Display and edit keyboard macros with GExperts – twm’s blog

Posted by jpluimers on 2017/03/13

Yes!

The GExperts Macro Library expert can now display and edit keyboard macros that have been recorded in the Delphi IDE.

Thomas did some great work on GExperts. Again.

Using Delphi nextgen compilers … https://xkcd.com/303/ some arguments to have both for the Win32 platform

Posted by jpluimers on 2017/03/08

Last week there was a nice poke by Stefan Glienke around the Delphi nextgen compiler being used for the upcoming Intel x64 Linux support in Delphi (yes, no Arm there, hopefully somewhere in the future) at [Archive.isUsing Delphi nextgen compilers … https://xkcd.com/303/

It resulted into a nice thread of strengths and weaknesses of the classic and nextgen compilers.

I’m emphasising a long term wish for the Win32 platform to have two compilers: a classic one and an LLVM nextgen one.

Reasons include this:

  • Various compiler architectures can emit code for the same end-platformm: Kylix Linux x86 support uses the classic compiler, new Linux x64 support is using the LLVM nextgen compiler
  • Debugging non-Win32 (x86 on Windows) is slow and buggy at best
  • LLVM nextgen compiler takes about 2 orders of magnitude longer than the classic compiler
  • the classic compiler has various optimisation deficits for about 2 decades and won’t be fixed
  • the LLVM nextgen compiler has many more optimisation opportunities than the classic compiler
  • the LLVM nextgen compiler supports zerobased strings and ARC which are almost impossible to debug because of the debugger issues so writing truly cross platform code using Delphi is a drag

So, please please please Delphi team: provide an LLVM nextgen compiler for the Win32 platform.

Delphi sorcery: Generics, modules and typeinfo

Posted by jpluimers on 2017/02/23

the release of 1.2 is almost there! We are working hard to deliver it shortly after the next Delphi release which will happen … soonish, I think. ;)

The release/1.2 branch has been around for a while – please take a look if you haven’t already. It contains a lot of new features and bugfixes. I will tell you more about some of the amazing features next time which won’t take as long as it took since the last blog post – promise. :)

Apart from a very interesting take on DI resolvers, the above great info too!

Please take a look at spring4d/branch/release/1.2 as it has been very stable for quite some time.

Delphi, resource files and includes – some links

Some links that were useful getting back into using Delphi with resource scripts and include files:

Maybe I should have considered this alternative:

Delphi and stuff: The strange limitation of 64 threads

Posted by jpluimers on 2017/02/21

… there’s no need to use WaitForMultipleObjects in Step 2. It’s fairly easy to keep a counter of active threads in the pool (interlocked-incremented when a thread starts, interlocked-decremented when a thread is finished). When the counter reaches zero (no more active threads), signal an event. With only one event to wait for, you can use WaitForSingleObject

So no more 64-thread (MAXIMUM_WAIT_OBJECTS) limits for pools…

Does anyone have a run-time fix for CreateInOutError raising an EInOutError with Code=3 (correct) and Message='Invalid file name - %s' (incorrect because System.SysUtils should have used System.SysConst not System.RTLConst and System.RTLConst wrongly duplicates some resource strings in System.SysConst) See [WayBack] http://qc.embarcadero.com/wc/qcmain.aspx?d=129530.
It would be so cool if a fix fills in the %s with the invalid file name.

Now that Delphi will reintroduce Linux as a target: what features / support do you expect in the compiler and libraries?

Posted by jpluimers on 2017/02/17

Almost 2 decades after the first Delphi Linux support in [WayBackBorland Kylix by an full tool-chain (IDE, compiler, debugger, libraries) running on Linux, Embarcadero/Idera is about to support Linux again in a cross-compiler fashion that was originally scheduled for late 2016 as Delphi Godzilla [WayBackEmbarcadero RAD Studio 2016 Product Approach and Roadmap – Embarcadero Community and [WayBackLinux support for Delphi to be available end of 2016 – Synopse.

It seems to be finally getting here as Delphi 10.2 Tokyo when you look at the [Archive.is] Delphi Linux Boot Camp promotion for instance at [WayBackDelphi Linux Boot Camp – Community Blogs – Embarcadero Community.

I’m curious at what people expect from it.

So please comment your expectations, for instance:

  • what Linux distribution targets
  • what processor architectures
  • what language support (ARC, classic, 1-based strings, etc)
  • what library support
  • what IDE support (like debugger features)
  • what speeds
