Hello
I have 1M lines file. CudaText (Lazarus app) cannot delete lines fast [selected 800K lines]. Reason: TFPSList has only Delete for one item.
Need DeleteRange for many items.
Regards,
Alexey

I'm not sure that it will help you: for many cases the list will need to delete the elements one by one anyway, for instance for interfaces. Or when a notification of an operation is requested.
But we can consider it, so please post a feature request in the bugtracker.
Michael.
Hi Michael Van,
delete the elements one by one anyway, for instance for interfaces.
that can still be speed up by range deletion. First call _Release on them all, then remove them with move/fillchar.
Bye,
Benito
Pls, call Deref for all items (1 by 1), by REALLOC all items [e.g. 800K] as block. Today I call Delete 800K times and do realloc 800K times :(
