63 <EM>Terminfo</EM> is a database describing terminals, used by screen-oriented
64 programs such as <STRONG>nvi(1)</STRONG>, <STRONG>lynx(1)</STRONG>, <STRONG>mutt(1)</STRONG>, and other curses
65 applications, using high-level calls to libraries such as <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>.
66 It is also used via low-level calls by non-curses applications which
67 may be screen-oriented (such as <STRONG><A HREF="clear.1.html">clear(1)</A></STRONG>) or non-screen (such as
68 <STRONG><A HREF="tabs.1.html">tabs(1)</A></STRONG>).
70 <EM>Terminfo</EM> describes terminals by giving a set of capabilities which they
71 have, by specifying how to perform screen operations, and by specifying
72 padding requirements and initialization sequences.
74 This manual describes <EM>ncurses</EM> version 6.4 (patch 20240224).
77 </PRE><H3><a name="h3-terminfo-Entry-Syntax"><EM>terminfo</EM> Entry Syntax</a></H3><PRE>
78 Entries in <EM>terminfo</EM> consist of a sequence of fields:
80 <STRONG>o</STRONG> Each field ends with a comma "," (embedded commas may be escaped
81 with a backslash or written as "\054").
83 <STRONG>o</STRONG> White space between fields is ignored.
85 <STRONG>o</STRONG> The first field in a <EM>terminfo</EM> entry begins in the first column.
87 <STRONG>o</STRONG> Newlines and leading whitespace (spaces or tabs) may be used for
88 formatting entries for readability. These are removed from parsed
91 The <STRONG>infocmp</STRONG> <STRONG>-f</STRONG> and <STRONG>-W</STRONG> options rely on this to format if-then-else
92 expressions, or to enforce maximum line-width. The resulting
93 formatted terminal description can be read by <STRONG>tic</STRONG>.
95 <STRONG>o</STRONG> The first field for each terminal gives the names which are known
96 for the terminal, separated by "|" characters.
98 The first name given is the most common abbreviation for the
99 terminal (its primary name), the last name given should be a long
100 name fully identifying the terminal (see <STRONG><A HREF="curs_termattrs.3x.html">longname(3x)</A></STRONG>), and all
101 others are treated as synonyms (aliases) for the primary terminal
104 X/Open Curses advises that all names but the last should be in
105 lower case and contain no blanks; the last name may well contain
106 upper case and blanks for readability.
108 This implementation is not so strict; it allows mixed case in the
109 primary name and aliases. If the last name has no embedded blanks,
110 it allows that to be both an alias and a verbose name (but will
111 warn about this ambiguity).
113 <STRONG>o</STRONG> Lines beginning with a "#" in the first column are treated as
116 While comment lines are valid at any point, the output of <STRONG>captoinfo</STRONG>
117 and <STRONG>infotocap</STRONG> (aliases for <STRONG>tic</STRONG>) will move comments so they occur
118 only between entries.
120 Terminal names (except for the last, verbose entry) should be chosen
121 using the following conventions. The particular piece of hardware
122 making up the terminal should have a root name, thus "hp2621". This
123 name should not contain hyphens. Modes that the hardware can be in, or
124 user preferences, should be indicated by appending a hyphen and a mode
125 suffix. Thus, a vt100 in 132-column mode would be vt100-w. The
126 following suffixes should be used where possible:
128 <STRONG>Suffix</STRONG> <STRONG>Example</STRONG> <STRONG>Meaning</STRONG>
129 ------------------------------------------------------------------------
130 -<EM>nn</EM> aaa-60 Number of lines on the screen
131 -<EM>n</EM>p c100-4p Number of pages of memory
132 -am vt100-am With automargins (usually the default)
133 -m ansi-m Mono mode; suppress color
134 -mc wy30-mc Magic cookie; spaces when highlighting
135 -na c100-na No arrow keys (leave them in local)
136 -nam vt100-nam Without automatic margins
137 -nl hp2621-nl No status line
138 -ns hp2626-ns No status line
139 -rv c100-rv Reverse video
140 -s vt100-s Enable status line
141 -vb wy370-vb Use visible bell instead of beep
142 -w vt100-w Wide mode (> 80 columns, usually 132)
144 For more on terminal naming conventions, see the <STRONG><A HREF="term.7.html">term(7)</A></STRONG> manual page.
147 </PRE><H3><a name="h3-terminfo-Capabilities-Syntax"><EM>terminfo</EM> Capabilities Syntax</a></H3><PRE>
148 The terminfo entry consists of several <EM>capabilities</EM>, i.e., features
149 that the terminal has, or methods for exercising the terminal's
152 After the first field (giving the name(s) of the terminal entry), there
153 should be one or more <EM>capability</EM> fields. These are Boolean, numeric or
154 string names with corresponding values:
156 <STRONG>o</STRONG> Boolean capabilities are true when present, false when absent.
157 There is no explicit value for Boolean capabilities.
159 <STRONG>o</STRONG> Numeric capabilities have a "#" following the name, then an
160 unsigned decimal integer value.
162 <STRONG>o</STRONG> String capabilities have a "=" following the name, then an string
163 of characters making up the capability value.
165 String capabilities can be split into multiple lines, just as the
166 fields comprising a terminal entry can be split into multiple
167 lines. While blanks between fields are ignored, blanks embedded
168 within a string value are retained, except for leading blanks on a
171 Any capability can be <EM>canceled</EM>, i.e., suppressed from the terminal
172 entry, by following its name with "@" rather than a capability value.
175 </PRE><H3><a name="h3-Similar-Terminals">Similar Terminals</a></H3><PRE>
176 If there are two very similar terminals, one (the variant) can be
177 defined as being just like the other (the base) with certain
178 exceptions. In the definition of the variant, the string capability
179 <STRONG>use</STRONG> can be given with the name of the base terminal:
181 <STRONG>o</STRONG> The capabilities given before <STRONG>use</STRONG> override those in the base type
182 named by <STRONG>use</STRONG>.
184 <STRONG>o</STRONG> If there are multiple <STRONG>use</STRONG> capabilities, they are merged in reverse
185 order. That is, the rightmost <STRONG>use</STRONG> reference is processed first,
186 then the one to its left, and so forth.
188 <STRONG>o</STRONG> Capabilities given explicitly in the entry override those brought
189 in by <STRONG>use</STRONG> references.
191 A capability can be canceled by placing <STRONG>xx@</STRONG> to the left of the use
192 reference that imports it, where <EM>xx</EM> is the capability. For example,
195 2621-nl, smkx@, rmkx@, use=2621,
197 defines a 2621-nl that does not have the <STRONG>smkx</STRONG> or <STRONG>rmkx</STRONG> capabilities, and
198 hence does not turn on the function key labels when in visual mode.
199 This is useful for different modes for a terminal, or for different
202 An entry included via <STRONG>use</STRONG> can contain canceled capabilities, which have
203 the same effect as if those cancels were inline in the using terminal
207 </PRE><H3><a name="h3-Predefined-Capabilities">Predefined Capabilities</a></H3><PRE>
208 The following is a complete table of the capabilities included in a
209 terminfo description block and available to terminfo-using code. In
210 each line of the table,
212 <STRONG>o</STRONG> The <STRONG>variable</STRONG> is the name by which the programmer (at the terminfo
213 level) accesses the capability.
215 <STRONG>o</STRONG> The <STRONG>capname</STRONG> (<EM>Cap-name</EM>) is the short name used in the text of the
216 database, and is used by a person updating the database.
218 Whenever possible, capnames are chosen to be the same as or similar
219 to the ANSI X3.64-1979 standard (now superseded by ECMA-48, which
220 uses identical or very similar names). Semantics are also intended
221 to match those of the specification.
223 Capability names have no hard length limit, but an informal limit
224 of 5 characters has been adopted to keep them short and to allow
225 the tabs in the source file <STRONG>Caps</STRONG> to line up nicely.
227 <STRONG>o</STRONG> The <STRONG>termcap</STRONG> (<EM>Tcap</EM>) code is the old capability name (some
228 capabilities are new, and have names which termcap did not
231 <STRONG>o</STRONG> Finally, the <STRONG>description</STRONG> field attempts to convey the semantics of
234 You may find some codes in the description field:
236 (P) indicates that padding may be specified
238 #[1-9] in the description field indicates that the string is passed
239 through <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG> with parameters as given (#<EM>i</EM>).
241 If no parameters are listed in the description, passing the
242 string through <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG> may give unexpected results, e.g., if
243 it contains percent (%%) signs.
245 (P*) indicates that padding may vary in proportion to the number of
248 (#<EM>i</EM>) indicates the <EM>i</EM>th parameter.

928 The preceding section listed the <EM>predefined</EM> capabilities. They deal
929 with some special features for terminals no longer (or possibly never)
930 produced. Occasionally there are special features of newer terminals
931 which are awkward or impossible to represent by reusing the predefined
934 <EM>ncurses</EM> addresses this limitation by allowing user-defined
935 capabilities. The <STRONG>tic</STRONG> and <STRONG>infocmp</STRONG> programs provide the <STRONG>-x</STRONG> option for
936 this purpose. When <STRONG>-x</STRONG> is set, <STRONG>tic</STRONG> treats unknown capabilities as user-
937 defined. That is, if <STRONG>tic</STRONG> encounters a capability name which it does
938 not recognize, it infers its type (Boolean, number or string) from the
939 syntax and makes an extended table entry for that capability. The
940 <STRONG><A HREF="curs_extend.3x.html">use_extended_names(3x)</A></STRONG> function makes this information conditionally
941 available to applications. The <EM>ncurses</EM> library provides the data
942 leaving most of the behavior to applications:
944 <STRONG>o</STRONG> User-defined capability strings whose name begins with "k" are
945 treated as function keys.
947 <STRONG>o</STRONG> The types (Boolean, number, string) determined by <STRONG>tic</STRONG> can be
948 inferred by successful calls on <STRONG>tigetflag</STRONG>, etc.
950 <STRONG>o</STRONG> If the capability name happens to be two characters, the capability
951 is also available through the termcap interface.
953 While termcap is said to be extensible because it does not use a
954 predefined set of capabilities, in practice it has been limited to the
955 capabilities defined by terminfo implementations. As a rule, user-
956 defined capabilities intended for use by termcap applications should be
957 limited to Booleans and numbers to avoid running past the 1023 byte
958 limit assumed by termcap implementations and their applications. In
959 particular, providing extended sets of function keys (past the 60
960 numbered keys and the handful of special named keys) is best done using
961 the longer names available using terminfo.
963 The <EM>ncurses</EM> library uses a few of these user-defined capabilities, as
964 described in <STRONG><A HREF="user_caps.5.html">user_caps(5)</A></STRONG>. Other user-defined capabilities (including
965 function keys) are described in the terminal database, in the section
966 on <EM>NCURSES</EM> <EM>USER-DEFINABLE</EM> <EM>CAPABILITIES</EM>

1005 Entries may continue onto multiple lines by placing white space at the
1006 beginning of each line except the first. Comments may be included on
1007 lines beginning with "#". Capabilities in <EM>terminfo</EM> are of three types:
1009 <STRONG>o</STRONG> Boolean capabilities which indicate that the terminal has some
1012 <STRONG>o</STRONG> numeric capabilities giving the size of the terminal or the size of
1013 particular delays, and
1015 <STRONG>o</STRONG> string capabilities, which give a sequence which can be used to
1016 perform particular terminal operations.
1019 </PRE><H3><a name="h3-Types-of-Capabilities">Types of Capabilities</a></H3><PRE>
1020 All capabilities have names. For instance, the fact that ANSI-standard
1021 terminals have <EM>automatic</EM> <EM>margins</EM> (i.e., an automatic return and line-
1022 feed when the end of a line is reached) is indicated by the capability
1023 <STRONG>am</STRONG>. Hence the description of ansi includes <STRONG>am</STRONG>. Numeric capabilities
1024 are followed by the character "#" and then a positive value. Thus
1025 <STRONG>cols</STRONG>, which indicates the number of columns the terminal has, gives the
1026 value "80" for ansi. Values for numeric capabilities may be specified
1027 in decimal, octal, or hexadecimal, using the C programming language
1028 conventions (e.g., 255, 0377 and 0xff or 0xFF).
1030 Finally, string valued capabilities, such as <STRONG>el</STRONG> (clear to end of line
1031 sequence) are given by the two-character code, an "=", and then a
1032 string ending at the next following ",".
1034 A number of escape sequences are provided in the string valued
1035 capabilities for easy encoding of characters there:
1037 <STRONG>o</STRONG> Both <STRONG>\E</STRONG> and <STRONG>\e</STRONG> map to an ESCAPE character,
1039 <STRONG>o</STRONG> <STRONG>^</STRONG><STRONG><EM>x</EM></STRONG> maps to a control-<EM>x</EM> for any appropriate <EM>x</EM>, and
1041 <STRONG>o</STRONG> the sequences
1043 <STRONG>\n</STRONG>, <STRONG>\l</STRONG>, <STRONG>\r</STRONG>, <STRONG>\t</STRONG>, <STRONG>\b</STRONG>, <STRONG>\f</STRONG>, and <STRONG>\s</STRONG>
1047 <EM>newline</EM>, <EM>line-feed</EM>, <EM>return</EM>, <EM>tab</EM>, <EM>backspace</EM>, <EM>form-feed</EM>, and <EM>space</EM>,
1051 X/Open Curses does not say what "appropriate <EM>x</EM>" might be. In practice,
1052 that is a printable ASCII graphic character. The special case "^?" is
1053 interpreted as DEL (127). In all other cases, the character value is
1054 AND'd with 0x1f, mapping to ASCII control codes in the range 0 through
1057 Other escapes include
1059 <STRONG>o</STRONG> <STRONG>\^</STRONG> for <STRONG>^</STRONG>,
1061 <STRONG>o</STRONG> <STRONG>\\</STRONG> for <STRONG>\</STRONG>,
1063 <STRONG>o</STRONG> <STRONG>\</STRONG>, for comma,
1065 <STRONG>o</STRONG> <STRONG>\:</STRONG> for <STRONG>:</STRONG>,
1067 <STRONG>o</STRONG> and <STRONG>\0</STRONG> for null.
1069 <STRONG>\0</STRONG> will produce \200, which does not terminate a string but behaves
1070 as a null character on most terminals, providing CS7 is specified.
1071 See <STRONG>stty(1)</STRONG>.
1073 The reason for this quirk is to maintain binary compatibility of
1074 the compiled terminfo files with other implementations, e.g., the
1075 SVr4 systems, which document this. Compiled terminfo files use
1076 null-terminated strings, with no lengths. Modifying this would
1077 require a new binary format, which would not work with other
1080 Finally, characters may be given as three octal digits after a <STRONG>\</STRONG>.
1082 A delay in milliseconds may appear anywhere in a string capability,
1083 enclosed in $<..> brackets, as in <STRONG>el</STRONG>=\EK$<5>, and padding characters
1084 are supplied by <STRONG><A HREF="curs_terminfo.3x.html">tputs(3x)</A></STRONG> to provide this delay.
1086 <STRONG>o</STRONG> The delay must be a number with at most one decimal place of
1087 precision; it may be followed by suffixes "*" or "/" or both.
1089 <STRONG>o</STRONG> A "*" indicates that the padding required is proportional to the
1090 number of lines affected by the operation, and the amount given is
1091 the per-affected-unit padding required. (In the case of insert
1092 character, the factor is still the number of <EM>lines</EM> affected.)
1094 Normally, padding is advisory if the device has the <STRONG>xon</STRONG> capability;
1095 it is used for cost computation but does not trigger delays.
1097 <STRONG>o</STRONG> A "/" suffix indicates that the padding is mandatory and forces a
1098 delay of the given number of milliseconds even on devices for which
1099 <STRONG>xon</STRONG> is present to indicate flow control.
1101 Sometimes individual capabilities must be commented out. To do this,
1102 put a period before the capability name. For example, see the second
1103 <STRONG>ind</STRONG> in the example above.
1106 </PRE><H3><a name="h3-Fetching-Compiled-Descriptions">Fetching Compiled Descriptions</a></H3><PRE>
1107 Terminal descriptions in <EM>ncurses</EM> are stored in terminal databases.
1108 These databases, which are found by their pathname, may be configured
1109 either as directory trees or hashed databases (see <STRONG><A HREF="term.5.html">term(5)</A></STRONG>),
1111 The library uses a compiled-in list of pathnames, which can be
1112 overridden by environment variables. Before starting to search,
1113 <EM>ncurses</EM> checks the search list, eliminating duplicates and pathnames
1114 where no terminal database is found. The <EM>ncurses</EM> library reads the
1115 first description which passes its consistency checks.
1117 <STRONG>o</STRONG> The environment variable <STRONG>TERMINFO</STRONG> is checked first, for a terminal
1118 database containing the terminal description.
1120 <STRONG>o</STRONG> Next, <EM>ncurses</EM> looks in <EM>$HOME/.terminfo</EM> for a compiled description.
1122 This is an optional feature which may be omitted entirely from the
1123 library, or limited to prevent accidental use by privileged
1126 <STRONG>o</STRONG> Next, if the environment variable <EM>TERMINFO</EM><STRONG>_</STRONG><EM>DIRS</EM> is set, <EM>ncurses</EM>
1127 interprets the contents of that variable as a list of colon-
1128 separated pathnames of terminal databases to be searched.
1130 An empty pathname (i.e., if the variable begins or ends with a
1131 colon, or contains adjacent colons) is interpreted as the system
1132 location <EM>/usr/share/terminfo</EM>.
1134 <STRONG>o</STRONG> Finally, <EM>ncurses</EM> searches these compiled-in locations:
1136 <STRONG>o</STRONG> a list of directories (/usr/share/terminfo), and
1138 <STRONG>o</STRONG> the system terminfo directory, <EM>/usr/share/terminfo</EM>
1140 The <STRONG>TERMINFO</STRONG> variable can contain a terminal description instead of the
1141 pathname of a terminal database. If this variable begins with "hex:"
1142 or "b64:" then <EM>ncurses</EM> reads a terminal description from hexadecimal-
1143 or base64-encoded data, and if that description matches the name
1144 sought, will use that. This encoded data can be set using the "-Q"
1145 option of <STRONG>tic</STRONG> or <STRONG>infocmp</STRONG>.
1147 The preceding addresses the usual configuration of <EM>ncurses</EM>, which uses
1148 terminal descriptions prepared in <EM>terminfo</EM> format. While <EM>termcap</EM> is
1149 less expressive, <EM>ncurses</EM> can also be configured to read <EM>termcap</EM>
1150 descriptions. In that configuration, it checks the <EM>TERMCAP</EM> and
1151 <EM>TERMPATH</EM> variables (for content and search path, respectively) after
1152 the system terminal database.
1155 </PRE><H3><a name="h3-Preparing-Descriptions">Preparing Descriptions</a></H3><PRE>
1156 We now outline how to prepare descriptions of terminals. The most
1157 effective way to prepare a terminal description is by imitating the
1158 description of a similar terminal in <EM>terminfo</EM> and to build up a
1159 description gradually, using partial descriptions with <EM>vi</EM> or some other
1160 screen-oriented program to check that they are correct. Be aware that
1161 a very unusual terminal may expose deficiencies in the ability of the
1162 <EM>terminfo</EM> file to describe it or bugs in the screen-handling code of the
1165 To get the padding for insert line right (if the terminal manufacturer
1166 did not document it) a severe test is to edit a large file at 9600
1167 baud, delete 16 or so lines from the middle of the screen, then hit the
1168 "u" key several times quickly. If the terminal messes up, more padding
1169 is usually needed. A similar test can be used for insert character.
1172 </PRE><H3><a name="h3-Basic-Capabilities">Basic Capabilities</a></H3><PRE>
1173 The number of columns on each line for the terminal is given by the
1174 <STRONG>cols</STRONG> numeric capability. If the terminal is a CRT, then the number of
1175 lines on the screen is given by the <STRONG>lines</STRONG> capability. If the terminal
1176 wraps around to the beginning of the next line when it reaches the
1177 right margin, then it should have the <STRONG>am</STRONG> capability. If the terminal
1178 can clear its screen, leaving the cursor in the home position, then
1179 this is given by the <STRONG>clear</STRONG> string capability. If the terminal
1180 overstrikes (rather than clearing a position when a character is struck
1181 over) then it should have the <STRONG>os</STRONG> capability. If the terminal is a
1182 printing terminal, with no soft copy unit, give it both <STRONG>hc</STRONG> and <STRONG>os</STRONG>. (<STRONG>os</STRONG>
1183 applies to storage scope terminals, such as TEKTRONIX 4010 series, as
1184 well as hard copy and APL terminals.) If there is a code to move the
1185 cursor to the left edge of the current row, give this as <STRONG>cr</STRONG>. (Normally
1186 this will be carriage return, control/M.) If there is a code to
1187 produce an audible signal (bell, beep, etc) give this as <STRONG>bel</STRONG>.
1189 If there is a code to move the cursor one position to the left (such as
1190 backspace) that capability should be given as <STRONG>cub1</STRONG>. Similarly, codes
1191 to move to the right, up, and down should be given as <STRONG>cuf1</STRONG>, <STRONG>cuu1</STRONG>, and
1192 <STRONG>cud1</STRONG>. These local cursor motions should not alter the text they pass
1193 over, for example, you would not normally use "<STRONG>cuf1</STRONG>= " because the
1194 space would erase the character moved over.
1196 A very important point here is that the local cursor motions encoded in
1197 <EM>terminfo</EM> are undefined at the left and top edges of a CRT terminal.
1198 Programs should never attempt to backspace around the left edge, unless
1199 <STRONG>bw</STRONG> is given, and never attempt to go up locally off the top. In order
1200 to scroll text up, a program will go to the bottom left corner of the
1201 screen and send the <STRONG>ind</STRONG> (index) string.
1203 To scroll text down, a program goes to the top left corner of the
1204 screen and sends the <STRONG>ri</STRONG> (reverse index) string. The strings <STRONG>ind</STRONG> and <STRONG>ri</STRONG>
1205 are undefined when not on their respective corners of the screen.
1207 Parameterized versions of the scrolling sequences are <STRONG>indn</STRONG> and <STRONG>rin</STRONG>
1208 which have the same semantics as <STRONG>ind</STRONG> and <STRONG>ri</STRONG> except that they take one
1209 parameter, and scroll that many lines. They are also undefined except
1210 at the appropriate edge of the screen.
1212 The <STRONG>am</STRONG> capability tells whether the cursor sticks at the right edge of
1213 the screen when text is output, but this does not necessarily apply to
1214 a <STRONG>cuf1</STRONG> from the last column. The only local motion which is defined
1215 from the left edge is if <STRONG>bw</STRONG> is given, then a <STRONG>cub1</STRONG> from the left edge
1216 will move to the right edge of the previous row. If <STRONG>bw</STRONG> is not given,
1217 the effect is undefined. This is useful for drawing a box around the
1218 edge of the screen, for example. If the terminal has switch selectable
1219 automatic margins, the <EM>terminfo</EM> file usually assumes that this is on;
1220 i.e., <STRONG>am</STRONG>. If the terminal has a command which moves to the first
1221 column of the next line, that command can be given as <STRONG>nel</STRONG> (newline).
1222 It does not matter if the command clears the remainder of the current
1223 line, so if the terminal has no <STRONG>cr</STRONG> and <STRONG>lf</STRONG> it may still be possible to
1224 craft a working <STRONG>nel</STRONG> out of one or both of them.
1226 These capabilities suffice to describe hard-copy and "glass-tty"
1227 terminals. Thus the model 33 teletype is described as
1229 33|tty33|tty|model 33 teletype,
1230 bel=^G, cols#72, cr=^M, cud1=^J, hc, ind=^J, os,
1232 while the Lear Siegler ADM-3 is described as
1235 am, bel=^G, clear=^Z, cols#80, cr=^M, cub1=^H, cud1=^J,
1239 </PRE><H3><a name="h3-Parameterized-Strings">Parameterized Strings</a></H3><PRE>
1240 Cursor addressing and other strings requiring parameters in the
1241 terminal are described by a parameterized string capability, with
1242 <EM>printf</EM>-like escapes such as <EM>%x</EM> in it. For example, to address the
1243 cursor, the <STRONG>cup</STRONG> capability is given, using two parameters: the row and
1244 column to address to. (Rows and columns are numbered from zero and
1245 refer to the physical screen visible to the user, not to any unseen
1246 memory.) If the terminal has memory relative cursor addressing, that
1247 can be indicated by <STRONG>mrcup</STRONG>.
1249 The parameter mechanism uses a stack and special <STRONG>%</STRONG> codes to manipulate
1250 it. Typically a sequence will push one of the parameters onto the
1251 stack and then print it in some format. Print (e.g., "%d") is a
1252 special case. Other operations, including "%t" pop their operand from
1253 the stack. It is noted that more complex operations are often
1254 necessary, e.g., in the <STRONG>sgr</STRONG> string.
1256 The <STRONG>%</STRONG> encodings have the following meanings:
1258 <STRONG>%%</STRONG> outputs "%"
1260 <STRONG>%</STRONG><EM>[[</EM>:<EM>]flags][width[.precision]][</EM><STRONG>doxXs</STRONG><EM>]</EM>
1261 as in <STRONG>printf(3)</STRONG>, flags are <EM>[-+#]</EM> and <EM>space</EM>. Use a ":" to allow
1262 the next character to be a "-" flag, avoiding interpreting "%-" as
1265 <STRONG>%c</STRONG> print <EM>pop()</EM> like %c in <STRONG>printf</STRONG>
1267 <STRONG>%s</STRONG> print <EM>pop()</EM> like %s in <STRONG>printf</STRONG>
1269 <STRONG>%p</STRONG><EM>[1-9]</EM>
1270 push <EM>i</EM>'th parameter
1272 <STRONG>%P</STRONG><EM>[a-z]</EM>
1273 set dynamic variable <EM>[a-z]</EM> to <EM>pop()</EM>
1275 <STRONG>%g</STRONG><EM>[a-z]</EM>
1276 get dynamic variable <EM>[a-z]</EM> and push it
1278 <STRONG>%P</STRONG><EM>[A-Z]</EM>
1279 set static variable <EM>[a-z]</EM> to <EM>pop()</EM>
1281 <STRONG>%g</STRONG><EM>[A-Z]</EM>
1282 get static variable <EM>[a-z]</EM> and push it
1284 The terms "static" and "dynamic" are misleading. Historically,
1285 these are simply two different sets of variables, whose values are
1286 not reset between calls to <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG>. However, that fact is not
1287 documented in other implementations. Relying on it will adversely
1288 impact portability to other implementations:
1290 <STRONG>o</STRONG> SVr2 curses supported <EM>dynamic</EM> variables. Those are set only
1291 by a <STRONG>%P</STRONG> operator. A <STRONG>%g</STRONG> for a given variable without first
1292 setting it with <STRONG>%P</STRONG> will give unpredictable results, because
1293 dynamic variables are an uninitialized local array on the
1294 stack in the <STRONG>tparm</STRONG> function.
1296 <STRONG>o</STRONG> SVr3.2 curses supported <EM>static</EM> variables. Those are an array
1297 in the <EM>TERMINAL</EM> structure (declared in <STRONG>term.h</STRONG>), and are zeroed
1298 automatically when the <STRONG>setupterm</STRONG> function allocates the data.
1300 <STRONG>o</STRONG> SVr4 curses made no further improvements to the <EM>dynamic/static</EM>
1303 <STRONG>o</STRONG> Solaris XPG4 curses does not distinguish between <EM>dynamic</EM> and
1304 <EM>static</EM> variables. They are the same. Like SVr4 curses, XPG4
1305 curses does not initialize these explicitly.
1307 <STRONG>o</STRONG> Before version 6.3, <EM>ncurses</EM> stores both <EM>dynamic</EM> and <EM>static</EM>
1308 variables in persistent storage, initialized to zeros.
1310 <STRONG>o</STRONG> Beginning with version 6.3, <EM>ncurses</EM> stores <EM>static</EM> and <EM>dynamic</EM>
1311 variables in the same manner as SVr4.
1313 <STRONG>o</STRONG> Unlike other implementations, <EM>ncurses</EM> zeros dynamic
1314 variables before the first <STRONG>%g</STRONG> or <STRONG>%P</STRONG> operator.
1316 <STRONG>o</STRONG> Like SVr2, the scope of dynamic variables in <EM>ncurses</EM> is
1317 within the current call to <STRONG>tparm</STRONG>. Use static variables if
1318 persistent storage is needed.

1345 This forms an if-then-else. The <STRONG>%e</STRONG> <EM>elsepart</EM> is optional. Usually
1346 the <STRONG>%?</STRONG> <EM>expr</EM> part pushes a value onto the stack, and <STRONG>%t</STRONG> pops it
1347 from the stack, testing if it is nonzero (true). If it is zero
1348 (false), control passes to the <STRONG>%e</STRONG> (else) part.
1350 It is possible to form else-if's a la Algol 68:

1353 where ci are conditions, bi are bodies.
1355 Use the <STRONG>-f</STRONG> option of <STRONG>tic</STRONG> or <STRONG>infocmp</STRONG> to see the structure of if-
1356 then-else's. Some strings, e.g., <STRONG>sgr</STRONG> can be very complicated when
1357 written on one line. The <STRONG>-f</STRONG> option splits the string into lines
1358 with the parts indented.
1360 Binary operations are in postfix form with the operands in the usual
1361 order. That is, to get x-5 one would use "%gx%{5}%-". <STRONG>%P</STRONG> and <STRONG>%g</STRONG>
1362 variables are persistent across escape-string evaluations.
1364 Consider the HP2645, which, to get to row 3 and column 12, needs to be
1365 sent \E&a12c03Y padded for 6 milliseconds. The order of the rows and
1366 columns is inverted here, and the row and column are printed as two
1367 digits. The corresponding terminal description is expressed thus:
1368 cup=\E&a%p2%dc%p1%dY$<6>,
1370 The Microterm ACT-IV needs the current row and column sent preceded by
1371 a <STRONG>^T</STRONG>, with the row and column simply encoded in binary,
1374 Terminals which use "%c" need to be able to backspace the cursor
1375 (<STRONG>cub1</STRONG>), and to move the cursor up one line on the screen (<STRONG>cuu1</STRONG>). This
1376 is necessary because it is not always safe to transmit <STRONG>\n</STRONG> <STRONG>^D</STRONG> and <STRONG>\r</STRONG>, as
1377 the system may change or discard them. (The library routines dealing
1378 with terminfo set tty modes so that tabs are never expanded, so \t is
1379 safe to send. This turns out to be essential for the Ann Arbor 4080.)
1381 A final example is the LSI ADM-3a, which uses row and column offset by
1382 a blank character, thus
1383 cup=\E=%p1%' '%+%c%p2%' '%+%c
1385 After sending "\E=", this pushes the first parameter, pushes the ASCII
1386 value for a space (32), adds them (pushing the sum on the stack in
1387 place of the two previous values) and outputs that value as a
1388 character. Then the same is done for the second parameter. More
1389 complex arithmetic is possible using the stack.

1393 If the terminal has a fast way to home the cursor (to very upper left
1394 corner of screen) then this can be given as <STRONG>home</STRONG>; similarly a fast way
1395 of getting to the lower left-hand corner can be given as <STRONG>ll</STRONG>; this may
1396 involve going up with <STRONG>cuu1</STRONG> from the home position, but a program should
1397 never do this itself (unless <STRONG>ll</STRONG> does) because it can make no assumption
1398 about the effect of moving up from the home position. Note that the
1399 home position is the same as addressing to (0,0): to the top left
1400 corner of the screen, not of memory. (Thus, the \EH sequence on HP
1401 terminals cannot be used for <STRONG>home</STRONG>.)
1403 If the terminal has row or column absolute cursor addressing, these can
1404 be given as single parameter capabilities <STRONG>hpa</STRONG> (horizontal position
1405 absolute) and <STRONG>vpa</STRONG> (vertical position absolute). Sometimes these are
1406 shorter than the more general two parameter sequence (as with the
1407 hp2645) and can be used in preference to <STRONG>cup</STRONG>. If there are
1408 parameterized local motions (e.g., move <EM>n</EM> spaces to the right) these
1409 can be given as <STRONG>cud</STRONG>, <STRONG>cub</STRONG>, <STRONG>cuf</STRONG>, and <STRONG>cuu</STRONG> with a single parameter
1410 indicating how many spaces to move. These are primarily useful if the
1411 terminal does not have <STRONG>cup</STRONG>, such as the TEKTRONIX 4025.
1413 If the terminal needs to be in a special mode when running a program
1414 that uses these capabilities, the codes to enter and exit this mode can
1415 be given as <STRONG>smcup</STRONG> and <STRONG>rmcup</STRONG>. This arises, for example, from terminals
1416 like the Concept with more than one page of memory. If the terminal
1417 has only memory relative cursor addressing and not screen relative
1418 cursor addressing, a one screen-sized window must be fixed into the
1419 terminal for cursor addressing to work properly. This is also used for
1420 the TEKTRONIX 4025, where <STRONG>smcup</STRONG> sets the command character to be the
1421 one used by terminfo. If the <STRONG>smcup</STRONG> sequence will not restore the
1422 screen after an <STRONG>rmcup</STRONG> sequence is output (to the state prior to
1423 outputting <STRONG>rmcup</STRONG>), specify <STRONG>nrrmc</STRONG>.
1426 </PRE><H3><a name="h3-Margins">Margins</a></H3><PRE>
1427 SVr4 (and X/Open Curses) list several string capabilities for setting
1428 margins. Two were intended for use with terminals, and another six
1429 were intended for use with printers.
1431 <STRONG>o</STRONG> The two terminal capabilities assume that the terminal may have the
1432 capability of setting the left and/or right margin at the current
1433 cursor column position.
1435 <STRONG>o</STRONG> The printer capabilities assume that the printer may have two types
1438 <STRONG>o</STRONG> the ability to set a top and/or bottom margin using the current
1441 <STRONG>o</STRONG> parameterized capabilities for setting the top, bottom, left,
1442 right margins given the number of rows or columns.
1444 In practice, the categorization into "terminal" and "printer" is not
1447 <STRONG>o</STRONG> The AT&T SVr4 terminal database uses <STRONG>smgl</STRONG> four times, for AT&T
1450 Three of the four are printers. They lack the ability to set
1451 left/right margins by specifying the column.
1453 <STRONG>o</STRONG> Other (non-AT&T) terminals may support margins but using different
1454 assumptions from AT&T.
1456 For instance, the DEC VT420 supports left/right margins, but only
1457 using a column parameter. As an added complication, the VT420 uses
1458 two settings to fully enable left/right margins (left/right margin
1459 mode, and origin mode). The former enables the margins, which
1460 causes printed text to wrap within margins, but the latter is
1461 needed to prevent cursor-addressing outside those margins.
1463 <STRONG>o</STRONG> Both DEC VT420 left/right margins are set with a single control
1464 sequence. If either is omitted, the corresponding margin is set to
1465 the left or right edge of the display (rather than leaving the

1481 <STRONG>smgtb</STRONG> Set both top and bottom margins to <EM>T</EM> and <EM>B</EM>
1483 When writing an application that uses these string capabilities, the
1484 pairs should be first checked to see if each capability in the pair is
1485 set or only one is set:
1487 <STRONG>o</STRONG> If both <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> are set, each is used with a single
1488 argument, <EM>N</EM>, that gives the column number of the left and right
1489 margin, respectively.
1491 <STRONG>o</STRONG> If both <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG> are set, each is used to set the top and
1492 bottom margin, respectively:
1494 <STRONG>o</STRONG> <STRONG>smgtp</STRONG> is used with a single argument, <EM>N</EM>, the line number of the
1497 <STRONG>o</STRONG> <STRONG>smgbp</STRONG> is used with two arguments, <EM>N</EM> and <EM>M</EM>, that give the line
1498 number of the bottom margin, the first counting from the top of
1499 the page and the second counting from the bottom. This
1500 accommodates the two styles of specifying the bottom margin in
1501 different manufacturers' printers.

1504 bottom margin, only the first or second argument should be used,
1505 depending on the printer. When developing an application that uses
1506 <STRONG>smgbp</STRONG> to set the bottom margin, both arguments must be given.
1508 Conversely, when only one capability in the pair is set:
1510 <STRONG>o</STRONG> If only one of <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> is set, then it is used with two
1511 arguments, the column number of the left and right margins, in that
1514 <STRONG>o</STRONG> Likewise, if only one of <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG> is set, then it is used
1515 with two arguments that give the top and bottom margins, in that
1516 order, counting from the top of the page.
1518 When designing a terminfo entry for a printer that requires setting
1519 both left and right or top and bottom margins simultaneously, only
1520 one capability in the pairs <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> or <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG>
1521 should be defined, leaving the other unset.
1523 Except for very old terminal descriptions, e.g., those developed for
1524 SVr4, the scheme just described should be considered obsolete. An
1525 improved set of capabilities was added late in the SVr4 releases (<STRONG>smglr</STRONG>
1526 and <STRONG>smgtb</STRONG>), which explicitly use two parameters for setting the
1527 left/right or top/bottom margins.
1529 When setting margins, the line- and column-values are zero-based.
1531 The <STRONG>mgc</STRONG> string capability should be defined. Applications such as
1532 <STRONG><A HREF="tabs.1.html">tabs(1)</A></STRONG> rely upon this to reset all margins.

1536 If the terminal can clear from the current position to the end of the
1537 line, leaving the cursor where it is, this should be given as <STRONG>el</STRONG>. If
1538 the terminal can clear from the beginning of the line to the current
1539 position inclusive, leaving the cursor where it is, this should be
1540 given as <STRONG>el1</STRONG>. If the terminal can clear from the current position to
1541 the end of the display, then this should be given as <STRONG>ed</STRONG>. <STRONG>Ed</STRONG> is only
1542 defined from the first column of a line. (Thus, it can be simulated by
1543 a request to delete a large number of lines, if a true <STRONG>ed</STRONG> is not

1548 If the terminal can open a new blank line before the line where the
1549 cursor is, this should be given as <STRONG>il1</STRONG>; this is done only from the
1550 first position of a line. The cursor must then appear on the newly
1551 blank line. If the terminal can delete the line which the cursor is
1552 on, then this should be given as <STRONG>dl1</STRONG>; this is done only from the first
1553 position on the line to be deleted. Versions of <STRONG>il1</STRONG> and <STRONG>dl1</STRONG> which take
1554 a single parameter and insert or delete that many lines can be given as
1555 <STRONG>il</STRONG> and <STRONG>dl</STRONG>.
1557 If the terminal has a settable scrolling region (like the vt100) the
1558 command to set this can be described with the <STRONG>csr</STRONG> capability, which
1559 takes two parameters: the top and bottom lines of the scrolling region.
1560 The cursor position is, alas, undefined after using this command.
1562 It is possible to get the effect of insert or delete line using <STRONG>csr</STRONG> on
1563 a properly chosen region; the <STRONG>sc</STRONG> and <STRONG>rc</STRONG> (save and restore cursor)
1564 commands may be useful for ensuring that your synthesized insert/delete
1565 string does not move the cursor. (Note that the <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> library
1566 does this synthesis automatically, so you need not compose
1567 insert/delete strings for an entry with <STRONG>csr</STRONG>).
1569 Yet another way to construct insert and delete might be to use a
1570 combination of index with the memory-lock feature found on some
1571 terminals (like the HP-700/90 series, which however also has
1574 Inserting lines at the top or bottom of the screen can also be done
1575 using <STRONG>ri</STRONG> or <STRONG>ind</STRONG> on many terminals without a true insert/delete line,
1576 and is often faster even on terminals with those features.
1578 The Boolean <STRONG>non_dest_scroll_region</STRONG> should be set if each scrolling
1579 window is effectively a view port on a screen-sized canvas. To test
1580 for this capability, create a scrolling region in the middle of the
1581 screen, write something to the bottom line, move the cursor to the top
1582 of the region, and do <STRONG>ri</STRONG> followed by <STRONG>dl1</STRONG> or <STRONG>ind</STRONG>. If the data scrolled
1583 off the bottom of the region by the <STRONG>ri</STRONG> re-appears, then scrolling is
1584 non-destructive. System V and XSI Curses expect that <STRONG>ind</STRONG>, <STRONG>ri</STRONG>, <STRONG>indn</STRONG>,
1585 and <STRONG>rin</STRONG> will simulate destructive scrolling; their documentation
1586 cautions you not to define <STRONG>csr</STRONG> unless this is true. This <STRONG>curses</STRONG>
1587 implementation is more liberal and will do explicit erases after
1588 scrolling if <STRONG>ndsrc</STRONG> is defined.
1590 If the terminal has the ability to define a window as part of memory,
1591 which all commands affect, it should be given as the parameterized
1592 string <STRONG>wind</STRONG>. The four parameters are the starting and ending lines in
1593 memory and the starting and ending columns in memory, in that order.
1595 If the terminal can retain display memory above, then the <STRONG>da</STRONG> capability
1596 should be given; if display memory can be retained below, then <STRONG>db</STRONG>
1597 should be given. These indicate that deleting a line or scrolling may
1598 bring non-blank lines up from below or that scrolling back with <STRONG>ri</STRONG> may
1599 bring down non-blank lines.
1602 </PRE><H3><a name="h3-Insert_Delete-Character">Insert/Delete Character</a></H3><PRE>
1603 There are two basic kinds of intelligent terminals with respect to
1604 insert/delete character which can be described using <EM>terminfo.</EM> The
1605 most common insert/delete character operations affect only the
1606 characters on the current line and shift characters off the end of the
1607 line rigidly. Other terminals, such as the Concept 100 and the Perkin
1608 Elmer Owl, make a distinction between typed and untyped blanks on the
1609 screen, shifting upon an insert or delete only to an untyped blank on
1610 the screen which is either eliminated, or expanded to two untyped
1613 You can determine the kind of terminal you have by clearing the screen
1614 and then typing text separated by cursor motions. Type "abc def"
1615 using local cursor motions (not spaces) between the "abc" and the
1616 "def". Then position the cursor before the "abc" and put the terminal
1617 in insert mode. If typing characters causes the rest of the line to
1618 shift rigidly and characters to fall off the end, then your terminal
1619 does not distinguish between blanks and untyped positions. If the
1620 "abc" shifts over to the "def" which then move together around the end
1621 of the current line and onto the next as you insert, you have the
1622 second type of terminal, and should give the capability <STRONG>in</STRONG>, which
1623 stands for "insert null".
1625 While these are two logically separate attributes (one line versus
1626 multi-line insert mode, and special treatment of untyped spaces) we
1627 have seen no terminals whose insert mode cannot be described with the
1630 Terminfo can describe both terminals which have an insert mode, and
1631 terminals which send a simple sequence to open a blank position on the
1632 current line. Give as <STRONG>smir</STRONG> the sequence to get into insert mode. Give
1633 as <STRONG>rmir</STRONG> the sequence to leave insert mode. Now give as <STRONG>ich1</STRONG> any
1634 sequence needed to be sent just before sending the character to be
1635 inserted. Most terminals with a true insert mode will not give <STRONG>ich1</STRONG>;
1636 terminals which send a sequence to open a screen position should give
1639 If your terminal has both, insert mode is usually preferable to <STRONG>ich1</STRONG>.
1640 Technically, you should not give both unless the terminal actually
1641 requires both to be used in combination. Accordingly, some non-curses
1642 applications get confused if both are present; the symptom is doubled
1643 characters in an update using insert. This requirement is now rare;
1644 most <STRONG>ich</STRONG> sequences do not require previous smir, and most smir insert
1645 modes do not require <STRONG>ich1</STRONG> before each character. Therefore, the new
1646 <STRONG>curses</STRONG> actually assumes this is the case and uses either <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> or
1647 <STRONG>ich</STRONG>/<STRONG>ich1</STRONG> as appropriate (but not both). If you have to write an entry
1648 to be used under new curses for a terminal old enough to need both,
1649 include the <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> sequences in <STRONG>ich1</STRONG>.
1651 If post insert padding is needed, give this as a number of milliseconds
1652 in <STRONG>ip</STRONG> (a string option). Any other sequence which may need to be sent
1653 after an insert of a single character may also be given in <STRONG>ip</STRONG>. If your
1654 terminal needs both to be placed into an "insert mode" and a special
1655 code to precede each inserted character, then both <STRONG>smir</STRONG>/<STRONG>rmir</STRONG> and <STRONG>ich1</STRONG>
1656 can be given, and both will be used. The <STRONG>ich</STRONG> capability, with one
1657 parameter, <EM>n</EM>, will repeat the effects of <STRONG>ich1</STRONG> <EM>n</EM> times.
1659 If padding is necessary between characters typed while not in insert
1660 mode, give this as a number of milliseconds padding in <STRONG>rmp</STRONG>.
1662 It is occasionally necessary to move around while in insert mode to
1663 delete characters on the same line (e.g., if there is a tab after the
1664 insertion position). If your terminal allows motion while in insert
1665 mode you can give the capability <STRONG>mir</STRONG> to speed up inserting in this
1666 case. Omitting <STRONG>mir</STRONG> will affect only speed. Some terminals (notably
1667 Datamedia's) must not have <STRONG>mir</STRONG> because of the way their insert mode
1670 Finally, you can specify <STRONG>dch1</STRONG> to delete a single character, <STRONG>dch</STRONG> with
1671 one parameter, <EM>n</EM>, to delete <EM>n</EM> <EM>characters,</EM> and delete mode by giving
1672 <STRONG>smdc</STRONG> and <STRONG>rmdc</STRONG> to enter and exit delete mode (any mode the terminal
1673 needs to be placed in for <STRONG>dch1</STRONG> to work).
1675 A command to erase <EM>n</EM> characters (equivalent to outputting <EM>n</EM> blanks
1676 without moving the cursor) can be given as <STRONG>ech</STRONG> with one parameter.
1679 </PRE><H3><a name="h3-Highlighting_Underlining_and-Visible-Bells">Highlighting, Underlining, and Visible Bells</a></H3><PRE>
1680 If your terminal has one or more kinds of display attributes, these can
1681 be represented in a number of different ways. You should choose one
1682 display form as <EM>standout</EM> <EM>mode</EM>, representing a good, high contrast,
1683 easy-on-the-eyes, format for highlighting error messages and other
1684 attention getters. (If you have a choice, reverse video plus half-
1685 bright is good, or reverse video alone.) The sequences to enter and
1686 exit standout mode are given as <STRONG>smso</STRONG> and <STRONG>rmso</STRONG>, respectively. If the
1687 code to change into or out of standout mode leaves one or even two
1688 blank spaces on the screen, as the TVI 912 and Teleray 1061 do, then
1689 <STRONG>xmc</STRONG> should be given to tell how many spaces are left.
1691 Codes to begin underlining and end underlining can be given as <STRONG>smul</STRONG> and
1692 <STRONG>rmul</STRONG> respectively. If the terminal has a code to underline the current
1693 character and move the cursor one space to the right, such as the
1694 Microterm Mime, this can be given as <STRONG>uc</STRONG>.
1696 Other capabilities to enter various highlighting modes include <STRONG>blink</STRONG>
1697 (blinking) <STRONG>bold</STRONG> (bold or extra bright) <STRONG>dim</STRONG> (dim or half-bright) <STRONG>invis</STRONG>
1698 (blanking or invisible text) <STRONG>prot</STRONG> (protected) <STRONG>rev</STRONG> (reverse video) <STRONG>sgr0</STRONG>
1699 (turn off <EM>all</EM> attribute modes) <STRONG>smacs</STRONG> (enter alternate character set
1700 mode) and <STRONG>rmacs</STRONG> (exit alternate character set mode). Turning on any of
1701 these modes singly may or may not turn off other modes.
1703 If there is a sequence to set arbitrary combinations of modes, this
1704 should be given as <STRONG>sgr</STRONG> (set attributes), taking 9 parameters. Each
1705 parameter is either zero (0) or nonzero, as the corresponding attribute
1706 is on or off. The 9 parameters are, in order: standout, underline,
1707 reverse, blink, dim, bold, blank, protect, alternate character set.
1708 Not all modes need be supported by <STRONG>sgr</STRONG>, only those for which
1709 corresponding separate attribute commands exist.
1711 For example, the DEC vt220 supports most of the modes:
1713 <STRONG>tparm</STRONG> <STRONG>Parameter</STRONG> <STRONG>Attribute</STRONG> <STRONG>Escape</STRONG> <STRONG>Sequence</STRONG>
1714 ------------------------------------------------
1716 p1 standout \E[0;1;7m
1717 p2 underline \E[0;4m
1720 p5 dim not available
1724 p9 altcharset ^O (off) ^N (on)
1726 We begin each escape sequence by turning off any existing modes, since
1727 there is no quick way to determine whether they are active. Standout
1728 is set up to be the combination of reverse and bold. The vt220
1729 terminal has a protect mode, though it is not commonly used in sgr
1730 because it protects characters on the screen from the host's erasures.
1731 The altcharset mode also is different in that it is either ^O or ^N,
1732 depending on whether it is off or on. If all modes are turned on, the
1733 resulting sequence is \E[0;1;4;5;7;8m^N.
1735 Some sequences are common to different modes. For example, ;7 is
1736 output when either p1 or p3 is true, that is, if either standout or
1737 reverse modes are turned on.
1739 Writing out the above sequences, along with their dependencies yields
1741 <STRONG>Sequence</STRONG> <STRONG>When</STRONG> <STRONG>to</STRONG> <STRONG>Output</STRONG> <STRONG>terminfo</STRONG> <STRONG>Translation</STRONG>
1742 ----------------------------------------------------
1744 ;1 if p1 or p6 %?%p1%p6%|%t;1%;
1745 ;4 if p2 %?%p2%|%t;4%;
1746 ;5 if p4 %?%p4%|%t;5%;
1747 ;7 if p1 or p3 %?%p1%p3%|%t;7%;
1748 ;8 if p7 %?%p7%|%t;8%;
1750 ^N or ^O if p9 ^N, else ^O %?%p9%t^N%e^O%;
1752 Putting this all together into the sgr sequence gives:
1754 sgr=\E[0%?%p1%p6%|%t;1%;%?%p2%t;4%;%?%p4%t;5%;
1755 %?%p1%p3%|%t;7%;%?%p7%t;8%;m%?%p9%t\016%e\017%;,
1757 Remember that if you specify sgr, you must also specify sgr0. Also,
1758 some implementations rely on sgr being given if sgr0 is, Not all
1759 terminfo entries necessarily have an sgr string, however. Many
1760 terminfo entries are derived from termcap entries which have no sgr
1761 string. The only drawback to adding an sgr string is that termcap also
1762 assumes that sgr0 does not exit alternate character set mode.
1764 Terminals with the "magic cookie" glitch (<STRONG>xmc</STRONG>) deposit special
1765 "cookies" when they receive mode-setting sequences, which affect the
1766 display algorithm rather than having extra bits for each character.
1767 Some terminals, such as the HP 2621, automatically leave standout mode
1768 when they move to a new line or the cursor is addressed. Programs
1769 using standout mode should exit standout mode before moving the cursor
1770 or sending a newline, unless the <STRONG>msgr</STRONG> capability, asserting that it is
1771 safe to move in standout mode, is present.
1773 If the terminal has a way of flashing the screen to indicate an error
1774 quietly (a bell replacement) then this can be given as <STRONG>flash</STRONG>; it must
1775 not move the cursor.
1777 If the cursor needs to be made more visible than normal when it is not
1778 on the bottom line (to make, for example, a non-blinking underline into
1779 an easier to find block or blinking underline) give this sequence as
1780 <STRONG>cvvis</STRONG>. If there is a way to make the cursor completely invisible, give
1781 that as <STRONG>civis</STRONG>. The capability <STRONG>cnorm</STRONG> should be given which undoes the
1782 effects of both of these modes.
1784 If your terminal correctly generates underlined characters (with no
1785 special codes needed) even though it does not overstrike, then you
1786 should give the capability <STRONG>ul</STRONG>. If a character overstriking another
1787 leaves both characters on the screen, specify the capability <STRONG>os</STRONG>. If
1788 overstrikes are erasable with a blank, then this should be indicated by
1789 giving <STRONG>eo</STRONG>.
1792 </PRE><H3><a name="h3-Keypad-and-Function-Keys">Keypad and Function Keys</a></H3><PRE>
1793 If the terminal has a keypad that transmits codes when the keys are
1794 pressed, this information can be given. Note that it is not possible
1795 to handle terminals where the keypad only works in local (this applies,
1796 for example, to the unshifted HP 2621 keys). If the keypad can be set
1797 to transmit or not transmit, give these codes as <STRONG>smkx</STRONG> and <STRONG>rmkx</STRONG>.
1798 Otherwise the keypad is assumed to always transmit.
1800 The codes sent by the left arrow, right arrow, up arrow, down arrow,
1801 and home keys can be given as <STRONG>kcub1,</STRONG> <STRONG>kcuf1,</STRONG> <STRONG>kcuu1,</STRONG> <STRONG>kcud1,</STRONG> and <STRONG>khome</STRONG>
1802 respectively. If there are function keys such as f0, f1, ..., f10, the
1803 codes they send can be given as <STRONG>kf0,</STRONG> <STRONG>kf1,</STRONG> <STRONG>...,</STRONG> <STRONG>kf10</STRONG>. If these keys
1804 have labels other than the default f0 through f10, the labels can be
1805 given as <STRONG>lf0,</STRONG> <STRONG>lf1,</STRONG> <STRONG>...,</STRONG> <STRONG>lf10</STRONG>.
1807 The codes transmitted by certain other special keys can be given:
1809 <STRONG>o</STRONG> <STRONG>kll</STRONG> (home down),
1811 <STRONG>o</STRONG> <STRONG>kbs</STRONG> (backspace),
1813 <STRONG>o</STRONG> <STRONG>ktbc</STRONG> (clear all tabs),
1815 <STRONG>o</STRONG> <STRONG>kctab</STRONG> (clear the tab stop in this column),
1817 <STRONG>o</STRONG> <STRONG>kclr</STRONG> (clear screen or erase key),
1819 <STRONG>o</STRONG> <STRONG>kdch1</STRONG> (delete character),
1821 <STRONG>o</STRONG> <STRONG>kdl1</STRONG> (delete line),
1823 <STRONG>o</STRONG> <STRONG>krmir</STRONG> (exit insert mode),
1825 <STRONG>o</STRONG> <STRONG>kel</STRONG> (clear to end of line),
1827 <STRONG>o</STRONG> <STRONG>ked</STRONG> (clear to end of screen),
1829 <STRONG>o</STRONG> <STRONG>kich1</STRONG> (insert character or enter insert mode),
1831 <STRONG>o</STRONG> <STRONG>kil1</STRONG> (insert line),
1833 <STRONG>o</STRONG> <STRONG>knp</STRONG> (next page),
1835 <STRONG>o</STRONG> <STRONG>kpp</STRONG> (previous page),
1837 <STRONG>o</STRONG> <STRONG>kind</STRONG> (scroll forward/down),
1839 <STRONG>o</STRONG> <STRONG>kri</STRONG> (scroll backward/up),
1841 <STRONG>o</STRONG> <STRONG>khts</STRONG> (set a tab stop in this column).
1843 In addition, if the keypad has a 3 by 3 array of keys including the
1844 four arrow keys, the other five keys can be given as <STRONG>ka1</STRONG>, <STRONG>ka3</STRONG>, <STRONG>kb2</STRONG>,
1845 <STRONG>kc1</STRONG>, and <STRONG>kc3</STRONG>. These keys are useful when the effects of a 3 by 3
1846 directional pad are needed.
1848 Strings to program function keys can be given as <STRONG>pfkey</STRONG>, <STRONG>pfloc</STRONG>, and <STRONG>pfx</STRONG>.
1849 A string to program screen labels should be specified as <STRONG>pln</STRONG>. Each of
1850 these strings takes two parameters: the function key number to program
1851 (from 0 to 10) and the string to program it with. Function key numbers
1852 out of this range may program undefined keys in a terminal dependent
1853 manner. The difference between the capabilities is that <STRONG>pfkey</STRONG> causes
1854 pressing the given key to be the same as the user typing the given
1855 string; <STRONG>pfloc</STRONG> causes the string to be executed by the terminal in
1856 local; and <STRONG>pfx</STRONG> causes the string to be transmitted to the computer.
1858 The capabilities <STRONG>nlab</STRONG>, <STRONG>lw</STRONG> and <STRONG>lh</STRONG> define the number of programmable
1859 screen labels and their width and height. If there are commands to
1860 turn the labels on and off, give them in <STRONG>smln</STRONG> and <STRONG>rmln</STRONG>. <STRONG>smln</STRONG> is
1861 normally output after one or more pln sequences to make sure that the
1862 change becomes visible.
1865 </PRE><H3><a name="h3-Tabs-and-Initialization">Tabs and Initialization</a></H3><PRE>
1866 A few capabilities are used only for tabs:
1868 <STRONG>o</STRONG> If the terminal has hardware tabs, the command to advance to the
1869 next tab stop can be given as <STRONG>ht</STRONG> (usually control/I).
1871 <STRONG>o</STRONG> A "back-tab" command which moves leftward to the preceding tab stop
1872 can be given as <STRONG>cbt</STRONG>.
1874 By convention, if the teletype modes indicate that tabs are being
1875 expanded by the computer rather than being sent to the terminal,
1876 programs should not use <STRONG>ht</STRONG> or <STRONG>cbt</STRONG> even if they are present, since
1877 the user may not have the tab stops properly set.
1879 <STRONG>o</STRONG> If the terminal has hardware tabs which are initially set every <EM>n</EM>
1880 spaces when the terminal is powered up, the numeric parameter <STRONG>it</STRONG> is
1881 given, showing the number of spaces the tabs are set to.
1883 The <STRONG>it</STRONG> capability is normally used by the <STRONG>tset</STRONG> command to determine
1884 whether to set the mode for hardware tab expansion, and whether to
1885 set the tab stops. If the terminal has tab stops that can be saved
1886 in non-volatile memory, the terminfo description can assume that
1887 they are properly set.
1889 Other capabilities include
1891 <STRONG>o</STRONG> <STRONG>is1</STRONG>, <STRONG>is2</STRONG>, and <STRONG>is3</STRONG>, initialization strings for the terminal,
1893 <STRONG>o</STRONG> <STRONG>iprog</STRONG>, the path name of a program to be run to initialize the
1896 <STRONG>o</STRONG> and <STRONG>if</STRONG>, the name of a file containing long initialization strings.
1898 These strings are expected to set the terminal into modes consistent
1899 with the rest of the terminfo description. They are normally sent to
1900 the terminal, by the <EM>init</EM> option of the <STRONG>tput</STRONG> program, each time the
1901 user logs in. They will be printed in the following order:
1904 <STRONG>iprog</STRONG>
1907 <STRONG>is1</STRONG> and
1908 <STRONG>is2</STRONG>
1910 set the margins using
1911 <STRONG>mgc</STRONG> or
1912 <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> or
1913 <STRONG>smgl</STRONG> and <STRONG>smgr</STRONG>
1916 <STRONG>tbc</STRONG> and <STRONG>hts</STRONG>
1922 <STRONG>is3</STRONG>.
1924 Most initialization is done with <STRONG>is2</STRONG>. Special terminal modes can be
1925 set up without duplicating strings by putting the common sequences in
1926 <STRONG>is2</STRONG> and special cases in <STRONG>is1</STRONG> and <STRONG>is3</STRONG>.
1928 A set of sequences that does a harder reset from a totally unknown
1929 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>
1930 and <STRONG>is3</STRONG> respectively. These strings are output by <EM>reset</EM> option of
1931 <STRONG>tput</STRONG>, or by the <STRONG>reset</STRONG> program (an alias of <STRONG>tset</STRONG>), which is used when
1932 the terminal gets into a wedged state. Commands are normally placed in
1933 <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG> <STRONG>rs3</STRONG> and <STRONG>rf</STRONG> only if they produce annoying effects on the screen
1934 and are not necessary when logging in. For example, the command to set
1935 the vt100 into 80-column mode would normally be part of <STRONG>is2</STRONG>, but it
1936 causes an annoying glitch of the screen and is not normally needed
1937 since the terminal is usually already in 80-column mode.
1939 The <STRONG>reset</STRONG> program writes strings including <STRONG>iprog</STRONG>, etc., in the same
1940 order as the <EM>init</EM> program, using <STRONG>rs1</STRONG>, etc., instead of <STRONG>is1</STRONG>, etc. If
1941 any of <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, or <STRONG>rf</STRONG> reset capability strings are missing, the
1942 <STRONG>reset</STRONG> program falls back upon the corresponding initialization
1945 If there are commands to set and clear tab stops, they can be given as
1946 <STRONG>tbc</STRONG> (clear all tab stops) and <STRONG>hts</STRONG> (set a tab stop in the current column
1947 of every row). If a more complex sequence is needed to set the tabs
1948 than can be described by this, the sequence can be placed in <STRONG>is2</STRONG> or <STRONG>if</STRONG>.
1950 The <STRONG>tput</STRONG> <STRONG>reset</STRONG> command uses the same capability strings as the <STRONG>reset</STRONG>
1951 command, although the two programs (<STRONG>tput</STRONG> and <STRONG>reset</STRONG>) provide different
1952 command-line options.
1954 In practice, these terminfo capabilities are not often used in
1955 initialization of tabs (though they are required for the <STRONG>tabs</STRONG> program):
1957 <STRONG>o</STRONG> Almost all hardware terminals (at least those which supported tabs)
1958 initialized those to every <EM>eight</EM> columns:
1960 The only exception was the AT&T 2300 series, which set tabs to
1961 every <EM>five</EM> columns.
1963 <STRONG>o</STRONG> In particular, developers of the hardware terminals which are
1964 commonly used as models for modern terminal emulators provided
1965 documentation demonstrating that <EM>eight</EM> columns were the standard.
1967 <STRONG>o</STRONG> Because of this, the terminal initialization programs <STRONG>tput</STRONG> and <STRONG>tset</STRONG>
1968 use the <STRONG>tbc</STRONG> (<STRONG>clear_all_tabs</STRONG>) and <STRONG>hts</STRONG> (<STRONG>set_tab</STRONG>) capabilities
1969 directly only when the <STRONG>it</STRONG> (<STRONG>init_tabs</STRONG>) capability is set to a value
1970 other than <EM>eight</EM>.
1973 </PRE><H3><a name="h3-Delays-and-Padding">Delays and Padding</a></H3><PRE>
1974 Many older and slower terminals do not support either XON/XOFF or DTR
1975 handshaking, including hard copy terminals and some very archaic CRTs
1976 (including, for example, DEC VT100s). These may require padding
1977 characters after certain cursor motions and screen changes.
1979 If the terminal uses xon/xoff handshaking for flow control (that is, it
1980 automatically emits ^S back to the host when its input buffers are
1981 close to full), set <STRONG>xon</STRONG>. This capability suppresses the emission of
1982 padding. You can also set it for memory-mapped console devices
1983 effectively that do not have a speed limit. Padding information should
1984 still be included so that routines can make better decisions about
1985 relative costs, but actual pad characters will not be transmitted.
1987 If <STRONG>pb</STRONG> (padding baud rate) is given, padding is suppressed at baud rates
1988 below the value of <STRONG>pb</STRONG>. If the entry has no padding baud rate, then
1989 whether padding is emitted or not is completely controlled by <STRONG>xon</STRONG>.
1991 If the terminal requires other than a null (zero) character as a pad,
1992 then this can be given as <STRONG>pad</STRONG>. Only the first character of the <STRONG>pad</STRONG>
1996 </PRE><H3><a name="h3-Status-Lines">Status Lines</a></H3><PRE>
1997 Some terminals have an extra "status line" which is not normally used
1998 by software (and thus not counted in the terminal's <STRONG>lines</STRONG> capability).
2000 The simplest case is a status line which is cursor-addressable but not
2001 part of the main scrolling region on the screen; the Heathkit H19 has a
2002 status line of this kind, as would a 24-line VT100 with a 23-line
2003 scrolling region set up on initialization. This situation is indicated
2004 by the <STRONG>hs</STRONG> capability.
2006 Some terminals with status lines need special sequences to access the
2007 status line. These may be expressed as a string with single parameter
2008 <STRONG>tsl</STRONG> which takes the cursor to a given zero-origin column on the status
2009 line. The capability <STRONG>fsl</STRONG> must return to the main-screen cursor
2010 positions before the last <STRONG>tsl</STRONG>. You may need to embed the string values
2011 of <STRONG>sc</STRONG> (save cursor) and <STRONG>rc</STRONG> (restore cursor) in <STRONG>tsl</STRONG> and <STRONG>fsl</STRONG> to
2014 The status line is normally assumed to be the same width as the width
2015 of the terminal. If this is untrue, you can specify it with the
2016 numeric capability <STRONG>wsl</STRONG>.
2018 A command to erase or blank the status line may be specified as <STRONG>dsl</STRONG>.
2020 The Boolean capability <STRONG>eslok</STRONG> specifies that escape sequences, tabs,
2021 etc., work ordinarily in the status line.
2023 The <EM>ncurses</EM> implementation does not yet use any of these capabilities.
2024 They are documented here in case they ever become important.

2091 to a copy of this table for your terminal, giving the character which

2093 corresponding graphic. Then read off the VT100/your terminal character

2097 </PRE><H3><a name="h3-Color-Handling">Color Handling</a></H3><PRE>
2098 The curses library functions <STRONG>init_pair</STRONG> and <STRONG>init_color</STRONG> manipulate the
2099 <EM>color</EM> <EM>pairs</EM> and <EM>color</EM> <EM>values</EM> discussed in this section (see
2100 <STRONG><A HREF="curs_color.3x.html">curs_color(3x)</A></STRONG> for details on these and related functions).
2102 Most color terminals are either "Tektronix-like" or "HP-like":
2104 <STRONG>o</STRONG> Tektronix-like terminals have a predefined set of <EM>N</EM> colors (where <EM>N</EM>
2105 is usually 8), and can set character-cell foreground and background
2106 characters independently, mixing them into <EM>N</EM> * <EM>N</EM> color pairs.
2108 <STRONG>o</STRONG> On HP-like terminals, the user must set each color pair up
2109 separately (foreground and background are not independently
2110 settable). Up to <EM>M</EM> color pairs may be set up from 2*<EM>M</EM> different
2111 colors. ANSI-compatible terminals are Tektronix-like.
2113 Some basic color capabilities are independent of the color method. The
2114 numeric capabilities <STRONG>colors</STRONG> and <STRONG>pairs</STRONG> specify the maximum numbers of
2115 colors and color pairs that can be displayed simultaneously. The <STRONG>op</STRONG>
2116 (original pair) string resets foreground and background colors to their
2117 default values for the terminal. The <STRONG>oc</STRONG> string resets all colors or
2118 color pairs to their default values for the terminal. Some terminals
2119 (including many PC terminal emulators) erase screen areas with the
2120 current background color rather than the power-up default background;
2121 these should have the Boolean capability <STRONG>bce</STRONG>.
2123 While the curses library works with <EM>color</EM> <EM>pairs</EM> (reflecting the
2124 inability of some devices to set foreground and background colors
2125 independently), there are separate capabilities for setting these
2128 <STRONG>o</STRONG> To change the current foreground or background color on a
2129 Tektronix-type terminal, use <STRONG>setaf</STRONG> (set ANSI foreground) and <STRONG>setab</STRONG>
2130 (set ANSI background) or <STRONG>setf</STRONG> (set foreground) and <STRONG>setb</STRONG> (set
2131 background). These take one parameter, the color number. The SVr4
2132 documentation describes only <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>; the XPG4 draft says that
2133 "If the terminal supports ANSI escape sequences to set background
2134 and foreground, they should be coded as <STRONG>setaf</STRONG> and <STRONG>setab</STRONG>,
2137 <STRONG>o</STRONG> If the terminal supports other escape sequences to set background
2138 and foreground, they should be coded as <STRONG>setf</STRONG> and <STRONG>setb</STRONG>,
2139 respectively. The <STRONG>vidputs</STRONG> and the <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG> functions use the
2140 <STRONG>setaf</STRONG> and <STRONG>setab</STRONG> capabilities if they are defined.
2142 The <STRONG>setaf</STRONG>/<STRONG>setab</STRONG> and <STRONG>setf</STRONG>/<STRONG>setb</STRONG> capabilities take a single numeric
2143 argument each. Argument values 0-7 of <STRONG>setaf</STRONG>/<STRONG>setab</STRONG> are portably defined
2144 as follows (the middle column is the symbolic #define available in the
2145 header for the <STRONG>curses</STRONG> or <EM>ncurses</EM> libraries). The terminal hardware is
2146 free to map these as it likes, but the RGB values indicate normal
2147 locations in color space.

2174 It is important to not confuse the two sets of color capabilities;
2175 otherwise red/blue will be interchanged on the display.
2177 On an HP-like terminal, use <STRONG>scp</STRONG> with a color pair number parameter to
2178 set which color pair is current.
2180 Some terminals allow the <EM>color</EM> <EM>values</EM> to be modified:
2182 <STRONG>o</STRONG> On a Tektronix-like terminal, the capability <STRONG>ccc</STRONG> may be present to
2183 indicate that colors can be modified. If so, the <STRONG>initc</STRONG> capability
2184 will take a color number (0 to <STRONG>colors</STRONG> - 1)and three more parameters
2185 which describe the color. These three parameters default to being
2186 interpreted as RGB (Red, Green, Blue) values. If the Boolean
2187 capability <STRONG>hls</STRONG> is present, they are instead as HLS (Hue, Lightness,
2188 Saturation) indices. The ranges are terminal-dependent.
2190 <STRONG>o</STRONG> On an HP-like terminal, <STRONG>initp</STRONG> may give a capability for changing a
2191 color pair value. It will take seven parameters; a color pair
2192 number (0 to <STRONG>max_pairs</STRONG> - 1), and two triples describing first
2193 background and then foreground colors. These parameters must be
2194 (Red, Green, Blue) or (Hue, Lightness, Saturation) depending on
2195 <STRONG>hls</STRONG>.
2197 On some color terminals, colors collide with highlights. You can
2198 register these collisions with the <STRONG>ncv</STRONG> capability. This is a bit mask
2199 of attributes not to be used when colors are enabled. The
2200 correspondence with the attributes understood by <STRONG>curses</STRONG> is as follows:
2202 <STRONG>Attribute</STRONG> <STRONG>Bit</STRONG> <STRONG>Decimal</STRONG> <STRONG>Set</STRONG> <STRONG>by</STRONG>

2222 For example, on many IBM PC consoles, the underline attribute collides
2223 with the foreground color blue and is not available in color mode.
2224 These should have an <STRONG>ncv</STRONG> capability of 2.
2226 SVr4 curses does nothing with <STRONG>ncv</STRONG>, <EM>ncurses</EM> recognizes it and optimizes
2227 the output in favor of colors.

2231 If the terminal requires other than a null (zero) character as a pad,
2232 then this can be given as pad. Only the first character of the pad
2233 string is used. If the terminal does not have a pad character, specify
2234 npc. Note that <EM>ncurses</EM> implements the termcap-compatible <STRONG>PC</STRONG> variable;
2235 though the application may set this value to something other than a
2236 null, <EM>ncurses</EM> will test <STRONG>npc</STRONG> first and use napms if the terminal has no
2239 If the terminal can move up or down half a line, this can be indicated
2240 with <STRONG>hu</STRONG> (half-line up) and <STRONG>hd</STRONG> (half-line down). This is primarily
2241 useful for superscripts and subscripts on hard-copy terminals. If a
2242 hard-copy terminal can eject to the next page (form feed), give this as
2243 <STRONG>ff</STRONG> (usually control/L).
2245 If there is a command to repeat a given character a given number of
2246 times (to save time transmitting a large number of identical
2247 characters) this can be indicated with the parameterized string <STRONG>rep</STRONG>.
2248 The first parameter is the character to be repeated and the second is
2249 the number of times to repeat it. Thus, tparm(repeat_char, 'x', 10) is
2250 the same as "xxxxxxxxxx".
2252 If the terminal has a settable command character, such as the TEKTRONIX
2253 4025, this can be indicated with <STRONG>cmdch</STRONG>. A prototype command character
2254 is chosen which is used in all capabilities. This character is given
2255 in the <STRONG>cmdch</STRONG> capability to identify it. The following convention is
2256 supported on some Unix systems: The environment is to be searched for a
2257 <STRONG>CC</STRONG> variable, and if found, all occurrences of the prototype character
2258 are replaced with the character in the environment variable.
2260 Terminal descriptions that do not represent a specific kind of known
2261 terminal, such as <EM>switch</EM>, <EM>dialup</EM>, <EM>patch</EM>, and <EM>network</EM>, should include
2262 the <STRONG>gn</STRONG> (generic) capability so that programs can complain that they do
2263 not know how to talk to the terminal. (This capability does not apply
2264 to <EM>virtual</EM> terminal descriptions for which the escape sequences are
2267 If the terminal has a "meta key" which acts as a shift key, setting the
2268 8th bit of any character transmitted, this fact can be indicated with
2269 <STRONG>km</STRONG>. Otherwise, software will assume that the 8th bit is parity and it
2270 will usually be cleared. If strings exist to turn this "meta mode" on
2271 and off, they can be given as <STRONG>smm</STRONG> and <STRONG>rmm</STRONG>.
2273 If the terminal has more lines of memory than will fit on the screen at
2274 once, the number of lines of memory can be indicated with <STRONG>lm</STRONG>. A value
2275 of <STRONG>lm</STRONG>#0 indicates that the number of lines is not fixed, but that there
2276 is still more memory than fits on the screen.
2278 If the terminal is one of those supported by the Unix virtual terminal
2279 protocol, the terminal number can be given as <STRONG>vt</STRONG>.
2281 Media copy strings which control an auxiliary printer connected to the
2282 terminal can be given as <STRONG>mc0</STRONG>: print the contents of the screen, <STRONG>mc4</STRONG>:
2283 turn off the printer, and <STRONG>mc5</STRONG>: turn on the printer. When the printer
2284 is on, all text sent to the terminal will be sent to the printer. It
2285 is undefined whether the text is also displayed on the terminal screen
2286 when the printer is on. A variation <STRONG>mc5p</STRONG> takes one parameter, and
2287 leaves the printer on for as many characters as the value of the
2288 parameter, then turns the printer off. The parameter should not exceed
2289 255. All text, including <STRONG>mc4</STRONG>, is transparently passed to the printer
2290 while an <STRONG>mc5p</STRONG> is in effect.

2294 Hazeltine terminals, which do not allow "~" characters to be displayed
2295 should indicate <STRONG>hz</STRONG>.
2297 Terminals which ignore a line-feed immediately after an <STRONG>am</STRONG> wrap, such
2298 as the Concept and vt100, should indicate <STRONG>xenl</STRONG>.
2300 If <STRONG>el</STRONG> is required to get rid of standout (instead of merely writing
2301 normal text on top of it), <STRONG>xhp</STRONG> should be given.
2303 Teleray terminals, where tabs turn all characters moved over to blanks,
2304 should indicate <STRONG>xt</STRONG> (destructive tabs). Note: the variable indicating
2305 this is now "dest_tabs_magic_smso"; in older versions, it was
2306 teleray_glitch. This glitch is also taken to mean that it is not
2307 possible to position the cursor on top of a "magic cookie", that to
2308 erase standout mode it is instead necessary to use delete and insert
2309 line. The <EM>ncurses</EM> implementation ignores this glitch.
2311 The Beehive Superbee, which is unable to correctly transmit the escape
2312 or control/C characters, has <STRONG>xsb</STRONG>, indicating that the f1 key is used
2313 for escape and f2 for control/C. (Only certain Superbees have this
2314 problem, depending on the ROM.) Note that in older terminfo versions,
2315 this capability was called "beehive_glitch"; it is now "no_esc_ctl_c".

2318 capabilities of the form <STRONG>x</STRONG><EM>x</EM>.
2321 </PRE><H3><a name="h3-Pitfalls-of-Long-Entries">Pitfalls of Long Entries</a></H3><PRE>
2322 Long terminfo entries are unlikely to be a problem; to date, no entry
2323 has even approached terminfo's 4096-byte string-table maximum.
2324 Unfortunately, the termcap translations are much more strictly limited
2325 (to 1023 bytes), thus termcap translations of long terminfo entries can
2328 The man pages for 4.3BSD and older versions of <STRONG>tgetent</STRONG> instruct the
2329 user to allocate a 1024-byte buffer for the termcap entry. The entry
2330 gets null-terminated by the termcap library, so that makes the maximum
2331 safe length for a termcap entry 1k-1 (1023) bytes. Depending on what
2332 the application and the termcap library being used does, and where in
2333 the termcap file the terminal type that <STRONG>tgetent</STRONG> is searching for is,
2334 several bad things can happen:
2336 <STRONG>o</STRONG> some termcap libraries print a warning message,
2338 <STRONG>o</STRONG> some exit if they find an entry that's longer than 1023 bytes,
2340 <STRONG>o</STRONG> some neither exit nor warn, doing nothing useful, and
2342 <STRONG>o</STRONG> some simply truncate the entries to 1023 bytes.
2344 Some application programs allocate more than the recommended 1K for the
2345 termcap entry; others do not.
2347 Each termcap entry has two important sizes associated with it: before
2348 "tc" expansion, and after "tc" expansion. "tc" is the capability that
2349 tacks on another termcap entry to the end of the current one, to add on
2350 its capabilities. If a termcap entry does not use the "tc" capability,
2351 then of course the two lengths are the same.
2353 The "before tc expansion" length is the most important one, because it
2354 affects more than just users of that particular terminal. This is the
2355 length of the entry as it exists in /etc/termcap, minus the backslash-
2356 newline pairs, which <STRONG>tgetent</STRONG> strips out while reading it. Some termcap
2357 libraries strip off the final newline, too (GNU termcap does not). Now
2360 <STRONG>o</STRONG> a termcap entry before expansion is more than 1023 bytes long,
2362 <STRONG>o</STRONG> and the application has only allocated a 1k buffer,
2364 <STRONG>o</STRONG> and the termcap library (like the one in BSD/OS 1.1 and GNU) reads
2365 the whole entry into the buffer, no matter what its length, to see
2366 if it is the entry it wants,
2368 <STRONG>o</STRONG> and <STRONG>tgetent</STRONG> is searching for a terminal type that either is the
2369 long entry, appears in the termcap file after the long entry, or
2370 does not appear in the file at all (so that <STRONG>tgetent</STRONG> has to search
2371 the whole termcap file).
2373 Then <STRONG>tgetent</STRONG> will overwrite memory, perhaps its stack, and probably
2374 core dump the program. Programs like telnet are particularly
2375 vulnerable; modern telnets pass along values like the terminal type
2376 automatically. The results are almost as undesirable with a termcap
2377 library, like SunOS 4.1.3 and Ultrix 4.4, that prints warning messages
2378 when it reads an overly long termcap entry. If a termcap library
2379 truncates long entries, like OSF/1 3.0, it is immune to dying here but
2380 will return incorrect data for the terminal.
2382 The "after tc expansion" length will have a similar effect to the
2383 above, but only for people who actually set <EM>TERM</EM> to that terminal type,
2384 since <STRONG>tgetent</STRONG> only does "tc" expansion once it is found the terminal
2385 type it was looking for, not while searching.
2387 In summary, a termcap entry that is longer than 1023 bytes can cause,
2388 on various combinations of termcap libraries and applications, a core
2389 dump, warnings, or incorrect operation. If it is too long even before
2390 "tc" expansion, it will have this effect even for users of some other
2391 terminal types and users whose <EM>TERM</EM> variable does not have a termcap
2394 When in -C (translate to termcap) mode, the <EM>ncurses</EM> implementation of
2395 <STRONG><A HREF="tic.1m.html">tic(1m)</A></STRONG> issues warning messages when the pre-tc length of a termcap
2396 translation is too long. The -c (check) option also checks resolved
2397 (after tc expansion) lengths.

2406 Searching for terminal descriptions in <EM>$HOME/.terminfo</EM> and
2407 <EM>TERMINFO</EM><STRONG>_</STRONG><EM>DIRS</EM> is not supported by older implementations.
2409 Some SVr4 <STRONG>curses</STRONG> implementations, and all previous to SVr4, do not
2410 interpret the %A and %O operators in parameter strings.
2412 SVr4/XPG4 do not specify whether <STRONG>msgr</STRONG> licenses movement while in an
2413 alternate-character-set mode (such modes may, among other things, map
2414 CR and NL to characters that do not trigger local motions). The
2415 <EM>ncurses</EM> implementation ignores <STRONG>msgr</STRONG> in <STRONG>ALTCHARSET</STRONG> mode. This raises
2416 the possibility that an XPG4 implementation making the opposite
2417 interpretation may need terminfo entries made for <EM>ncurses</EM> to have <STRONG>msgr</STRONG>
2420 The <EM>ncurses</EM> library handles insert-character and insert-character modes
2421 in a slightly non-standard way to get better update efficiency. See
2422 the <STRONG>Insert/Delete</STRONG> <STRONG>Character</STRONG> subsection above.
2424 The parameter substitutions for <STRONG>set_clock</STRONG> and <STRONG>display_clock</STRONG> are not
2425 documented in SVr4 or the XSI Curses standard. They are deduced from
2426 the documentation for the AT&T 505 terminal.
2428 Be careful assigning the <STRONG>kmous</STRONG> capability. The <EM>ncurses</EM> library wants
2429 to interpret it as <STRONG>KEY_MOUSE</STRONG>, for use by terminals and emulators like
2430 xterm that can return mouse-tracking information in the keyboard-input
2433 X/Open Curses does not mention italics. Portable applications must
2434 assume that numeric capabilities are signed 16-bit values. This
2435 includes the <EM>no</EM><STRONG>_</STRONG><EM>color</EM><STRONG>_</STRONG><EM>video</EM> (<STRONG>ncv</STRONG>) capability. The 32768 mask value
2436 used for italics with <STRONG>ncv</STRONG> can be confused with an absent or cancelled
2437 <STRONG>ncv</STRONG>. If italics should work with colors, then the <STRONG>ncv</STRONG> value must be
2438 specified, even if it is zero.
2440 Different commercial ports of <EM>terminfo</EM> and <EM>curses</EM> support different
2441 subsets of XSI Curses and (in some cases) different extensions. Here
2442 is a summary, accurate as of October 1995, after which the commercial
2443 Unix market contracted and lost diversity.
2445 <STRONG>o</STRONG> SVr4, Solaris, and <EM>ncurses</EM> support all SVr4 capabilities.
2447 <STRONG>o</STRONG> IRIX supports the SVr4 set and adds one undocumented extended
2448 string capability (<STRONG>set_pglen</STRONG>).
2450 <STRONG>o</STRONG> SVr1 and Ultrix support a restricted subset of <EM>terminfo</EM>
2451 capabilities. The Booleans end with <STRONG>xon_xoff</STRONG>; the numerics with
2452 <STRONG>width_status_line</STRONG>; and the strings with <STRONG>prtr_non</STRONG>.
2454 <STRONG>o</STRONG> HP/UX supports the SVr1 subset, plus the SVr[234] numerics
2455 <STRONG>num_labels</STRONG>, <STRONG>label_height</STRONG>, <STRONG>label_width</STRONG>, plus function keys 11
2456 through 63, plus <STRONG>plab_norm</STRONG>, <STRONG>label_on</STRONG>, and <STRONG>label_off</STRONG>, plus a number
2457 of incompatible string table extensions.
2459 <STRONG>o</STRONG> AIX supports the SVr1 subset, plus function keys 11 through 63,
2460 plus a number of incompatible string table extensions.
2462 <STRONG>o</STRONG> OSF/1 supports both the SVr4 set and the AIX extensions.

2467 between commercial Unix systems. At least two implementations of
