These notes are for ncurses + @VERSION@, released January 27, 2018.+ +
This release is designed to be source-compatible with + ncurses 5.0 through 6.0; providing + extensions to the application binary interface (ABI). Although + the source can still be configured to support the ncurses 5 ABI, the intent of the release is to + provide extensions to the ncurses + 6 ABI:+ +
improve integration of tput + and tset+
provide support for extended numeric capabilities.+
There are, of course, numerous other improvements, listed in + this announcement.+ +
The release notes also mention some bug-fixes, but are focused + on new features and improvements to existing features since + ncurses 6.0 release.+ +
The improved integration of tput and tset + made only small changes to the libraries. However, supporting + extended numeric capabilities required a few changes:+ +
TERMINAL structure in
<term.h> is now opaque. Doing that allowed
+ making the structure larger, to hold the extended numeric
A few applications required changes during development of + ncurses 6.1 because those + applications misused the members of that structure, e.g., + directly modifying it rather than using + def_prog_mode.+
TERMINAL opaque (and because none
+ of the library functions use anything except a pointer to
TERMINAL), it was possible to increase the size
+ of the structure, adding to the end.
Existing applications which were linked to the
+ ncurses 6.0 high-level
+ (ncurses, ncursesw) and low-level
+ (tinfo, tinfo) libraries should not require
+ re-linking since the binary interface did not change, nor did
+ the structure offsets with
A few applications use the inner
+ structure's offsets to refer to terminfo capabilities within
+ that structure. Again, those do not require modification
+ because their offsets within
TERMINAL did not
When configured for wide-characters, i.e.,
+ “ncursesw” the
TERMINAL structure is
The new data in
TERMINAL holds the same
+ information as
TERMTYPE, but with larger numbers
+ (“int” versus “short”). It is named
The library uses this structure internally in preference
TERMTYPE, referring to
+ only to initialize it for applications that use the
+ capabilities defined in
When configured for 8-bit (narrow) characters, the
TERMTYPE2 structure is not used.
The motivation for making this extension came from noticing + that + termcap applications could (though not + realistically) use larger numbers than would fit in 16-bits, + and the fact that the number of color pairs for a 256-color xterm + could not be expressed in terminfo (i.e., 32767 versus 65536). + Also, a few terminals support direct-colors, which could use the + extension.+ +
Generally speaking, applications that use internal details of
+ a library are unsupported. There was exactly one exception for
+ ncurses: the tack program used the internal
+ details of
TERMINAL, because it provides an
+ ncurses-specific feature for interactively modifying a terminfo
+ description and writing the updated description to a text-file.
+ It was possible to not only separate tack from these internal
+ details of ncurses, but to
+ generalize it so that the program works with Unix curses
+ (omitting the ncurses-specific feature). That was released as
+ tack 1.08 in July
While making changes to tack to + eliminate its dependency upon ncurses internals, the publicly-visible + details of those internals were reviewed, and some symbols were + moved to private header files, while others were marked + explicitly as ncurses internals. + Future releases of ncurses may + eliminate some of those symbols (such as those used by + tack 1.07) because they are + neither part of the API or the ABI.+ +
TERMTYPE2 extended numeric
+ capabilities, it is possible to support both color pair values
+ and color values past 32767. Taking compatibility into account,
+ developers readily understand that neither function signatures
+ nor structure offsets change. Also, existing functions have to
+ operate with the extended numbers. Most of that work is internal
+ to the library. For the external interfaces, a hybrid approach
+ was used:
X/Open Curses defined function prototypes such as
wattr_set with an unused parameter, for
+ “future” use. After 25 years, the future is here:
+ ncurses uses the parameter to
+ augment color pair values as described in the
+ manual page.
Other functions such as those defining color pairs did not
+ have a corresponding reserved parameter. For those,
+ ncurses defines extended
+ versions such as
Additionally, to improve performance other changes (and + extensions) are provided in this release:+ +
Several new functions simplify management of large sets of
+ color pairs:
New "RGB" extension capability for direct-color support is
+ used to improve performance of
colorpair_t is now a struct,
+ eliminating an internal 8-bit limit on colors
SCREEN's color-pair table
+ starts small, grows on demand up to the limit given in the
+ terminal description.
getcchar now treat
+ a negative color-pair as an error.
These are new or revised features:+ +
c++/etip.h.in to accommodate
+ deprecation of throw and throws in c++17
add new function
add option to preserve leading whitespace in form + fields+
add a macro for
is_linetouched and adjust the
+ function's return value to make it possible for most
+ applications to check for an error-return.
add build-time utility
report_offsets to help
+ show when the various configurations of tinfo library are
+ compatible or not.
These were done to limit or ultimately deprecate features:+ +
drop two symbols obsoleted in 2004:
+ since they are not part of the suggested ABI6.
mark some structs in form/menu/panel libraries as + potentially opaque without modifying API/ABI.+

While reviewing user feedback, it became apparent that the + differences between + reset (an alias for + tset) and “tput reset” were confusing:+ +
On further investigation, it turned out that the differences + were largely an accident due to the way those programs had + evolved.+ +
This release eliminates the unnecessary differences, using the + same approach for tput's + init (initialization), reset and clear + operations as the separate + reset and + clear programs. Doing this does not change the + command-line options; existing scripts are unaffected.+ +
These are the user-visible changes for the three programs + (tput, tset and clear):+ +
add the terminal-mode parts of “reset” (aka tset) to the “
+ reset” command, making the two almost the same
+ except for window-size.
improve tput's check for + being called as “init” or “reset” to + allow for transformed names.+
add “clear” as a possible link/alias to + tput.+
amend changes for tput to + reset tty modes to “sane” if the program is run + as “reset”, like tset. Likewise, ensure that tset sends either reset- or + init-strings.+
-x option to clear/tput
+ to make the
E3 extension optional
add functionality of
tset -w” to tput, like the
-c” feature this is not optional in
+ clear command for
+ compatibility with tput.
drop long-obsolete “
+ from tset.
modify tset's assignment to
TERM in its output to reflect the name by which
+ the terminal description is found, rather than the primary
+ name. That was an unnecessary part from the initial
+ conversion of tset from
+ termcap to terminfo. The termcap library in 4.3BSD did this
+ to avoid using the short 2-character name
remove a restriction in tput's support for termcap names which + omitted capabilities normally not shown in termcap + translations+
add usage message to clear + command+
improve usage messages for tset and tput.+
Other user-visible improvements and new features include:+ +

+ to force long strings to wrap.

+ if a “
-T” option gives a suitable
+ terminal name.
improve error message from tset/reset + when both stderr/stdout are redirected to a file or pipe.+
Several of the less apparent features deal with translation of + terminfo to termcap (and the reverse), with corresponding checks + by tic:+ +
modify check in
fmt_entry to handle a
+ cancelled reset string. Make similar fixes in other parts of
correct read of terminfo entry in which all strings are + absent or explicitly cancelled. Before this fix, the result + was that all were treated as only absent.+
modify infocmp to suppress
+ mixture of absent/cancelled capabilities that would only show
+ as “
NULL, NULL”, unless the
-q” option is used, e.g., to show
-, @” or “
correct a warning from tic + about keys which are the same, to skip over missing/cancelled + values.+
add check in tic for use of

add check in tic for
+ unnecessary use of “

+ shifted special key.
improve check in tic for + delays by also warning about beep/flash when a delay is not + embedded, or if those use the VT100 reverse video escape + without using a delay.+
improve checks in
trim_sgr0, comp_parse.c and
+ parse_entry.c, for cancelled string capabilities.
add check in tic for some + syntax errors of delays, as well as use of proportional + delays for non-line capabilities.+
add check in tic for

Along with the library and utilities, many improvements were + made to the ncurses-examples.+ +
These changes were made to demonstrate new extensions in + ncurses:+ +
This program iterates over the possible color + combinations, allocating or initializing color pairs. For + best results, choose screen-width dividing evenly into the + number of colors. e.g.,+ +
++ + + +
256 colors+ ++ + + +
88 colors+ ++ + +
add extended_color program, + like the older color_set + program, but using the extended color functions, with and + without the SP-functions interface.+
add picsmap program to fill + in some testing issues not met by dots, using this as the third example in a + comparison of the + ncurses versus slang libraries.+ +
The program can directly read X bitmap and pixmap files, + displaying a picture. It can read other image files using + ImageMagick's convert program to translate the image + into text.+ +
For 16-, 88- and 256-color terminal descriptions,
+ picsmap can load a palette
+ file which tells it which color palette entries to use. For
+ direct-colors, the terminal descriptions use the
RGB extension capability.
There are other new example programs and a few scripts:+ +
add dots_xcurses program to + illustrate a different approach used for extended colors + which can be contrasted with dots_curses.+
add list_keys program show + function keys for one or more terminal descriptions. It uses + ncurses's convention of + modifiers for special keys, based on xterm.+
add padview program, to + compare pads with direct updates in the view program.+

add tput-colorcube demo + script, imitating xterm's 88- and 256-color scripts using + tput.+
add tput-initc script to + demonstrate how tput may be + used to initialize a color palette from a data file.+
A variety of improvements were made to existing programs, both + new features as well as options added to make the set of programs + more consistent.+ +
The ncurses program is the + largest; a proportionately large number of changes were made to + it:+ +
modify a/A screens to make exiting on an escape character + depend on the start of keypad and timeout modes, to allow + better testing of function-keys.+ +
t” toggle for

initc- capabilities to
This includes utilities such as tic and infocmp, because (as noted in New features), the feature + relies upon an extension to the low-level tinfo + library.+
A few software packagers use a configuration option of + ncurses which allows the + low-level tinfo library to be shared between the + high-level ncurses and ncursesw libraries. + This new feature was designed to work in that configuration + as well.
Other applications (i.e., using the 8-bit ncurses + library) which read the extended terminal descriptions see those + numeric capabilities set to the maximum value for a signed 16-bit + number.+ +
Older versions of ncurses' + tic accept out-of-range numeric + capabilities, storing those as the maximum value for a signed + 16-bit number. Other implementations of curses (mentioned in the + discussion of + picsmap) give zero for these + out-of-range capabilities.+ +
These changes provide support for tack 1.08, released in + July 2017:
--without-tack configure option to refine
--with-progs configure option. Normally
+ tack is built outside the
+ ncurses tree, but a few
+ packagers combine it during the build. If
term_entry.h is installed, there is no advantage
+ to in-tree builds.
getccharto - count the trailing null which is documented in - X/Open.
unctrlto obtain a printable version of - the control character, but was not passing color or - video attributes.
waddch_literal, updating - line-pointer after a multicolumn character is found to - not fit on the current row, and wrapping is done. Since - the line-pointer was not updated, the wrapped - multicolumn character was written to the beginning of - the current row.
wins_nwstrand related - functions to ensure that special characters, i.e., - control characters are handled properly with the - wide-character configuration.
_nc_insert_chto use -
_nc_insert_wchwhen inserting wide - characters, since the
wins_wchfunction - that it used did not update the cursor position.
adjust configure-script to define
HAVE_CURSES_DATA_BOOLNAMES symbol needed for
+ tack 1.08 when built in-tree.
+ Rather than relying upon internal "_nc_" functions,
+ tack now uses the boolean,
+ number and string capability name-arrays provided by
+ ncurses and SVr4 Unix curses.
+ It still uses
term_entry.h for the definitions
+ of the extended capability arrays.
add dependency upon ncurses_cfg.h to tic's header-files; any program using + tic-library will have to + supply this file. Legacy tack + versions supply this file; ongoing tack development has dropped the + dependency upon tic-library + and new releases will not be affected.+
Gpm_Openreturns a -2, - e.g., for "xterm". This is normally suppressed but can - be overridden using

correct result of configure option
--without-fallbacks, which caused FALLBACK_LIST
+ to be set to "no"
--with-pkg-config-libdir option to

+ cleanup-changes for 20000708.
Many of the portability changes are implemented via the + configure script:-
$CCenvironment variable - which is defined by X/Open as a curses feature, to - ignore it if it is not a single character.
improve configure script's
+ macro to allow for compiler wrappers such as ccache. This change moves only the
+ preprocessor, optimization and warning flags to

--with-database, - which was coded as an enable-type switch.
the menus library, supporting a uniform but flexible + interface for menu programming.+
the form library, supporting data collection through + on-screen forms.

The ncurses package also has + many useful extensions over SVr4:-
ncurses*-configand pc-files to add - dependency for tinfo library.
The API is 8-bit clean and base-level conformant with the + X/OPEN curses specification, XSI curses (that is, it + implements all BASE level features, and most EXTENDED + features). It includes many function calls not supported + under SVr4 curses (but portability of all calls is documented + so you can use the SVr4 subset only).+
