Mob 0.7.12 has been released.

Fixed

  • ~MOB now raises a clear error when @foo is used without assigns in
    scope.
    The @foo → assigns.foo shorthand (0.7.11) only works inside a
    render(assigns); used in an ordinary helper function (positional args — the
    idiomatic composite pattern) it compiled to a cryptic “undefined variable
    assigns”. The sigil now guards with Macro.Env.has_var?(caller, {:assigns, nil}) (the same check Phoenix’s ~H uses) and raises a CompileError naming
    the fix ({title} instead of @title). Only @-using templates trigger it —
    a static ~MOB(<Text text="hi"/>) in a positional-arg helper still compiles.
    (MOB-5, #56)

Documentation

  • Worked component-authoring examples in the Components guide. The
    “Defining your own components” section now carries two complete, runnable
    screens — a function composite and a tag composite — spelling out the
    tag→atom rule and where on_* event-target auto-injection applies (a
    composite tag’s own props vs a plain widget in its children). The @assigns
    section documents that @foo only works where assigns is in scope and
    steers helpers to positional {var}. (#56, #57)
