Brew formulas for Fortran

This repository provides package build instructions for tools and libraries around Fortran compatible with the Homebrew toolchain.

The lfortran compiler is installed from this tap:

brew install fortran-lang/fortran/lfortran

fpm and fortls are available from Homebrew directly:

brew install fpm
brew install fortls

Updating a formula

The daily version_detector workflow checks for new releases and opens a version-bump PR if it finds one.
The test workflow builds the formula from source on all supported platforms and uploads the bottles as CI artifacts. Wait until it is green.
Add the pr-pull label to the PR. Only do this after CI is green, otherwise bottles will be missing.
This triggers the publish workflow, which runs brew pr-pull: it downloads the bottles from CI artifacts, uploads them to a GitHub Release (creating it if needed), commits the bottle block to the formula, pushes to main, and cleans up the PR branch. Do not merge the PR manually.

The package build files are available under a BSD-2-Clause license.
