Expr-string

Make-expr-string

Basic constructor macro for expr-string structures.

Syntax

(make-expr-string [:strings <strings>] 
                  [:info <info>])

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

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