'''

Minimal clang-rename integration with Vim.

Before installing make sure one of the following is satisfied:

* clang-rename is in your PATH

* `g:clang_rename_path` in ~/.vimrc points to valid clang-rename executable

* `binary` in clang-rename.py points to valid to clang-rename executable

To install, simply put this into your ~/.vimrc for python2 support

    noremap <leader>cr :pyf <path-to>/clang-rename.py<cr>

For python3 use the following command (note the change from :pyf to :py3f)

    noremap <leader>cr :py3f <path-to>/clang-rename.py<cr>

IMPORTANT NOTE: Before running the tool, make sure you saved the file.

All you have to do now is to place a cursor on a variable/function/class which

you would like to rename and press '<leader>cr'. You will be prompted for a new

name if the cursor points to a valid symbol.
