1 An overview of some of ikiwiki's features:
6 Rather than implement its own system for storing page histories etc,
7 ikiwiki uses a real Revision Control System. This isn't because we're
8 lazy, it's because a real RCS is a good thing to have, and there are
9 advantages to using one that are not possible with a standard wiki.
11 Instead of editing pages in a stupid web form, you can use vim and commit
12 changes via [[Subversion]]. Or work disconnected using svk and push your
13 changes out when you come online. Or use [[git]], [[tla]], or [[mercurial]]
14 to work in a distributed fashion all the time. (It's also possible to
15 [[plugins/write]] a plugin to support other systems.)
17 ikiwiki can be run from a [[post-commit]] hook to update your wiki
18 immediately whenever you commit a change using the RCS.
20 Note that ikiwiki does not require a RCS to function. If you want to
21 run a simple wiki without page history, it can do that too.
25 ikiwiki is a wiki compiler; it builds a static website for your wiki, and
26 updates it as pages are edited. It is fast and smart about updating a wiki,
27 it only builds pages that have changed (and tracks things like creation of
28 new pages and links that can indirectly cause a page to need a rebuild)
30 ## Supports many markup languages
32 By default, pages in the wiki are written using the [[MarkDown]] format.
33 Any page with a filename ending in ".mdwn" is converted from markdown to html
34 by ikiwiki. Markdown understands text formatted as it would be in an email,
35 and is quite smart about converting it to html. The only additional markup
36 provided by ikiwiki on top of regular markdown is the [[WikiLink]] and
37 [[PreprocessorDirective]].
39 If you prefer to use some other markup language, ikiwiki allows others to
40 easily be added by [[plugins]]. For example it also supports traditional
41 [[plugins/WikiText]] formatted pages, pages written as pure
42 [[plugins/HTML]], or pages written in [[reStructuredText|plugins/rst]].
44 ikiwiki also supports files of any other type, including plain text,
45 images, etc. These are not converted to wiki pages, they are just copied
46 unchanged by ikiwiki as it builds your wiki. So you can check in an image,
47 program, or other special file and link to it from your wiki pages.
51 You can turn any page in the wiki into a [[blog]]. Pages matching a
52 specified [[PageSpec]] will be displayed as a weblog within the blog
53 page. And RSS or Atom feeds can be generated to follow the blog.
55 Ikiwiki's own [[TODO]], [[news]], and [[plugins]] pages are good examples
56 of some of the flexible ways that this can be used. There is also an
57 [[example_blog|examples/blog]] set up that you can copy into your own wiki.
59 Ikiwiki can also [[plugins/aggregate]] external blogs, feeding them into
60 the wiki. This can be used to create a Planet type site that aggregates
63 ## Valid html and [[css]]
65 ikiwiki aims to produce
66 [valid XHTML 1.0](http://validator.w3.org/check?url=referer).
67 ikiwiki generates html using [[templates]], and uses [[css]], so you can
68 change the look and layout of all pages in any way you would like.
72 Plugins can be used to add additional features to ikiwiki. The interface
73 is quite flexible, allowing plugins to implement additional markup
74 languages, register [[PreProcessorDirective]]s, hook into [[CGI]] mode,
75 and more. Most of ikiwiki's features are actually provided by plugins.
76 Ikiwiki's backend RCS support is also pluggable, so support for new
77 revision control systems can be added to ikiwiki.
81 After rather a lot of fiddling, we think that ikiwiki correctly and fully
82 supports utf8 everywhere.
86 The above are the core design goals and features of ikiwiki, but on that
87 foundation a lot of other important features are added. Here is an
88 incomplete list of some of them.
92 You can tag pages and use these tags in various ways. Tags will show
93 up in the ways you'd expect, like at the bottom of pages, in blogs, and
94 in RSS and Atom feeds.
96 ### [[SubPages|SubPage]]
98 Arbitrarily deep hierarchies of pages with fairly simple and useful
99 [[SubPage/LinkingRules]]
103 Automatically included on pages. Rather faster than eg MoinMoin and
104 always there to help with navigation.
106 ### Smart merging and conflict resolution in your web browser
108 Since it uses a real RCS, ikiwiki takes advantage of its smart merging to
109 avoid any conflicts when two people edit different parts of the same page
110 at the same time. No annoying warnings about other editors, or locking,
111 etc, instead the other person's changes will be automatically merged with
112 yours when you commit.
114 In the rare cases where automatic merging fails due to the same part of a
115 page being concurrently edited, regular commit conflict markers are
116 shown in the file to resolve the conflict, so if you're already familiar
117 with that there's no new commit marker syntax to learn.
119 ### [[RecentChanges]], editing pages in a web browser
121 Nearly the definition of a wiki, although perhaps ikiwiki challenges how
122 much of that web gunk a wiki really needs. These features are optional
123 and can be enabled by enabling [[CGI]].
125 ### User registration
127 Can optionally be configured to allow only registered users to post
128 pages; online user registration form, etc.
132 Thanks to subpages, every page can easily and automatically have a
133 /Discussion subpage. By default, these links are included in the
134 [[templates]] for each page.
138 Wiki admins can lock pages so that only other admins can edit them.
142 Well, sorta. Rather than implementing YA history browser, it can link to
143 [[ViewCVS]] or the like to browse the history of a wiki page.
147 ikiwiki can use the [[HyperEstraier]] search engine to add powerful
148 full text search capabilities to your wiki.
152 ikiwiki can be configured to send you commit mails with diffs of changes
157 Can be set up so that w3m can be used to browse a wiki and edit pages
158 without using a web server.
