#### 6.15`` API for Cross-References for Installed Manuals🔗ℹ

(require setup/xref) | package: racket-index

> procedure (load-collections-xref [on-load]) → xref?
> on-load : (-> any/c) = (lambda () (void))

Either creates and caches or returns a cached cross-reference record created with make-collections-xref. The on-load function is called only when a previously cached record is not returned.

> > procedure
> > (make-collections-xref |
> > | [ | #:no-user? no-user? |
> > |  | #:no-main? no-main? |
> > |  | #:doc-db db-path |
> > |  | #:quiet-fail? quiet-fail? |
> > |  | #:register-shutdown! register-shutdown!]) |
> → xref?
> no-user? : any/c = #f
> no-main? : any/c = #f
> db-path : (or/c #f path?) = #f
> quiet-fail? : any/c = #f
> register-shutdown! : ((-> any) . -> . any) = void

Like load-xref, but automatically finds all cross-reference files for manuals that have been installed with raco setup. The resulting cross-reference record takes advantage of a cross-reference database db-path, when support is available, to delay the loading of cross-reference details until needed.

Cross-reference information is skipped when it is installed in the main installation or in a user-specific location, respectively, if no-main? or no-user? is #t.

If quiet-fail? is true, then errors are suppressed while loading cross-reference information.

The register-shutdown! callback may be called to register a function that closes database connections when the result of make-collections-xref is no longer needed. If register-shutdown! is not supplied or if a function sent to register-shutdown! is never called, database connections will be closed only though a custodian.

> > procedure
> > (get-rendered-doc-directories |  | no-user? |  |  |  |
> > |  | no-main?) |  | → |  | (listof path?)
> no-user? : any/c
> no-main? : any/c

Returns a list of directories for all documentation for all installed collections, omitting documentation that is installed in the main installation or in a user-specific location, respectively, if no-main? or no-user? is #t.

> procedure (get-current-doc-state) → doc-state?

Records the time stamps of files that are touched whenever the documentation is changed.

Added in version 1.2 of package racket-index.

> procedure (doc-state-changed? doc-state) → boolean?
> doc-state : doc-state?

Returns #t when the time stamps of the files in doc-state changed (or new files appeared) and #f otherwise.

If the result is #t, then the documentation in this installation of Racket has changed and otherwise it hasn’t.

Added in version 1.2 of package racket-index.

> procedure (doc-state? v) → boolean?
> v : any/c

A predicate to recognize the result of get-current-doc-state.

Added in version 1.2 of package racket-index.
