.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
In the spirit of YAML::Tiny this is a lightweight, dependency-free
\&\s-1YAML\s0 reader. While \f(CW\*(C`YAML::Tiny\*(C'\fR is designed principally for working
with configuration files \f(CW\*(C`Data::YAML\*(C'\fR concentrates on the transparent
round-tripping of \s-1YAML\s0 serialized Perl data structures.
.PP
The syntax accepted by \f(CW\*(C`Data::YAML::Reader\*(C'\fR is a subset of \s-1YAML\s0.
Specifically it is the same subset of \s-1YAML\s0 that Data::YAML::Writer
produces. See Data::YAML for more information.
.SH "INTERFACE"
.IX Header "INTERFACE"
.ie n .IP """new""" 4
.el .IP "\f(CWnew\fR" 4
.IX Item "new"
Creates and returns an empty \f(CW\*(C`Data::YAML::Reader\*(C'\fR object. No options may be passed.
.ie n .IP """read( $source )""" 4
.el .IP "\f(CWread( $source )\fR" 4
.IX Item "read( $source )"
Read \s-1YAML\s0 and return the data structure it represents. The \s-1YAML\s0 data may be supplied by a
.RS 4
.IP "\(bu" 4
scalar string containing \s-1YAML\s0 source
.IP "\(bu" 4
the handle of an open file
.IP "\(bu" 4
a reference to an array of lines
.IP "\(bu" 4
a code reference
.RE
.RS 4
.Sp
In the case of a code reference a subroutine (most likely a closure)
that returns successive lines of \s-1YAML\s0 must be supplied. Lines should
have no trailing newline. When the \s-1YAML\s0 is exhausted the subroutine must
return undef.
.Sp
Returns the data structure (specifically either a scalar, hash ref or
array ref) that results from decoding the \s-1YAML\s0.
.RE
.ie n .IP """get_raw""" 4
.el .IP "\f(CWget_raw\fR" 4
.IX Item "get_raw"
Return the raw \s-1YAML\s0 source from the most recent \f(CW\*(C`read\*(C'\fR.
.SH "BUGS AND LIMITATIONS"
.IX Header "BUGS AND LIMITATIONS"
No bugs have been reported.
.PP
Please report any bugs or feature requests to
