Syntax of SRON

A scope of a SRON's code starts with a function and it is started with an open curly brace '{' and ended with a close curly brace '}'. Almost all instructions inside a function are written in the below format:

    attribute : statement

Attribute defines the types of statement and is used to tell the compiler that this statement is written with XYZ intention. There are many attributes provides in SRON:

1) name : this attribute is used to declare a function name.

{
    name : function_name
}

---

2) args : this attribute is used to declare a function arguments.

{
    name : fnc
    args : (Int a, String b)
}

{
    name : MAIN
    args : (List arglist)
}

---

3) console : this attribute is used to print values on the terminal/command line.

{
    name : MAIN
    console : ("Hello, World!")
}

---

4) type : this attribute is used to set the return type of the function

{
    name : get_int
    type : Int
    return : 27062003
}

---

5) return : this attribute is used to return a value from a function

{
    name : get_pi
    return : PI
}

---

6) for : this attribute is used to declare a for-loop.

{
    name : MAIN
    for : {
        range : (Int i = 0, 5)
        console : ( i , '\n')
    }
}

---

7) range : this attribute is used to declare the range of for-loop.

{
    name : MAIN
    for : {
        range : (Int i = 0, 10 , 2)
        console : ( i , '\n' )
    }
}

---

8) while : this attribute is used to declare a while loop.

{
    name : MAIN
    while : {
        condition : true
        console : ( "SRON\n" )
    }
}

---

9) condition : this attribute is used to check if the given condition is true or false. This attribute is used with 'while', 'if' and 'elif' attributes.

{
    name : MAIN
    while : {
        condition : false
        @ the statement of condition attribute only requires a 'Bool' type value.
    }
}

---

10) if : this attribute is used to declare a if statement.

{
    name : MAIN
    Any val = 10
    if : {
        @ the integer value can be converted to boolean type value
        condition : val
        println(val)   
    }
}

---

11) elif : this attribute is used to declare an elif statement.

{
    name : MAIN
    Int val = 9
    if : {
        condition : ~{ val%2 == 0 }~
        println("Even")
    }
    elif : {
        condition : ~{ val%3 == 0 }~
        @ the control flow will come here only if the code within the 'if'
        @ attribute will not be executed.
        println("Divisible by Three")
    }
}

---

12) else : this attribute is used to declare a else statement.

{
    name : MAIN
    variables : Int val = 7
    if : {
        condition : ~{ val%2 == 0 }~
        println("Even")
        
    }
    else : {
        println("Odd")
        @ this statement will execute only if the above 
        @ if-attribute is not executed.
    }
}

---

13) foreach : this attribute is used to iterate linearly over String or List.

{
    name : main
    
    foreach : {
        @ 'on' attribute is used to specify on what value
        @ will the foreach will iterate with what variable
        on : Any val, [1,2,3,4,5]
        println(val)
    }
}

14) rotate : this attribute is used to rotate value or swap value.

{
    name : main
    
    Int val1 = 91
    Double val2 = 1001.27112
    String val3 = "SRON"
    
    console : (val1, ' ', val2 , ' ' , val3)
    
    rotate : (val1 , val2, val3)
    
    console : (val1, ' ', val2 , ' ' , val3)
}
