Templating with multiple revisions

[stouset]

Commands like jj log apply the template to each revision independently. When templating multiple revisions, I might want to do something like "join each revision with a comma and space". The closest I've come is something like this:

jj log --ignore-working-copy --no-graph --revisions @-::@ --template 'change_id.shortest() ++ ", "'
rk, os, 

but that results in an extra separator at the end.

Is there a way to apply a template function like join() between revisions?

No, there isn't right now.

Mercurial has revset() template function, and it could be used conceptually as log -r@ -T 'revset("$1-::$1", commit_id).map(|c| c.change_id().shortest()).join(", ")'. Maybe jj can have something like that.
