Current date and time can be found with getCurrentTime: import Data.Time print =<< getCurrentTime -- 2016-08-02 12:05:08.937169 UTC Alternatively, just the date is returned by fromGregorian: fromGregorian 1984 11 17 -- yields a Day

Given a Day, we can perform simple arithmetic and comparisons, such as adding: import Data.Time addDays 1 (fromGregorian 2000 1 1) -- 2000-01-02 addDays 1 (fromGregorian 2000 12 31) -- 2001-01-01 Subtract: addDays (-1) (fromGregorian 2000 1 1) -- 1999-12-31 addDays (-1) (fromGregorian...

[footag foo="value of 1" attribute-2="value of 2"] In wordpress admin we use pre defined shortcodes by writing the shortcode name inside square brackets and optionally adding attributes to it separating by space.

function footag_func( $atts ) { return "foo = {$atts['foo']}"; } add_shortcode( 'footag', 'footag_func' ); In plugins we can add shortcodes using the add_shortcode function. The shortcode can be used in any Wordpress page or post just by enclosing it in square brackets. [footag...

enum SomeEnum { A, B } let enumValues:Array<string>= []; for(let value in SomeEnum) { if(typeof SomeEnum[value] === 'number') { enumValues.push(value); } } enumValues.forEach(v=> console.log(v)) //A //B

The IsHighResolution property indicates whether the timer is based on a high-resolution performance counter or based on the DateTime class. This field is read-only. // Display the timer frequency and resolution. if (Stopwatch.IsHighResolution) { Console.WriteLine("Operations timed ...

This code requires that you use the PDFlib library for it to function properly. <?php $pdf = pdf_new(); //initialize new object pdf_begin_document($pdf); //create new blank PDF pdf_set_info($pdf, "Author", "John Doe"); //Set info about your PDF pdf_set_info($pd...

The register sp is used as stack pointer, pointing to the last stored value into stack ("top" of stack). So EX (sp),hl will exchange value of hl with the value on top of stack. Contrary to "top" word, the stack grows in memory by decreasing the sp, and releases ("pops"...

You can use a method annotated with @testSetup to write code that will have been executed before each test run: public class AccountService { public static Account fetchAccount() { return [ SELECT Id, Name FROM Account LIMIT 1 ]; } } @isTest public class AccountServiceTest { priv...

While you can use the @testSetup annotation to designate a method to be run before tests are executed, this method will usually only be run once. If you need code to be run before each test, you can use a static block: @isTest public class MyTest { static { // code here will be run before ...
