RubyMarshal

Read and write Ruby-marshalled data. Only basics Ruby data types can be read and written:

float,
bool,
int,
str (mapped to rubymarshal.classes.RubyString if dumped with instance variables),
nil (mapped to None in Python),
array (mapped to list),
hash (mapped to dict),
symbols and other classes are mapped to specific Python classes.

Installation

    pip install rubymarshal

Usage

    from rubymarshal.reader import loads, load
    from rubymarshal.writer import writes, write
    with open('my_file', 'rb') as fd:
        content = load(fd)
    with open('my_file', 'wb') as fd:
        write(fd, my_object)
    loads(b"\x04\bi\xfe\x00\xff")
    writes(-256)

You can map Ruby types to Python ones:

    from rubymarshal.reader import loads
    from rubymarshal.classes import RubyObject

    class DomainError(RubyObject):
        ruby_class_name = "Math::DomainError"
    
    class_mapping = {"Math::DomainError": DomainError}

    loads(b'\x04\x08c\x16Math::DomainError', class_mapping=class_mapping)

You can use Ruby's symbols:

    from rubymarshal.reader import loads
    from rubymarshal.writer import writes
    from rubymarshal.classes import Symbol
    
    x = Symbol("test")
    dump = writes(Symbol("test"))
    y = loads(dump)
    assert y is x
