CLI

Scope

This page is the flag interface for the mailwoman command-line interface. Each table is generated from the command's own schema, and each description is that flag's help text verbatim, so this page and mailwoman <command> --help cannot disagree.

The CLI has 177 commands. This page documents the 26 that a consumer of the published package runs. The rest build the datasets and train the modelsneural classifierThe machine learning model at the core of Mailwoman's parser — a transformer encoder (~30M parameters) trained from scratch to do BIO token classification over addresses. It learns the 'grammar' of address formats; the gazetteer supplies the 'atlas.' inside a checkout of the repository, and they are listed by group under Commands this page does not cover.

Three conventions apply to every table below.

• A flag written --no-<name> is on by default. Pass it to turn the behavior off.
• A default shown as environment-dependent resolves from the environment at run time. The flag's description states which variable it reads.
• A value in angle brackets in a synopsis is required. A value in square brackets is optional.

This page lists each command's synopsis and flags. For executed invocations with their real output, follow the tutorials and how-to guides linked under See also.

Rationale

This page is generated rather than written because a hand-maintained flag table is wrong the day a flag changes, and no check catches it. The generator reads the same command specifications that build the binary, so a flag string here is the flag string --help prints. A test asserts the committed page against a fresh render. A stale page therefore fails the build.

The scope split is deliberate. A page that covers all 177 commands would bury the 26 that run against an installed package under trainingtrainingThe process of adjusting a model's parameters so its predictions match labeled examples, by repeatedly measuring error and nudging the weights to reduce it. Distinct from inference, when the trained model is run on new input. and dataset tooling that requires the repository, its data root, and hours of wall clock. The generator refuses to run if it meets a command group it has never been told about, so the boundary is a decision someone makes rather than an omission.
