-- Generate a string to substitute into a particular form in a Wiki-markup table. `forms` is the list of forms, -- generated by concat_word_forms. `is_lemma` is true if we're formatting the entry for use in displaying the lemma -- in the declension table title. In this case, we don't include the translit, and remove monosyllabic accents from the -- Cyrillic (but not in multiword expressions). `accel_form` is the form code to speicfy in the accelerator, e.g. -- 'nom|m|s', or nil for no accelerator. `lemma_forms` is the list of {RU, TR} lemma forms for use in the accelerator, -- or nil if `accel_form` is nil. `remove_monosyllabic_accents_lemma_only` indicates that monosyllabic accents should -- be removed only in the lemma; otherwise we remove them from all forms. (FIXME: Rethink why we have this flag; we -- should be consistent.) function export.show_form(forms, is_lemma, accel_form, lemma_forms, remove_monosyllabic_accents_lemma_only) local russianvals = {} local latinvals = {} local lemmavals = {}

-- First fetch the lemma forms and translit. If there are adjacent forms that have identical Russian including -- stress but different translit (e.g. азербайджа́нец with translits 'azerbajdžánec' and 'azɛrbajdžánec'), we -- combine the translits, comma-separating them. (This is necessary because there is currently only one tr=	-- field per term.) We don't do this when processing the forms below; instead we handle this in a different -- and more general fashion (see below). local lemmaru, lemmatr if accel_form and lemma_forms and lemma_forms[1] ~= "-" then lemma_forms = com.combine_translit_of_duplicate_forms(com.strip_notes_from_forms(lemma_forms)) for i, form in ipairs(lemma_forms) do			local ru, tr = unpack(lemma_forms[i]) ru, tr = com.remove_monosyllabic_accents(ru, tr) lemma_forms[i] = {ru, tr} end lemmaru, lemmatr = com.unzip_forms(lemma_forms) end

-- Accumulate separately the Russian and transliteration into RUSSIANVALS and LATINVALS, then concatenate each down -- below. We need a fair amount of logic here: -- (1) to separate out footnote symbols; -- (2) to separate out the hypothetical marker (a footnote symbol but causes display of the Russian and translit	--    in a special font); -- (3) to maybe remove monosyllabic accents; -- (4) to deduplicate repeated forms. -- We used to generate the display (HTML) as we went, but this prevented proper deduplication because the -- accelerator classes included in the HTML were different for otherwise identical forms. (Specifically, if two	-- forms are the same in the Russian but different in the translit, the Russian will have different display forms	-- because the translit is included in the accelerator classes.) So what we do is accumulate, separately for the -- Russian and translit, objects containing the entry (Russian or translit), the separated footnote symbols, -- whether the entry is hypothetical, and (for Russian only) the corresponding translit(s), for accelerator -- generation. As we accumulate, we duduplicate based only on comparing the entries of two objects. If we need to	-- deduplicate two objects, we also need to combine their footnotes and transliteration (in the latter case, by	-- comma-separating; we do this because there is only one tr= field for each term). for _, form in ipairs(forms) do		local ru, tr = form[1], form[2] local ruentry, runotes = m_table_tools.separate_notes(ru) local trentry, trnotes if tr then trentry, trnotes = m_table_tools.separate_notes(tr) trnotes = rsub(trnotes, HYPMARKER, "") end if (is_lemma or not remove_monosyllabic_accents_lemma_only) then ruentry, trentry = com.remove_monosyllabic_accents(ruentry, trentry) end local ishyp = rfind(runotes, HYPMARKER) if ishyp then runotes = rsub(runotes, HYPMARKER, "") end local ruobj = {entry = ruentry, tr = {trentry or true}, ishyp = ishyp, notes = runotes} if not trentry then trentry = com.translit_no_links(ruentry) end if not trnotes then trnotes = com.translit_no_links(runotes) end local trobj = {entry = trentry, ishyp = ishyp, notes = trnotes}
