This is a (supposedly, with maintenance) complete list of templates on Rosetta Code.

As of this writing, most haven't been actively used in months. If you're looking for something to do, figure out if any of them are no longer needed. Otherwise some of them use poor formatting, and could use improvement. Finally, they should all be categorized according to the categories below. Be sure to include the category reference in <noinclude></noinclude> tags, so the pages the templates are used in don't get categorized in such a manner.

==Permanent templates==

Categorical

Most templates that should be placed permanently on a page denote categories like compilers, IDEs, programming languages, tasks, etc. Use [[Template:Task]], [[Template:Puzzle]], or [[Template:Language]] as an example of what a permanent template should look like.

Dynamic

Some templates, like [[Template:Header]] or [[Template:BoxImage]], use special behaviors. Be careful about editing them; Here there be dragons. Some, like Header, depend on specific page placement. If you change the output of the template, you risk breaking something in how the page works. Practice in the [[Help:Sandbox|Sandbox]]. In the case of Header specifically, you risk breaking the vast majority of pages on Rosetta Code. (But I trust you won't do that.)

==Temporary templates==

Some templates are only supposed to be on a page briefly, like [[Template:Stub]] or [[Template:Broken]]. In order to speed their removal, they need to stand out. See the formatting for Stub or Broken for an idea of how to do this appropriately.
