commands reference
Before using this reference, it is important to know how to read the command's notation. Here is an example:
> say [options] {message}Below is the table for deciphering the command's notation,
| word | description |
|---|---|
> or xxxxx (at the start of the notation) |
> indicates that it should be executed on prompt or in buffer while xxxxx only can be executed in buffer. It shouldn't be typed together with the command when calling.
|
text |
A literal text. Just type it exactly. In the example, say is a literal text. |
[text] |
An optional text. You can either substitude or omit it when calling. Suffixing with ... ([text...]) means it accepts multiple words. In the example, [options] is an optional text. |
{text} |
A mandatory text. You need to substitude it with the value you want and cannot be omitted. Suffixing with ...({text...}) means it accepts multiple words. In the example, {message} is a mandatory text. |
> say [options] {message}Prints {message} to the screen.
Arguments:
[options] - A group of single-character options for defining the representation of {message}.
| single-character option | meaning |

R |
Bright red. |
M |
Bright magenta. |
Y |
Bright yellow. |
G |
Bright grey. |
w |

n |
New line after {message}. Number of new lines will be number of ns given. |
