Module:ur-translit

This module will transliterate Urdu language text per WT:UR TR. It is also used to transliterate Brahui and Gojri.
The module should preferably not be called directly from templates or other modules.
To use it from a template, use {{xlit}}.
Within a module, use Module:languages#Language:transliterate.
For testcases, see Module:ur-translit/testcases.
Functions
tr(text, lang, sc)- Transliterates a given piece of
textwritten in the script specified by the codesc, and language specified by the codelang. - When the transliteration fails, returns
nil.
Background
THIS WILL REQUIRE DIACRITICS (USED CORRECTLY), Diacritics can be found at http://udb.gov.pk (which is NOT always correct). This should work correctly for majority of the work, although is still in progress.
Read #Usage notes for tips on how to use the module correctly:
Usage notes
- All consonants must be paired to a vowel (a, i, u, ā, e, ī, o, ū) or a sukoon/jazm. Or else the module will return NIL (blank).
- Alif MUST be paired to either a consonant or a vowel, or the module will return NIL.
- Whenever there are two adjacent semivowels, the first semivowel will become the consonant and the second will be the vowel. To reverse that order, simply put a sukoon on the second semivowel.
- baṛī ye (e, ai) and choṭī ye (ī, y) are distinguished medically using diacritics. However in the final position choṭī ye is always -ī (since choṭī ye cannot be "y" in the final position), and a final baṛī ye defaults to -ē but can become -ai with a preceding zabar.
- If, for some reason, a final choṭī ye needs to be a "y", put a sukoon on it.
- baṛī ye (e, ai) and choṭī ye (ī, y) are distinguished medically using diacritics. However in the final position choṭī ye is always -ī (since choṭī ye cannot be "y" in the final position), and a final baṛī ye defaults to -ē but can become -ai with a preceding zabar.
- Noon ghunna ـن٘ـ/ـں generally represents a nasal vowel. The only exceptions being when a nasal vowel isn't possible (in Urdu), such as before b, bh, j, jh, g, gh, ḍh, dh, th, q (and before kh, ṭh, ṭ and ph, unless the nasal vowel is ā, ī, or ū). Since it is impossible for a nasal vowel to appear before these sounds, the module will return an assimilated nasal.
- If a nasal vowel is not desired, use a sukoon to return a regular noon.
- If ghunna is occurring after ā, ī, or ū but needs to assimilate with ph or kh, the assimilation must be manually entered. Since unlike all other vowels, ā, ī, and ū can actually be nasalized before these letters. For all consonants not mentioned, nasal assimilation can be predicted with only a jazm/sukoon (if it even occurs).
- Noon ghunna assimilating with "k" is not as common in Urdu as it is in Hindi, it mainly appears in english loanwords (and only at the end of a word). In which case the assimilation can be predicted with a sukoon/jazm. This assimilation should disappear if the word is inflected. Compare بَینْک (baiṅk) to بَین٘کوں (ba͠ikõ)
- The aspirate 'he' (i.e. do-chashme-he, ھ (h)) does NOT need ANY DIACRITICS in ANY CIRCUMSTANCES, all diacritics should either go on the previous letter or on the following letter.
- The module will work regardless but based on common practice putting a vowel on the aspirate ھ would be inappropriate.
- The Tashdeed/Shadda works with another diacritic, as well as alone
- The Sukoon/Jazm diacritic is required for consonant clusters, or else the module will return NIL
Updates
To do
require an initial alif to be paired to a vowel (either a diacritic or vao/ye).needed to prevent false positives- support for al- assimilation in Arabic loanwords.
- how will we distinguish an initial al- in non arabic words? This is probably impossible and might not happen.
DIFFERENCE BETWEEN ṇ, ṅ, ñ AND n .Detect when transliteration is needed and when not (i.e. if diacritics are present/needed or not)izafa/ezafe supportRevert the module to transliterate initial "ای" as 'ē'اَللہ = sort out ہ + khari zabar diacritictransliteration detection often gives false positives
Example
Test Urdu:
تَرْکِ تَعَلُقّات پِہ رویا نَہ تُو نَہ مَیں لیکِن یِہ کْیا کَہ چَین سے سویا نَہ تُو نَہ مَیں
وُہ ہَمْسَفَر تھا مَگَر اُس سے ہَمْنَوَائی نَہ تھی کَہ دُھوپ چھاؤں کا عالَم رَہا جُدائی نَہ تھی
عَداوَتیں تِھیں، تَغافُل تھا رَنْجِشیں تِھیں مَگَر بِچَھڑْنے والے میں سَب کُچھ تھا بے وَفائی نَہ تھی
کاجَل ڈالو کُرْکُرا سُرْمَہ سَہا نَہ جائے جِن نَین میں پِی بَسے دُوجا کَون سَمائے؟
بِچَھڑْتے وَقْت اُن آن٘کھوں میں
تھی ہَماری غَزَل
غَزَل تھی وُہ جو
کِسی کو کَبھی سُنائی نَہ تھی
Result:
