We would like to thank all of you who have tried out the C/C++ extension in Visual Studio Code and have already provided
rich feedback on your experiences and filed issues and requests with us. We are working hard on incorporating your feedback
into the product. Continuing with our effort to make Visual Studio Code as the editor tool of choice for C++ developers with
this update of the C/C++ extension, we are introducing the following features:
• Code formatting with clang-format
• Fuzzy Auto-Complete for C/C++ code
• Debugging on Windows for Cygwin/MinGW applications
• Console application debugging with GDB on the Mac
• Toggle between Header/Source File (F4)
Now let’s dive into each one of these in more detail.
Code formatting with clang-format
You can now format your C/C++ code with clang-format from inside Visual Studio Code. Currently clang-format needs to be
installed manually and the path for clang-format needs to be added to user settings in Visual Studio Code as shown in the figure below.
By default, the clang-format style is set to ‘file’ which means it looks for a pre-existing. clang-format file, if the. clang-format file is found it
applies formatting settings specified in the file. If the. clang-format file is not found the default fallback-style specified in the c_cpp_properties.json file is used. The default fall back style is set to ‘LLVM’ today.
This clang-format behavior is controlled via the settings file ‘c_cpp_properties.json’ file which can be loaded and edited by executing the following command from the command palette.
Fuzzy Auto-Complete for C/C++ code
This update of the C/C++ extension in Visual Studio Code also introduces a preview version of a fuzzy Auto-Complete for C/C++ code. It’s based on an enhanced tag-parser approach, in other words no semantic analysis, so while it is not quite accurate it will still provide you more than what single-file intellisense provides you today. Additionally, this fuzzy intellisense approach will work pretty well for straight up C code so try it out and let us know what you think!
Debugging on Windows for Cygwin/MinGW applications
Another feature we are adding as a part of this update is the ability for developers to be able to debug their C/C++ Cygwin/MinGW applications using Visual Studio Code. Users can choose to attach to or launch the application to debug directly. In order to use cygwin or MinGW, the debugger path must be set manually in the launch configuration (launch.json). This is done via the ‘miDebuggerPath’ property, as the following figure shows:
Console application debugging with GDB on the Mac
In our previous release, we did not have the capability to debug console applications on the Mac using GDB. This has been added to this release. There are some known issues still, due to limitations with GDB. Please see the readme for more information.

Update your extension now!
If you are already using the C/C++ extension, you can update your extension easily by using the ext update dropdown. This will display any available updates for your currently installed extensions. To install the update, simply click the Update Extension button in the lower right for the outdated extension. You’ll be prompted to restart VS Code.
