Named view required for list?

[Nils Breunese <n....@vpro.nl>]

Hello all,

I'd like to write a list function to render a database as a CSV file. 
According to the wiki [0] the URL looks like this:

   /<database>/_design/<designdoc>/_list/<list>/<view>

So, a named view is required to run a list function? I'd like to dump 
the complete database to CSV. Of course I could write a simple view 
function that emits all documents, but it would be nice if I could just 
run the list function on the database without using a view.

Is this a technical limitation or design decision? Any ideas on this?

Nils Breunese.

I think we should offer lists on the _all_docs view. It will be a
smallish Erlang patch, if anyone feels like it.

I doubt I'll have time to implement, but this is a feature we'll want
and should be simple to write. If you take it up, please discuss your
progress on the @dev list

We could special-case the _all_docs view, but then, doing it manually is
so simple that I'd rather not add that to core CouchDB (…just yet, if  
there's
more demand for this feature, I'm happy to reconsider :)
