Is there a keyboard shortcut to go to the next/previous compiler error in the current …

Posted by jpluimers on 2020/02/11

Via: [WayBack] Is there a keyboard shortcut to go to the next compiler error in the current source file? – Jeroen Wiert Pluimers – Google+:

Primož Gabrijelčič:
Alt-F7, Alt-F8 IIRC

And indeed, it is sort of documented as of Delphi 2007 for “Message View”, but appears to be a much older shortcut:

I also completely forgot the compiler output is indeed a “Message View”.

Why does HRESULT begin with H when it’s not a handle to anything? – The Old New Thing

Posted by jpluimers on 2020/02/06

Interesting bit of history: [WayBack] Why does HRESULT begin with H when it’s not a handle to anything? – The Old New Thing.

TL;DR:

  1. It used to be a handle
  2. Few programs cared about the underlying objects
  3. Managing the underlying objects was way too expensive
  4. It got trimmed down to a number, but the name stuck

Delphi Berlin and up without disabled Castalia: Use Ctrl+W to select content in the IDE code editor. Place your curso…

Posted by jpluimers on 2020/02/06

If you have enough guts to keep Castalia enabled and have Delphi Berlin or higher, then you can use this shortcut:

[WayBack] Tip: Use Ctrl+W to select content in the IDE code editor. Place your cursor some random piece of code, preferably deep in code that have nested block… – Lars Fosdal – Google+

The magic Delphi ReturnAddress intrinsic

Posted by jpluimers on 2020/02/05

I could not find any official place where ReturnAddress is documented even though it is used at quite a few places in the RTL, VCL, FMX and 3rd party libraries like DUnitX, Spring4D, JCL, ReportBuilder, TeeChart.

I tried searching it in the contexts of Delphi 2007, Delphi 2009, but there is only a [Archive.is] different System.ObjAuto.TParameters.ReturnAddress documented in XE2 and higher.

procedure Abort;
begin
  raise EAbort.CreateRes(@SOperationAborted) at ReturnAddress;
end;

There is a (usually broken*) ReturnAddr function used in various places of the RTL/VCL/FMX and (therefore wrongfully copied) in many other peoples code.

  function ReturnAddr: Pointer;
  // From classes.pas
  asm
    MOV     EAX,[EBP+4] // sysutils.pas says [EBP-4], but this works !
  end;
  • See the above link; I think this was fixed in Delphi XE, but the issue is still open.

Related to the above is the documented ExceptAddr.

I’ve used this in my ExceptionHelperUnit to build a GetStackTrace function in the example gist below.

I found these posts documenting the behaviour of the above intrinsic functions and more:

I love installers that can download and install in parallel threads….

Posted by jpluimers on 2020/02/04

[WayBack] I love installers that can download and install in parallel threads. Embarcadero and Zypper can learn from this. – Jeroen Wiert Pluimers – Google+

Most Linux distributions have package managers that can do this (apt and yum can), but OpenSuSE zypper (actually ZYpp) cannot even download packages in parallel:

Embarcadero is in the same state as zypper.

Sunsetting Mercurial support in Bitbucket – Bitbucket

Posted by jpluimers on 2020/01/30

February 1st, the start commences of Sunsetting Mercurial support in Bitbucket – Bitbucket [WayBack]. Starting June 1st, only git is supported by Bitbucket, despite them having started with and focused mainly Mercurial at first.

Here are the major dates of the sunset:

  • February 1, 2020: users will no longer be able to create new Mercurial repositories
  • June 1, 2020: users will not be able to use Mercurial features in Bitbucket or via its API and all Mercurial repositories will be removed.

All current Mercurial functionality in Bitbucket will be available through May 31, 2020.

So by now you should have started migrating from Mercurial to git, probably away from BitBucket.
