This would be an easy text-transformation that you could do in vim. Upon opening the file, translate all dashes without spaces "foo-bar" to add spaces "foo - bar". Then convert all underscores to dashes. "foo_bar" to "foo-bar". On save, invert the process.

You'd have to actually run the language's parser in order to do the transformation to avoid changing strings, and even then it'd only work if the parser output kept track of the original line and character so that you could know where to make the change.

This sort of text-transformation is something I've long wished my text editor did. At a previous job the standard was three-spaces of indent, regardless of the language.

Emacs does this in some cases: specifically for camelCasedWords (http://www.masteringemacs.org/article/making-camelcase-reada...) and for the word 'lambda' which can be displayed as a symbol. There are many other modes which "overlay" some text over how it looked originally.
