維基詞典,自由的多語言詞典


--[[
This module looks up the Greek entry title in "Module:R:Woodhouse/psia1_to_infs",
a list of verbs, and adds any infinitive forms to a list including the page 
title itself, in both potential proper and common forms.  This list of Greek 
forms is used to retrieve English headwords in Woodhouse's dictionary from 
"Module:R:Woodhouse/reverse_index".  The infinitives step is necessary because 
Woodhouse mostly thus identifies verbs.  The function get_page() then looks up
each English headword alphabetically in "Module:R:Woodhouse/page_headwords", or
"Module:R:Woodhouse/page_headwords_proper", or both, per 
"Module:R:Woodhouse/proper_or_both", to find  page numbers in the paper edition 
of the dictionary.  This `abstract' page number is slightly altered with a few 
exceptions to obtain the page number used in the ARTFL project's URL.  These 
URLs are returned with bibliographical information and HTML for display. A 
remaining issue is that, about 5% of the time, the page number will be off by
one or two.  This problem may be slightly intricate to solve completely.

8 May 2020: Changed reverse_index implementation to reverse_index_tab_delimited implementation to save memory (The Lua table consumed 8x the binary text size.)

--comment for calculate_page_number_divergence:
--page_number_divergence results from a few buffer pages before the first
--headword, and subsequently, a few multi-page entries leaving some pages
--without headwords.  Each time this latter takes place, the index of 
--page-initial headwords drifts from the physical page number.
