Machotools is a small set of tools built on top of macholib to retrieve and

change informations about mach-o files. Think of it as a pure python,

cross-platform implementation of install_name_tool

Examples::

        # Print the list of rpath defined in the given .dylib

        python -m machotools list_rpaths foo.dylib

        # Print the id (i.e. install_name) of the given .dylib

        python -m machotools install_name foo.dylib

        # Print the list of libraries linked in the given mach-o (simple otool

        # -L)

        python -m machotools list_libraries a.out

Internally, machotools is written as a library so that it can be used within

bigger tools, but the API is currently in-flux until the first 1.0 release.

Example::

        from machotools import rewriter_factory

        rewriter = rewriter_factory("foo.dylib")

        print rewriter.dependencies

        # install_name property only available if rewriter is a DylibRewriter

        # instance (auto-detected in rewriter_factory)

        print rewriter.install_name

        print rewriter.rpaths

        rewriter.install_name = "bar.dylib"

        # Changes are not actually written until you call commit()

        rewriter.commit()

        # When modifying a binary, one can also use context manager so that

        # changes are automatically committed when exciting the context.

        with rewriter_factory("foo.dylib") as rewriter:

            rewriter.install_name = "bar.dylib"

Main features:

        - ability to query/change rpath

        - ability to query/change the install name

        - ability to query/change the dependencies

        - should work on any platform supported by macholib (mac os x, unix,

          windows)

        - modifications are safe against crash/interruption as files are never

          modified in place. Instead, modifications are made against a

          temporary copy, and replace the original file using atomic rename on

          Posix (emulated on windows).

TODO:

        - support for multi arch

        - more detailed output for list_libraries (including versioning info)
