1 ''' 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 11 12 noremap <leader>cr :pyf <path-to>/clang-rename.py<cr> 13 14 IMPORTANT NOTE: Before running the tool, make sure you saved the file. 15 16 All you have to do now is to place a cursor on a variable/function/class which 17 you would like to rename and press '<leader>cr'. You will be prompted for a new 18 name if the cursor points to a valid symbol. 19 ''' 20 21 import vim 22 import subprocess 23 import sys 24 25 def main(): 26 binary = 'clang-rename' 27 if vim.eval('exists("g:clang_rename_path")') == "1": 28 binary = vim.eval('g:clang_rename_path') 29 30 # Get arguments for clang-rename binary. 31 offset = int(vim.eval('line2byte(line("."))+col(".")')) - 2 32 if offset < 0: 33 print >> sys.stderr, '''Couldn\'t determine cursor position. 34 Is your file empty?''' 35 return 36 filename = vim.current.buffer.name 37 38 new_name_request_message = 'type new name:' 39 new_name = vim.eval("input('{}\n')".format(new_name_request_message)) 40 41 # Call clang-rename. 42 command = [binary, 43 filename, 44 '-i', 45 '-offset', str(offset), 46 '-new-name', str(new_name)] 47 # FIXME: make it possible to run the tool on unsaved file. 48 p = subprocess.Popen(command, 49 stdout=subprocess.PIPE, 50 stderr=subprocess.PIPE) 51 stdout, stderr = p.communicate() 52 53 if stderr: 54 print stderr 55 56 # Reload all buffers in Vim. 57 vim.command("checktime") 58 59 60 if __name__ == '__main__': 61 main() 62
