Difference: TWikiTemplates (17 vs. 18)

Edit Template Topics and Variable Expansion

The following variables get expanded when a user creates a new topic based on a template topic:

Variable:	Description:
%DATE%	Current date, e.g. 2025-10-27
%WIKIUSERNAME%	User name, e.g. Main.TWikiGuest
%URLPARAM{"name"}%	Value of a named URL parameter
%NOP%	A no-operation variable that gets removed. Useful to prevent a SEARCH from hitting an edit template topic; also useful to escape a variable like %URLPARAM%NOP%{...}%
%NOP{ ... }%	A no-operation text that gets removed. Useful to write-protect an edit template topic, but not the topics based this template topic. See notes below. Example: %NOP{    * Set ALLOWTOPICCHANGE = Main.TWikiAdminGroup   }%

Notes:

• Unlike other variables, %NOP{ ... }% can span multiple lines.
• The scan for the closing }% pattern is "non-greedy", that is, it stops at the first occurance. That means, you need to escape variables with parameters located inside %NOP{ ... }%: Insert a %NOP% between } and %. Silly example: %NOP{ %GMTIME{"$year"}%NOP%% }%.

All other variables are unchanged, e.g. are carried over "as is" into the new topic.
