Breakpoints in gem code

[tomdracz]

Playing around with the ruby debugger enabled by ruby-lsp and so far, so good for breakpointing inside my app.

I'm struggling to find a good way (or a way!) to try and debug inside the gem code.

Quite frequently I find myself digging into code pulled in installed gems. My usual approach using pry has been to just open a gem folder, stick binding.pry wherever I want a breakpoint to be and that was working OK. Can I achieve something similar with VSCode debugger and ruby-lsp?

@tomdracz if you open the file in the same VS Code workspace (e.g. by command-clicking on the filename in the backtrace) then you should be able to click in the margin and set a breakpoint within the gem.

Thanks @andyw8 That partially works, though still slightly clunky as I cannot find a way to dig into multiple files in a gem effectively. I've experimented with adding my gems folder to the workspace but ruby-lsp doesn't seem to be a fan of that and fails to initialise!

How about with the Dependencies View?

@andyw8 Ah this is exactly what I was looking for. Works like a charm, thanks!
