TSArP - Type-Safe Argument Parser
Copyright 2026 Ian Pilcher <arequipeno@gmail.com>
Overview
TSArP (pronounced like "zarp") is a wrapper around Python's argparse
module that supports static type-safety.
Limitations
TSArP is very much alpha software.
-
It currently supports only a fraction of the full functionality of
argparse. -
Python 3.14 or later is required.
-
Inheritance of schema attributes (types, groups, arguments, etc.) is not possible.
-
The API is very much in flux.
-
Lots of edge cases remain to be worked out.
Despite this, it is still useful.
Use
The basic usage pattern is:
-
Create any custom types (instances of
tsarp.Type). -
Create a schema (a subclass of
tsarp.Schema) for any subcommands and the top-level command-line interface. -
Call
tsarp.parse(), passing the top-level schema class as the first argument. -
tsarp.parse()returns an instance of the top-level schema class (containing instances of any subcommand schemas that were invoked).
