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
|
|
|
|
noremap <leader>cr :pyf <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.
