Common Lisp URI parser

The purpose of this project is to create a Common-Lisp library that can build structures, internally representing URIs (Uniform Resource Identifiers), starting from their representations as strings. Parsing requires analyzing and decomposing the input string in sequence, character from character from left to right, in order to build a proper structure that stores its seven components.

An URI is made of "Scheme", "Userinfo, "Host", "Port", "Path", "Query" and "Fragment".

An uri-structure is like this: uri(Scheme, Userinfo, Host, Port, Path, Query, Fragment).

If not specified, in every scheme, 80 is the default port. An empty field, if the URI is still valid, is set to NIL.

If uri-parse is called with an invalid URI-STRING, it returns the following error: "URI is not valid!".

If uri-parse is called with a non-string object, it returns the following error: "URI is not a string!".

Call (uri-parse URI-STRING) in order to get URI structure.

Call (uri-scheme (uri-parse URI-STRING)) in order to get scheme part of URI.

Call (uri-userinfo (uri-parse URI-STRING)) in order to get userinfo part of URI if exists, NIL otherwise.

Call (uri-host (uri-parse URI-STRING)) in order to get host part of URI if exists, NIL otherwise.

Call (uri-port (uri-parse URI-STRING)) in order to get port part of URI if specified (as an Integer), 80 otherwise.

Call (uri-path (uri-parse URI-STRING)) in order to get path part of URI if exists, NIL otherwise.

Call (uri-query (uri-parse URI-STRING)) in order to get query part of URI if exists, NIL otherwise.

Call (uri-fragment (uri-parse URI-STRING)) in order to get fragment part of URI if exists, NIL otherwise.

Call (uri-display (uri-parse URI-STRING)) in order to print on screen (std output) URI fields.

Note that uri-display automatically closes the stream!

Call (uri-display (uri-parse URI-STRING) OutputStream) in order to print on the provided OutputStream URI fields.

Note that uri-display automatically closes the stream!
