It is an evolution of [WayBack] Sikuli Script – Home that has an other fork that can be automated with PowerPoint slides:

c# – All possible array initialization syntaxes – Stack Overflow

Posted by jpluimers on 2018/09/04

Since I tend to forget in-line array expression: [Archive.is] c# – All possible array initialization syntaxes – Stack Overflow:

These are the current declaration and initialization methods for a simple array.
string[] array = new string[2]; // creates array of length 2, default values
string[] array = new string[] { "A", "B" }; // creates populated array of length 2
string[] array = { "A" , "B" }; // creates populated array of length 2
string[] array = new[] { "A", "B" }; // created populated array of length 2
…
Also note that in the declarations above, the first two could replace the string[] on the left with var (C# 3+), as the information on the right is enough to infer the proper type. The third line must be written as displayed, as array initialization syntax alone is not enough to satisfy the compiler’s demands. The fourth could also use inference. So if you’re into the whole brevity thing, the above could be written as
var array = new string[2]; // creates array of length 2, default values
var array = new string[] { "A", "B" }; // creates populated array of length 2
string[] array = { "A" , "B" }; // creates populated array of length 2
var array = new[] { "A", "B" }; // created populated array of length 2

How and when are variables referenced in Delphi’s anonymous methods captured? – Stack Overflow

Posted by jpluimers on 2018/09/04

Just found some notes from 2013 for my research list that are still relevant:

Note that if you are using Smart Pointers, use the ones that Spring4D implemented in 2015 named Shared/IShared<T>/TShared<T>, see [WayBack] Spring4D – Pascal Today and [WayBack2] Smart Pointers will be in Spring4D 1.2.

Plastic SCM command-line for merge and diff

Posted by jpluimers on 2018/09/03

Just in case I have Plastic SCM without Beyond Compare:

Merge

"C:\Program Files\PlasticSCM5\client\mergetool" -b="%TEMP%\baseFile-guid.pas" -bn="baseSymbolicName" -bh="baseHash" -s="%TEMP%\sourceFile-guid.pas" -sn="srcSymbolicName" -sh="srcHash" -d="...\destinationPath\destinationFile.pas" -dh="destinationHash" -a -r="%TEMP%\resultFile.pas" -t="text" -i="NotIgnore" -e="NONE" -m="forced" -re="NONE" --progress="progressDescription" --extrainfofile="%TEMP%\extraInfoFile.tmp"

Diff

To be done

aa

Merge help (takes about 10 seconds to start):

"C:\Program Files\PlasticSCM5\client\mergetool.exe" --help

---------------------------
Mergetool usage
---------------------------
Usage: mergetool [ | ]

    diffOptions:  []

    mergeOptions:   [] [[] [] ] [] []

        baseFile:            {-b | --base}= 
        baseSymbolicName:    {-bn | --basesymbolicname}=
        automatic:           -a | --automatic
        silent:              --silent
        resultFile:          {-r | --result}=
        mergeType:           {-m | --mergeresolutiontype}={onlyone | onlysrc | onlydst | try | forced}

    generalFiles:  []  []

        sourceFile:          {-s | --source}=
        srcSymbolicName:     {-sn | --srcsymbolicname}=
        destinationFile:     {-d | --destination}= 
        dstSymbolicName:     {-dn | --dstsymbolicname}=

    generalOptions: [] [] [] []

        defaultEncoding:     {-e | --encoding}={none |ascii | unicode | bigendian | utf7 | utf8}
        comparisonMethod:    {-i | --ignore}={none | eol | whitespaces | eol&whitespaces}
        fileType:            {-t | --filestype}={text/csharp | text/XML | text}
        resultEncoding:      {-re | --resultencoding}={none |ascii | unicode | bigendian | utf7 | utf8}
        progress:            {--progress}=progress string indicating the current progress, for example: Merging file 1/8
        extraInfoFile:       {--extrainfofile}=path to a file that contains extra info about the merge

    Remarks:
          
        -a | --automatic:    Tries to resolve the merge automatically.
                             If the merge can't be resolved automatically (requires user interaction), the merge tool is shown.
        --silent:            This option must be used combined with the --automatic option.
                             When a merge can't be resolved automatically, this option causes the tool to return immediately
                             with a non-zero exit code (no merge tool is shown).
                             If the tool was able to resolve the merge automatically, the program returns exit code 0.

    Examples:

        mergetool
        mergetool -s=file1.txt -d=file2.txt
        mergetool -s=file1.txt -b=file0.txt --destination=file2.txt
        mergetool --base=file0.txt -d=file2.txt --source=file1.txt --automatic --result=result.txt
        mergetool -b=file0.txt -s=file1.txt -d=file2.txt -a -r=result.txt -e=utf7 -i=eol -t=text/csharp -m=onlyone
---------------------------
OK   
---------------------------

The merge extraInfoFile.tmp has a syntax like this:

Source (cs:-#)
    relative-sourceFile from cs:-# created by userName on timeStamp
    Comments: Source changeset description

Base (cs:#)
    relative-baseFile from cs:#@/baseBranch by userName on timeStamp
    Comments: BO's + CRUDS 

Destination (cs:#)
    relative-destinationFile from cs@/destinationBranch created by userName on timeStamp
    Comments: Destination changeset description

Where each cs is a change set number.

on the dB scales and audio

Posted by jpluimers on 2018/09/03

  • Double or twice the loudness = factor 2 means about 10 dB more sensed loudness level (psycho acoustic)
  • Double or twice the voltage = factor 2 means 6 dB more measured voltage level (sound pressure level)
  • Double or twice the power = factor 2 means 3 dB more calculated power level (sound intensity level)

Now that we’ve straightened that one out…

The Delphi VCL comes to Oxygene

Posted by jpluimers on 2018/09/03

Interesting approach, which makes one more “cross platform VCL” from outside the Embarcadero pipeline [WayBack] The Delphi VCL comes to Oxygene:

Developers switching from Delphi to Oxygene are loving our “Delphi RTL” compatibility library, as it helps them move their code over to new platforms without having to embrace all the new APIs at once. With the new Elements 10 builds we shipped in the past couple of weeks,

CrossVCL (by KSDev, the former FMX architects) already brings VCL to Linux through the Embarcadero compilers; VCL for Oxygene brings it – through the Oxygene compilers – to WebAssembly first and later to Cocoa and WPF.

I wonder how Windows VCL compatible both approaches are.

Delphi: delete temporary file after response dispatched – Stack Overflow

Posted by jpluimers on 2018/08/30

A while ago, Marjan Venema was in need for [Archive.is] Delphi SOAP: delete temporary file after response dispatched – Stack Overflow.

The solution there is a truly temporary file: a file stream that when the handle closes will have Windows delete the file by setting the correct flags.

The construct is functionally identical to the JclFileUtils.TJclTempFileStream [Archive.is].

It passes these [Archive.is] file attribute constant flags to the [Archive.is] CreateFileW Windows API function:

  • FILE_ATTRIBUTE_TEMPORARY
  • FILE_FLAG_DELETE_ON_CLOSE

I was glad she asked, though I wanted a temporary file to last after debugging, so I wrote code like this because internally the same FileGetTempName method is used by the JCL:

var
// ...
  TempPath: string;
  TempStream: TFileStream;
  TempStreamWriter: TStreamWriter;
begin
// ...
  TempPath := FileGetTempName('Prefix');
  TempStream := TFile.Open(TempPath, TFileMode.fmOpenOrCreate, TFileAccess.faReadWrite, TFileShare.fsRead);
  try
    TempStreamWriter := TStreamWriter.Create(TempStream);
    try
      TempStreamWriter.WriteLine('Debug starts:');
      MyStringList.SaveToStream(TempStream);
      TempStreamWriter.WriteLine();
// ...
      TempStreamWriter.WriteLine('Debug finishes.');
    finally
      TempStreamWriter.Free();
    end;
  finally
    TempStream.Free();
  end;

The truth about Eureka.(I say bollocks… A lot!)

I bumped into this a while ago, but since I’ve been doing quite a bit of research lately, it’s worth repeating.
