Setting up a **cross-platform** environment for building and testing C++/C projects is a bit tricky. Each platform has its own compilers, and each of them requires a different installation procedure. This package aims to fix this issue.

This package is designed to be **modular** and as **minimal** as possible. This will allow you to install the tools you want. It is continuously tested on Windows, Linux, and macOS.

The package can be used locally or from CI services like GitHub Actions. Stay tuned for the stable release.

# Features

`setup-cpp` can install all of these tools:

- llvm
- gcc
- cmake
- ninja
- meson
- conan
- ccache
- cppcheck
- doxygen
- gcovr
- opencppcoverage
- python
- choco
- brew

# Usage

## From Terminal

You should download the exe file or the js file (if have Nodejs installed), and run it with the available options.

Tip: You can automate downloading using `wget`, `curl` or other similar tools.

### Executable

Download the executable for your platform from [here](https://github.com/aminya/setup-cpp/releases/tag/v0.1.1), and run it with the available options.

An example that installs llvm, cmake, ninja, ccache, and conan.

```ps1
# windows example (open shell as admin)
curl -O "https://github.com/aminya/setup-cpp/releases/download/v0.1.1/setup_cpp_windows.exe"
./setup_cpp_windows --compiler llvm --cmake true --ninja true --ccache true --conan "1.40.1"
```

```ps1
# linux example
wget "https://github.com/aminya/setup-cpp/releases/download/v0.1.1/setup_cpp_linux"
chmod +x setup_cpp_linux
sudo ./setup_cpp_linux --compiler llvm --cmake true --ninja true --ccache true --conan "1.40.1"
```

```ps1
# mac example
wget "https://github.com/aminya/setup-cpp/releases/download/v0.1.1/setup_mac_linux"
chmod +x setup_cpp_mac
sudo ./setup_cpp_mac --compiler llvm --cmake true --ninja true --ccache true --conan "1.40.1"
```

### With Nodejs

Download the `setup_cpp.js` file form [here](https://github.com/aminya/setup-cpp/releases/download/v0.1.1/setup_cpp.js), and run it with the available options.

On Windows

```ps1
# open shell as admin
wget "https://github.com/aminya/setup-cpp/releases/download/v0.1.1/setup_cpp_windows.exe"
node ./setup_cpp.js --compiler llvm --cmake true --ninja true --ccache true --conan "1.40.1"
```

On Linux or Mac:

```ps1
wget "https://github.com/aminya/setup-cpp/releases/download/v0.1.1/setup_cpp.js"
sudo node ./setup_cpp.js --compiler llvm --cmake true --ninja true --ccache true --conan "1.40.1"
```

## Inside GitHub Actions

Here is a complete cross-platform example that tests llvm and gcc. It also uses cmake, ninja, conan, cppcheck, and ccache.

`.github/workflows/ci.yml`:

```yaml
name: ci
on:
  pull_request:
  push:
    branches:
      - main
      - master

jobs:
  Test:
    runs-on: ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        os:
          - windows-2019
          - ubuntu-20.04
          - macos-10.15
        compiler:
          - llvm
          - gcc
    steps:
      - name: Setup Cpp
        uses: aminya/setup-cpp@v1
        with:
          compiler: ${{ matrix.compiler }}
          cmake: true
          ninja: true
          conan: true
          cppcheck: true
          ccache: true
          # add any tool that you need here...
```

In the `compiler` entry, you can specify the version after a `-`. For example, `llvm-11`.

For the tools, instead of `true`, which chooses the default version, you can pass a specific version.

### Incomplete

- [ ] msvc. It is implemented, but has bugs. See [this issue](https://github.com/aminya/cpp/issues/1)
- [ ] vcpkg (TODO)
