VSCode C++ config

Windows 10 (WSL -- Windows Bash) and Linux VSCode config for C++. Made for the subject PB161 at FI MU. (There is a branch that contains old PB071 stuff).

On Windows requires the Windows 10 Creators Update.

September 2019 update: Visual Studio Code now supports WSL remote workspaces, which I highly recommend over the hybrid method I describe below. Install WSL, VSCode will then prompt you on next start to install the WSL remote extension. A new button will appear in lower left corner, which you can use to connect to WSL. From then on, just follow the Linux instructions for everything. (Use the integrated terminal for that.)

How to install

1. Install VSCode, C/C++ extension and C/C++ IntelliSense (it will prompt you upon opening the first .c or .cpp file)
2. If on Windows, setup the WSL and install MinGW to C:/MinGW/ (needed for includes)
3. Open Bash and run the following command to install dependencies: sudo apt-get install gcc make cmake build-essential llvm clang clang-tidy libstdc++6-5-dbg libc6-dbg lcov
4. If on Windows, install the Windows version of Clang to use the code formatting (VS Code formatter can't use the WSL version)
5. Set the "C_Cpp.clang_format_path" VSCode setting -- usually "/usr/bin/clang-format" on Linux and "C:\\Program Files (x86)\\LLVM\\bin\\clang-format.exe" on Windows.

How to create a new project

1. Place all the files from this repo to your new C++ project folder
2. Open the project folder in VS Code (directly, don't open a parent folder)

Debugging

Switching to debugging tab and pressing the green play button triggers a build and debug. You can choose either "Main" or "Test" configuration.

On Windows, input and output will go to /dev/tty1 -- simply open a single Bash window and run sh there, and then check that you're on tty1 using the command tty. After that, you can start debugging.

You can add arguments and redirect input/output by editing the property "args" in launch.json.

Test coverage

Install the Coverage Gutters extension to VSCode. Then run task coverage and show the coverage gutters using the new statusbar button.

Available commands (CTRL-P)

• task build -- builds the project
• task tests -- builds and runs tests, then underlines failed tests
• task tidy -- runs clang-tidy on the current opened file and underlines the errors
• task fix -- like task tidy, but instead of underlining tries to fix the errors automatically
• task coverage -- generates the code coverage analysis file (lcov.info)
