Variables

• Types

  • Integer: a positive or negative whole number capable of being represented with 32 bits.
  • Booleans: the keywords true and false with their respective meaning.

• Declaration (can only be done once)

  • <variable name 1>::Int: Declares an Integer value.

  • <variable name 2>::Bool: Declares a Boolean value.

  • <variable name 3>::Array{Int}(<size>): Declares a Integer array of size <size>.

  • <variable name 4>::Array{Bool}(<size>): Declares a Boolean array of size <size>.

  • <variable name 1>::Int = <Integer or Boolean>: Declares and initializes an Integer value.

  • <variable name 2>::Bool = <Boolean>: Declares and initializes an Boolean value.

  • <variable name 3>::Array{Int} = [<value-1\>, <value-2\>, <value-n\>]: Declares a Integer array of size n.

  • <variable name 4>::Array{Bool} = [<value-1\>, <value-2\>, <value-n\>]: Declares a Boolean array of size n.

• Usage

  • <variable name 1> : Gets the Integer value.

  • <variable name 2> : Gets the Boolean value.

  • <variable name 3>[<offset>] : Gets the Integer value at offset <offset>; Index starts from 1.

  • <variable name 4>[<offset>] : Gets the Boolean value at offset <offset>; Index starts from 1.

  • <variable name 1> = <Integer or Boolean>: Sets the Integer value.

  • <variable name 2> = <Boolean>: Sets the Boolean value.

  • <variable name 3>[<offset>] : Sets the Integer value at offset <offset>; Index starts from 1.

  • <variable name 4>[<offset>] : Sets the Boolean value at offset <offset>; Index starts from 1.

Comments

• Variants

  • #: single line comment. Ends when reaching new line or end of file.
  • #= <comment> =#: multiline comment. Comment between start symbol(#=) and end symbol (=#)

Printing

• Instructions

  • print: prints parameters
  • println: prints parameters and new line at the end

• Parameters (separaed by comas)

  • Literal: a string literal encapsulated by double quoutes, may contain escape characters. For example: "Hello World!".

    • Escape characters:

      • \\ : Adds a \ to the string
      • \" : Adds a " to the string
      • \t : Adds a tabulation to the string
      • \n : Adds a new line to the string
  • Integers: any expression resulting in an integer.
  • Booleans: any expression resulting in a boolean.

Expressions

• Operators

  • + : Addition
  • - : Subtraction
  • * : Multiplication
  • / : Division
  • % : Modularization
  • ^ : Exponentiation

• Usage

  • <Integer or Boolean Value> <Operator> <Integer or Boolean Value> : Returns result of operation

• Type

  • Any operation will result in an Integer

Conditions

• Binary Operators

  • > : Greater than
  • < : Less than
  • == : Equal to
  • >= : Greater than or Equal to
  • <= : Less than or Equal to
  • != : Not Equal to

• Binary Operators Usage

  • <Integer or Boolean Value> <Operator> <Integer or Boolean Value> : Returns result of operation

• Unary Operators

  • ! : Negation of

• Unary Operators Usage

  • <Operator> <Boolean Value> : Returns result of operation

• Type

  • Any operation will result in a Boolean

Bitwise Operations

• Binary Operators

  • | : OR
  • & : AND
  • $ : XOR
  • << : Arithmetic Shift Left
  • >> : Arithmetic Shift Right
  • >>> : Logical Shift Right

• Binary Operators Usage

  • <Integer or Boolean Value> <Operator> <Integer or Boolean Value> : Returns result of operation

• Uniary Operators

  • ~ : NOT

• Uniary Operators Usage

  • <Operator> <Integer or Boolean Value> : Returns the false if true and true if false.

• Type

  • | : Boolean if both values are boolean, else Integer
  • & : Boolean if both values are boolean, else Integer
  • $ : Boolean if both values are boolean, else Integer
  • << : Integer
  • >> : Integer
  • >>> : Integer
  • ~ : Boolean if value is boolean, else Integer

If Statement

• Usage

  • if <condition> <statements> elseif <condition> <statements> else <statements> end

• Notes

  • if must be first
  • elseif and else sentences are optional
  • if there is an else it must be last
  • executes code if condition is true
  • conditionals can only be of type Boolean
