Regex-charset

Make-regex-charset

Basic constructor macro for regex-charset structures.

Syntax

(make-regex-charset [:chars <chars>] 
                    [:negp <negp>])

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

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

Definition

                       nil))
