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

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.
