#### 6.13`` API for Platform Specifications

(require setup/matching-platform) | package: base

Added in version 6.0.1.13 of package base.

> procedure (platform-spec? v) → boolean?
> v : any/c

Returns #t if v is a symbol, string, or regexp value (in the sense of regexp?), #f otherwise.

> > procedure
> > (matching-platform? |  | spec |
> > | [ | #:cross? cross? |
> > |  | #:system-type sys-type |
> > |  | #:system-library-subpath sys-lib-subpath]) |
> → boolean?
> spec : platform-spec?
> cross? : any/c = #f
> | sys-type |  | : |  | (or/c #f symbol?) |  | = |  |
> (if cross?
> (cross-system-type)
> (system-type))
> | sys-lib-subpath |  | : |  | (or/c #f path-for-some-system?)
> |  |  | = |  |
> (if cross?
> (cross-system-library-subpath #f)
> (system-library-subpath #f))

Reports whether spec matches sys-type or sys-lib-subpath, where #f values for the latter are replaced with the default values.

If spec is a symbol, then the result is #t if sys-type is the same symbol, #f otherwise.

If spec is a string, then the result is #t if (path->string sys-lib-subpath) is the same string, #f otherwise.

If spec is a regexp value, then the result is #t if the regexp matches (path->string sys-lib-subpath), #f otherwise.

Changed in version 6.3 of package base: Added #:cross? argument and changed the contract on sys-lib-subpath to accept path-for-some-system? instead of just path?.
