## Examples
### Basic usage
```yaml
steps:
- uses: actions/checkout@v4
- uses: minhqdao/setup-fortran@v1
- run: ${{ env.FC }} hello.f90 -o hello
```
This defaults to `gfortran` and the newest version available on that platform.
### Specific version
```yaml
- uses: minhqdao/setup-fortran@v1
with:
compiler: ifx
version: "2026.0"
```
### Matrix build
```yaml
strategy:
matrix:
os: [ubuntu-latest, macos-latest, windows-latest]
toolchain:
- { compiler: gfortran, version: "15" }
- { compiler: nvfortran, version: "26.3" }
- { compiler: lfortran, version: "0.63.0" }
exclude:
- os: macos-latest
toolchain: { compiler: nvfortran, version: "26.3"}
jobs:
test:
runs-on: ${{ matrix.os }}
steps:
- uses: actions/checkout@v6
- uses: minhqdao/setup-fortran@v1
with:
compiler: ${{ matrix.toolchain.compiler }}
version: ${{ matrix.toolchain.version }}
- run: ${{ env.FC }} hello.f90 -o hello
```
### Windows with MSYS2
```yaml
- uses: minhqdao/setup-fortran@v1
with:
compiler: lfortran
msystem: ucrt64
```
