Nice. It's always exciting to see wider adoption through better editor integration. Out of curiosity, how does this compare to regular gud.el? (https://opensource.apple.com/source/lldb/lldb-69/utils/emacs/gud.el.auto.html)

We recently removed lldb-mi from the LLDB repository because nobody in the community was willing to maintain it. In particular the tests were so unreliable that most bots disabled them wholesale because they were so noisy. We had a GSoC student a year ago who was able to rewrite many of the tests in a more reliable fashion, but there were still a lot of issues outstanding after the project was completed. If you are interested in picking this up, it may be worthwhile to think about implementing lldb-mi 2.0 as thin python layer using the python SBAPI. Python may be a better choice for the kind of text-heavy glue-code that lldb-mi is. Alternatively it also shouldn't be hard at all to revive the existing C++ code. It's written in a different style than most of LLDB or LLVM (and IMO it should have never been accepted upstream in this form), but it shouldn't be hard to get building since it (thanks to the GSoC project!) is using only the stable public SBAPI.
