This module lets you get around the |no html bug that Cargo has by avoiding |format=template.

To use, preface query arguments with q?. Even if you are only using one table, use |q?tables=. You may additionally specify |template=, |intro=, |outro=, |delimiter=, and |default=.

Use Lua names of all query parameters, so |q?join=, |q?groupBy, etc.

For simplicity of code, the named args parameter is required to be Yes, and you do not need to specify it.

Unlike |format=template, this wrapper will NOT rename parameters with underscores in them to use spaces instead.

Parameters & Invocation

|q?tables= 	corresponds to table / tables
|q?join= 	corresponds to join on

|q?groupBy= 	corresponds to group by
|q?having= 	corresponds to having
|q?orderBy= 	corresponds to order by
|q?limit= 	corresponds to limit
