+This plugin allows ikiwiki to syntax highlight source code, using
a fast syntax highlighter that supports over a hundred programming
languages and file formats.
## prerequisites
You will need to install the perl bindings to the
-[highlight library](http://www.andre-simon.de/), which in Debian
-are in the [[!debpkg libhighlight-perl]] package.
-
-## configuration
-
-Nothing will be highlighted by default.
-To enable syntax highlighting, use the `tohighlight` setting in your
-setup file to control which files should be syntax highlighted.
-Here is a typical setting for it, enabling highlighting for files
-with the extensions .c, etc, and also for any files named "Makefile".
-
- tohighlight => .c, .h, .cpp, .pl, .py, Makefile:make",
-
-It knows what language to use for most filename extensions (see
-`/etc/highlight/filetypes.conf` for a partial list), but if you want to
-bind an unusual filename extension, or any file without an extension
-(such as a Makefile), to a language, you can do so by appending a colon
-and the name of the language, as illustrated for Makefiles above.

+your distribution does not have them, look in `examples/swig`
+in highlight's source.
## embedding highlighted code
To embed highlighted code on a page, you can use the
-[[ikiwiki/directive/format]] directive.
+[[format]] plugin.
For example:
}
"""]]
-You can do this for any of the extensions/filenames enabled in
-`tohighlight`.
+ \[[!format diff """
+ -bar
+ +foo
+ """]]
-## colors
+You can do this for any extension or language name supported by
+the [highlight library](http://www.andre-simon.de/) -- basically anything
+you can think of should work.
-The colors etc used for the syntax highlighting are entirely configurable
-by CSS. See ikiwiki's [[style.css]] for the defaults.
+## highlighting entire source files
+
+To enable syntax highlighting of entire standalone source files, use the
+`tohighlight` setting in your setup file to control which files should be
+syntax highlighted. Here is a typical setting for it, enabling highlighting
+for files with the extensions .c, etc, and also for any files named
+"Makefile".

+and the name of the language, as illustrated for Makefiles above.
-With this plugin enabled, source files become full-fledged ikiwiki pages,
-which means they can include [[WikiLinks|ikiwiki/wikilink]] and
-[[directives|ikiwiki/directive]] like any other page can, and are also
-affected by the [[smiley]] plugin, if it is enabled. This can be
-annoying if your code accidentially contains things that look like those.

On the other hand, this also allows your syntax highlighed
source code to contain markdown formatted comments and hyperlinks
/* \[[!format mdwn """
This comment will be formatted as *markdown*!
- See [[bar.h]].

-## security
+Finally, bear in mind that this lets anyone who can edit a page in your
+wiki also edit source code files that are in your wiki. Use appropriate
+caution.
