Quick Start

from hangul_keyboard import convert_roman_to_hangul, decompose_hangul_full, decompose_hangul_str

# Basic usage
result = convert_roman_to_hangul("dkssud")
print(result)  # Output: "한글"

# Already Hangul - returns as-is
result = convert_roman_to_hangul("한글")
print(result)  # Output: "한글"

# Mixed with numbers and special characters
result = convert_roman_to_hangul("rk123!")
print(result)  # Output: "가123!"

# Decompose into jamo list (full)
jamo_list = decompose_hangul_full("한글")
print(jamo_list)  # Output: ['ㅎ', 'ㅏ', 'ㄴ', 'ㄱ', 'ㅡ', 'ㄹ']

# Decompose into jamo string
jamo_str = decompose_hangul_str("한글")
print(jamo_str)  # Output: "ㅎㅏㄴㄱㅡㄹ"
