Markus Joos started a nice G+ thread on anonymous method formatting which ended up into a discussion of functional programming and a peek into what Spring4D 1.3 can offer.
Note you might need to be part of the G+ Delphi Developers Community to read the thread.

This is the way a wiki should work:
Thanks Simon Stuart for asking, and many others (especially Johan) for providing the info.
Note the version that is missing (;

Normal people would give Valentine presents today.
But 20 years ago, Borland thought it was a nice idea to release Delphi. Then a revolutionary new tool and lots of scepticism. Now – after 20 years – still going strong, despite all kinds of funny things that management at Borland, InPrise, etc did and the wild ride the market had.
Happy birthday Delphi!

After a hectic week bringing back memories from a long time ago, I remembered the really early Delphi days.
Long before [WayBack] QC2747, back when it was still called AppBuilder, several people – including me – made the wish for an undo/redo functionality on the Delphi compuserve board.
Back then, the argument was that the designer needed to be restructured to do that. Now that it has – to accommodate FMX – and it is time, especially for the vast majority of Delphi users primarily using the designers to get work done.
So my wish, after 20+ years of Delphi use:
Please bring multi-level undo/redo functionality in the Delphi designer (form, datamodule, etc).

Interesting, I never knew that [WayBack] Process Monitor has had an API to send messages to, but it has had this ability for almost 5 years: [Archive.is] See the I/O You Caused by Getting Your Diagnostic Tracing into Process Monitor | Wintellect.
I did know about [WayBack] OutputDebugString and the DBWIN protocols, but this was new.
The ZIP file for Process Monitor is offline (but you can find it by searching for ProcMonDebugOutput.zip), and contains .h files and a .NET example.
Thanks [WayBack] Oliver Giesen for the [WayBack] Delphi translation!

Cool: this makes it way easier to do repeated Delphi installs for testing purposes:
Setup.exe /s LANGUAGE=English EN=TRUE DE=TRUE KEY1=XXXX KEY2=XXXXXX KEY3=XXXXXX KEY4=XXXX
There are many more parameters in Delphi sorcery: Unattended Delphi installation – how?, but the above is already a good start.
Thanks Stefan Glienke for having shared this!

Because of Delphi sorcery: New dynamic array type in Spring4D 1.2, I updated this article from 2009: Delphi operator overloading: table of operators, names, and some notes on usage and ‘glitches’.
When I wrote the original article in 2009 the in operator wasn’t documented to be overloadable.
It is overloadable, and newer documentation includes it: http://docwiki.embarcadero.com/RADStudio/en/Operator_Overloading_%28Delphi%29.
In addition I clarified a few things better (like not needing to return Boolean for comparison and set operators) and fixed a few typos and links.
The glitches are still there, so I’ve kept those.

This used to be a great Delphi-only feature that I missed in Visual Studio, but I found the downloadable free extension Favorite Documents extension.
It is a by Sergey Vlasov, who has a whole bunch of free and paid Visual Studio add-ins, extensions and tools.

One of the features that bites me over and over again is the ZEROBASEDSTRINGS that got introduced in Delphi XE3 and is by default ON in mobile compilers and OFF in Desktop compilers.
Back then, Mark Edington showed a small example of the effects:
| procedure ZeroBasedTest; | |
| const | |
| S: string = '012'; | |
| begin | |
| {$ZEROBASEDSTRINGS OFF} | |
| Writeln(S[1]); // shows "0" | |
| Writeln(S.Chars[1]); // shows "1" | |
| {$ZEROBASEDSTRINGS ON} | |
| Writeln(S[1]); // shows "1" | |
| Writeln(S.Chars[1]); // shows "1" | |
| end; |
and then explained:
The XE3 RTL source code has been refactored to be string index base agnostic. In most cases this is done by utilizing string helper functions which are always zero based.
When it is necessary to traverse a string, the Char[] property is often used to access the individual characters without concern for the current state of the compiler with respect to zero based strings.In addition, the “Low” and “High” standard functions can now be passed a string variable to provide further flexibility as needed.
When zero based strings are enabled, Low(string) will return 0, otherwise it will return 1. Likewise, High() returns a bounds adjusted length variation.
The problem is the non-existent forward compatibility of the other compilers (Delphi XE2 and lower).
So if you have library code that needs to work in Delphi versions, you cannot use the High and Low to make the code ZEROBASEDSTRINGS neutral.
Many Delphi developers regularly skip many Delphi versions, so these are still popular:
The result is that library code is full of conditionan IF/IFDEF blocks like these:
| {$ifdef GX_VER240_up} | |
| for Index := Low(input) to High(input) do // for ZEROBASEDSTRINGS | |
| {$else} | |
| for Index := 1 to Length(input) do | |
| {$endif GX_VER240_up} |
