roscpp Code Format

Why waste your valuable development time formatting code manually when we are trying to build amazing robots?

The repo contains an auto formatting script for the ROS C++ Style Guidelines.

Note: this style is in beta format, please submit suggestions or fixes!

Setup

Install clang_format:

sudo apt-get install -y clang-format-3.6
Then symlink or copy in the root of your catkin workspace the file .clang-format, located in this repo. You can save this file from this link. For example, place it on your computer here:

~/catkin_ws/.clang-format
If you are interested in improving this configuration file, we recommend you checkout the git repo and symlink, e.g.:

ln -s ~/roscpp_code_format/.clang-format ~/catkin_ws/.clang-format
Now any file inside your catkin workspace will be formatted with the ROS style guidelines described in this config file

Usage

You can run clang_format in several ways:

Command Line

Format single file:

clang-format-3.6 -i -style=file MY_ROS_NODE.cpp

Format entire directory recursively including subfolders:

find . -name '*.h' -or -name '*.hpp' -or -name '*.cpp' | xargs clang-format-3.6 -i -style=file $1

Emacs Editor Configuration

In your ~/.emacs config file, add the following:

Format your source code if its in some directory such as the catkin_ws (feel free to change keywords catkin_ws):

(defun run-ros-clang-format ()
  "Runs clang-format on cpp,h files in catkin_ws/ and reverts buffer."
  (interactive)
  (and
   (string-match "/catkin_ws/.*\\.\\(h\\|cpp\\)$" buffer-file-name)
   (save-some-buffers 'no-confirm)
   (shell-command (concat "clang-format-3.6 -style=file -i " buffer-file-name))
   (message (concat "Saved and ran clang-format on " buffer-file-name))
   (revert-buffer t t t)
))

Set a keyboard shortcut to run, such as F12

(global-set-key [f12] 'run-ros-clang-format)

Atom Editor Configuration

Install the clang-format package via the Atom package manager or apm install clang-format.
