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.
notcurses_stats() and notcurses_stats_reset() now take the
new statlock member, as do stat modifications from render,
raster, writeout, resize, plane creation, and plane
destruction. Add nonnull attributes to stats API. Initialize
and destroy statlock as part of notcurses struct. Update
documentation. Free pilelock on error paths. Closes#1139.
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.
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.
Add a new member 'sextants' to the terminfo cache (both
notcurses and ncvisual contain one of these, and both
initialize it the same way -- interrogate_terminfo()).
Add a new function, 'notcurses_media_defblitter()', and
deprecate 'ncvisual_default_blitter()' (the latter didn't
receive enough information to return NCBLIT_3x2). Update
all callers. Add new *internal* function rgba_default_blitter(),
so this logic can be freely changed in the future. If
sextants are available, and we're scaling, return NCBLIT_3x2.
Once we detect sextant availability, we'll have sexblitter
as a default -- stay tuned! #1114
- Disambiguate the docs for ncplane_erase()
