HelpOnPageCreation

@DATE@

Current date in the system's format

2004-08-30

@TIME@

Current date and time in the user's format

2004-08-30 06:38:05

@USERNAME@

Just the user's name (or his domain/IP)

TheAnarcat

@USER@

Signature "-- loginname"

-- TheAnarcat 2004-08-30 06:38:05

@MAILTO@

A fancy mailto: link with the user's data

None - on public sites, better use the MailTo macro)

expanding variables

You can use HomePageName/MyDict to expand those variables, just put a WikiDict there with your variables and values. For example, 

 VAR1:: substitution 1
 VAR2:: substitution 2

If you make a page ending with .*Dict (see page_dict_regex), you can set some variables to specific values:

var1
value1
var2
value2
var3
value3

The actual format of the variable assignment above when editing in the edit window is the following: 

 var1:: value1
 var2:: value2
 var3:: value3

The leading space and the space after '::' are important.

getting variables

At Every Page Refresh

You can use these values using the GetVal macro: 

[[GetVal(WikiDict,var1)]] [[GetVal(WikiDict,var2)]] [[GetVal(WikiDict,var3)]]

Renders as:

When Saving the Page

If the variables are set on UserName/MyDict (UserName must of course be replaced as appropriate), you can get the variables when saving any page with @var1@, @var2@, ...etc. instead of the GetVal macro.

/!\ Note that data in dict pages is cached and does not require opening and parsing the page file for each access to the value. In CGI, the value is fetched from a pickle, in long running process, the pickle is loaded once and then the value is accessed from memory.

/!\ Note that saving template pages and using preview does not expand variables. Other than that, variable expansion is very global and happens anywhere on the page, including code displays, comments, processing instructions and other "special" areas of a page you might think are excluded. See HelpOnTemplates for more information about using templates.
