1 # This file is a minimal clang-format sublime-integration. To install: 2 # - Change 'binary' if clang-format is not on the path (see below). 3 # - Put this file into your sublime Packages directory, e.g. on Linux: 4 # ~/.config/sublime-text-2/Packages/User/clang-format-sublime.py 5 # - Add a key binding: 6 # { "keys": ["ctrl+shift+c"], "command": "clang_format" }, 7 # 8 # With this integration you can press the bound key and clang-format will 9 # format the current lines and selections for all cursor positions. The lines 10 # or regions are extended to the next bigger syntactic entities. 11 # 12 # It operates on the current, potentially unsaved buffer and does not create 13 # or save any files. To revert a formatting, just undo. 14 15 import sublime 16 import sublime_plugin 17 import subprocess 18 19 # Change this to the full path if clang-format is not on the path. 20 binary = 'clang-format' 21 22 # Change this to format according to other formatting styles 23 # (see clang-format -help). 24 style = 'LLVM' 25 26 class ClangFormatCommand(sublime_plugin.TextCommand): 27 def run(self, edit): 28 encoding = self.view.encoding() 29 if encoding == 'Undefined': 30 encoding = 'utf-8' 31 regions = [] 32 command = [binary, '-style', style] 33 for region in self.view.sel(): 34 regions.append(region) 35 region_offset = min(region.a, region.b) 36 region_length = abs(region.b - region.a) 37 command.extend(['-offset', str(region_offset), 38 '-length', str(region_length)]) 39 old_viewport_position = self.view.viewport_position() 40 buf = self.view.substr(sublime.Region(0, self.view.size())) 41 p = subprocess.Popen(command, stdout=subprocess.PIPE, 42 stderr=subprocess.PIPE, stdin=subprocess.PIPE) 43 output, error = p.communicate(buf.encode(encoding)) 44 if not error: 45 self.view.replace( 46 edit, sublime.Region(0, self.view.size()), 47 output.decode(encoding)) 48 self.view.sel().clear() 49 for region in regions: 50 self.view.sel().add(region) 51 # FIXME: Without the 10ms delay, the viewport sometimes jumps. 52 sublime.set_timeout(lambda: self.view.set_viewport_position( 53 old_viewport_position, False), 10) 54 else: 55 print error 56
