(This is a fun project) used to demonstrate how interpreters work.

🍷 Sintaxe

meow("Hello World!") # print "Hello world!" in the console

pspsps add (x, y)  { # define add function
  x + y # return 15
}
meow(add(10, 5)) # print 15

General

• in catscript, the # symbol is used to comment a line
• catscript is case-sensitive
• catscript is whitespace-insensitive
• catscript is a dynamically typed language
• return values are implicit

Arithmetic operators

• +: Addition
• -: Subtraction
• *: Multiplication
• /: Division
• %: Modulus

Types

catscript is a dynamically typed language, so you don't need to specify the type of a variable. The interpreter will infer the type based on the value assigned to it.

• string: A sequence of characters
• number: A numeric value
• boolean: A logical value
• Object: A collection of key-value pairs

Native functions

• meow(): Print a message in the console
• timecat(): Get the current time in ms

Variables

To declare a variable, use the cat or staticat keyword followed by the variable name and the value.

cat name = "Pedro Luis"
staticat age = 16

cat variables are mutable, while staticat variables are immutable.

Important

in catscript, the ; symbol is only for declaration of variables and not is optional

Functions

To declare a function, use the pspsps keyword followed by the function name and the parameters.

pspsps add (x, y) {
  x + y # return
}

To call a function, use the function name followed by the parameters (if you have).

meow(add(10, 5)) # print 15

Important

In catscript, the return value is implicit. the last value of the function is returned

Objects

To declare an object, use the {} in cat keyword or staticat followed by the object name and the key-value pairs.

staticat obj = {
    name:"catscript",
    repo:"https://github.com/luiisp/catscript",
    author:{
        name: "Pedro Luis Dias",
        github: "https://github.com/luiisp/"
    },
    version:"lasted",
};
