blymn ee6c5161ec Fixes for lib/56926 amongst other things: 
- plod now correctly accounts for wide characters when plodding
 - use erase line when in color mode if the terminal has the capability
 - ensure that the CA_CONTINUATION flag is applied consistently to the
   subsequent characters in a wide character.
 - fix a bunch of refresh bugs that caused inconsistent placement of
   wide characters.

blymn 301bf8cc44 Make the default colour pair be pair 0 which appears to match other 
curses implementations.

uwe 017b38e5d1 curses: spell "foreground" correctly in comments 2021-12-17 03:50:18 +00:00
rin b09154d5e3 Style fixes most for __CTRACE(). 2021-09-06 07:45:48 +00:00
rin 0bd3a62045 Expand __CTRACE() to __nothing #ifndef DEBUG.

rin 19d0649ccf Fix old-style definition: use_default_colors() --> use_default_colors(void) 2021-09-06 02:48:54 +00:00

White space police.
Sprinkle some extra braces to make the flow more clear.

No functional changes.

roy 330e363652 Now that we have the initialize_color capability, 
init_color can be made to work.

roy 4060cbcd0c Use tiparm instead of vtparm. 2011-10-03 12:32:15 +00:00
blymn 0a965fa7ed Back out change for assume_default_colors as it was not correct. 2011-01-06 11:29:40 +00:00
blymn 58f5b3b32b Ignore request to change the values of colour pair 0

to assume_default_colors()
 2010-12-25 10:05:08 +00:00
roy 98eb889579 Userland now builds and uses terminfo instead of termcap. 
OK: core@, jdc@
 2010-02-03 15:34:37 +00:00
roy 43d5eb454b Prepare curses for the possibility of changing from termcap to terminfo. 
term.h #defines lines, pad_char and no_color_video macros which conflict
with existing curses code. We change lines to alines and nlines depending
on use, pad_char to padchar and no_color_video becomes no_color_attributes
but with a strong alias from no_color_video.

jdc 1f221324cf Add debug "areas" that allow selective debugging by setting the 
"CURSES_TRACE_MASK" environment variable.  Postive vales include
debug areas, negative values exclude them.
 2007-01-21 13:25:36 +00:00
jdc c4b88fb280 Make sure we update the correct window when changing colour pairs. 2006-08-23 19:20:37 +00:00
jdc 978ab4ad4e Background characters and attributes don't need to be kept per character 
cell, as they are merged when characters are added.  Remove the per cell
storage and clarify the manual page.  Pointed out by ruibiao@.
 2006-01-15 11:43:54 +00:00
jdc 140349e83f Because we are changing the libcurses major number, remove can_change_colors() 
and change the attribute definitions so that we can support more colour pairs.
 2004-03-22 18:57:38 +00:00
jdc ed325dfb85 Accept any negative number of init_pair(). Noticed by Peter Bex. 
Swap red/blue and yellow/cyan if necessary in assume_default_colors().
 2004-03-16 07:52:43 +00:00

(approved by Brett Lumn)
 2003-02-17 11:07:19 +00:00
jdc a3ce96fb84 Rename can_change_colors() to can_change_color(). 
Add can_change_colors() (that just calls can_change_color()).
Add no_color_video().
Replace __nca with _cursesi_screen->nca.
 2003-01-27 21:06:16 +00:00
jdc 1cac4d45c4 Don't allow default colour setting to be overwritten in init_pair(). 
(Also noticed by Pooka).
 2002-11-25 09:11:18 +00:00
blymn d5dc62cbd8 Fix lint nits mainly with the len parameter type in hash_more. 2002-10-22 11:37:34 +00:00
jdc 4eb3ef3dac Set the curses default colours to white on black when using colour. 
See the Single UNIX Specification, Version 2 :

  http://www.opengroup.org/onlinepubs/007908799/xcurses/can_change_color.html

Also, add the functions :

	use_default_colors();
	assume_default_colors(fore, back);

(from ncurses) that allow the terminal default colours or user-specified
default colours to be used.

jdc 606508da77 Rename variables refering to termcap capabilities from NN to __tc_nn. Case 
adjusted to match termcap capability.  A few other variable names renamed too
(ones related to or derived from termcap variables).
 2000-12-19 21:34:24 +00:00
jdc 20e0a208fb Only return TRUE if we can actually manipulate colours. 2000-05-06 19:03:39 +00:00

jdc 8e3f558953 Don't reset firstchp and lastchp even if this line was not dirty. 
They could have been set previously by a parent window or sub-window.
 2000-04-15 22:53:05 +00:00
blymn aaf74682b9 Added functions to replace what were previously macros in curses.h 
(this is a requirement of SUSv2) - the old macro behaviour can be
restored by defining _CURSES_USE_MACROS.
Changed function prototypes to use ANSI style.
All externally visible functions now have ANSI style declarations.
