Regex-group

Make-regex-group

Basic constructor macro for regex-group structures.

Syntax

(make-regex-group [:pat <pat>] 
                  [:index <index>])

This is the usual way to construct regex-group structures. It simply conses together a structure with the specified fields.

This macro generates a new regex-group structure from scratch. See also change-regex-group, which can "change" an existing structure, instead.
