Project description
Machotools is a small set of tools built on top of macholib to retrieve and change informations about mach-o files
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 print rewriter.install_name print rewriter.rpaths rewriter.install_name = "bar.dylib" # Changes are not actually written until you call commit() rewriter.commit()
Main features:
ability to query/change rpath
ability to query/change the install name
ability to query/change the dependencies
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).
Development happens on github
TODO:
support for multi arch
more detailed output for list_libraries (including versioning info)
