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()
Add back the USE_DOCTEST CMake option, but make it conditional
upon BUILD_TESTING. If BUILD_TESTING is provided without
USE_DOCTEST, we build and run the PoC tests, just not
notcurses-tester. If neither is defined, no tests are available
(the PoC binaries are still built). If both are defined, build
the PoCs plus notcurses-tester, and run them all in make test.
This represents an essentially complete rewrite of ncvisual and associated code. It had two major goals:
Improve the ncvisual API based off lessons learned, pursuant to the upcoming API freeze. In particular, I wanted to:
decouple ncvisuals from ncplanes. It should be possible to render a ncvisual to multiple planes, with different scaling each time. It should be possible to create an ncvisual without a plane, etc.
normalize the various ways of constructing an ncvisual -- file, memory, plane, etc.
Support multiple blitters, from 7-bit ASCII to Sixel. This required writing the blitters in several cases, and they're not yet in their final implementations (but the API is fine)
I have not yet unified Plots and Visuals, and might not, given that the Plot code works fine. We could at this point implement Plots in terms of Visuals, though -- the blitter backend range has been unified. Sixel is not yet implemented, though it is listed.
There is a new POC tool, blitter. It renders its arguments using all possible blitter+scaling combinations. Another new POC, resize, displays its argument, then resizes it to the screen size and displays that, explicitly making use of ncvisual_resize() rather than a scaling parameter to ncvisual_render().
This also eliminates some memory leaks and bugs we were seeing in trunk, and brings in Sixel scaffolding.
The C++ wrapper will also need patching back up; I cut most of it down while wrestling with this crap, urk.
Closes#638, #562, and #622.
* ncplane_at_* and ncplane_at_cursor_*
We had notcurses_at_yx() expanding into three distinct parts of
the cell structure, and ncplane_at_yx() / ncplane_at_cursor()
writing directly to a cell. It was annoying to remember which
was which. The latter two now have a signature matching
notcurses_at_yx(), while the old functionality has been moved
to ncplane_at_yx_cell() and ncplane_at_cursor_yx(). #476
* packaging: s/libtinfo/Terminfo/g
* rust: add stddim_yx()
* rust: check for valid init in unit tests
* rust: serialize up tests
* constify notcurses_term_dim_yx()
* rust: add dim wrappers
* remove notcurses_resize() from public API #367
* call notcurses_resize() from notcurses_refresh() #367
