Hi. I'm working on adding Rust language support to lldb. One question that's come up is the best way to handle expression parsing.
On the one hand, it would be convenient to reuse an existing parser -- the one that we discussed was the "syn" crate. But, this is a Rust program. So then there's the question of how to ship it. Directly using the syn crate would mean having Rust code in-tree. Or, perhaps the Rust parts could be shipped as a shared library or an external executable. Are either of these doable? What do other language plugins do? My original plan here was to simply make the entire language support an external plugin. But, from what I can tell this isn't possible -- the necessary DWARF-related headers aren't installed. So maybe this could be changed? This would provide us with the most flexibility I think. A final idea is to do what I did for gdb, and simply write a new parser in C++. Doable, but for me I think a last resort. thanks, Tom _______________________________________________ lldb-dev mailing list lldb-dev@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev
