Module:Citation/CS1/Configuration

This configuration file contains various data that controls the functioning of Module:Citation/CS1 and hence the way that Lua-based citations are generated.

It has several sections among which are:

  1. translation tables that contain most of the literal strings that may be included in Lua-based citation. If editors are copying this Module to another wiki using a language other than English, then they should translate each of these values into that language.
  2. a list of error conditions specifying what text to display, what category to include (if any), and what help page section to refer to when errors are detected
  3. a list of ID handlers specifying the recognized document IDs, such as ISBN, DOI, etc., and how to format them.


These files comprise the module support for cs1|2 citation templates:
