(:Summary:variables used when editing pages:)
To set many of the variables below specify them in @@config.php@@.

:$EnableGUIButtons:When set to '1', turns on the graphical buttons in the "Edit Page" form.
-> # turn on graphical edit buttons
-> $EnableGUIButtons = 1;

:$EnablePostAuthorRequired:When set to '1', posting of pages requires the author to provide an author name. Otherwise, authors can post without a name.
-> # require authors to provide a name
-> $EnablePostAuthorRequired = 1;

:$EnableDrafts:When set to '1', enables the "Save draft" button and built-in handling of "draft" versions of pages, where:
## initial "Save draft" of an existing page ("PageName") saves changes to a new name ("PageName-Draft")
## subsequent attempts to edit PageName causes PageName-Draft to be edited
## subsequent selections of "Save draft" cause PageName-Draft to be saved
## pressing "Publish" causes PageName-Draft to be posted to PageName, and deleted.
-> # turn on draft edits
-> $EnableDrafts = 1;

->A related variable, $EnablePublishAttr, adds a new "publish" authorization level to distinguish editing of drafts from publishing them.

:$DraftSuffix:The suffix to use for draft versions of pages (default "-Draft").

:$DiffKeepDays:The $DiffKeepDays variable sets the minimum length of time that a page's revision history is kept. By default it is set to 3650 days, or a little less than ten years. You can change this value in a customization file to be something smaller, e.g.:
-> $DiffKeepDays = 30; # keep revisions at least 30 days
: :Note that a specific page revision isn't removed from the page until the first edit after the time specified by $DiffKeepDays has elapsed. Thus, it's still possible for some pages to have revisions older than $DiffKeepDays -- such revisions will be removed the next time those pages are edited.

:$DeleteKeyPattern:The pattern used to determine if a page should be deleted. The default is to remove pages that contain only the single word "delete" (and optional spaces).
-> # change delete word to "remove"
-> $DeleteKeyPattern = "^\\s*remove\\s*$";
-> # delete any page with no visible text, i.e., empty
-> $DeleteKeyPattern = "^\\s*$";

:$EditTemplatesFmt:Name of the page (or an array of names) to be used as the default text for any newly created pages.
-> [@# Use 'Main.NewPageTemplate' as default text of all new pages
$EditTemplatesFmt = 'Main.NewPageTemplate';
# Use 'Template' in the current group for new pages
$EditTemplatesFmt = '$Group.Template';
# Use 'Template' in the current group if it exists, otherwise
# use 'Main.NewPageTemplate'
$EditTemplatesFmt = array('$Group.Template', 'Main.NewPageTemplate');@]
-> See [[Cookbook:EditTemplates]] for more information.

:$AutoCreate:Used in conjunction with the AutoCreateTargets edit function, this array records any sets of pages which should be created automatically if they don't exist. The syntax is
-> [@$AutoCreate[REGEXP] = PAGE_PARAMETERS;@]
-> where @@REGEXP@@ is a regular expression which will identify the pages to be autocreated, and @@PAGE_PARAMETERS@@ is an array of attributes for the page to be created. For example,
-> [@$AutoCreate['/^Category\\./'] = array('ctime' => $Now);@]
-> will create a blank page with a current creation time for any missing Category page.

:$DefaultPageTextFmt:The text that should be displayed when browsing non-existent pages. As default PmWiki uses the contents of Site.PageNotFound
-> [@$DefaultPageTextFmt = '(:include $[{$SiteGroup}.PageNotFound]:)';@]

:$EditFunctions: This array contains the sequence of functions that are called when a page is edited. It can be customized to provide additional functions to be called as part of the editing process. The standard setting is:
-> [@$EditFunctions = array('EditTemplate', 'RestorePage', 'ReplaceOnSave',
'SaveAttributes', 'PostPage', 'PostRecentChanges', 'AutoCreateTargets', 'PreviewPage'); @]

:$ROEPatterns: With this array you can add a pattern as ''key'' and set a text ''value'' which replace it on every edit request, using preg_replace function. Specifically it is replaced when the page is loaded into the editform, whenever a preview is done, and when the page is saved (from PmWiki 2.2.0beta45). See Cookbook:ROEPatterns for examples.

:$ROSPatterns: With this array you can add patterns as ''key'' and set a text ''value'' which will replace it when the edited page is posted (as signaled by $EnablePost). It is not replaced when the page is loaded into the editform nor when a preview is done, but it is replaced only when the page is saved. See Cookbook:ROSPatterns for examples.

:$IsPagePosted: Set to a true value if the page is actually saved (e.g., this is used to tell the RecentChanges handlers if they need to update).

:$PageEditFmt: By default, this is the HTML to be displayed for an edit form.

:$PageEditForm: Specifies the edit form for ?action=edit. Defaults to '$SiteGroup.EditForm'.

:$HandleEditFmt: Like $HandleBrowseFmt, this specifies the entire output format for ?action=edit for a page.

:$EditRedirectFmt: The page to which an author is sent after pressing "Save" or "Cancel" from an edit form. Defaults to "$FullName", which sends the author to the page just edited, but can be changed to specify another page.
-> [@# redirect to Main.HomePage
$EditRedirectFmt = 'Main.HomePage';
# redirect to HomePage of current group
$EditRedirectFmt = '{$Group}.HomePage';
