One thing to implement which is needed and easy at the same time is
support for turning paticular warnings and hints on/off in the code:
{$WARN identifier ON} / {$WARN identifier OFF} where identifier can be:
SYMBOL_PLATFORM, SYMBOL_DEPRECATED, UNIT_DEPRECATED, UNIT_PLATFORM,
UNSAFE_CODE OFF, UNSAFE_TYPE OFF, UNSAFE_CAST OFF, IMPLICIT_STRING_CAST,
...
I suggest to allow also ON/OFF by warning message ID. For example
{$WARN 5033 OFF} will turn off message "Function result does not seem to
be set".
Same to do with hints {$HINT message_id ON}/{$HINT message_id OFF}
although delphi does not support this.
Why it is easy:
1. fpc understand {$WARN} syntax while it currently do nothing
2. fpc allow to turn off warnings and messages by ID
Therefore your student will just need to complete already existed code.
Why not replace all the compiler directives, which are unknown to the
Delphi compiler, by a common different format, like {#PRAGMA WARN...},
and implement a general Pragma subsystem, where the FPC people could add
the functionality later, if this part is too time consuming for a
student project?
