This is a slightly different approach that I've used before. The names are
all fetched in a form where they can be wikified, turned back into a list,
and then sorted. Then a lookup is done by name for each item and the
project is extracted. I think from this you can see how you would proceed
with extracting the URL as well. For this to work of course, the names have
to be unique. I called the data tiddler "data" here.
\define getnames() <$vars lb=" [[" rb="]]" sep="$$"><$list
filter="[[data]indexes[]addsuffix[/name]]" variable="fetch">{{{
[[data]getindex<fetch>addprefix<lb>addsuffix<rb>] }}}</$list></$vars>
\define getprojectbyname(name)
<$list filter="[[data]indexes[]]" variable="index">
<$list filter="[<index>addsuffix[/name]]" variable=namepath>
<$list filter="[[data]getindex<namepath>compare:string:eq<__name__>]">
<$list filter="[<index>addsuffix[/project]]" variable=projectpath>
{{{ [[data]getindex<projectpath>] }}}
</$list></$list></$list></$list>
\end
<$wikify text="""<<getnames>>""" name="names">
<$list filter="[enlist<names>sort[]]" variable="name">
Name: <<name>> <br/>
Project: <$macrocall $name="getprojectbyname" name=<<name>> /> <br/><br/>
</$list>
</$wikify>
I've often thought how handy it would be if you could get two outputs from
a list instead of just one. e.g. both and index and the index/name value.
