lavat 命令

常用示例

说明

lavat is a terminal program that simulates a lava lamp using metaballs rendered with text characters. Each metaball is a soft circular density field; overlapping fields blend smoothly, producing the characteristic blob-merging effect of a lava lamp directly inside the terminal. The program supports both standard 256-color mode and a true-color gradient mode (-g), plus an optional gravity model (-G) that periodically heats balls at the bottom of the display so they rise, cool at the top, and fall again. Colors, radius, speed, and the number of metaballs can be tuned from the command line or adjusted interactively while the animation runs. lavat is primarily used as a decorative screensaver-style toy or a visual backdrop in a spare terminal window. It is not a screen-locking utility and does not require an X session — it runs in any Unix terminal supported by its underlying Termbox2 rendering library.

参数

-c _color_

Metaball color. Accepts a named color or hex value (e.g. _red_, _00FF00_).

-k _color_

Rim color drawn around each metaball.

-g

Enable gradient/truecolor rendering (requires a truecolor-capable terminal).

-G

Enable gravity simulation. Metaballs heat at the bottom, rise, cool at the top, then fall.

-s _1-10_

Animation speed. Default is _5_.

-r _1-10_

Metaball radius. Default is _5_.

-R _1-5_

Rim thickness around each metaball.

-b _5-20_

Number of metaballs. Default is _10_.

-F _chars_

Custom character set used to render density levels.

-C

Confine metaballs inside the terminal bounds.

-p _p1_|_p2_|_p3_

Enable one of three preset party (color-cycling) modes.

-h

Print help and exit.
