I'm testing a template [:it:s:Template:Pg]] (calling a Lua module) that
fastly converts book page numbers, passed as the unique parameter to the
template, into links to right djvu pages, without any need to add delta
parameters and linking any format for page number (arabic, roman, other...)
since page numbers are seen as strings.
The Lua script reads a data page, containing tables for conversion book
page->djvu page and reverse, using mw.loadData() function for max
efficiency (often there are dozens, sometimes hundreds of links to pages
into a single book page; ity happens into analytical indexes, glossaries
and so on).
The Lua data page is written in a eyeblink by a js script, which reads and
parses html of Index: page, produced by pagelist tag; so it's very
comfortable to fill such data page and to update it, if pagelist parameters
are updated.
Is this "beginner's Lua exercise" someway interesting/inspiring in your
opinion?
