Will Glass-Husain updated VELOCITY-395:
---------------------------------------
Bugzilla Id: (was: 35738)
Fix Version: 1.6
> Semantics of escaping unclear
> -----------------------------
>
> Key: VELOCITY-395
> URL: http://issues.apache.org/jira/browse/VELOCITY-395
> Project: Velocity
> Type: Improvement
> Components: Documentation
> Versions: 1.3.1
> Environment: Operating System: Windows 2000
> Platform: PC
> Reporter: Frank Fischer
> Priority: Minor
> Fix For: 1.6
>
> I think the semantics of the escaping operator \ (backslash) are not
> documented
> clearly. Especially I miss this ones:
> Why generates
> \$foo ==> $foo
> but
> \${foo} ==> \${foo}
> this seems inconsistent to me. I expect
> \${foo} ==> ${foo}
> I understand that
> ${foo:bar}
> raises an error since there are no : (colons)
> allowed in a variable-name.
> But why raises
> \${foo:bar}
> also an error? I would expect that \$ disables the function of $
> as an operator, so that the following {..} will not be parsed as
> a variable name.
> There should be a simple way to generate something like
> ${foo:bar}
> or even
> ${not a variable name at all &%$}
> The workaround
> #set($D='$')
> ${D}{foo:bar}
> is undocumented and REALLY ugly.
