Syntax Overview

Syntax Overview

Thagore uses Python-style indentation for blocks. Every block header ends with : and the body is indented with 2 spaces.

Key rules

• 2-space indentation — tabs are rejected, and indentation must be a multiple of 2 spaces
• No semicolons — each statement is one line
• Conditions require parentheses — if (x > 0): and while (x > 0):
• Comments use #
• File extension is .tg

Minimal program

func main() -> i32:
  println("Hello, Thagore!")
  return 0

Top-level forms

A source file contains top-level declarations only. There are no bare executable statements outside functions.

import std.math as math

const LIMIT: i32 = 10

struct Point:
  x: i32
  y: i32

func distance(point: Point) -> i32:
  return math.abs(point.x) + math.abs(point.y)

func main() -> i32:
  return 0

Syntax topics

• Print & Output — print, println, output to stdout and stderr
• Variables & let — let declarations, type inference, reassignment
• Functions — func, parameters, return types
• Control Flow — if/else, while, for, break, continue
• Structs & impl — struct definitions and methods
• FFI & Import — import, extern func
• Advanced Features — intent, flow, generics
• Reading Input — reading from stdin via std.io
