mix format failed for file: test/fixtures/example.exs

    error: invalid character "o" after number 0. If you intended to write a number, make sure to separate the number from the character (using comma, space, etc). If you meant to write a function name or a variable, note that identifiers in Elixir cannot start with numbers. Unexpected token: o

That's weird. The tests pass locally for me 🤔

[kianmeng]

It works in local dev (1.18, 27, ubuntu 24.04) for me as well, not in CI job, test (1.12, 22, ubuntu-20.04). See https://github.com/kianmeng/makeup_eex/actions/runs/13182353912/job/36796042560

[josevalim]

Should we bump the minimum Elixir version?

[kianmeng]

Same with test (1.13, 22, ubuntu-20.04) if we make makeup_html an optional deps, {:makeup_html, "~> 0.1.0 or ~> 1.0", optional: true},:

See https://github.com/kianmeng/makeup_eex/actions/runs/13191664881/job/36825616496

[josevalim]

Oh, I know what it is. Earlier Elixir versions did not start optional dependencies automatically. So we need to either bump the Elixir version more or add Application.ensure_all_started(:makeup_html) to test/test_helper.exs.

@kianmeng could you kindly send a PR for adding CI to makeup_json and makeup_c?
