How do I choose which indent format to use for same file type?

Question

I have multiple indent rules for same file type. I'd like to try them separately. How do I see which one is active? :set filetype is correct.

I did manage to change the rules by disabling all other indent files manually, but there probably is a better way?

In this case I have >5 different Javascript indent versions I'd like to test. (Mac default, Pangloss, web-indent, etc.)

Most indent files will either:

• set indentexpr and indentkeys;
• set cindent and cinoptions.

You can check the values by appending a question mark, and you can see where an option was set by prefixing it with :verbose. For example for JS:

:verbose set cindent?
  cindent
        Last set from /usr/share/vim/vim74/indent/javascript.vim
:verbose set indentexpr?
  indentexpr=

Or for Python:

:verbose set cindent? 
  nocindent
:verbose set indent
  indentexpr=GetPythonIndent(v:lnum)
        Last set from /usr/share/vim/vim74/indent/python.vim
