VoteField provides a vote field to your archetypes contents.

How does it work ?

From the view of the content, any user can vote for it by clicking on a button.

It also show the number of votes for the content.

Users can only vote once for a content. The vote verification is done with cookie.

From the edit page, owner can reset the counter with a checkbox.

See the examples in the folder to see how to add the field to your archetype content.

Plone is an open-source content management system built on top of the Zope application server. Plone is free software and is designed to be extensible. It is suited for an internal website or may be used as a server on the Internet, playing such roles as a document publishing system and groupware collaboration tool.

Sort::Fields is a Perl module that can sort lines containing delimited fields.

SYNOPSIS

use Sort::Fields;
@sorted = fieldsort [3, 2n], @lines;
@sorted = fieldsort +, [-1, -3, 0], @lines;

$sort_3_2n = make_fieldsort [3, 2n], @lines;
@sorted = $sort_3_2n->(@lines);

Sort::Fields provides a general purpose technique for efficiently sorting lists of lines that contain data separated into fields.

Sort::Fields automatically imports two subroutines, fieldsort and make_fieldsort, and two variants, stable_fieldsort and make_stable_fieldsort. make_fieldsort generates a sorting subroutine and returns a reference to it. fieldsort is a wrapper for the make_fieldsort subroutine.

The first argument to make_fieldsort is a delimiter string, which is used as a regular expression argument for a split operator. The delimiter string is optional. If it is not supplied, make_fieldsort splits each line using /s+/.

The second argument is an array reference containing one or more field specifiers. The specifiers indicate what fields in the strings will be used to sort the data. The specifier "1" indicates the first field, "2" indicates the second, and so on. A negative specifier like "-2" means to sort on the second field in reverse (descending) order. To indicate a numeric rather than alphabetic comparison, append "n" to the specifier. A specifier of "0" means the entire string ("-0" means the entire string, in reverse order).

The order in which the specifiers appear is the order in which they will be used to sort the data. The primary key is first, the secondary key is second, and so on.
fieldsort [1, 2], @data is roughly equivalent to make_fieldsort([1, 2])->(@data). Avoid calling fieldsort repeatedly with the same sort specifiers. If you need to use a particular sort more than once, it is more efficient to call make_fieldsort once and reuse the subroutine it returns.

stable_fieldsort and make_stable_fieldsort are like their "unstable" counterparts, except that the items that compare the same are maintained in their original order.

fields::aliased is a Perl module that can create aliases for object fields.

SYNOPSIS

package MyPackage;
use strict;
use fields qw($scalar @array %hash);

sub new {
my $class = shift;
my $self = fields::new($class);

return $self;
}

sub mymethod {
my MyPackage $self = shift;
use fields::aliased qw($self $scalar @array %hash);

$scalar = 1;
@array = (2 .. 4);
%hash = (one => 1, two => 2);
}

This module is a companion to the fields module, which allows efficient handling of instance variables with checking at compile time. It goes one step further and actually creates lexical aliases to the instance values, which can make code not only easier to type, but easier to read as well.

Declarations

You declare the fields using the fields pragma, as always.

use fields qw($scalar @array %hash nosigil);

Each field name may be preceded by a type sigil to indicate which kind of variable it is. Names without the type sigil are treated as scalars.

For names beginning with an underscore, see "PRIVATE FIELDS" below.

Constructors

You call fields::new to create the object.

my $self = fields::new($class);

Usage

In each method that uses the individual fields, you add a line similar to the following:

use fields::aliased qw($self $scalar @array %hash nosigil);

That is, list the variable being used for the object reference, and then the names of the fields that you are going to use in this method. fields::aliased takes care of declaring the appropriate Perl lexical variables and linking them to the appropriate field. You only need to specify the fields you are actually going to use, including any inherited from superclasses.

Mail::Message::Field contains one line of a message header.

INHERITANCE

Mail::Message::Field
is a Mail::Reporter

Mail::Message::Field is extended by
Mail::Message::Field::Fast
Mail::Message::Field::Flex
Mail::Message::Field::Full

SYNOPSIS

my $field = Mail::Message::Field->new(From => fish@tux.aq);
print $field->name;
print $field->body;
print $field->comment;
print $field->content; # body & comment
$field->print(*OUT);
print $field->string;
print "$fieldn";
print $field->attribute(charset) || us-ascii;

This implementation follows the guidelines of rfc2822 as close as possible, and may there produce a different output than implementations based on the obsolete rfc822. However, the old output will still be accepted.

These objects each store one header line, and facilitates access routines to the information hidden in it. Also, you may want to have a look at the added methods of a message:

my @from = $message->from;
my $sender = $message->sender;
my $subject = $message->subject;
my $msgid = $message->messageId;

my @to = $message->to;
my @cc = $message->cc;
my @bcc = $message->bcc;
my @dest = $message->destinations;

my $other = $message->get(Reply-To);

Validate_fields Class is an easy-to-use form field validation PHP script. This class can be used to validate database inputs or mail forms.
It can validate simple text, numbers, dates, urls, email addresses, and the presence of HTML tags. Invalid form fields will be reported inside a detailed error message.
Enhancements:
- A small improvement in the create_msg() method makes it possible to switch between the XHTML version and the simple HTML version.
- In the fields array one key was named "name", and it has been renamed to "value" to make it more clear.
- The variable declarations at the beginning of the validation method was removed.
- Because the value of a checkbox (radio) type field is only available if the element is checked, there are new functions to validate this elements.

UnHide fields provides this extension allow you to view and edit hidden fields content.

In computer science, data that has several parts can be divided into fields. For example, a computer may represent todays date as three distinct fields: the day, the month and the year.

Programming languages usually have a record data type to represent composite data types as a series of fields. An array of boolean values can be represented as a bit field.

Max Fighter is a vertical-scrolling asteroids shootemup game.

You have a bad feeling about this: For only one brief moment you let your attention slip, and suddenly, you find your spaceship heading right into a vast asteroid field. Though it does not seem very dense at the outskirts, your board computer readouts make you doubt you will ever see the other side of it - and did your radar just pick up traces of pirate activity!?

Keep control of your spaceship as you go ever deeper into the asteroid field and the gameplay reaches breakneck speed. Shoot asteroids and containers and collect power-ups, shield energy and special weapons. And last but not least - beware of the pirates!

VFGEN is a Vector Field File Generator for differential equation solvers and other computational tools.
There are many excellent programs available for solving differential equations and computing bifurcations of vector fields. However, each has its own format for specifying the vector field that defines the differential equation. VFGEN lets you define your vector field once (using XML), and export the vector field in several formats. VFGEN uses a C++ symbolic algebra library (GiNaC) to generate Jacobians and higher derivatives automatically.
Main features:
- Specify your equations once, and export to multiple file formats.
- Generate analytical expressions for Jacobians and higher derivatives automatically.
- Available export formats include MATLAB, Scilab, AUTO, GNU Scientific Library (GSL), SciPy, PyDSTool, XPP and more.
- New in Version 2.1.0: Octave, PyDSTool and RADAU5 commands added.
- New in Version 2.0.0: VFGEN can generate code for delay equations.
