White space after the `,' separator is + ignored. The first entry for each terminal gives the + names which are known for the terminal, separated by `|' + characters. The first name given is the most common + abbreviation for the terminal, the last name given should + be a long name fully identifying the terminal, and all + others are understood as synonyms for the terminal name. + All names but the last should be in lower case and contain + no blanks; the last name may well contain upper case and + blanks for readability. + + Lines beginning with a `#' in the first column are treated + as comments. While comment lines are legal at any point, + the output of <STRONG>captoinfo</STRONG> and <STRONG>infotocap</STRONG> (aliases for <STRONG>tic</STRONG>) + will move comments so they occur only between entries. + + Newlines and leading tabs may be used for formatting + entries for readability. These are removed from parsed + entries. The <STRONG>infocmp</STRONG> <STRONG>-f</STRONG> option relies on this to format + if-then-else expressions: the result can be read by <STRONG>tic</STRONG>. + + Terminal names (except for the last, verbose entry) should + be chosen using the following conventions. The particular + piece of hardware making up the terminal should have a + root name, thus ``hp2621''. This name should not contain + hyphens. Modes that the hardware can be in, or user pref- + erences, should be indicated by appending a hyphen and a + mode suffix. Thus, a vt100 in 132 column mode would be + vt100-w. The following suffixes should be used where pos- + sible: + + + <STRONG>Suffix</STRONG> <STRONG>Meaning</STRONG> <STRONG>Example</STRONG> + -<EM>nn</EM> Number of lines on the screen aaa-60 + -<EM>n</EM>p Number of pages of memory c100-4p + -am With automargins (usually the default) vt100-am + -m Mono mode; suppress color ansi-m + -mc Magic cookie; spaces when highlighting wy30-mc + -na No arrow keys (leave them in local) c100-na + -nam Without automatic margins vt100-nam + -nl No status line att4415-nl + -ns No status line hp2626-ns + -rv Reverse video c100-rv + -s Enable status line vt100-s + + -vb Use visible bell instead of beep wy370-vb + -w Wide mode (> 80 columns, usually 132) vt100-w + + For more on terminal naming conventions, see the <STRONG>term(7)</STRONG> + manual page. + + <STRONG>Capabilities</STRONG> + The following is a complete table of the capabilities + included in a terminfo description block and available to + terminfo-using code. In each line of the table, + + The <STRONG>variable</STRONG> is the name by which the programmer (at the + terminfo level) accesses the capability. + + The <STRONG>capname</STRONG> is the short name used in the text of the + database, and is used by a person updating the database. + Whenever possible, capnames are chosen to be the same as + or similar to the ANSI X3.64-1979 standard (now superseded + by ECMA-48, which uses identical or very similar names). + Semantics are also intended to match those of the specifi- + cation. + + The termcap code is the old <STRONG>termcap</STRONG> capability name (some + capabilities are new, and have names which termcap did not + originate). + + Capability names have no hard length limit, but an infor- + mal limit of 5 characters has been adopted to keep them + short and to allow the tabs in the source file <STRONG>Caps</STRONG> to + line up nicely. + + Finally, the description field attempts to convey the + semantics of the capability. You may find some codes in + the description field: + + (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 (#<EM>i</EM>). + + (P*) indicates that padding may vary in proportion to + the number of lines affected + + (#<EM>i</EM>) indicates the <EM>i</EM>th parameter. + + + These are the boolean capabilities: + + + <STRONG>Variable</STRONG> <STRONG>Cap-</STRONG> <STRONG>TCap</STRONG> <STRONG>Description</STRONG> + <STRONG>Booleans</STRONG> <STRONG>name</STRONG> <STRONG>Code</STRONG> + auto_left_margin bw bw cub1 wraps from col- + umn 0 to last column + auto_right_margin am am terminal has auto- + matic margins + back_color_erase bce ut screen erased with + background color + can_change ccc cc terminal can re- + define existing col- + ors + ceol_standout_glitch xhp xs standout not erased + by overwriting (hp) + col_addr_glitch xhpa YA only positive motion + for hpa/mhpa caps + + + cpi_changes_res cpix YF changing character + pitch changes reso- + lution + cr_cancels_micro_mode crxm YB using cr turns off + micro mode + dest_tabs_magic_smso xt xt tabs destructive, + magic so char + (t1061) + eat_newline_glitch xenl xn newline ignored + after 80 cols (con- + cept) + erase_overstrike eo eo can erase over- + strikes with a blank + generic_type gn gn generic line type + hard_copy hc hc hardcopy terminal + hard_cursor chts HC cursor is hard to + see + has_meta_key km km Has a meta key + (i.e., sets 8th-bit) + has_print_wheel daisy YC printer needs opera- + tor to change char- + acter set + has_status_line hs hs has extra status + line + hue_lightness_saturation hls hl terminal uses only + HLS color notation + (Tektronix) + insert_null_glitch in in insert mode distin- + guishes nulls + lpi_changes_res lpix YG changing line pitch + changes resolution + memory_above da da display may be + retained above the + screen + memory_below db db display may be + retained below the + screen + move_insert_mode mir mi safe to move while + in insert mode + move_standout_mode msgr ms safe to move while + in standout mode + needs_xon_xoff nxon nx padding will not + work, xon/xoff + required + no_esc_ctlc xsb xb beehive (f1=escape, + f2=ctrl C) + no_pad_char npc NP pad character does + not exist + non_dest_scroll_region ndscr ND scrolling region is + non-destructive + non_rev_rmcup nrrmc NR smcup does not + reverse rmcup + over_strike os os terminal can over- + strike + prtr_silent mc5i 5i printer will not + echo on screen + row_addr_glitch xvpa YD only positive motion + for vpa/mvpa caps + semi_auto_right_margin sam YE printing in last + column causes cr + status_line_esc_ok eslok es escape can be used + on the status line + tilde_glitch hz hz cannot print ~'s + (hazeltine) + + + transparent_underline ul ul underline character + overstrikes + xon_xoff xon xo terminal uses + xon/xoff handshaking + + These are the numeric capabilities: + + + <STRONG>Variable</STRONG> <STRONG>Cap-</STRONG> <STRONG>TCap</STRONG> <STRONG>Description</STRONG> + <STRONG>Numeric</STRONG> <STRONG>name</STRONG> <STRONG>Code</STRONG> + columns cols co number of columns in + a line + init_tabs it it tabs initially every + # spaces + label_height lh lh rows in each label + label_width lw lw columns in each + label + lines lines li number of lines on + screen or page + lines_of_memory lm lm lines of memory if > + line. 0 means varies + magic_cookie_glitch xmc sg number of blank + characters left by + smso or rmso + max_attributes ma ma maximum combined + attributes terminal + can handle + max_colors colors Co maximum number of + colors on screen + max_pairs pairs pa maximum number of + color-pairs on the + screen + maximum_windows wnum MW maximum number of + defineable windows + no_color_video ncv NC video attributes + that cannot be used + with colors + num_labels nlab Nl number of labels on + screen + padding_baud_rate pb pb lowest baud rate + where padding needed + virtual_terminal vt vt virtual terminal + number (CB/unix) + width_status_line wsl ws number of columns in + status line + + The following numeric capabilities are present in the + SVr4.0 term structure, but are not yet documented in the + man page.

For instance, the fact that + ANSI-standard terminals have <EM>automatic</EM> <EM>margins</EM> (i.e., an + automatic return and line-feed when the end of a line is + reached) is indicated by the capability <STRONG>am</STRONG>. Hence the + description of ansi includes <STRONG>am</STRONG>. Numeric capabilities are + followed by the character `#' and then a positive value. + Thus <STRONG>cols</STRONG>, which indicates the number of columns the ter- + minal has, gives the value `80' for ansi. Values for + numeric capabilities may be specified in decimal, octal or + hexadecimal, using the C programming language conventions + (e.g., 255, 0377 and 0xff or 0xFF). + + Finally, string valued capabilities, such as <STRONG>el</STRONG> (clear to + end of line sequence) are given by the two-character code, + an `=', and then a string ending at the next following + `,'. + + A number of escape sequences are provided in the string + valued capabilities for easy encoding of characters there. + Both <STRONG>\E</STRONG> and <STRONG>\e</STRONG> map to an ESCAPE character, <STRONG>^x</STRONG> maps to a + control-x for any appropriate x, and the sequences <STRONG>\n</STRONG> <STRONG>\l</STRONG> + <STRONG>\r</STRONG> <STRONG>\t</STRONG> <STRONG>\b</STRONG> <STRONG>\f</STRONG> <STRONG>\s</STRONG> give a newline, line-feed, return, tab, + backspace, form-feed, and space. Other escapes include <STRONG>\^</STRONG> + for <STRONG>^</STRONG>, <STRONG>\\</STRONG> for <STRONG>\</STRONG>, <STRONG>\</STRONG>, for comma, <STRONG>\:</STRONG> for <STRONG>:</STRONG>, and <STRONG>\0</STRONG> for null. + (<STRONG>\0</STRONG> will produce \200, which does not terminate a string + but behaves as a null character on most terminals, provid- + ing CS7 is specified. See <STRONG><A HREF="stty.1.html">stty(1)</A></STRONG>.) Finally, characters + may be given as three octal digits after a <STRONG>\</STRONG>. + + A delay in milliseconds may appear anywhere in a string + capability, enclosed in $<..> brackets, as in <STRONG>el</STRONG>=\EK$<5>, + and padding characters are supplied by <EM>tputs</EM> 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 <EM>lines</EM> + affected.) Normally, padding is advisory if the device + has the <STRONG>xon</STRONG> 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 <STRONG>xon</STRONG> 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 <STRONG>ind</STRONG> in the example above. + + + <STRONG>Fetching</STRONG> <STRONG>Compiled</STRONG> <STRONG>Descriptions</STRONG> + 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 <STRONG>ncurses</STRONG> version of the ter- + minfo reader code will instead look in the directory + <STRONG>$HOME/.terminfo</STRONG> for a compiled description. If it fails + to find one there, and the environment variable TER- + MINFO_DIRS is set, it will interpret the contents of that + variable as a list of colon- separated directories to be + searched (an empty entry is interpreted as a command to + search <EM>/usr/share/terminfo</EM>). If no description is found + in any of the TERMINFO_DIRS directories, the fetch fails. + + If neither TERMINFO nor TERMINFO_DIRS is set, the last + place tried will be the system terminfo directory, + <EM>/usr/share/terminfo</EM>. + + (Neither the <STRONG>$HOME/.terminfo</STRONG> lookups nor TERMINFO_DIRS + extensions are supported under stock System V ter- + minfo/curses.) + + + <STRONG>Preparing</STRONG> <STRONG>Descriptions</STRONG> + We now outline how to prepare descriptions of terminals. + The most effective way to prepare a terminal description + is by imitating the description of a similar terminal in + <EM>terminfo</EM> and to build up a description gradually, using + partial descriptions with <EM>vi</EM> or some other screen-oriented + program to check that they are correct. Be aware that a + very unusual terminal may expose deficiencies in the abil- + ity of the <EM>terminfo</EM> file to describe it or bugs in the + screen-handling code of the test program. + + To get the padding for insert line right (if the terminal + manufacturer did not document it) a severe test is to edit + a large file at 9600 baud, delete 16 or so lines from the + middle of the screen, then hit the `u' key several times + quickly. If the terminal messes up, more padding is usu- + ally needed. A similar test can be used for insert char- + acter. + + + <STRONG>Basic</STRONG> <STRONG>Capabilities</STRONG> + The number of columns on each line for the terminal is + given by the <STRONG>cols</STRONG> numeric capability. If the terminal is + a CRT, then the number of lines on the screen is given by + the <STRONG>lines</STRONG> capability. If the terminal wraps around to the + beginning of the next line when it reaches the right mar- + gin, then it should have the <STRONG>am</STRONG> capability. If the termi- + nal can clear its screen, leaving the cursor in the home + position, then this is given by the <STRONG>clear</STRONG> string capabil- + ity. If the terminal overstrikes (rather than clearing a + position when a character is struck over) then it should + have the <STRONG>os</STRONG> capability. If the terminal is a printing + terminal, with no soft copy unit, give it both <STRONG>hc</STRONG> and <STRONG>os</STRONG>. + (<STRONG>os</STRONG> applies to storage scope terminals, such as TEKTRONIX + 4010 series, as well as hard copy and APL terminals.) If + there is a code to move the cursor to the left edge of the + current row, give this as <STRONG>cr</STRONG>. (Normally this will be car- + riage return, control M.) If there is a code to produce + an audible signal (bell, beep, etc) give this as <STRONG>bel</STRONG>. + + If there is a code to move the cursor one position to the + left (such as backspace) that capability should be given + as <STRONG>cub1</STRONG>. Similarly, codes to move to the right, up, and + down should be given as <STRONG>cuf1</STRONG>, <STRONG>cuu1</STRONG>, and <STRONG>cud1</STRONG>. These local + cursor motions should not alter the text they pass over, + for example, you would not normally use `<STRONG>cuf1</STRONG>= ' because + the space would erase the character moved over. + + A very important point here is that the local cursor + motions encoded in <EM>terminfo</EM> are undefined at the left and + top edges of a CRT terminal. Programs should never + attempt to backspace around the left edge, unless <STRONG>bw</STRONG> is + given, and never attempt to go up locally off the top. In + order to scroll text up, a program will go to the bottom + left corner of the screen and send the <STRONG>ind</STRONG> (index) string. + + To scroll text down, a program goes to the top left corner + of the screen and sends the <STRONG>ri</STRONG> (reverse index) string. + The strings <STRONG>ind</STRONG> and <STRONG>ri</STRONG> are undefined when not on their + respective corners of the screen. + + Parameterized versions of the scrolling sequences are <STRONG>indn</STRONG> + and <STRONG>rin</STRONG> which have the same semantics as <STRONG>ind</STRONG> and <STRONG>ri</STRONG> except + that they take one parameter, and scroll that many lines. + They are also undefined except at the appropriate edge of + the screen. + + The <STRONG>am</STRONG> capability tells whether the cursor sticks at the + right edge of the screen when text is output, but this + does not necessarily apply to a <STRONG>cuf1</STRONG> from the last column. + The only local motion which is defined from the left edge + is if <STRONG>bw</STRONG> is given, then a <STRONG>cub1</STRONG> from the left edge will + move to the right edge of the previous row. If <STRONG>bw</STRONG> is not + given, the effect is undefined. This is useful for draw- + ing a box around the edge of the screen, for example. If + the terminal has switch selectable automatic margins, the + <EM>terminfo</EM> file usually assumes that this is on; i.e., <STRONG>am</STRONG>. + If the terminal has a command which moves to the first + column of the next line, that command can be given as <STRONG>nel</STRONG> + (newline). It does not matter if the command clears the + remainder of the current line, so if the terminal has no + <STRONG>cr</STRONG> and <STRONG>lf</STRONG> it may still be possible to craft a working <STRONG>nel</STRONG> + out of one or both of them. + + These capabilities suffice to describe hard-copy and + "glass-tty" terminals. Thus the model 33 teletype is + described as + + 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, + + + <STRONG>Parameterized</STRONG> <STRONG>Strings</STRONG> + Cursor addressing and other strings requiring parameters + in the terminal are described by a parameterized string + capability, with <STRONG><A HREF="printf.3.html">printf(3)</A></STRONG> like escapes <STRONG>%x</STRONG> in it. For + example, to address the cursor, the <STRONG>cup</STRONG> 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 <STRONG>mrcup</STRONG>. + + The parameter mechanism uses a stack and special <STRONG>%</STRONG> 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 <STRONG>sgr</STRONG> string. + + The <STRONG>%</STRONG> encodings have the following meanings: + + + %% outputs `%' + + %<EM>[[</EM>:<EM>]flags][width[.precision]][</EM>doxXs<EM>]</EM> + as in <STRONG>printf</STRONG>, flags are [-+#] and space. Use a `:' + to allow the next character to be a `-' flag, avoid- + ing interpreting "%-" as an operator. + + %c print pop() like %c in <STRONG>printf</STRONG> + + %s print pop() like %s in <STRONG>printf</STRONG> + + %p[1-9] + push <EM>i</EM>'th parameter + + %P[a-z] + set dynamic variable [a-z] to pop() + + %g[a-z] + get dynamic variable [a-z] and push it + + %P[A-Z] + 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 <STRONG>tparm</STRONG>. However, that fact is not documented in + other implementations. Relying on it will adversely + impact portability to other implementations. + + %'<EM>c</EM>' char constant <EM>c</EM> + + %{<EM>nn</EM>} + integer constant <EM>nn</EM> + + %l push strlen(pop) + + %+ %- %* %/ %m + arithmetic (%m is mod): push(pop() op pop()) + + %& %| %^ + bit operations (AND, OR and exclusive-OR): push(pop() + op pop()) + + %= %> %< + logical operations: push(pop() op pop()) + + %A, %O + logical AND and OR operations (for conditionals) + + %! %~ + unary operations (logical and bit complement): + push(op pop()) + + %i add 1 to first two parameters (for ANSI terminals) + + %? <EM>expr</EM> %t <EM>thenpart</EM> %e <EM>elsepart</EM> %; + This forms an if-then-else. The %e <EM>elsepart</EM> is + optional. Usually the %? <EM>expr</EM> part pushes a value + onto the stack, and %t pops it from the stack, test- + ing if it is nonzero (true). If it is zero (false), + control passes to the %e (else) part. + + It is possible to form else-if's a la Algol 68: + %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e %; + + where ci are conditions, bi are bodies. + + Use the <STRONG>-f</STRONG> option of <STRONG>tic</STRONG> or <STRONG>infocmp</STRONG> to see the struc- + ture of if-then-else's. Some strings, e.g., <STRONG>sgr</STRONG> can + be very complicated when written on one line. The <STRONG>-f</STRONG> + option splits the string into lines with the parts + indented. + + 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 <STRONG>cup</STRONG> capability is "cup=6\E&%p2%2dc%p1%2dY". + + The Microterm ACT-IV needs the current row and column sent + preceded by a <STRONG>^T</STRONG>, with the row and column simply encoded + in binary, "cup=^T%p1%c%p2%c". Terminals which use "%c" + need to be able to backspace the cursor (<STRONG>cub1</STRONG>), and to + move the cursor up one line on the screen (<STRONG>cuu1</STRONG>). This is + necessary because it is not always safe to transmit <STRONG>\n</STRONG> <STRONG>^D</STRONG> + and <STRONG>\r</STRONG>, as the system may change or discard them. (The + library routines dealing with terminfo set tty modes so + that tabs are never expanded, so \t is safe to send. This + turns out to be essential for the Ann Arbor 4080.) + + A final example is the LSI ADM-3a, which uses row and col- + umn offset by a blank character, thus "cup=\E=%p1%' + '%+%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. + + + <STRONG>Cursor</STRONG> <STRONG>Motions</STRONG> + If the terminal has a fast way to home the cursor (to very + upper left corner of screen) then this can be given as + <STRONG>home</STRONG>; similarly a fast way of getting to the lower left- + hand corner can be given as <STRONG>ll</STRONG>; this may involve going up + with <STRONG>cuu1</STRONG> from the home position, but a program should + never do this itself (unless <STRONG>ll</STRONG> does) because it can make + no assumption about the effect of moving up from the home + position. Note that the home position is the same as + addressing to (0,0): to the top left corner of the screen, + not of memory. (Thus, the \EH sequence on HP terminals + cannot be used for <STRONG>home</STRONG>.) + + If the terminal has row or column absolute cursor address- + ing, these can be given as single parameter capabilities + <STRONG>hpa</STRONG> (horizontal position absolute) and <STRONG>vpa</STRONG> (vertical posi- + tion absolute). Sometimes these are shorter than the more + general two parameter sequence (as with the hp2645) and + can be used in preference to <STRONG>cup</STRONG>. If there are + parameterized local motions (e.g., move <EM>n</EM> spaces to the + right) these can be given as <STRONG>cud</STRONG>, <STRONG>cub</STRONG>, <STRONG>cuf</STRONG>, and <STRONG>cuu</STRONG> with a + single parameter indicating how many spaces to move. + These are primarily useful if the terminal does not have + <STRONG>cup</STRONG>, 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 <STRONG>smcup</STRONG> and <STRONG>rmcup</STRONG>. 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 <STRONG>smcup</STRONG> sets + the command character to be the one used by terminfo. If + the <STRONG>smcup</STRONG> sequence will not restore the screen after an + <STRONG>rmcup</STRONG> sequence is output (to the state prior to outputting + <STRONG>rmcup</STRONG>), specify <STRONG>nrrmc</STRONG>. + + + <STRONG>Area</STRONG> <STRONG>Clears</STRONG> + 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 <STRONG>el</STRONG>. If the terminal can clear from the + beginning of the line to the current position inclusive, + leaving the cursor where it is, this should be given as + <STRONG>el1</STRONG>. If the terminal can clear from the current position + to the end of the display, then this should be given as + <STRONG>ed</STRONG>. <STRONG>Ed</STRONG> is only defined from the first column of a line. + (Thus, it can be simulated by a request to delete a large + number of lines, if a true <STRONG>ed</STRONG> is not available.) + + + <STRONG>Insert/delete</STRONG> <STRONG>line</STRONG> <STRONG>and</STRONG> <STRONG>vertical</STRONG> <STRONG>motions</STRONG> + If the terminal can open a new blank line before the line + where the cursor is, this should be given as <STRONG>il1</STRONG>; this is + done only from the first position of a line. The cursor + must then appear on the newly blank line. If the terminal + can delete the line which the cursor is on, then this + should be given as <STRONG>dl1</STRONG>; this is done only from the first + position on the line to be deleted. Versions of <STRONG>il1</STRONG> and + <STRONG>dl1</STRONG> which take a single parameter and insert or delete + that many lines can be given as <STRONG>il</STRONG> and <STRONG>dl</STRONG>. + + If the terminal has a settable scrolling region (like the + vt100) the command to set this can be described with the + <STRONG>csr</STRONG> 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 <STRONG>csr</STRONG> on a properly chosen region; the <STRONG>sc</STRONG> and <STRONG>rc</STRONG> (save + and restore cursor) commands may be useful for ensuring + that your synthesized insert/delete string does not move + the cursor. (Note that the <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> library does this + synthesis automatically, so you need not compose + insert/delete strings for an entry with <STRONG>csr</STRONG>). + + 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 <STRONG>ri</STRONG> or <STRONG>ind</STRONG> on many terminals without a + true insert/delete line, and is often faster even on ter- + minals with those features. + + The boolean <STRONG>non_dest_scroll_region</STRONG> 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 <STRONG>ri</STRONG> followed by <STRONG>dl1</STRONG> or <STRONG>ind</STRONG>. If the data + scrolled off the bottom of the region by the <STRONG>ri</STRONG> re- + appears, then scrolling is non-destructive. System V and + XSI Curses expect that <STRONG>ind</STRONG>, <STRONG>ri</STRONG>, <STRONG>indn</STRONG>, and <STRONG>rin</STRONG> will simu- + late destructive scrolling; their documentation cautions + you not to define <STRONG>csr</STRONG> unless this is true. This <STRONG>curses</STRONG> + implementation is more liberal and will do explicit erases + after scrolling if <STRONG>ndstr</STRONG> 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 <STRONG>wind</STRONG>. 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 + <STRONG>da</STRONG> capability should be given; if display memory can be + retained below, then <STRONG>db</STRONG> should be given. These indicate + that deleting a line or scrolling may bring non-blank + lines up from below or that scrolling back with <STRONG>ri</STRONG> may + bring down non-blank lines. + + + <STRONG>Insert/Delete</STRONG> <STRONG>Character</STRONG> + There are two basic kinds of intelligent terminals with + respect to insert/delete character which can be described + using <EM>terminfo.</EM> The most common insert/delete character + operations affect only the characters on the current line + and shift characters off the end of the line rigidly. + Other terminals, such as the Concept 100 and the Perkin + Elmer Owl, make a distinction between typed and untyped + blanks on the screen, shifting upon an insert or delete + only to an untyped blank on the screen which is either + eliminated, or expanded to two untyped blanks. You can + determine the kind of terminal you have by 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 <STRONG>in</STRONG>, which stands + for "insert null". While these are two logically separate + attributes (one line versus multi-line insert mode, and + special treatment of untyped spaces) we have seen no 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 <STRONG>smir</STRONG> the + sequence to get into insert mode. Give as <STRONG>rmir</STRONG> the + sequence to leave insert mode. Now give as <STRONG>ich1</STRONG> any + sequence needed to be sent just before sending the + character to be inserted. Most terminals with a true + insert mode will not give <STRONG>ich1</STRONG>; terminals which send a + sequence to open a screen position should give it here. + + If your terminal has both, insert mode is usually prefer- + able to <STRONG>ich1</STRONG>. Technically, you should not give both + unless the terminal actually requires both to be used in + combination. Accordingly, some non-curses applications + get confused if both are present; the symptom is doubled + characters in an update using insert. This requirement is + now rare; most <STRONG>ich</STRONG> sequences do not require previous smir, + and most smir insert modes do not require <STRONG>ich1</STRONG> before each + character. Therefore, the new <STRONG>curses</STRONG> actually assumes + this is the case and uses either <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> or <STRONG>ich</STRONG>/<STRONG>ich1</STRONG> as + appropriate (but not both). If you have to write an entry + to be used under new curses for a terminal old enough to + need both, include the <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> sequences in <STRONG>ich1</STRONG>. + + If post insert padding is needed, give this as a number of + milliseconds in <STRONG>ip</STRONG> (a string option). Any other sequence + which may need to be sent after an insert of a single + character may also be given in <STRONG>ip</STRONG>. If your terminal needs + both to be placed into an `insert mode' and a special code + to precede each inserted character, then both <STRONG>smir</STRONG>/<STRONG>rmir</STRONG> + and <STRONG>ich1</STRONG> can be given, and both will be used. The <STRONG>ich</STRONG> + capability, with one parameter, <EM>n</EM>, will repeat the effects + of <STRONG>ich1</STRONG> <EM>n</EM> times. + + If padding is necessary between characters typed while not + in insert mode, give this as a number of milliseconds + padding in <STRONG>rmp</STRONG>. + + It is occasionally necessary to move around while in + insert mode to delete characters on the same line (e.g., + if there is a tab after the insertion position). If your + terminal allows motion while in insert mode you can give + the capability <STRONG>mir</STRONG> to speed up inserting in this case. + Omitting <STRONG>mir</STRONG> will affect only speed. Some terminals + (notably Datamedia's) must not have <STRONG>mir</STRONG> because of the way + their insert mode works. + + Finally, you can specify <STRONG>dch1</STRONG> to delete a single charac- + ter, <STRONG>dch</STRONG> with one parameter, <EM>n</EM>, to delete <EM>n</EM> <EM>characters,</EM> + and delete mode by giving <STRONG>smdc</STRONG> and <STRONG>rmdc</STRONG> to enter and exit + delete mode (any mode the terminal needs to be placed in + for <STRONG>dch1</STRONG> to work). + + A command to erase <EM>n</EM> characters (equivalent to outputting + <EM>n</EM> blanks without moving the cursor) can be given as <STRONG>ech</STRONG> + with one parameter. + + + <STRONG>Highlighting,</STRONG> <STRONG>Underlining,</STRONG> <STRONG>and</STRONG> <STRONG>Visible</STRONG> <STRONG>Bells</STRONG> + 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 <EM>stand-</EM> + <EM>out</EM> <EM>mode</EM>, 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 + <STRONG>smso</STRONG> and <STRONG>rmso</STRONG>, 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 <STRONG>xmc</STRONG> should be given to tell how many spaces are left. + + Codes to begin underlining and end underlining can be + given as <STRONG>smul</STRONG> and <STRONG>rmul</STRONG> 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 <STRONG>uc</STRONG>. + + Other capabilities to enter various highlighting modes + include <STRONG>blink</STRONG> (blinking) <STRONG>bold</STRONG> (bold or extra bright) <STRONG>dim</STRONG> + (dim or half-bright) <STRONG>invis</STRONG> (blanking or invisible text) + <STRONG>prot</STRONG> (protected) <STRONG>rev</STRONG> (reverse video) <STRONG>sgr0</STRONG> (turn off <EM>all</EM> + attribute modes) <STRONG>smacs</STRONG> (enter alternate character set + mode) and <STRONG>rmacs</STRONG> (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 <STRONG>sgr</STRONG> (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 <STRONG>sgr</STRONG>, only those for which + corresponding separate attribute commands exist. + + For example, the DEC vt220 supports most of the modes: + + + <STRONG>tparm</STRONG> <STRONG>parameter</STRONG> <STRONG>attribute</STRONG> <STRONG>escape</STRONG> <STRONG>sequence</STRONG> + + none none \E[0m + p1 standout \E[0;1;7m + p2 underline \E[0;4m + p3 reverse \E[0;7m + p4 blink \E[0;5m + p5 dim not available + p6 bold \E[0;1m + p7 invis \E[0;8m + p8 protect not used + p9 altcharset ^O (off) ^N (on) + + 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 + + + <STRONG>sequence</STRONG> <STRONG>when</STRONG> <STRONG>to</STRONG> <STRONG>output</STRONG> <STRONG>terminfo</STRONG> <STRONG>translation</STRONG> + + \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. Also, some implementations rely on sgr being given + if sgr0 is, Not all terminfo entries necessarily have an + sgr string, however. Many terminfo entries are derived + from termcap entries which have no sgr string. The only + drawback to adding an sgr string is that termcap also + assumes that sgr0 does not exit alternate character set + mode. + + Terminals with the ``magic cookie'' glitch (<STRONG>xmc</STRONG>) 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 + <STRONG>msgr</STRONG> 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 <STRONG>flash</STRONG>; it must not move the cursor. + + If the cursor needs to be made more visible than normal + when it is not on the bottom line (to make, for example, a + non-blinking underline into an easier to find block or + blinking underline) give this sequence as <STRONG>cvvis</STRONG>. If there + is a way to make the cursor completely invisible, give + that as <STRONG>civis</STRONG>. The capability <STRONG>cnorm</STRONG> should be given which + undoes the effects of both of these modes. + + If your terminal correctly generates underlined characters + (with no special codes needed) even though it does not + overstrike, then you should give the capability <STRONG>ul</STRONG>. If a + character overstriking another leaves both characters on + the screen, specify the capability <STRONG>os</STRONG>. If overstrikes are + erasable with a blank, then this should be indicated by + giving <STRONG>eo</STRONG>. + + + <STRONG>Keypad</STRONG> <STRONG>and</STRONG> <STRONG>Function</STRONG> <STRONG>Keys</STRONG> + 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 <STRONG>smkx</STRONG> and + <STRONG>rmkx</STRONG>. 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 <STRONG>kcub1,</STRONG> <STRONG>kcuf1,</STRONG> + <STRONG>kcuu1,</STRONG> <STRONG>kcud1,</STRONG> and <STRONG>khome</STRONG> respectively. If there are func- + tion keys such as f0, f1, ..., f10, the codes they send + can be given as <STRONG>kf0,</STRONG> <STRONG>kf1,</STRONG> <STRONG>...,</STRONG> <STRONG>kf10</STRONG>. If these keys have + labels other than the default f0 through f10, the labels + can be given as <STRONG>lf0,</STRONG> <STRONG>lf1,</STRONG> <STRONG>...,</STRONG> <STRONG>lf10</STRONG>. The codes + transmitted by certain other special keys can be given: + <STRONG>kll</STRONG> (home down), <STRONG>kbs</STRONG> (backspace), <STRONG>ktbc</STRONG> (clear all tabs), + <STRONG>kctab</STRONG> (clear the tab stop in this column), <STRONG>kclr</STRONG> (clear + screen or erase key), <STRONG>kdch1</STRONG> (delete character), <STRONG>kdl1</STRONG> + (delete line), <STRONG>krmir</STRONG> (exit insert mode), <STRONG>kel</STRONG> (clear to end + of line), <STRONG>ked</STRONG> (clear to end of screen), <STRONG>kich1</STRONG> (insert + character or enter insert mode), <STRONG>kil1</STRONG> (insert line), <STRONG>knp</STRONG> + (next page), <STRONG>kpp</STRONG> (previous page), <STRONG>kind</STRONG> (scroll for- + ward/down), <STRONG>kri</STRONG> (scroll backward/up), <STRONG>khts</STRONG> (set a tab stop + in this column). In addition, if the keypad has a 3 by 3 + array of keys including the four arrow keys, the other + five keys can be given as <STRONG>ka1</STRONG>, <STRONG>ka3</STRONG>, <STRONG>kb2</STRONG>, <STRONG>kc1</STRONG>, and <STRONG>kc3</STRONG>. + These keys are useful when the effects of a 3 by 3 direc- + tional pad are needed. + + Strings to program function keys can be given as <STRONG>pfkey</STRONG>, + <STRONG>pfloc</STRONG>, and <STRONG>pfx</STRONG>. A string to program screen labels should + be specified as <STRONG>pln</STRONG>. 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 <STRONG>pfkey</STRONG> causes pressing the given key + to be the same as the user typing the given string; <STRONG>pfloc</STRONG> + causes the string to be executed by the terminal in local; + and <STRONG>pfx</STRONG> causes the string to be transmitted to the com- + puter. + + The capabilities <STRONG>nlab</STRONG>, <STRONG>lw</STRONG> and <STRONG>lh</STRONG> 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 <STRONG>smln</STRONG> and <STRONG>rmln</STRONG>. <STRONG>smln</STRONG> is normally output after one + or more pln sequences to make sure that the change becomes + visible. + + + <STRONG>Tabs</STRONG> <STRONG>and</STRONG> <STRONG>Initialization</STRONG> + If the terminal has hardware tabs, the command to advance + to the next tab stop can be given as <STRONG>ht</STRONG> (usually control + I). A ``back-tab'' command which moves leftward to the + preceding tab stop can be given as <STRONG>cbt</STRONG>. By convention, if + the teletype modes indicate that tabs are being expanded + by the computer rather than being sent to the terminal, + programs should not use <STRONG>ht</STRONG> or <STRONG>cbt</STRONG> even if they are + present, since the user may not have the tab stops prop- + erly set. If the terminal has hardware tabs which are + initially set every <EM>n</EM> spaces when the terminal is powered + up, the numeric parameter <STRONG>it</STRONG> is given, showing the number + of spaces the tabs are set to. This is normally used by + the <EM>tset</EM> 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 <STRONG>is1</STRONG>, <STRONG>is2</STRONG>, and <STRONG>is3</STRONG>, initializa- + tion strings for the terminal, <STRONG>iprog</STRONG>, the path name of a + program to be run to initialize the terminal, and <STRONG>if</STRONG>, 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 <EM>init</EM> option + of the <EM>tput</EM> program, each time the user logs in. They + will be printed in the following order: + + run the program + <STRONG>iprog</STRONG> + + output <STRONG>is1</STRONG> <STRONG>is2</STRONG> + + set the margins using + <STRONG>mgc</STRONG>, <STRONG>smgl</STRONG> and <STRONG>smgr</STRONG> + + set tabs using + <STRONG>tbc</STRONG> and <STRONG>hts</STRONG> + + print the file + <STRONG>if</STRONG> + + and finally + output <STRONG>is3</STRONG>. + + Most initialization is done with <STRONG>is2</STRONG>. Special terminal + modes can be set up without duplicating strings by putting + the common sequences in <STRONG>is2</STRONG> and special cases in <STRONG>is1</STRONG> and + <STRONG>is3</STRONG>. + + A set of sequences that does a harder reset from a totally + unknown state can be given as <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rf</STRONG> and <STRONG>rs3</STRONG>, analo- + gous to <STRONG>is1</STRONG> <STRONG>,</STRONG> <STRONG>is2</STRONG> <STRONG>,</STRONG> <STRONG>if</STRONG> and <STRONG>is3</STRONG> respectively. These + strings are output by the <EM>reset</EM> program, which is used + when the terminal gets into a wedged state. Commands are + normally placed in <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG> <STRONG>rs3</STRONG> and <STRONG>rf</STRONG> only if they pro- + duce annoying effects on the screen and are not necessary + when logging in. For example, the command to set the + vt100 into 80-column mode would normally be part of <STRONG>is2</STRONG>, + but it causes an annoying glitch of the screen and is not + normally needed since the terminal is usually already in + 80 column mode. + + The <EM>reset</EM> program writes strings including <STRONG>iprog</STRONG>, etc., in + the same order as the <EM>init</EM> program, using <STRONG>rs1</STRONG>, etc., + instead of <STRONG>is1</STRONG>, etc. If any of <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, or <STRONG>rf</STRONG> reset + capability strings are missing, the <EM>reset</EM> program falls + back upon the corresponding initialization capability + string. + + If there are commands to set and clear tab stops, they can + be given as <STRONG>tbc</STRONG> (clear all tab stops) and <STRONG>hts</STRONG> (set a tab + stop in the current column of every row). If a more com- + plex sequence is needed to set the tabs than can be + described by this, the sequence can be placed in <STRONG>is2</STRONG> or + <STRONG>if</STRONG>. + + <STRONG>Delays</STRONG> <STRONG>and</STRONG> <STRONG>Padding</STRONG> + Many older and slower terminals do not support either + XON/XOFF or DTR handshaking, including hard copy terminals + and some very archaic CRTs (including, for example, DEC + VT100s). These may require padding characters after cer- + tain cursor motions and screen changes. + + If the terminal uses xon/xoff handshaking for flow control + (that is, it automatically emits ^S back to the host when + its input buffers are close to full), set <STRONG>xon</STRONG>. This capa- + bility suppresses the emission of padding. You can also + set it for memory-mapped console devices effectively that + do not have a speed limit. Padding information should + still be included so that routines can make better deci- + sions about relative costs, but actual pad characters will + not be transmitted. + + If <STRONG>pb</STRONG> (padding baud rate) is given, padding is suppressed + at baud rates below the value of <STRONG>pb</STRONG>. If the entry has no + padding baud rate, then whether padding is emitted or not + is completely controlled by <STRONG>xon</STRONG>. + + If the terminal requires other than a null (zero) charac- + ter as a pad, then this can be given as <STRONG>pad</STRONG>. Only the + first character of the <STRONG>pad</STRONG> string is used. + + + <STRONG>Status</STRONG> <STRONG>Lines</STRONG> + Some terminals have an extra `status line' which is not + normally used by software (and thus not counted in the + terminal's <STRONG>lines</STRONG> capability). + + The simplest case is a status line which is cursor- + addressable but not part of the main scrolling region on + the screen; the Heathkit H19 has a status line of this + kind, as would a 24-line VT100 with a 23-line scrolling + region set up on initialization. This situation is indi- + cated by the <STRONG>hs</STRONG> capability. + + Some terminals with status lines need special sequences to + access the status line. These may be expressed as a + string with single parameter <STRONG>tsl</STRONG> which takes the cursor to + a given zero-origin column on the status line. The capa- + bility <STRONG>fsl</STRONG> must return to the main-screen cursor positions + before the last <STRONG>tsl</STRONG>. You may need to embed the string + values of <STRONG>sc</STRONG> (save cursor) and <STRONG>rc</STRONG> (restore cursor) in <STRONG>tsl</STRONG> + and <STRONG>fsl</STRONG> to accomplish this. + + The status line is normally assumed to be the same width + as the width of the terminal. If this is untrue, you can + specify it with the numeric capability <STRONG>wsl</STRONG>. + + A command to erase or blank the status line may be speci- + fied as <STRONG>dsl</STRONG>. + + The boolean capability <STRONG>eslok</STRONG> specifies that escape + sequences, tabs, etc., work ordinarily in the status line. + + The <STRONG>ncurses</STRONG> implementation does not yet use any of these + capabilities. They are documented here in case they ever + become important. + + + <STRONG>Line</STRONG> <STRONG>Graphics</STRONG> + Many terminals have alternate character sets useful for + forms-drawing. Terminfo and <STRONG>curses</STRONG> build in support for + the drawing characters supported by the VT100, with some + characters from the AT&T 4410v1 added. This alternate + character set may be specified by the <STRONG>acsc</STRONG> capability. + + + <STRONG>Glyph</STRONG> <STRONG>ACS</STRONG> <STRONG>Ascii</STRONG> <STRONG>VT100</STRONG> + <STRONG>Name</STRONG> <STRONG>Name</STRONG> <STRONG>Default</STRONG> <STRONG>Name</STRONG> + UK pound sign ACS_STERLING f } + arrow pointing down ACS_DARROW v . + arrow pointing left ACS_LARROW < , + arrow pointing right ACS_RARROW > + + arrow pointing up ACS_UARROW ^ - + board of squares ACS_BOARD # h + bullet ACS_BULLET o ~ + checker board (stipple) ACS_CKBOARD : a + degree symbol ACS_DEGREE \ f + diamond ACS_DIAMOND + ` + greater-than-or-equal-to ACS_GEQUAL > z + greek pi ACS_PI * { + horizontal line ACS_HLINE - q + lantern symbol ACS_LANTERN # i + large plus or crossover ACS_PLUS + n + less-than-or-equal-to ACS_LEQUAL < y + + lower left corner ACS_LLCORNER + m + lower right corner ACS_LRCORNER + j + not-equal ACS_NEQUAL ! | + plus/minus ACS_PLMINUS # g + scan line 1 ACS_S1 ~ o + scan line 3 ACS_S3 - p + scan line 7 ACS_S7 - r + scan line 9 ACS_S9 _ s + solid square block ACS_BLOCK # 0 + tee pointing down ACS_TTEE + w + tee pointing left ACS_RTEE + u + tee pointing right ACS_LTEE + t + tee pointing up ACS_BTEE + v + upper left corner ACS_ULCORNER + l + upper right corner ACS_URCORNER + k + vertical line ACS_VLINE | x + + The best way to define a new device's graphics set is to + add a column to a copy of this table for your terminal, + giving the character which (when emitted between + <STRONG>smacs</STRONG>/<STRONG>rmacs</STRONG> switches) will be rendered as the correspond- + ing graphic. Then read off the VT100/your terminal char- + acter pairs right to left in sequence; these become the + ACSC string. + + + <STRONG>Color</STRONG> <STRONG>Handling</STRONG> + Most color terminals are either `Tektronix-like' or `HP- + like'. Tektronix-like terminals have a predefined set of + N colors (where N usually 8), and can set character-cell + foreground and background characters independently, mixing + them into N * N color-pairs. On HP-like terminals, the + use must set each color pair up separately (foreground and + background are not independently settable). Up to M + color-pairs may be set up from 2*M different colors. + ANSI-compatible terminals are Tektronix-like. + + Some basic color capabilities are independent of the color + method. The numeric capabilities <STRONG>colors</STRONG> and <STRONG>pairs</STRONG> specify + the maximum numbers of colors and color-pairs that can be + displayed simultaneously. The <STRONG>op</STRONG> (original pair) string + resets foreground and background colors to their default + values for the terminal. The <STRONG>oc</STRONG> string resets all colors + or color-pairs to their default values for the terminal. + Some terminals (including many PC terminal emulators) + erase screen areas with the current background color + rather than the power-up default background; these should + have the boolean capability <STRONG>bce</STRONG>. + + To change the current foreground or background color on a + Tektronix-type terminal, use <STRONG>setaf</STRONG> (set ANSI foreground) + and <STRONG>setab</STRONG> (set ANSI background) or <STRONG>setf</STRONG> (set foreground) + and <STRONG>setb</STRONG> (set background). These take one parameter, the + color number. The SVr4 documentation describes only + <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>; the XPG4 draft says that "If the terminal + supports ANSI escape sequences to set background and fore- + ground, they should be coded as <STRONG>setaf</STRONG> and <STRONG>setab</STRONG>, respec- + tively. If the terminal supports other escape sequences + to set background and foreground, they should be coded as + <STRONG>setf</STRONG> and <STRONG>setb</STRONG>, respectively.

If so, + the <STRONG>initc</STRONG> capability will take a color number (0 to <STRONG>colors</STRONG> + - 1)and three more parameters which describe the color. + These three parameters default to being interpreted as RGB + (Red, Green, Blue) values. If the boolean capability <STRONG>hls</STRONG> + is present, they are instead as HLS (Hue, Lightness, Satu- + ration) indices. The ranges are terminal-dependent. + + On an HP-like terminal, <STRONG>initp</STRONG> may give a capability for + changing a color-pair value. It will take seven parame- + ters; a color-pair number (0 to <STRONG>max_pairs</STRONG> - 1), and two + triples describing first background and then foreground + colors. These parameters must be (Red, Green, Blue) or + (Hue, Lightness, Saturation) depending on <STRONG>hls</STRONG>. + + On some color terminals, colors collide with highlights. + You can register these collisions with the <STRONG>ncv</STRONG> capability. + This is a bit-mask of attributes not to be used when col- + ors are enabled. The correspondence with the attributes + understood by <STRONG>curses</STRONG> is as follows: + + + <STRONG>Attribute</STRONG> <STRONG>Bit</STRONG> <STRONG>Decimal</STRONG> + A_STANDOUT 0 1 + A_UNDERLINE 1 2 + A_REVERSE 2 4 + A_BLINK 3 8 + A_DIM 4 16 + A_BOLD 5 32 + A_INVIS 6 64 + A_PROTECT 7 128 + A_ALTCHARSET 8 256 + + For example, on many IBM PC consoles, the underline + attribute collides with the foreground color blue and is + not available in color mode. These should have an <STRONG>ncv</STRONG> + capability of 2. + + SVr4 curses does nothing with <STRONG>ncv</STRONG>, ncurses recognizes it + and optimizes the output in favor of colors. + + + <STRONG>Miscellaneous</STRONG> + If the terminal requires other than a null (zero) charac- + ter as a pad, then this can be given as pad. Only the + first character of the pad string is used. If the termi- + nal does not have a pad character, specify npc. Note that + ncurses implements the termcap-compatible <STRONG>PC</STRONG> variable; + though the application may set this value to something + other than a null, ncurses will test <STRONG>npc</STRONG> first and use + napms if the terminal has no pad character. + + If the terminal can move up or down half a line, this can + be indicated with <STRONG>hu</STRONG> (half-line up) and <STRONG>hd</STRONG> (half-line + down). This is primarily useful for superscripts and sub- + scripts on hard-copy terminals. If a hard-copy terminal + can eject to the next page (form feed), give this as <STRONG>ff</STRONG> + (usually control L). + + If there is a command to repeat a given character a given + number of times (to save time transmitting a large number + of identical characters) this can be indicated with the + parameterized string <STRONG>rep</STRONG>. The first parameter is the + character to be repeated and the second is the number of + times to repeat it. Thus, tparm(repeat_char, 'x', 10) is + the same as `xxxxxxxxxx'. + + If the terminal has a settable command character, such as + the TEKTRONIX 4025, this can be indicated with <STRONG>cmdch</STRONG>. A + prototype command character is chosen which is used in all + capabilities. This character is given in the <STRONG>cmdch</STRONG> capa- + bility to identify it. The following convention is sup- + ported on some UNIX systems: The environment is to be + searched for a <STRONG>CC</STRONG> variable, and if found, all occurrences + of the prototype character are replaced with the character + in the environment variable. + + Terminal descriptions that do not represent a specific + kind of known terminal, such as <EM>switch</EM>, <EM>dialup</EM>, <EM>patch</EM>, and + <EM>network</EM>, should include the <STRONG>gn</STRONG> (generic) capability so + that programs can complain that they do not know how to + talk to the terminal. (This capability does not apply to + <EM>virtual</EM> terminal descriptions for which the escape + sequences are known.) + + If the terminal has a ``meta key'' which acts as a shift + key, setting the 8th bit of any character transmitted, + this fact can be indicated with <STRONG>km</STRONG>. Otherwise, software + will assume that the 8th bit is parity and it will usually + be cleared. If strings exist to turn this ``meta mode'' + on and off, they can be given as <STRONG>smm</STRONG> and <STRONG>rmm</STRONG>. + + If the terminal has more lines of memory than will fit on + the screen at once, the number of lines of memory can be + indicated with <STRONG>lm</STRONG>. A value of <STRONG>lm</STRONG>#0 indicates that the + number of lines is not fixed, but that there is still more + memory than fits on the screen. + + If the terminal is one of those supported by the UNIX vir- + tual terminal protocol, the terminal number can be given + as <STRONG>vt</STRONG>. + + Media copy strings which control an auxiliary printer con- + nected to the terminal can be given as <STRONG>mc0</STRONG>: print the con- + tents of the screen, <STRONG>mc4</STRONG>: turn off the printer, and <STRONG>mc5</STRONG>: + turn on the printer. When the printer is on, all text + sent to the terminal will be sent to the printer. It is + undefined whether the text is also displayed on the termi- + nal screen when the printer is on. A variation <STRONG>mc5p</STRONG> takes + one parameter, and leaves the printer on for as many char- + acters as the value of the parameter, then turns the + printer off. The parameter should not exceed 255. All + text, including <STRONG>mc4</STRONG>, is transparently passed to the + printer while an <STRONG>mc5p</STRONG> is in effect. + + + <STRONG>Glitches</STRONG> <STRONG>and</STRONG> <STRONG>Braindamage</STRONG> + Hazeltine terminals, which do not allow `~' characters to + be displayed should indicate <STRONG>hz</STRONG>. + + Terminals which ignore a line-feed immediately after an <STRONG>am</STRONG> + wrap, such as the Concept and vt100, should indicate <STRONG>xenl</STRONG>. + + If <STRONG>el</STRONG> is required to get rid of standout (instead of + merely writing normal text on top of it), <STRONG>xhp</STRONG> should be + given. + + Teleray terminals, where tabs turn all characters moved + over to blanks, should indicate <STRONG>xt</STRONG> (destructive tabs). + Note: the variable indicating this is now + `dest_tabs_magic_smso'; in older versions, it was tel- + eray_glitch. This glitch is also taken to mean that it is + not possible to position the cursor on top of a ``magic + cookie'', that to erase standout mode it is instead neces- + sary to use delete and insert line. The ncurses implemen- + tation ignores this glitch. + + The Beehive Superbee, which is unable to correctly trans- + mit the escape or control C characters, has <STRONG>xsb</STRONG>, 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 <STRONG>x</STRONG><EM>x</EM>. + + + <STRONG>Similar</STRONG> <STRONG>Terminals</STRONG> + If there are two very similar terminals, one (the variant) + can be defined as being just like the other (the base) + with certain exceptions. In the definition of the vari- + ant, the string capability <STRONG>use</STRONG> can be given with the name + of the base terminal. The capabilities given before <STRONG>use</STRONG> + override those in the base type named by <STRONG>use</STRONG>. If there + are multiple <STRONG>use</STRONG> capabilities, they are merged in reverse + order. That is, the rightmost <STRONG>use</STRONG> reference is processed + first, then the one to its left, and so forth. Capabili- + ties given explicitly in the entry override those brought + in by <STRONG>use</STRONG> references. + + A capability can be canceled by placing <STRONG>xx@</STRONG> to the left of + the use reference that imports it, where <EM>xx</EM> is the capa- + bility. For example, the entry + + 2621-nl, smkx@, rmkx@, use=2621, + + defines a 2621-nl that does not have the <STRONG>smkx</STRONG> or <STRONG>rmkx</STRONG> + capabilities, and hence does not turn on the function key + labels when in visual mode. This is useful for different + modes for a terminal, or for different user preferences. + + + <STRONG>Pitfalls</STRONG> <STRONG>of</STRONG> <STRONG>Long</STRONG> <STRONG>Entries</STRONG> + Long terminfo entries are unlikely to be a problem; to + date, no entry has even approached terminfo's 4096-byte + string-table maximum. Unfortunately, the termcap transla- + tions are much more strictly limited (to 1023 bytes), thus + termcap translations of long terminfo entries can cause + problems. + + The man pages for 4.3BSD and older versions of <STRONG>tgetent()</STRONG> + instruct the user to allocate a 1024-byte buffer for the + termcap entry. The entry gets null-terminated by the + termcap library, so that makes the maximum safe length for + a termcap entry 1k-1 (1023) bytes. Depending on what the + application and the termcap library being used does, and + where in the termcap file the terminal type that <STRONG>tgetent()</STRONG> + is searching for is, several bad things can happen. + + Some termcap libraries print a warning message or exit if + they find an entry that's longer than 1023 bytes; others + do not; others truncate the entries to 1023 bytes. Some + application programs allocate more than the recommended 1K + for the termcap entry; others do not. + + Each termcap entry has two important sizes associated with + it: before "tc" expansion, and after "tc" expansion. "tc" + is the capability that tacks on another termcap entry to + the end of the current one, to add on its capabilities. + If a termcap entry does not use the "tc" capability, then + of course the two lengths are the same. + + The "before tc expansion" length is the most important + one, because it affects more than just users of that par- + ticular terminal. This is the length of the entry as it + exists in /etc/termcap, minus the backslash-newline pairs, + which <STRONG>tgetent()</STRONG> strips out while reading it. Some termcap + libraries strip off the final newline, too (GNU termcap + does not). Now suppose: + + * a termcap entry before expansion is more than 1023 + bytes long, + + * and the application has only allocated a 1k buffer, + + * and the termcap library (like the one in BSD/OS 1.1 + and GNU) reads the whole entry into the buffer, no + matter what its length, to see if it is the entry it + wants, + + * and <STRONG>tgetent()</STRONG> is searching for a terminal type that + either is the long entry, appears in the termcap file + after the long entry, or does not appear in the file + at all (so that <STRONG>tgetent()</STRONG> has to search the whole + termcap file). + + Then <STRONG>tgetent()</STRONG> will overwrite memory, perhaps its stack, + and probably core dump the program. Programs like telnet + are particularly vulnerable; modern telnets pass along + 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 <STRONG>tgetent()</STRONG> only does "tc" expan- + sion once it is 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 is 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 <STRONG>ncurses</STRONG> imple- + mentation of <STRONG><A HREF="tic.1m.html">tic(1m)</A></STRONG> issues warning messages when the pre- + tc length of a termcap translation is too long. The -c + (check) option also checks resolved (after tc expansion) + lengths. + + <STRONG>Binary</STRONG> <STRONG>Compatibility</STRONG> + It is not wise to count on portability of binary terminfo + entries between commercial UNIX versions. The problem is + that there are at least two versions of terminfo (under + HP-UX and AIX) which diverged from System V terminfo after + SVr1, and have added extension capabilities to the string + table that (in the binary format) collide with System V + and XSI Curses extensions. + + +</PRE> +<H2>EXTENSIONS</H2><PRE> + Some SVr4 <STRONG>curses</STRONG> implementations, and all previous to + SVr4, do not interpret the %A and %O operators in parame- + ter strings. + + SVr4/XPG4 do not specify whether <STRONG>msgr</STRONG> licenses movement + while in an alternate-character-set mode (such modes may, + among other things, map CR and NL to characters that do + not trigger local motions). The <STRONG>ncurses</STRONG> implementation + ignores <STRONG>msgr</STRONG> in <STRONG>ALTCHARSET</STRONG> mode. This raises the possi- + bility that an XPG4 implementation making the opposite + interpretation may need terminfo entries made for <STRONG>ncurses</STRONG> + to have <STRONG>msgr</STRONG> turned off. + + The <STRONG>ncurses</STRONG> library handles insert-character and insert- + character modes in a slightly non-standard way to get bet- + ter update efficiency. See the <STRONG>Insert/Delete</STRONG> <STRONG>Character</STRONG> + subsection above. + + The parameter substitutions for <STRONG>set_clock</STRONG> and <STRONG>dis-</STRONG> + <STRONG>play_clock</STRONG> are not documented in SVr4 or the XSI Curses + standard. They are deduced from the documentation for the + AT&T 505 terminal. + + Be careful assigning the <STRONG>kmous</STRONG> capability.
