Proof-tree-relation

Change-proof-tree-relation

Modifying constructor for proof-tree-relation structures.

Syntax

(change-proof-tree-relation x 
                            [:asg <asg>] 
                            [:name <name>] 
                            [:args <args>] 
                            [:sub <sub>] 
                            [:asgfree <asgfree>])

This is an often useful alternative to make-proof-tree-relation.

We construct a new proof-tree-relation structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.
