Prompt Variables
Variables are a convenience feature that allows you to reuse part of a prompt without having to repeat yourself. It is a prompt element that allows part of a prompt to be stored under a label.
Here is how you define a variable:
$label_name = here is my prompt!
The following section will cover how to use them.
To use it in your prompt, just write a dollar sign $ followed by the variable name. (Note that you HAVE to define the variable before using it in your prompt!) For instance:
$cat = cat, fluffy, striped fur
very cute $cat
This will be translated into:
very cute cat, fluffy, striped fur
Here is another example:
$subject = a man
$color = blue
superb picture of $subject wearing a $color jacket and $color jeans
This will be translated into:
superb picture of a man wearing a blue jacket and blue jeans
You can nest prompt variable definitions into one another, like so:
$head_description = black hair, sunglasses,
$outfit_description = green coat, white fancy necklace,
$subject = $head_description $outfit_description
$subject
This translates to:
black hair, sunglasses, green coat, white fancy necklace,
If you want to define a prompt variable as a prompt that has more than one line, you can add a weight of 1 around it, like so:
$cool_prompt_on_multiple_lines = (
chimpanzee,
wearing a necktie,
dancing,
:1)
You can also define functions. For example:
$f($a, $b) = Hello M. $a, I am $b.
$f(Frank, Dan)
$f(Dan, Frank)
The above example is equivalent to:
Hello M. Frank, I am Dan.
Hello M. Dan, I am Frank.
Weight variables are just normal variables but you can also put them in places where weights are expected. For example:
$tree_weight = 1.3
a gigantic sparkling (christmas tree:$tree_weight),
in the middle of times squares,
golden hour, busy hour,
(christmas tree balls:$tree_weight),
massive crowd of pedestrians
Step index variables are just normal variables but you can also put them in places where step indices are expected. For example:
$begin = 7
$end = 13
a supersonic [rocket:starship: $begin, $end] flying in the night sky,
leaving behind [:a: $begin, $end] supersonic [boost fire:gas trail: $begin, $end]
