SYNOPSIS

13         package Your::Pkg;
14         use Mixin::Linewise::Readers -readers;
15
16         sub read_handle {
17           my ($self, $handle) = @_;
18
19           LINE: while (my $line = $handle->getline) {
20             next LINE if $line =~ /^#/;
21
22             print "non-comment: $line";
23           }
24         }
25
26       Then:
27
28         use Your::Pkg;
29
30         Your::Pkg->read_file($filename);
31
32         Your::Pkg->read_string($string);
33
34         Your::Pkg->read_handle($fh);
35

EXPORTS

37       "read_file" and "read_string" are exported by default.  Either can be
38       requested individually, or renamed.  They are generated by
39       Sub::Exporter, so consult its documentation for more information.
40
41       Both can be generated with the option "method" which requests that a
42       method other than "read_handle" is called with the created IO::Handle.
43
44       If given a "binmode" option, any "read_file" type functions will use
45       that as an IO layer, otherwise, the default is "utf8_strict".
46
47         use Mixin::Linewise::Readers -readers => { binmode => "raw" };
48         use Mixin::Linewise::Readers -readers => { binmode => "encoding(iso-8859-1)" };
49
50   read_file
51         Your::Pkg->read_file($filename);
52         Your::Pkg->read_file(\%options, $filename);
53
54       If generated, the "read_file" export attempts to open the named file
55       for reading, and then calls "read_handle" on the opened handle.
56
57       An optional hash reference may be passed before $filename with options.
58       The only valid option currently is "binmode", which overrides any
59       default set from "use" or the built-in "utf8_strict".
60
61       Any arguments after $filename are passed along after to "read_handle".
62
63   read_string
64         Your::Pkg->read_string($string);
65         Your::Pkg->read_string(\%option, $string);
66
67       If generated, the "read_string" creates a handle on the given string,
68       and then calls "read_handle" on the opened handle.  Because handles on
69       strings must be octet-oriented, the string must contain octets.  It
70       will be opened in the default binmode established by importing.  (See
71       "EXPORTS", above.)
72
73       Any arguments after $string are passed along after to "read_handle".
74
75       Like "read_file", this method can take a leading hashref with one valid
76       argument: "binmode".
