|
||
> [!IMPORTANT]
|
||
> tja2fumen is a tool designed for ***mod developers***. It allows developers to work with Taiko's official binary file format (`.bin`). If you are not a mod developer, and you simply want to play TJAs on Taiko no Tatsujin PC, please install and run [TakoTako](https://github.com/fluto/takotako).
|
||
|
||
> [!NOTE]
|
||
> TakoTako 3.2.0 includes an older, flawed tool called `tja2bin.exe`. If you have downloaded TakoTako 3.2.0, you should replace the old `tja2bin.exe` with the new `tja2fumen.exe`. This will ensure that your TJAs get converted accurately.
|
||
|
||
## Features
|
||
|
||
tja2fumen is designed to be an open source alternative to the closed source tja2bin tool that has been floating around various Discord servers. tja2fumen fixes several outstanding tja2bin issues, while providing an open source codebase to modify and learn from.
|
||
|
||
- Command line tool to convert `.tja` chart files to official fumen `.bin` files.
|
||
- Decodes official fumen `.bin` files (to inspect metadata and note data).
|
||
- Fix `.bin` files that were previously converted by `tja2bin` (WIP, see [#65](https://github.com/vivaria/tja2fumen/issues/65)).
|
||
- Uses strong development practices (thorough test suite with example charts, type checking).
|
||
- Provides an open source resource for the Taiko no Tatsujin fumen file format.
|
||
|
||
## Usage
|
||
|
||
### TJA conversion
|
||
|
||
To convert a `.tja` file to `.bin` files, simply download `tja2fumen.exe` and run:
|
||
|
||
```
|
||
tja2fumen.exe file.tja
|
||
```
|
||
|
||
### Decoding fumen charts in Python scripts
|
||
|
||
If you want to explore the song structure of existing `.bin` files or `.tja` files using Python scripts, run:
|
||
|
||
```
|
||
pip install tja2fumen
|
||
```
|
||
|
||
Then, you can use tja2fumen's Python API as follows:
|
||
|
||
```python
|
||
from tja2fumen.parsers import parse_fumen, parse_tja
|
||
|
||
fumen = parse_fumen("path/to/fumen_file.bin")
|
||
tja = parse_tja("path/to/tja_file.tja")
|
||
```
|
||
|
||
Please refer to `src/__init__.py` for further example usage of the Python API.
|
||
|
||

## Reporting bugs
|
||
|
||
If you've found a `.tja` file that tja2fumen converts incorrectly, please [open a new issue](https://github.com/vivaria/tja2fumen/issues/new) on the tja2fumen repo.
|
||
|
||
It is especially important that you attach the song files to the issue. You can do this by adding the song files to a `.zip` (Select files -> Right click -> "Send to" -> "Compressed (zipped) folder"), and then uploading the `.zip` to the issue. This greatly helps me to reproduce and fix any issues.
|
||
|
||
You can also message me directly on Discord (`_vivaria`) if you don't have a GitHub account, and I will take care of making an issue for you. :)

## Building on top of tja2fumen
|
||
|
||
If you are a developer looking to add tja2fumen to your project, you have two options:
|
||
|
||
1. For non-Python projects, you can download `tja2fumen.exe` and call it via a system call.
|
||
2. For Python projects, you can install tja2fumen via `pip install tja2fumen`.
|
||
|
||
tja2fumen uses a very permissable license ([MIT License](https://choosealicense.com/licenses/mit/)). You are free to distribute and modify tja2fumen, but please include a copy of the MIT License alongside the `tja2fumen.exe` executable if you copy it into your project.
