Parse struct definitions like those used in the struct module

Project description

struct-parse

struct_parse builds on the struct_ module in the standard library. struct lets you parse buffers by describing the format similarly to C struct definitions. struct_parse aims to comply with the struct module's format strings, but instead returns a (very flat) abstract syntax tree (AST).

Example

.. code-block:: python

import struct_parse

field_list = struct_parse.parse('hhl') print(field_list.fields)

This will print::

[<FieldType.FLOAT: 16>, <FieldType.FLOAT: 16>, <FieldType.LONG: 9>]

Use cases

For simply unpacking packed binary data, the struct module does the trick. The goal of this module is to enable the user to do other stuff with the format string--we return a sequence of types instead of a sequence of values.

Compatibility

This library supports only Python 3.
