gf VS debug-adapter-protocol

Oh! It's the person who made gf, the gdb frontend: https://github.com/nakst/gf

Small world.

A debugger can be really useful. (This one is good for linux: https://github.com/nakst/gf remedybg is good for windows)

Though I use Linux, so there isn't a lot of good debuggers, but I have found gf which is a GDB front-end for Linux, and it seams to work well.

Clion and vscode are decent. I've also heard good things about https://github.com/nakst/gf

I like gf (gdb frontend) https://github.com/nakst/gf

Recommend https://github.com/nakst/gf, extremely fast since it doesn't require it's frontend to run in your web browser.

The Language Server Protocol [1] is the best thing to happen to text editors. Any editor that speaks it gets IDE features. Now if only they'd adopt the Debug Adapter Protocol [2]...

Wonder if they've got support for Debug Adapter Protocol? https://microsoft.github.io/debug-adapter-protocol/

> Debuggers need to do more things

It's true that coming up with an interface for an abstract debugger is harder, but it's not impossible. Microsoft create Debug Adapter Protocol (https://microsoft.github.io/debug-adapter-protocol/), which is conceptually similar for LSP. It's not perfect, but covers most basic operations pretty well, while leaving to the debugger to deal with the implementation details.

Most languages also include support for the Debug Adapter Protocol, and Haskell is no exception, so if you are so inclined, you can hook up your favorite editor/IDE and go to town.

They're working on the Debug Adapter Protocol but it doesn't have critical mass/adoption yet. And yeah, I end up having a fair share of dbg!(foo). It's not so bad since dbg!() also returns its value, so you don't have to mess with your code too much.

TL;DR: What would it take to implement a Debug Adapter Protocol (DAP)-based step debugger?

RDP is the Windows Remote Desktop Protocol that was in use for decades before VSCode; VSCode's own remoting doesn't use it.

I'd say that, in addition to LSP, the other big thing that came out of VSCode is DAP: https://microsoft.github.io/debug-adapter-protocol.

The most important part is the JDT Languag Server, it will give you the Java tooling for writing code. I think it has DAP support as well, so with a DAP client like nvim-dap you should be able to debug as well.
