Bug ID: 67498
Summary: Frames aren't available outside of functions in
modules
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Scribunto

Create the following as Module:Foo:
local p = {}
local f = mw.getCurrentFrame()
function p.main(frame)
return 'The title of the current frame is ' .. f:getTitle()
end
return p
When {{#invoke:Foo|main}} is used in a page, a script error will be generated
because f is nil. Note the bug is not present in the console, where running
=p.main() will produce the expected result.
Also, if the following is created as Module:Bar:
local p = {}
local d = os.date()
function p.main(frame)
return 'The date when the module was ran was ' .. d
end
return p
{{#invoke:Bar|main}} will return a script error because the TTL logic in
os.date() assumes that frames are available at this point, when in fact they
are not. Again, this only malfunctions when called from wikitext; =p.main()
works properly from the console.
