dev meeting 20201216

Agenda

• present: @emillon @NathanReb @pitag-ha

• 0.1.0 status:

  • made for https://github.com/realworldocaml/book/
  • good first use case because it does not build a releasable artifact
  • works with some limitations

• CI:

  • ocaml-ci supports opam-monorepo
  • it will:
    • detect the presence of opam-monorepo through the lockfile
    • compute the ocaml, dune, opam-monorepo version to install and run
    • run dune build @install
    • run dune runtest

• 0.2.0 plan:

  • just enough to support upgrading on RWO
  • most importantly, add transitive depexts to lockfile (#144)
  • this makes access to opam-repository unnecessary after the plugin is installed

• next use cases:

  • things which are released on opam
    • today this doesn't work since the opam file conflates specifications (how to produce a lock file) and dependencies (what opam will install)
  • Mirage unikernels

• compatibility is an important goal:

  • since opam plugins are global we want a single version to work with all projects
  • pull should handle former versions of the lock file
  • then mostly ok for lock to emit the latest format (the dune model)
  • this is a goal for 1.0.0
  • actually already the case for 0.1 and 0.2 formats, but might not be true for all 0.x releases
  • if needed, it might work to override the global plugin with a local install
