Add `notcurses_check_pixel_support()` and
`ncdirect_check_pixel_support()` per #1367. Removes
NCOPTION_VERIFY_SIXEL, again per #1367. Adds
`free_terminfo_cache()`, and calls it from both
`notcurses_stop_minimal()` and `ncdirect_stop()`.
Update all documentation. Closes#1371 and #1367.
Looks like the release process used a regex(?) to replace that included some
unintended targets. Microsoft link broke in 2.2.0; CELL_ALPHA_TRANSPARENT
continually replaced since 2.0.1.
Extract Curses differences and adaptation sections, and
move them to doc/CURSES.md. Reference this new document
in README.md. We now have sufficiently few sections that
we can dispense with the ToC. Do so.
Eliminate NCDIRECT_OPTION_NO_READLINE (it was only introduced in
Notcurses 2.1.6). Add a new function, ncdirect_readline(). Upon
first call to this function, initialize libreadline. Destroy
libreadline in ncdirect_stop() iff we initialized it. Add
hilodirect guessing game PoC from #1325. Rename
notcurses_directmode.3 to notcurses_direct.3. Closes#1326.
Implement channels_set_fg_palindex() and channels_set_bg_palindex()
in terms of channel_set_palindex(). Add missing entries to
notcurses_channels.3 man page. Use uint32_t in place of unsigned
when dealing with channels in notcurses.h.
This completes the work for #1068. This addressed a subtle issue.
When we're using pixel->semigraphic art, we want slightly different
rendering. Essentially, imagine that we have two images, each two
pixels tall and one pixel wide. The top image is a transparent pixel
above a white pixel. The bottom image is a white pixel above a black
pixel. We'd expect the result to be two white pixels, but we can
instead get a black pixel above a white pixel. This is because the
*background* color is being merged from the bottom plane, but really
we want the *top* color. Ncvisuals are now blitted along with
information regarding which quadrants they draw over, and when
appropriate, we invert the foreground and background. Closes#1068.
Extract `libnotcurses-core` from `libnotcurses`. The former contains everything except multimedia code. The latter contains multimedia stuff (a wrapper around FFmpeg or OIIO). If built with `-DUSE_MULTIMEDIA=none`, there will not be any `libnotcurses.so` generated. `libnotcurses.so` uses library constructors/destructors to insert its implementation into the `ncvisual` stack at runtime. Users linking `-lnotcurses` will get the full implementation; users linking `-lnotcurses-core` only will get the stack less multimedia code.
The upshot of this is that someone can compile/install only `libnotcurses-core`, and a program linked against it will work just fine. This eliminates the need to install the full (large) dependency stack of the multimedia code unless necessary. This will hopefully be useful for e.g. installers etc. Closes#339.
ncplane_destroy() needs to call ncplane_reparent_family(), not
ncplane_reparent() as it was doing (closes#1291). ->absy and
->absx actually are absolute; return them directly for an O(1)
ncplane_abs_yx() (down from O(N), huzzah). Add some unit tests
related to destroying and reparenting (#1286). Add ncplane_abs_y()
and ncplane_abs_x(), document them, etc.
Improve the documentation for ncplane_set_base_cell() and
ncplane_set_base(). Go by render.c's authority (all three
channels are independently checked for transparency, and
replaced with the base cell if so--egc, fg, and bg). Add a
BASE CELL section to notcurses_plane.3. Check for, and reject,
an nccell which is secondary among a multicolumn EGC.
Closes#1238.
- 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()
CMake:
Simplify cmake target+version config generation and make it actually
work. With the changes it is now possible to detect and use
`Notcurses` in the following way:
find_package(Notcurses REQUIRED)
...
target_link_libraries(myapp PRIVATE notcurses::notcurses)
Also, added the same CMake configuration for `Notcurses++`, to be used
in the following way:
find_package(Notcurses REQUIRED
find_package(Notcurses++ REQUIRED)
...
target_link_libraries(myapp PRIVATE notcurses++::notcurses++)
Docs:
`notcurses_cell(3)`: `cell_styles_{on,off} -> cell_{on,off}_styles`
and `cell_load_simple` -> `cell_load_char`
C++ API:
* Plane: added constructors taking `ncplane_options const&` instead of
the multitude of individual parameters
* Plane: drop `struct` when `ncplane_options` is used.
* Plane: added `strdup` (`cell_strdup`)
* Plane: added `extract` (`cell_extract`)
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()
* use ioctl(KDGETMODE) to detect Linux console
* diagnostic on KDGETMODE
* add logdebug()
* unit test for notcurses_drop_planes(), add ncplane_putnstr_aligned()
* linuxconsole PoC
* linuxconsole: dump unicode->font table
* linuxconsole: explode glyphs
* linuxconsole: show 7 glyphs per 'line'
* linuxconjammer: shim console font with half blocks
* signals: handler for SIGTERM
* man pages: update notcurses_init() for options
* add NCOPTION_NO_FONT_CHANGES #201
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.
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.
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
