10 years ago Thanks for the information.
To summarize, there are two issues I identify:
- Missing feature: According to Kedārabhaṭṭa in vRttaratnAkara, a short vowel followed by a consonant cluster (i.e., multiple consonants), although guru by default, can optionally be treated as laghu if that consonant cluster happens to be the beginning of a new word. Implement this option. (With required UI changes, e.g. saying: "this verse can be read as <...> if an option is used in places x, y, z.")
- Treatment of pAdAnta laghus, which I've forked off as a separate issue #2.
So let's restrict this issue to discussing #1.
As I see it, to implement this, we'd like the metre-recognizing function to be passed in spaces as well, so that it can detect the beginning of words. The rest should be doable.

[Original subject: Defining Gurus and Laghus]
सानुस्वारो विसर्गान्तो दीर्घो युक्तपरश्च यः । वा पादान्तस्त्वसौ ग्वक्रो ज्ञेयोऽन्यो मातृको लृजुः ॥ ९
पदादाविह वर्णस्य संयोगः क्रमसंज्ञिकः । पुरःस्थितेन तेन स्याल्लघुताऽपि क्वचिद्गुरोः ॥ १०
These are the rules for Guru / Laghu in vRttaratnAkara. Rule 1: sAnusvAra - this is covered in the code by including M in the consonant list. Rule 2: visargAnta - this is also covered in the code by including H in the consonant list. Rule 3: dIrgha - This is also covered in the code by including the long_vowel variables. Rule 4: yuktapara - This needs a little refinement. This rule is made optional by the verse 10. Rule 5 - pAdAnta - pAdAnta laghu is treated as guru optionally. The commentary says पादस्तस्यान्ते वर्तमानो लघुरपि विभाषया गुरुः स्यात् । स च कविसमयव्यवहारात् द्वितीयचतुर्थयोरेव पादयोरन्ते वेदितव्यः । . Meaning thereby that this optionality will work only in case of the second or fourth pAda only. A laghu at the end of First or Third pAda will not have an option of being a guru optionally.
Rule 6: Others having short vowels are laghu.
Rule 7: This is important. This is an optional exception to the rule 4. When there is a conjoint at the start of a word (pada), (not pAda), the guru (as mandated by Rule 4) is sometimes treated as laghu. e.g. निद्रव्यो ह्रियमेति ह्रीपरिगतः प्रभ्रश्यते तेजसः Here, as the ति preceding ह्री is mandated to be guru by rule 4 - by rule 7, it remains laghu. If it is treated as guru - GGGLLGGGLLLG-GGLGGLG - doesnt correspond to zArdulavikrIDita meter. If it is treated as laghu - GGGLLGLGLLLG-GGLGGLG - corresponds to the meter.
This is optional. See: रागो नलिन्या हि निसर्गसिद्धस्तत्र भ्रमत्येव मुधा षडङ्घ्रिः ॥ Here, भ्र has त्र preceding, but still it got converted to dIrgha.
Also note that this applies only when the conjoint is at the start of a word (pada). see: प्रद्योतस्य प्रियदुहितरं वत्सराजोऽत्र जह्रे । Here, the ह्र in जह्रे is not at the beginning of a word. Therefore the guru is mandatory.
