## Differences from Curses
The biggest difference, of course, is that Notcurses is not an implementation
of X/Open (aka XSI) Curses, nor part of SUS4-2018.
The detailed differences between Notcurses and NCURSES probably can't be fully
enumerated, and if they could, no one would want to read them. With that said,
some design decisions might surprise NCURSES programmers:

* It is an error in NCURSES to print to the bottommost, rightmost coordinate of
the screen when scrolling is disabled (because the cursor cannot be advanced).
Failure to advance the cursor does not result in an error in Notcurses (but
attempting to print at the cursor when it has been advanced off the plane
*does*).
### Features missing relative to NCURSES
This isn't "features currently missing", but rather "features I do not intend
to implement".
* There is no support for soft labels (`slk_init()`, etc.).
* There is no concept of subwindows which share memory with their parents.
* There is no tracing functionality ala `trace(3NCURSES)`. Superior external
tracing solutions exist, such as `bpftrace`.

the mailing list archives.

I get into contact with Thomas E. Dickey and confirm that what I'm hoping
to do doesn't really fit in with the codified Curses API.
* 2019-11-16: I make the [first commit](https://github.com/dankamongmen/notcurses/commit/635d7039d79e4f94ba645e8cb601e3a6d82a6b30)
to Notcurses.
* September 2019: I extracted fade routines from Growlight and Omphalos, and
offered them to NCURSES as extensions. They are not accepted, which is
understandable. I mention that I intend to extract ncreels, and offer to
include them in the CDK (Curses Development Kit). [Growlight issue #43](https://github.com/dankamongmen/growlight/issues/43)
is created regarding this extraction. A few minor patches go into NCURSES.
* 2011, 2013: I develop [Growlight](https://github.com/dankamongmen/growlight)
and [Omphalos](https://github.com/dankamongmen/omphalos), complicated TUIs
making extensive use of NCURSES.
### Thanks
* Notcurses could never be what it is without decades of tireless, likely
thankless work by Thomas E. Dickey on NCURSES. His FAQ is a model of
engineering history. He exemplifies documentation excellence and
conservative, thoughtful stewardship. The free software community owes
Mr. Dickey a great debt.
* Robert Edmonds provided tremendous assistance Debianizing the package,
and David Cantrell did likewise for Fedora. Both are hella engineers.
* Justine Tunney, one of my first friends at Google NYC, was always present
with support, and pointed out the useful memstream functionality of
POSIX, eliminating the need for me to cons up something similar.
* I one night read the entirety of Lexi Summer Hale's [essays](http://xn--rpa.cc/irl/index.html),
and began implementing her vision the next morning.
* NES art was lifted from [The Spriters Resource](https://www.spriters-resource.com/nes/)
and [NES Sprite](http://nes-sprite.resampled.ru/), the kind of sites that
make the Internet great. It probably violates any number of copyrights. C'est la vie.
* Mark Ferrari, master of the pixel, for no good reason allowed me to reproduce
his incredible and groundbreaking color-cycling artwork. Thanks Mark!
* The world map image was made by [Vecteezy](https://www.vecteezy.com/free-vector/world-map),
and is used according to the terms of their License.
* Finally, the [demoscene](https://en.wikipedia.org/wiki/Demoscene) and general
l33t scene of the 90s and early twenty-first century endlessly inspired a
young hax0r. There is great joy in computing; no one will drive us from
this paradise Turing has created!

* 2019-11-16: I make the [first commit](https://github.com/dankamongmen/notcurses/commit/635d7039d79e4f94ba645e8cb601e3a6d82a6b30)
to Notcurses.
* September 2019: I extracted fade routines from Growlight and Omphalos, and
offered them to NCURSES as extensions. They are not accepted, which is
understandable. I mention that I intend to extract ncreels, and offer to
include them in the CDK (Curses Development Kit). [Growlight issue #43](https://github.com/dankamongmen/growlight/issues/43)
is created regarding this extraction. A few minor patches go into NCURSES.
* 2011, 2013: I develop [Growlight](https://github.com/dankamongmen/growlight)
and [Omphalos](https://github.com/dankamongmen/omphalos), complicated TUIs
making extensive use of NCURSES.
# Thanks
* Notcurses could never be what it is without decades of tireless, likely
thankless work by Thomas E. Dickey on NCURSES. His FAQ is a model of
engineering history. He exemplifies documentation excellence and
conservative, thoughtful stewardship. The free software community owes
Mr. Dickey a great debt.
* Robert Edmonds provided tremendous assistance Debianizing the package,
and David Cantrell did likewise for Fedora. Both are hella engineers.
* Justine Tunney, one of my first friends at Google NYC, was always present
with support, and pointed out the useful memstream functionality of
POSIX, eliminating the need for me to cons up something similar.
* I one night read the entirety of Lexi Summer Hale's [essays](http://xn--rpa.cc/irl/index.html),
and began implementing her vision the next morning.
* NES art was lifted from [The Spriters Resource](https://www.spriters-resource.com/nes/)
and [NES Sprite](http://nes-sprite.resampled.ru/), the kind of sites that
make the Internet great. It probably violates any number of copyrights. C'est la vie.
* Mark Ferrari, master of the pixel, for no good reason allowed me to reproduce
his incredible and groundbreaking color-cycling artwork. Thanks Mark!
* The world map image was made by [Vecteezy](https://www.vecteezy.com/free-vector/world-map),
and is used according to the terms of their License.
* Finally, the [demoscene](https://en.wikipedia.org/wiki/Demoscene) and general
l33t scene of the 90s and early twenty-first century endlessly inspired a
young hax0r. There is great joy in computing; no one will drive us from
this paradise Turing has created!
