--[[--------------------------< G E T _ C O U N T >------------------------------------------------------------

returns a counter value according to the keyword extracted from the table; maintains count and hcount. Inserts
a space character ahead of <count> or <hcount> so that, in the case of negative indexes, the negation operator
is not mistaken for part of the wikitable markup. Returns:
| -<count> – a cell value
instead of:
|-<count> – row markup with extraneous text

The keywords have the meanings:
_row_count: use row counter value (count); the hold counter (hcount) is same as count
_row_count_hold: use the value currently assigned to hcount; bump count but do not bump hcount

]]

local function get_count (keyword)
count = count + 1; -- always bump the count
if '_row_count' == keyword then -- bump hcount, return new count value
hcount = count;
return ' ' .. count; -- insert a leading space ahead of count
elseif '_row_count_hold' == keyword then -- current hcount value without increment
return ' ' .. hcount; -- insert a leading space ahead of hcount
end
end

--[[--------------------------< R O W _ N U M B E R S >--------------------------------------------------------

-- We subtract one because the get_count function increments this before use.

-- BUG. The <nowiki> trick does not work in VisualEditor, mobile app, or Special:ExpandTemplates.
-- get the table from the nowiki tags passed as arguments
tbl_str = mw.text.unstripNoWiki (args[1]);

-- undo <nowiki>'s escaping of the wikitext (mw.text.decode (tbl_str); is too aggressive)
tbl_str = tbl_str:gsub('<', '<'):gsub('>', '>');
else
-- No MediaWiki bugs here (hopefully), but you need to escape = signs with {{=}} like normal.
-- It is not possible to circumvent this because named parameters are not passed to Lua in a
-- defined order, always have whitespace trimmed, etc.
