Why won't macvim always use ruby 1.9.3?

I have installed yadr dotfiles, a set of vim, ruby, etc plugins.

I have the following line of Ruby code in a file foo.rb:

foo: bar

Note I used the ruby 1.9.3 syntax for symbol assignment/definition.

When I start macvim from command line using mvim foo.rb and save that file, everything works fine.

However, when I open macvim using open -a macvim and navigate to and open foo.rb, when I try to save the file I get a ruby-vim syntax error on foo: bar. When I change it to :foo => bar I don't get syntax errors.

  • Using open -a macvim to open macvim, and then entering :!ruby -v prints ruby 1.8.7
  • Using mvim . to open macvim, and then entering :!ruby -v prints ruby 1.9.3

Depending on how I open macvim, I get a different version of Ruby. How do I ensure that macvim always uses ruby 1.9.3 to evaluate my ruby code?

Thanks

What does :!echo $PATH show in each? - kejadlen
I won't post it as an answer because I forgot most of the details but the two methods are loading different environment variables: mvim file uses your shell's environment while open -a macvim files uses your system's environment. But why would you use it? mvim is infinitely better. - romainl

It took me awhile to find a fix, but the issue is caused by MacVim not loading zsh the same way Terminal loads zsh.

The fix is easy enough and can be placed into your zshrc. See a commit from my dotfiles:

The commit references a full explanation which can be found here:

Hope this helps!
