# WW Proto Dumper (Tree-Sitter ❤️ Reverse Engineering)
|
||||||
|
|
||||||
|
This is a PoC and demo to show how one can use tree-sitter on dumped javascript
|
||||||
|
netcode files for a certain game to extract fully intact proto files. To see its
|
||||||
|
potential, you can run the following (replace `"REPLACEME"` in enum_2.scm with `"e"`):
|
||||||
|
|
||||||
|
The Python code was my initial attempt at this, but my partially-implemented
|
||||||
|
matches API had a bug, so I just opted to go with Rust.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
tree-sitter query queries/message.scm example_protocol.js
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
tree-sitter query queries/enum.scm example_protocol.js
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
tree-sitter query queries/enum_2.scm example_protocol.js
|
||||||
|
```
|
||||||
|

# Tree-Sitter ❤️ Reverse Engineering
|
||||||
|
|
||||||
|
This is a repo that will be filled with examples and PoCs as I see fit of instances
|
||||||
|
where I've leveraged the power of tree-sitter to aid with reverse engineering.
