NAME

notcurses-demo - Show off some notcurses features

SYNOPSIS

notcurses-demo [-h|--help] [-p path] [-d delaymult] [-l loglevel] [-kHVc] demospec

DESCRIPTION

notcurses-demo demonstrates the capabilities of the notcurses library. It can be run in any terminal emulator or console with a correct terminfo(5) database, but is at is best in a "DirectColor" 24bpp RGB environment. If notcurses-demo seems to generate garbage, something is likely configured in a way that is going to prevent notcurses from working.

The demonstrations include:

(i)ntro—a setting of tone
(b)oxes—pulsating boxes with a transparent center
(c)hunli—the strongest woman in the world
(e)agle—they took some time off my life, back in the day
(f)allin'—the screen falls apart under heavy blows
(g)rid—a gradient of color lain atop a great grid
(j)ungle—low-bandwidth color cycling reveals ancient ruins
(l)uigi-a dashing Apennine plumber in a world of fire
(p)anelreels—demonstration of the panelreel high-level widget
(s)liders—a missing-piece puzzle made up of colorful blocks
(t)rans—an exploration of various transparencies
(u)niblocks—a series of blocks detailing Unicode pages
(v)iew—images and a video are rendered as text
(w)itherworm—a great Nothing slowly robs the world of color
(x)ray—stimulate a logo with energy
(o)utro—a message of hope from the library's author

At any time, press 'q' to quit. The demo is best run in at least a 80x45 terminal.

OPTIONS

-p path: Look in the specified path for data files.

-d delaymult: Apply a non-negative rational multiplier to the standard delay of 1s.

-l loglevel: Log everything (high log level) or nothing (log level 0) to stderr.

-H: Launch a HUD with running timers for each demo. This HUD can be moved or closed with the mouse.

-k: Inhibit use of the alternate screen. Necessary if you want the output left on your terminal after the program exits.

-c: Do not attempt to seed the PRNG. This is useful when benchmarking.

-h: Print a usage message, and exit with success.

-V: Print the program name and version, and exit with success.

demospec: Select which demos to run, and what order to run them in. The default is ixetbcgpwuvlfsjo. See above for a list of demos.

NOTES

Proper display requires:

A terminal advertising the rgb terminfo(5) capability, or that the environment variable COLORTERM is defined to 24bit (and that the terminal honors this variable),
A monospaced font, and
Good Unicode support in your libc, font, and terminal emulator.

BUGS

If notcurses is built without FFmpeg, the following demos will fail immedaitely when specified: xray, eagle, chunli, fallin', view, outro.
