Insert Diff Tag

Inserts a diff between two pages. The "Diff.jsp" places two variables into the JSP PageContext:

insertdiff.old - The version number of the old version.
insertdiff.new - The version number of the new version.

These have been parsed from the HTTP parameters by "Diff.jsp". The resulting HTML uses a few CSS styles:

TABLE.diff - The whole table gets this style.
TD.diff - Each unchanged line gets this.
TD.diffadd - Each added line gets this style.
TD.diffrem - Each removed line gets this style.

Usage

<wiki:InsertDiff page="<page name>" />

Parameters

page: Page name.

Example

<code>
<wiki:InsertDiff />
</code>

Might result into something like this:

<code>
   <table class="diff" border=0 cellspacing=0 cellpadding=0>
       <tr><td class="diff">Line 16 was replaced by line 16</td></tr>
       <tr><td bgcolor=#FF9933 class="diffrem">- [Sandbox/cens7.gif]</td></tr>
       <tr><td bgcolor=#99FF99 class="diffadd">+ Foobar.</td></tr>
   </table>
