Module:MLB standings

Module documentation[view] [edit] [history] [purge]

Description

This module is used to implement Template:MLB standings, a helper template used in the implementation of templates for Major League Baseball division standings, such as Template:2013 AL East standings.

Module:MLB standings/data contains configuration data for this module:

• the number of wild cards per league, for a specified range of seasons
• abbreviations to use for the MLB divisions, when mapping the division to the name of the corresponding standings template

The test cases at Template:MLB standings/testcases are used to test this module.

The above documentation is transcluded from Module:MLB standings/doc. (edit | history)
Editors can experiment in this module's sandbox (edit | diff) and testcases (create) pages.
