Editing Module:Adjacent stations/doc (section)

== Basic structure ==
Two modules are demonstrated below:
{| class="wikitable"
|-
| [[Module:Adjacent stations/blank|Blank]] || {{syntaxhighlight|lang=lua|{{Module:Adjacent stations/blank}}}}
|-
| [[Module:Adjacent stations/Kaohsiung Rapid Transit|Example]] || {{syntaxhighlight|lang=lua|{{Module:Adjacent stations/Kaohsiung Rapid Transit}}}}
|}
The example module is [[Module:Adjacent stations/Kaohsiung Rapid Transit]].
* The two required table entries are "station format" and "lines". The former is a table with data to form links to station articles, and the latter is a table containing a table for each line.
* "system title" is the text in the middle cell of the table header row.
* "station format" defines the default name format for station articles and exceptions. The first variable ("%1 metro station") is the default. Exceptions are listed as key–value pairs (e.g. "Zuoying"–"Zuoying HSR station"), where the key is the input name. The module displays the input name and links to the article with the formatted name, replacing "%1" with the input. Alternatively, the full wikilink and be entered. This can be used to have the display be different from the input.
* "lines" is where the lines are listed. The names here are used internally and not displayed, so choose a concise one.
* "line title" is the text displayed in the middle of each row indicating the line; "left terminus" is the default station name for the left side terminus, and "right terminus" is the default station name for the right side terminus.
* Each "color" entry is the colour of the line.

Below is [[Module:Adjacent stations/Taiwan High Speed Rail]]:

* <var>x</var> (defined in the first line) is a string used for formatting the station name. The variable <var>x</var> is used inside the "station format" table for the three articles where the title ends in "station" instead of "HSR station". This practice is optional but helpful when many articles fit a second pattern.
* The module recognises a virtual line named <code>["_default"]</code>. The title and colour of this line is used for all lines unless overridden. Parameters are used in the absence of a specified <code>line=</code> in transclusion.
