.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Provides functions to parse and compose \s-1URI\s0
strings.  The following functions are provided:
.ie n .IP "($scheme, $auth, $path, $query, $frag) = uri_split($uri)" 4
.el .IP "($scheme, \f(CW$auth\fR, \f(CW$path\fR, \f(CW$query\fR, \f(CW$frag\fR) = uri_split($uri)" 4
.IX Item "($scheme, $auth, $path, $query, $frag) = uri_split($uri)"
Breaks up a \s-1URI\s0 string into its component
parts.  An \f(CW\*(C`undef\*(C'\fR value is returned for those parts that are not
present.  The \f(CW$path\fR part is always present (but can be the empty
string) and is thus never returned as \f(CW\*(C`undef\*(C'\fR.
.Sp
No sensible value is returned if this function is called in a scalar
context.
.ie n .IP "$uri = uri_join($scheme, $auth, $path, $query, $frag)" 4
.el .IP "\f(CW$uri\fR = uri_join($scheme, \f(CW$auth\fR, \f(CW$path\fR, \f(CW$query\fR, \f(CW$frag\fR)" 4
.IX Item "$uri = uri_join($scheme, $auth, $path, $query, $frag)"
Puts together a \s-1URI\s0 string from its parts.
Missing parts are signaled by passing \f(CW\*(C`undef\*(C'\fR for the corresponding
argument.
.Sp
Minimal escaping is applied to parts that contain reserved chars
that would confuse a parser.  For instance, any occurrence of '?' or '#'
in \f(CW$path\fR is always escaped, as it would otherwise be parsed back
as a query or fragment.
