support for --root option

[borisovg]

nyc doesn't seem to have support for --root option?

I keep all my test stuff in ./tests (including separate package.json and all coverage output) and run istanbul from this directory with --root ../ set.

@borisovg would definitely entertain adding this 👍

While implementing the --root option, I found that the NYC_CWD environment variable does almost exactly that (it still looks upwards for package.json).

I'm trying to migrate from istanbul and I'm also missing this feature.

Closing since this was fixed by #620

@borisovg since it's closed does it mean it has been released?

@Rush I'm using nyc 11.2.1 and --cwd is listed in the help output (in the bug I linked to it was decided that it is sufficient replacement for --root). I tried it today with my code and it seems to work fine.

@Rush should be working, there are a few bugs being addressed however feel free to join the conversation here:

#668

we seem to still have some issues when source-maps are remapping the directory structure.

I confirm the option itself is working but unfortunately it's useless to me without ability to provide a custom coverage dir for lcov. Istanbul has an option --dir custom-coverage-dir, for example --dir coverage/api

Oh, never mind, there's --report-dir
