clang format

This page describes how to use and configure clang-format (v3.4). clang-format is a command line tool built on top of llvm that enforces whitespace conventions for c/c++ code. The configuration for it (.clang-format) is in the root directory of the repository and is discovered by the tool automatically. Mantid uses the llvm style.

Setting up git to format

There is a tool, git-clang-format which adds support to git to automatically format code that is added before it is committed. This only changes the formatting of the lines that you have already edited.
