## Usage
```yaml
jobs:
test:
runs-on: ${{ matrix.os }}
strategy:
fail-fast: false
matrix:
os: [ubuntu-latest, macos-latest, windows-latest]
toolchain:
- {compiler: gcc, version: 13}
- {compiler: intel, version: '2023.2'}
- {compiler: intel-classic, version: '2021.10'}
- {compiler: nvidia-hpc, version: '23.11'}
include:
- os: ubuntu-latest
toolchain: {compiler: gcc, version: 12}
exclude:
- os: macos-latest
toolchain: {compiler: intel, version: '2023.2'}
- os: macos-latest
toolchain: {compiler: nvidia-hpc, version: '23.11'}
- os: windows-latest
toolchain: {compiler: nvidia-hpc, version: '23.11'}
steps:
- uses: fortran-lang/setup-fortran@v1
id: setup-fortran
with:
compiler: ${{ matrix.toolchain.compiler }}
version: ${{ matrix.toolchain.version }}
- run: |
${{ env.FC }} ... # environment vars FC, CC, and CXX are set
${{ steps.setup-fortran.outputs.fc }} ... # outputs work too
```
## Options
- *compiler*: Compiler toolchain to setup, available options are
- *gcc* for `gfortran`
- *intel* for `ifx`
- *intel-classic* for `ifort`
- *lfortran* for `lfortran`
- *nvidia-hpc* for `nvfortran`
- *version*: Version of the compiler toolchain. See [runner compatibility](#runner-compatibility) charts below.
## Outputs
The action sets the following outputs:
- `fc`: Fortran compiler executable, e.g. `gfortran`
- `cc`: C compiler executable, e.g. `gcc`
- `cxx`: C++ compiler executable, e.g. `g++`
C/C++ compilers of the same toolchain/version are provided where available. If a standalone Fortran compiler is selected, the action will attempt to configure compatible C/C++ compilers (typically GCC, or MSVC on Windows), but this is not guaranteed — use at your own risk.
## Environment variables
The same values are also set as environment variables:
- `FC`
- `CC`
- `CXX`
Corresponding FPM environment variables are also set:
- `FPM_FC`
- `FPM_CC`
- `FPM_CXX`
These are made available to subsequent workflow steps via the [`GITHUB_ENV` environment file mechanism](https://docs.github.com/en/actions/learn-github-actions/environment-variables#passing-values-between-steps-and-jobs-in-a-workflow).
## Runner compatibility
Toolchain support varies across GitHub-hosted runner images.

**Note:** Intel's `ifx` compiler is not supported on macOS, so the `intel` option redirects to `intel-classic` (`ifort`).
**Note:** LFortran is currently only discoverable by name with `bash` on Windows, see [here for context](https://github.com/fortran-lang/setup-fortran/pull/57#issuecomment-2021605094).
