Underscore_Wiki_Page automatic linking


This is a one-file plugin that transforms the MediaWiki styled Underscore_Wiki_Page to a link automatically, as it does with CamelCaseWikiPage see CamelCase. This plugin requires that the wiki page name must have at least two words and each word must start with an upper case letter, like Foo_Bar_Baz.

It was originally created to make class names, like Controller_Frontend_Foobar link to the corresponding wiki page automatically. However, we do think that CamelCaseStyle is prettier and should still be used for Trac wiki pages.

Download the zipped source from here.

Alternatively, you can download it using wget:

$ wget -O /path/to/trac/env/plugins/


You can check out UnderscoreWikiPlugin from here using Subversion, or browse the source with Trac.


This plugin consists of a single file. You can simply put the file directly in your plugins directory.

Make sure it is readable by the user running Trac.


This plugin has two configuration options that can be set under a [underscore-wiki] section in TracIni.

  • ignore_missing_pages - Enable/disable highlighting Underscore_Wiki_Page links to missing pages. Defaults to false, which means not ignoring them, but they will be shown in grey with a question mark.
  • uppercase_in_words - Enable/disable using upper case letters in places other than the first character of every word. Only Foo_Bar is supported by default, setting this to true adds support for Foo_BAR, Foo_BaR, FOO_Bar, etc. Defaults to false.

This should look like:

ignore_missing_pages = true
uppercase_in_words = false
