Hi,

After times I used Lazarus I still have a question about compiler mode. Why there is 5 mode?What can I do when I want objfpc mode benefits that is Lazarus default but for example I want advanced record syntax that can used with Delphi mode?
Can any one explain it to me or link me to a source?

Regards,
Ara

Split your unit in 2: one in objfpc mode and another in delphi mode.

Or use {$ModeSwitch advancedrecords}.

ModeSwitch is interesting.
But why they aren't in one mode?I mean all the good stuff in one mode?

What is 'good stuff' ? That depends on the person.

Also: you may want to control compatibility. If we added stuff that we think is fun, someone uses it in e.g. delphi mode without realizing Delphi doesn't support it, and suddenly his code no longer compiles in Delphi...

Like advancedrecords,
For many developers like me that Lazarus is going to be his/her main IDE and dont care code compatible with Delphi these are boring. For example Im using Delphi for 10 years and from the time Im using Lazarus I never need comparability.
I mean while Lazarus and FPC are going to be bigger its good to have a mode with all good stuff (again like advancedrecords in one place). But what I know! Im new here.

Because some of them are intersecting:
- Generics syntax in ObjFPC and Delphi mode are different
- Integer = SmallInt in TP/FPC mode, but LongInt in ObjFPC/Delphi mode

continue the list yourself by reading the docs

Mode Delphi doesn't even try to enforce delphi compatibility, so IMHO that is a stretch.

I would welcome a setting to generate $mode delphi units by default.
