This page describes various terms related to PmWiki.
- Configuration file
-  A specially-named PHP script file where local customizations can take place for a farm, a wiki, a group, or a page.
- Default configuration
-  The way Pm has chosen to set all settings, or an individual setting, by default.  For example, $EnablePathInfois disabled by default.  A wiki with no local/config.php file is using the default configuration.  Likewise, a farm that only defines$FarmPubDirUrlin farmconfig.php is using the default configuration.
- Farm
-  A group of wikis that share code. Content and formats may or may not be shared. For more farm-related terms, including several which have been deprecated, see WikiFarmTerminology
- Farm-wide configuration file
-  A WikiFarm's local/farmconfig.php file, where any settings (besides $FarmPubDirUrl) customize the default configuration for all of the wikis in a farm.
- Full page name
-  The full page name consists of a group and a name, e.g. Main.WikiSandbox. The variable for the full page name is{$FullName}, which for this page isPmWiki.Glossary. Similarly, the variable for the group is{$Group}which here isPmWiki.
- Local configuration file
-  A specially-named PHP script where local customizations can take place for an individual wiki.  For an entire wiki it's named local/config.php.  Individual groups and pages can also have their own local configuration files.
- Local customization
-  Any deviation from the default configuration.  A related phrase is "farm-wide customization".
- Page file name
-  The page file name is the name of the file that normally stores the data of a page in the directory wiki.d/. This file name is normally built directly from the page name.
- Page link
-  A page link is something that is used to generate a link to a page. For example, the markup [[wiki sandbox]],[[(wiki) sandbox]],WikiSandbox,Main/WikiSandbox,[[Main/wiki sandbox]],[[Main.WikiSandbox | click here]], etc all specify a link to the page 'Main.WikiSandbox'.  In each case PmWiki uses the context of the link to generate a page name from the page link -- normally by capitalizing each word found in the link and stripping any characters that aren't considered valid in page names.
- Page name
-  The page name is a string that PmWiki uses to refer to a page - i.e. it names the page. This could also be considered a handle for the page. The variable for the page name is simply called {$Name}, which for this page isGlossary.
Note that there is no whitespace in page names, and by default PmWiki capitalizes each word in a page's name. There is however a variable {$Namespaced} where spaces have been inserted, e.g. for the page WikiSandbox this variable would be Wiki Sandbox.
Note that PmWiki also uses the page name to locate per-group and per-page customization files in the local/ subdirectory. For example, browsing Main.WikiSandbox would cause local/Main.WikiSandbox.php and local/Main.php to be loaded if these files existed.
- Page title
-  A page title is the title element of a page, i.e. what is usually shown above the page and in the browser window's name. This title is normally set via the directive (:title:), but if no such directive is given the title will be automatically generated from the page name. The title of a page is accessed via either the variable{$Title}or the variable{$Titlespaced}. The latter differs in that it uses the spaced version of the name.
- Page URI
-  Page names are used in URIs to tell PmWiki which page is to be loaded or acted upon. The normal form of a page URI is usually one of these two
http://www.example.com/pmwiki/pmwiki.php?n=Main.WikiSandbox
 http://www.example.com/pmwiki/pmwiki.php/Main.WikiSandbox
 
Note that various aliasing and rewriting tricks can be used to modify this, but PmWiki expects to obtain a page name from the parameter 'n' or from the PATH_INFO component following the URI of the script (pmwiki.php).
Note that the parameter 'n' takes precedence over PATH_INFO if both are available.
