Description

It would be amazing if node segment could check the existence of .nvm file and warning (change segment color) if current node version doesn't mach with .nvm version.

I'm learning go only for this :) but I guess need some help.

.nvm file is an easy extension (add it here), version file offset requires additional changes especially given that languages have the same base. But perfectly doable.

[roterob]

Yep, maybe is better take as base git segment... Let me know if there is a better approach.

@roterob I have the basis ready, can you give me the contents of .nvm?

[roterob]

The most common way to generate a .nvm file is node --version > .nvm. Is a file with the node version that the current project should use.
