I'm having problems defining custom variables on a page following the
instructions in HelpOnVariables. I think there is definitely a doc bug
in there; that page is not very clear on what is possible, never mind
how to do it.
First: from the wording in HelpOnVariables, it's not even clear that I
*can* define custom variables. The section header "Expanding Variables"
is ambiguous: to most programmers, "expanding" a variable means, for
example, replacing "@USERNAME@" with "gward". But it's also possible
for it to mean "expand the set of variables by defining new ones". That
is kind of what it sounds like. If so, I would suggest rewriting this
section as:
"""
== Defining New Variables ==
You can add your own custom variables to any page. Just create a new sub-page
called `MyDict` and enter a dictionary of custom variables there (see
HelpOnDictionaries). For example, to add variables `REVIEWER` and
`REVIEW_DATE` to `MyPage`, create `MyPage/MyDict` and give it content like
{{{
REVIEWER:: JohnDoe
REVIEW_DATE:: 2008-10-20
}}}
"""
Is that correct?
Second: if that *is* correct, it doesn't seem to work in 1.8.0rc1. At
any rate, I have created a "/MyDict" subpage and am unable to access
those variable values using <<GetVal()>>. Is there a working example of
this feature somewhere?
Thanks --
Greg
