+ <description>
+ <p>This module contains functions for parsing and handling URIs
+ (<url href="https://www.ietf.org/rfc/rfc3986.txt">RFC 3986</url>).
+ </p>
+ <p>A URI is an identifier consisting of a sequence of characters matching the syntax
+ rule named <em>URI</em> in <url href="https://www.ietf.org/rfc/rfc3986.txt">RFC 3986</url>.
+ </p>
+ <p> The generic URI syntax consists of a hierarchical sequence of components referred
+ to as the scheme, authority, path, query, and fragment:</p>
+ <pre>
+ URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
+ hier-part = "//" authority path-abempty
+ / path-absolute
+ / path-rootless
+ / path-empty
+ scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )
+ authority = [ userinfo "@" ] host [ ":" port ]
+ userinfo = *( unreserved / pct-encoded / sub-delims / ":" )
+
+ reserved = gen-delims / sub-delims
+ gen-delims = ":" / "/" / "?" / "#" / "[" / "]" / "@"
+ sub-delims = "!" / "$" / "&amp;" / "'" / "(" / ")"
+ / "*" / "+" / "," / ";" / "="
+
+ unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
+ </pre><br></br>
+ <p>The interpretation of a URI depends only on the characters used and not on how those
+ characters are represented in a network protocol.</p>
+ <p>The functions implemented by this module cover the following use cases:</p>
+ <list type="bulleted">
+ <item>Parsing URIs into its components and returing a map<br></br>
+ <seealso marker="#parse/1"><c>parse/1</c></seealso>
+ </item>
+ <item>Recomposing a map of URI components into a URI string<br></br>
+ <seealso marker="#recompose/1"><c>recompose/1</c></seealso>
+ </item>
+ <item>Changing inbound binary and percent-encoding of URIs<br></br>
+ <seealso marker="#transcode/2"><c>transcode/2</c></seealso>
+ </item>
+ <item>Transforming URIs into a normalized form<br></br>
+ <seealso marker="#normalize/1"><c>normalize/1</c></seealso>
+ </item>
+ </list>
+ <p>There are four different encodings present during the handling of URIs:</p>
+ <list type="bulleted">
+ <item>Inbound binary encoding in binaries</item>
+ <item>Inbound percent-encoding in lists and binaries</item>
+ <item>Outbound binary encoding in binaries</item>
+ <item>Outbound percent-encoding in lists and binaries</item>
+ </list>
+ <p>Functions with <c>uri_string()</c> argument accept lists, binaries and
+ mixed lists (lists with binary elements) as input type. All of the functions but
+ <c>transcode/2</c> expects input as lists of unicode codepoints, UTF-8 encoded binaries
+ and UTF-8 percent-encoded URI parts ("%C3%B6" corresponds to the unicode character "ö").</p>
+ <p>Unless otherwise specified the return value type and encoding are the same as the input
+ type and encoding. That is, binary input returns binary output, list input returns a list
+ output but mixed input returns list output.</p>
+ <p>In case of lists there is only percent-encoding. In binaries, however, both binary encoding
+ and percent-encoding shall be considered. <c>transcode/2</c> provides the means to convert
+ between the supported encodings, it takes a <c>uri_string()</c> and a list of options
+ specifying inbound and outbound encodings.</p>
+ <p><url href="https://www.ietf.org/rfc/rfc3986.txt">RFC 3986</url> does not mandate any specific
+ character encoding and it is usually defined by the protocol or surrounding text. This library
+ takes the same assumption, binary and percent-encoding are handled as one configuration unit,
+ they cannot be set to different values.</p>
+ </description>
+
+ <datatypes>

+%%
+%%
+%% [RFC 3986, Chapter 2.3. Unreserved Characters]
+%%
+%% unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
+%%
+%%
+%% [RFC 3986, Chapter 3. Syntax Components]
+%%
+%% The generic URI syntax consists of a hierarchical sequence of
+%% components referred to as the scheme, authority, path, query, and
+%% fragment.
+%%
+%% URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
+%%
+%% hier-part = "//" authority path-abempty
+%% / path-absolute
+%% / path-rootless
+%% / path-empty
+%%
+%% The scheme and path components are required, though the path may be
+%% empty (no characters). When authority is present, the path must
+%% either be empty or begin with a slash ("/") character. When
+%% authority is not present, the path cannot begin with two slash
+%% characters ("//"). These restrictions result in five different ABNF
+%% rules for a path (Section 3.3), only one of which will match any
+%% given URI reference.
+%%
+%% The following are two example URIs and their component parts:
+%%
+%% foo://example.com:8042/over/there?name=ferret#nose
+%% \_/ \______________/\_________/ \_________/ \__/
+%% | | | | |
+%% scheme authority path query fragment
+%% | _____________________|__
+%% / \ / \
+%% urn:example:animal:ferret:nose
+%%
+%%
+%% [RFC 3986, Chapter 3.1. Scheme]
+%%
+%% Each URI begins with a scheme name that refers to a specification for
+%% assigning identifiers within that scheme.
+%%
+%% scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )
+%%
+%%
+%% [RFC 3986, Chapter 3.2. Authority]
+%%
+%% Many URI schemes include a hierarchical element for a naming
+%% authority so that governance of the name space defined by the
+%% remainder of the URI is delegated to that authority (which may, in
+%% turn, delegate it further).
+%%
+%% authority = [ userinfo "@" ] host [ ":" port ]
+%%
+%%
+%% [RFC 3986, Chapter 3.2.1. User Information]
+%%
+%% The userinfo subcomponent may consist of a user name and, optionally,
+%% scheme-specific information about how to gain authorization to access
+%% the resource. The user information, if present, is followed by a
+%% commercial at-sign ("@") that delimits it from the host.
+%%
+%% userinfo = *( unreserved / pct-encoded / sub-delims / ":" )
+%%
+%%
+%% [RFC 3986, Chapter 3.2.2. Host]

+%% number in decimal following the host and delimited from it by a
+%% single colon (":") character.
+%%
+%% port = *DIGIT
+%%
+%%
+%% [RFC 3986, Chapter 3.3. Path]
+%%
+%% The path component contains data, usually organized in hierarchical
+%% form, that, along with data in the non-hierarchical query component
+%% (Section 3.4), serves to identify a resource within the scope of the
+%% URI's scheme and naming authority (if any). The path is terminated
+%% by the first question mark ("?") or number sign ("#") character, or
+%% by the end of the URI.
+%%
+%% path = path-abempty ; begins with "/" or is empty
+%% / path-absolute ; begins with "/" but not "//"
+%% / path-noscheme ; begins with a non-colon segment
+%% / path-rootless ; begins with a segment
+%% / path-empty ; zero characters
+%%
+%% path-abempty = *( "/" segment )
+%% path-absolute = "/" [ segment-nz *( "/" segment ) ]
+%% path-noscheme = segment-nz-nc *( "/" segment )
+%% path-rootless = segment-nz *( "/" segment )

+%% ; non-zero-length segment without any colon ":"
+%%
+%% pchar = unreserved / pct-encoded / sub-delims / ":" / "@"
+%%
+%%
+%% [RFC 3986, Chapter 3.4. Query]
+%%
+%% The query component contains non-hierarchical data that, along with
+%% data in the path component (Section 3.3), serves to identify a
+%% resource within the scope of the URI's scheme and naming authority
+%% (if any). The query component is indicated by the first question
+%% mark ("?") character and terminated by a number sign ("#") character
+%% or by the end of the URI.
+%%
+%% query = *( pchar / "/" / "?" )
+%%
+%%
+%% [RFC 3986, Chapter 3.5. Fragment]
+%%
+%% The fragment identifier component of a URI allows indirect
+%% identification of a secondary resource by reference to a primary
+%% resource and additional identifying information.
+%%
+%% fragment = *( pchar / "/" / "?" )
+%%
+%%
+%% [RFC 3986, Chapter 4.1. URI Reference]
+%%
+%% URI-reference is used to denote the most common usage of a resource
+%% identifier.
+%%
+%% URI-reference = URI / relative-ref
+%%
+%%
+%% [RFC 3986, Chapter 4.2. Relative Reference]
+%%
+%% A relative reference takes advantage of the hierarchical syntax
+%% (Section 1.2.3) to express a URI reference relative to the name space
+%% of another hierarchical URI.
+%%
+%% relative-ref = relative-part [ "?" query ] [ "#" fragment ]
+%%
+%% relative-part = "//" authority path-abempty
+%% / path-absolute
+%% / path-noscheme
+%% / path-empty
+%%
+%%
+%% [RFC 3986, Chapter 4.3. Absolute URI]
+%%
+%% Some protocol elements allow only the absolute form of a URI without
+%% a fragment identifier. For example, defining a base URI for later
+%% use by relative references calls for an absolute-URI syntax rule that
+%% does not allow a fragment.
+%%
+%% absolute-URI = scheme ":" hier-part [ "?" query ]
