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.

This document attempts to list user-visible changes and any major internal

|
rearrangements of Notcurse.
|
|
|
|
* 1.2.5 (not yet released)
|
|
** `ncvisual_render()` now returns the number of cells emitted on success, as
|
|
opposed to 0. Failure still sees -1 returned.
|
|
** `ncvisual_render()` now interprets length parameters of -1 to mean "to the
|
|
end along this axis", and no longer interprets 0 to mean this. 0 now means
|
|
"a length of 0", resulting in a zero-area rendering.
|
|
** `notcurses_at_yx()` no longer accepts a `cell*` as its last parameter.
|
|
Instead, it accepts a `uint32_t*` and a `uint64_t*`, and writes the
|
|
attribute and channels to these parameters. This was done because the
|
|
`gcluster` field of the `cell*` was always set to 0, which was surprising
|
|
and a source of blunders. The EGC is returned via the `char*` return
|
|
value. https://github.com/dankamongmen/notcurses/issues/410

|
|
|
* 1.2.4 2020-03-24
|
|
** Add ncmultiselector
|
|
** Add `ncdirect_cursor_enable()` and `ncdirect_cursor_disable()`.
