- Disambiguate the docs for ncplane_erase()
- Add ncpile_top(), ncpile_bottom()
- Refuse attempts to modify the standard plane's resizecb
- Copy alignment and resizecb in ncplane_dup()
- Add cell_load_egc32()
notcurses_enable_cursor() now accepts placement arguments.
both it and notcurses_disable_cursor() now return int rather
than void. add notcurses_cursor_move_yx().
* Reimplement the widget zoo demo. The previous PoC
was a multithreaded monster with behavior dependent
on screen geometry. Replace it with a single thread state
machine. Closes#936.
* Support titles for ncplot. Adds title to the ncplot_options
struct, which may be NULL. Closes#941 .
* Properly color ncplot according to maxchannels and
minchannels. Closes#940
* Add tools/function-table.sh script for generating public API list.
Get notcurses-tetris working again, since its collision
detection relied on simple vs non-simple EGCs, which are
no longer an operative concept. Closes#899.
not caring about endianness is the opiate of the masses.
happy, happy masses. remove endianness.h and all its baleful
influence by explicitly breaking up the cell structure. #892
New reel layout algorithm based on trimming and sifting. Fixes the original issue of #818, though I'm not marking that bug fixed until I've resolved the little issues remaining with this one.
Back off CMake version dependency, see if we can get by with 3.11.4 for EPEL8 #851
Simplify tablet drawing tremendously by separating tablet border and data planes. Callbacks no longer need worry about the borders; they can simply fill the plane they're handed. #833
Improve notcurses_debug() a bit
Add ncplane_new_named() and friends to expose plane naming to the user.
Add internal ncplane_genocide() to kill a plane and all its bound descendents
New industrial-strength ncreel unit testing
notcurses-ncreel now accepts -ln for log level n
Add ncplane_parent() and ncplane_parent_const()
Tons of work on ncreel (#627, #749, #694)
Improve reel demo: get input wired up once more, avoid the FPS demo at bottom, print pointer and line count in each tablet, use new ncreel API. Improve notcurses-ncreel explorer: kill memory leaks (#694), draw tablets better, use new ncreel API. Fix bug in ncreel core where cruft could be left on the screen, via a very gross brute force algorithm. I'll likely come back and make this a bit less ghastly in the future #749. Remove weird one-off input system from ncreel, residue from outcurses. Make some of the normalizing changes speced out in #627

CELL_ALPHA_OPAQUE et al were defined as 0..3, meaning
CELL_ALPHA_SHIFT had to be used to compare them to their
channel representations. Instead, define them in said
representation outright, eliminating the need to shift while
retaining arithmetic properties, and zero initialization for
CELL_ALPHA_OPAQUE. Eliminate CELL_ALPHA_SHIFT #738.
We're not using NCBLIT_2x2 by default because it warps the
aspect ratio. If we're using NCSCALE_STRETCH, though, we've
(1) already indicated that aspect ratio isn't terribly
important to us and (2) are trying to maximize the space.
Since NCBLIT_2x2 is best for large images anyway, make it
the default when NCSCALE_STRECTH is being used.
Remove all explicit uses of NCBLIT_2x2 when NCSCALE_STRETCH
is being used in notcurses-demo.
Add convenience function ncplane_home(). Add an ncblitter_e param
to ncplane_qrcode(), and split int maxversion into value-result
int* ymax and int* xmax. Write the actual sizes of the resulting
visual into these parameters. Update the qrcode demo. Add the
qrcode PoC. Update demos to ncplane_home(), where possible.
ncplane_qrcode() now takes an ncblitter_e and two value-result int*s
in the place of a single value int. The final size of the displayed qrcode
is written to *ymax and *xmax. If the code can't fit within the specified
dimensions, an error is returned. Standard rules for pluggable blitters
apply regarding fallback etc. #699
The Plot unit tests were reaching directly into the objects,
which meant the implementations couldn't include anything
we didn't want public. This was annoying, so I've changed it.
This required adding ncdplot_sample() and ncuplot_sample(),
which we should have had anyway.
Each plane has a "base cell", which like all other cells is
initialized to the null glyph, opaque default foreground color,
and opaque default background color. Prior to this change, at
each cell of a plane, we decided whether to use that cell (the
"viscell") or the base cell depending on whether the viscell had
a non-null glyph. We now evaluate each component independently.
If the viscell has a null glyph, we use the base cell's glyph.
If the viscell has a default foreground, we use the base's fg.
If the viscell has a default background, we use the base's bg.
This was done because (a) it seems more intuitive (if I set a cell
to red, I expect red, not red iff there's a glyph in that cell
for this plane), and (b) because otherwise it was impossible to
do a multicolor overlay without blowing away underlying glyphs
(since without a glyph, you always reduced to the same base cell,
which could have only one fore- and background per render).
Existing code will need to change any instances where cells
lacking glyphs are colored, and those colors are not desired.
Since any such coloring had no effect before, it seems unlikely
that any ought exist (this did bring to light an instance in
the "qrcode" demo where we were staining overmuch of the plane).
This closes#395, the last big open worry regarding our API.
In order to properly determine the scaling of an ncvisual to
be rendered, ncvisual_geom() needs know the blitting method.
For this reason, it took an ncblitter_e argument. It also,
however, needs handle degradation, which means knowing whether
NCVISUAL_OPTIONS_NODEGRADE is in use. It thus really wants the
struct ncvisual_options. Pass and accept it. Closes#697, and
fixes the "yield" demo in ASCII mode (#696).
Very simple take at ncplane_puttext(), a new function for linebroken text. Also some very basic unit tests. I doubt this works very well yet, but it handles the simplest cases #682. Added nclog(), internal function for logging. #520
