It took me a while to figure this one out:
When you have a registered Delphi, you can Ctrl-Click browse both the units and symbols of RTL, VCL, etc. But Delphi will not recompile these units.
Some third party components you cannot Ctrl-Click browse the units or symbols, unless you put the source directory in the Delphi Library Path (which causes them to be compiled each and every time).
This is because:
- the precompiled DCUs are in the Delphi Library Path.
- the source code is added to the Delphi Browsing Path (and sometimes not even that).
- the DCUs don’t contain information that the source code is Browsable or Referencable as it was compiled with {$Y-}.
These are the possible values for that directive:
- {$Y-} or {$DEFINITIONINFO OFF} or {$REFERENCEINFO OFF},
- {$Y+} or{$REFERENCEINFO ON},
- {$YD} or {DEFINITIONINFO ON}
So please component vendors: when you ship source code, make it IDE-browsable as well by compiling with $YD or $Y+.

Stefan Glienke started some interesting demographics polls on the G+ Delphi community.
Demographics are about group members that actually voted. Which might rule out Delphi programmers not writing English well.
Despite that, I think it actually tells a lot, especially when you read the comments as well.
And it made DavidI provide some background on the geographic distribution: Where in the world are programmers using Delphi? – Blogs.

Especially when using Delphi 2007 on Windows x64 system (8.x, 7, Vista, 2012 Server, 2008 Server, …), the Delphi specific .Targets files used by msbuild are simply installed to the wrong location.
A better warning for this is in my BeSharp.net repository: Run-Dependend-rsvars-From-Path.bat thanks to David Millington who wrote this:
If you copy
- Borland.Common.Targets
- Borland.Cpp.Targets
- Borland.Delphi.Targets
- Borland.Group.Targets
from
- %windir%\Microsoft.NET\Framework\v2.0.50727
to
- %windir%\Microsoft.NET\Framework64\v2.0.50727
then building via the command line works.
The rsvars.bat file is correct.
Note that my batch file checks for all target file sets:
Delphi 2007:
set requiredTargets=Borland.Common.Targets Borland.Cpp.Targets Borland.Delphi.Targets Borland.Group.Targets
Delphi 2009 and up:
set requiredTargets=CodeGear.Common.Targets CodeGear.Cpp.Targets CodeGear.Delphi.Targets CodeGear.Deployment.Targets CodeGear.Group.Targets CodeGear.Idl.Targets CodeGear.Profiles.Targets
if %bdsVersion%==8 set requiredTargets=CodeGear.Common.Targets CodeGear.Cpp.Targets CodeGear.Delphi.Targets CodeGear.Group.Targets CodeGear.Idl.Targets
if %bdsVersion%==13 set requiredTargets=CodeGear.Common.Targets CodeGear.Cpp.Targets CodeGear.Delphi.Targets CodeGear.Deployment.Targets CodeGear.Group.Targets CodeGear.Profiles.Targets

A few people asked, so below is a picture of just a piece of my books closet.
From left to right:
- Object Professional 1.0 manuals volume 1-3
- BTree Filer 5.0 manual
- Turbo Professional manual (from 1985!)
- Borland Paradox Engine 3.0 manuals
- Crystal Reports Developers Edition
- Borland Open Architecture Handbook for Pascal
- Turbo Pascal 5.5 OOP Guide

- Programming with Turbo Vision
This is only the front-left portion of one shelve. Most shelves are two deep and about 4 times as wide as what you see here (:
I have floppies somewhere in my archive too. Need to dig them up some day.

A while ago I wrote about Delphi XE7 is out with version 21.0.17017.3725; Spring4D is almost ready, now I can repeat parts of it for XE8.
The download links for Delphi XE8, C++Builder XE8 and RAD Studio XE8 are there: ftpd and altd. A whopping 7,217,184,768 bytes (compare that to XE7 update 1 at 5,649,917,952 bytes: almost 30% increase) that has been seeded a few days ago with the version time stamped at the end of last month (like xe7), here is the version number: 22.0.19027.8951.
Before installing, note that in addition to the below documentation links:
Be sure to have at least 70 gigabytes of free disk space before you attempt to install.
This in addition to the almost 7 GiB ISO file (:
The download is fast as altd is on akamai: the 7 GiB downloaded in about 16 minutes. Google can do the math.
XE8 doc links
Spring4D
On the Spring4D side, Stefan and Honza have added XE8 support, so a new release of that can be near.

During any software life cycle, you will want to phase out some code, and most likely want to mark code to be phased out in the future.
So here are two examples on how to do that in C# and in Delphi that just shows the effects of obsoleting/deprecating code.

A lot of the stuff on the Embarcadero docwiki hurts. For instance most of the REST stuff (I’m not calling it documentation) is just generated scaffolding. Like REST.Json.TJson.
But the TRESTResponseDataSetAdapter has some amazing documenation. About TComponent that is:
TComponent is the common ancestor of all component classes.
TComponent is the base class for all components. Components are persistent objects that have the following capabilities:
IDE integration. The ability to appear on an IDE palette and be manipulated in a Form Designer.
Ownership. The ability to manage other components. If component A owns component B, then A is responsible for destroying B when A is destroyed.
Streaming and filing. Enhancements of the persistence features inherited from TPersistent.
…
To assist the doc team: this is a query for all pages containing “TComponent is the common ancestor of all component classes.”. Feel free to [WayBack] QC or QP it.
