What is the purpose of the ghci-dap wrapper?

[mpickering]

The purpose of the ghci-dap wrapper is not documented. My understand was that the program worked by spawning a ghci session (as specified by the user) and then sending commands to GHCi to interact with the debugger.

Forcing the use of the wrapper seems a lot less flexible.

The main purpose of ghci-dap is getting binding variable hierarchical detail information from ghci.

Almost debugging information can be gotten by parsing ghci pretty-printed string result.
Actually, phoityne-vscode.exe is doing this, as much as possible.
(although it is hard and difficult thing, because of flexibility of TEXT result.)

Bindings variable inspection is too hard by getting parsing repl TEXT result.
