Backtrace when trying to run spec for the current line

[timofurrer]

Disclaimer: I'm not ruby expert 🙈

My nvim-dap-ruby setup generally works - verified using some very dummy project. However, with a larger code base (GitLab rails in this case), which takes several seconds to spawn the rspec the following happens:

Ruby REPL: You can run any Ruby expression here.
Note that output to the STDOUT/ERR printed on the TERMINAL.
[experimental]
  `,COMMAND` runs `COMMAND` debug command (ex: `,info`).
  `,help` to list all debug commands.

Run options: include {:focus=>true, :locations=>{"./ee/spec/services/clusters/agent_tokens/create_service_audit_log_spec.rb"=>[27]}}

Finished in 1.83 seconds (files took 18.84 seconds to load)
0 examples, 0 failures, 1 error occurred outside of examples

What's going wrong here and how can I fix it?

Is this because of this waiting configuration:

https://github.com/suketa/nvim-dap-ruby/blob/0a18182c6e5ee62b690b0c6ace155e4bbc4cd37f/lua/dap-ruby.lua#L168

... which would interrupt the session after a second?

[suketa]

I'm not sure, but...

nvim-dap-ruby invokes rdbg process which run your spec and try to connect to rdbg process after waiting milliseconds.

But, nvim-dap-ruby might fail to connect the rdbg process because the larger code base takes more time to finish starting process.

It might work if waiting is larger.

I don't know smarter way to wait rdbg process started.

It might work if waiting is larger.

What do you think about making that waiting value configurable on a per workspace basis?
