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 normally is located besides your moin.cgi driver script. If you need to make a custom install, it can be located anywhere, but you must add the path to the directory where it is located to your Python system path in your server script. See the "System Path Configuration" section in your server script.

Wiki configuration file structure

General notes on wiki/farmconfig.py structure:

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

from MoinMoin.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...

Unicode options

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.

Notes:

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 (international users might want to change them):

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

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. Internally, moin adds a catch all ('wikiconfig', '.*') to the end of that list, so you do not need something like this in farmconfig.wikis.

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).

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

Explanation:

# -*- coding: iso-8859-1 -*-
# wikiconfig.py:
from farmconfig import FarmConfig
class Config(FarmConfig):
    show_hosts = 0
    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 all 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.

Special options

Default front page

The default front page name, "FrontPage", is automatically translated into the user language. Thus, an English user will end up at FrontPage, while a French user will end up at PageD'Accueil.

So you have 2 choices for your site:

  1. You will have a single language site, with a single language front page. Then just make your own single front page (and don't name it FrontPage) which is suitable for all people regardless of their native language and set the page_front_page setting to this name. For example:

     page_front_page = u'MyGreatProject'
    
  2. You will have a multiple language site and you intend to speak the user's language (or at least some of those languages). In that case, just edit FrontPage to fit your needs. Also edit all the translations of FrontPage (like {de} StartSeite) you want to support (and keep them all in sync). If you don't want (or cannot) support a specific language, then replace that translation by a redirect to e.g. the english FrontPage:

     #redirect FrontPage
    

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.
