Help and Documentation Utilities

This section describes utilities designed to connect to documentation and to support bug reports. See also scribble/xref.

1 Searching in the Documentation

(require help/search)

package: scribble-lib

procedure
(send-main-page [ #:sub sub
#:notify notify
#:fragment fragment
#:query query]) → any
  sub : path-string? = "index.html"
  notify : (-> (or/c path? string?) void) = void
  fragment : (or/c #f string?) = #f
  query : (or/c #f string?) = #f

Visits the documentation file sub in the user’s browser.

When get-doc-open-url returns #f, send-main-page builds a URL that points into the main collection documentation or into the user-specific documentation, depending on the sub argument. Once it finds the path, send-main-page passes the path to notify. The fragment and query arguments are passed to send-url/file, along with the URL.

When get-doc-open-url returns a URL string, send-main-page appends sub to the URL and passes it to notify. It then appends fragment and query to the URL and passes it on to send-url.

Changed in version 6.0.1.6 of package scribble-lib: Added get-doc-open-url support.

procedure
(perform-search str [context]) → void?
  str : string?
   context :
(or/c #f
      string?
      (list/c string? string?))
= #f

Searches for str in the documentation. The context argument supplies a context for the search or, if it is two strings, a context for the search and a label for that context.

2 Connecting to racket

(require help/help-utils)

package: racket-doc

The help/help-utils library is dynamically loaded by the help form that is available by default in racket.

procedure
(search-for strs) → void?
strs : (listof string?)

Calls perform-search after concatenating the elements of strs and adding spaces between them.

procedure
(find-help/lib id lib) → void?
id : symbol?
lib : module-path?

Visits the documentation page for id as an export of lib.

procedure
(find-help id) → void?
id : identifier?

Visits the documentation for id.

procedure
(go-to-main-page) → void?

Visits the main entry page for the documentation.
