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
- made const NotcursesOptions constructors.
- refactor Notcurses constructors to return NcResult.
- pass NotcursesOptions by value, since it's Copy.
- update tests.
- add helper modules for Notcurses & NcPlane.
- new initialization functions to be used in tests.
- BONUS:
- refactor NcDirect
- update examples.
- change Option return type for NcResult when appropriate.
- make NcDirect constructors return NcResult.
- rename NcError::new() to with_msg() and simplify new().
- refactor examples:
- rename direct-image.rs to direct-image-c.rs
- recreate using rust methods, as direct-image-rust.rs
- differentiate more throughly between both styles.
- remove the sys namespace on both examples.
We need to use Result<> to manage error flow,
at least on the methods API. This way it will
finally feel idiomatic Rust and more concise.
Also, we can't return a non Result from main.
- rename NcResult to NcIntResult.
- new NcError & NcResult types.
- new error![] macro to reduce boilerplate.
- change return type of NcDirect methods to NcResult.
- refactor several examples to return NcResult:
direct-cursor, poc-direct & poc-kittyzapper.
- BONUS: fix test not stopping notcurses context.
- update lib doc-comment.
- fix typo in readme.
Kitty conflates an RGB background specification that aligns
with the default background color with that actual background
color. This can result in translucent background when we're
expecting opaque ones. Detect kitty (strstr check of terminal
name for "kitty"), and if it's active, mark `bg_collides_default`
with the rgb of the default background color. For now, we assume
this to be (0,0,0), but we ought improve it by determining (or
setting, if that's impossible) the precise default bg color.
Closes#1117.
When the -t switch is provided to notcurses-view, its
floating-point argument is the number of seconds for
which we delay after showing an image. When this is used,
the standard "press any key to continue" prompt is not
displayed, and indeed keybindings are not honored. This
can be used for a slideshow, or just for fullscreen display
involving no user interaction. It does not apply in the
case of -L for looping. Closes#1229.
