Editing Module:Convert/doc (section)

== Templates and modules ==
Templates that invoke this module are:
* [[Template:Convert]]
* [[Template:Cvt]] {{green|1=(convert with abbr=on)}}

The following modules are required:
* [[Module:Convert]] – ''(this module)'' code to convert units
* [[Module:Convert/data]] – unit definitions
* [[Module:Convert/text]] – text messages, and parameter names and values

The following modules are optional and are used only if required and if the module exists:
* [[Module:Convert/extra]] – extra (temporary) unit definitions; used if a unit is not found in [[Module:Convert/data]]
* [[Module:ConvertNumeric]] – code to spell an input value in words (only English is supported; however, see [[:vi:Module:ConvertNumeric]])

For Wikidata support the following modules are required:
* [[Module:Convert/wikidata]]
* [[Module:Convert/wikidata/data]]

The following help pages are available:
* [[Help:Convert]] – overview
* [[Help:Convert messages]] – describes error and warning messages; messages link to this page so it is required when the module is copied to another wiki
* [[Help:Convert units]] – overview of units

A page containing a convert error is added to the following hidden category, providing the page is in a specified [[WP:Namespace|namespace]] (articles, by default):
* {{clc|Convert errors}}

Units are defined in the wikitext of the master list of units.
* [[Module:Convert/documentation/conversion data]] – master list of unit definitions
* [[Module:Convert/makeunits]] – translates wikitext from the master list to Lua
* [[Module talk:Convert/makeunits]] – makeunits results; copy the text to [[Module:Convert/data]]

[[Module:Convert/data]] is transcluded into every page using the convert module, so experimenting with a new unit in that module would involve a significant overhead. The [[Module:Convert/extra]] module is an alternative which is only transcluded on pages with a unit that is not defined in the main data module.

[[Module talk:Convert/show]] lists all unit links so they can be checked.
