class URIException: object.Exception

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

string decode(Char)(in Char[] encodedURI)

Constraints:
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)

Constraints:
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)

Constraints:
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)

Constraints:
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.

ptrdiff_t uriLength(Char)(in Char[] s)

Constraints:
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!";
writeln(uriLength(s1)); // 49
string s2 = "no uri here";
writeln(uriLength(s2)); // -1
assert(uriLength("issue 14924") < 0);

ptrdiff_t emailLength(Char)(in Char[] s)

Constraints:
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

Examples:

string s1 = "[email protected] with garbage added";
writeln(emailLength(s1)); // 32
string s2 = "no email address here";
writeln(emailLength(s2)); // -1
assert(emailLength("issue 14924") < 0);
