New wiki links are automatically created when concatenating capitalized words, such that for example the word 'Camel' and the word 'Case' concatenated form a link to this Camel Case page.
CamelCase is the original wiki convention for creating hyperlinks, with the additional requirement that the capitals are followed by a lower-case letter; hence “AlabamA” and “ABc” will not be links.
Customizing the Wiki behavior
While Trac remains faithful to the original Wiki style, it provides a number of ways to accommodate users with different preferences:
- To prevent the creation of a new link of a camel-cased word, prefix with '!': !CamelCase.
- To ignore links to missing pages when the link is written using the Camel Case style, that word can instead be replaced by a gray link followed by a question mark. This is useful in cases when Camel Case style is used to name code artifacts like class names and there's no corresponding page for them. This option can be set in ignore_missing_pages in the [wiki] section of Trac Ini.
- There's an option (split_page_names in the [wiki] section of Trac Ini) to automatically insert space characters between the words of a Camel Case link when rendering the link.
- Creation of explicit Wiki links is also easy, see Wiki Page Names for details.
- Wiki formatting can be disabled completely in some places, for example when rendering commit log messages. See wiki_format_messages in the [changeset] section of Trac Ini.
See Trac Ini for more information on the available options.
