It’s a REPL for the Neovim Lua interpreter with a little twist: It’s using the Debug Adapter Protocol. And before that, I worked on hprofdap. Also a kind of a REPL using DAP that lets you inspect Java heap dumps (.hprof files) using OQL.

As the name might imply, a REPL isn’t the main use case for the Debug Adapter Protocol (DAP). From the DAP page:

The idea behind the Debug Adapter Protocol (DAP) is to abstract the way how the debugging support of development tools communicates with debuggers or runtimes into a protocol.

But it works surprisingly well for a REPL interface to a language interpreter too.

Both regular Lua, but also Lua that uses Neovim as Lua interpreter. The latter is interesting if you want to debug Neovim plugin test cases written using busted
