Don't bias the nccell width by 1, or 0-length EGCs become
255 columns. We weren't actually using the width to drive
much anything until now, so this wasn't a problem, but it
is exposed as an error once we got rid of CELL_WIDE_ASIAN
and start looping through the actual egc column width.
Closes#1278, closes#1277
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.
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
Thread out ncls to perform the media decode in different threads, in parallel. Only the display needs be locked. On a directory of 200 files on my 39070X, this speeds ncls from ~5s to ~1s. On 75 files, we go from ~.5s to ~.2s. On a single file, we lose about 5%. To facilitate this, ncdirect_render_image() has been split into two helpers, ncdirect_render_frame() and ncdirect_raster_frame().
Progress bars now support four 32-bit channels in ncprogbar_options, and uses them to color a gradient. The redraw procedure has been changed from O(n) to O(1). ASCII progress bars have been repaired. Closes#1213.
Some EGCs are more than 2 columns (wcwidth() never returns more than 2, so far as i can tell, but when multiple characters combine, we use the sum). An example would be ကြေ (Myanmar) which occupies three columns over the course of three characters. Track the width (biased by 1) in cell->width, taking over 8 bits from cell->reserved. Use this width in rasterization. Closes#1203.
- 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`)
Added:
* Pile: new class derived from Plane, which implements all the
`ncpile_*` calls
* Plane: `get_parent` (`ncplane_parent`)
* Plane: protected constructor for use by `Pile` (or other derived
classes which cannot provide a valid `ncplane*` when invoking parent
constructor.
* Plane: `set_plane` for use by the derived classes above.
Changed:
* Plane: `to_ncplane` is a `const` method now.
Fixes: https://github.com/dankamongmen/notcurses/issues/1009
Whenever a widget is created with its `*_create` function it currently
claims full ownership of the passed panel, including its destruction.
However, the C++ wrapper around the panel is not aware of this and will
attempt to destroy the native panel in the destructor, leading to
segfaults.
Fix this by introduction of a `Widget` class which contains the logic to
properly modify the `Panel` instance to not double-destroy the native
panel. The solution is a bit fragile since the `Panel` instance is left
intact (we can't free it for the user) in a state that's safe for the
C++ wrapper, but calling any C function via the wrapper **will** pass a
`NULL` pointer in the panel argument - therefore the C functions MUST be
proofed against this. The proofing belongs in the C backend code since
this protects also C and other language binding users from such abuse.
The Widget class will first verify that the passed `Plane` instance
hasn't already been "disowned" and will throw an exception to the effect
if it was. Next, it will proceed to take over ownership of the native
panel instance and mark the passed `Panel` as "invalid" (i.e. not owning
any native panel instance anymore)
The above changes require modification of `Panel` instances and so all
the widget constructors taking `const*` or `const&` have been removed
from widget classes.
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.
Maybe the type may reflect that it's not supposed to be a long now.
Although for what I've learnt about C, in practice it will probably still be a long. And I can't be sure whether in some platforms where it will indeed be a short the code will keep compiling, so maybe it's safer just to remove the outdated comment, or whatever you decide.
I'm just finding things while I work in the bindings =) And I was surprised to learn about the little guarantees C gives regarding the types sizes...
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
* The zoo demo made manifest that we had some serious problems handling sequences of longer lines in ncplane_puttext(). This remedies most of the problems, though it's not yet perfect. #871
* Guard notcurses* for NULL in log*() #878#879
* Fix memory leak in ncdirect_dump_plane()
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()
