# lavat
|
|
|
|
Little program that simulates a lava lamp in the terminal.
|
|
|
|
## Installation
|
|
|
|
Requirements: A Unix-like system, a C compiler and make.
|
|
|
|
```
|
|
git clone https://github.com/AngelJumbo/lavat
|
|
cd lavat
|
|
make install
|
|
```
|
|
|
|
### Arch Linux
|
|
Lavat is also available on the AUR [here](https://aur.archlinux.org/packages/lavat-git). Install it with your favourite AUR-helper or manually.
|
|
```
|
|
$ paru -S lavat-git
|
|
```
|
|
## Usage
|
|
|
|
```
|
|
Usage: lavaterm [OPTIONS]
|
|
OPTIONS:
|
|
-c COLOR Set color. Available colours: red, blue, yellow, green, cyan and magenta.
|
|
Besides those colors the default one is the normal foreground of your terminal.
|
|
-s SPEED Set the speed, from 1 to 5. (default 1)
|
|
-r RADIUS Set the radius of the metaballs, from 1 to 10. (default: 5)
|
|
-R RIM Set a "rim" for each metaball, sizes from 1 to 5. (default: none)
|
|
This option does not work with the default color
|
|
-b NBALLS Set the number of metaballs in the simulation, from 2 to 20. (default: 10)
|
|
-F CHARS Allows for a custom set of chars to be used
|
|
-h Print help.
|
|
```
|
|
|
|
## Demo
|
|
|
|
`lavat -c red -R 1`
|
|
|
|
|
|
|
|
|
|
`lavat -c cyan -R 4 -b 20 -r 2`
|
|
|
|
|
|
|
|
If you send more than one character to the -F option you can have 3d-ish effect.
|
|
|
|
`lavat -c blue -R2 -F @:::::: -r10`
|
|
|
|
|
|
|
|
(The colors depend on your terminal color scheme.)
