Talk:Tree traversal

Wiki markup problem :Category v. Category references

Note: This documents a markup glitch or documentation error or non-intuitive feature in the markup. Not sure if this is where this should live.

Problems observed in the following:

...
== Icon and Unicon ==
==={{header|Icon}}===
<lang Icon>procedure main()
...
end</lang>

...
Note: A [[Category:Unicon]] specific example has not been provided.    <=== SIDE EFFECT THIS CAUSES the task to show up in tasks completed Unicon

I diagnosed the side effect - Tree Traversal shows up as a completed task under Unicon.

• There is no {{header|Unicon}} tag anywhere on the page.
• The [[Category:Unicon link]]produces nothing visible unlike other [[..]] tags. This also causes the problem.
• Replacing the reference above with [http://rosettacode.org/wiki/Category:Unicon Unicon] doesn't cause the problem.

When you want to make a visible link to a category you need to put a : in front like this: [[:Category:Icon]] or [[:Category:Icon|custom text]]. These will show this: Category:Icon or custom text. Is that what you were trying to do? --Mwn3d 02:51, 13 April 2010 (UTC)

Yes I was but that what's odd is that Template:Example-needs-review and Category_talk:Icon w/o the :

Also, thanks with the : the Side effect above seems to be gone --Dgamey 03:48, 13 April 2010 (UTC)
