'''MoinMoin''' is a [[wiki software|wiki engine]] implemented in [[Python (programming language)|Python]], initially based on the PikiPiki wiki engine. Its name is a play on the North German greeting ''[[Moin]]'', repeated as in WikiWiki. The MoinMoin code is licensed under the [[GNU General Public License]] v2, or (at the user's option) any later version (except some 3rd party modules that are licensed under other Free Software licenses compatible with the GPL).<ref>{{cite web|url=https://moinmo.in/GPL |title=GPL |publisher=MoinMoin |date=2011-05-12 |access-date=2012-12-06}}</ref>
Dozens of organizations use MoinMoin to run public [[wikis]],<ref>{{cite web|url=http://trends.builtwith.com/cms/MoinMoin|title=MoinMoin Usage Statistics|publisher=builtwith.com|access-date=15 December 2014}}</ref> including free software projects [[Ubuntu (operating system)|Ubuntu]], [[Apache Software Foundation|Apache]], [[Debian]], and [[FreeBSD]].<ref>{{cite web|url=https://moinmo.in/|title=Other sites using the MoinMoin wiki engine|access-date=2008-10-01}}</ref>
MoinMoin faces a supportability gap in 2020, based on the January 2020 deprecation of Python 2.7.  The current release of Moinmoin, 1.9.11, is written in Python 2.7 and is not slated to be ported to Python 3.  Moinmoin 2.0, based on Python 3.5, is not yet released (as of November 2023), and "development is very slow going," according to their Python3 support page.<ref>{{cite web|url=https://moinmo.in/Python3 |title=Python3 |publisher=MoinMoin |date=2019-08-05 |access-date=2019-08-27}}</ref>  Installation of Moinmoin 1.9.11 now yields multiple warnings of this deprecation.
==Technical details==
MoinMoin's storage mechanism is based on [[Flat-file database|flat files]] and folders, rather than a [[database]]. This makes it easy to manipulate the content in a text editor on the server if necessary, including managing revisions if the wiki gets attacked by spammers.
MoinMoin supports [[Plug-in (computing)|plug-ins]] and can be extended via Macros and Actions. It also uses the idea of separate [[Parsing|parsers]], ''e.g.'', for parsing the wiki syntax, and formatters, ''e.g.'', for outputting [[HTML]] code, with a [[Simple API for XML|SAX]]-like interface between the two. Therefore, to output [[DocBook]] instead of HTML, one would only need to write a docbook-formatter that implements the formatter interface, and all parsers that use the interface will automatically be supported.{{Citation needed|date=September 2008}}
MoinMoin supports [[Camel case|CamelCase]] linking as well as free links (non-CamelCase linking). The CamelCase is activated by default and MoinMoin does not allow disabling CamelCase links except on a one-off basis. The workaround to do this is to use a different parser<ref>{{cite web|url=https://moinmo.in/ParserMarket/NoCamelCase2 |title=ParserMarket/NoCamelCase2 |publisher=MoinMoin |date=2012-02-08 |access-date=2012-12-06}}</ref> but this option does not work with the [[WYSIWYG]] editor.<ref>{{cite web|url=https://moinmo.in/ParserMarket/NoCamelCase2#Discussion |title=ParserMarket/NoCamelCase2 |publisher=MoinMoin |date=2012-02-08 |access-date=2012-12-06}}</ref>
MoinMoin also has extensive support for [[access-control list]]s (ACL) that greatly increase its usability in a [[content management system]] (CMS). It also has [[Graphical user interface|GUI]] editing capabilities.<ref>{{cite web|url=https://moinmo.in/MoinMoinFeatures#Advanced_Features |title=MoinMoinFeatures |publisher=MoinMoin |date=2009-06-20 |access-date=2012-12-06}}</ref>
MoinMoin is able to either use a built-in search engine (rather slow, but no dependencies) or a [[Xapian]]-based indexed search engine (faster, and can also search old revisions and attached files).<ref>{{cite web|url=https://moinmo.in/HelpOnSearching |title=HelpOnSearching |publisher=MoinMoin |access-date=2012-12-06}}</ref>
MoinMoin also allows synchronization of contents from instance to instance<ref>[https://moinmo.in/WikiSynchronisation WikiSynchronisation] from the MoinMoinWiki.</ref> via [[XML-RPC]], and therefore allows distributed offline editing.
The original MoinMoin "DesktopEdition" is significantly easier to use, because it uses a built-in Web server to display pages, requiring only Python to be installed on the host machine. Since version  1.6.0, the "DesktopEdition" has been integrated into the standard release.<ref name="changelog">{{Citation |title=CHANGES |date=2022-05-08 |url=https://github.com/moinwiki/moin-1.9/blob/fc8fc67a765bc5468795bcfde30561cb7e110bdb/docs/CHANGES |publisher=MoinMoin Wiki Engine |access-date=2022-05-10}}</ref> Also, in this release a different markup syntax was introduced, which had not been changed much since the early releases.<ref name="changelog" />
