⌨️ Real-time Typing

Enable real-time transliteration as users type character by character.

from lipilekhika.typing import create_typing_context

ctx = create_typing_context('Telugu')

# Process each character
for char in "namaste":
    diff = ctx.take_key_input(char)
    # Apply the diff to your text buffer:
    # - Remove diff.to_delete_chars_count characters
    # - Add diff.diff_add_text

API

create_typing_context(script, options=None) — Create a typing context

from lipilekhika.typing import create_typing_context, TypingContextOptions

options = TypingContextOptions(
    auto_context_clear_time_ms=4500,
    use_native_numerals=True,
    include_inherent_vowel=False
)

ctx = create_typing_context('Devanagari', options)

Returns: TypingContext with:

• take_key_input(char: str) -> TypingDiff — Process character input and return diff
• clear_context() — Clear internal state
• update_use_native_numerals(value: bool) — Update numeral preference
• update_include_inherent_vowel(value: bool) — Update inherent vowel inclusion
