Posted by jpluimers on 2016/04/22
(:
“In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it.Whereas in the American system, the answer to “How much energy does it take to boil a room-temperature gallon of water?” is “Go fuck yourself,” because you can’t directly relate any of those quantities.

RubyMania has reached Delphi – Times helper method implementation for integers – from Asbjørn Heid
Posted by jpluimers on 2016/04/21
The below fragment is one of the favourite kinds of examples in the Ruby world:
5.times { |i| print i, " " }
It uses the times method on Integer and prints:
0 1 2 3 4
There are many implementations of this in other languages, for instance Ruby’s ‘times()’ function in C# | Of Code and Me (which the WordPress.com editor fucked up as it replaced Action<int> with Action which is a totally different thing, so the gist with code is below.
public static class IntExtensions
{
public static void Times(this int i, Action func)
{
for(int j = 0; j < i; j++)
{
func(j);
}
}
}
Which you use as
5.Times(i => Console.Write(i));
It’s slightly off as it prints:
01234
I know; nitpicking, but this code works (did I ever tell I love .NET fiddle?):
5.Times(i => Console.Write("{0} ", i));
Well, Mason Wheeler encouraged Asbjørn Heid for the below Ruby Mania in Delphi; just read the comments at In C# nearly everything is an object, so when writing a unit test for a string…
Since the WordPress.com editor fucks up TProc<Integer> into TProc and TProc behaves differently from TProc<Integer>, I’ve included a gist link with the actual code below.
program RubyManiaConsoleProject;
uses
System.SysUtils;
type
TRubyMania = record helper for ShortInt
procedure times(const IterBody: TProc);
end;
procedure TRubyMania.times(const IterBody: TProc);
var
i: Integer;
begin
for i := 0 to Self-1 do
IterBody(i);
end;
begin
5.times(
procedure(i: Integer)
begin
Write(i, ' ');
end
);
end.
It also shows why I hardly use anonymous methods in Delphi: they’re way too verbose.

XSD enumerations: restrict strings, integers, etc.
Posted by jpluimers on 2016/04/21
XSD enumerations are nice as they can be used to restrict simple XSD types to a set of values.
But they can also be hard if the set changes over time: restricting further is not possible, but extending isn’t always easy either.
Some interesting links:

Support of import in xsd.exe – Jose Luis Calvo Salanova – Site Home – MSDN Blogs
Posted by jpluimers on 2016/04/20
I tend to forget this: xsd.exe can resolve xs:include, but not xs:import. When using xs:import it will complain about missing types.
Simple solution: reference all imported XSDs (but not included XSDs) on the same command-line:
I was trying to create a C# class with xsd.exe from an schema that imports others schemas like that xsd.exe /c schema.xsd and it fails miserably reporting an error like “The datatype ‘xxx’ is missing.”. Basically xsd.exe doesn’t resolve the schemaLocation attribute.
Dare Obasanjo’s article addresses the problem, and Scott Hanselman had the same problem -and solved it-.
The solution isn’t very nice, but at least it’s simple. You have to tell xsd.exe all the schema referenced, xsd.exe /c schema.xsd importedSchema1.xsd importedSchema2.xsd
Be aware that the C# filename is sometimes generated from all XSD filenames on the command-line (I’ve noticed this when the import is specified before the actual XSD file, if the import is at the end, the name of the import is used.
If my memory serves me right, older versions of XSD.exe could not resolve unix-style relative paths on the command-line, but newer versions do.
