65 terminfo - terminal capability data base
69 <H2>SYNOPSIS</H2><PRE>
70 /usr/share/terminfo/*/*
74 <H2>DESCRIPTION</H2><PRE>
75 <EM>Terminfo</EM> is a data base describing terminals, used by
76 screen-oriented programs such as <STRONG><A HREF="nvi.1.html">nvi(1)</A></STRONG>, <STRONG><A HREF="rogue.1.html">rogue(1)</A></STRONG> and
77 libraries such as <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>. <EM>Terminfo</EM> describes termi-
78 nals by giving a set of capabilities which they have, by
79 specifying how to perform screen operations, and by speci-
80 fying padding requirements and initialization sequences.
81 This describes <STRONG>ncurses</STRONG> version 5.9 (patch 20120107).
83 Entries in <EM>terminfo</EM> consist of a sequence of `,' separated
84 fields (embedded commas may be escaped with a backslash or
85 notated as \054). White space after the `,' separator is
86 ignored. The first entry for each terminal gives the
87 names which are known for the terminal, separated by `|'
88 characters. The first name given is the most common
89 abbreviation for the terminal, the last name given should
90 be a long name fully identifying the terminal, and all
91 others are understood as synonyms for the terminal name.
92 All names but the last should be in lower case and contain
93 no blanks; the last name may well contain upper case and
94 blanks for readability.
96 Lines beginning with a `#' in the first column are treated
97 as comments. While comment lines are legal at any point,
98 the output of <STRONG>captoinfo</STRONG> and <STRONG>infotocap</STRONG> (aliases for <STRONG>tic</STRONG>)
99 will move comments so they occur only between entries.
101 Newlines and leading tabs may be used for formatting
102 entries for readability. These are removed from parsed
103 entries. The <STRONG>infocmp</STRONG> <STRONG>-f</STRONG> option relies on this to format
104 if-then-else expressions: the result can be read by <STRONG>tic</STRONG>.
106 Terminal names (except for the last, verbose entry) should
107 be chosen using the following conventions. The particular
108 piece of hardware making up the terminal should have a
109 root name, thus ``hp2621''. This name should not contain
110 hyphens. Modes that the hardware can be in, or user pref-
111 erences, should be indicated by appending a hyphen and a
112 mode suffix. Thus, a vt100 in 132 column mode would be
113 vt100-w. The following suffixes should be used where pos-
117 <STRONG>Suffix</STRONG> <STRONG>Meaning</STRONG> <STRONG>Example</STRONG>
118 -<EM>nn</EM> Number of lines on the screen aaa-60
119 -<EM>n</EM>p Number of pages of memory c100-4p
120 -am With automargins (usually the default) vt100-am
121 -m Mono mode; suppress color ansi-m
122 -mc Magic cookie; spaces when highlighting wy30-mc
123 -na No arrow keys (leave them in local) c100-na
124 -nam Without automatic margins vt100-nam
125 -nl No status line att4415-nl
126 -ns No status line hp2626-ns
127 -rv Reverse video c100-rv
128 -s Enable status line vt100-s
130 -vb Use visible bell instead of beep wy370-vb
131 -w Wide mode (> 80 columns, usually 132) vt100-w

136 <STRONG>Capabilities</STRONG>
137 The following is a complete table of the capabilities
138 included in a terminfo description block and available to
139 terminfo-using code. In each line of the table,
141 The <STRONG>variable</STRONG> is the name by which the programmer (at the
142 terminfo level) accesses the capability.
144 The <STRONG>capname</STRONG> is the short name used in the text of the
145 database, and is used by a person updating the database.
146 Whenever possible, capnames are chosen to be the same as
147 or similar to the ANSI X3.64-1979 standard (now superseded
148 by ECMA-48, which uses identical or very similar names).
149 Semantics are also intended to match those of the specifi-
152 The termcap code is the old <STRONG>termcap</STRONG> capability name (some
153 capabilities are new, and have names which termcap did not
156 Capability names have no hard length limit, but an infor-
157 mal limit of 5 characters has been adopted to keep them
158 short and to allow the tabs in the source file <STRONG>Caps</STRONG> to
161 Finally, the description field attempts to convey the
162 semantics of the capability. You may find some codes in
163 the description field:
165 (P) indicates that padding may be specified
167 #[1-9] in the description field indicates that the string
168 is passed through tparm with parms as given (#<EM>i</EM>).
170 (P*) indicates that padding may vary in proportion to
171 the number of lines affected
173 (#<EM>i</EM>) indicates the <EM>i</EM>th parameter.
176 These are the boolean capabilities:

1053 Comments may be included on lines beginning with ``#''.
1054 Capabilities in <EM>terminfo</EM> are of three types: Boolean capa-
1055 bilities which indicate that the terminal has some partic-
1056 ular feature, numeric capabilities giving the size of the
1057 terminal or the size of particular delays, and string
1058 capabilities, which give a sequence which can be used to
1059 perform particular terminal operations.
1062 <STRONG>Types</STRONG> <STRONG>of</STRONG> <STRONG>Capabilities</STRONG>
1063 All capabilities have names. For instance, the fact that
1064 ANSI-standard terminals have <EM>automatic</EM> <EM>margins</EM> (i.e., an
1065 automatic return and line-feed when the end of a line is
1066 reached) is indicated by the capability <STRONG>am</STRONG>. Hence the
1067 description of ansi includes <STRONG>am</STRONG>. Numeric capabilities are
1068 followed by the character `#' and then a positive value.
1069 Thus <STRONG>cols</STRONG>, which indicates the number of columns the ter-
1070 minal has, gives the value `80' for ansi. Values for
1071 numeric capabilities may be specified in decimal, octal or
1072 hexadecimal, using the C programming language conventions
1073 (e.g., 255, 0377 and 0xff or 0xFF).
1075 Finally, string valued capabilities, such as <STRONG>el</STRONG> (clear to
1076 end of line sequence) are given by the two-character code,
1077 an `=', and then a string ending at the next following
1080 A number of escape sequences are provided in the string
1081 valued capabilities for easy encoding of characters there.
1082 Both <STRONG>\E</STRONG> and <STRONG>\e</STRONG> map to an ESCAPE character, <STRONG>^x</STRONG> maps to a
1083 control-x for any appropriate x, and the sequences <STRONG>\n</STRONG> <STRONG>\l</STRONG>
1084 <STRONG>\r</STRONG> <STRONG>\t</STRONG> <STRONG>\b</STRONG> <STRONG>\f</STRONG> <STRONG>\s</STRONG> give a newline, line-feed, return, tab,
1085 backspace, form-feed, and space. Other escapes include <STRONG>\^</STRONG>
1086 for <STRONG>^</STRONG>, <STRONG>\\</STRONG> for <STRONG>\</STRONG>, <STRONG>\</STRONG>, for comma, <STRONG>\:</STRONG> for <STRONG>:</STRONG>, and <STRONG>\0</STRONG> for null.
1087 (<STRONG>\0</STRONG> will produce \200, which does not terminate a string
1088 but behaves as a null character on most terminals, provid-
1089 ing CS7 is specified. See <STRONG><A HREF="stty.1.html">stty(1)</A></STRONG>.) Finally, characters
1090 may be given as three octal digits after a <STRONG>\</STRONG>.
1092 A delay in milliseconds may appear anywhere in a string
1093 capability, enclosed in $<..> brackets, as in <STRONG>el</STRONG>=\EK$<5>,
1094 and padding characters are supplied by <EM>tputs</EM> to provide
1095 this delay. The delay must be a number with at most one
1096 decimal place of precision; it may be followed by suffixes
1097 `*' or '/' or both. A `*' indicates that the padding
1098 required is proportional to the number of lines affected
1099 by the operation, and the amount given is the per-
1100 affected-unit padding required. (In the case of insert
1101 character, the factor is still the number of <EM>lines</EM>
1102 affected.) Normally, padding is advisory if the device
1103 has the <STRONG>xon</STRONG> capability; it is used for cost computation
1104 but does not trigger delays. A `/' suffix indicates that
1105 the padding is mandatory and forces a delay of the given
1106 number of milliseconds even on devices for which <STRONG>xon</STRONG> is
1107 present to indicate flow control.
1109 Sometimes individual capabilities must be commented out.
1110 To do this, put a period before the capability name. For
1111 example, see the second <STRONG>ind</STRONG> in the example above.
1114 <STRONG>Fetching</STRONG> <STRONG>Compiled</STRONG> <STRONG>Descriptions</STRONG>
1115 If the environment variable TERMINFO is set, it is inter-
1116 preted as the pathname of a directory containing the com-
1117 piled description you are working on. Only that directory
1120 If TERMINFO is not set, the <STRONG>ncurses</STRONG> version of the ter-
1121 minfo reader code will instead look in the directory
1122 <STRONG>$HOME/.terminfo</STRONG> for a compiled description. If it fails
1123 to find one there, and the environment variable TER-
1124 MINFO_DIRS is set, it will interpret the contents of that
1125 variable as a list of colon- separated directories (or
1126 database files) to be searched (an empty entry is inter-
1127 preted as a command to search <EM>/usr/share/terminfo</EM>). If no
1128 description is found in any of the TERMINFO_DIRS directo-
1129 ries, the fetch fails.
1131 If neither TERMINFO nor TERMINFO_DIRS is set, the last
1132 place tried will be the system terminfo directory,
1133 <EM>/usr/share/terminfo</EM>.
1135 (Neither the <STRONG>$HOME/.terminfo</STRONG> lookups nor TERMINFO_DIRS
1136 extensions are supported under stock System V ter-
1140 <STRONG>Preparing</STRONG> <STRONG>Descriptions</STRONG>
1141 We now outline how to prepare descriptions of terminals.
1142 The most effective way to prepare a terminal description
1143 is by imitating the description of a similar terminal in
1144 <EM>terminfo</EM> and to build up a description gradually, using
1145 partial descriptions with <EM>vi</EM> or some other screen-oriented
1146 program to check that they are correct. Be aware that a
1147 very unusual terminal may expose deficiencies in the abil-
1148 ity of the <EM>terminfo</EM> file to describe it or bugs in the
1149 screen-handling code of the test program.
1151 To get the padding for insert line right (if the terminal
1152 manufacturer did not document it) a severe test is to edit
1153 a large file at 9600 baud, delete 16 or so lines from the
1154 middle of the screen, then hit the `u' key several times
1155 quickly. If the terminal messes up, more padding is usu-
1156 ally needed. A similar test can be used for insert char-
1160 <STRONG>Basic</STRONG> <STRONG>Capabilities</STRONG>
1161 The number of columns on each line for the terminal is
1162 given by the <STRONG>cols</STRONG> numeric capability. If the terminal is
1163 a CRT, then the number of lines on the screen is given by
1164 the <STRONG>lines</STRONG> capability. If the terminal wraps around to the
1165 beginning of the next line when it reaches the right mar-
1166 gin, then it should have the <STRONG>am</STRONG> capability. If the termi-
1167 nal can clear its screen, leaving the cursor in the home
1168 position, then this is given by the <STRONG>clear</STRONG> string capabil-
1169 ity. If the terminal overstrikes (rather than clearing a
1170 position when a character is struck over) then it should
1171 have the <STRONG>os</STRONG> capability. If the terminal is a printing
1172 terminal, with no soft copy unit, give it both <STRONG>hc</STRONG> and <STRONG>os</STRONG>.
1173 (<STRONG>os</STRONG> applies to storage scope terminals, such as TEKTRONIX
1174 4010 series, as well as hard copy and APL terminals.) If
1175 there is a code to move the cursor to the left edge of the
1176 current row, give this as <STRONG>cr</STRONG>. (Normally this will be car-
1177 riage return, control M.) If there is a code to produce
1178 an audible signal (bell, beep, etc) give this as <STRONG>bel</STRONG>.
1180 If there is a code to move the cursor one position to the
1181 left (such as backspace) that capability should be given
1182 as <STRONG>cub1</STRONG>. Similarly, codes to move to the right, up, and
1183 down should be given as <STRONG>cuf1</STRONG>, <STRONG>cuu1</STRONG>, and <STRONG>cud1</STRONG>. These local
1184 cursor motions should not alter the text they pass over,
1185 for example, you would not normally use `<STRONG>cuf1</STRONG>= ' because
1186 the space would erase the character moved over.
1188 A very important point here is that the local cursor
1189 motions encoded in <EM>terminfo</EM> are undefined at the left and
1190 top edges of a CRT terminal. Programs should never
1191 attempt to backspace around the left edge, unless <STRONG>bw</STRONG> is
1192 given, and never attempt to go up locally off the top. In
1193 order to scroll text up, a program will go to the bottom
1194 left corner of the screen and send the <STRONG>ind</STRONG> (index) string.
1196 To scroll text down, a program goes to the top left corner
1197 of the screen and sends the <STRONG>ri</STRONG> (reverse index) string.
1198 The strings <STRONG>ind</STRONG> and <STRONG>ri</STRONG> are undefined when not on their
1199 respective corners of the screen.
1201 Parameterized versions of the scrolling sequences are <STRONG>indn</STRONG>
1202 and <STRONG>rin</STRONG> which have the same semantics as <STRONG>ind</STRONG> and <STRONG>ri</STRONG> except
1203 that they take one parameter, and scroll that many lines.
1204 They are also undefined except at the appropriate edge of
1207 The <STRONG>am</STRONG> capability tells whether the cursor sticks at the
1208 right edge of the screen when text is output, but this
1209 does not necessarily apply to a <STRONG>cuf1</STRONG> from the last column.
1210 The only local motion which is defined from the left edge
1211 is if <STRONG>bw</STRONG> is given, then a <STRONG>cub1</STRONG> from the left edge will
1212 move to the right edge of the previous row. If <STRONG>bw</STRONG> is not
1213 given, the effect is undefined. This is useful for draw-
1214 ing a box around the edge of the screen, for example. If
1215 the terminal has switch selectable automatic margins, the
1216 <EM>terminfo</EM> file usually assumes that this is on; i.e., <STRONG>am</STRONG>.
1217 If the terminal has a command which moves to the first
1218 column of the next line, that command can be given as <STRONG>nel</STRONG>
1219 (newline). It does not matter if the command clears the
1220 remainder of the current line, so if the terminal has no
1221 <STRONG>cr</STRONG> and <STRONG>lf</STRONG> it may still be possible to craft a working <STRONG>nel</STRONG>
1222 out of one or both of them.
1224 These capabilities suffice to describe hard-copy and
1225 "glass-tty" terminals. Thus the model 33 teletype is
1228 33|tty33|tty|model 33 teletype,
1229 bel=^G, cols#72, cr=^M, cud1=^J, hc, ind=^J, os,
1231 while the Lear Siegler ADM-3 is described as
1234 am, bel=^G, clear=^Z, cols#80, cr=^M, cub1=^H, cud1=^J,
1238 <STRONG>Parameterized</STRONG> <STRONG>Strings</STRONG>
1239 Cursor addressing and other strings requiring parameters
1240 in the terminal are described by a parameterized string
1241 capability, with <STRONG><A HREF="printf.3.html">printf(3)</A></STRONG> like escapes <STRONG>%x</STRONG> in it. For
1242 example, to address the cursor, the <STRONG>cup</STRONG> capability is
1243 given, using two parameters: the row and column to address
1244 to. (Rows and columns are numbered from zero and refer to
1245 the physical screen visible to the user, not to any unseen
1246 memory.) If the terminal has memory relative cursor
1247 addressing, that can be indicated by <STRONG>mrcup</STRONG>.
1249 The parameter mechanism uses a stack and special <STRONG>%</STRONG> codes
1250 to manipulate it. Typically a sequence will push one of
1251 the parameters onto the stack and then print it in some
1252 format. Print (e.g., "%d") is a special case. Other
1253 operations, including "%t" pop their operand from the
1254 stack. It is noted that more complex operations are often
1255 necessary, e.g., in the <STRONG>sgr</STRONG> string.
1257 The <STRONG>%</STRONG> encodings have the following meanings:
1262 %<EM>[[</EM>:<EM>]flags][width[.precision]][</EM>doxXs<EM>]</EM>
1263 as in <STRONG>printf</STRONG>, flags are [-+#] and space. Use a `:'
1264 to allow the next character to be a `-' flag, avoid-
1265 ing interpreting "%-" as an operator.
1267 %c print pop() like %c in <STRONG>printf</STRONG>
1269 %s print pop() like %s in <STRONG>printf</STRONG>
1272 push <EM>i</EM>'th parameter
1275 set dynamic variable [a-z] to pop()
1278 get dynamic variable [a-z] and push it
1281 set static variable [a-z] to pop()
1284 get static variable [a-z] and push it
1286 The terms "static" and "dynamic" are misleading.
1287 Historically, these are simply two different sets of
1288 variables, whose values are not reset between calls
1289 to <STRONG>tparm</STRONG>. However, that fact is not documented in
1290 other implementations. Relying on it will adversely
1291 impact portability to other implementations.

1320 This forms an if-then-else. The %e <EM>elsepart</EM> is
1321 optional. Usually the %? <EM>expr</EM> part pushes a value
1322 onto the stack, and %t pops it from the stack, test-
1323 ing if it is nonzero (true). If it is zero (false),
1324 control passes to the %e (else) part.
1326 It is possible to form else-if's a la Algol 68:
1327 %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e %;
1329 where ci are conditions, bi are bodies.
1331 Use the <STRONG>-f</STRONG> option of <STRONG>tic</STRONG> or <STRONG>infocmp</STRONG> to see the struc-
1332 ture of if-then-else's. Some strings, e.g., <STRONG>sgr</STRONG> can
1333 be very complicated when written on one line. The <STRONG>-f</STRONG>
1334 option splits the string into lines with the parts
1337 Binary operations are in postfix form with the operands in
1338 the usual order. That is, to get x-5 one would use
1339 "%gx%{5}%-". %P and %g variables are persistent across
1340 escape-string evaluations.
1342 Consider the HP2645, which, to get to row 3 and column 12,
1343 needs to be sent \E&a12c03Y padded for 6 milliseconds.
1344 Note that the order of the rows and columns is inverted
1345 here, and that the row and column are printed as two dig-
1346 its. Thus its <STRONG>cup</STRONG> capability is "cup=6\E&%p2%2dc%p1%2dY".
1348 The Microterm ACT-IV needs the current row and column sent
1349 preceded by a <STRONG>^T</STRONG>, with the row and column simply encoded
1350 in binary, "cup=^T%p1%c%p2%c". Terminals which use "%c"
1351 need to be able to backspace the cursor (<STRONG>cub1</STRONG>), and to
1352 move the cursor up one line on the screen (<STRONG>cuu1</STRONG>). This is
1353 necessary because it is not always safe to transmit <STRONG>\n</STRONG> <STRONG>^D</STRONG>
1354 and <STRONG>\r</STRONG>, as the system may change or discard them. (The
1355 library routines dealing with terminfo set tty modes so
1356 that tabs are never expanded, so \t is safe to send. This
1357 turns out to be essential for the Ann Arbor 4080.)
1359 A final example is the LSI ADM-3a, which uses row and col-
1360 umn offset by a blank character, thus "cup=\E=%p1%'
1361 '%+%c%p2%' '%+%c". After sending `\E=', this pushes the
1362 first parameter, pushes the ASCII value for a space (32),
1363 adds them (pushing the sum on the stack in place of the
1364 two previous values) and outputs that value as a charac-
1365 ter. Then the same is done for the second parameter.
1366 More complex arithmetic is possible using the stack.
1369 <STRONG>Cursor</STRONG> <STRONG>Motions</STRONG>
1370 If the terminal has a fast way to home the cursor (to very
1371 upper left corner of screen) then this can be given as
1372 <STRONG>home</STRONG>; similarly a fast way of getting to the lower left-
1373 hand corner can be given as <STRONG>ll</STRONG>; this may involve going up
1374 with <STRONG>cuu1</STRONG> from the home position, but a program should
1375 never do this itself (unless <STRONG>ll</STRONG> does) because it can make
1376 no assumption about the effect of moving up from the home
1377 position. Note that the home position is the same as
1378 addressing to (0,0): to the top left corner of the screen,
1379 not of memory. (Thus, the \EH sequence on HP terminals
1380 cannot be used for <STRONG>home</STRONG>.)
1382 If the terminal has row or column absolute cursor address-
1383 ing, these can be given as single parameter capabilities
1384 <STRONG>hpa</STRONG> (horizontal position absolute) and <STRONG>vpa</STRONG> (vertical posi-
1385 tion absolute). Sometimes these are shorter than the more
1386 general two parameter sequence (as with the hp2645) and
1387 can be used in preference to <STRONG>cup</STRONG>. If there are parameter-
1388 ized local motions (e.g., move <EM>n</EM> spaces to the right)
1389 these can be given as <STRONG>cud</STRONG>, <STRONG>cub</STRONG>, <STRONG>cuf</STRONG>, and <STRONG>cuu</STRONG> with a single
1390 parameter indicating how many spaces to move. These are
1391 primarily useful if the terminal does not have <STRONG>cup</STRONG>, such
1392 as the TEKTRONIX 4025.
1394 If the terminal needs to be in a special mode when running
1395 a program that uses these capabilities, the codes to enter
1396 and exit this mode can be given as <STRONG>smcup</STRONG> and <STRONG>rmcup</STRONG>. This
1397 arises, for example, from terminals like the Concept with
1398 more than one page of memory. If the terminal has only
1399 memory relative cursor addressing and not screen relative
1400 cursor addressing, a one screen-sized window must be fixed
1401 into the terminal for cursor addressing to work properly.
1402 This is also used for the TEKTRONIX 4025, where <STRONG>smcup</STRONG> sets
1403 the command character to be the one used by terminfo. If
1404 the <STRONG>smcup</STRONG> sequence will not restore the screen after an
1405 <STRONG>rmcup</STRONG> sequence is output (to the state prior to outputting
1406 <STRONG>rmcup</STRONG>), specify <STRONG>nrrmc</STRONG>.
1409 <STRONG>Area</STRONG> <STRONG>Clears</STRONG>
1410 If the terminal can clear from the current position to the
1411 end of the line, leaving the cursor where it is, this
1412 should be given as <STRONG>el</STRONG>. If the terminal can clear from the
1413 beginning of the line to the current position inclusive,
1414 leaving the cursor where it is, this should be given as
1415 <STRONG>el1</STRONG>. If the terminal can clear from the current position
1416 to the end of the display, then this should be given as
1417 <STRONG>ed</STRONG>. <STRONG>Ed</STRONG> is only defined from the first column of a line.
1418 (Thus, it can be simulated by a request to delete a large
1419 number of lines, if a true <STRONG>ed</STRONG> is not available.)
1422 <STRONG>Insert/delete</STRONG> <STRONG>line</STRONG> <STRONG>and</STRONG> <STRONG>vertical</STRONG> <STRONG>motions</STRONG>
1423 If the terminal can open a new blank line before the line
1424 where the cursor is, this should be given as <STRONG>il1</STRONG>; this is
1425 done only from the first position of a line. The cursor
1426 must then appear on the newly blank line. If the terminal
1427 can delete the line which the cursor is on, then this
1428 should be given as <STRONG>dl1</STRONG>; this is done only from the first
1429 position on the line to be deleted. Versions of <STRONG>il1</STRONG> and
1430 <STRONG>dl1</STRONG> which take a single parameter and insert or delete
1431 that many lines can be given as <STRONG>il</STRONG> and <STRONG>dl</STRONG>.
1433 If the terminal has a settable scrolling region (like the
1434 vt100) the command to set this can be described with the
1435 <STRONG>csr</STRONG> capability, which takes two parameters: the top and
1436 bottom lines of the scrolling region. The cursor position
1437 is, alas, undefined after using this command.
1439 It is possible to get the effect of insert or delete line
1440 using <STRONG>csr</STRONG> on a properly chosen region; the <STRONG>sc</STRONG> and <STRONG>rc</STRONG> (save
1441 and restore cursor) commands may be useful for ensuring
1442 that your synthesized insert/delete string does not move
1443 the cursor. (Note that the <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> library does this
1444 synthesis automatically, so you need not compose
1445 insert/delete strings for an entry with <STRONG>csr</STRONG>).
1447 Yet another way to construct insert and delete might be to
1448 use a combination of index with the memory-lock feature
1449 found on some terminals (like the HP-700/90 series, which
1450 however also has insert/delete).
1452 Inserting lines at the top or bottom of the screen can
1453 also be done using <STRONG>ri</STRONG> or <STRONG>ind</STRONG> on many terminals without a
1454 true insert/delete line, and is often faster even on ter-
1455 minals with those features.
1457 The boolean <STRONG>non_dest_scroll_region</STRONG> should be set if each
1458 scrolling window is effectively a view port on a screen-
1459 sized canvas. To test for this capability, create a
1460 scrolling region in the middle of the screen, write some-
1461 thing to the bottom line, move the cursor to the top of
1462 the region, and do <STRONG>ri</STRONG> followed by <STRONG>dl1</STRONG> or <STRONG>ind</STRONG>. If the data
1463 scrolled off the bottom of the region by the <STRONG>ri</STRONG> re-
1464 appears, then scrolling is non-destructive. System V and
1465 XSI Curses expect that <STRONG>ind</STRONG>, <STRONG>ri</STRONG>, <STRONG>indn</STRONG>, and <STRONG>rin</STRONG> will simu-
1466 late destructive scrolling; their documentation cautions
1467 you not to define <STRONG>csr</STRONG> unless this is true. This <STRONG>curses</STRONG>
1468 implementation is more liberal and will do explicit erases
1469 after scrolling if <STRONG>ndstr</STRONG> is defined.
1471 If the terminal has the ability to define a window as part
1472 of memory, which all commands affect, it should be given
1473 as the parameterized string <STRONG>wind</STRONG>. The four parameters are
1474 the starting and ending lines in memory and the starting
1475 and ending columns in memory, in that order.
1477 If the terminal can retain display memory above, then the
1478 <STRONG>da</STRONG> capability should be given; if display memory can be
1479 retained below, then <STRONG>db</STRONG> should be given. These indicate
1480 that deleting a line or scrolling may bring non-blank
1481 lines up from below or that scrolling back with <STRONG>ri</STRONG> may
1482 bring down non-blank lines.
1485 <STRONG>Insert/Delete</STRONG> <STRONG>Character</STRONG>
1486 There are two basic kinds of intelligent terminals with
1487 respect to insert/delete character which can be described
1488 using <EM>terminfo.</EM> The most common insert/delete character
1489 operations affect only the characters on the current line
1490 and shift characters off the end of the line rigidly.
1491 Other terminals, such as the Concept 100 and the Perkin
1492 Elmer Owl, make a distinction between typed and untyped
1493 blanks on the screen, shifting upon an insert or delete
1494 only to an untyped blank on the screen which is either
1495 eliminated, or expanded to two untyped blanks. You can
1496 determine the kind of terminal you have by clearing the
1497 screen and then typing text separated by cursor motions.
1498 Type "abc def" using local cursor motions (not spaces)
1499 between the "abc" and the "def". Then position the cursor
1500 before the "abc" and put the terminal in insert mode. If
1501 typing characters causes the rest of the line to shift
1502 rigidly and characters to fall off the end, then your ter-
1503 minal does not distinguish between blanks and untyped
1504 positions. If the "abc" shifts over to the "def" which
1505 then move together around the end of the current line and
1506 onto the next as you insert, you have the second type of
1507 terminal, and should give the capability <STRONG>in</STRONG>, which stands
1508 for "insert null". While these are two logically separate
1509 attributes (one line versus multi-line insert mode, and
1510 special treatment of untyped spaces) we have seen no ter-
1511 minals whose insert mode cannot be described with the sin-
1514 Terminfo can describe both terminals which have an insert
1515 mode, and terminals which send a simple sequence to open a
1516 blank position on the current line. Give as <STRONG>smir</STRONG> the
1517 sequence to get into insert mode. Give as <STRONG>rmir</STRONG> the
1518 sequence to leave insert mode. Now give as <STRONG>ich1</STRONG> any
1519 sequence needed to be sent just before sending the
1520 character to be inserted. Most terminals with a true
1521 insert mode will not give <STRONG>ich1</STRONG>; terminals which send a
1522 sequence to open a screen position should give it here.
1524 If your terminal has both, insert mode is usually prefer-
1525 able to <STRONG>ich1</STRONG>. Technically, you should not give both
1526 unless the terminal actually requires both to be used in
1527 combination. Accordingly, some non-curses applications
1528 get confused if both are present; the symptom is doubled
1529 characters in an update using insert. This requirement is
1530 now rare; most <STRONG>ich</STRONG> sequences do not require previous smir,
1531 and most smir insert modes do not require <STRONG>ich1</STRONG> before each
1532 character. Therefore, the new <STRONG>curses</STRONG> actually assumes
1533 this is the case and uses either <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> or <STRONG>ich</STRONG>/<STRONG>ich1</STRONG> as
1534 appropriate (but not both). If you have to write an entry
1535 to be used under new curses for a terminal old enough to
1536 need both, include the <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> sequences in <STRONG>ich1</STRONG>.
1538 If post insert padding is needed, give this as a number of
1539 milliseconds in <STRONG>ip</STRONG> (a string option). Any other sequence
1540 which may need to be sent after an insert of a single
1541 character may also be given in <STRONG>ip</STRONG>. If your terminal needs
1542 both to be placed into an `insert mode' and a special code
1543 to precede each inserted character, then both <STRONG>smir</STRONG>/<STRONG>rmir</STRONG>
1544 and <STRONG>ich1</STRONG> can be given, and both will be used. The <STRONG>ich</STRONG>
1545 capability, with one parameter, <EM>n</EM>, will repeat the effects
1546 of <STRONG>ich1</STRONG> <EM>n</EM> times.
1548 If padding is necessary between characters typed while not
1549 in insert mode, give this as a number of milliseconds
1550 padding in <STRONG>rmp</STRONG>.
1552 It is occasionally necessary to move around while in
1553 insert mode to delete characters on the same line (e.g.,
1554 if there is a tab after the insertion position). If your
1555 terminal allows motion while in insert mode you can give
1556 the capability <STRONG>mir</STRONG> to speed up inserting in this case.
1557 Omitting <STRONG>mir</STRONG> will affect only speed. Some terminals
1558 (notably Datamedia's) must not have <STRONG>mir</STRONG> because of the way
1559 their insert mode works.
1561 Finally, you can specify <STRONG>dch1</STRONG> to delete a single charac-
1562 ter, <STRONG>dch</STRONG> with one parameter, <EM>n</EM>, to delete <EM>n</EM> <EM>characters,</EM>
1563 and delete mode by giving <STRONG>smdc</STRONG> and <STRONG>rmdc</STRONG> to enter and exit
1564 delete mode (any mode the terminal needs to be placed in
1565 for <STRONG>dch1</STRONG> to work).
1567 A command to erase <EM>n</EM> characters (equivalent to outputting
1568 <EM>n</EM> blanks without moving the cursor) can be given as <STRONG>ech</STRONG>
1572 <STRONG>Highlighting,</STRONG> <STRONG>Underlining,</STRONG> <STRONG>and</STRONG> <STRONG>Visible</STRONG> <STRONG>Bells</STRONG>
1573 If your terminal has one or more kinds of display
1574 attributes, these can be represented in a number of dif-
1575 ferent ways. You should choose one display form as <EM>stand-</EM>
1576 <EM>out</EM> <EM>mode</EM>, representing a good, high contrast, easy-on-the-
1577 eyes, format for highlighting error messages and other
1578 attention getters. (If you have a choice, reverse video
1579 plus half-bright is good, or reverse video alone.) The
1580 sequences to enter and exit standout mode are given as
1581 <STRONG>smso</STRONG> and <STRONG>rmso</STRONG>, respectively. If the code to change into
1582 or out of standout mode leaves one or even two blank
1583 spaces on the screen, as the TVI 912 and Teleray 1061 do,
1584 then <STRONG>xmc</STRONG> should be given to tell how many spaces are left.
1586 Codes to begin underlining and end underlining can be
1587 given as <STRONG>smul</STRONG> and <STRONG>rmul</STRONG> respectively. If the terminal has
1588 a code to underline the current character and move the
1589 cursor one space to the right, such as the Microterm Mime,
1590 this can be given as <STRONG>uc</STRONG>.
1592 Other capabilities to enter various highlighting modes
1593 include <STRONG>blink</STRONG> (blinking) <STRONG>bold</STRONG> (bold or extra bright) <STRONG>dim</STRONG>
1594 (dim or half-bright) <STRONG>invis</STRONG> (blanking or invisible text)
1595 <STRONG>prot</STRONG> (protected) <STRONG>rev</STRONG> (reverse video) <STRONG>sgr0</STRONG> (turn off <EM>all</EM>
1596 attribute modes) <STRONG>smacs</STRONG> (enter alternate character set
1597 mode) and <STRONG>rmacs</STRONG> (exit alternate character set mode).
1598 Turning on any of these modes singly may or may not turn
1601 If there is a sequence to set arbitrary combinations of
1602 modes, this should be given as <STRONG>sgr</STRONG> (set attributes), tak-
1603 ing 9 parameters. Each parameter is either 0 or nonzero,
1604 as the corresponding attribute is on or off. The 9 param-
1605 eters are, in order: standout, underline, reverse, blink,
1606 dim, bold, blank, protect, alternate character set. Not
1607 all modes need be supported by <STRONG>sgr</STRONG>, only those for which
1608 corresponding separate attribute commands exist.
1610 For example, the DEC vt220 supports most of the modes:
1613 <STRONG>tparm</STRONG> <STRONG>parameter</STRONG> <STRONG>attribute</STRONG> <STRONG>escape</STRONG> <STRONG>sequence</STRONG>
1616 p1 standout \E[0;1;7m
1617 p2 underline \E[0;4m
1620 p5 dim not available
1624 p9 altcharset ^O (off) ^N (on)
1626 We begin each escape sequence by turning off any existing
1627 modes, since there is no quick way to determine whether
1628 they are active. Standout is set up to be the combination
1629 of reverse and bold. The vt220 terminal has a protect
1630 mode, though it is not commonly used in sgr because it
1631 protects characters on the screen from the host's era-
1632 sures. The altcharset mode also is different in that it
1633 is either ^O or ^N, depending on whether it is off or on.
1634 If all modes are turned on, the resulting sequence is
1637 Some sequences are common to different modes. For exam-
1638 ple, ;7 is output when either p1 or p3 is true, that is,
1639 if either standout or reverse modes are turned on.
1641 Writing out the above sequences, along with their depen-
1645 <STRONG>sequence</STRONG> <STRONG>when</STRONG> <STRONG>to</STRONG> <STRONG>output</STRONG> <STRONG>terminfo</STRONG> <STRONG>translation</STRONG>
1648 ;1 if p1 or p6 %?%p1%p6%|%t;1%;
1649 ;4 if p2 %?%p2%|%t;4%;
1650 ;5 if p4 %?%p4%|%t;5%;
1651 ;7 if p1 or p3 %?%p1%p3%|%t;7%;
1652 ;8 if p7 %?%p7%|%t;8%;
1655 ^N or ^O if p9 ^N, else ^O %?%p9%t^N%e^O%;
1657 Putting this all together into the sgr sequence gives:
1659 sgr=\E[0%?%p1%p6%|%t;1%;%?%p2%t;4%;%?%p1%p3%|%t;7%;
1660 %?%p4%t;5%;%?%p7%t;8%;m%?%p9%t\016%e\017%;,
1662 Remember that if you specify sgr, you must also specify
1663 sgr0. Also, some implementations rely on sgr being given
1664 if sgr0 is, Not all terminfo entries necessarily have an
1665 sgr string, however. Many terminfo entries are derived
1666 from termcap entries which have no sgr string. The only
1667 drawback to adding an sgr string is that termcap also
1668 assumes that sgr0 does not exit alternate character set
1671 Terminals with the ``magic cookie'' glitch (<STRONG>xmc</STRONG>) deposit
1672 special ``cookies'' when they receive mode-setting
1673 sequences, which affect the display algorithm rather than
1674 having extra bits for each character. Some terminals,
1675 such as the HP 2621, automatically leave standout mode
1676 when they move to a new line or the cursor is addressed.
1677 Programs using standout mode should exit standout mode
1678 before moving the cursor or sending a newline, unless the
1679 <STRONG>msgr</STRONG> capability, asserting that it is safe to move in
1680 standout mode, is present.
1682 If the terminal has a way of flashing the screen to indi-
1683 cate an error quietly (a bell replacement) then this can
1684 be given as <STRONG>flash</STRONG>; it must not move the cursor.
1686 If the cursor needs to be made more visible than normal
1687 when it is not on the bottom line (to make, for example, a
1688 non-blinking underline into an easier to find block or
1689 blinking underline) give this sequence as <STRONG>cvvis</STRONG>. If there
1690 is a way to make the cursor completely invisible, give
1691 that as <STRONG>civis</STRONG>. The capability <STRONG>cnorm</STRONG> should be given which
1692 undoes the effects of both of these modes.
1694 If your terminal correctly generates underlined characters
1695 (with no special codes needed) even though it does not
1696 overstrike, then you should give the capability <STRONG>ul</STRONG>. If a
1697 character overstriking another leaves both characters on
1698 the screen, specify the capability <STRONG>os</STRONG>. If overstrikes are
1699 erasable with a blank, then this should be indicated by
1700 giving <STRONG>eo</STRONG>.
1703 <STRONG>Keypad</STRONG> <STRONG>and</STRONG> <STRONG>Function</STRONG> <STRONG>Keys</STRONG>
1704 If the terminal has a keypad that transmits codes when the
1705 keys are pressed, this information can be given. Note
1706 that it is not possible to handle terminals where the key-
1707 pad only works in local (this applies, for example, to the
1708 unshifted HP 2621 keys). If the keypad can be set to
1709 transmit or not transmit, give these codes as <STRONG>smkx</STRONG> and
1710 <STRONG>rmkx</STRONG>. Otherwise the keypad is assumed to always transmit.
1711 The codes sent by the left arrow, right arrow, up arrow,
1712 down arrow, and home keys can be given as <STRONG>kcub1,</STRONG> <STRONG>kcuf1,</STRONG>
1713 <STRONG>kcuu1,</STRONG> <STRONG>kcud1,</STRONG> and <STRONG>khome</STRONG> respectively. If there are func-
1714 tion keys such as f0, f1, ..., f10, the codes they send
1715 can be given as <STRONG>kf0,</STRONG> <STRONG>kf1,</STRONG> <STRONG>...,</STRONG> <STRONG>kf10</STRONG>. If these keys have
1716 labels other than the default f0 through f10, the labels
1717 can be given as <STRONG>lf0,</STRONG> <STRONG>lf1,</STRONG> <STRONG>...,</STRONG> <STRONG>lf10</STRONG>. The codes transmit-
1718 ted by certain other special keys can be given: <STRONG>kll</STRONG> (home
1719 down), <STRONG>kbs</STRONG> (backspace), <STRONG>ktbc</STRONG> (clear all tabs), <STRONG>kctab</STRONG>
1720 (clear the tab stop in this column), <STRONG>kclr</STRONG> (clear screen or
1721 erase key), <STRONG>kdch1</STRONG> (delete character), <STRONG>kdl1</STRONG> (delete line),
1722 <STRONG>krmir</STRONG> (exit insert mode), <STRONG>kel</STRONG> (clear to end of line), <STRONG>ked</STRONG>
1723 (clear to end of screen), <STRONG>kich1</STRONG> (insert character or enter
1724 insert mode), <STRONG>kil1</STRONG> (insert line), <STRONG>knp</STRONG> (next page), <STRONG>kpp</STRONG>
1725 (previous page), <STRONG>kind</STRONG> (scroll forward/down), <STRONG>kri</STRONG> (scroll
1726 backward/up), <STRONG>khts</STRONG> (set a tab stop in this column). In
1727 addition, if the keypad has a 3 by 3 array of keys includ-
1728 ing the four arrow keys, the other five keys can be given
1729 as <STRONG>ka1</STRONG>, <STRONG>ka3</STRONG>, <STRONG>kb2</STRONG>, <STRONG>kc1</STRONG>, and <STRONG>kc3</STRONG>. These keys are useful
1730 when the effects of a 3 by 3 directional pad are needed.
1732 Strings to program function keys can be given as <STRONG>pfkey</STRONG>,
1733 <STRONG>pfloc</STRONG>, and <STRONG>pfx</STRONG>. A string to program screen labels should
1734 be specified as <STRONG>pln</STRONG>. Each of these strings takes two
1735 parameters: the function key number to program (from 0 to
1736 10) and the string to program it with. Function key num-
1737 bers out of this range may program undefined keys in a
1738 terminal dependent manner. The difference between the
1739 capabilities is that <STRONG>pfkey</STRONG> causes pressing the given key
1740 to be the same as the user typing the given string; <STRONG>pfloc</STRONG>
1741 causes the string to be executed by the terminal in local;
1742 and <STRONG>pfx</STRONG> causes the string to be transmitted to the com-
1745 The capabilities <STRONG>nlab</STRONG>, <STRONG>lw</STRONG> and <STRONG>lh</STRONG> define the number of pro-
1746 grammable screen labels and their width and height. If
1747 there are commands to turn the labels on and off, give
1748 them in <STRONG>smln</STRONG> and <STRONG>rmln</STRONG>. <STRONG>smln</STRONG> is normally output after one
1749 or more pln sequences to make sure that the change becomes
1753 <STRONG>Tabs</STRONG> <STRONG>and</STRONG> <STRONG>Initialization</STRONG>
1754 If the terminal has hardware tabs, the command to advance
1755 to the next tab stop can be given as <STRONG>ht</STRONG> (usually control
1756 I). A ``back-tab'' command which moves leftward to the
1757 preceding tab stop can be given as <STRONG>cbt</STRONG>. By convention, if
1758 the teletype modes indicate that tabs are being expanded
1759 by the computer rather than being sent to the terminal,
1760 programs should not use <STRONG>ht</STRONG> or <STRONG>cbt</STRONG> even if they are
1761 present, since the user may not have the tab stops prop-
1762 erly set. If the terminal has hardware tabs which are
1763 initially set every <EM>n</EM> spaces when the terminal is powered
1764 up, the numeric parameter <STRONG>it</STRONG> is given, showing the number
1765 of spaces the tabs are set to. This is normally used by
1766 the <EM>tset</EM> command to determine whether to set the mode for
1767 hardware tab expansion, and whether to set the tab stops.
1768 If the terminal has tab stops that can be saved in non-
1769 volatile memory, the terminfo description can assume that
1770 they are properly set.
1772 Other capabilities include <STRONG>is1</STRONG>, <STRONG>is2</STRONG>, and <STRONG>is3</STRONG>, initializa-
1773 tion strings for the terminal, <STRONG>iprog</STRONG>, the path name of a
1774 program to be run to initialize the terminal, and <STRONG>if</STRONG>, the
1775 name of a file containing long initialization strings.
1776 These strings are expected to set the terminal into modes
1777 consistent with the rest of the terminfo description.
1778 They are normally sent to the terminal, by the <EM>init</EM> option
1779 of the <EM>tput</EM> program, each time the user logs in. They
1780 will be printed in the following order:
1783 <STRONG>iprog</STRONG>
1785 output <STRONG>is1</STRONG> <STRONG>is2</STRONG>
1787 set the margins using
1788 <STRONG>mgc</STRONG>, <STRONG>smgl</STRONG> and <STRONG>smgr</STRONG>
1791 <STRONG>tbc</STRONG> and <STRONG>hts</STRONG>
1797 output <STRONG>is3</STRONG>.
1799 Most initialization is done with <STRONG>is2</STRONG>. Special terminal
1800 modes can be set up without duplicating strings by putting
1801 the common sequences in <STRONG>is2</STRONG> and special cases in <STRONG>is1</STRONG> and
1802 <STRONG>is3</STRONG>.
1804 A set of sequences that does a harder reset from a totally
1805 unknown state can be given as <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rf</STRONG> and <STRONG>rs3</STRONG>, analo-
1806 gous to <STRONG>is1</STRONG> <STRONG>,</STRONG> <STRONG>is2</STRONG> <STRONG>,</STRONG> <STRONG>if</STRONG> and <STRONG>is3</STRONG> respectively. These
1807 strings are output by the <EM>reset</EM> program, which is used
1808 when the terminal gets into a wedged state. Commands are
1809 normally placed in <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG> <STRONG>rs3</STRONG> and <STRONG>rf</STRONG> only if they pro-
1810 duce annoying effects on the screen and are not necessary
1811 when logging in. For example, the command to set the
1812 vt100 into 80-column mode would normally be part of <STRONG>is2</STRONG>,
1813 but it causes an annoying glitch of the screen and is not
1814 normally needed since the terminal is usually already in
1817 The <EM>reset</EM> program writes strings including <STRONG>iprog</STRONG>, etc., in
1818 the same order as the <EM>init</EM> program, using <STRONG>rs1</STRONG>, etc.,
1819 instead of <STRONG>is1</STRONG>, etc. If any of <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, or <STRONG>rf</STRONG> reset
1820 capability strings are missing, the <EM>reset</EM> program falls
1821 back upon the corresponding initialization capability
1824 If there are commands to set and clear tab stops, they can
1825 be given as <STRONG>tbc</STRONG> (clear all tab stops) and <STRONG>hts</STRONG> (set a tab
1826 stop in the current column of every row). If a more com-
1827 plex sequence is needed to set the tabs than can be
1828 described by this, the sequence can be placed in <STRONG>is2</STRONG> or
1829 <STRONG>if</STRONG>.
1831 <STRONG>Delays</STRONG> <STRONG>and</STRONG> <STRONG>Padding</STRONG>
1832 Many older and slower terminals do not support either
1833 XON/XOFF or DTR handshaking, including hard copy terminals
1834 and some very archaic CRTs (including, for example, DEC
1835 VT100s). These may require padding characters after cer-
1836 tain cursor motions and screen changes.
1838 If the terminal uses xon/xoff handshaking for flow control
1839 (that is, it automatically emits ^S back to the host when
1840 its input buffers are close to full), set <STRONG>xon</STRONG>. This capa-
1841 bility suppresses the emission of padding. You can also
1842 set it for memory-mapped console devices effectively that
1843 do not have a speed limit. Padding information should
1844 still be included so that routines can make better deci-
1845 sions about relative costs, but actual pad characters will
1848 If <STRONG>pb</STRONG> (padding baud rate) is given, padding is suppressed
1849 at baud rates below the value of <STRONG>pb</STRONG>. If the entry has no
1850 padding baud rate, then whether padding is emitted or not
1851 is completely controlled by <STRONG>xon</STRONG>.
1853 If the terminal requires other than a null (zero) charac-
1854 ter as a pad, then this can be given as <STRONG>pad</STRONG>. Only the
1855 first character of the <STRONG>pad</STRONG> string is used.
1858 <STRONG>Status</STRONG> <STRONG>Lines</STRONG>
1859 Some terminals have an extra `status line' which is not
1860 normally used by software (and thus not counted in the
1861 terminal's <STRONG>lines</STRONG> capability).
1863 The simplest case is a status line which is cursor-
1864 addressable but not part of the main scrolling region on
1865 the screen; the Heathkit H19 has a status line of this
1866 kind, as would a 24-line VT100 with a 23-line scrolling
1867 region set up on initialization. This situation is indi-
1868 cated by the <STRONG>hs</STRONG> capability.
1870 Some terminals with status lines need special sequences to
1871 access the status line. These may be expressed as a
1872 string with single parameter <STRONG>tsl</STRONG> which takes the cursor to
1873 a given zero-origin column on the status line. The capa-
1874 bility <STRONG>fsl</STRONG> must return to the main-screen cursor positions
1875 before the last <STRONG>tsl</STRONG>. You may need to embed the string
1876 values of <STRONG>sc</STRONG> (save cursor) and <STRONG>rc</STRONG> (restore cursor) in <STRONG>tsl</STRONG>
1877 and <STRONG>fsl</STRONG> to accomplish this.
1879 The status line is normally assumed to be the same width
1880 as the width of the terminal. If this is untrue, you can
1881 specify it with the numeric capability <STRONG>wsl</STRONG>.
1883 A command to erase or blank the status line may be speci-
1884 fied as <STRONG>dsl</STRONG>.
1886 The boolean capability <STRONG>eslok</STRONG> specifies that escape
1887 sequences, tabs, etc., work ordinarily in the status line.
1889 The <STRONG>ncurses</STRONG> implementation does not yet use any of these
1890 capabilities. They are documented here in case they ever
1894 <STRONG>Line</STRONG> <STRONG>Graphics</STRONG>
1895 Many terminals have alternate character sets useful for
1896 forms-drawing. Terminfo and <STRONG>curses</STRONG> build in support for
1897 the drawing characters supported by the VT100, with some
1898 characters from the AT&T 4410v1 added. This alternate
1899 character set may be specified by the <STRONG>acsc</STRONG> capability.

1938 The best way to define a new device's graphics set is to
1939 add a column to a copy of this table for your terminal,
1940 giving the character which (when emitted between
1941 <STRONG>smacs</STRONG>/<STRONG>rmacs</STRONG> switches) will be rendered as the correspond-
1942 ing graphic. Then read off the VT100/your terminal char-
1943 acter pairs right to left in sequence; these become the
1947 <STRONG>Color</STRONG> <STRONG>Handling</STRONG>
1948 Most color terminals are either `Tektronix-like' or `HP-
1949 like'. Tektronix-like terminals have a predefined set of
1950 N colors (where N usually 8), and can set character-cell
1951 foreground and background characters independently, mixing
1952 them into N * N color-pairs. On HP-like terminals, the
1953 use must set each color pair up separately (foreground and
1954 background are not independently settable). Up to M
1955 color-pairs may be set up from 2*M different colors.
1956 ANSI-compatible terminals are Tektronix-like.
1958 Some basic color capabilities are independent of the color
1959 method. The numeric capabilities <STRONG>colors</STRONG> and <STRONG>pairs</STRONG> specify
1960 the maximum numbers of colors and color-pairs that can be
1961 displayed simultaneously. The <STRONG>op</STRONG> (original pair) string
1962 resets foreground and background colors to their default
1963 values for the terminal. The <STRONG>oc</STRONG> string resets all colors
1964 or color-pairs to their default values for the terminal.
1965 Some terminals (including many PC terminal emulators)
1966 erase screen areas with the current background color
1967 rather than the power-up default background; these should
1968 have the boolean capability <STRONG>bce</STRONG>.
1970 To change the current foreground or background color on a
1971 Tektronix-type terminal, use <STRONG>setaf</STRONG> (set ANSI foreground)
1972 and <STRONG>setab</STRONG> (set ANSI background) or <STRONG>setf</STRONG> (set foreground)
1973 and <STRONG>setb</STRONG> (set background). These take one parameter, the
1974 color number. The SVr4 documentation describes only
1975 <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>; the XPG4 draft says that "If the terminal
1976 supports ANSI escape sequences to set background and fore-
1977 ground, they should be coded as <STRONG>setaf</STRONG> and <STRONG>setab</STRONG>, respec-
1978 tively. If the terminal supports other escape sequences
1979 to set background and foreground, they should be coded as
1980 <STRONG>setf</STRONG> and <STRONG>setb</STRONG>, respectively. The <EM>vidputs()</EM> function and
1981 the refresh functions use <STRONG>setaf</STRONG> and <STRONG>setab</STRONG> if they are
1984 The <STRONG>setaf</STRONG>/<STRONG>setab</STRONG> and <STRONG>setf</STRONG>/<STRONG>setb</STRONG> capabilities take a single
1985 numeric argument each. Argument values 0-7 of <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>
1986 are portably defined as follows (the middle column is the
1987 symbolic #define available in the header for the <STRONG>curses</STRONG> or
1988 <STRONG>ncurses</STRONG> libraries). The terminal hardware is free to map
1989 these as it likes, but the RGB values indicate normal
1990 locations in color space.
1993 <STRONG>Color</STRONG> <STRONG>#define</STRONG> <STRONG>Value</STRONG> <STRONG>RGB</STRONG>
1994 black <STRONG>COLOR_BLACK</STRONG> 0 0, 0, 0
1995 red <STRONG>COLOR_RED</STRONG> 1 max,0,0
1996 green <STRONG>COLOR_GREEN</STRONG> 2 0,max,0
1997 yellow <STRONG>COLOR_YELLOW</STRONG> 3 max,max,0
1998 blue <STRONG>COLOR_BLUE</STRONG> 4 0,0,max
1999 magenta <STRONG>COLOR_MAGENTA</STRONG> 5 max,0,max
2000 cyan <STRONG>COLOR_CYAN</STRONG> 6 0,max,max
2001 white <STRONG>COLOR_WHITE</STRONG> 7 max,max,max
2003 The argument values of <STRONG>setf</STRONG>/<STRONG>setb</STRONG> historically correspond
2004 to a different mapping, i.e.,
2006 <STRONG>Color</STRONG> <STRONG>#define</STRONG> <STRONG>Value</STRONG> <STRONG>RGB</STRONG>
2007 black <STRONG>COLOR_BLACK</STRONG> 0 0, 0, 0
2008 blue <STRONG>COLOR_BLUE</STRONG> 1 0,0,max
2009 green <STRONG>COLOR_GREEN</STRONG> 2 0,max,0
2010 cyan <STRONG>COLOR_CYAN</STRONG> 3 0,max,max
2011 red <STRONG>COLOR_RED</STRONG> 4 max,0,0
2012 magenta <STRONG>COLOR_MAGENTA</STRONG> 5 max,0,max
2013 yellow <STRONG>COLOR_YELLOW</STRONG> 6 max,max,0
2014 white <STRONG>COLOR_WHITE</STRONG> 7 max,max,max
2015 It is important to not confuse the two sets of color capa-
2016 bilities; otherwise red/blue will be interchanged on the
2019 On an HP-like terminal, use <STRONG>scp</STRONG> with a color-pair number
2020 parameter to set which color pair is current.
2022 On a Tektronix-like terminal, the capability <STRONG>ccc</STRONG> may be
2023 present to indicate that colors can be modified. If so,
2024 the <STRONG>initc</STRONG> capability will take a color number (0 to <STRONG>colors</STRONG>
2025 - 1)and three more parameters which describe the color.
2026 These three parameters default to being interpreted as RGB
2027 (Red, Green, Blue) values. If the boolean capability <STRONG>hls</STRONG>
2028 is present, they are instead as HLS (Hue, Lightness, Satu-
2029 ration) indices. The ranges are terminal-dependent.
2031 On an HP-like terminal, <STRONG>initp</STRONG> may give a capability for
2032 changing a color-pair value. It will take seven parame-
2033 ters; a color-pair number (0 to <STRONG>max_pairs</STRONG> - 1), and two
2034 triples describing first background and then foreground
2035 colors. These parameters must be (Red, Green, Blue) or
2036 (Hue, Lightness, Saturation) depending on <STRONG>hls</STRONG>.
2038 On some color terminals, colors collide with highlights.
2039 You can register these collisions with the <STRONG>ncv</STRONG> capability.
2040 This is a bit-mask of attributes not to be used when col-
2041 ors are enabled. The correspondence with the attributes
2042 understood by <STRONG>curses</STRONG> is as follows:
2045 <STRONG>Attribute</STRONG> <STRONG>Bit</STRONG> <STRONG>Decimal</STRONG>
2056 For example, on many IBM PC consoles, the underline
2057 attribute collides with the foreground color blue and is
2058 not available in color mode. These should have an <STRONG>ncv</STRONG>
2061 SVr4 curses does nothing with <STRONG>ncv</STRONG>, ncurses recognizes it
2062 and optimizes the output in favor of colors.
2065 <STRONG>Miscellaneous</STRONG>
2066 If the terminal requires other than a null (zero) charac-
2067 ter as a pad, then this can be given as pad. Only the
2068 first character of the pad string is used. If the termi-
2069 nal does not have a pad character, specify npc. Note that
2070 ncurses implements the termcap-compatible <STRONG>PC</STRONG> variable;
2071 though the application may set this value to something
2072 other than a null, ncurses will test <STRONG>npc</STRONG> first and use
2073 napms if the terminal has no pad character.
2075 If the terminal can move up or down half a line, this can
2076 be indicated with <STRONG>hu</STRONG> (half-line up) and <STRONG>hd</STRONG> (half-line
2077 down). This is primarily useful for superscripts and sub-
2078 scripts on hard-copy terminals. If a hard-copy terminal
2079 can eject to the next page (form feed), give this as <STRONG>ff</STRONG>
2080 (usually control L).
2082 If there is a command to repeat a given character a given
2083 number of times (to save time transmitting a large number
2084 of identical characters) this can be indicated with the
2085 parameterized string <STRONG>rep</STRONG>. The first parameter is the
2086 character to be repeated and the second is the number of
2087 times to repeat it. Thus, tparm(repeat_char, 'x', 10) is
2088 the same as `xxxxxxxxxx'.
2090 If the terminal has a settable command character, such as
2091 the TEKTRONIX 4025, this can be indicated with <STRONG>cmdch</STRONG>. A
2092 prototype command character is chosen which is used in all
2093 capabilities. This character is given in the <STRONG>cmdch</STRONG> capa-
2094 bility to identify it. The following convention is sup-
2095 ported on some UNIX systems: The environment is to be
2096 searched for a <STRONG>CC</STRONG> variable, and if found, all occurrences
2097 of the prototype character are replaced with the character
2098 in the environment variable.
2100 Terminal descriptions that do not represent a specific
2101 kind of known terminal, such as <EM>switch</EM>, <EM>dialup</EM>, <EM>patch</EM>, and
2102 <EM>network</EM>, should include the <STRONG>gn</STRONG> (generic) capability so
2103 that programs can complain that they do not know how to
2104 talk to the terminal. (This capability does not apply to
2105 <EM>virtual</EM> terminal descriptions for which the escape
2106 sequences are known.)
2108 If the terminal has a ``meta key'' which acts as a shift
2109 key, setting the 8th bit of any character transmitted,
2110 this fact can be indicated with <STRONG>km</STRONG>. Otherwise, software
2111 will assume that the 8th bit is parity and it will usually
2112 be cleared. If strings exist to turn this ``meta mode''
2113 on and off, they can be given as <STRONG>smm</STRONG> and <STRONG>rmm</STRONG>.
2115 If the terminal has more lines of memory than will fit on
2116 the screen at once, the number of lines of memory can be
2117 indicated with <STRONG>lm</STRONG>. A value of <STRONG>lm</STRONG>#0 indicates that the
2118 number of lines is not fixed, but that there is still more
2119 memory than fits on the screen.
2121 If the terminal is one of those supported by the UNIX vir-
2122 tual terminal protocol, the terminal number can be given
2123 as <STRONG>vt</STRONG>.
2125 Media copy strings which control an auxiliary printer con-
2126 nected to the terminal can be given as <STRONG>mc0</STRONG>: print the con-
2127 tents of the screen, <STRONG>mc4</STRONG>: turn off the printer, and <STRONG>mc5</STRONG>:
2128 turn on the printer. When the printer is on, all text
2129 sent to the terminal will be sent to the printer. It is
2130 undefined whether the text is also displayed on the termi-
2131 nal screen when the printer is on. A variation <STRONG>mc5p</STRONG> takes
2132 one parameter, and leaves the printer on for as many char-
2133 acters as the value of the parameter, then turns the
2134 printer off. The parameter should not exceed 255. All
2135 text, including <STRONG>mc4</STRONG>, is transparently passed to the
2136 printer while an <STRONG>mc5p</STRONG> is in effect.
2139 <STRONG>Glitches</STRONG> <STRONG>and</STRONG> <STRONG>Braindamage</STRONG>
2140 Hazeltine terminals, which do not allow `~' characters to
2141 be displayed should indicate <STRONG>hz</STRONG>.
2143 Terminals which ignore a line-feed immediately after an <STRONG>am</STRONG>
2144 wrap, such as the Concept and vt100, should indicate <STRONG>xenl</STRONG>.
2146 If <STRONG>el</STRONG> is required to get rid of standout (instead of
2147 merely writing normal text on top of it), <STRONG>xhp</STRONG> should be
2150 Teleray terminals, where tabs turn all characters moved
2151 over to blanks, should indicate <STRONG>xt</STRONG> (destructive tabs).
2152 Note: the variable indicating this is now
2153 `dest_tabs_magic_smso'; in older versions, it was tel-
2154 eray_glitch. This glitch is also taken to mean that it is
2155 not possible to position the cursor on top of a ``magic
2156 cookie'', that to erase standout mode it is instead neces-
2157 sary to use delete and insert line. The ncurses implemen-
2158 tation ignores this glitch.
2160 The Beehive Superbee, which is unable to correctly trans-
2161 mit the escape or control C characters, has <STRONG>xsb</STRONG>, indicat-
2162 ing that the f1 key is used for escape and f2 for control
2163 C. (Only certain Superbees have this problem, depending
2164 on the ROM.) Note that in older terminfo versions, this
2165 capability was called `beehive_glitch'; it is now
2168 Other specific terminal problems may be corrected by
2169 adding more capabilities of the form <STRONG>x</STRONG><EM>x</EM>.
2172 <STRONG>Similar</STRONG> <STRONG>Terminals</STRONG>
2173 If there are two very similar terminals, one (the variant)
2174 can be defined as being just like the other (the base)
2175 with certain exceptions. In the definition of the vari-
2176 ant, the string capability <STRONG>use</STRONG> can be given with the name
2177 of the base terminal. The capabilities given before <STRONG>use</STRONG>
2178 override those in the base type named by <STRONG>use</STRONG>. If there
2179 are multiple <STRONG>use</STRONG> capabilities, they are merged in reverse
2180 order. That is, the rightmost <STRONG>use</STRONG> reference is processed
2181 first, then the one to its left, and so forth. Capabili-
2182 ties given explicitly in the entry override those brought
2183 in by <STRONG>use</STRONG> references.
2185 A capability can be canceled by placing <STRONG>xx@</STRONG> to the left of
2186 the use reference that imports it, where <EM>xx</EM> is the capa-
2187 bility. For example, the entry
2189 2621-nl, smkx@, rmkx@, use=2621,
2191 defines a 2621-nl that does not have the <STRONG>smkx</STRONG> or <STRONG>rmkx</STRONG>
2192 capabilities, and hence does not turn on the function key
2193 labels when in visual mode. This is useful for different
2194 modes for a terminal, or for different user preferences.
2197 <STRONG>Pitfalls</STRONG> <STRONG>of</STRONG> <STRONG>Long</STRONG> <STRONG>Entries</STRONG>
2198 Long terminfo entries are unlikely to be a problem; to
2199 date, no entry has even approached terminfo's 4096-byte
2200 string-table maximum. Unfortunately, the termcap transla-
2201 tions are much more strictly limited (to 1023 bytes), thus
2202 termcap translations of long terminfo entries can cause
2205 The man pages for 4.3BSD and older versions of <STRONG>tgetent()</STRONG>
2206 instruct the user to allocate a 1024-byte buffer for the
2207 termcap entry. The entry gets null-terminated by the
2208 termcap library, so that makes the maximum safe length for
2209 a termcap entry 1k-1 (1023) bytes. Depending on what the
2210 application and the termcap library being used does, and
2211 where in the termcap file the terminal type that <STRONG>tgetent()</STRONG>
2212 is searching for is, several bad things can happen.
2214 Some termcap libraries print a warning message or exit if
2215 they find an entry that's longer than 1023 bytes; others
2216 do not; others truncate the entries to 1023 bytes. Some
2217 application programs allocate more than the recommended 1K
2218 for the termcap entry; others do not.
2220 Each termcap entry has two important sizes associated with
2221 it: before "tc" expansion, and after "tc" expansion. "tc"
2222 is the capability that tacks on another termcap entry to
2223 the end of the current one, to add on its capabilities.
2224 If a termcap entry does not use the "tc" capability, then
2225 of course the two lengths are the same.
2227 The "before tc expansion" length is the most important
2228 one, because it affects more than just users of that par-
2229 ticular terminal. This is the length of the entry as it
2230 exists in /etc/termcap, minus the backslash-newline pairs,
2231 which <STRONG>tgetent()</STRONG> strips out while reading it. Some termcap
2232 libraries strip off the final newline, too (GNU termcap
2233 does not). Now suppose:
2235 * a termcap entry before expansion is more than 1023
2238 * and the application has only allocated a 1k buffer,
2240 * and the termcap library (like the one in BSD/OS 1.1
2241 and GNU) reads the whole entry into the buffer, no
2242 matter what its length, to see if it is the entry it
2245 * and <STRONG>tgetent()</STRONG> is searching for a terminal type that
2246 either is the long entry, appears in the termcap file
2247 after the long entry, or does not appear in the file
2248 at all (so that <STRONG>tgetent()</STRONG> has to search the whole
2251 Then <STRONG>tgetent()</STRONG> will overwrite memory, perhaps its stack,
2252 and probably core dump the program. Programs like telnet
2253 are particularly vulnerable; modern telnets pass along
2254 values like the terminal type automatically. The results
2255 are almost as undesirable with a termcap library, like
2256 SunOS 4.1.3 and Ultrix 4.4, that prints warning messages
2257 when it reads an overly long termcap entry. If a termcap
2258 library truncates long entries, like OSF/1 3.0, it is
2259 immune to dying here but will return incorrect data for
2262 The "after tc expansion" length will have a similar effect
2263 to the above, but only for people who actually set TERM to
2264 that terminal type, since <STRONG>tgetent()</STRONG> only does "tc" expan-
2265 sion once it is found the terminal type it was looking
2266 for, not while searching.
2268 In summary, a termcap entry that is longer than 1023 bytes
2269 can cause, on various combinations of termcap libraries
2270 and applications, a core dump, warnings, or incorrect
2271 operation. If it is too long even before "tc" expansion,
2272 it will have this effect even for users of some other ter-
2273 minal types and users whose TERM variable does not have a
2276 When in -C (translate to termcap) mode, the <STRONG>ncurses</STRONG> imple-
2277 mentation of <STRONG><A HREF="tic.1m.html">tic(1m)</A></STRONG> issues warning messages when the pre-
2278 tc length of a termcap translation is too long. The -c
2279 (check) option also checks resolved (after tc expansion)
2282 <STRONG>Binary</STRONG> <STRONG>Compatibility</STRONG>
2283 It is not wise to count on portability of binary terminfo
2284 entries between commercial UNIX versions. The problem is
2285 that there are at least two versions of terminfo (under
2286 HP-UX and AIX) which diverged from System V terminfo after
2287 SVr1, and have added extension capabilities to the string
2288 table that (in the binary format) collide with System V
2289 and XSI Curses extensions.
2293 <H2>EXTENSIONS</H2><PRE>
2294 Some SVr4 <STRONG>curses</STRONG> implementations, and all previous to
2295 SVr4, do not interpret the %A and %O operators in parame-
2298 SVr4/XPG4 do not specify whether <STRONG>msgr</STRONG> licenses movement
2299 while in an alternate-character-set mode (such modes may,
2300 among other things, map CR and NL to characters that do
2301 not trigger local motions). The <STRONG>ncurses</STRONG> implementation
2302 ignores <STRONG>msgr</STRONG> in <STRONG>ALTCHARSET</STRONG> mode. This raises the possi-
2303 bility that an XPG4 implementation making the opposite
2304 interpretation may need terminfo entries made for <STRONG>ncurses</STRONG>
2305 to have <STRONG>msgr</STRONG> turned off.
2307 The <STRONG>ncurses</STRONG> library handles insert-character and insert-
2308 character modes in a slightly non-standard way to get bet-
2309 ter update efficiency. See the <STRONG>Insert/Delete</STRONG> <STRONG>Character</STRONG>
2312 The parameter substitutions for <STRONG>set_clock</STRONG> and <STRONG>dis-</STRONG>
2313 <STRONG>play_clock</STRONG> are not documented in SVr4 or the XSI Curses
2314 standard. They are deduced from the documentation for the
2315 AT&T 505 terminal.
2317 Be careful assigning the <STRONG>kmous</STRONG> capability. The <STRONG>ncurses</STRONG>
2318 wants to interpret it as <STRONG>KEY_MOUSE</STRONG>, for use by terminals
2319 and emulators like xterm that can return mouse-tracking
2320 information in the keyboard-input stream.
2322 Different commercial ports of terminfo and curses support
2323 different subsets of the XSI Curses standard and (in some
2324 cases) different extension sets. Here is a summary, accu-
2325 rate as of October 1995:
2327 <STRONG>SVR4,</STRONG> <STRONG>Solaris,</STRONG> <STRONG>ncurses</STRONG> -- These support all SVr4 capabili-
2330 <STRONG>SGI</STRONG> -- Supports the SVr4 set, adds one undocumented
2331 extended string capability (<STRONG>set_pglen</STRONG>).
2333 <STRONG>SVr1,</STRONG> <STRONG>Ultrix</STRONG> -- These support a restricted subset of ter-
2334 minfo capabilities. The booleans end with <STRONG>xon_xoff</STRONG>; the
2335 numerics with <STRONG>width_status_line</STRONG>; and the strings with
2336 <STRONG>prtr_non</STRONG>.
2338 <STRONG>HP/UX</STRONG> -- Supports the SVr1 subset, plus the SVr[234]
2339 numerics <STRONG>num_labels</STRONG>, <STRONG>label_height</STRONG>, <STRONG>label_width</STRONG>, plus func-
2340 tion keys 11 through 63, plus <STRONG>plab_norm</STRONG>, <STRONG>label_on</STRONG>, and
2341 <STRONG>label_off</STRONG>, plus some incompatible extensions in the string
2344 <STRONG>AIX</STRONG> -- Supports the SVr1 subset, plus function keys 11
2345 through 63, plus a number of incompatible string table
2348 <STRONG>OSF</STRONG> -- Supports both the SVr4 set and the AIX extensions.
