uri-common

Description

The uri-common library provides simple and easy-to-use parsing and manipulation procedures for URIs using common schemes.

These "common schemes" all have the following rules:

Library Procedures

Constructors

[procedure] (uri-common-reference string) => uri-common
[procedure] (absolute-uri-common string) => uri-common

Construct a new uri-common object, analogous to uri-reference and absolute-uri from uri-generic.

uri-generic and string representation

[procedure] (uri-common->uri-generic uri-common) => uri-generic
[procedure] (uri-generic->uri-common uri-common #!key (query-separator (form-urlencoded-separator))) => uri-common

To convert between uri-generic and uri-common objects, use these procedures. For information about the optional query-separator argument, see the query encoding/decoding section.

[procedure] (uri-common->string uri-common userinfo) => string

Reconstructs the given URI into a string; uses a supplied function LAMBDA USERNAME PASSWORD -> STRING to map the userinfo part of the URI

Predicates and Accessors

If a component is not defined in the given URI-common, then the corresponding accessor returns #f.

Update the specified keys in the URI-common object in a functional way (ie, it creates a new copy with the modifications).

Reference Resolution

[procedure] (uri-common-relative-to URI URI) => URI

Constructs an absolute URI given a relative URI and a base URI (RFC 3986, Section 5.2.2)

[procedure] (uri-common-relative-from URI URI) => URI

Constructs a new, possibly relative, URI which represents the location of the first URI with respect to the second URI.

Query encoding and decoding

Encode or decode an alist using the encoding corresponding to the form-urlencoded media type, using the given separator character(s).

When encoding, if separator is a string, the first character will be used as the separator in the resulting querystring. If it is a char-set, it will be converted to a string and its first character will be taken. In either case, all of these characters are encoded if they occur inside the key/value pairs.

When decoding, any character in the set (or string) will be seen as a separator.

The separator defaults to the ampersand character.

Normalization

[procedure] (uri-common-normalize-case URI) => URI

URI case normalization (RFC 3986 section 6.2.2.1)

[procedure] (uri-common-normalize-path-segments URI) => URI

URI path segment normalization (RFC 3986 section 6.2.2.3)
