On the Delphi TCommandParser class for parsing command-lines and arguments (via: Suggestions for how to define command line parameters – Stack Overflow)

Posted by jpluimers on 2015/05/13

A while ago, I posted [WayBack] the below StackOverflow answer. Recently a friend asked me about command-line parsing in Delphi, so here is the re-run:

Delphi contains a really nice unit called CommandParser with a [WayBack] TCommandParser class that does commandline parsing for you. Since it has [WayBack] virtually no documentation, here are a few things to get started. It works even in Delphi 2007.

I have a HiddenExecutable example at our open source bo repository.

Basically you:

  • TComponent that contains the properties you want to expose as commandline parameters (that is THiddenExecuteSettings in the HiddenExecuteSettingsUnit
  • a commandline parser controller. In our case THiddenExecuteArguments in theTHiddenExecuteArgumentsUnit (in retrospect not such a good name) that contains an InitCommandLine method that sets up a TCommandParser instance passing it your TComponent
  • It then executes a couple of [WayBack] AddSwitch calls to setup the parameters with both abbreviated and full commandline switches (like h and help)
  • ProcessCommandLine method on the TCommandParser instance to process the commandline and fill the properties of your TComponent (in my example, this is done in the ProcessCommandLine method).

Now comes the fun:

  • TCommandParser has a HelpText method that fully automatically assembles a helptext based upon what you fed it with the AddSwitch methods.
  • TCommandParser also has a SaveOptions method that allows you to save the current settings of your TComponent into a settings file.

The Delphi units you need are these which you can get from the Embarcadero [WayBack] radstudiodemos.sourceforge.net demo repository:

CommandParser in '...\radstudiodemos.sourceforge.net\branches\RadStudio_XE2\Delphi\Database\dbExpress\Utils\CommandParser.pas',
PropertyHelpers in '...\radstudiodemos.sourceforge.net\branches\RadStudio_XE2\Delphi\Database\dbExpress\DbxDataPump\PropertyHelpers.pas',
ParseIds in '...\radstudiodemos.sourceforge.net\branches\RadStudio_XE2\Delphi\Database\dbExpress\DbxDataPump\ParseIds.pas',

Edit: [WayBack] John Kaster wrote a nice [WayBack] article on EDN that includes [WayBack] more details on using the TCommandParser.

Note the above mentioned code mostly is on [WayBack] https://bitbucket.org/jeroenp/wiert.me/src/tip/Native/Delphi/Apps/Console/HiddenExecuteConsoleProject

Since Delphi XE7, this unit does not ship with Delphi any more, but it is still at [WayBack] RAD Studio Demo Code / Code / [r2029] /branches/RadStudio_XE6/Object Pascal/Database/dbExpress/Utils/CommandParser.pas.

Delphi Component vendors: when you ship source code, make it IDE-browsable as well by compiling with $YD or $Y+

Posted by jpluimers on 2015/05/06

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:

  1. {$Y-} or {$DEFINITIONINFO OFF} or {$REFERENCEINFO OFF},
  2. {$Y+} or{$REFERENCEINFO ON},
  3. {$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+.

Interesting, Lars Fosdal writes:

I hope EMBT is paying attention.

Currently live at http://channel9.msdn.com/

I already liked the 7 minute C#6 video from last year. This is even better.

Some interesting demographics on the G+ Delphi Developers community

Posted by jpluimers on 2015/04/28

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.

Delphi on Windows x64: solution when project compiles fine under IDE, but not using MSBuild

Posted by jpluimers on 2015/04/21

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

Now that XE8 is out, some Turbo Pascal history

Posted by jpluimers on 2015/04/14

A few people asked, so below is a picture of just a piece of my books closet.

From left to right:

  1. Object Professional 1.0 manuals volume 1-3
  2. BTree Filer 5.0 manual
  3. Turbo Professional manual (from 1985!)
  4. Borland Paradox Engine 3.0 manuals
  5. Crystal Reports Developers Edition
  6. Borland Open Architecture Handbook for Pascal
  7. Turbo Pascal 5.5 OOP Guide
  8. Turbo Pascal 5.5 Reference Guide
  9. Turbo Pascal 5.5 User’s Guide
  10. Turbo Pascal Quick Reference
  11. 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.

Delphi XE8 is out with version 22.0.19027.8951; Spring4D is almost ready.

Posted by jpluimers on 2015/04/09

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.
