C/C++ Coding Style

For C/C++ files (*.c, *.cpp and *.h), we use clang-format (version 3.10) to ensure code styling. The rules and config files are included in the nf-interpreter repository.

Using Visual Studio Code

If you are using Visual Studio Code we suggest that you install the Clang-Format extension. To have this extension working you need to have the clang-format.exe installed on your system.

LLVM.org doesn't provide a separate installer for this tool so follows a quick and dirty way of getting it.

  1. Install the Clang-Format extension.
  2. Install the LLVM package from here.

    You may have to scroll down a bit. There aren't Windows builds for every version released. We are currently using v10.0.0.

  3. Take note of the path where you choose to install it.
  4. Back in VS Code, open the settings and adjust the entry for clang-format.executable with the path to the executable. The new setting file will have a new entry with something similar to the following:
"clang-format.executable" : "C:/Program Files/LLVM/bin/clang-format.exe"

You might have something slightly different in your setup. Just remember the following: add that setting, the path that you've copied before, change it to have forward slashes and add the clang-format.exe at the end.

After following the above steps successfully you can now right click on any C, C++ or H file and hit 'Format Document'. The VS Code extension will take care that the document is properly formatted according to the coding style guidelines.

Using Visual Studio

If you are using Visual Studio we suggest that you install the ClangFormat extension.
