| 2 | Minimal clang-rename integration with Vim. |
|---|
| 3 | |
|---|
| 4 | Before installing make sure one of the following is satisfied: |
|---|
| 5 | |
|---|
| 6 | * clang-rename is in your PATH |
|---|
| 7 | * `g:clang_rename_path` in ~/.vimrc points to valid clang-rename executable |
|---|
| 8 | * `binary` in clang-rename.py points to valid to clang-rename executable |
|---|
| 9 | |
|---|
| 10 | To install, simply put this into your ~/.vimrc for python2 support |
|---|
| 11 | |
|---|
| 12 | noremap <leader>cr :pyf <path-to>/clang-rename.py<cr> |
|---|
| 13 | |
|---|
| 14 | For python3 use the following command (note the change from :pyf to :py3f) |
|---|
| 15 | |
|---|
| 16 | noremap <leader>cr :py3f <path-to>/clang-rename.py<cr> |
|---|
| 17 | |
|---|
| 18 | IMPORTANT NOTE: Before running the tool, make sure you saved the file. |
|---|
| 19 | |
|---|
| 20 | All you have to do now is to place a cursor on a variable/function/class which |
|---|
| 21 | you would like to rename and press '<leader>cr'. You will be prompted for a new |
|---|
| 22 | name if the cursor points to a valid symbol. |
