# 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 24bpp TrueColor RGB environment. If
|
|
|
**notcurses-demo** seems to generate garbage, something is likely configured in
|
|
|
a way that is going to prevent notcurses from working.

At any time, press 'q' to quit. The demo is best run in at least an 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 (log level 8) or nothing (log level 0) to stderr.
|
|
|
|
|
|
**-f renderfile**: Render each frame to **renderfile** in addition to the screen.
|
|
|
|
|
|
**-J jsonfile**: Emit JSON summary of run to **jsonfile**.
|
|
|
|
|
|
**-m margins**: Define rendering margins (see below).
|
|
|
|
|
|
**-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.
|
|
|
|
|
|
**-i**: Continue after a failing demo.
|
|
|
|
|
|
**-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 **ixezydthnbcmgarwuvlsfjqo**. See above for a list of demos.
|
|
|
|
|
|
Default margins are all 0, and thus the full screen will be rendered. Using
|
|
|
**-m**, margins can be supplied. Provide a single number to set all four margins
|
|
|
to the same value, or four comma-delimited values for the top, right, bottom,
|
|
|
and left margins respectively. Negative margins are illegal.
|
|
|
|
|
|
# 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 RGB escapes),
|
|
|
* A monospaced font, and
|
|
|
* Good Unicode support in your libc, font, and terminal emulator.
|
|
|
|
|
|
The Debian version of notcurses leaves out certain multimedia considered
|
|
|
non-free under the Debian Free Software Guidelines. As a result, the
|
|
|
**chunli**, **eagle**, **jungle**, **luigi**, and **view** demos
|
|
|
are unavailable through the Debian package. This applies to any distro
|
|
|
which uses the DFSG source tarball, including Ubuntu and Fedora.
|
|
|
|
|
|
If notcurses is built without multimedia support, the **chunli**, **eagle**,
|
|
|
**outro**, **view**, **xray**, and **yield** demos will be partially or wholly
|
|
|
unavailable. If notcurses is built without libqrcodegen, the **qrcode** demo
|
|
|
will be unavailable.
|
|
|
|
|
|
If **notcurses-demo** is run in a terminal lacking the **can_change** terminfo
|
|
|
capability, **jungle** will be skipped.
|
|
|
|
|
|
The following keypresses are recognized (and are also available from the menu):
|
|
|
|
|
|
* **Ctrl-U**: Toggle the help screen.
|
|
|
* **H**: Toggle the HUD. The HUD shows the most recent and current demos'
|
|
|
runtime and number of rendered frames. It can be grabbed and moved
|
|
|
with the mouse.
|
|
|
* **Ctrl-R**: Restart the demo.
|
|
|
* **q**: Quit.
