Item12381: Configure UI and help text review

General review and cleanup of the configure help text,

-- GeorgeClark - 03 Feb 2013

getRawValue() still expands contained references to $Foswiki::cfg

Example:

$Foswiki::cfg{ScriptUrlPath}/view$Foswiki::cfg{ScriptSuffix}

getRawValue() returns /bin/view

As a consequence the UI doesn't display any Expands to: ... See the defaulf for {ScriptUrlPaths}{view}.

The problem is deeper than getRawValue()

I've changed that code from an eval, do a recursive loop indexing through the keys, with no use of eval. There should be no way for that code to expand the embedded variables.

I think we need to find anyplace where configure uses eval (\$Foswiki::cfg$k) to dynamically access the hash and change it to a loop. Or find some other clever way to step into a hash without use of eval.

I've traced it specifically to the Configure::Query::_getSetParams(). When it does the eval to set the key, it expands it.

Yea that seems to be a good idea. For now I get lots of errors of the form

Use of uninitialized value in string at (eval 20898) line 1.

presumably as a consequence of $k not being defined sometimes.

No, getRaw was failing for undefined keys that have spec. No need to do an assignment, just return the undef. fixed.
