## Build from Source

1. Clone this repository:

   ```
   git clone <repository-url>
   cd exportify-to-tunemusic
   ```

2. Build the project:

   ```
   cargo build --release
   ```

3. The binary will be available at `target/release/ett`

## Usage

### Single File Processing

Convert a single Exportify CSV file to TuneMyMusic format:

```
ett [INPUT_FILE] [OUTPUT_FILE]
```

Where:

- `[INPUT_FILE]` is the path to your Exportify CSV file (defaults to `exportify.csv`)
- `[OUTPUT_FILE]` is the path where the converted file will be saved (defaults to `converted_tunemymusic.csv`)

Example:

```
ett my_playlist.csv tunemymusic_output.csv
```

### Directory Processing

Process all CSV files in a directory:

```
ett --dir [INPUT_DIRECTORY] [OUTPUT_DIRECTORY]
```

or using the short flag:

```
ett -d [INPUT_DIRECTORY] [OUTPUT_DIRECTORY]
```

Where:

- `[INPUT_DIRECTORY]` is the directory containing Exportify CSV files
- `[OUTPUT_DIRECTORY]` is the directory where converted files will be saved

Example:

```
ett --dir ~/Downloads/playlists ~/converted_playlists
```

Note: You can also omit the `--dir` flag - the tool will automatically detect if the input is a directory:

```
ett ~/Downloads/playlists ~/converted_playlists
```

### Options

- `-d, --dir`: Process all CSV files in a directory
- `-h, --help`: Show help message
- `-V, --version`: Show version information

## Output Format

The output file will have the following columns, exactly matching TuneMyMusic's import format:

- Track name
- Artist name
- Album
- Playlist name
- Type
- ISRC
- Spotify - id
