Error from importjs#ImportJSImport command

[flarnie]

When I try to use 'importJS' I have been seeing this error:

Error detected while processing /Users/paradasia/.vim/bundle/import-js/autoload/importjs.vim:
line 20:
SyntaxError: (eval):1:in require': /Users/paradasia/.vim/bundle/import-js/ruby/import-js/importer.rb:71: syntax error, unexpected '.', expecting kEND Error detected while processing function importjs#ImportJSImport: line 1: NoMethodError: undefined methodimport' for nil:NilClass
Press ENTER or type command to continue

I'm going to look into it a bit and see if I can find the problem. Since this does not happen on my work laptop, I assume it is related to something in how my environment is set up.

On line 71 in import-js/ruby/import-js/importer.rb there are some method calls that are split onto separate lines. I assume my version of Ruby doesn't like that syntax - when I moved those methods all onto one line the error went away.

Edit: Support for newlines after method calls was added in Ruby 1.9 so my Vim installation must be using an old version of Ruby.

@trotzig Moving the placement of the dot makes this backwards compatible with old Ruby versions, like so:

70 string.
71 gsub(/::/, '/').
72 gsub(/([A-Z]+)([A-Z][a-z])/, '\1_\2').
73 gsub(/([a-z\d])([A-Z])/, '\1_\2').
74 tr('-', '_').
75 downcase

However, this Ruby styleguide recommends keeping the dot as the prefix rather than placing it at the end like this. I agree that the 1.9 syntax is more readable.

Options:

• Update the README to expect users to have Ruby 1.9+ when using this plugin.
• Move to the old syntax and support older versions of Ruby.

I'll submit pull requests for each option.

It looks like you can use the commands :echo has('ruby') and :ruby puts RUBY_VERSION to inspect whether Vim has Ruby set up and what version it's running.1

Mine is using '1.8.7' which is probably just the system default. I'm going to try and set it to one of the more recent versions.
