How does homebrew handle licensing data
10-26, 18:05–18:10 (Europe/Berlin), Main stage

Homebrew added license field support since 2.4.3 release, and since then, we have gradually included the licensing information into all the existing formulae. During this journey, we also work with SPDX team to include licensing information for the existing, very old formulae. Often the case, I would also reference the licensing information in the repology or upstream to get a direrct clarification. In this talk, I am gonna talk about the practices that we have done in the homebrew side and how we can collaborate.


  • Brief introduction about the licensing stuff
  • Homebrew's setup of licensing support
  • How did we handle the formula one by one
  • How to continuously monitor this
  • Discuss about SPDX, repology license, and clearlydefined
