2. Language Features

2.1 Print Statements (say)

say "Hello, world!"
say x

• Syntax: say <expression>
• Prints the value of the expression to the console.

2.2 Variable Declarations (let)

let count be 42
let name be "Alice"
let value be count

• Syntax: let <identifier> [be= <expression>]
• Declares a variable, optionally with a value and type.

2.3 Functions (define)

define function sayName(name):
  say "Hello, "
  say name

call sayName("Novascript")

• Syntax: define function <function-name> [with <param> as <type>, ...]:
• Defines a function.

2.4 Conditionals (when,otherwise)

let age be 18
when age<18 then
    say "You can't vote"
otherwise
    say "You can vote"
end

• Syntax:

  • when <condition> then
  • otherwise

2.5 Loops (while, for)

repeat while a<10
    say a
    set a to a+1
end

#for
repeat for j from 1 to 5
    say j
end

• Syntax:

  • repeat while <condition>
  • repeat for <variable> from <start> to <end>:

4. Examples

Factorial

define function factorial(n)
  let result be 1
  let i be 1

  repeat while i<=n
    set result to result*i
    set i to i+1
  end

  return result
end

let answer be call factorial(5)
say answer

Fibonacci

define function fibonacci(n)
  let a be 0
  let b be 1
  let c be 0

  repeat while c<n
    say a
    let temp be b
    set b to a+b
    set a to temp
    set c to c+1
  end
end

call fibonacci(10)

Exception Handling

try
  let number be 0
  let result be 100/number
  say result
catch error
  say "an error occured:"
  say error
end

5. File Execution

Save code in a .ns file and run:

g++ -I../include -o main main.cpp lexer.cpp Parser.cpp SymbolTable.cpp SemanticAnalyzer.cpp -std=c++17 -mconsole

After successful compilation - run:

./main

Bam! You just experienced Novascript!
