Motivation

I have this ruby project where I’m enforcing RuboCop and the way I do this is twofold:

  1. by using a pre-commit hook that runs RuboCop altogether.
  2. and with neomake so I can see errors/warnings right on my editor.

Today I noticed that the reported errors/warnings in my editor and the command line are not the same. What happened here?

Is it neomake issue?

I noticed that I had different versions of rubocop installed, because of reasons different projects have different versions of RuboCop.

But shouldn’t neomake use bundler exec?. Well maybe https://github.com/neomake/neomake/issues/2078, but there is a less obtrusive way.

direnv and bundler binstubs

I have already installed direnv, so what I did is:

  1. Generate the rubocop binstub:

    bundler binstubs rubocop

  2. Add the current path’s bin to the PATH env variable via my .envrc:

    export PATH=$(pwd)/bin:$PATH`

Conclusion

This fixed the problem. Now both my vim and command line are using the same version of RuboCop.
