Syntax & Basic Types

Comments

Data Types

• Numbers: Integers (10) and Floating-point (3.14).
• Strings: Double-quoted text ("Hello").
• Booleans: true and false.
• Arrays: Ordered lists ([1, 2, 3]).
• Maps: Key-value pairs ({key : value}).
• Structs: User-defined complex objects.
• Date: Built-in simple date structure.
• Null: Represents missing value.

Variables & Constants

# Variables
x = 10;

# Constants
constant PI = 3.14;
    

Scope & Visibility

Fahrenheit uses block scoping. Modifiers control visibility:

• global: Accessible everywhere.
• local (default): Local to script execution.
• private, protected: For structure fields/methods.

Operators

Standard arithmetic (+, -, *, /, %), comparison (==, !=, >, <, >=, <=), and logical (&&, ||, !) operators are supported.

Compound Assignment: +=, -=, *=, /=

Ternary Operator: condition ? val1 : val2

Strings

Interpolation: "Hello ${name}!"

Multiline: Use triple quotes """ or '''. Multiline strings preserve whitespaces and newlines.

Enumerations

Use the enumerated keyword for fixed sets of constants.

enumerated Status { PENDING, ACTIVE, INACTIVE }

status = Status.ACTIVE;
if (status == Status.ACTIVE) {
    print("User is active");
}
    

Control Flow

If-Else

if (x > 5) {
    print("High");
} else {
    print("Low");
}
    

Loops

# While
while (i < 5) { i = i + 1; }

# For
for (i = 0; i < 10; i++) { print(i); }

# Foreach (Arrays & Strings)
foreach (item : list) { print(item); }
    

Switch

switch (val) {
    case 1: print("One"); break;
    default: print("Other");
}
    

Exception Handling

try {
    throw "Error";
} catch (e) {
    print("Caught: " + e);
} finally {
    print("Cleanup");
}
