Item8244: BreadCrumbsPlugin should expand ", needs a new pseudo-variable

The following doesn't work as with other formatted strings:

%BREADCRUMBS{"RootWeb/OtherWeb/SubWeb.SomeTopic" format=""""}%

Expected: "" in each expanded breadcrumb, but instead shows "".

Also, I needed a way to tell if I was expanding a parent web (other than the web where the breadcrumbs were being expanded). So I added a pseudo-variable, $webpart.

Also, there is a pseudo-variable available ($web) which is not documented.

I've attached a patch and the following lines should be added to the pseudo-variables documentation in the BreadCrumbsPlugin topic:

• $web: the web where the %BREADCRUMBS% macro is being expanded.
• $webpart: when processing a breadcrumb that is a parent web, expands to the name of that parent web.

Thanks Paul for the patch. I'll look into what you are trying to achieve. Btw. " isn't really needed. Try \" instead.

Whoops. I am sorry Michael, somehow I got my $ and " mixed up. The BreadCrumbsPlugin topic does not actually document a $ variable. I just fixed up this bug report to reflect that I was mistaken. I suppose I shouldn't be debugging in the car on long trips!

The reason I was looking for " was because I was using an IF{} in the format string (as I would with other FormattedSearch strings).

As for the $webpart variable, I do an IF as follows: %IF{"'$webpart'!='$web'" then="<parent web formatting>" else="<current web formatting>"}%. Perhaps this could be avoided with the provision of a new format string (different format strings for parent vs current webs), but even here I feel $webpart could still be useful.

Actually the correct fix is to expand $web to the web part of the $webtopic variable and $topic to the topic part. The former value of $web was pretty pointless as it always expanded to BASEWEB. So your IF expression should actually be %IF{"'$webpart'!=$BASEWEB" then="<parent web formatting>" else="<current web formatting>"}%

I won't add " as that is redundant a legacy way of writing \". Use %BREADCRUMBS{"RootWeb/OtherWeb/SubWeb.SomeTopic" format="\"\""}% instead.

We fixed behaviour for $web but not for $topic. This next commit makes BreadCrumbsPlugin behave as described with the updated notes about these pseudo-vars.

Michael, hope you don't mind me making this commit for you. Let me know if you'd rather I didn't commit any one-line fixes like this in future.

That's okay. I trust your instincts to spot'n fix bugs.
