[Lazarus] question with IDE

[Free Pascal - Lazarus mailing list]

my IDE sometimes decides that procedure X was not coded in the implementation section of a unit...and adds an empty definition

(see: https://imgur.com/awP7cK2)

The procedure is there (see https://imgur.com/6H5F2cG) but for some reason the IDE is brought to the crazy idea above.

This always happens with a couple of procedures, always the same.

Is there a way to avoid this weird behaviour?

Thank you

Peppe Polpo

Your existing implementation is missing the Paramter. Maybe that is the reason.

Do you have a complete example unit (you can strip the statements and
vars)?
Do you use IFDEFs?

I recently had this with fpc's deque.pp unit.
I added two methods to the intrface, then pressed Ctrl+C and it made
those two, but also a new empty implementation of
TDeque.IncreaseCapacity method (which already existst).
It's a generic class, if that matters at all.

Just for reference:
A similar report exists here:

See the attachment for two example units - obviously I cannot guarantee
it is the same scenario that duilio experiences but it is definitely an
example of Ctrl+Shift+C generating a duplicate method.

In general: if you delete a method A and add a method B to the interface
whereas A and B are of different types ("class constructor" vs
"constructor" vs "procedure/function") you get a duplicate.

I have known about this bug for a long time but have been too lazy to
fix it :(

No.
