Show next "event"

[fredrikekre]

With Debugger.jl in the REPL I find the About to run: foo(...) status extremely useful. Is this something that can be displayed in neovim? I guess it might require some custom method implemented in DebugAdapter.jl (I could not find an official DAP request for this).

nvim-dap has support for extensions

==============================================================================
LISTENERS EXTENSIONS API                                       *dap-listeners*

nvim-dap supports subscribing and listening to all responses or events that a
debug adapter might send to nvim-dap.

...

Please refer to the Debug Adapter Protocol specification to get a list of all
events or requests and their response formats:

- https://microsoft.github.io/debug-adapter-protocol/specification#Requests
- https://microsoft.github.io/debug-adapter-protocol/specification#Events

For example:

>lua
  local dap = require('dap')
  dap.listeners.before['event_terminated']['my-plugin'] = function(session, body)
    print('Session terminated', vim.inspect(session), vim.inspect(body))
  end
<

Currently when I subscribe to event_stopped this is what I get for the body:

{
  reason = "step",
  threadId = 1
}

It looks like that message you are referring to is generated as part of Debugger.jl in https://github.com/JuliaDebug/Debugger.jl/blob/c0972c986a5cc0a335dad9888c4ac5eff1c848ce/src/printing.jl#L84

But DebugAdapter.jl to my understanding doesn't use Debugger.jl at all. If there's a similar event generated from DebugAdapter.jl we can set it up easily to subscribe to that event and print out a message in neovim.

No it doesn't but they both use JuliaInterpreter as the backend. We would have to copy the logic from Debugger to DebugAdapter.

I guess it is this type: https://microsoft.github.io/debug-adapter-protocol/specification#Events_Stopped in that case we can probably add this information as the description field or text field?

Yes, I think the events_stopped is the right place for this. I guess we should open an issue on DebugAdapter.jl, I won't get a chance to do it until later this week though.
