Syntax Highlighting Issue (SourceRequest)

[krmbzds]

Hello,

I use nvim-dap along with nvim-dap-ruby to debug Ruby code. With release 1.5.0 of debug.rb, syntax highlighting stopped working for me. I reported this in release issues of debug.rb and got some feedback regarding nvim-dap.

Quoting from ruby/debug#598 (comment):

• nvim dap support seems no coloring on src acquired by Source request (VSCode does). I think it should be fixed on nvim dap support (*1)

• To cancel Source request, localfs configuration should be added in launch.json on VSCode. This configuration is passed to DAP (debug.gem) by launch or attach request arguments (VSCode pass the configuration in arguments). But it is implementation defined way, and not sure nvim DAP support can pass these parameters.

• We can make further heuristics, for example assume localfs = true if host is localhost. But I'm not sure we can cover all of them (for example, 127.0.0.1 is not only local node IP address).

(*1) For example, eval'ed code should be acquired by Source request, so fixing it will help.

I started this discussion to pass-on the suggestions made by @ko1 as I do not have enough knowledge on either nvim-dap or debug.rb to open a proper issue for this. If anyone's generous enough to explain what's going on or suggest a workaround for this I'm all ears.

This is probably related to #334
