <STRONG>,</STRONG> <STRONG>if</STRONG>
+ and <STRONG>is3</STRONG> respectively. These strings are output by <EM>reset</EM> option of
+ <STRONG>tput</STRONG>, or by the <STRONG>reset</STRONG> program (an alias of <STRONG>tset</STRONG>), which is used when
+ the terminal gets into a wedged state. Commands are normally placed in
+ <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG> <STRONG>rs3</STRONG> and <STRONG>rf</STRONG> only if they produce annoying effects on the screen
+ and are not necessary when logging in. For example, the command to set
+ the vt100 into 80-column mode would normally be part of <STRONG>is2</STRONG>, but it
+ causes an annoying glitch of the screen and is not normally needed
+ since the terminal is usually already in 80-column mode.
+
+ The <STRONG>reset</STRONG> program writes strings including <STRONG>iprog</STRONG>, etc., in the same
+ order as the <EM>init</EM> program, using <STRONG>rs1</STRONG>, etc., instead of <STRONG>is1</STRONG>, etc. If
+ any of <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, or <STRONG>rf</STRONG> reset capability strings are missing, the
+ <STRONG>reset</STRONG> program falls back upon the corresponding initialization capabil-
+ ity string.
+
+ If there are commands to set and clear tab stops, they can be given as
+ <STRONG>tbc</STRONG> (clear all tab stops) and <STRONG>hts</STRONG> (set a tab stop in the current column
+ of every row). If a more complex sequence is needed to set the tabs
+ than can be described by this, the sequence can be placed in <STRONG>is2</STRONG> or <STRONG>if</STRONG>.
+
+ The <STRONG>tput</STRONG> <STRONG>reset</STRONG> command uses the same capability strings as the <STRONG>reset</STRONG>
+ command, although the two programs (<STRONG>tput</STRONG> and <STRONG>reset</STRONG>) provide different
+ command-line options.
+
+ In practice, these terminfo capabilities are not often used in initial-
+ ization of tabs (though they are required for the <STRONG>tabs</STRONG> program):
+
+ <STRONG>o</STRONG> Almost all hardware terminals (at least those which supported tabs)
+ initialized those to every <EM>eight</EM> columns:
+
+ The only exception was the AT&amp;T 2300 series, which set tabs to
+ every <EM>five</EM> columns.
+
+ <STRONG>o</STRONG> In particular, developers of the hardware terminals which are com-
+ monly used as models for modern terminal emulators provided docu-
+ mentation demonstrating that <EM>eight</EM> columns were the standard.
+
+ <STRONG>o</STRONG> Because of this, the terminal initialization programs <STRONG>tput</STRONG> and <STRONG>tset</STRONG>
+ use the <STRONG>tbc</STRONG> (<STRONG>clear_all_tabs</STRONG>) and <STRONG>hts</STRONG> (<STRONG>set_tab</STRONG>) capabilities
+ directly only when the <STRONG>it</STRONG> (<STRONG>init_tabs</STRONG>) capability is set to a value
+ other than <EM>eight</EM>.

+ set feature, temporarily switching <EM>modes</EM> and sending characters in
+ the range 0x60 (96) to 0x7e (126) (the <STRONG>acsc</STRONG> <STRONG>Value</STRONG> column in the ta-
+ ble).
+
+ <STRONG>o</STRONG> The AT&amp;T terminal added graphics characters outside that range.
+
+ Some of the characters within the range do not match the VT100;
+ presumably they were used in the AT&amp;T terminal: <EM>board</EM> <EM>of</EM> <EM>squares</EM>
+ replaces the VT100 <EM>newline</EM> symbol, while <EM>lantern</EM> <EM>symbol</EM> replaces
+ the VT100 <EM>vertical</EM> <EM>tab</EM> symbol. The other VT100 symbols for control
+ characters (<EM>horizontal</EM> <EM>tab</EM>, <EM>carriage</EM> <EM>return</EM> and <EM>line-feed</EM>) are not
+ (re)used in curses.
+
+ The best way to define a new device's graphics set is to add a column
+ to a copy of this table for your terminal, giving the character which
+ (when emitted between <STRONG>smacs</STRONG>/<STRONG>rmacs</STRONG> switches) will be rendered as the
+ corresponding graphic. Then read off the VT100/your terminal character
+ pairs right to left in sequence; these become the ACSC string.

+ The curses library functions <STRONG>init_pair</STRONG> and <STRONG>init_color</STRONG> manipulate the
+ <EM>color</EM> <EM>pairs</EM> and <EM>color</EM> <EM>values</EM> discussed in this section (see
+ <STRONG><A HREF="curs_color.3x.html">curs_color(3x)</A></STRONG> for details on these and related functions).
+
+ Most color terminals are either "Tektronix-like" or "HP-like":
+
+ <STRONG>o</STRONG> Tektronix-like terminals have a predefined set of <EM>N</EM> colors (where <EM>N</EM>
+ is usually 8), and can set character-cell foreground and background
+ characters independently, mixing them into <EM>N</EM> * <EM>N</EM> color-pairs.
+
+ <STRONG>o</STRONG> On HP-like terminals, the user must set each color pair up sepa-
+ rately (foreground and background are not independently settable).
+ Up to <EM>M</EM> color-pairs may be set up from 2*<EM>M</EM> different colors. ANSI-
+ compatible terminals are Tektronix-like.
+
+ Some basic color capabilities are independent of the color method. The
+ numeric capabilities <STRONG>colors</STRONG> and <STRONG>pairs</STRONG> specify the maximum numbers of
+ colors and color-pairs that can be displayed simultaneously. The <STRONG>op</STRONG>
+ (original pair) string resets foreground and background colors to their
+ default values for the terminal. The <STRONG>oc</STRONG> string resets all colors or
+ color-pairs to their default values for the terminal. Some terminals
+ (including many PC terminal emulators) erase screen areas with the cur-
+ rent background color rather than the power-up default background;
+ these should have the boolean capability <STRONG>bce</STRONG>.
+
+ While the curses library works with <EM>color</EM> <EM>pairs</EM> (reflecting the inabil-
+ ity of some devices to set foreground and background colors indepen-
+ dently), there are separate capabilities for setting these features:
+
+ <STRONG>o</STRONG> To change the current foreground or background color on a Tek-
+ tronix-type terminal, use <STRONG>setaf</STRONG> (set ANSI foreground) and <STRONG>setab</STRONG>
+ (set ANSI background) or <STRONG>setf</STRONG> (set foreground) and <STRONG>setb</STRONG> (set back-
+ ground). These take one parameter, the color number. The SVr4
+ documentation describes only <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>; the XPG4 draft says that
+ "If the terminal supports ANSI escape sequences to set background
+ and foreground, they should be coded as <STRONG>setaf</STRONG> and <STRONG>setab</STRONG>, respec-
+ tively.
+
+ <STRONG>o</STRONG> If the terminal supports other escape sequences to set background
+ and foreground, they should be coded as <STRONG>setf</STRONG> and <STRONG>setb</STRONG>, respec-
+ tively. The <STRONG>vidputs</STRONG> and the <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG> functions use the <STRONG>setaf</STRONG>
+ and <STRONG>setab</STRONG> capabilities if they are defined.
+
+ The <STRONG>setaf</STRONG>/<STRONG>setab</STRONG> and <STRONG>setf</STRONG>/<STRONG>setb</STRONG> capabilities take a single numeric argu-
+ ment each. Argument values 0-7 of <STRONG>setaf</STRONG>/<STRONG>setab</STRONG> are portably defined as
+ follows (the middle column is the symbolic #define available in the
+ header for the <STRONG>curses</STRONG> or <STRONG>ncurses</STRONG> libraries). The terminal hardware is
+ free to map these as it likes, but the RGB values indicate normal loca-
+ tions in color space.
+
+ <STRONG>Color</STRONG> <STRONG>#define</STRONG> <STRONG>Value</STRONG> <STRONG>RGB</STRONG>

+ cyan <STRONG>COLOR_CYAN</STRONG> 6 0,max,max
+ white <STRONG>COLOR_WHITE</STRONG> 7 max,max,max
+
+ The argument values of <STRONG>setf</STRONG>/<STRONG>setb</STRONG> historically correspond to a different
+ mapping, i.e.,
+
+ <STRONG>Color</STRONG> <STRONG>#define</STRONG> <STRONG>Value</STRONG> <STRONG>RGB</STRONG>
+ black <STRONG>COLOR_BLACK</STRONG> 0 0, 0, 0

+ yellow <STRONG>COLOR_YELLOW</STRONG> 6 max,max,0
+ white <STRONG>COLOR_WHITE</STRONG> 7 max,max,max
+
+ It is important to not confuse the two sets of color capabilities; oth-
+ erwise red/blue will be interchanged on the display.
+
+ On an HP-like terminal, use <STRONG>scp</STRONG> with a color-pair number parameter to
+ set which color pair is current.
+
+ Some terminals allow the <EM>color</EM> <EM>values</EM> to be modified:
+
+ <STRONG>o</STRONG> On a Tektronix-like terminal, the capability <STRONG>ccc</STRONG> may be present to
+ indicate that colors can be modified. If so, the <STRONG>initc</STRONG> capability
+ will take a color number (0 to <STRONG>colors</STRONG> - 1)and three more parameters
+ which describe the color. These three parameters default to being
+ interpreted as RGB (Red, Green, Blue) values. If the boolean capa-
+ bility <STRONG>hls</STRONG> is present, they are instead as HLS (Hue, Lightness,
+ Saturation) indices. The ranges are terminal-dependent.
+
+ <STRONG>o</STRONG> On an HP-like terminal, <STRONG>initp</STRONG> may give a capability for changing a
+ color-pair value. It will take seven parameters; a color-pair num-
+ ber (0 to <STRONG>max_pairs</STRONG> - 1), and two triples describing first back-
+ ground and then foreground colors. These parameters must be (Red,
+ Green, Blue) or (Hue, Lightness, Saturation) depending on <STRONG>hls</STRONG>.
+
+ On some color terminals, colors collide with highlights. You can reg-
+ ister these collisions with the <STRONG>ncv</STRONG> capability. This is a bit-mask of
+ attributes not to be used when colors are enabled. The correspondence
+ with the attributes understood by <STRONG>curses</STRONG> is as follows:
+
+ <STRONG>Attribute</STRONG> <STRONG>Bit</STRONG> <STRONG>Decimal</STRONG> <STRONG>Set</STRONG> <STRONG>by</STRONG>
+ A_STANDOUT 0 1 sgr
+ A_UNDERLINE 1 2 sgr
+ A_REVERSE 2 4 sgr
+ A_BLINK 3 8 sgr
+ A_DIM 4 16 sgr
+ A_BOLD 5 32 sgr
+ A_INVIS 6 64 sgr
+ A_PROTECT 7 128 sgr
+
+ A_ALTCHARSET 8 256 sgr
+ A_HORIZONTAL 9 512 sgr1
+ A_LEFT 10 1024 sgr1
+ A_LOW 11 2048 sgr1

+ A_TOP 13 8192 sgr1
+ A_VERTICAL 14 16384 sgr1
+ A_ITALIC 15 32768 sitm
+
+ For example, on many IBM PC consoles, the underline attribute collides
+ with the foreground color blue and is not available in color mode.
+ These should have an <STRONG>ncv</STRONG> capability of 2.
+
+ SVr4 curses does nothing with <STRONG>ncv</STRONG>, ncurses recognizes it and optimizes
+ the output in favor of colors.

+</PRE><H3><a name="h3-Miscellaneous">Miscellaneous</a></H3><PRE>
+ If the terminal requires other than a null (zero) character as a pad,
+ then this can be given as pad. Only the first character of the pad
+ string is used. If the terminal does not have a pad character, specify
+ npc. Note that ncurses implements the termcap-compatible <STRONG>PC</STRONG> variable;
+ though the application may set this value to something other than a
+ null, ncurses will test <STRONG>npc</STRONG> first and use napms if the terminal has no
+ pad character.
+
+ If the terminal can move up or down half a line, this can be indicated
+ with <STRONG>hu</STRONG> (half-line up) and <STRONG>hd</STRONG> (half-line down). This is primarily use-
+ ful for superscripts and subscripts on hard-copy terminals. If a hard-
+ copy terminal can eject to the next page (form feed), give this as <STRONG>ff</STRONG>
+ (usually control/L).
+
+ If there is a command to repeat a given character a given number of
+ times (to save time transmitting a large number of identical charac-
+ ters) this can be indicated with the parameterized string <STRONG>rep</STRONG>. The
+ first parameter is the character to be repeated and the second is the
+ number of times to repeat it. Thus, tparm(repeat_char, 'x', 10) is the
+ same as "xxxxxxxxxx".
+
+ If the terminal has a settable command character, such as the TEKTRONIX
+ 4025, this can be indicated with <STRONG>cmdch</STRONG>. A prototype command character
+ is chosen which is used in all capabilities. This character is given
+ in the <STRONG>cmdch</STRONG> capability to identify it. The following convention is
+ supported on some UNIX systems: The environment is to be searched for a
+ <STRONG>CC</STRONG> variable, and if found, all occurrences of the prototype character
+ are replaced with the character in the environment variable.
+
+ Terminal descriptions that do not represent a specific kind of known
+ terminal, such as <EM>switch</EM>, <EM>dialup</EM>, <EM>patch</EM>, and <EM>network</EM>, should include
+ the <STRONG>gn</STRONG> (generic) capability so that programs can complain that they do
+ not know how to talk to the terminal. (This capability does not apply
+ to <EM>virtual</EM> terminal descriptions for which the escape sequences are
+ known.)
+
+ If the terminal has a "meta key" which acts as a shift key, setting the
+ 8th bit of any character transmitted, this fact can be indicated with
+ <STRONG>km</STRONG>. Otherwise, software will assume that the 8th bit is parity and it
+ will usually be cleared. If strings exist to turn this "meta mode" on
and off, they can be given as <STRONG>smm</STRONG> and <STRONG>rmm</STRONG>.
- If the terminal has more lines of memory than will fit on
- the screen at once, the number of lines of memory can be
- indicated with <STRONG>lm</STRONG>. A value of <STRONG>lm</STRONG>#0 indicates that the
- number of lines is not fixed, but that there is still more
- memory than fits on the screen.
-
- If the terminal is one of those supported by the UNIX vir-
- tual terminal protocol, the terminal number can be given
- as <STRONG>vt</STRONG>.
-
- Media copy strings which control an auxiliary printer con-
- nected to the terminal can be given as <STRONG>mc0</STRONG>: print the con-
- tents of the screen, <STRONG>mc4</STRONG>: turn off the printer, and <STRONG>mc5</STRONG>:
- turn on the printer. When the printer is on, all text
- sent to the terminal will be sent to the printer. It is
- undefined whether the text is also displayed on the termi-
- nal screen when the printer is on. A variation <STRONG>mc5p</STRONG> takes
- one parameter, and leaves the printer on for as many char-
- acters as the value of the parameter, then turns the
- printer off. The parameter should not exceed 255. All
- text, including <STRONG>mc4</STRONG>, is transparently passed to the
- printer while an <STRONG>mc5p</STRONG> is in effect.
-
- <STRONG>Glitches</STRONG> <STRONG>and</STRONG> <STRONG>Braindamage</STRONG>
- Hazeltine terminals, which do not allow "~" characters to

- wrap, such as the Concept and vt100, should indicate <STRONG>xenl</STRONG>.
-
- If <STRONG>el</STRONG> is required to get rid of standout (instead of
- merely writing normal text on top of it), <STRONG>xhp</STRONG> should be
- given.
-
- Teleray terminals, where tabs turn all characters moved
- over to blanks, should indicate <STRONG>xt</STRONG> (destructive tabs).
- Note: the variable indicating this is now
- "dest_tabs_magic_smso"; in older versions, it was tel-
- eray_glitch. This glitch is also taken to mean that it is
- not possible to position the cursor on top of a "magic
- cookie", that to erase standout mode it is instead neces-
- sary to use delete and insert line. The ncurses implemen-
- tation ignores this glitch.
-
- The Beehive Superbee, which is unable to correctly trans-

-
- <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
+ If the terminal has more lines of memory than will fit on the screen at

+
+ If the terminal is one of those supported by the UNIX virtual terminal

+</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. Unfor-
+ tunately, the termcap translations are much more strictly limited (to
+ 1023 bytes), thus termcap translations of long terminfo entries can
+ cause problems.
+
+ 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 where in
+ the termcap file the terminal type that <STRONG>tgetent</STRONG> is searching for is,
+ several bad things can happen.
+
+ Some termcap libraries print a warning message or exit if they find an
+ entry that's longer than 1023 bytes; others do not; others truncate the
+ entries to 1023 bytes. Some application programs allocate more than
+ the recommended 1K for the termcap entry; others do not.
+
+ Each termcap entry has two important sizes associated with it: before
+ "tc" expansion, and after "tc" expansion. "tc" is the capability that
+ tacks on another termcap entry to the end of the current one, to add on
+ its capabilities. If a termcap entry does not use the "tc" capability,
+ then of course the two lengths are the same.
+
+ The "before tc expansion" length is the most important one, because it
+ affects more than just users of that particular 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
+ libraries strip off the final newline, too (GNU termcap does not). Now
+ suppose:
+
+ <STRONG>o</STRONG> a termcap entry before expansion is more than 1023 bytes long,
- 2621-nl, smkx@, rmkx@, use=2621,
+ <STRONG>o</STRONG> and the application has only allocated a 1k buffer,
- 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.
-

- Long terminfo entries are unlikely to be a problem; to

-
- <STRONG>o</STRONG> a termcap entry before expansion is more than 1023
- bytes long,
+ <STRONG>o</STRONG> and the termcap library (like the one in BSD/OS 1.1 and GNU) reads

+
+ <STRONG>o</STRONG> and <STRONG>tgetent</STRONG> is searching for a terminal type that either is the
+ long entry, appears in the termcap file after the long entry, or
+ does not appear in the file at all (so that <STRONG>tgetent</STRONG> has to search

- <STRONG>o</STRONG> and the application has only allocated a 1k buffer,

+ cally. The results are almost as undesirable with a termcap library,
+ like SunOS 4.1.3 and Ultrix 4.4, that prints warning messages when it
+ reads an overly long termcap entry. If a termcap library truncates
+ long entries, like OSF/1 3.0, it is immune to dying here but will
+ return incorrect data for the terminal.

-
- When in -C (translate to termcap) mode, the <STRONG>ncurses</STRONG> imple-

-
- <STRONG>Binary</STRONG> <STRONG>Compatibility</STRONG>
- It is not wise to count on portability of binary terminfo
- entries between commercial UNIX versions. The problem is
- that there are at least two versions of terminfo (under
- HP-UX and AIX) which diverged from System V terminfo after
- SVr1, and have added extension capabilities to the string
- table that (in the binary format) collide with System V
- and XSI Curses extensions.

- Different commercial ports of terminfo and curses support

-
- <STRONG>SVR4,</STRONG> <STRONG>Solaris,</STRONG> <STRONG>ncurses</STRONG> -- These support all SVr4 capabili-
- ties.
-
- <STRONG>SGI</STRONG> -- Supports the SVr4 set, adds one undocumented
- extended string capability (<STRONG>set_pglen</STRONG>).
-
- <STRONG>SVr1,</STRONG> <STRONG>Ultrix</STRONG> -- These support a restricted subset of ter-
- minfo capabilities. The booleans end with <STRONG>xon_xoff</STRONG>; the
- numerics with <STRONG>width_status_line</STRONG>; and the strings with
- <STRONG>prtr_non</STRONG>.
-
- <STRONG>HP/UX</STRONG> -- Supports the SVr1 subset, plus the SVr[234]
- numerics <STRONG>num_labels</STRONG>, <STRONG>label_height</STRONG>, <STRONG>label_width</STRONG>, plus func-
- tion keys 11 through 63, plus <STRONG>plab_norm</STRONG>, <STRONG>label_on</STRONG>, and
- <STRONG>label_off</STRONG>, plus some incompatible extensions in the string
- table.
-
- <STRONG>AIX</STRONG> -- Supports the SVr1 subset, plus function keys 11
- through 63, plus a number of incompatible string table
- extensions.
-
- <STRONG>OSF</STRONG> -- Supports both the SVr4 set and the AIX extensions.
+ When in -C (translate to termcap) mode, the <STRONG>ncurses</STRONG> implementation of
+ <STRONG><A HREF="tic.1m.html">tic(1m)</A></STRONG> issues warning messages when the pre-tc length of a termcap
+ translation is too long. The -c (check) option also checks resolved
+ (after tc expansion) lengths.

+ It is not wise to count on portability of binary terminfo entries
+ between commercial UNIX versions. The problem is that there are at
+ least two versions of terminfo (under HP-UX and AIX) which diverged
+ from System V terminfo after SVr1, and have added extension capabili-
+ ties to the string table that (in the binary format) collide with Sys-
+ tem V and XSI Curses extensions.

+ SVr4/XPG4 do not specify whether <STRONG>msgr</STRONG> licenses movement while in an
+ alternate-character-set mode (such modes may, among other things, map
+ CR and NL to characters that do not trigger local motions). The
+ <STRONG>ncurses</STRONG> implementation ignores <STRONG>msgr</STRONG> in <STRONG>ALTCHARSET</STRONG> mode. This raises
+ the possibility that an XPG4 implementation making the opposite inter-
+ pretation may need terminfo entries made for <STRONG>ncurses</STRONG> to have <STRONG>msgr</STRONG>
+ turned off.
