This repository contains a cross-platform C++ "hello world" program designed to demonstrate the uses of GitHub actions.

We will write a GitHub action that will do the following:

• Ensure that the project builds
• Ensure source code is formatted (it's currently not)
• Check the above conditions on both Unix and Windows

1. Fork this repo and then clone your fork locally. This is critical - you're not working from a fork the actions you write won't be able to run.

If you have issues with this step, it's OK - this workshop is not about running or developing this program locally.

This project requires a C++ compiler and clang-format - if you already have both of these, skip to the next section!

sudo apt install build-essential clang-format

brew install clang clang-format

winget install llvm.llvm

./build.sh
./hello <your name>

. .\build.ps1
.\hello <your name>

1. Write GitHub action that checks for compiler errors and code formatting, and watch this fail
2. Format code locally and push (the checks should pass now)
3. Expand action to run on multiple platforms

• Ubuntu only workflow
• Cross platform workflow
