This page should help you with configuring an already installed MoinMoin wiki.


1. Character Set

Moin uses Unicode internally, and utf-8 for external output and input, like pages, HTML output and translation files. The external character set is defined in config.charset to utf-8. This setting is fine for all languages, as any character can be encoded in UTF-8. You should not change this value, although technically it is possible.

Certain options must use Unicode values. For example, the site name could contain German umlauts or French accents or be in Chinese or Hebrew. Because of this, you must use unicode strings for those items. Unicode strings are defined by prefixing the letter u to the string. Here are some examples:

    # Site name, used by default for wiki name-logo [Unicode]
    sitename = u"Jürgen's Wiki"
    # another example:
    sitename = u'הוויקי של יורגן'

Read the comments in the configuration file - they tell you which options must use Unicode values.


2. International Setup

The default configuration file shipped with moin uses iso-8859-1 coding. This is fine for Latin languages like English or German, but not usable for non-latin languages. If you want to have non-latin characters in your configuration items, use utf-8 coding for the config file.

Set the first line of all configuration files to this line:

# -*- coding: utf-8 -*-

Values using unicode strings can be recognized by their default value being u"...." or ur"..." (the u means unicode) or when the description explicitly tells [unicode].

For ready made configuration in your language, see ConfigMarket. Read also the section about unicode options.

3. Customization of user preferences

You can predefine, disable or remove several options in the user preferences, see HelpOnConfiguration/UserPreferences.

Configuring a single wiki

If you run a single wiki, you should not copy the file farmconfig.py into your configuration directory (remove it and the .pyc file, if it is there). Without farmconfig, moin uses the default wikiconfig.py.

wikiconfig.py can be located anywhere, you just have make sure it can be imported by moin - it is a good idea to add the directory where it resides as first element to sys.path (this is the list of pathes python uses when searching for importable stuff). sys.path setup is done early, usually in the server adaptor script you use (e.g. moin.cgi or moin.wsgi) - see the comments in the script for details.

General notes on wiki/farmconfig.py structure:

# -*- coding: iso-8859-1 -*-

from MoinMoin.config.multiconfig import DefaultConfig

class Config(DefaultConfig):

    sitename = u'MyWiki'   # u means that it will be converted to Unicode
    interwikiname = 'MyWiki'
    data_dir = '/where/ever/mywiki/data/'
    underlay_dir = '/where/ever/mywiki/underlay/'
    # More settings follow...

Configuration of multiple wikis

The moinmoin wiki engine is capable of handling multiple wikis using a single installation, a single set of configuration files and a single server process. Especially for persistent environments like Twisted, this is necessary, because the Twisted server will permanently run on a specific IP address and TCP port number. So for virtual hosting of multiple domains (wikis) on the same IP and port, we need the wiki engine to permanently load multiple configs at the same time and choose the right of them when handling a request for a specific URL.

To be able to choose the right config, moin uses config variable wikis located in the file farmconfig.py - it simply contains a list of pairs (wikiname, url-regex). Please only use valid python identifiers for wikiname (to be exact: identifier ::= (letter|"_") (letter | digit | "_")* - just try with a simple word if you didn't understand that grammar rule). When processing a request for some URL, moin searches through this list and tries to match the url-regex against the current URL. If it doesn't match, it simply proceeds to the next pair. If it does match, moin loads a configuration file named <wikiname>.py (usually from the same directory) that contains the configuration for that wiki.

farmconfig.py in the distribution archive has some sample entries for a wiki farm running multiple wikis. You need to adapt it to match your needs if you want to run multiple wikis.

/!\ For simpler writing of these help pages, we will call such a <wikiname>.py configuration file simply wikiconfig.py, of course you have to use the filename you chose.

Of course you have already adapted the wikis setting in farmconfig.py (see above), so we only give some hints how you can save some work. Please also read the single wiki configuration hints, because it explains config inheritance.

We now use the class-based configuration to be able to configure the common settings of your wikis at a single place: in the base configuration class (see farmconfig.py for an example):


# -*- coding: iso-8859-1 -*-
# farmconfig.py:
from MoinMoin.config.multiconfig import DefaultConfig
class FarmConfig(DefaultConfig):
    url_prefix = '/wiki'
    show_hosts = True
    underlay_dir = '/where/ever/common/underlay'
    # ...

The configs of your individual wikis then only keep the settings that need to be different (like the logo, or the data directory or ACL settings). Everything else they get by inheriting from the base configuration class, see moinmaster.py for a sample.


# -*- coding: iso-8859-1 -*-
# moinmaster.py:
from farmconfig import FarmConfig
class Config(FarmConfig):
    show_hosts = False
    sitename = u'MoinMaster'
    interwikiname = 'MoinMaster'
    data_dir = '/org/de.wikiwikiweb.moinmaster/data/'
    # ...

Overview of Configuration Options

The following table contains default values and a short description for most configuration variables. Most of these can be left at their defaults, those you need to change with every installation are listed in the sample wikiconfig.py that comes with the distribution.

(!) You can also have a look at MoinMoin/config/multiconfig.py, class DefaultConfig for further information (that file has the builtin default configuration).

ucs-2 lowercase letters

Lowercase letters, used to define what is a WikiName



a list of smiley markups moin supports - image and image sizes are defined in the theme code.



umask used by moin, the default gives rights to owner and group, but not to world.
