newterm() argument is const in the spec, so this fixes our
conformance.
setterm() is not in the spec, but it's natural and in ncurses its
argument is const too, so follow suit.
Doesn't change the ABI, so no bump required.
ok blymn@
the number of bytes to add - for multibyte characters n will be > 1.
Fix __slk_draw to pass in the actual length of the label instead of
the default label length because wide characters may make the
actual string length longer than the slk display length.
on virtscr and curscr because the indexes past are supposed to be
one *past* the last matching line (they may actually match if the line is
at the bottom of the screen). Iff they don't match reduce the scroll
region size by one so we don't scroll non-matching lines, also check
if the region is then 0 after the decrement and just return if it was.
This fixes observed behviour in the PR. Allow the cursor to be
moved one past the EOL, if postitioned here then set ISPASTEOL.
also protect out of range access if win->cury is past maxy.
- 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.
same as the old one. This prevents excessive redraws in some
applications.
* Fix bug introduced when wbkgrndset was fixed, we cannot blindly
replace any instance of the old background character with the new one
because some of those characters were put there by the application
leading to display corruption. So flag characters as background when
they are erased and only update the flagged characters when setting
the background.
* Fix bkgrndset so that it actually sets the background character in
in line with the SUSv2 specification.
* Add an internal function to copy a complex character
* Make the previously static celleq function into a libcurses private
function so that it can be called in other files.
* Remove the WCOL family of macros, these were "stealing" the upper bits
of a character attribute to store the column width of a character. No
warning was given about this in curses.h which meant it was easy to
accidentally reuse the bits in use by the WCOL macros (we already did).
Add couple of 16bit ints to the character structure iff HAVE_WCHAR is
true to hold the display width and wide char related flags (just
continuation at the moment)
* Convert all instances of WCOL macros to just reference the column width
in the char structure so it is not obfuscated.
* Fix cursor positioning so placing a cursor in the middle of a wide char
actually does just that.
* Fix plod so it understands that if the cursor is going to be positioned
in the middle of a wide char it cannot just reprint the char to get there.
* Fix plodput so it correctly counts the number of output characters for
wide characters.
* Fix slk routines to properly size the wctomb() buffer.
