default mode
« on: March 02, 2024, 06:54:56 pm »
hello,

I noticed that some simple units of mine ported from Delphi do not have any "mode" directive.
question: when no {$mode xxx} is specified which is the default one ?

thank you.

Hi
That would be {$mode fpc}
Regards Benny
If it ain't broke, don't fix it ;)
PCLinuxOS(rolling release) 64bit -> KDE5 -> FPC 3.2.2 -> Lazarus 2.2.6 up until Jan 2024 from then on it's: KDE5/QT5 -> FPC 3.3.1 -> Lazarus 3.0

Unless you are using Lazarus.
Then it would be ObjFPC ;)

Do note that only {$mode objfpc} is the default in Lazarus.
But also shortstring is default (for objfpc).
So {$mode objfpc}{$h-} is the complete default.

That's why you see almost always see {$mode objfpc}{$h+} at the top of the source.

For {$mode delphi} {$h+} isn't needed because h+ is the default in delphi-mode.

No, in Lazarus the default is {$H+}. These are the default options in Lazarus:

Ha, ok. What happens if you add only {$mode objfpc} at the top of the source code?
Will it revert back to {$h-} or will it keep {$h+}.

(Although I would always advice to add the mode and H at the top just to be sure 😊)

A $MODE-directive will change $H to the corresponding default state of that mode.
