CamelCase

New words created by smashing together capitalized words.

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

Some people dislike linking by CamelCase. While Trac remains faithful to the original Wiki style, it provides a number of ways for making life easier to these people.

• There's an option to simply ignore links to missing pages when the link is written using the CamelCase style, instead of that word being replaced by grey links followed by a question mark. That's quite useful when CamelCase style is used to name code artifacts like class names and there's no corresponding page for them.
• There's an option to automatically insert space characters between words constitutive of a CamelCase link, when rendering the link.
  e.g. Camel Case
• Creation of explicit Wiki links is also easy, see WikiPageNames for details.
• Lastly, wiki formatting can be disabled completely in some places (e.g. when rendering commit log messages)

See relevant configuration settings:

[wiki]

default_edit_area_height	Default height of the textarea on the wiki edit page. (Since 1.1.5)	20
ignore_missing_pages	Enable/disable highlighting CamelCase links to missing pages.	disabled
max_size	Maximum allowed wiki page size in characters.	262144
render_unsafe_content	Enable/disable the use of unsafe HTML tags such as <script> or <embed> with the HTML WikiProcessor. For public sites where anonymous users can edit the wiki it is recommended to leave this option disabled.	disabled
safe_origins	List of URIs considered "safe cross-origin", that will be rendered as img element without crossorigin="anonymous" attribute or used in url() of inline style attribute even if [wiki] render_unsafe_content is false (since 1.0.15). To make any origins safe, specify "*" in the list.	data:
safe_schemes	List of URI schemes considered "safe", that will be rendered as external links even if [wiki] render_unsafe_content is false.	cvs,file,ftp,git,irc,http,https,news,sftp,smb,ssh,svn,svn+ssh
split_page_names	Enable/disable splitting the WikiPageNames with space characters.	disabled

[wikiextras]

done_phrases	Analogous to FIXME-phrases, but presentation is less eye-catching.	DONE,DEBUGGED,FIXED,REVIEWED
fixme_phrases	A list of attentional phrases or single words, separated by comma (,) that will be highlighted to catch attention. Any delimiter ():<> adjacent to a phrase will not be presented. (i.e. do not include any of these delimiters in this list). This makes it possible to naturally write, for example, FIXME: in a wiki text, but view the phrase highlighted without the colon (:) which would not look natural. Use the ShowPhrases macro to show a list of currently defined phrases.	BUG,FIXME
lbox_width	Width of left aligned boxes (defaults to rbox_width).	300
rbox_width	Width of right aligned boxes.	300
shadowless_boxes	Use shadowless boxes.	disabled
todo_phrases	Analogous to FIXME-phrases, but presentation is less eye-catching.	REVIEW,TODO
wide_toc	Right aligned boxes with table of contents, produced by the PageOutline macro, are either as wide as ordinary right aligned boxes (true) or narrow (false).	disabled

[wikiextras-custom-phrases]

Custom phrases are configurable by providing associations between a CSS class and the list of phrases separated by comma.

Example:

[wikiextras-custom-phrases]
nice = NICE, COOL

[wikiextras-symbols]

The set of symbols is configurable by providing associations between symbols and wiki keywords. A default set of symbols and keywords is defined, which can be revoked one-by-one (_remove) or all at once (_remove_defaults).

Example:

[wikiextras-symbols]
_remove_defaults = true
_remove = <- ->
&laquo; = <<
&raquo; = >>
&sum; = (SUM)
&hearts; = <3

Keywords are space-separated!

A symbol can also be removed by associating it with no keyword:

← =

Use the ShowSymbols macro to find out the current set of symbols and keywords.

_remove	Space-separated(!) list of keywords that shall not be interpreted as symbols (even if defined in this section).	(no default)
_remove_defaults	Set to true to remove all default symbols.	disabled
