Subject [jira] Commented: (VELOCITY-623) Modify escape behavior in strict mode
Date Fri, 10 Oct 2008 03:20:47 GMT

    [ https://issues.apache.org/jira/browse/VELOCITY-623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638467#action_12638467

Nathan Bubna commented on VELOCITY-623:
---------------------------------------

Is there any particular reason the escaping has to be related to strict mode?  This is an
improvement, as it shows the user intended to change escaping behavior.  But, could this change
in escaping behavior work even without strict mode on?  Also, what about escaping directives
and macros?

> provides another property 'runtime.references.strict.escape' that when true modifies
the behavior of escaping a reference when in strict mode, see discussion VELOCITY-618.  The
behavior is a as follows:
> $abc = <exception>    -  If $abc is not defined
> \$abc = $abc 
> \\$abc = <exception>  - If $abc is  not defined
> \\\$abc = \$abc
> The backslash in front of a reference always prevents that reference from being evaluated,
and the backslash is removed. This is true wether a reference is in the context or not.
