Variables (vars) are places in memory when we store a values
Variables in Green Tea are represented by a dollar sign followed by the name of the variable. The variable name is case-sensitive.
Variable names follow the same rules as other labels in GreenTea. A valid variable name starts with a letter or underscore, followed by any number of letters, numbers, or underscores. As a regular expression, it would be expressed thus: ^[a-zA-Z_\x80-\xff][a-zA-Z0-9_\x80-\xff]*$
Ex: $var_name
Assignment
Put a value into a var
$var:<value>
Ex:
$name:John
$age:24
Or assigning multiple vars at ocne:
$name,$age: John, 24
Get value
To get a variable’s value, use it’s name:
$name:John
$name
> John
Scope
A variable defined in a function only usable in that function.
If you want to access global variables inside function, use $$ instead of $
$a=0
@function
$b: 1
$$c: 2
@echo $a // error
@echo $$a // output: 0
@echo $b // error
@echo $c // output: 2
