Topic: Coq equivalent to eapply/erewrite
Vincent Siles (Sep 28 2020 at 14:51):
Hi ! I'm slowly getting to know Lean, from a Coq background, and I'm wondering if there's equivalent to Coq's Evar (introduced by eapply/erewrite/refine/ ...) ?

We have erw
and refine
. But I don't know Evar, so I don't know if it's what you are looking for (@Vincent Siles)

It has been a while since I've used Coq, but, as far as I remember, erewrite
/eapply
etc add the existential goals when it can't resolve arguments. As far as my experience goes, Lean's default rw
/apply
mostly behaves like the existential variants in Coq.
