Hi llvm-dev,

I'm writing here to discuss the addition of D language plugin to LLDB.
Following the issue #52223 from Bugzilla, we are currently using C/C++
language plugin for D. This project is part of the Symmetry Autumn of
Code 2021, which proposes to implement better integration for D into

This project is a highly requested feature for D developers who use
Apple-based devices since configuring GDB requires extra configuration
and self signing binaries.

One possible solution is to write a plugin using the Python public API,
although it has some limitations, since, AFAIK, custom expressions are
not currently well supported.

More context about the project milestones can be found

I would like to discuss the possibility of upstreaming the plugin in
C++ to the official tree and if there is anything in the roadmap to
support custom expressions via Python.
