NStrip

.NET Assembly stripper, publicizer and general utility tool

Note: This is less maintained than the BepInEx stripping tool available here: https://github.com/BepInEx/BepInEx.AssemblyPublicizer

Usage

The general usage of NStrip is NStrip [options] <input> (<output>). Input and output can be a file or a folder, but they have to match. Output is optional.

• -h | --help prints help text.
• -p | --public sets all types, methods, properties and fields to public.
• -n | --no-strip does not strip assemblies. If not used in conjunction with -p, this tool will write nothing.
• -d <folder> | --dependencies <folder> specifies a folder that contains additional dependencies for the target assemblies, if they are currently not in the same folder as the target assembly. Mono.Cecil will fail to output files if it cannot find all dependencies for the target assemblies. Can be specified multiple times
• -b | --blacklist is a blacklist for type name publicization. For example, -b "Type" will prevent types with the name "Type" from becoming public, which can help if types that are publicizised conflict with already public types and can cause issues with compilation.
• -o | --overwrite will overwrite target assemblies instead of appending -nstrip to the end of the filename. Does nothing if <output> is specified.
• -cg | --include-compiler-generated will publicize compiler generated members & types (they are not made public by default). -p is required for this to be useful.
  • --cg-exclude-events is used in conjunction with -cg if you wish to exclude event backing fields from being publicized, as they typically have the same name and can cause compilation issues.
• --keep-resources will not strip manifest resources when stripping an assembly.
• -t | --strip-type specifies the type of method body stripping that will be used:
  • ThrowNull: Makes all methods throw null. Runtime-safe and is the MS standard. Default.
  • ValueRet: Returns a dummy value and ret opcode. Largest but runtime-safe.
  • OnlyRet: Only adds a ret opcode. Slightly smaller than ValueRet but may not be runtime-safe.
  • EmptyBody: No opcodes in body. Slightly smaller again but is not runtime-safe.
  • Extern: Marks all methods as extern, and removes their bodies. Smallest size, but not runtime-safe and might not be compile-time safe.
• --remove-readonly removes the readonly attribute from fields. Only works with the mono runtime, other runtimes will complain about access violations.
• --unity-non-serialized prevents Unity from implicitly serializing publicized fields. For use within the Unity Editor
