Module:Example

This module provides a function to perform text replacements on a specified page
using a template replacement table defined in a separate page.

Usage: {{#invoke:Example|main|BasicPage=OriginalPage|ReplaceList=ReplacementsTable}}

Parameters:
- BasicPage: The name of the page on which the text replacements should be performed.
- ReplaceList: The name of the page containing the replacement table.

Replacement Table Format:
The replacement table should be defined in the following format:
`Key1`||Replacement1;
`Key2`||Replacement2;
...

- Each line represents a single replacement entry.
- The key and replacement value are separated by "||".
- The key should be enclosed in backticks (`).
- The replacement value can contain wikitext formatting.
- Each line should end with a semicolon (;).
- Empty lines are ignored.

Example Replacement Table:
`A`||'''Apple''';
`B`||''Banana'';
`C`||Carrot;
]]

local p = {}

function p.main(frame)
local args = frame.args
local BasicPage = frame.args['BasicPage']
local ReplaceList = frame.args['ReplaceList']

if not BasicPage then
return "Error: BasicPage parameter is missing."
end

if not ReplaceList then
return "Error: ReplaceList parameter is missing."
end

local replaceTable = {}
local replaceContent = frame:expandTemplate{title = ReplaceList}
for line in replaceContent:gmatch("[^\n]+") do
local key, value = line:match("(`[^`]+`)||([^;]+)")
if key and value then
key = mw.text.trim(key)
value = mw.text.trim(value)
replaceTable[key] = value
end
end

local page = mw.title.new(BasicPage)
if page then
local pageContent = page:getContent()
if pageContent then
-- Perform text replacements based on replaceTable
for key, value in pairs(replaceTable) do
pageContent = pageContent:gsub(key, value)
end
return pageContent
else
return "Page " .. BasicPage .. " exists but has no content."
end
else
return "Page " .. BasicPage .. " does not exist."
end
