WebLua 5.2+ __pairs and __ipairs. Lua 5.2 introduced the __pairs and __ipairs methods for controlling the behavior of pairs and ipairs for a table in for loops. The __pairs and __ipairs method work like standard iterator methods. Below is an example of a stateless iterator that behaves like the default pairs and ipairs iterators, but can be overridden to get loop … WebWe need to use ipairs because we want to list all the portals in the order -- they were passed to the template, but we also want to be able to deal with positional arguments passed explicitly, for example -- { {portal-inline Politics}}. The behaviour of ipairs is undefined if nil values are present, so we need to make sure they are all removed ...
