* 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
Fill-type functions used to return 0 for success, and -1
on failure. They now return the number of cells written
on success, similarly to ncvisual_render(). Resolves#427.
Resolves#410. notcurses_at_yx() accepted a cell*, but the
gcluster of this cell was always set to 0. The EGC is instead
a heap-allocated copy, returned as the primary return value.
This is due to the absence of an egcpool to bind against.
Existing callers can be converted thus:
* instead of passing cell 'c', pass &(c)->attrword, &(c)->channels
* either initialize 'c' with CELL_TRIVIAL_INITIALIZER, or set its
gcluster field to 0 following the call
I've updated all calls from tests/demos, updated the docs, and
updated the C++ and Python wrappers.
Add ncplane_bound(3). This allows a new plane N to be created in the
*bound* state relative to another ncplane B. If B moves, N moves the
same amount. If N is moved, the coordinates are taken relative to B
as opposed to the standard plane. If B is destroyed, N is destroyed.
Each plane can have many planes bound to it, but can only be bound to
a single plane. Add ncplane_reparent(3). This allows a plane to be
detached from any plane to which it is bound, and optionally rebound
to a new plane. The standard plane cannot be reparented.
Documentation and unit tests have been added for both.
* tetris: use NES gravities
* tetris: use NES grav multiplier of 50ms
* tetris: implement move down #421
* README: mention notcurses-tetris #421
* tetris: use double box for boundary #421
* tetris: extract background.h
* tetris: break up into chunks suitable for book
* tetris: do the rotations
ncplane_mergedown() is similar to the "Merge down" operation
in the GIMP. It writes to the destination plane the result
of rendering the source and destination frames per se.
Add four new fields to notcurses_options: margin_{tblr}, which requests margins to the top, right, bottom, and left. Render only within those margins, leaving the screen otherwise untouched (well, cleared if using the alternate screen). #293
* CMake: add USE_PANDOC, USE_DOXYGEN options #101
* README: mention rust
* start integrating rust into build #101
* CMake: add USE_NETWORK option for cargo
* Debian: build-dep on doxygen
* rust: colloquy checks in Cargo.lock
* extract NCKEY defines into their own include
* colloquy: use clap to parse CLI args
* CMake: unify option namespace
* Python: update include path
* Rust: fix up --frozen workings for -DUSE_NETWORK=off
* CMake: abstract out colloquy a little
* Sync direct.hh to the New Way
