Editing Module:Dump/doc (section)

== Dump of a table for another module ==

If there is a problem debugging a module, it can be helpful to use a sandbox copy of the module to display the contents of a table to confirm that it contains expected data. The following shows how a module can dump a table.
<syntaxhighlight lang="Lua">
local p = {}
function p.main(frame)
	local example = {
		link = true,
		fruit = { yellow = 'bannana', red = 'cherry' },
		11, 22, 33,
	}
	local dump = require('Module:Dump')._dump
	return dump(example, 'example')
end
return p
</syntaxhighlight>

With the above code in Module:Example, the result could be displayed by previewing:
:<code><nowiki>{{#invoke:example|main}}</nowiki></code>

The module contains a complex table for testing. The table can be displayed by previewing:
:<code><nowiki>{{#invoke:dump|testcase}}</nowiki></code>
