Workflow CLI

The CLI is part of the Mailer repository.

go run ./cmd/mailer-workflow --file examples/workflows/order-totals.yaml

Flags

Flag	Purpose
`--file`	YAML or JSON workflow path. Required.
`--data-dir`	Base data directory for state and checkpoint defaults.
`--dry-run`	Parse, validate, resolve, and compile without executing.
`--describe`	Print the compiled pipeline description.
`--quiet`	Suppress the summary.

go run ./cmd/mailer-workflow \
  --file examples/workflows/order-totals.yaml \
  --dry-run \
  --describe

Use dry run before connecting service-backed workflows to Kafka or Postgres.

result, err := runner.RunFile(ctx, "workflow.yaml", runner.Options{
    BaseDataDir: "./data",
})

Use CompileFile when you want the compiled environment and metadata without executing the pipeline.
