Generates the 8-line wrapper migration file in priv/repo/migrations/
that delegates up/0 and down/0 to MailglassInbound.Migration.
Run once in the host application after adding :mailglass_inbound as a
dependency; idempotent (re-running is safe).
mix mailglass.inbound.gen.migrationThe generated file looks like:
defmodule MyApp.Repo.Migrations.MailglassInboundInstall do
use Ecto.Migration
def up, do: MailglassInbound.Migration.up()
def down, do: MailglassInbound.Migration.down()
endThe wrapper stays stable across mailglass_inbound versions. Per-version DDL
lives in MailglassInbound.Migrations.Postgres.VNN modules dispatched by the
runner; the wrapper never needs updating as mailglass_inbound evolves.
