Implements Uniform Resource Identifiers (URI) as described in RFC 2396.
Returns a Uniform Resource Identifier string from component arguments.
Returns a URI string combining the components of list path.
Returns a string which defines this location in the (HTML) file as name. The hypertext ‘<A HREF="#name">’ will link to this point.
(html:anchor "(section 7)") ⇒ "<A NAME=\"(section%207)\"></A>"
Returns a string which links the highlighted text to uri.
(html:link (make-uri "(section 7)") "section 7") ⇒ "<A HREF=\"#(section%207)\">section 7</A>"
Returns a string specifying the base uri of a document, for inclusion in the HEAD of the document (see head).
Returns a string specifying the search prompt of a document, for inclusion in the HEAD of the document (see head).
Returns a list of 5 elements corresponding to the parts (scheme authority path query fragment) of string uri-reference. Elements corresponding to absent parts are #f.
The path is a list of strings. If the first string is empty,
then the path is absolute; otherwise relative. The optional base-tree is a
tree as returned by
uri->tree; and is used as the base address for relative
If the authority component is a Server-based Naming Authority, then it is a list of the userinfo, host, and port strings (or #f). For other types of authority components the authority will be a string.
(uri->tree "http://www.ics.uci.edu/pub/ietf/uri/#Related") ⇒ (http "www.ics.uci.edu" ("" "pub" "ietf" "uri" "") #f "Related")
Returns a list of txt split at each occurrence of chr. chr does not appear in the returned list of strings.
Converts a URI encoded query-string to a query-alist.
uric: prefixes indicate procedures dealing with
Returns a copy of the string uri-component in which all unsafe octets
(as defined in RFC 2396) have been ‘%’ escaped.
uric:decode decodes strings encoded by
Returns a copy of the string uri-component in which each ‘%’ escaped characters in uri-component is replaced with the character it encodes. This routine is useful for showing URI contents on error pages.
path-list is a path-list as returned by
returns a list of items returned by
to types ptypes.
Returns a URI-string for path on the local host.
Returns #t if str is an absolute-URI as indicated by a syntactically valid (per RFC 2396) scheme; otherwise returns #f.
Returns #t if file-name is a fully specified pathname (does not depend on the current working directory); otherwise returns #f.
Returns #t if changing directory to str would leave the current directory unchanged; otherwise returns #f.
Returns #t if the string str contains characters used for specifying glob patterns, namely ‘*’, ‘?’, or ‘[’.
Before RFC 2396, the File Transfer Protocol (FTP) served a similar purpose.
Returns a list of the decoded FTP uri; or #f if indecipherable. FTP Uniform Resource Locator, ange-ftp, and getit formats are handled. The returned list has four elements which are strings or #f:
