Lack of Pascal support like with, local procedures, widestrings, dynamic arrays, properties is platform independend. Therefore all platforms would benefit.Are these things depending on the internal structures of GDB part and informations for the executables that is needed to be used under a GIU like Lazarus <or Eclipse> ) or is it just a shortcoming of the command line user interface of GDB ?
The internal structures of GDB don't allow for full Dwarf support, which is what is needed to fully support the Pascal language. Further, GDB would have to be enhanced to display data types as Pascal coders expect them.
Would it not be more appropriate to enhance GDB itself instead of setting up a completely new project.
Enhancing gdb has been done several times. Basically all Pascal support by GDB was written by our own Pierre Muller. However, there are several downsides:
- GDB does not accept patches from everyone - It takes a long time between patch submission and when people actually have such a gdb on their systems. - You cannot rewrite the GDB internals as an outsider to properly support Dwarf and thus Pascal
This seems to be a lot less work that "reinventing the wheel". I feel that Delphi language is not the only language that offers features like or similar to "local procedures, widestrings, dynamic arrays, properties". So this effort should be supported by the "powers " of GDB.
You will find many people are only interrested in C. People working on gdb are mainly employed by embedded Linux companies of which C is the primary language. They don't mind someone working on Pascal support, but don't expect them to start acticvely working on features for other languages.
