There are three options for math markup that depends on the editor's math preference settings. These settings

are at [[Special:Preferences#mw-prefsection-rendering]] and are

PNG images

TeX source

MathML with SVG or PNG fallback

All three are heavy with html and css which don't belong in the metadata.

This function gets the rendered form of an equation according to the editor's preference. It then searches the

rendering for the text equivalent of the rendered equation and replaces the rendering with that.

local function coins_replace_math_stripmarker (value)

local stripmarker = '\127UNIQ%-%-math%-[%a%d]+%-QINU\127'; -- math stripmarker pattern

local rendering = value:match (value); -- is there a math stripmarker

if not rendering then -- when value doesn't have a math stripmarker, abandon this test

return value;

end

rendering = mw.text.unstripNoWiki (stripmarker); -- get the rendered value (or nil? ''? when math render error)

if rendering:match ('alt="[^"]+"') then -- if PNG math option

rendering = rendering:match ('alt="([^"]+)"'); -- extract just the math text

elseif rendering:match ('$%s+.+%s+%$') then -- if TeX math option; $ is legit character that is escapes as \$

rendering = rendering:match ('$%s+(.+)%s+%$') -- extract just the math text

elseif rendering:match ('<annotation[^>]+>.+</annotation>') then -- if MathML math option

rendering:match ('<annotation[^>]+>(.+)</annotation>') -- extract just the math text

else

return value; -- had math stripmarker but not one of the three defined forms

end

return value:gsub (stripmarker, rendering, 1);
