.\" way too many mistakes in technical documents.

.SH "Name"
.IX Header "Name"
lua-uri-ftp \- \s-1FTP URI\s0 support for Lua \s-1URI\s0 library
.SH "Description"
.IX Header "Description"
The class \f(CW\*(C`uri.ftp\*(C'\fR is used for URIs with the \f(CW\*(C`ftp\*(C'\fR scheme.  It inherits from
the uri._login class.
.PP
\&\s-1FTP\s0 URIs with a missing authority part or an empty host part are considered
to be invalid.  An empty path is always normalized to '/'.  The default port
is\ 21.
.SH "Methods"
.IX Header "Methods"
All the methods defined in \fBlua\-uri\fR\|(3) and \fBlua\-uri\-_login\fR\|(3) are
supported, in addition to the following:
.IP "uri:ftp_typecode(...)" 4
.IX Item "uri:ftp_typecode(...)"
Mutator for the 'type' parameter at the end of the path.  If the optional
argument is supplied then a new type is set, replacing the existing one, or
causing the type parameter to be added to the path if it isn't there already.
.Sp
.Vb 3
\&    local uri = assert(URI:new("ftp://host/path"))
\&    uri:ftp_typecode("a")   \-\- ftp://host/path;type=a
\&    uri:ftp_typecode(nil)   \-\- ftp://host/path
.Ve
.Sp
Passing in an empty string has the same effect as nil, removing the parameter.
An empty type parameter will be returned as nil, the same as if the parameter
was missing.
.SH "References"
.IX Header "References"
This class is based on \*(L"\s-1RFC 1738\s0 section 3.2\*(R".  Unfortunately there isn't
currently an \s-1RFC\s0 for \s-1FTP\s0 URIs based on the more up to date \*(L"\s-1RFC 3986\*(R"\s0.
