Sometimes you need to see two or more files with same name. In Emacs, buffer names confuse me a lot because they are like R.java, R.java<2>, R.java<3> and etc. You can make buffer name unique by using
uniquify.;
(require 'uniquify)
(setq uniquify-buffer-name-style 'post-forward
uniquify-separator ":")
There are several choices you can select for this
uniquify-buffer-name-style (Copied from documentation).
For example, files `/foo/bar/mumble/name' and `/baz/quux/mumble/name'
would have the following buffer names in the various styles:
- forward bar/mumble/name quux/mumble/name
- reverse name\mumble\bar name\mumble\quux
- post-forward name|bar/mumble name|quux/mumble
- post-forward-angle-brackets name name
- nil name name<2>
