[edit] ignore all nowiki tags

[edit] replace http links

   $text = preg_replace('/\\[(http[\\w:?=@&\\/#._;\\-%]*) ([^\\]]*)\\]/e', "create_html_link('$1', '$2')", $text);

[edit] replace #if statements

   $text = preg_replace('/{{#if\\: {{{(\\w*)}}}\\|([^|}]*)(\\|[^}]*)?}}/e', "calc_if(\"$1\", \"$2\", \"$3\")", $text);

[edit] substitute variables - somewhat time expensive

   $text = preg_replace("/{{{(\\w*)}}}/e", "wfMsg('$1')", $text);

[edit] break page into headers

[edit] if there is no text before the header, erase that part, else add a noheader section

[edit] what needs to be done

• I am currently working on calc_if, which may be used to handle conditionals in the toolbox. It may simply return an array of the arguments so that the sidebar can be cached.
• possible li styles, but html works for some things.
• something to make this language neutral and cached.
• stop using function for link if it remains simple
