NAME

Net::Evernote::Simple - Simple interface to the Evernote API

SYNOPSIS

use Net::Evernote::Simple;

my $evernote = Net::Evernote::Simple->new(
      # Obtain a developer token from Evernote and put it here
    dev_token => "XXX",
);

  # check if our client API version still works
if( ! $evernote->version_check() ) {
    print "Evernote API version out of date!\n";
}

my $note_store = $evernote->note_store();

if( !$note_store ) {
    die "getting notestore failed: $@";
}

  # retrieve all of our notebooks
my $notebooks =
  $note_store->listNotebooks( $evernote->dev_token() );

for my $notebook ( @$notebooks ) {
   print $notebook->name(), "\n";
}

DESCRIPTION

Net::Evernote::Simple enables easy access to the Evernote API with developer tokens.

Developer tokens allow read/write access to a user's Evernote data. If you don't have a developer token yet, you can obtain one here:

http://dev.evernote.com/documentation/cloud/chapters/Authentication.php#devtoken

Net::Evernote::Simple then lets you obtain a note_store object which can then be used with a variety of functions of the Evernote API described here:

http://dev.evernote.com/documentation/cloud/chapters/

METHODS

new()

Constructor, creates a helper object to retrieve a note store object later. To access Evernote data, you need a developer token and specify it either with the dev_token parameter in the constructor call:

my $evernote = Net::Evernote::Simple->new(
    dev_token => "XXX",
);

You can omit the dev_token parameter and let Net::Evernote::Simple search for a configuration file named ~/.evernote.yml containing the developer token like

dev_token: XXX

within the YAML data. To specify an alternative YAML file, use

my $evernote = Net::Evernote::Simple->new(
    config_file => "/path/to/evernote.yml",
);

The object points to the Evernote production server by default. If you want to use the sandbox instead, use

my $evernote = Net::Evernote::Simple->new(
    evernote_host => "sandbox.evernote.com",
);

version_check()

Contact the Evernote API server and verify if the client API version we're using is still supported. If this fails, please contact the author of this module and ask to update the distribution on CPAN.

To make things easier for users of this module, the Evernote

dev_token()

Return the value of the developer token. Many Evernote API functions need the value of the token (like listNotebooks() or createNote()).

note_store()

Obtain a note_store object from Evernote SDK, which allows you call all sorts of Evernote data manipulation functions, like listNotebooks() or createNote().

One thing to keep in mind when using this library is that the original EDAMxxx namespace of the Evernote API has been converted to Net::Evernote::Simple::EDAMxxx to avoid collisions.

To obtain the fully qualified module names, you can use the special sdk() method, so instead of saying

my $filter =
  Net::Evernote::Simple::EDAMNoteStore::NoteFilter->new();

you can just as well say

my $filter = $en->sdk( "EDAMNoteStore::NoteFilter" )->new();

See the example below to get an idea on how to use this API. Consult the official Evernote API documentation at the link listed above for details on data structures used and parameters needed.

EXAMPLE: Finding and printing notes

use Net::Evernote::Simple;
my $en = Net::Evernote::Simple->new();

if( ! $en->version_check() ) {
  die "Evernote API version out of date!";
}

my $note_store = $en->note_store() or
   die "getting notestore failed: $@";

my $filter = $en->sdk(
  "EDAMNoteStore::NoteFilter" )->new(
    { words => "foo bar baz" } );

my $offset    = 0;
my $max_notes = 100;

my $result = $note_store->findNotes(
    $en->{ dev_token },
    $filter,
    $offset,
    $max_notes
);

for my $hit ( @{ $result->{ notes } } ) {
  my $note = $note_store->getNote( 
   $en->{ dev_token }, $hit->{ guid }, 1 );
  print $note->{ content };
}

EXAMPLE: Add a note with a JPG image to notebook "Recipes"

use Net::Evernote::Simple;
use Sysadm::Install qw( slurp );
use Digest::MD5 qw( md5_hex );

my( $jpg_file ) = @ARGV;

if( !defined $jpg_file ) {
    die "usage: $0 jpg_file";
}

my $evernote = Net::Evernote::Simple->new(
  # Obtain a developer token from Evernote and put it here
  # or use a ~/.evernote.yml file with a "dev_token" entry
    # dev_token => "XXX",
);

  # check if our client API version still works
if( ! $evernote->version_check() ) {
    die "Evernote API version out of date!";
}

my $note_store = $evernote->note_store();

if( !$note_store ) {
   die "getting notestore failed: $@";
}

  # retrieve all of our notebooks
my $notebooks =
   $note_store->listNotebooks( $evernote->dev_token() );

my $notebook_guid;

  # see if we can find one named "Recipes"
for my $notebook ( @$notebooks ) {
    if( $notebook->name() eq "Recipes" ) {
        $notebook_guid = $notebook->guid();
        last;
    }
}

if( !defined $notebook_guid ) {
    die "Notebook 'Recipes' not found";
}

my $data = Net::Evernote::Simple::EDAMTypes::Data->new();

my $content = slurp $jpg_file;
$data->body( $content );
my $hash = md5_hex( $content );
$data->bodyHash( $hash );
$data->size( length $content );

my $r = Net::Evernote::Simple::EDAMTypes::Resource->new();
$r->data( $data );
$r->mime( "image/jpeg" );
$r->noteGuid( "" );

my $note = Net::Evernote::Simple::EDAMTypes::Note->new();
$note->title( "Our note title" );
$note->resources( [$r] );
$note->notebookGuid( $notebook_guid );

my $enml = <<EOT;
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE en-note SYSTEM "http://xml.evernote.com/pub/enml2.dtd">
<en-note>
   <en-media type="image/jpeg" hash="$hash"/>
</en-note>
EOT

$note->content( $enml );

$note_store->createNote(
   $evernote->dev_token(), $note );
