* Link easily from blog posts to wiki pages in a way that does not need re-editing if I move the wiki and which copes with non-CamelCase [WikiWord]s.
! Approach
* Define custom tags that will be used in blog posts.
* Create [http://www.wordpress.org/ "WordPress"] filter plugin to replace custom tags (see [WordPress:Plugin/API]) with links to the relevant wiki pages.
!Usage
* Save the [.#code "code"] below into a suitably-named php file.
* Upload the file to the wp-content/plugins directory.
* Go to the !WordPress plugins admin screen and activate the plugin.
* Write a test post.
! Change history
* 2005-03-11 changed the regexes to be non-greedy - fixes bug where more than one wiki link on one line of blog post
! To Do
* A more sophisticated version would query the wiki to see if the pages existed already and alter the presentation appropriately.
* This plugin could become a general-purpose tag-replacer, the limit is your understanding of regular expressions!
