# GitHub Action


msvc-kit provides an official GitHub Action for easily setting up the MSVC build environment in CI/CD pipelines.

## Basic Usage


```yaml
name: Build

on: [push, pull_request]

jobs:
  build:
    runs-on: windows-latest
    steps:
      - uses: actions/checkout@v4

      - name: Setup MSVC Build Tools
        uses: loonghao/msvc-kit@v1
        with:
          arch: x64

      - name: Build
        run: |
          cl /nologo test.c
```

## Specific Versions


```yaml
      - name: Setup MSVC Build Tools
        uses: loonghao/msvc-kit@v1
        with:
          msvc-version: "14.44"
          sdk-version: "10.0.26100.0"
          arch: x64
```

## Matrix Build


```yaml
name: Matrix Build

on: [push]

jobs:
  build:
    runs-on: windows-latest
    strategy:
      matrix:
        arch: [x64, x86, arm64]
    steps:
      - uses: actions/checkout@v4

      - name: Setup MSVC Build Tools
        id: msvc
        uses: loonghao/msvc-kit@v1
        with:
          arch: ${{ matrix.arch }}

      - name: Show installed versions
        run: |
          echo "MSVC: ${{ steps.msvc.outputs.msvc-version }}"
          echo "SDK: ${{ steps.msvc.outputs.sdk-version }}"
          echo "cl.exe: ${{ steps.msvc.outputs.cl-path }}"
```

## With Caching


```yaml
      - name: Cache MSVC
        uses: actions/cache@v4
        with:
          path: ${{ steps.msvc.outputs.install-dir }}
          key: msvc-${{ matrix.arch }}-${{ steps.msvc.outputs.msvc-version }}

      - name: Setup MSVC Build Tools
        id: msvc
        uses: loonghao/msvc-kit@v1
        with:
          arch: ${{ matrix.arch }}
```

## Rust + cc-rs Integration


The action automatically sets `CC` and `CXX` environment variables for seamless Rust/cc-rs compatibility:

```yaml
      - name: Setup MSVC Build Tools
        uses: loonghao/msvc-kit@v1
        with:
          arch: x64

      - name: Build Rust project with C dependencies
        run: cargo build --release
```
