## Usage
``gsc-tool [OPTIONS..] <path>``
- **path**: file or directory to process
- **options:**
``-m, --mode <mode>`` [REQUIRED] one of: `asm`, `disasm`, `comp`, `decomp`, `parse`
``-g, --game <game>`` [REQUIRED] one of: `iw5`, `iw6`, `iw7`, `iw8`, `iw9`, `s1`, `s2`, `s4`, `h1`, `h2`, `t6` `t7` `t8` `t9` `jup`
``-s, --system <system>`` [REQUIRED] one of: `pc`, `ps3`, `ps4`, `ps5`, `xb2` (*360*), `xb3` (*One*), `xb4` (*Series X|S*), `wiiu`
``-d, --dev`` Enable developer mode (dev blocks & generate bytecode map).
``-z, --zonetool`` Enable zonetool mode (use .cgsc files).
``-h, --help`` Display help.
``-v, --version`` Display version.
Example: ``gsc-tool -m comp -g iw5 -s pc ./data/iw5/my_fancy_script.gsc``
| Mode |Description | Output |
|:---------|:--------------------------|:------------|
|`asm` |assemble a `file.gscasm` |`file.gscbin`|
|`disasm` |dissasemble a `file.gscbin`|`file.gscasm`|
|`comp` |compile a `file.gsc` |`file.gscbin`|
|`decomp` |decompile a `file.gscbin` |`file.gsc` |
|`parse` |parse a `file.gsc` |`file.gsc` |
## File Format
If you need to extract scripts from fastfiles or game memory, use [Zonetool](https://github.com/ZoneTool/zonetool) or [Jekyll](https://github.com/EthanC/Jekyll).
- gsc-tool `.gscbin` binary format is a serialized ScriptFile struct: <br/>
- ***magic***: `"GSC\0"` 4 byte <br/>
- ***compressedLen***: 4 byte usigned integer <br/>
- ***len***: 4 byte usigned integer <br/>
- ***bytecodeLen***: 4 byte usigned integer <br/>
- ***buffer***: byte array[compressedLen] <br/>
- ***bytecode***: byte array[bytecodeLen] <br/>
note: for PS3 & Xbox 360 `.gscbin` files *(compressedLen, len, bytecodeLen)* are saved as little-endian!!
- zonetool (IW5) format made of bytecode file `.cgsc` and decompressed stack buffer `.cgsc.stack`.
- treyarch (T6) format is a single buffer with gscobj data `.gsc` or `.csc`.
## Build
- install [*premake5*](https://premake.github.io) on your system PATH
- clone this repository
- update the submodules ``git submodule update --init --recursive``
- run prebuild script ``premake5 vs2022`` (windows) or ``premake5 gmake2`` (linux/macos)
