It seems like there's some problem with the existing ruby files, but other than that, I have no idea what's happening. After hitting enter to continue, things look ok, until you get 8-width spaces and no snipMate snippets completing, amongst other oddities.

I installed vim-ruby using plain old git submodule add into Pathogen's bundle folder, nothing fancy.

My regular vim is VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Jul 31 2011 19:27:29) with:

This also happens in MacVim, but one is unable to Interrupt in MacVim, thus it isn't possible to cancel out.

The backtrace leads us right to the line where ruby is invoked to determine the load path. Try

:echo system("ruby -e 'print $:.join(%q{,})'")

And see if it hangs the same way.

Nope, no hang. Just prints out this (with commas instead of these pretty newlines):

Same issue. Vim hangs with 100% CPU when opening ruby files. After ^C getting error: in /Users/kostiaka/.vim/bundle/vim-ruby/ftplugin/ruby.vim on line 82.

@tpope Following command also hangs:

:echo system("ruby -e 'print $:.join(%q{,})'")

@kostia does it hang if you run ruby -e 'print $:.join(%q{,})' from your shell? How about if you :! it in Vim?

kostia commented Nov 2, 2012

@tpope I found the source of my problem: it was a misconfigured PATH, which led to an endless loop when determining ruby bin. Sorry for disturbance.

@kostia Can you pls tell how you fixed the PATH? I tried ruby -e 'print $:.join(%q{,})' from shell and it does not hang. But my Vim hangs even if I do :ruby 1 (as a test case to test the whether vim works file with ruby). What exactly is the cause?

More info
:echo system("ruby -e 'print $:.join(%q{,})'")
does not hang.

Note that :ruby 1 uses the built-in if_ruby, which ftplugin/ruby.vim does not use. So there's a good chance your problem is unrelated.

@paramvir-b I don't know if it will help you, but I saw this same problem today when I had an unfortunate accident with my rvmrc file. I misremembered the command for creating an rvmrc file and rvm-auto-ruby was going into an infinite loop somehow. If you're using rvm, make sure that your rvm environment is a valid one https://rvm.io/workflow/rvmrc/
