.\" way too many mistakes in technical documents.

.SH "Name"
.IX Header "Name"
lua-uri-pop \- \s-1POP URI\s0 support for Lua \s-1URI\s0 library
.SH "Description"
.IX Header "Description"
The class \f(CW\*(C`uri.pop\*(C'\fR is used for URIs with the \f(CW\*(C`pop\*(C'\fR scheme.  It inherits
from the uri class.
.PP
\&\s-1POP\s0 URIs with a non-empty path part are considered invalid.  There are also
invalid if there is a userinfo part which has an empty \s-1POP\s0 username or an
empty \s-1POP \s0'auth' type.
.PP
The ';auth=' part of a \s-1POP URI\s0 is normalized so that the word 'auth' is in
lowercase, and if the auth type is the default '*' value then it is removed
altogether, leaving just the username.
.PP
The default port is\ 110.
.SH "Methods"
.IX Header "Methods"
All the methods defined in \fIlua\-uri\fR\|(3) are supported.  The \f(CW\*(C`userinfo\*(C'\fR
method will throw an exception if the new userinfo would form an invalid
\&\s-1POP URI,\s0 and will normalize the auth type part if appropriate.  The \f(CW\*(C`path\*(C'\fR
method will always return empty strings for \s-1POP\s0 URIs, and will throw an
exception if given a new value which is not the empty string.
.PP
The following additional methods are provided:
.IP "uri:pop_user(...)" 4
.IX Item "uri:pop_user(...)"
Get or set the \s-1POP\s0 username, which is stored in the userinfo part of the
authority.
.Sp
The return value will be nil if there is no user information in the \s-1URI,\s0
or a fully decoded string if there is.
.Sp
If the new value is empty, and exception is thrown.  The user can be set to
nil to remove the userinfo part from the \s-1URI,\s0 but this will also throw an
exception if there is an 'auth' type specified.
.IP "uri:pop_auth(...)" 4
.IX Item "uri:pop_auth(...)"
Get or set the \s-1POP\s0 authentication type, which is stored in the userinfo
part of the authority after the string ';auth='.
.Sp
The value returned is just the auth type, not the ';auth=' part, and will be
fully decoded.  The value returned will never be nil.  If there is no auth type
specified then the default value of '*' will be returned.
.Sp
Setting a new value of nil or the empty string will cause an exception
to be thrown.
.SH "References"
.IX Header "References"
This class is based on \*(L"\s-1RFC 2384\*(R"\s0.
