lipimala for Dart #

IAST-style transliteration for Devanagari and Gujarati, with canonical reverse conversion, direct script conversion, and Plain-English or Hunterian output.

Install #

dart pub add lipimala

Requires Dart 3.0 or newer.

Use #

import 'package:lipimala/lipimala.dart';

void main() {
  print('Kṛṣṇa'.toDevanagariFromIast()); // कृष्ण
  print('કૃષ્ણ'.toCanonicalIastFromGujarati()); // kṛṣṇa
  print('कानपुर'.toPlainEnglishFromDevanagari()); // kaanpur
  print('આજ મારે'.toPlainEnglishFromGujarati()); // aaj maare
  print('कृष्ण'.toCanonicalGujaratiFromDevanagari()); // કૃષ્ણ
}

Use toHunterianFromDevanagari() and toHunterianFromGujarati() for simplified ASCII Hunterian: one letter per long vowel and no consonant dots. That is the map and signboard spelling, not the 1954 macron form (jān). See the API reference. List extensions such as toDevanagariFromIast() also work on List<String>.

Profiles and options #

Forward conversion accepts strictIast, iso15919Core, or extendedIndic profiles. The default is extendedIndic. Options control normalization, unknown input, digits, punctuation, Vedic accents, whitespace, and exact-source metadata.

Direct Devanagari and Gujarati reading accepts BrahmicPlainEnglishOptions. Defaults stay the 1.1 output. 1.2.0 adds an opt-in natural reading. Examples are in the API reference.

Preserve the original input #

The rendered script may not encode the original Latin spelling, capitalization, or normalization. A result envelope keeps the original alongside the rendered value:

final result = 'Kṛṣṇa'.toDevanagari();
print(result.rendered);          // कृष्ण
print(result.restoreOriginal()); // Kṛṣṇa

For a standalone string, set embedExactSourceMetadata: true in the conversion options and use an exact reverse method such as toExactIastFromDevanagari(). Unicode-tag metadata can be removed by systems that sanitize invisible characters.
