If you'd like to start implementing best practices, for yourself or your team, then Perl::Critic is the best place to start. The module is based on the Perl Best Practices book by Damien Conway and does a fairly good job implementing the suggestions made therein.
Note: I should mention (and Conwa...
Install DateTime on your PC and then use it in perl script:
use DateTime;
Create new current datetime
$dt = DateTime->now( time_zone => 'Asia/Ho_Chi_Minh');
Then you can access elements's values of date and time:
$year = $dt->year;
$month = $dt->month;
$day = $dt->day;
$...
Set single element:
$dt->set( year => 2016 );
Set many elements:
$dt->set( year => 2016, 'month' => 8);
Add duration to datetime
$dt->add( hour => 1, month => 2)
Datetime subtraction:
my $dt1 = DateTime->new(
year => 2016,
month => 8,
...
perl -Mojo -E 'p("http://localhost:3000" => form => {Input_Type => "XML", Input_File => {file => "d:/xml/test.xml"}})'
File d:/xml/test.xml will be uploaded to server which listen connections on localhost:3000 (Source)
In this example:
-Mmodule execu...

Modal dialog components can be instantiated via jQuery with the function $('#myModal').modal(options), where $('#myModal') is a top-level reference to the specific modal dialog and options is a Javascript object specifying the modal dialog's default attributes.
The options object allows for multipl...
Depending on the version of Weka being used different methods for loading ARFF files should be utilised.
Weka <3.5.5
The following sample code shows how to load an ARFF file:
import weka.core.Instances;
import java.io.BufferedReader;
import java.io.FileReader;
...
BufferedReader reader = n...
Many databases can be used in Weka. Firstly, the DatabaseUtils.props file must be edited to match your database; specifically you must provide your database's name, location, port and correct driver.
jdbcDriver=org.gjt.mm.mysql.Driver
jdbcURL=jdbc:mysql://localhost:3306/my_database
Then the dat...
IronPython enables to use generic classes and methods from the .net framework.
Generics can be used with the same syntax as accessing an index. For passing more than one type-parameter, they must be separated with a comma:
l = Dictionary[int, str]()
That way we create a dictionary where keys on...
A literal inside a enumeration is a discrete type so we can use attribute Image to find out which literal it is as text form. Notice that this prints out the same word as in the code (but in upper case).
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
type Fruit is (Banana, Pear, Orang...
Instead of attribute Image and Ada.Text_IO.Put on enumeration literals we can only use the generic package Ada.Text_IO.Enumeration_IO to print out the literals.
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
type Fruit is (Banana, Pear, Orange, Melon);
package Fruit_IO is new Enume...
You can set the desired UI widget's stylesheet using any valid CSS. The example below will set a QLabel's text color a border around it.
#include "mainwindow.h"
#include "ui_mainwindow.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::Mai...
Simply specifying a file destination, echo will create, write, or append to a file.
<echo file=example.txt" append="false">
hello world
</echo>
To print the contents of a file, we can use loadfile to read a file into a local property, and then use echo to print the value of it.
<loadfile property="contents" srcFile="example.txt" />
<echo message="${contents}" />
