@Mr. Stradivarius: I have edited the module, but get an error in line 62 that won't let me save it. Here is what I have in mind:
-- This module implements {{Ancient Olympiads}}. It converts a year in the Gregorian
-- calendar to the equivalent year of the ancient Greek era organized by Olympiads.
local data = mw.loadData( 'Module:Ancient Olympiads/data' )
local lang = mw.language.getContentLanguage()
local p = {}
function p._main( inputYear )
-- Convert the input to an integer if possible. Return "N/A" if the input could
-- not be converted, or if the converted input is too big or too small.
inputYear = tonumber( inputYear )
if not inputYear or inputYear > tonumber( lang:formatDate( 'Y' ) ) then
return "''N/A''"
end
-- Find the length of the data.
-- We need the length of the data so that we can loop through it backwards.
-- Normally we can get the length of tables with the # operator, but this
-- doesn't work with mw.loadData, as mw.loadData uses a metatable, and the
-- # operator doesn't work for tables that use metatables.
-- What do you mean with length of table? How many entries? numberOl, year, winner = 3, adding note would be 4 ?
local dataLength = 0
for i, t in ipairs( data ) do
dataLength = i
end
-- Find the year in the data page and display the output.
for i = dataLength, 1, -1 do
local t = data[i]
if inputYear >= t.year then
-- Get data values from the data page.
local numberOl = t.numberOl
local winner = t.winner
local inbetweenYear = inputYear - dataYear
local note = t.note
if inputYear == t.year then
-- year of the Olympiad, test with = p._main( -496 )
-- The specification 'Winner of the Stadtion race' could also be done with a <ref>note</note>, but I like my current solution.
return string.format(
'%s, [[Olympiad]] ([[, %s,|victor]][[Winner of the Stadion race|)¹]]',
t.numberOl, t.winner
)
end
elseif inputYear > t.year then
-- Years 2-4 of the Olympiad, test with = p._main( -495 ) etc.
-- in the following string the comma after [[Olympiad]] should be actually a comma and not a command.
return string.format(
'%s, [[Olympiad]], year %d',
t.numberOl, inbetweenYear + 1
)
end
if inputYear < t.year then
-- Our input year was less than the year of the first Olympiad.
return string.format(
'%d before the [[776 BC|1st]] [[Olympiad]].',
inputYear
)
end
end
end
end
-- the previous line seems to have an error.
function p.main( frame )
-- If you only want to run this module from another Lua module, you can get
-- rid of this function entirely. This function is only used if you want to
-- run this individual module from a template.
local args = require( 'Module:Arguments' ).getArgs( frame, {
parentOnly = true
} )
return p._main( args[ 1 ] )
end
return p
