Template:METRORail

From Wikipedia, the free encyclopedia

This template employs intricate features of template syntax. Please do not alter it unless you are certain to understand its setup and parser functions and are ready to repair/revert all collateral damage if results are unexpected. Any experiments should be conducted and all improvements tested in either the template sandbox or your user space before applying anything here.

[edit] How to use

[edit] Normal station

Here is how you employ this template with a normal station (one with another station in either direction):

{{METRORail
|line=red
|this=Main Street Square Station
|prev=Bell Station
|next=Preston Station
}}

which creates the following:

[edit] Termini

If you do not define a next or previous station, the template will display "TERMINUS" like so:

{{METRORail
|line=red
|this=Fannin South Station
|next=Reliant Park Station
}}

which creates the following:

[edit] How this template handles user error

{{METRORail
|this=Fannin South Station
}}

It lets you know when you screw up, like so:

There appears to be an error in the way this template was coded.
    There is no line defined (|line=). Without one, the template cannot know which direction the next stations are. Please fix.
There appears to be an error in the way this template was coded.
     There is no previous station defined (|prev=) and no next station defined (|next=). If only a previous station or only a next station defined, the template renders the absent station as a terminus. However, it is highly irregular and highly improbable that there is only one station on a rail line. Please fix.
{| style="border: 1px solid #CCCCCC; width: 550px; padding:4px;" align="center" cellspacing="0" cellpadding="4px" |- | style="text-align: left; background-color: #f3f3f3;" | TERMINUS | style="text-align: center; background-color: #f3f3f3;" |METRORail | style="text-align: right; background-color: #f3f3f3;" |TERMINUS |- | style="width: 30%; text-align: left;" | None | style="width: 40%; text-align: center;" | Fannin South Station | style="width: 30%; text-align: right;" | None |}

[edit] Extensibility

The template knows that the METRORail Red Line goes in a north and south direction. If and when a new line is created, this template can be used for it. All that needs to be done is a simple addition to define the previous station direction (in this case south) and the next station direction (in this case north) and the color of text that should be used to display the name of the line (in this case, red).
