[WayBack] A colleague and I was just wondering, why was TypInfo.pas not named TypeInfo.pas? The original theory of 8.3 naming convention doesn’t hold as TypInfo i… – Willo “qbitza” van der Merwe – Google+
Because of collision: though hardly documented in the early Delphi days the standard function TypeInfo has been there forever so System.TypeInfo already takes TypeInfo in the global namespace as the System unit is used by default and doesn’t have a namespace prefix.
One more reason to suffix unit names with a word like Unit.
And one more reason to always get a Delphi version with source code for RTL/VCL/…: it’s an invaluable source for not so well documented things.
The TypInfo name was also from an era when some people hadn’t learned yet dat using abbrvtns is a sin. Ken Thompson has learned [WayBack] spell it with an “e” · golang/go@c90d392 but we’re suck with StrPas, StrUtils, IntToStr and others forever like Unix is stuck with creat(2): [WayBack] creat(2): open/possibly create file/device – Linux man page and [WayBack] history – What did Ken Thompson mean when he said, “I’d spell creat with an ‘e’.” – Unix & Linux Stack Exchange.

Need to research {$DUPLICATEENABLE ON} further one day, but surely looks useful but is not really documented, not even at the Delphi 2009 documentation where it was introduced: [WayBack] SysUtils.pfIgnoreDupUnits Constant.

Via: [WayBack] MonkeyMixer has just been updated!- I’ve fixed a unit naming collision with Castlia- I’ve added an XE7 project group (which includes both the BPL and… – Simon Stuart – Google+
PS:
A cryptic G+ comment [WayBack] by Uwe Schuster:
DUPLICATEENABLE is old, but since it is something for IDE packages to avoid intersections with user/3rd party packages there is no need for a documentation. I do use it in an IDE package that did use the JCL/JVCL units as well and does another unit with a common name. IIRC I did mention it related to MonkeyMixer.
I think he argues that documentation is both not needed, but the usage of the directive sometimes is. Which somehow feels like a contradiction to me.
PS2: via Stefan Glienke, an error message that is related to this:
---------------------------
Error
---------------------------
Cannot load package 'Package2.' It contains unit 'Whatever', which is also contained in package 'Package1'.
---------------------------
OK

Any good English books similar to the German [WayBack] Agiles Coaching by Judith Andresen [Leanpub PDF/iPad/Kindle]?
Although my German reading is quite OK, it’s not OK enough to fully use this book.

The new [Archive.is] IDE Fix Pack 6.1 released | Andy’s Blog and Tools is huge, especially for Windows 10 targets:
Windows 10 Creators Update 1703 caused issues with all Delphi programs, libraries and packages because it changed how Windows loads imported DLLs in such a way that it causes performance issues and can crash the debugger.
Delphi 10.2 Tokyo Update 2 fixed this by not producing multiple dll import sections for one DLL anymore.
IDE Fix Pack 6.1 implements that “feature” for all previous Delphi versions (2009-10.1 Berlin) and extends it to not only eliminate duplicate dll imports but also duplicate delay dll imports.
There are also (optional) updates that you can enable with new compiler switches:
fwait instructions (but be careful, as they can confuse the debugger)There are some smaller changes too.
I’m going to try this soon.

I needed the script in [WayBack] Firebird – generate time/date/timestamp values to reproduce a problem in Database Workbench <= 5.3.2 with exporting TIME and TIMESTAMP values to Excel xlsx format: the time portion got lost so
1900-01-00 (I think the 00 is because of the infamous 1900 problem that also makes this hard: Excel worksheet function – How do I get the weekday name of a date?)The bug is fixed so will appear in the next beta and release versions: [WayBack] 0001506: Timestamp export to Excel XLSX only shows date, Time fails, CSV shows both date and time – Bug & Feature Tracker @ Upscene.com

A few tricks to write long strings to files when the Delphi debugger cuts them off (just because they like using 4k buffers internally);
TStringStream.Create(lRequestMessage).SaveToFile('c:\temp\temp.txt')TIniFile.Create('c:\a.txt').WriteString('a','a',BigStringVar)TFileStream.Create('c:\a.txt', fmCreate or fmShareDenyNone).WriteBuffer(Pointer(TEncoding.UTF8.GetBytes(BigStringVar))^,Length(TEncoding.UTF8.GetBytes(BigStringVar)))They all work form the debug inspector, but they do leak memory. See comments below.
