I take it back. I never allowed formatters in sections. Nor do I
(currently) allow node-b without the predicate.
So currently, this is what I have working:
{.section node-a} -- predicate function 'true' applied to node-a
{.section node-a predicate?} -- predicate applied to node-a
{.section node-a node-b|predicate?} -- predicate applied to node-b
So my only real addition is that the predicate can be applied to a
different node of the json than is used for the scoping. Another
possible syntax could be:
{.section node-a} -- predicate function 'true' applied to node-a
{.section node-a .if predicate} -- predicate applied to node-a
{.section node-a .if node-b|predicate} -- predicate applied to node-b
or
{.section node-a} -- predicate function 'true' applied to node-a
{.section node-a if:predicate} -- predicate applied to node-a
{.section node-a if:node-b|predicate} -- predicate applied to node-b
or
{.section node-a} -- predicate function 'true' applied to node-a
{.section node-a if predicate} -- predicate applied to node-a
{.section node-a if node-b|predicate} -- predicate applied to node-b
I could do without the | and just use space for the last ones:
{.section node-a node-b predicate?} -- predicate applied to node-b
{.section node-a .if node-b predicate} -- predicate applied to node-b
{.section node-a if:node-b predicate} -- predicate applied to node-b
{.section node-a if node-b predicate} -- predicate applied to node-b
Examples of the last one and letting the predicate function take
params:
{.section <scope> if <predicate-scope> <predicate>}
{.section post if moderator}
{.section post if moderator true}
{.section post if role is "moderator"}
