I wish the Delphi language supported multi-line strings

Posted by jpluimers on 2018/06/21

Very often, I see people ask for how to embed multi-line strings in a Delphi source file.

The short answer is: you can’t.

The long answer is: you can’t and if you want you have to hack your way around.

The answer should be: just like any of these languages that do support multiline strings:

Many languages support this through a feature called HEREDOC.

Now in Delphi and other languages like Java are building ugly workarounds like for instance this one: [WayBackRAD Studio Tip: Using resource scripts to organize project dependencies. – Chapman World.

The 68 things the CLR does before executing a single line of your code (*) · Performance is a Feature!

Posted by jpluimers on 2018/04/16

Because the CLR is a managed environment there are several components within the runtime that need to be initialised before any of your code can be executed. This post will take a look at the EE (Execution Engine) start-up routine and examine the initialisation process in detail.

Lots of interesting stuff happening before your code even gets executed. Many of the pieces can log.

C# 8.0 features – an exiting list of new possibilities on the horizon

Posted by jpluimers on 2018/04/04

Shamelessly adapted from [WayBack] C# 8.0 features Extension everything — a new syntax for extension methods that will also allow extension “other things,” like the much-anticipated exte… – Lars Fosdal – Google+, including the original posts where the topics were covered:

C# 8.0 features

Post 1

[WayBack] C# 8.0 Features: A Glimpse of the Future – NDepend: C# 8.0 is on the horizon and will be here before you know it, bringing with it some interesting functionality. Let’s take a peek into the future.

Extension everything — a new syntax for extension methods that will also allow extension “other things,” like the much-anticipated extension properties.

Default implementations on interfaces — this allows you to implement methods on interfaces, giving them a default implementation. That will enable you to add new methods to interfaces without breaking its clients.

Nullable reference types — probably one of the most anticipated features ever. It’s a reinterpretation (a “retcon” for you comic book geeks out there) of all the reference types as nullable and the introduction of a new syntax to denote nullable types, accompanied by several types of static checks, to prevent several classes of errors regarding these types. Say farewell to the null reference exception!

[WayBack] C# 8.0 Features: Another Glimpse of the Future – NDepend This post covers two probable C# 8.0 features: null coalescing assignment and records. It explains what they are and reports on their current statuses, as well.

Null coalescing assignment — a very simple feature to shorten the check for null before assigning to a variable.

Records — this one is pretty interesting. It’s basically a very short way for you to declare classes that are only data holders. The compiler gives you Equals and GetHashCode implementations, a constructor, properties, and immutability for free, allowing you to do something more interesting with your life than writing loads of boilerplate code.

[WayBack] C# 8.0 Features: A Final Glimpse Of The Future – NDepend: Here’s our final post in our C# 8.0 series, where we glimpse into the future. Today we’ll cover another two possible features: target-typed new expressions and covariant return types.

Target-typed “new” expressions — a way for you to omit the type from a constructor call, making the code simpler and less redundant.

Covariant return types — a much-anticipated feature that allows an overriding method to return a more derived type than the original type from the base class.

I really hope they publish the full specs soon, but given that the C# 7 specs yet have to (see [WayBack] C Sharp (programming language) – Wikipedia: Versions), I do not hold my breath, even though it had lots of interesting new stuff too:
