This also moves all handling of message dispatch to the connection
object. That seems fine and the requirements of a "handler" are:
- implement OnEvent_<event> for any unsolicited events
Otherwise, requests are handled still by callbacks.
Maintain the variables in a simple tree and allow the user to
expand/collapse in the dumbest way possible. This means we don't
recursively consume all of the possible variable scopes.
This displays the entire hierarchy in a window. This is about as
inefficient as could possibly be, but for trivial things allows you to
see the variables at least.
UI is totally placeholder
Step over/step in are the only supported commands
Hardcoded launch config using a specific debug adapter that happened to
work
Adds a trivial log file hack and fixes the protocol handler for bytes
Very very basic inital checkin to show a way to talk to/from a Vim job
using python (mainly), and to parse the sort of messages that LSP and
VSCode debugger protocol speak (i.e. similar to http messages).
Very hacky, sort of holds together for what it is.
