@@ end

POD syntax

# pod syntax

=head1 NAME

Example #1

=cut

=head1 NAME

Example #2

=cut

# pod-ish syntax

=name

INHERITS

This package inherits behaviors from:

Venus::Path

METHODS

This package provides the following methods:

count

count(hashref $criteria) (number)

The count method uses the criteria provided to "search" for and return the number of blocks found.

Since 0.01

count example 1
# given: synopsis;

my $count = $data->docs->count;

# 6
count example 2
# given: synopsis;

my $count = $data->text->count;

# 3

data

data() (string)

The data method returns the text between the DATA and END sections of a Perl package or file.

Since 0.01

data example 1
# given: synopsis;

$data = $data->data;

# ...

docs

docs() (Venus::Data)

The docs method configures the instance for parsing POD blocks.

Since 0.01

docs example 1
# given: synopsis;

my $docs = $data->docs;

# bless({ etag => "=cut", from => "read", stag => "=", ... }, "Venus::Data")

find

find(maybe[string] $list, maybe[string] $name) (arrayref)

The find method is a wrapper around "search" as shorthand for searching by list and name.

Since 0.01

find example 1
# given: synopsis;

my $find = $data->docs->find(undef, 'name');

# [
#   { data => ["Example #1"], index => 4, list => undef, name => "name" },
#   { data => ["Example #2"], index => 5, list => undef, name => "name" },
# ]
find example 2
# given: synopsis;

my $find = $data->docs->find('head1', 'NAME');

# [
#   { data => ["Example #1"], index => 1, list => "head1", name => "NAME" },
#   { data => ["Example #2"], index => 2, list => "head1", name => "NAME" },
# ]
find example 3
# given: synopsis;

my $find = $data->text->find(undef, 'name');

# [
#   { data => ["Example Name"], index => 1, list => undef, name => "name" },
# ]
find example 4
# given: synopsis;

my $find = $data->text->find('titles', '#1');

# [
#   { data => ["Example Title #1"], index => 2, list => "titles", name => "#1" },
# ]

The search method returns the set of blocks matching the criteria provided. This method can return a list of values in list-context.

search example 1
# given: synopsis;

my $search = $data->docs->search({list => undef, name => 'name'});

# [
#   { data => ["Example #1"], index => 4, list => undef, name => "name" },
#   { data => ["Example #2"], index => 5, list => undef, name => "name" },
# ]
search example 2
# given: synopsis;

my $search = $data->docs->search({list => 'head1', name => 'NAME'});

# [
#   { data => ["Example #1"], index => 1, list => "head1", name => "NAME" },
#   { data => ["Example #2"], index => 2, list => "head1", name => "NAME" },
# ]
search example 3
# given: synopsis;

my $find = $data->text->search({list => undef, name => 'name'});

# [
#   { data => ["Example Name"], index => 1, list => undef, name => "name" },
# ]
search example 4
# given: synopsis;

my $search = $data->text->search({list => 'titles', name => '#1'});

# [
#   { data => ["Example Title #1"], index => 2, list => "titles", name => "#1" },
# ]

string

string(maybe[string] $list, maybe[string] $name) (string)

The string method is a wrapper around "find" as shorthand for searching by list and name, returning only the strings found.

string example 1
# given: synopsis;

my $string = $data->docs->string(undef, 'name');

# "Example #1\nExample #2"
string example 2
# given: synopsis;

my $string = $data->docs->string('head1', 'NAME');

# "Example #1\nExample #2"
string example 3
# given: synopsis;
