protodec
|
||||
========
|
||||
A tool to decompile protobuf classes compiled by [protoc](https://github.com/protocolbuffers/protobuf), from CIL assemblies back into .proto definitions.
|
||||
A tool to decompile protobuf classes compiled by [protoc](https://github.com/protocolbuffers/protobuf), from il2cpp compiled CIL assemblies back into .proto definitions.
|
||||
|
||||
This branch was created as a proof-of-concept using [the development branch of LibCpp2Il](https://github.com/SamboyCoding/Cpp2IL/tree/development/LibCpp2IL) to parse the game assembly and metadata directly, without the intermediate step of generating dummy DLLs.
|
||||
|
||||
I offer no guarantees that this branch functions 1:1 with master, it may explode.
|
||||
|
||||
Usage
|
||||
-----
|
||||
```
|
||||
Usage: protodec(.exe) <target_assembly_path> <out_path> [options]
|
||||
Usage: protodec(.exe) <game_assembly_path> <global_metadata_path> <unity_version> <out_path> [options]
|
||||
Arguments:
|
||||
target_assembly_path Either the path to the target assembly or a directory of assemblies, all of which be parsed.
|
||||
game_assembly_path The path to the game assembly DLL.
|
||||
global_metadata_path The path to the global-metadata.dat file.
|
||||
unity_version The version of Unity which was used to create the metadata file or alternatively, the path to the globalgamemanagers or the data.unity3d file.
|
||||
out_path An existing directory to output into individual files, otherwise output to a single file.
|
||||
Options:
|
||||
--debug Drops the minimum log level to Debug.
|
||||

@ -22,8 +28,9 @@ Limitations
|
|||
-----------
|
||||
- Integers are assumed to be (u)int32/64 as CIL doesn't differentiate between them and sint32/64 and (s)fixed32/64.
|
||||
- Package names are not preserved in protobuf compilation so naturally we cannot recover them during decompilation, which may result in naming conflicts.
|
||||
- When decompiling from [Il2CppDumper](https://github.com/Perfare/Il2CppDumper) DummyDLLs
|
||||
- The `Name` parameter of `OriginalNameAttribute` is not dumped. In this case, the CIL enum field names are used after conforming them to protobuf conventions
|
||||
- Due to the development branch of Cpp2Il not yet recovering method bodies
|
||||
- The `Name` parameter of `OriginalNameAttribute` is not parsed. In this case, the CIL enum field names are used after conforming them to protobuf conventions.
|
||||
- The `Tool` parameter of `GeneratedCodeAttribute` is not compared against when parsing gRPC service methods, which may cause false positives in the event that another tool has generated methods in the service class.
