How to add screenshot to markdown/READMEs in github repository ? (via: Stack Overflow)

Posted by jpluimers on 2015/05/20

Adding relative links to screenshots in markdown files (like README.md) works way better at GitHub than on BitBucket:

For GitHub, this works, has documentation and various places with tips:

In fact it is a reason for some people to move public projects from Bitbucket to GitHub.

For private repositories that is different as GitHub charges for private repositories, but BitBucket has free private repositories.

Note: if you go the npm way, then you might want to have absolute URLs: Add images to readme.md in GitHub – Stack Overflow.

Dynamic DNS through NO-IP: keeping your hosts current, and your NO-IP account happy.

Posted by jpluimers on 2015/05/19

Now that DynamicDNS moved itself to a fully payed service, named it DynDns Pro, then renamed it Remote Access and limiting it to 30 hosts for USD 25 a year, I looked for alternatives, and noticed NO-IP.

I like it for a few reasons:

OK, last year, there was this Microsoft Legal Action and Controversy, but I think that is a once time thing (some people even argue that Microsoft wasn’t thinking), so I created the last script below in PowerShell.

A few open-source scripts to keep your NO-IP account happy (that also work on most other DDNS providers like Duck DNS):

Oh wow. Apparently all S3 buckets are also BitTorrent trackers.

Posted by jpluimers on 2015/05/16

Interesting:

There is no extra charge for use of BitTorrent with Amazon S3. Data transfer via the BitTorrent protocol is metered at the same rate as client/server delivery. To be precise, whenever a downloading BitTorrent client requests a “piece” of an object from the…

You can get torrent only for objects that are less than 5 GB in size.

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.

Batch file: Finds the location of xsd.exe by running the vsvars32.bat of the youngest installed Visual Studio

Posted by jpluimers on 2015/05/12

Boy, Microsoft made it hard to find the location of xsd.exe!

It is actually located like here:

C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\xsd.exe

But that is nowhere on the default path, nor in the registry.

What happens during installation of Visual Studio and/or the Microsoft SDK, is that the vsvars32.bat file of Visual Studio is updated so it can add the location of many tools (including xsd.exe) to the PATH.

So the trick is to find the youngest Visual Studio first, then run the according vsvars32.bat, and then xsd.exe is on the path.


:: Dynamically finds the installed xsd.exe, then calls it with the passed parameters
:: test these environment variables that have 110 or 120 in them (future enhancements: support more Visual Studio versions):
:: Visual Studio .NET 2002: VS70COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio .NET\Common7\Tools\
:: Visual Studio .NET 2003: VS71COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio .NET 2003\Common7\Tools\
:: Visual Studio 2005: VS80COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 8\Common7\Tools\
:: Visual Studio 2008: VS90COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\Tools\
:: Visual Studio 2010: VS100COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools\
:: Visual Studio 2012: VS110COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\
:: Visual Studio 2013: VS120COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\
:: They contain `vsvars32.bat` which will update the `PATH` so it includes where `xsd.exe` resides
setlocal enabledelayedexpansion
:: delayed expansion allows for the exclamation marks
:: see http://ss64.com/nt/delayedexpansion.html

Allow tests to be grouped by class, category, and namespace in Test Explorer – Customer Feedback for Microsoft

Usually I setup the grouping and filtering of the Test Explorer like this:

I really wish there was a multi-level grouping possibility here (:

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+.
