Literally translated \u2013 not curses. It is written in C, using C++-safe headers. Wrappers for <a rel=\"nofollow\" href=\"https:\/\/crates.io\/crates\/notcurses\">Rust<\/a>, <a rel=\"nofollow\" href=\"https:\/\/github.com\/dankamongmen\/notcurses\/issues\/212\">C++<\/a> and <a rel=\"nofollow\" href=\"https:\/\/pypi.org\/project\/notcurses\">Python<\/a>.<\/p>\n<p><\/noindex><\/noindex><\/p>\n<p>What it is: a library that simplifies complex TUIs on modern terminal emulators, maximally supporting bright colors and Unicode. Many tasks delegated to curses can be accomplished with notcurses (and vice versa).<\/p>\n<p>What it is not: a compatible implementation of X\/Open curses or a replacement for ncurses on existing systems.<\/p>\n<p>Notcurses rejects the X\/Open Curses API provided as part of the Single UNIX Specification. This specification is outdated and, for example, does not support terminal functionalities like unindexed 24-bit color. As such, notcurses is not a replacement for curses. It is less portable and definitely tested on a smaller range of hardware.<br \/>\nWhere possible, notcurses uses the terminfo library provided with ncurses, leveraging its portability.<br \/>\nNotcurses opens up extended functionalities for user interaction on workstations, phones, laptops, and tablets.<\/p>\n<p>Why use this non-standard library?<\/p>\n<ul>\n<li>\n<p>Thread-safety and efficient usage in multithreaded programs was a design consideration from the outset.<\/p>\n<\/li>\n<li>\n<p>A better-designed API compared to X\/Open:<\/p>\n<ul>\n<li>\n<p>Exported identifiers have a prefix to avoid namespace collisions.<\/p>\n<\/li>\n<li>\n<p>The library's object file exports a minimal set of symbols. Where appropriate, static code is used only for lowercase headers. This facilitates compiler optimization and reduces load times.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<li>\n<noindex><\/p>\n<p>All APIs initially support a universal character set (Unicode). The character cell API is based on the concept of <a rel=\"nofollow\" href=\"https:\/\/unicode.org\/reports\/tr29\/\">Unicode\u2019s Extended Grapheme Cluster<\/a>.<\/p>\n<p><\/noindex>\n<\/li>\n<li>\n<p>Visual capabilities including images, fonts, videos, high-contrast text, sprites, and transparent areas. All APIs natively support 24-bit color, quantized as needed for the terminal.<\/p>\n<\/li>\n<li>\n<noindex><\/p>\n<p>Apache2 License, unlike <a rel=\"nofollow\" href=\"https:\/\/invisible-island.net\/ncurses\/ncurses-license.html\">the drama<\/a> in several acts, which is licensed under ncurses (the latest is summarized as \"MIT-X11 rephrased\").<\/p>\n<p><\/noindex>\n<\/li>\n<\/ul>\n<p>Since the previous significant release 1.1.0, a vast number of features have been added. Key changes:<\/p>\n<ul>\n<li>\n<p>A reading widget for inputting arbitrary form strings tied to reading strings.<\/p>\n<\/li>\n<li>\n<p>A subprocess widget for spawning a subprocess, controlling it, and streaming its results back.<\/p>\n<\/li>\n<li>\n<p>In Linux 5.3+, a new mechanism clone3+pidfd is used to manage processes without race conditions.<\/p>\n<\/li>\n<li>\n<p>The Fdplane widget for streaming arbitrary file descriptors to a plane (on which the subprocess is built). Both allow callbacks to style or otherwise process text.<\/p>\n<\/li>\n<li>\n<p>Rotation of planes and visual effects. Loading visualizations from memory. Arbitrary RGBA\/BGRx blitting.<\/p>\n<\/li>\n<li>\n<p>Menus can be placed on any (or both) of the top and bottom planes.<\/p>\n<\/li>\n<li>\n<p>Significant improvements in Direct mode.<\/p>\n<\/li>\n<li>\n<p>Polyfills, gradients, and high-contrast text.<\/p>\n<\/li>\n<li>\n<p>Tetris added as an example.<\/p>\n<\/li>\n<li>\n<p>C++ wrappers by Marek Habersack now have the ability to throw exceptions (if needed).<\/p>\n<\/li>\n<li>\n<p>Python and Rust FFI have been updated and tested.<\/p>\n<\/li>\n<\/ul>\n<p><a rel=\"nofollow\"
