terminfo



SYNOPSIS

       /usr/share/terminfo/*/*


DESCRIPTION

       Terminfo  is  a  data  base  describing terminals, used by
       screen-oriented programs  such  as  nvi(1),  rogue(1)  and
       libraries  such  as ncurses(3NCURSES).  Terminfo describes
       terminals by giving a set of capabilities which they have,
       by  specifying  how  to  perform screen operations, and by
       specifying   padding   requirements   and   initialization
       sequences.

       Entries in terminfo consist of a sequence of `,' separated
       fields (embedded commas may be escaped with a backslash or
       notated  as \054).  White space after the `,' separator is
       ignored.  The first entry  for  each  terminal  gives  the
       names  which  are known for the terminal, separated by `|'
       characters.  The first  name  given  is  the  most  common
       abbreviation  for the terminal, the last name given should
       be a long name fully identifying  the  terminal,  and  all
       others  are  understood as synonyms for the terminal name.
       All names but the last should be in lower case and contain
       no  blanks;  the last name may well contain upper case and
       blanks for readability.

       Terminal names (except for the last, verbose entry) should
       be chosen using the following conventions.  The particular
       piece of hardware making up the  terminal  should  have  a
       root  name, thus ``hp2621''.  This name should not contain
       hyphens.  Modes that the hardware can be in, or user pref­
       erences,  should  be indicated by appending a hyphen and a
       mode suffix.  Thus, a vt100 in 132 column  mode  would  be
       vt100-w.  The following suffixes should be used where pos­
       sible:

      Suffix                  Meaning                   Example
      -nn      Number of lines on the screen            aaa-60
      -np      Number of pages of memory                c100-4p
      -am      With automargins (usually the default)   vt100-am
      -m       Mono mode; suppress color                ansi-m
      -mc      Magic cookie; spaces when highlighting   wy30-mc
      -na      No arrow keys (leave them in local)      c100-na
      -nam     Without automatic margins                vt100-nam
      -nl      No status line                           att4415-nl
      -ns      No status line                           hp2626-ns
      -rv      Reverse video                            c100-rv
      -s       Enable status line                       vt100-s
      -vb      Use visible bell instead of beep         wy370-vb
      -w       Wide mode (> 80 columns, usually 132)    vt100-w

       For more on terminal naming conventions, see  the  term(7)
       manual page.
       Semantics are also intended to match those of the specifi­
       cation.

       The termcap code is the old termcap capability name  (some
       capabilities are new, and have names which termcap did not
       originate).

       Capability names have no hard length limit, but an  infor­
       mal  limit  of  5 characters has been adopted to keep them
       short and to allow the tabs in the  source  file  Caps  to
       line up nicely.

       Finally,  the  description  field  attempts  to convey the
       semantics of the capability.  You may find some  codes  in
       the description field:

       (P)    indicates that padding may be specified

       #[1-9] in  the description field indicates that the string
              is passed through tparm with parms as given (#i).

       (P*)   indicates that padding may vary  in  proportion  to
              the number of lines affected

       (#i)   indicates the ith parameter.

       These are the boolean capabilities:

       Entries may continue onto multiple lines by placing  white
       space  at  the  beginning  of  each line except the first.
       Comments may be included on lines  beginning  with  ``#''.
       Capabilities in terminfo are of three types: Boolean capa­
       bilities which indicate that the terminal has some partic­
       ular  feature, numeric capabilities giving the size of the
       terminal or the size  of  particular  delays,  and  string
       capabilities,  which  give a sequence which can be used to
       perform particular terminal operations.

   Types of Capabilities
       All capabilities have names.  For instance, the fact  that
       ANSI-standard  terminals  have automatic margins (i.e., an
       automatic return and line-feed when the end of a  line  is
       A  number  of  escape sequences are provided in the string
       valued capabilities for easy encoding of characters there.
       Both  \E  and  \e map to an ESCAPE character, ^x maps to a
       control-x for any appropriate x, and the sequences  \n  \l
       \r  \t  \b  \f  \s give a newline, line-feed, return, tab,
       backspace, form-feed, and space.  Other escapes include \^
       for  ^, \\ for \, \, for comma, \: for :, and \0 for null.
       (\0 will produce \200, which does not terminate  a  string
       but behaves as a null character on most terminals, provid­
       ing CS7 is specified.  See stty(1).)  Finally,  characters
       may be given as three octal digits after a \.

       A  delay  in  milliseconds may appear anywhere in a string
       capability, enclosed in $<..> brackets, as in  el=\EK$<5>,
       and  padding  characters  are supplied by tputs to provide
       this delay.  The delay must be a number with at  most  one
       decimal place of precision; it may be followed by suffixes
       `*' or '/' or both.  A  `*'  indicates  that  the  padding
       required  is  proportional to the number of lines affected
       by the  operation,  and  the  amount  given  is  the  per-
       affected-unit  padding  required.   (In the case of insert
       character,  the  factor  is  still  the  number  of  lines
       affected.)   Normally,  padding  is advisory if the device
       has the xon capability; it is used  for  cost  computation
       but  does not trigger delays.  A `/' suffix indicates that
       the padding is mandatory and forces a delay of  the  given
       number  of  milliseconds  even on devices for which xon is
       present to indicate flow control.

       Sometimes individual capabilities must be  commented  out.
       To  do this, put a period before the capability name.  For
       example, see the second ind in the example above.

   Fetching Compiled Descriptions
       If the environment variable TERMINFO is set, it is  inter­
       preted  as the pathname of a directory containing the com­
       piled description you are working on.  Only that directory
       is searched.

       If  TERMINFO  is  not set, the ncurses version of the ter­
       minfo reader code  will  instead  look  in  the  directory
       $HOME/.terminfo  for  a compiled description.  If it fails
       to find one  there,  and  the  environment  variable  TER­
       MINFO_DIRS  is set, it will interpret the contents of that
       variable as a list of colon- separated directories  to  be
       searched  (an  empty  entry is interpreted as a command to
       search /usr/share/terminfo).  If no description  is  found
       in  any of the TERMINFO_DIRS directories, the fetch fails.

       If neither TERMINFO nor TERMINFO_DIRS  is  set,  the  last
       place   tried  will  be  the  system  terminfo  directory,
       very unusual terminal may expose deficiencies in the abil­
       ity  of  the  terminfo  file to describe it or bugs in the
       screen-handling code of the test program.

       To get the padding for insert line right (if the  terminal
       manufacturer did not document it) a severe test is to edit
       a large file at 9600 baud, delete 16 or so lines from  the
       middle  of  the screen, then hit the `u' key several times
       quickly.  If the terminal messes up, more padding is  usu­
       ally  needed.  A similar test can be used for insert char­
       acter.

   Basic Capabilities
       The number of columns on each line  for  the  terminal  is
       given  by the cols numeric capability.  If the terminal is
       a CRT, then the number of lines on the screen is given  by
       the lines capability.  If the terminal wraps around to the
       beginning of the next line when it reaches the right  mar­
       gin, then it should have the am capability.  If the termi­
       nal can clear its screen, leaving the cursor in  the  home
       position,  then this is given by the clear string capabil­
       ity.  If the terminal overstrikes (rather than clearing  a
       position  when  a character is struck over) then it should
       have the os capability.  If the  terminal  is  a  printing
       terminal,  with no soft copy unit, give it both hc and os.
       (os applies to storage scope terminals, such as  TEKTRONIX
       4010  series, as well as hard copy and APL terminals.)  If
       there is a code to move the cursor to the left edge of the
       current row, give this as cr.  (Normally this will be car­
       riage return, control M.)  If there is a code  to  produce
       an audible signal (bell, beep, etc) give this as bel.

       If  there is a code to move the cursor one position to the
       left (such as backspace) that capability should  be  given
       as  cub1.   Similarly, codes to move to the right, up, and
       down should be given as cuf1, cuu1, and cud1.  These local
       cursor  motions  should not alter the text they pass over,
       for example, you would not normally use  `cuf1= '  because
       the space would erase the character moved over.

       A  very  important  point  here  is  that the local cursor
       motions encoded in terminfo are undefined at the left  and
       top  edges  of  a  CRT  terminal.   Programs  should never
       attempt to backspace around the left edge,  unless  bw  is
       given, and never attempt to go up locally off the top.  In
       order to scroll text up, a program will go to  the  bottom
       left corner of the screen and send the ind (index) string.

       To scroll text down, a program goes to the top left corner
       of  the  screen  and  sends the ri (reverse index) string.
       The strings ind and ri are undefined  when  not  on  their
       given,  the effect is undefined.  This is useful for draw­
       ing a box around the edge of the screen, for example.   If
       the  terminal has switch selectable automatic margins, the
       terminfo file usually assumes that this is on;  i.e.,  am.
       If  the  terminal  has  a command which moves to the first
       column of the next line, that command can be given as  nel
       (newline).   It  does not matter if the command clears the
       remainder of the current line, so if the terminal  has  no
       cr  and lf it may still be possible to craft a working nel
       out of one or both of them.

       These  capabilities  suffice  to  describe  hard-copy  and
       "glass-tty"  terminals.   Thus  the  model  33 teletype is
       described as

     33|tty33|tty|model 33 teletype,
     bel=^G, cols#72, cr=^M, cud1=^J, hc, ind=^J, os,

       while the Lear Siegler ADM-3 is described as

     adm3|3|lsi adm3,
     am, bel=^G, clear=^Z, cols#80, cr=^M, cub1=^H, cud1=^J,
     ind=^J, lines#24,

   Parameterized Strings
       Cursor addressing and other strings  requiring  parameters
       in  the  terminal  are described by a parameterized string
       capability, with printf(3S) like escapes %x  in  it.   For
       example,  to  address  the  cursor,  the cup capability is
       given, using two parameters: the row and column to address
       to.  (Rows and columns are numbered from zero and refer to
       the physical screen visible to the user, not to any unseen
       memory.)   If  the  terminal  has  memory  relative cursor
       addressing, that can be indicated by mrcup.

       The parameter mechanism uses a stack and special  %  codes
       to  manipulate  it.  Typically a sequence will push one of
       the parameters onto the stack and then print  it  in  some
       format.   Print  (e.g.,  "%d")  is  a special case.  Other
       operations, including "%t"  pop  their  operand  from  the
       stack.  It is noted that more complex operations are often
       necessary, e.g., in the sgr string.

       The % encodings have the following meanings:

       %%   outputs `%'

       %[[:]flags][width[.precision]][doxXs]
            as in printf, flags are [-+#] and space

            set static variable [a-z] to pop()

       %g[A-Z]
            get static variable [a-z] and push it

            The terms  "static"  and  "dynamic"  are  misleading.
            Historically,  these are simply two different sets of
            variables, whose values are not reset  between  calls
            to  tparm.   However,  that fact is not documented in
            other implementations.  Relying on it will  adversely
            impact portability to other implementations.

       %= %> %<
            logical operations: push(pop() op pop())

            possible a la Algol 68:
            %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e %;
            ci are conditions, bi are bodies.

       Binary operations are in postfix form with the operands in
       the usual order.  That  is,  to  get  x-5  one  would  use
       "%gx%{5}%-".   %P  and  %g variables are persistent across
       escape-string evaluations.

       Consider the HP2645, which, to get to row 3 and column 12,
       needs  to  be  sent  \E&a12c03Y padded for 6 milliseconds.
       Note that the order of the rows and  columns  is  inverted
       here,  and that the row and column are printed as two dig­
       its.  Thus its cup capability is "cup=6\E&%p2%2dc%p1%2dY".
       '%+%c%p2%' '%+%c".  After sending `\E=', this  pushes  the
       first  parameter, pushes the ASCII value for a space (32),
       adds them (pushing the sum on the stack in  place  of  the
       two  previous  values) and outputs that value as a charac­
       ter.  Then the same is  done  for  the  second  parameter.
       More complex arithmetic is possible using the stack.

   Cursor Motions
       If the terminal has a fast way to home the cursor (to very
       upper left corner of screen) then this  can  be  given  as
       home;  similarly  a fast way of getting to the lower left-
       hand corner can be given as ll; this may involve going  up
       with  cuu1  from  the  home position, but a program should
       never do this itself (unless ll does) because it can  make
       no  assumption about the effect of moving up from the home
       position.  Note that the home  position  is  the  same  as
       addressing to (0,0): to the top left corner of the screen,
       not of memory.  (Thus, the \EH sequence  on  HP  terminals
       cannot be used for home.)

       If the terminal has row or column absolute cursor address­
       ing, these can be given as single  parameter  capabilities
       hpa (horizontal position absolute) and vpa (vertical posi­
       tion absolute).  Sometimes these are shorter than the more
       general  two  parameter  sequence (as with the hp2645) and
       can be used in preference to cup.  If there are parameter­
       ized  local  motions  (e.g.,  move  n spaces to the right)
       these can be given as cud, cub, cuf, and cuu with a single
       parameter  indicating  how many spaces to move.  These are
       primarily useful if the terminal does not have  cup,  such
       as the TEKTRONIX 4025.

       If the terminal needs to be in a special mode when running
       a program that uses these capabilities, the codes to enter
       and  exit this mode can be given as smcup and rmcup.  This
       arises, for example, from terminals like the Concept  with
       more  than  one  page of memory.  If the terminal has only
       memory relative cursor addressing and not screen  relative
       cursor addressing, a one screen-sized window must be fixed
       into the terminal for cursor addressing to work  properly.
       This is also used for the TEKTRONIX 4025, where smcup sets
       the command character to be the one used by terminfo.   If
       the  smcup  sequence  will not restore the screen after an
       rmcup sequence is output (to the state prior to outputting
       rmcup), specify nrrmc.

   Area Clears
       If the terminal can clear from the current position to the
       end of the line, leaving the  cursor  where  it  is,  this
       should be given as el.  If the terminal can clear from the
       can delete the line which the  cursor  is  on,  then  this
       should  be  given as dl1; this is done only from the first
       position on the line to be deleted.  Versions of  il1  and
       dl1  which  take  a  single parameter and insert or delete
       that many lines can be given as il and dl.

       If the terminal has a settable scrolling region (like  the
       vt100)  the  command to set this can be described with the
       csr capability, which takes two parameters:  the  top  and
       bottom lines of the scrolling region.  The cursor position
       is, alas, undefined after using this command.

       It is possible to get the effect of insert or delete  line
       using csr on a properly chosen region; the sc and rc (save
       and restore cursor) commands may be  useful  for  ensuring
       that  your  synthesized insert/delete string does not move
       the cursor.  (Note that the ncurses(3NCURSES) library does
       this  synthesis  automatically,  so  you  need not compose
       insert/delete strings for an entry with csr).

       Yet another way to construct insert and delete might be to
       use  a  combination  of index with the memory-lock feature
       found on some terminals (like the HP-700/90 series,  which
       however also has insert/delete).

       Inserting  lines  at  the  top or bottom of the screen can
       also be done using ri or ind on many terminals  without  a
       true  insert/delete line, and is often faster even on ter­
       minals with those features.

       The boolean non_dest_scroll_region should be set  if  each
       scrolling  window  is effectively a view port on a screen-
       sized canvas.  To  test  for  this  capability,  create  a
       scrolling  region in the middle of the screen, write some­
       thing to the bottom line, move the cursor to  the  top  of
       the region, and do ri followed by dl1 or ind.  If the data
       scrolled off the bottom  of  the  region  by  the  ri  re-
       appears,  then scrolling is non-destructive.  System V and
       XSI Curses expect that ind, ri, indn, and rin  will  simu­
       late  destructive  scrolling; their documentation cautions
       you not to define csr unless this is  true.   This  curses
       implementation is more liberal and will do explicit erases
       after scrolling if ndstr is defined.

       If the terminal has the ability to define a window as part
       of  memory,  which all commands affect, it should be given
       as the parameterized string wind.  The four parameters are
       the  starting  and ending lines in memory and the starting
       and ending columns in memory, in that order.

       If the terminal can retain display memory above, then  the
       da  capability  should  be given; if display memory can be
       blanks on the screen, shifting upon an  insert  or  delete
       only  to  an  untyped  blank on the screen which is either
       eliminated, or expanded to two untyped  blanks.   You  can
       determine  the  kind  of terminal you have by clearing the
       screen and then typing text separated by  cursor  motions.
       Type  "abc    def" using local cursor motions (not spaces)
       between the "abc" and the "def".  Then position the cursor
       before  the "abc" and put the terminal in insert mode.  If
       typing characters causes the rest of  the  line  to  shift
       rigidly and characters to fall off the end, then your ter­
       minal does not  distinguish  between  blanks  and  untyped
       positions.   If  the  "abc" shifts over to the "def" which
       then move together around the end of the current line  and
       onto  the  next as you insert, you have the second type of
       terminal, and should give the capability in, which  stands
       for "insert null".  While these are two logically separate
       attributes (one line versus multi-line  insert  mode,  and
       special  treatment of untyped spaces) we have seen no ter­
       minals whose insert mode cannot be described with the sin­
       gle attribute.

       Terminfo  can describe both terminals which have an insert
       mode, and terminals which send a simple sequence to open a
       blank  position  on  the  current  line.  Give as smir the
       sequence to get  into  insert  mode.   Give  as  rmir  the
       sequence  to  leave  insert  mode.   Now  give as ich1 any
       sequence needed to be sent just before sending the charac­
       ter  to  be  inserted.   Most terminals with a true insert
       mode will not give ich1; terminals which send  a  sequence
       to open a screen position should give it here.

       If  your terminal has both, insert mode is usually prefer­
       able to ich1.   Technically,  you  should  not  give  both
       unless  the  terminal actually requires both to be used in
       combination.  Accordingly,  some  non-curses  applications
       get  confused  if both are present; the symptom is doubled
       characters in an update using insert.  This requirement is
       now rare; most ich sequences do not require previous smir,
       and most smir insert modes do not require ich1 before each
       character.   Therefore,  the  new  curses actually assumes
       this is the case and uses either rmir/smir or ich/ich1  as
       appropriate (but not both).  If you have to write an entry
       to be used under new curses for a terminal old  enough  to
       need both, include the rmir/smir sequences in ich1.

       If post insert padding is needed, give this as a number of
       milliseconds in ip (a string option).  Any other  sequence
       which  may  need  to  be  sent after an insert of a single
       character may also be given in ip.  If your terminal needs
       both to be placed into an `insert mode' and a special code
       to precede each inserted character,  then  both  smir/rmir
       and  ich1  can  be  given, and both will be used.  The ich
       their insert mode works.

       Finally, you can specify dch1 to delete a  single  charac­
       ter,  dch  with  one parameter, n, to delete n characters,
       and delete mode by giving smdc and rmdc to enter and  exit
       delete  mode  (any mode the terminal needs to be placed in
       for dch1 to work).

       A command to erase n characters (equivalent to  outputting
       n  blanks  without  moving the cursor) can be given as ech
       with one parameter.

   Highlighting, Underlining, and Visible Bells
       If  your  terminal  has  one  or  more  kinds  of  display
       attributes,  these  can be represented in a number of dif­
       ferent ways.  You should choose one display form as stand­
       out mode, representing a good, high contrast, easy-on-the-
       eyes, format for highlighting  error  messages  and  other
       attention  getters.   (If you have a choice, reverse video
       plus half-bright is good, or reverse  video  alone.)   The
       sequences  to  enter  and  exit standout mode are given as
       smso and rmso, respectively.  If the code to  change  into
       or  out  of  standout  mode  leaves  one or even two blank
       spaces on the screen, as the TVI 912 and Teleray 1061  do,
       then xmc should be given to tell how many spaces are left.

       Codes to begin underlining  and  end  underlining  can  be
       given  as smul and rmul respectively.  If the terminal has
       a code to underline the current  character  and  move  the
       cursor one space to the right, such as the Microterm Mime,
       this can be given as uc.

       Other capabilities to  enter  various  highlighting  modes
       include  blink  (blinking) bold (bold or extra bright) dim
       (dim or half-bright) invis (blanking  or  invisible  text)
       prot  (protected)  rev  (reverse video) sgr0 (turn off all
       attribute modes)  smacs  (enter  alternate  character  set
       mode)  and  rmacs  (exit  alternate  character  set mode).
       Turning on any of these modes singly may or may  not  turn
       off other modes.

       If  there  is  a sequence to set arbitrary combinations of
       modes, this should be given as sgr (set attributes),  tak­
       ing  9 parameters.  Each parameter is either 0 or nonzero,
       as the corresponding attribute is on or off.  The 9 param­
       eters  are, in order: standout, underline, reverse, blink,
       dim, bold, blank, protect, alternate character  set.   Not
       all  modes  need be supported by sgr, only those for which
       corresponding separate attribute commands exist.

       For example, the DEC vt220 supports most of the modes:

       We begin each escape sequence by turning off any  existing
       modes,  since  there  is no quick way to determine whether
       they are active.  Standout is set up to be the combination
       of  reverse  and  bold.   The vt220 terminal has a protect
       mode, though it is not commonly used  in  sgr  because  it
       protects  characters  on  the  screen from the host's era­
       sures.  The altcharset mode also is different in  that  it
       is  either ^O or ^N, depending on whether it is off or on.
       If all modes are turned  on,  the  resulting  sequence  is
       \E[0;1;4;5;7;8m^N.

       Some  sequences  are common to different modes.  For exam­
       ple, ;7 is output when either p1 or p3 is true,  that  is,
       if either standout or reverse modes are turned on.

       Writing  out  the above sequences, along with their depen­
       dencies yields

         sequence    when to output     terminfo translation

         \E[0       always              \E[0
         ;1         if p1 or p6         %?%p1%p6%|%t;1%;
         ;4         if p2               %?%p2%|%t;4%;
         ;5         if p4               %?%p4%|%t;5%;
         ;7         if p1 or p3         %?%p1%p3%|%t;7%;
         ;8         if p7               %?%p7%|%t;8%;
         m          always              m
         ^N or ^O   if p9 ^N, else ^O   %?%p9%t^N%e^O%;

       Putting this all together into the sgr sequence gives:

           sgr=\E[0%?%p1%p6%|%t;1%;%?%p2%t;4%;%?%p1%p3%|%t;7%;
               %?%p4%t;5%;%?%p7%t;8%;m%?%p9%t\016%e\017%;,

       Remember that if you specify sgr, you  must  also  specify
       sgr0.

       Terminals  with  the ``magic cookie'' glitch (xmc) deposit
       special  ``cookies''  when   they   receive   mode-setting
       sequences,  which affect the display algorithm rather than
       having extra bits for  each  character.   Some  terminals,
       such  as  the  HP  2621, automatically leave standout mode
       when they move to a new line or the cursor  is  addressed.
       Programs  using  standout  mode  should exit standout mode
       before moving the cursor or sending a newline, unless  the
       msgr  capability,  asserting  that  it  is safe to move in
       standout mode, is present.

       If the terminal has a way of flashing the screen to  indi­
       cate  an  error quietly (a bell replacement) then this can
       be given as flash; it must not move the cursor.
       erasable  with  a  blank, then this should be indicated by
       giving eo.

   Keypad and Function Keys
       If the terminal has a keypad that transmits codes when the
       keys  are  pressed,  this  information can be given.  Note
       that it is not possible to handle terminals where the key­
       pad only works in local (this applies, for example, to the
       unshifted HP 2621 keys).  If the  keypad  can  be  set  to
       transmit  or  not  transmit,  give these codes as smkx and
       rmkx.  Otherwise the keypad is assumed to always transmit.
       The  codes  sent by the left arrow, right arrow, up arrow,
       down arrow, and home keys can be given  as  kcub1,  kcuf1,
       kcuu1,  kcud1, and khome respectively.  If there are func­
       tion keys such as f0, f1, ..., f10, the  codes  they  send
       can  be  given as kf0, kf1, ..., kf10.  If these keys have
       labels other than the default f0 through f10,  the  labels
       can  be given as lf0, lf1, ..., lf10.  The codes transmit­
       ted by certain other special keys can be given: kll  (home
       down),  kbs  (backspace),  ktbc  (clear  all  tabs), kctab
       (clear the tab stop in this column), kclr (clear screen or
       erase  key), kdch1 (delete character), kdl1 (delete line),
       krmir (exit insert mode), kel (clear to end of line),  ked
       (clear to end of screen), kich1 (insert character or enter
       insert mode), kil1 (insert line),  knp  (next  page),  kpp
       (previous  page),  kind (scroll forward/down), kri (scroll
       backward/up), khts (set a tab stop in  this  column).   In
       addition, if the keypad has a 3 by 3 array of keys includ­
       ing the four arrow keys, the other five keys can be  given
       as  ka1,  ka3,  kb2,  kc1, and kc3.  These keys are useful
       when the effects of a 3 by 3 directional pad are needed.

       Strings to program function keys can be  given  as  pfkey,
       pfloc,  and pfx.  A string to program screen labels should
       be specified as pln.  Each  of  these  strings  takes  two
       parameters:  the function key number to program (from 0 to
       10) and the string to program it with.  Function key  num­
       bers  out  of  this  range may program undefined keys in a
       terminal dependent manner.   The  difference  between  the
       capabilities  is  that pfkey causes pressing the given key
       to be the same as the user typing the given string;  pfloc
       causes the string to be executed by the terminal in local;
       and pfx causes the string to be transmitted  to  the  com­
       puter.

       The capabilities nlab, lw and lh define the number of pro­
       grammable screen labels and their width  and  height.   If
       there  are  commands  to  turn the labels on and off, give
       them in smln and rmln.  smln is normally output after  one
       or more pln sequences to make sure that the change becomes
       visible.
       spaces  the tabs are set to.  This is normally used by the
       tset command to determine whether  to  set  the  mode  for
       hardware  tab expansion, and whether to set the tab stops.
       If the terminal has tab stops that can be  saved  in  non-
       volatile  memory, the terminfo description can assume that
       they are properly set.

       Other capabilities include is1, is2, and is3,  initializa­
       tion  strings  for the terminal, iprog, the path name of a
       program to be run to initialize the terminal, and if,  the
       name  of  a  file  containing long initialization strings.
       These strings are expected to set the terminal into  modes
       consistent  with  the  rest  of  the terminfo description.
       They are normally sent to the terminal, by the init option
       of  the  tput  program,  each time the user logs in.  They
       will be printed in the following order:  run  the  program
       iprog;  output  is1;  is2; set the margins using mgc, smgl
       and smgr; set tabs using tbc and hts; print the  file  if;
       and finally output is3.

       Most  initialization  is  done with is2.  Special terminal
       modes can be set up without duplicating strings by putting
       the  common  sequences in is2 and special cases in is1 and
       is3.  A pair of sequences that does a harder reset from  a
       totally  unknown  state  can  be analogously given as rs1,
       rs2, rf, and rs3, analogous to is2 and if.  These  strings
       are  output  by  the reset program, which is used when the
       terminal gets into a wedged state.  Commands are  normally
       placed  in rs1, rs2 rs3 and rf only if they produce annoy­
       ing effects on the screen and are not necessary when  log­
       ging  in.   For example, the command to set the vt100 into
       80-column mode would normally  be  part  of  is2,  but  it
       causes  an  annoying  glitch of the screen and is not nor­
       mally needed since the terminal is usually already  in  80
       column mode.

       If there are commands to set and clear tab stops, they can
       be given as tbc (clear all tab stops) and hts (set  a  tab
       stop  in the current column of every row).  If a more com­
       plex sequence is needed  to  set  the  tabs  than  can  be
       described  by  this,  the sequence can be placed in is2 or
       if.

   Delays and Padding
       Many older  and  slower  terminals  don't  support  either
       XON/XOFF or DTR handshaking, including hard copy terminals
       and some very archaic CRTs (including,  for  example,  DEC
       VT100s).   These may require padding characters after cer­
       tain cursor motions and screen changes.

       If the terminal uses xon/xoff handshaking for flow control
       (that  is, it automatically emits ^S back to the host when
       ter as a pad, then this can be given  as  pad.   Only  the
       first character of the pad string is used.

   Status Lines
       Some  terminals  have  an extra `status line' which is not
       normally used by software (and thus  not  counted  in  the
       terminal's lines capability).

       The  simplest  case  is  a  status  line  which is cursor-
       addressable but not part of the main scrolling  region  on
       the  screen;  the  Heathkit  H19 has a status line of this
       kind, as would a 24-line VT100 with  a  23-line  scrolling
       region  set up on initialization.  This situation is indi­
       cated by the hs capability.

       Some terminals with status lines need special sequences to
       access  the  status  line.   These  may  be expressed as a
       string with single parameter tsl which takes the cursor to
       a  given zero-origin column on the status line.  The capa­
       bility fsl must return to the main-screen cursor positions
       before  the  last  tsl.   You may need to embed the string
       values of sc (save cursor) and rc (restore cursor) in  tsl
       and fsl to accomplish this.

       The  status  line is normally assumed to be the same width
       as the width of the terminal.  If this is untrue, you  can
       specify it with the numeric capability wsl.

       A  command to erase or blank the status line may be speci­
       fied as dsl.

       The  boolean  capability  eslok  specifies   that   escape
       sequences, tabs, etc., work ordinarily in the status line.

       The ncurses implementation does not yet use any  of  these
       capabilities.   They are documented here in case they ever
       become important.

   Line Graphics
       Many terminals have alternate character  sets  useful  for
       forms-drawing.   Terminfo  and curses build in support for
       the drawing characters supported by the VT100,  with  some
       characters  from  the  AT&T  4410v1 added.  This alternate
       character set may be specified by the acsc capability.

       The best way to define a new device's graphics set  is  to
       add  a  column  to a copy of this table for your terminal,
       giving  the  character   which   (when   emitted   between
       smacs/rmacs  switches) will be rendered as the correspond­
       ing graphic.  Then read off the VT100/your terminal  char­
       acter  pairs  right  to left in sequence; these become the
       ACSC string.

   Color Handling
       Most color terminals are either `Tektronix-like'  or  `HP-
       like'.   Tektronix-like terminals have a predefined set of
       N colors (where N usually 8), and can  set  character-cell
       foreground and background characters independently, mixing
       them into N * N color-pairs.  On  HP-like  terminals,  the
       use must set each color pair up separately (foreground and
       background are  not  independently  settable).   Up  to  M
       color-pairs  may  be  set  up  from  2*M different colors.
       ANSI-compatible terminals are Tektronix-like.

       Some basic color capabilities are independent of the color
       method.  The numeric capabilities colors and pairs specify
       the maximum numbers of colors and color-pairs that can  be
       displayed  simultaneously.   The op (original pair) string
       resets foreground and background colors to  their  default
       values  for the terminal.  The oc string resets all colors
       or color-pairs to their default values for  the  terminal.
       Some  terminals  (including  many  PC  terminal emulators)
       erase screen  areas  with  the  current  background  color
       rather  than the power-up default background; these should
       have the boolean capability bce.

       To change the current foreground or background color on  a
       Tektronix-type  terminal,  use setaf (set ANSI foreground)
       and setab (set ANSI background) or setf  (set  foreground)
       symbolic #define available in the header for the curses or
       ncurses libraries).  The terminal hardware is free to  map
       these  as  it  likes,  but  the RGB values indicate normal
       locations in color space.

             Color       #define       Value       RGB
             black     COLOR_BLACK       0     0, 0, 0
             red       COLOR_RED         1     max,0,0
             green     COLOR_GREEN       2     0,max,0
             yellow    COLOR_YELLOW      3     max,max,0
             blue      COLOR_BLUE        4     0,0,max
             magenta   COLOR_MAGENTA     5     max,0,max
             cyan      COLOR_CYAN        6     0,max,max
             white     COLOR_WHITE       7     max,max,max

       The argument values of setf/setb  historically  correspond
       to a different mapping, i.e.,
             Color       #define       Value       RGB
             black     COLOR_BLACK       0     0, 0, 0
             blue      COLOR_BLUE        1     0,0,max
             green     COLOR_GREEN       2     0,max,0
             cyan      COLOR_CYAN        3     0,max,max
             red       COLOR_RED         4     max,0,0
             magenta   COLOR_MAGENTA     5     max,0,max
             yellow    COLOR_YELLOW      6     max,max,0
             white     COLOR_WHITE       7     max,max,max
       It is important to not confuse the two sets of color capa­
       bilities; otherwise red/blue will be interchanged  on  the
       display.

       On  an  HP-like terminal, use scp with a color-pair number
       parameter to set which color pair is current.

       On a Tektronix-like terminal, the capability  ccc  may  be
       present  to  indicate that colors can be modified.  If so,
       the initc capability will take a color number (0 to colors
       -  1)and  three  more parameters which describe the color.
       These three parameters default to being interpreted as RGB
       (Red,  Green, Blue) values.  If the boolean capability hls
       is present, they are instead as HLS (Hue, Lightness, Satu­
       ration) indices.  The ranges are terminal-dependent.

       On  an  HP-like  terminal, initp may give a capability for
       changing a color-pair value.  It will take  seven  parame­
       ters;  a  color-pair  number (0 to max_pairs - 1), and two
       triples describing first background  and  then  foreground
       colors.   These  parameters  must be (Red, Green, Blue) or
       (Hue, Lightness, Saturation) depending on hls.

       On some color terminals, colors collide  with  highlights.
       You can register these collisions with the ncv capability.
       This is a bit-mask of attributes not to be used when  col­

       For example,  on  many  IBM  PC  consoles,  the  underline
       attribute  collides  with the foreground color blue and is
       not available in color mode.  These  should  have  an  ncv
       capability of 2.

       SVr4  curses  does nothing with ncv, ncurses recognizes it
       and optimizes the output in favor of colors.

   Miscellaneous
       If the terminal requires other than a null (zero)  charac­
       ter  as  a  pad,  then this can be given as pad.  Only the
       first character of the pad string is used.  If the  termi­
       nal does not have a pad character, specify npc.  Note that
       ncurses implements  the  termcap-compatible  PC  variable;
       though  the  application  may  set this value to something
       other than a null, ncurses will test  npc  first  and  use
       napms if the terminal has no pad character.

       If  the terminal can move up or down half a line, this can
       be indicated with hu  (half-line  up)  and  hd  (half-line
       down).  This is primarily useful for superscripts and sub­
       scripts on hard-copy terminals.  If a  hard-copy  terminal
       can  eject  to  the next page (form feed), give this as ff
       (usually control L).

       If there is a command to repeat a given character a  given
       number  of times (to save time transmitting a large number
       of identical characters) this can be  indicated  with  the
       parameterized  string  rep.   The  first  parameter is the
       character to be repeated and the second is the  number  of
       times  to repeat it.  Thus, tparm(repeat_char, 'x', 10) is
       the same as `xxxxxxxxxx'.

       If the terminal has a settable command character, such  as
       the  TEKTRONIX  4025, this can be indicated with cmdch.  A
       prototype command character is chosen which is used in all
       capabilities.   This character is given in the cmdch capa­
       bility to identify it.  The following convention  is  sup­
       ported  on  some  UNIX  systems:  The environment is to be
       searched for a CC variable, and if found, all  occurrences
       of the prototype character are replaced with the character
       in the environment variable.

       Terminal descriptions that do  not  represent  a  specific
       kind of known terminal, such as switch, dialup, patch, and
       network, should include the  gn  (generic)  capability  so
       that  programs  can  complain that they do not know how to
       talk to the terminal.  (This capability does not apply  to
       virtual   terminal   descriptions  for  which  the  escape
       sequences are known.)
       If the terminal is one of those supported by the UNIX vir­
       tual terminal protocol, the terminal number can  be  given
       as vt.

       Media copy strings which control an auxiliary printer con­
       nected to the terminal can be given as mc0: print the con­
       tents  of  the screen, mc4: turn off the printer, and mc5:
       turn on the printer.  When the printer  is  on,  all  text
       sent  to  the terminal will be sent to the printer.  It is
       undefined whether the text is also displayed on the termi­
       nal screen when the printer is on.  A variation mc5p takes
       one parameter, and leaves the printer on for as many char­
       acters  as  the  value  of  the  parameter, then turns the
       printer off.  The parameter should not  exceed  255.   All
       text,  including  mc4,  is  transparently  passed  to  the
       printer while an mc5p is in effect.

   Glitches and Braindamage
       Hazeltine terminals, which do not allow `~' characters  to
       be displayed should indicate hz.

       Terminals which ignore a line-feed immediately after an am
       wrap, such as the Concept and vt100, should indicate xenl.

       If  el  is  required  to  get  rid of standout (instead of
       merely writing normal text on top of it),  xhp  should  be
       given.

       Teleray  terminals,  where  tabs turn all characters moved
       over to blanks, should  indicate  xt  (destructive  tabs).
       Note:    the    variable    indicating    this    is   now
       `dest_tabs_magic_smso'; in older  versions,  it  was  tel­
       eray_glitch.  This glitch is also taken to mean that it is
       not possible to position the cursor on top  of  a  ``magic
       cookie'', that to erase standout mode it is instead neces­
       sary to use delete and insert line.  The ncurses implemen­
       tation ignores this glitch.

       The  Beehive Superbee, which is unable to correctly trans­
       mit the escape or control C characters, has xsb,  indicat­
       ing  that the f1 key is used for escape and f2 for control
       C.  (Only certain Superbees have this  problem,  depending
       on  the  ROM.)  Note that in older terminfo versions, this
       capability  was  called  `beehive_glitch';   it   is   now
       `no_esc_ctl_c'.

       Other  specific  terminal  problems  may  be  corrected by
       adding more capabilities of the form xx.

   Similar Terminals
       bility.  For example, the entry

                   2621-nl, smkx@, rmkx@, use=2621,

       defines a 2621-nl that does not  have  the  smkx  or  rmkx
       capabilities,  and hence does not turn on the function key
       labels when in visual mode.  This is useful for  different
       modes for a terminal, or for different user preferences.

   Pitfalls of Long Entries
       Long  terminfo  entries  are  unlikely to be a problem; to
       date, no entry has even approached terminfo's  4K  string-
       table  maximum.   Unfortunately,  the termcap translations
       are much more  strictly  limited  (to  1K),  thus  termcap
       translations  of long terminfo entries can cause problems.

       The man pages for 4.3BSD and older versions  of  tgetent()
       instruct  the user to allocate a 1K buffer for the termcap
       entry.  The entry  gets  null-terminated  by  the  termcap
       library, so that makes the maximum safe length for a term­
       cap entry 1k-1 (1023) bytes.  Depending on what the appli­
       cation  and the termcap library being used does, and where
       in the termcap file the terminal type  that  tgetent()  is
       searching for is, several bad things can happen.

       Some  termcap libraries print a warning message or exit if
       they find an entry that's longer than 1023  bytes;  others
       don't;  others  truncate  the entries to 1023 bytes.  Some
       application programs allocate more than the recommended 1K
       for the termcap entry; others don't.

       Each termcap entry has two important sizes associated with
       it: before "tc" expansion, and after "tc" expansion.  "tc"
       is  the  capability that tacks on another termcap entry to
       the end of the current one, to add  on  its  capabilities.
       If  a  termcap entry doesn't use the "tc" capability, then
       of course the two lengths are the same.

       The "before tc expansion" length  is  the  most  important
       one,  because it affects more than just users of that par­
       ticular terminal.  This is the length of the entry  as  it
       exists in /etc/termcap, minus the backslash-newline pairs,
       which tgetent() strips out while reading it.  Some termcap
       libraries  strip  off  the final newline, too (GNU termcap
       does not).  Now suppose:

       *    a termcap entry before expansion is  more  than  1023
            bytes long,

       *    and the application has only allocated a 1k buffer,

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

       The "after tc expansion" length will have a similar effect
       to the above, but only for people who actually set TERM to
       that  terminal type, since tgetent() only does "tc" expan­
       sion once it's found the terminal type it was looking for,
       not while searching.

       In summary, a termcap entry that is longer than 1023 bytes
       can cause, on various combinations  of  termcap  libraries
       and  applications,  a  core  dump,  warnings, or incorrect
       operation.  If it's too long even before  "tc"  expansion,
       it will have this effect even for users of some other ter­
       minal types and users whose TERM variable does not have  a
       termcap entry.

       When in -C (translate to termcap) mode, the ncurses imple­
       mentation of tic(1) issues warning messages when the  pre-
       tc  length  of  a termcap translation is too long.  The -c
       (check) option also checks resolved (after  tc  expansion)
       lengths.

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


EXTENSIONS

       Some  SVr4  curses  implementations,  and  all previous to
       SVr4, don't interpret the %A and %O operators in parameter
       strings.

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

       The ncurses library handles insert-character  and  insert-
       Different  commercial ports of terminfo and curses support
       different subsets of the XSI Curses standard and (in  some
       cases) different extension sets.  Here is a summary, accu­
       rate as of October 1995:

       SVR4, Solaris, ncurses -- These support all SVr4 capabili­
       ties.

       SGI  --  Supports  the  SVr4  set,  adds  one undocumented
       extended string capability (set_pglen).

       SVr1, Ultrix -- These support a restricted subset of  ter­
       minfo  capabilities.   The booleans end with xon_xoff; the
       numerics with  width_status_line;  and  the  strings  with
       prtr_non.

       HP/UX  --  Supports  the  SVr1  subset,  plus the SVr[234]
       numerics num_labels, label_height, label_width, plus func­
       tion  keys  11  through  63, plus plab_norm, label_on, and
       label_off, plus some incompatible extensions in the string
       table.

       AIX  --  Supports  the  SVr1 subset, plus function keys 11
       through 63, plus a number  of  incompatible  string  table
       extensions.

       OSF  -- Supports both the SVr4 set and the AIX extensions.
