DESCRIPTION

12       Terminfo  is  a data base describing terminals, used by screen-oriented
13       programs such as nvi(1), rogue(1) and  libraries  such  as  curses(3X).
14       Terminfo describes terminals by giving a set of capabilities which they
15       have, by specifying how to perform screen operations, and by specifying
16       padding  requirements  and  initialization  sequences.   This describes
17       ncurses version 5.7 (patch 20090207).
18
19       Entries in terminfo consist of  a  sequence  of  `,'  separated  fields
20       (embedded  commas  may be escaped with a backslash or notated as \054).
21       White space after the `,' separator is ignored.  The  first  entry  for
22       each  terminal  gives the names which are known for the terminal, sepa‐
23       rated by `|' characters.  The first  name  given  is  the  most  common
24       abbreviation  for  the  terminal,  the last name given should be a long
25       name fully identifying the terminal, and all others are  understood  as
26       synonyms  for  the  terminal name.  All names but the last should be in
27       lower case and contain no blanks; the last name may well contain  upper
28       case and blanks for readability.
29
30       Lines beginning with a `#' in the first column are treated as comments.
31       While comment lines are legal at any point, the output of captoinfo and
32       infotocap  (aliases  for  tic)  will  move  comments so they occur only
33       between entries.
34
35       Newlines and leading tabs may be used for formatting entries for  read‐
36       ability.  These are removed from parsed entries.  The infocmp -f option
37       relies on this to format if-then-else expressions: the  result  can  be
38       read by tic.
39
40       Terminal  names  (except  for the last, verbose entry) should be chosen
41       using the following conventions.  The particular piece of hardware mak‐
42       ing  up  the  terminal  should have a root name, thus ``hp2621''.  This
43       name should not contain hyphens.  Modes that the hardware can be in, or
44       user  preferences, should be indicated by appending a hyphen and a mode
45       suffix.  Thus, a vt100 in 132 column mode would be vt100-w.   The  fol‐
46       lowing suffixes should be used where possible:
47
48            Suffix                  Meaning                   Example
49            -nn      Number of lines on the screen            aaa-60
50            -np      Number of pages of memory                c100-4p
51            -am      With automargins (usually the default)   vt100-am
52            -m       Mono mode; suppress color                ansi-m
53            -mc      Magic cookie; spaces when highlighting   wy30-mc
54            -na      No arrow keys (leave them in local)      c100-na
55            -nam     Without automatic margins                vt100-nam
56            -nl      No status line                           att4415-nl
57            -ns      No status line                           hp2626-ns
58            -rv      Reverse video                            c100-rv
59            -s       Enable status line                       vt100-s
60            -vb      Use visible bell instead of beep         wy370-vb
61            -w       Wide mode (> 80 columns, usually 132)    vt100-w

65   Capabilities
66       The  following  is  a  complete table of the capabilities included in a
67       terminfo description block and available to  terminfo-using  code.   In
68       each line of the table,
69
70       The  variable  is  the  name  by  which the programmer (at the terminfo
71       level) accesses the capability.
72
73       The capname is the short name used in the text of the database, and  is
74       used  by  a  person updating the database.  Whenever possible, capnames
75       are chosen to be the same as or similar to the ANSI X3.64-1979 standard
76       (now  superseded  by  ECMA-48,  which  uses  identical  or very similar
77       names).  Semantics are also intended to match those of  the  specifica‐
78       tion.
79
80       The  termcap code is the old termcap capability name (some capabilities
81       are new, and have names which termcap did not originate).
82
83       Capability names have no hard length limit, but an informal limit of  5
84       characters has been adopted to keep them short and to allow the tabs in
85       the source file Caps to line up nicely.
86
87       Finally, the description field attempts to convey the semantics of  the
88       capability.  You may find some codes in the description field:
89
90       (P)    indicates that padding may be specified
91
92       #[1-9] in  the  description  field  indicates that the string is passed
93              through tparm with parms as given (#i).
94
95       (P*)   indicates that padding may vary in proportion to the  number  of
96              lines affected
97
98       (#i)   indicates the ith parameter.
99

101       These are the boolean capabilities:

914        The  XSI Curses standard added these.  They are some post-4.1 versions
915        of System V curses, e.g., Solaris 2.5 and IRIX 6.x.  The ncurses term‐
916        cap names for them are invented; according to the XSI Curses standard,
917        they have no termcap names.  If your  compiled  terminfo  entries  use
918        these,  they  may  not  be  binary-compatible  with  System V terminfo
919        entries after SVr4.1; beware!

972       Entries may continue onto multiple lines by placing white space at  the
973       beginning  of  each line except the first.  Comments may be included on
974       lines beginning with ``#''.  Capabilities  in  terminfo  are  of  three
975       types:  Boolean  capabilities which indicate that the terminal has some
976       particular feature, numeric capabilities giving the size of the  termi‐
977       nal  or  the  size of particular delays, and string capabilities, which
978       give a sequence which can be used to perform particular terminal opera‐
979       tions.
980
981   Types of Capabilities
982       All capabilities have names.  For instance, the fact that ANSI-standard
983       terminals have automatic margins (i.e., an automatic return  and  line-
984       feed  when the end of a line is reached) is indicated by the capability
985       am.  Hence the description of ansi includes am.   Numeric  capabilities
986       are  followed  by  the  character  `#' and then a positive value.  Thus
987       cols, which indicates the number of columns the terminal has, gives the
988       value  `80' for ansi.  Values for numeric capabilities may be specified
989       in decimal, octal or hexadecimal, using the C programming language con‐
990       ventions (e.g., 255, 0377 and 0xff or 0xFF).
991
992       Finally,  string  valued capabilities, such as el (clear to end of line
993       sequence) are given by the two-character  code,  an  `=',  and  then  a
994       string ending at the next following `,'.
995
996       A number of escape sequences are provided in the string valued capabil‐
997       ities for easy encoding of characters there.  Both \E and \e map to  an
998       ESCAPE character, ^x maps to a control-x for any appropriate x, and the
999       sequences \n \l \r \t \b \f \s give a newline, line-feed, return,  tab,
1000       backspace,  form-feed,  and  space.  Other escapes include \^ for ^, \\
1001       for \, \, for comma, \: for :, and \0 for null.  (\0 will produce \200,
1002       which  does  not  terminate a string but behaves as a null character on
1003       most terminals, providing CS7 is specified.   See  stty(1).)   Finally,
1004       characters may be given as three octal digits after a \.
1005
1006       A  delay  in  milliseconds  may appear anywhere in a string capability,
1007       enclosed in $<..> brackets, as in el=\EK$<5>,  and  padding  characters
1008       are  supplied by tputs to provide this delay.  The delay must be a num‐
1009       ber with at most one decimal place of precision; it may be followed  by
1010       suffixes `*' or '/' or both.  A `*' indicates that the padding required
1011       is proportional to the number of lines affected by the  operation,  and
1012       the  amount  given  is the per-affected-unit padding required.  (In the
1013       case of insert character, the factor  is  still  the  number  of  lines
1014       affected.)   Normally,  padding  is  advisory if the device has the xon
1015       capability; it is used  for  cost  computation  but  does  not  trigger
1016       delays.   A  `/'  suffix  indicates  that  the padding is mandatory and
1017       forces a delay of the given number of milliseconds even on devices  for
1018       which xon is present to indicate flow control.
1019
1020       Sometimes  individual  capabilities must be commented out.  To do this,
1021       put a period before the capability name.  For example, see  the  second
1022       ind in the example above.
1023
1024   Fetching Compiled Descriptions
1025       If  the  environment variable TERMINFO is set, it is interpreted as the
1026       pathname of a directory containing the  compiled  description  you  are
1027       working on.  Only that directory is searched.
1028
1029       If TERMINFO is not set, the ncurses version of the terminfo reader code
1030       will instead look in  the  directory  $HOME/.terminfo  for  a  compiled
1031       description.   If it fails to find one there, and the environment vari‐
1032       able TERMINFO_DIRS is set, it will interpret the contents of that vari‐
1033       able as a list of colon- separated directories to be searched (an empty
1034       entry is interpreted as a command to search  /usr/share/terminfo).   If
1035       no  description  is  found in any of the TERMINFO_DIRS directories, the
1036       fetch fails.
1037
1038       If neither TERMINFO nor TERMINFO_DIRS is set, the last place tried will
1039       be the system terminfo directory, /usr/share/terminfo.
1040
1041       (Neither  the  $HOME/.terminfo lookups nor TERMINFO_DIRS extensions are
1042       supported under stock System V terminfo/curses.)
1043
1044   Preparing Descriptions
1045       We now outline how to prepare  descriptions  of  terminals.   The  most
1046       effective  way  to  prepare  a terminal description is by imitating the
1047       description of a similar  terminal  in  terminfo  and  to  build  up  a
1048       description gradually, using partial descriptions with vi or some other
1049       screen-oriented program to check that they are correct.  Be aware  that
1050       a  very  unusual terminal may expose deficiencies in the ability of the
1051       terminfo file to describe it or bugs in the screen-handling code of the
1052       test program.
1053
1054       To  get the padding for insert line right (if the terminal manufacturer
1055       did not document it) a severe test is to edit  a  large  file  at  9600
1056       baud, delete 16 or so lines from the middle of the screen, then hit the
1057       `u' key several times quickly.  If the terminal messes up, more padding
1058       is usually needed.  A similar test can be used for insert character.
1059
1060   Basic Capabilities
1061       The  number  of  columns  on each line for the terminal is given by the
1062       cols numeric capability.  If the terminal is a CRT, then the number  of
1063       lines  on the screen is given by the lines capability.  If the terminal
1064       wraps around to the beginning of the next  line  when  it  reaches  the
1065       right  margin,  then it should have the am capability.  If the terminal
1066       can clear its screen, leaving the cursor in  the  home  position,  then
1067       this  is  given  by the clear string capability.  If the terminal over‐
1068       strikes (rather than clearing a position when  a  character  is  struck
1069       over)  then  it  should  have  the os capability.  If the terminal is a
1070       printing terminal, with no soft copy unit, give it both hc and os.  (os
1071       applies  to  storage scope terminals, such as TEKTRONIX 4010 series, as
1072       well as hard copy and APL terminals.)  If there is a code to  move  the
1073       cursor to the left edge of the current row, give this as cr.  (Normally
1074       this will be carriage return, control M.)  If there is a code  to  pro‐
1075       duce an audible signal (bell, beep, etc) give this as bel.
1076
1077       If there is a code to move the cursor one position to the left (such as
1078       backspace) that capability should be given as cub1.   Similarly,  codes
1079       to  move  to the right, up, and down should be given as cuf1, cuu1, and
1080       cud1.  These local cursor motions should not alter the text  they  pass
1081       over,  for  example,  you  would  not normally use `cuf1= ' because the
1082       space would erase the character moved over.
1083
1084       A very important point here is that the local cursor motions encoded in
1085       terminfo  are  undefined  at  the left and top edges of a CRT terminal.
1086       Programs should never attempt to backspace around the left edge, unless
1087       bw  is given, and never attempt to go up locally off the top.  In order
1088       to scroll text up, a program will go to the bottom left corner  of  the
1089       screen and send the ind (index) string.
1090
1091       To  scroll  text  down,  a  program  goes to the top left corner of the
1092       screen and sends the ri (reverse index) string.  The strings ind and ri
1093       are undefined when not on their respective corners of the screen.
1094
1095       Parameterized  versions  of  the  scrolling  sequences are indn and rin
1096       which have the same semantics as ind and ri except that they  take  one
1097       parameter,  and scroll that many lines.  They are also undefined except
1098       at the appropriate edge of the screen.
1099
1100       The am capability tells whether the cursor sticks at the right edge  of
1101       the  screen when text is output, but this does not necessarily apply to
1102       a cuf1 from the last column.  The only local motion  which  is  defined
1103       from  the  left  edge is if bw is given, then a cub1 from the left edge
1104       will move to the right edge of the previous row.  If bw is  not  given,
1105       the  effect  is undefined.  This is useful for drawing a box around the
1106       edge of the screen, for example.  If the terminal has switch selectable
1107       automatic  margins,  the terminfo file usually assumes that this is on;
1108       i.e., am.  If the terminal has a command which moves to the first  col‐
1109       umn  of  the next line, that command can be given as nel (newline).  It
1110       does not matter if the command clears  the  remainder  of  the  current
1111       line,  so  if the terminal has no cr and lf it may still be possible to
1112       craft a working nel out of one or both of them.
1113
1114       These capabilities suffice to describe hard-copy and “glass-tty” termi‐
1115       nals.  Thus the model 33 teletype is described as
1116
1117       33|tty33|tty|model 33 teletype,
1118            bel=^G, cols#72, cr=^M, cud1=^J, hc, ind=^J, os,
1119
1120       while the Lear Siegler ADM-3 is described as
1121
1122       adm3|3|lsi adm3,
1123            am, bel=^G, clear=^Z, cols#80, cr=^M, cub1=^H, cud1=^J,
1124            ind=^J, lines#24,
1125
1126   Parameterized Strings
1127       Cursor  addressing and other strings requiring parameters in the termi‐
1128       nal are described by a parameterized string capability, with  printf(3)
1129       like  escapes  %x  in  it.  For example, to address the cursor, the cup
1130       capability is given, using  two  parameters:  the  row  and  column  to
1131       address  to.  (Rows and columns are numbered from zero and refer to the
1132       physical screen visible to the user, not to any unseen memory.)  If the
1133       terminal  has  memory relative cursor addressing, that can be indicated
1134       by mrcup.
1135
1136       The parameter mechanism uses a stack and special % codes to  manipulate
1137       it.   Typically  a  sequence  will  push one of the parameters onto the
1138       stack and then print it in some format.  Print (e.g., "%d") is  a  spe‐
1139       cial case.  Other operations, including "%t" pop their operand from the
1140       stack.  It is noted that more complex operations are  often  necessary,
1141       e.g., in the sgr string.
1142
1143       The % encodings have the following meanings:
1144
1145       %%   outputs `%'
1146
1147       %[[:]flags][width[.precision]][doxXs]
1148            as  in  printf, flags are [-+#] and space.  Use a `:' to allow the
1149            next character to be a `-' flag, avoiding interpreting "%-" as  an
1150            operator.
1151
1152       %c   print pop() like %c in printf
1153
1154       %s   print pop() like %s in printf
1155
1156       %p[1-9]
1157            push i'th parameter
1158
1159       %P[a-z]
1160            set dynamic variable [a-z] to pop()
1161
1162       %g[a-z]
1163            get dynamic variable [a-z] and push it
1164
1165       %P[A-Z]
1166            set static variable [a-z] to pop()
1167
1168       %g[A-Z]
1169            get static variable [a-z] and push it
1170
1171            The  terms  "static"  and "dynamic" are misleading.  Historically,
1172            these are simply two different sets of variables, whose values are
1173            not reset between calls to tparm.  However, that fact is not docu‐
1174            mented in other implementations.  Relying  on  it  will  adversely
1175            impact portability to other implementations.

1184       %+ %- %* %/ %m
1185            arithmetic (%m is mod): push(pop() op pop())
1186
1187       %& %| %^
1188            bit operations (AND, OR and exclusive-OR): push(pop() op pop())
1189
1190       %= %> %<
1191            logical operations: push(pop() op pop())
1192
1193       %A, %O
1194            logical AND and OR operations (for conditionals)
1195
1196       %! %~
1197            unary operations (logical and bit complement): push(op pop())
1198
1199       %i   add 1 to first two parameters (for ANSI terminals)
1200
1201       %? expr %t thenpart %e elsepart %;
1202            This forms an if-then-else.  The %e elsepart is optional.  Usually
1203            the %? expr part pushes a value onto the stack,  and  %t  pops  it
1204            from  the  stack,  testing if it is nonzero (true).  If it is zero
1205            (false), control passes to the %e (else) part.
1206
1207            It is possible to form else-if's a la Algol 68:
1208            %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e %;
1209
1210            where ci are conditions, bi are bodies.
1211
1212            Use the -f option of tic or infocmp to see the  structure  of  if-
1213            the-else's.   Some strings, e.g., sgr can be very complicated when
1214            written on one line.  The -f option splits the string  into  lines
1215            with the parts indented.
1216
1217       Binary  operations  are  in postfix form with the operands in the usual
1218       order.  That is, to get x-5 one would use "%gx%{5}%-".  %P and %g vari‐
1219       ables are persistent across escape-string evaluations.
1220
1221       Consider  the HP2645, which, to get to row 3 and column 12, needs to be
1222       sent \E&a12c03Y padded for 6 milliseconds.  Note that the order of  the
1223       rows  and  columns  is  inverted  here, and that the row and column are
1224       printed   as   two   digits.     Thus    its    cup    capability    is
1225       “cup=6\E&%p2%2dc%p1%2dY”.
1226
1227       The  Microterm ACT-IV needs the current row and column sent preceded by
1228       a  ^T,  with  the  row   and   column   simply   encoded   in   binary,
1229       “cup=^T%p1%c%p2%c”.   Terminals  which  use  “%c”  need  to  be able to
1230       backspace the cursor (cub1), and to move the cursor up one line on  the
1231       screen  (cuu1).   This  is  necessary  because it is not always safe to
1232       transmit \n ^D and \r, as the system may change or discard them.   (The
1233       library  routines  dealing with terminfo set tty modes so that tabs are
1234       never expanded, so \t is safe to send.  This turns out to be  essential
1235       for the Ann Arbor 4080.)
1236
1237       A  final example is the LSI ADM-3a, which uses row and column offset by
1238       a blank character, thus “cup=\E=%p1%' '%+%c%p2%' '%+%c”.  After sending
1239       `\E=',  this  pushes  the first parameter, pushes the ASCII value for a
1240       space (32), adds them (pushing the sum on the stack in place of the two
1241       previous  values) and outputs that value as a character.  Then the same
1242       is done for the second parameter.  More complex arithmetic is  possible
1243       using the stack.
1244
1245   Cursor Motions
1246       If  the  terminal has a fast way to home the cursor (to very upper left
1247       corner of screen) then this can be given as home; similarly a fast  way
1248       of  getting  to the lower left-hand corner can be given as ll; this may
1249       involve going up with cuu1 from the home position, but a program should
1250       never do this itself (unless ll does) because it can make no assumption
1251       about the effect of moving up from the home position.   Note  that  the
1252       home  position is the same as addressing to (0,0): to the top left cor‐
1253       ner of the screen, not of memory.  (Thus, the \EH sequence on HP termi‐
1254       nals cannot be used for home.)
1255
1256       If the terminal has row or column absolute cursor addressing, these can
1257       be given as single  parameter  capabilities  hpa  (horizontal  position
1258       absolute)  and  vpa  (vertical position absolute).  Sometimes these are
1259       shorter than the more general  two  parameter  sequence  (as  with  the
1260       hp2645)  and can be used in preference to cup.  If there are parameter‐
1261       ized local motions (e.g., move n spaces to  the  right)  these  can  be
1262       given  as cud, cub, cuf, and cuu with a single parameter indicating how
1263       many spaces to move.  These are primarily useful if the  terminal  does
1264       not have cup, such as the TEKTRONIX 4025.
1265
1266       If  the  terminal  needs to be in a special mode when running a program
1267       that uses these capabilities, the codes to enter and exit this mode can
1268       be  given as smcup and rmcup.  This arises, for example, from terminals
1269       like the Concept with more than one page of memory.   If  the  terminal
1270       has only memory relative cursor addressing and not screen relative cur‐
1271       sor addressing, a one screen-sized window must be fixed into the termi‐
1272       nal  for cursor addressing to work properly.  This is also used for the
1273       TEKTRONIX 4025, where smcup sets the command character to  be  the  one
1274       used  by  terminfo.   If the smcup sequence will not restore the screen
1275       after an rmcup sequence is output (to the  state  prior  to  outputting
1276       rmcup), specify nrrmc.
1277
1278   Area Clears
1279       If  the  terminal can clear from the current position to the end of the
1280       line, leaving the cursor where it is, this should be given as  el.   If
1281       the  terminal  can  clear from the beginning of the line to the current
1282       position inclusive, leaving the cursor where  it  is,  this  should  be
1283       given  as  el1.  If the terminal can clear from the current position to
1284       the end of the display, then this should be given as ed.   Ed  is  only
1285       defined from the first column of a line.  (Thus, it can be simulated by
1286       a request to delete a large number of lines, if a true ed is not avail‐
1287       able.)
1288
1289   Insert/delete line and vertical motions
1290       If  the  terminal  can  open a new blank line before the line where the
1291       cursor is, this should be given as il1; this  is  done  only  from  the
1292       first  position  of  a  line.  The cursor must then appear on the newly
1293       blank line.  If the terminal can delete the line which  the  cursor  is
1294       on,  then this should be given as dl1; this is done only from the first
1295       position on the line to be deleted.  Versions of il1 and dl1 which take
1296       a single parameter and insert or delete that many lines can be given as
1297       il and dl.
1298
1299       If the terminal has a settable scrolling region (like  the  vt100)  the
1300       command  to  set  this  can be described with the csr capability, which
1301       takes two parameters: the top and bottom lines of the scrolling region.
1302       The cursor position is, alas, undefined after using this command.
1303
1304       It  is possible to get the effect of insert or delete line using csr on
1305       a properly chosen region; the sc and rc (save and restore cursor)  com‐
1306       mands  may  be  useful for ensuring that your synthesized insert/delete
1307       string does not move the cursor.  (Note that  the  ncurses(3X)  library
1308       does   this   synthesis   automatically,   so   you  need  not  compose
1309       insert/delete strings for an entry with csr).
1310
1311       Yet another way to construct insert and delete might be to use a combi‐
1312       nation  of  index  with the memory-lock feature found on some terminals
1313       (like the HP-700/90 series, which however also has insert/delete).
1314
1315       Inserting lines at the top or bottom of the screen  can  also  be  done
1316       using  ri  or  ind on many terminals without a true insert/delete line,
1317       and is often faster even on terminals with those features.
1318
1319       The boolean non_dest_scroll_region should be set if each scrolling win‐
1320       dow  is  effectively a view port on a screen-sized canvas.  To test for
1321       this capability, create a scrolling region in the middle of the screen,
1322       write  something  to the bottom line, move the cursor to the top of the
1323       region, and do ri followed by dl1 or ind.  If the data scrolled off the
1324       bottom  of  the  region  by  the  ri re-appears, then scrolling is non-
1325       destructive.  System V and XSI Curses expect that ind,  ri,  indn,  and
1326       rin  will  simulate destructive scrolling; their documentation cautions
1327       you not to define csr unless this is true.  This curses  implementation
1328       is more liberal and will do explicit erases after scrolling if ndstr is
1329       defined.
1330
1331       If the terminal has the ability to define a window as part  of  memory,
1332       which  all  commands  affect,  it  should be given as the parameterized
1333       string wind.  The four parameters are the starting and ending lines  in
1334       memory and the starting and ending columns in memory, in that order.
1335
1336       If the terminal can retain display memory above, then the da capability
1337       should be given; if display memory  can  be  retained  below,  then  db
1338       should  be given.  These indicate that deleting a line or scrolling may
1339       bring non-blank lines up from below or that scrolling back with ri  may
1340       bring down non-blank lines.
1341
1342   Insert/Delete Character
1343       There  are  two  basic  kinds  of intelligent terminals with respect to
1344       insert/delete character which can be  described  using  terminfo.   The
1345       most  common insert/delete character operations affect only the charac‐
1346       ters on the current line and shift characters off the end of  the  line
1347       rigidly.  Other terminals, such as the Concept 100 and the Perkin Elmer
1348       Owl, make a distinction between typed and untyped blanks on the screen,
1349       shifting  upon  an  insert  or  delete  only to an untyped blank on the
1350       screen which is either eliminated, or expanded to two  untyped  blanks.
1351       You  can determine the kind of terminal you have by clearing the screen
1352       and then typing text separated by cursor  motions.   Type  “abc    def”
1353       using  local  cursor  motions  (not  spaces)  between the “abc” and the
1354       “def”.  Then position the cursor before the “abc” and put the  terminal
1355       in  insert  mode.   If typing characters causes the rest of the line to
1356       shift rigidly and characters to fall off the end,  then  your  terminal
1357       does  not  distinguish  between  blanks  and untyped positions.  If the
1358       “abc” shifts over to the “def” which then move together around the  end
1359       of  the current line and onto the next as you insert, you have the sec‐
1360       ond type of terminal, and should give the capability in,  which  stands
1361       for  “insert  null”.  While these are two logically separate attributes
1362       (one line versus multi-line  insert  mode,  and  special  treatment  of
1363       untyped  spaces)  we have seen no terminals whose insert mode cannot be
1364       described with the single attribute.
1365
1366       Terminfo can describe both terminals which have  an  insert  mode,  and
1367       terminals  which send a simple sequence to open a blank position on the
1368       current line.  Give as smir the sequence to get into insert mode.  Give
1369       as  rmir  the  sequence  to  leave  insert  mode.  Now give as ich1 any
1370       sequence needed to be sent just before  sending  the  character  to  be
1371       inserted.   Most  terminals with a true insert mode will not give ich1;
1372       terminals which send a sequence to open a screen position  should  give
1373       it here.
1374
1375       If  your  terminal has both, insert mode is usually preferable to ich1.
1376       Technically, you should not give  both  unless  the  terminal  actually
1377       requires  both to be used in combination.  Accordingly, some non-curses
1378       applications get confused if both are present; the symptom  is  doubled
1379       characters  in  an  update using insert.  This requirement is now rare;
1380       most ich sequences do not require previous smir, and most  smir  insert
1381       modes  do  not  require ich1 before each character.  Therefore, the new
1382       curses actually assumes this is the case and uses either  rmir/smir  or
1383       ich/ich1  as appropriate (but not both).  If you have to write an entry
1384       to be used under new curses for a terminal old  enough  to  need  both,
1385       include the rmir/smir sequences in ich1.
1386
1387       If post insert padding is needed, give this as a number of milliseconds
1388       in ip (a string option).  Any other sequence which may need to be  sent
1389       after an insert of a single character may also be given in ip.  If your
1390       terminal needs both to be placed into an `insert mode'  and  a  special
1391       code  to  precede each inserted character, then both smir/rmir and ich1
1392       can be given, and both will be used.   The  ich  capability,  with  one
1393       parameter, n, will repeat the effects of ich1 n times.
1394
1395       If  padding  is  necessary between characters typed while not in insert
1396       mode, give this as a number of milliseconds padding in rmp.
1397
1398       It is occasionally necessary to move around while  in  insert  mode  to
1399       delete  characters  on the same line (e.g., if there is a tab after the
1400       insertion position).  If your terminal allows motion  while  in  insert
1401       mode  you  can  give  the  capability mir to speed up inserting in this
1402       case.  Omitting mir will affect only speed.   Some  terminals  (notably
1403       Datamedia's)  must  not  have  mir because of the way their insert mode
1404       works.
1405
1406       Finally, you can specify dch1 to delete a single  character,  dch  with
1407       one  parameter,  n,  to  delete n characters, and delete mode by giving
1408       smdc and rmdc to enter and exit delete  mode  (any  mode  the  terminal
1409       needs to be placed in for dch1 to work).
1410
1411       A  command  to  erase  n  characters (equivalent to outputting n blanks
1412       without moving the cursor) can be given as ech with one parameter.
1413
1414   Highlighting, Underlining, and Visible Bells
1415       If your terminal has one or more kinds of display attributes, these can
1416       be  represented  in  a number of different ways.  You should choose one
1417       display form as standout mode,  representing  a  good,  high  contrast,
1418       easy-on-the-eyes,  format  for  highlighting  error  messages and other
1419       attention getters.  (If you have a choice,  reverse  video  plus  half-
1420       bright  is  good,  or reverse video alone.)  The sequences to enter and
1421       exit standout mode are given as smso and rmso,  respectively.   If  the
1422       code  to  change  into  or  out of standout mode leaves one or even two
1423       blank spaces on the screen, as the TVI 912 and Teleray  1061  do,  then
1424       xmc should be given to tell how many spaces are left.
1425
1426       Codes to begin underlining and end underlining can be given as smul and
1427       rmul respectively.  If the terminal has a code to underline the current
1428       character  and  move  the  cursor  one  space to the right, such as the
1429       Microterm Mime, this can be given as uc.
1430
1431       Other capabilities to enter various highlighting  modes  include  blink
1432       (blinking)  bold  (bold or extra bright) dim (dim or half-bright) invis
1433       (blanking or invisible text) prot (protected) rev (reverse video)  sgr0
1434       (turn  off  all  attribute  modes) smacs (enter alternate character set
1435       mode) and rmacs (exit alternate character set mode).  Turning on any of
1436       these modes singly may or may not turn off other modes.
1437
1438       If  there  is  a  sequence to set arbitrary combinations of modes, this
1439       should be given as sgr (set attributes),  taking  9  parameters.   Each
1440       parameter  is either 0 or nonzero, as the corresponding attribute is on
1441       or off.  The 9 parameters are, in order: standout, underline,  reverse,
1442       blink,  dim,  bold,  blank,  protect, alternate character set.  Not all
1443       modes need be supported by sgr, only those for which corresponding sep‐
1444       arate attribute commands exist.
1445
1446       For example, the DEC vt220 supports most of the modes:
1447
1448 tparm parameter                attribute    escape sequence
1449
1450 none                           none         \E[0m
1451 p1                             standout     \E[0;1;7m
1452 p2                             underline    \E[0;4m
1453 p3                             reverse      \E[0;7m
1454 p4                             blink        \E[0;5m
1455 p5                             dim          not available
1456 p6                             bold         \E[0;1m
1457 p7                             invis        \E[0;8m
1458 p8                             protect      not used
1459 p9                             altcharset   ^O (off) ^N (on)
1460
1461       We  begin each escape sequence by turning off any existing modes, since
1462       there is no quick way to determine whether they are  active.   Standout
1463       is  set up to be the combination of reverse and bold.  The vt220 termi‐
1464       nal has a protect mode, though it is not commonly used in  sgr  because
1465       it  protects  characters  on  the screen from the host's erasures.  The
1466       altcharset mode also is different in  that  it  is  either  ^O  or  ^N,
1467       depending  on whether it is off or on.  If all modes are turned on, the
1468       resulting sequence is \E[0;1;4;5;7;8m^N.
1469
1470       Some sequences are common to different modes.  For example, ;7 is  out‐
1471       put  when  either  p1  or  p3  is  true, that is, if either standout or
1472       reverse modes are turned on.
1473
1474       Writing out the above sequences, along with their dependencies yields
1475

sequence when to output terminfo translation

1480;4                             if p2               %?%p2%|%t;4%;
1481;5                             if p4               %?%p4%|%t;5%;
1482;7                             if p1 or p3         %?%p1%p3%|%t;7%;
1483;8                             if p7               %?%p7%|%t;8%;
1484m                              always              m
1485^N or ^O                       if p9 ^N, else ^O   %?%p9%t^N%e^O%;
1486
1487       Putting this all together into the sgr sequence gives:
1488
1489           sgr=\E[0%?%p1%p6%|%t;1%;%?%p2%t;4%;%?%p1%p3%|%t;7%;
1490               %?%p4%t;5%;%?%p7%t;8%;m%?%p9%t\016%e\017%;,
1491
1492       Remember that if you specify sgr, you must also  specify  sgr0.   Also,
1493       some  implementations  rely on sgr being given if sgr0 is, Not all ter‐
1494       minfo entries necessarily have an sgr string, however.   Many  terminfo
1495       entries are derived from termcap entries which have no sgr string.  The
1496       only drawback to adding an sgr string is that termcap also assumes that
1497       sgr0 does not exit alternate character set mode.
1498
1499       Terminals  with  the  ``magic  cookie''  glitch  (xmc)  deposit special
1500       ``cookies'' when they receive mode-setting sequences, which affect  the
1501       display  algorithm  rather  than  having extra bits for each character.
1502       Some terminals, such as the HP 2621, automatically leave standout  mode
1503       when  they  move  to  a  new line or the cursor is addressed.  Programs
1504       using standout mode should exit standout mode before moving the  cursor
1505       or  sending a newline, unless the msgr capability, asserting that it is
1506       safe to move in standout mode, is present.
1507
1508       If the terminal has a way of flashing the screen to indicate  an  error
1509       quietly  (a  bell replacement) then this can be given as flash; it must
1510       not move the cursor.
1511
1512       If the cursor needs to be made more visible than normal when it is  not
1513       on the bottom line (to make, for example, a non-blinking underline into
1514       an easier to find block or blinking underline) give  this  sequence  as
1515       cvvis.  If there is a way to make the cursor completely invisible, give
1516       that as civis.  The capability cnorm should be given which  undoes  the
1517       effects of both of these modes.
1518
1519       If  your  terminal  correctly  generates underlined characters (with no
1520       special codes needed) even though it  does  not  overstrike,  then  you
1521       should  give  the  capability  ul.  If a character overstriking another
1522       leaves both characters on the screen, specify the  capability  os.   If
1523       overstrikes are erasable with a blank, then this should be indicated by
1524       giving eo.
1525
1526   Keypad and Function Keys
1527       If the terminal has a keypad that transmits codes  when  the  keys  are
1528       pressed,  this  information can be given.  Note that it is not possible
1529       to handle terminals where the keypad only works in local (this applies,
1530       for  example, to the unshifted HP 2621 keys).  If the keypad can be set
1531       to transmit or not transmit, give these codes as smkx and rmkx.  Other‐
1532       wise  the  keypad is assumed to always transmit.  The codes sent by the
1533       left arrow, right arrow, up arrow, down arrow, and  home  keys  can  be
1534       given  as kcub1, kcuf1, kcuu1, kcud1, and khome respectively.  If there
1535       are function keys such as f0, f1, ..., f10, the codes they send can  be
1536       given as kf0, kf1, ..., kf10.  If these keys have labels other than the
1537       default f0 through f10, the labels can be given as lf0, lf1, ..., lf10.
1538       The  codes  transmitted by certain other special keys can be given: kll
1539       (home down), kbs (backspace), ktbc (clear all tabs), kctab  (clear  the
1540       tab  stop  in  this  column),  kclr  (clear screen or erase key), kdch1
1541       (delete character), kdl1 (delete line), krmir (exit insert  mode),  kel
1542       (clear  to  end  of  line), ked (clear to end of screen), kich1 (insert
1543       character or enter insert mode), kil1 (insert line), knp  (next  page),
1544       kpp  (previous  page),  kind  (scroll  forward/down), kri (scroll back‐
1545       ward/up), khts (set a tab stop in this column).  In  addition,  if  the
1546       keypad  has  a  3 by 3 array of keys including the four arrow keys, the
1547       other five keys can be given as ka1, ka3, kb2,  kc1,  and  kc3.   These
1548       keys  are  useful  when  the  effects  of  a 3 by 3 directional pad are
1549       needed.
1550
1551       Strings to program function keys can be given as pfkey, pfloc, and pfx.
1552       A  string to program screen labels should be specified as pln.  Each of
1553       these strings takes two parameters: the function key number to  program
1554       (from 0 to 10) and the string to program it with.  Function key numbers
1555       out of this range may program undefined keys in  a  terminal  dependent
1556       manner.   The  difference between the capabilities is that pfkey causes
1557       pressing the given key to be the same as  the  user  typing  the  given
1558       string;  pfloc  causes  the  string  to  be executed by the terminal in
1559       local; and pfx causes the string to be transmitted to the computer.
1560
1561       The capabilities nlab, lw and lh  define  the  number  of  programmable
1562       screen  labels  and  their  width and height.  If there are commands to
1563       turn the labels on and off, give them in smln and rmln.  smln  is  nor‐
1564       mally  output  after  one  or  more pln sequences to make sure that the
1565       change becomes visible.
1566
1567   Tabs and Initialization
1568       If the terminal has hardware tabs, the command to advance to  the  next
1569       tab  stop  can be given as ht (usually control I).  A ``back-tab'' com‐
1570       mand which moves leftward to the preceding tab stop  can  be  given  as
1571       cbt.  By convention, if the teletype modes indicate that tabs are being
1572       expanded by the computer rather than being sent to the  terminal,  pro‐
1573       grams should not use ht or cbt even if they are present, since the user
1574       may not have the tab stops properly set.  If the terminal has  hardware
1575       tabs  which  are initially set every n spaces when the terminal is pow‐
1576       ered up, the numeric parameter it is given, showing the number of  spa‐
1577       ces  the tabs are set to.  This is normally used by the tset command to
1578       determine whether to set the  mode  for  hardware  tab  expansion,  and
1579       whether  to  set the tab stops.  If the terminal has tab stops that can
1580       be saved in non-volatile memory, the terminfo  description  can  assume
1581       that they are properly set.
1582
1583       Other  capabilities  include  is1, is2, and is3, initialization strings
1584       for the terminal, iprog, the path name of a program to be run  to  ini‐
1585       tialize  the  terminal, and if, the name of a file containing long ini‐
1586       tialization strings.  These strings are expected to  set  the  terminal
1587       into  modes consistent with the rest of the terminfo description.  They
1588       are normally sent to the terminal, by the init option of the tput  pro‐
1589       gram,  each time the user logs in.  They will be printed in the follow‐
1590       ing order:
1591
1592              run the program
1593                     iprog
1594
1595              output is1 is2
1596
1597              set the margins using
1598                     mgc, smgl and smgr
1599
1600              set tabs using
1601                     tbc and hts
1602
1603              print the file
1604                     if
1605
1606              and finally
1607                     output is3.
1608
1609       Most initialization is done with is2.  Special terminal  modes  can  be
1610       set  up  without duplicating strings by putting the common sequences in
1611       is2 and special cases in is1 and is3.
1612
1613       A set of sequences that does a harder  reset  from  a  totally  unknown
1614       state can be given as rs1, rs2, rf and rs3, analogous to is1 , is2 , if
1615       and is3 respectively.  These strings are output by the  reset  program,
1616       which is used when the terminal gets into a wedged state.  Commands are
1617       normally placed in rs1, rs2 rs3 and rf only if  they  produce  annoying
1618       effects on the screen and are not necessary when logging in.  For exam‐
1619       ple, the command to set the vt100 into 80-column mode would normally be
1620       part  of is2, but it causes an annoying glitch of the screen and is not
1621       normally needed since the terminal is  usually  already  in  80  column
1622       mode.
1623
1624       The  reset  program  writes  strings including iprog, etc., in the same
1625       order as the init program, using rs1, etc., instead of  is1,  etc.   If
1626       any  of  rs1, rs2, rs3, or rf reset capability strings are missing, the
1627       reset program falls back upon the corresponding initialization capabil‐
1628       ity string.
1629
1630       If  there are commands to set and clear tab stops, they can be given as
1631       tbc (clear all tab stops) and hts (set a tab stop in the current column
1632       of  every  row).   If a more complex sequence is needed to set the tabs
1633       than can be described by this, the sequence can be placed in is2 or if.
1634
1635   Delays and Padding
1636       Many older and slower terminals do not support either XON/XOFF  or  DTR
1637       handshaking,  including  hard copy terminals and some very archaic CRTs
1638       (including, for example, DEC VT100s).  These may require padding  char‐
1639       acters after certain cursor motions and screen changes.
1640
1641       If the terminal uses xon/xoff handshaking for flow control (that is, it
1642       automatically emits ^S back to the host  when  its  input  buffers  are
1643       close  to  full),  set xon.  This capability suppresses the emission of
1644       padding.  You can also set it for memory-mapped console devices  effec‐
1645       tively  that  do  not  have  a speed limit.  Padding information should
1646       still be included so that routines can make better decisions about rel‐
1647       ative costs, but actual pad characters will not be transmitted.
1648
1649       If pb (padding baud rate) is given, padding is suppressed at baud rates
1650       below the value of pb.  If the entry has no  padding  baud  rate,  then
1651       whether padding is emitted or not is completely controlled by xon.
1652
1653       If  the  terminal requires other than a null (zero) character as a pad,
1654       then this can be given as pad.  Only the first  character  of  the  pad
1655       string is used.
1656
1657   Status Lines
1658       Some  terminals  have an extra `status line' which is not normally used
1659       by software (and thus not counted in the terminal's lines capability).
1660
1661       The simplest case is a status line which is cursor-addressable but  not
1662       part of the main scrolling region on the screen; the Heathkit H19 has a
1663       status line of this kind, as would  a  24-line  VT100  with  a  23-line
1664       scrolling region set up on initialization.  This situation is indicated
1665       by the hs capability.
1666
1667       Some terminals with status lines need special sequences to  access  the
1668       status  line.  These may be expressed as a string with single parameter
1669       tsl which takes the cursor to a given zero-origin column on the  status
1670       line.   The  capability fsl must return to the main-screen cursor posi‐
1671       tions before the last tsl.  You may need to embed the string values  of
1672       sc  (save  cursor) and rc (restore cursor) in tsl and fsl to accomplish
1673       this.
1674
1675       The status line is normally assumed to be the same width as  the  width
1676       of  the  terminal.   If  this  is  untrue,  you can specify it with the
1677       numeric capability wsl.
1678
1679       A command to erase or blank the status line may be specified as dsl.
1680
1681       The boolean capability eslok specifies  that  escape  sequences,  tabs,
1682       etc., work ordinarily in the status line.
1683
1684       The  ncurses implementation does not yet use any of these capabilities.
1685       They are documented here in case they ever become important.
1686
1687   Line Graphics
1688       Many terminals have alternate character sets useful for  forms-drawing.
1689       Terminfo  and  curses  build in support for the drawing characters sup‐
1690       ported by the VT100, with some characters from the AT&T  4410v1  added.
1691       This alternate character set may be specified by the acsc capability.
1692

1727
1728       The  best  way to define a new device's graphics set is to add a column
1729       to a copy of this table for your terminal, giving the  character  which
1730       (when  emitted  between  smacs/rmacs  switches) will be rendered as the
1731       corresponding graphic.  Then read off the VT100/your terminal character
1732       pairs right to left in sequence; these become the ACSC string.
1733
1734   Color Handling
1735       Most  color  terminals  are either `Tektronix-like' or `HP-like'.  Tek‐
1736       tronix-like terminals have a predefined set of N colors (where  N  usu‐
1737       ally  8),  and can set character-cell foreground and background charac‐
1738       ters independently, mixing them into N *  N  color-pairs.   On  HP-like
1739       terminals,  the  use must set each color pair up separately (foreground
1740       and background are not independently settable).  Up  to  M  color-pairs
1741       may be set up from 2*M different colors.  ANSI-compatible terminals are
1742       Tektronix-like.
1743
1744       Some basic color capabilities are independent of the color method.  The
1745       numeric  capabilities  colors  and pairs specify the maximum numbers of
1746       colors and color-pairs that can be displayed  simultaneously.   The  op
1747       (original pair) string resets foreground and background colors to their
1748       default values for the terminal.  The oc string resets  all  colors  or
1749       color-pairs  to  their default values for the terminal.  Some terminals
1750       (including many PC terminal emulators) erase screen areas with the cur‐
1751       rent  background  color  rather  than  the power-up default background;
1752       these should have the boolean capability bce.
1753
1754       To change the current foreground or background color  on  a  Tektronix-
1755       type  terminal,  use  setaf  (set  ANSI foreground) and setab (set ANSI
1756       background) or setf (set foreground) and setb (set background).   These
1757       take one parameter, the color number.  The SVr4 documentation describes
1758       only setaf/setab; the XPG4 draft says that "If  the  terminal  supports
1759       ANSI  escape sequences to set background and foreground, they should be
1760       coded as setaf and setab, respectively.  If the terminal supports other
1761       escape sequences to set background and foreground, they should be coded
1762       as setf and setb, respectively.  The vidputs() function and the refresh
1763       functions use setaf and setab if they are defined."
1764
1765       The  setaf/setab and setf/setb capabilities take a single numeric argu‐
1766       ment each.  Argument values 0-7 of setaf/setab are portably defined  as
1767       follows  (the  middle  column  is the symbolic #define available in the
1768       header for the curses or ncurses libraries).  The terminal hardware  is
1769       free to map these as it likes, but the RGB values indicate normal loca‐
1770       tions in color space.
1771
1772                    Color       #define       Value       RGB
1773                    black     COLOR_BLACK       0     0, 0, 0
1774                    red       COLOR_RED         1     max,0,0
1775                    green     COLOR_GREEN       2     0,max,0
1776                    yellow    COLOR_YELLOW      3     max,max,0
1777                    blue      COLOR_BLUE        4     0,0,max
1778                    magenta   COLOR_MAGENTA     5     max,0,max
1779                    cyan      COLOR_CYAN        6     0,max,max
1780                    white     COLOR_WHITE       7     max,max,max
1781
1782       The argument values of setf/setb historically correspond to a different
1783       mapping, i.e.,
1784
1785                    Color       #define       Value       RGB
1786                    black     COLOR_BLACK       0     0, 0, 0
1787                    blue      COLOR_BLUE        1     0,0,max
1788                    green     COLOR_GREEN       2     0,max,0
1789                    cyan      COLOR_CYAN        3     0,max,max
1790                    red       COLOR_RED         4     max,0,0
1791                    magenta   COLOR_MAGENTA     5     max,0,max
1792                    yellow    COLOR_YELLOW      6     max,max,0
1793                    white     COLOR_WHITE       7     max,max,max
1794       It is important to not confuse the two sets of color capabilities; oth‐
1795       erwise red/blue will be interchanged on the display.
1796
1797       On an HP-like terminal, use scp with a color-pair number  parameter  to
1798       set which color pair is current.
1799
1800       On  a  Tektronix-like  terminal,  the  capability ccc may be present to
1801       indicate that colors can be modified.  If so, the initc capability will
1802       take  a  color  number (0 to colors - 1)and three more parameters which
1803       describe the color.  These three parameters  default  to  being  inter‐
1804       preted as RGB (Red, Green, Blue) values.  If the boolean capability hls
1805       is present, they  are  instead  as  HLS  (Hue,  Lightness,  Saturation)
1806       indices.  The ranges are terminal-dependent.
1807
1808       On  an  HP-like  terminal,  initp  may give a capability for changing a
1809       color-pair value.  It will take seven parameters; a  color-pair  number
1810       (0  to  max_pairs - 1), and two triples describing first background and
1811       then foreground colors.  These parameters must be (Red, Green, Blue) or
1812       (Hue, Lightness, Saturation) depending on hls.
1813
1814       On  some color terminals, colors collide with highlights.  You can reg‐
1815       ister these collisions with the ncv capability.  This is a bit-mask  of
1816       attributes  not to be used when colors are enabled.  The correspondence
1817       with the attributes understood by curses is as follows:
1818
1819                    Attribute                   Bit    Decimal
1820                    A_STANDOUT                  0     1
1821                    A_UNDERLINE                 1     2
1822                    A_REVERSE                   2     4
1823                    A_BLINK                     3     8
1824                    A_DIM                       4     16
1825                    A_BOLD                      5     32
1826                    A_INVIS                     6     64
1827                    A_PROTECT                   7     128
1828                    A_ALTCHARSET                8     256
1829
1830       For example, on many IBM PC consoles, the underline attribute  collides
1831       with  the  foreground  color  blue  and is not available in color mode.
1832       These should have an ncv capability of 2.
1833
1834       SVr4 curses does nothing with ncv, ncurses recognizes it and  optimizes
1835       the output in favor of colors.
1836
1837   Miscellaneous
1838       If  the  terminal requires other than a null (zero) character as a pad,
1839       then this can be given as pad.  Only the first  character  of  the  pad
1840       string is used.  If the terminal does not have a pad character, specify
1841       npc.  Note that ncurses implements the termcap-compatible PC  variable;
1842       though  the  application  may  set this value to something other than a
1843       null, ncurses will test npc first and use napms if the terminal has  no
1844       pad character.
1845
1846       If  the terminal can move up or down half a line, this can be indicated
1847       with hu (half-line up) and hd (half-line down).  This is primarily use‐
1848       ful for superscripts and subscripts on hard-copy terminals.  If a hard-
1849       copy terminal can eject to the next page (form feed), give this  as  ff
1850       (usually control L).
1851
1852       If  there  is  a  command to repeat a given character a given number of
1853       times (to save time transmitting a large number  of  identical  charac‐
1854       ters)  this  can  be  indicated with the parameterized string rep.  The
1855       first parameter is the character to be repeated and the second  is  the
1856       number of times to repeat it.  Thus, tparm(repeat_char, 'x', 10) is the
1857       same as `xxxxxxxxxx'.
1858
1859       If the terminal has a settable command character, such as the TEKTRONIX
1860       4025,  this can be indicated with cmdch.  A prototype command character
1861       is chosen which is used in all capabilities.  This character  is  given
1862       in  the  cmdch  capability to identify it.  The following convention is
1863       supported on some UNIX systems: The environment is to be searched for a
1864       CC  variable,  and if found, all occurrences of the prototype character
1865       are replaced with the character in the environment variable.
1866
1867       Terminal descriptions that do not represent a specific  kind  of  known
1868       terminal,  such  as  switch, dialup, patch, and network, should include
1869       the gn (generic) capability so that programs can complain that they  do
1870       not  know how to talk to the terminal.  (This capability does not apply
1871       to virtual terminal descriptions for which  the  escape  sequences  are
1872       known.)
1873
1874       If  the  terminal has a ``meta key'' which acts as a shift key, setting
1875       the 8th bit of any character transmitted, this fact  can  be  indicated
1876       with  km.   Otherwise,  software will assume that the 8th bit is parity
1877       and it will usually be cleared.  If strings exist to turn  this  ``meta
1878       mode'' on and off, they can be given as smm and rmm.
1879
1880       If the terminal has more lines of memory than will fit on the screen at
1881       once, the number of lines of memory can be indicated with lm.  A  value
1882       of lm#0 indicates that the number of lines is not fixed, but that there
1883       is still more memory than fits on the screen.
1884
1885       If the terminal is one of those supported by the UNIX virtual  terminal
1886       protocol, the terminal number can be given as vt.
1887
1888       Media  copy strings which control an auxiliary printer connected to the
1889       terminal can be given as mc0: print the contents of  the  screen,  mc4:
1890       turn  off  the printer, and mc5: turn on the printer.  When the printer
1891       is on, all text sent to the terminal will be sent to the  printer.   It
1892       is  undefined whether the text is also displayed on the terminal screen
1893       when the printer is on.  A variation  mc5p  takes  one  parameter,  and
1894       leaves the printer on for as many characters as the value of the param‐
1895       eter, then turns the printer off.  The parameter should not exceed 255.
1896       All  text,  including mc4, is transparently passed to the printer while
1897       an mc5p is in effect.
1898
1899   Glitches and Braindamage
1900       Hazeltine terminals, which do not allow `~' characters to be  displayed
1901       should indicate hz.
1902
1903       Terminals  which  ignore a line-feed immediately after an am wrap, such
1904       as the Concept and vt100, should indicate xenl.
1905
1906       If el is required to get rid of standout  (instead  of  merely  writing
1907       normal text on top of it), xhp should be given.
1908
1909       Teleray terminals, where tabs turn all characters moved over to blanks,
1910       should indicate xt (destructive tabs).  Note: the  variable  indicating
1911       this  is  now  `dest_tabs_magic_smso';  in  older versions, it was tel‐
1912       eray_glitch.  This glitch is also taken to mean that it is not possible
1913       to  position  the  cursor  on  top of a ``magic cookie'', that to erase
1914       standout mode it is instead necessary to use delete  and  insert  line.
1915       The ncurses implementation ignores this glitch.
1916
1917       The  Beehive Superbee, which is unable to correctly transmit the escape
1918       or control C characters, has xsb, indicating that the f1  key  is  used
1919       for  escape  and  f2  for control C.  (Only certain Superbees have this
1920       problem, depending on the ROM.)  Note that in older terminfo  versions,
1921       this capability was called `beehive_glitch'; it is now `no_esc_ctl_c'.
1922
1923       Other  specific terminal problems may be corrected by adding more capa‐
1924       bilities of the form xx.
1925
1926   Similar Terminals
1927       If there are two very similar  terminals,  one  (the  variant)  can  be
1928       defined  as  being  just  like the other (the base) with certain excep‐
1929       tions.  In the definition of the variant, the string capability use can
1930       be  given  with  the name of the base terminal.  The capabilities given
1931       before use override those in the base type named by use.  If there  are
1932       multiple  use capabilities, they are merged in reverse order.  That is,
1933       the rightmost use reference is processed first, then  the  one  to  its
1934       left,  and  so forth.  Capabilities given explicitly in the entry over‐
1935       ride those brought in by use references.
1936
1937       A capability can be canceled by placing xx@ to the left of the use ref‐
1938       erence  that  imports it, where xx is the capability.  For example, the
1939       entry
1940
1941                                2621-nl, smkx@, rmkx@, use=2621,
1942
1943       defines a 2621-nl that does not have the smkx or rmkx capabilities, and
1944       hence  does  not  turn  on the function key labels when in visual mode.
1945       This is useful for different modes for a  terminal,  or  for  different
1946       user preferences.
1947
1948   Pitfalls of Long Entries
1949       Long  terminfo  entries are unlikely to be a problem; to date, no entry
1950       has even approached terminfo's 4096-byte string-table maximum.   Unfor‐
1951       tunately,  the  termcap translations are much more strictly limited (to
1952       1023 bytes), thus termcap translations of  long  terminfo  entries  can
1953       cause problems.
1954
1955       The  man  pages for 4.3BSD and older versions of tgetent() instruct the
1956       user to allocate a 1024-byte buffer for the termcap entry.   The  entry
1957       gets  null-terminated by the termcap library, so that makes the maximum
1958       safe length for a termcap entry 1k-1 (1023) bytes.  Depending  on  what
1959       the  application  and the termcap library being used does, and where in
1960       the termcap file the terminal type that tgetent() is searching for  is,
1961       several bad things can happen.
1962
1963       Some  termcap libraries print a warning message or exit if they find an
1964       entry that's longer than 1023 bytes; others do not; others truncate the
1965       entries  to  1023  bytes.  Some application programs allocate more than
1966       the recommended 1K for the termcap entry; others do not.
1967
1968       Each termcap entry has two important sizes associated with  it:  before
1969       "tc"  expansion, and after "tc" expansion.  "tc" is the capability that
1970       tacks on another termcap entry to the end of the current one, to add on
1971       its capabilities.  If a termcap entry does not use the "tc" capability,
1972       then of course the two lengths are the same.
1973
1974       The "before tc expansion" length is the most important one, because  it
1975       affects  more than just users of that particular terminal.  This is the
1976       length of the entry as it exists in /etc/termcap, minus the  backslash-
1977       newline pairs, which tgetent() strips out while reading it.  Some term‐
1978       cap libraries strip off the final newline, too (GNU termcap does  not).
1979       Now suppose:
1980
1981       *    a termcap entry before expansion is more than 1023 bytes long,
1982
1983       *    and the application has only allocated a 1k buffer,
1984
1985       *    and the termcap library (like the one in BSD/OS 1.1 and GNU) reads
1986            the whole entry into the buffer, no matter what its length, to see
1987            if it is the entry it wants,
1988
1989       *    and  tgetent() is searching for a terminal type that either is the
1990            long entry, appears in the termcap file after the long  entry,  or
1991            does  not  appear  in  the  file  at all (so that tgetent() has to
1992            search the whole termcap file).
1993
1994       Then tgetent() will overwrite memory, perhaps its stack,  and  probably
1995       core  dump the program.  Programs like telnet are particularly vulnera‐
1996       ble; modern telnets pass along values like the terminal type  automati‐
1997       cally.   The  results are almost as undesirable with a termcap library,
1998       like SunOS 4.1.3 and Ultrix 4.4, that prints warning messages  when  it
1999       reads  an  overly  long  termcap entry.  If a termcap library truncates
2000       long entries, like OSF/1 3.0, it is  immune  to  dying  here  but  will
2001       return incorrect data for the terminal.
2002
2003       The  "after  tc  expansion"  length  will  have a similar effect to the
2004       above, but only for people who actually set TERM to that terminal type,
2005       since  tgetent() only does "tc" expansion once it is found the terminal
2006       type it was looking for, not while searching.
2007
2008       In summary, a termcap entry that is longer than 1023 bytes  can  cause,
2009       on  various  combinations of termcap libraries and applications, a core
2010       dump, warnings, or incorrect operation.  If it is too long even  before
2011       "tc"  expansion,  it will have this effect even for users of some other
2012       terminal types and users whose TERM variable does not  have  a  termcap
2013       entry.
2014
2015       When  in  -C (translate to termcap) mode, the ncurses implementation of
2016       tic(1M) issues warning messages when the pre-tc  length  of  a  termcap
2017       translation  is  too  long.  The -c (check) option also checks resolved
2018       (after tc expansion) lengths.
2019
2020   Binary Compatibility
2021       It is not wise to count  on  portability  of  binary  terminfo  entries
2022       between  commercial  UNIX  versions.   The problem is that there are at
2023       least two versions of terminfo (under HP-UX  and  AIX)  which  diverged
2024       from  System  V terminfo after SVr1, and have added extension capabili‐
2025       ties to the string table that (in the binary format) collide with  Sys‐
2026       tem V and XSI Curses extensions.
2027

EXTENSIONS

2029       Some  SVr4  curses  implementations,  and  all previous to SVr4, do not
2030       interpret the %A and %O operators in parameter strings.
2031
2032       SVr4/XPG4 do not specify whether msgr licenses  movement  while  in  an
2033       alternate-character-set  mode  (such modes may, among other things, map
2034       CR and NL to characters  that  do  not  trigger  local  motions).   The
2035       ncurses  implementation  ignores  msgr in ALTCHARSET mode.  This raises
2036       the possibility that an XPG4 implementation making the opposite  inter‐
2037       pretation  may  need  terminfo  entries  made  for ncurses to have msgr
2038       turned off.
2039
2040       The ncurses library handles insert-character and insert-character modes
2041       in  a  slightly  non-standard way to get better update efficiency.  See
2042       the Insert/Delete Character subsection above.
2043
2044       The parameter substitutions for set_clock  and  display_clock  are  not
2045       documented  in  SVr4 or the XSI Curses standard.  They are deduced from
2046       the documentation for the AT&T 505 terminal.
2047
2048       Be careful assigning the kmous capability.  The ncurses wants to inter‐
2049       pret  it  as  KEY_MOUSE,  for use by terminals and emulators like xterm
2050       that  can  return  mouse-tracking  information  in  the  keyboard-input
2051       stream.
2052
2053       Different  commercial  ports  of  terminfo and curses support different
2054       subsets of the XSI Curses standard and (in some cases) different exten‐
2055       sion sets.  Here is a summary, accurate as of October 1995:
2056
