@subsection{Additional @scheme[require] and @scheme[provide] Macros}
@note-lib-only[scheme/modspec-forms]
This library provides additional forms for use in @scheme[require] and
@scheme[provide]. These forms provide more complex selection and
massaging of identifiers that are useful in some cases. Note that a
@scheme[require] form is expanded before it is used, which means that
requiring the library itself should be a separate form. For example, use
@schemeblock[
(require scheme/modspec-forms)
(require (matching-identifiers-in #rx"foo" "foo.ss"))
]
instead of
@schemeblock[
(require scheme/modspec-forms
(matching-identifiers-in #rx"foo" "foo.ss"))
]
@defsubform[(matching-identifiers-in regexp require-spec)]{
Like @scheme[require-spec], but including only exports whose names
match @scheme[regexp]. @scheme[regexp] must be a literal regular
expression (see @secref["regexp"]).}
