class URIException: object.Exception;

This Exception is thrown if something goes wrong when encoding or decoding a URI.

string decode(Char)(in Char[] encodedURI) if (isSomeChar!Char);

Decodes the URI string encodedURI into a UTF-8 string and returns it. Escape sequences that resolve to reserved URI characters are not replaced. Escape sequences that resolve to the '#' character are not replaced.

string decodeComponent(Char)(in Char[] encodedURIComponent) if (isSomeChar!Char);

Decodes the URI string encodedURI into a UTF-8 string and returns it. All escape sequences are decoded.

string encode(Char)(in Char[] uri) if (isSomeChar!Char);

Encodes the UTF-8 string uri into a URI and returns that URI. Any character not a valid URI character is escaped. The '#' character is not escaped.

string encodeComponent(Char)(in Char[] uriComponent) if (isSomeChar!Char);

Encodes the UTF-8 string uriComponent into a URI and returns that URI. Any character not a letter, digit, or one of -.!~*'() is escaped.

size_t uriLength(Char)(in Char[] s) if (isSomeChar!Char);

Does string s[] start with a URL?

Returns:

-1 it does not len it does, and s[0..len] is the slice of s[] that is that URL

Examples:

string s1 = "http://www.digitalmars.com/~fred/fredsRX.html#foo end!";
assert (uriLength(s1) == 49);
string s2 = "no uri here";
assert (uriLength(s2) == -1);

size_t emailLength(Char)(in Char[] s) if (isSomeChar!Char);

Does string s[] start with an email address?

Returns:

-1 it does not len it does, and s[0..i] is the slice of s[] that is that email address

References: RFC2822

Examples:

string s1 = "[email protected] with garbage added";
assert (emailLength(s1) == 32);
string s2 = "no email address here";
assert (emailLength(s2) == -1);
