npm install -g @diekotto/code-digest
```

Then use the command from anywhere:

```bash
code-digest [options]
```

### Using NPX (No Installation)

| --------------- | ----- | ----------------------------------------------- | ------------------------- |
| `--directory`   | `-d`  | Directory to analyze                            | Current working directory |
| `--output`      | `-o`  | Output directory for generated files            | `code-digest-output`      |
| `--ignore`      | `-i`  | Additional patterns to ignore (comma separated) | -                         |
| `--gitignore`   | -     | Path to custom .gitignore file                  | `.gitignore`              |
| `--max-size`    | -     | Maximum file size in MB                         | 10                        |
| `--include-dot` | -     | Include dot files in the tree                   | `false`                   |
| `--format`      | `-f`  | Output format (json, text, or both)             | `text`                    |

## Examples

1. Generate digest for current directory:

```bash
code-digest
```

2. Generate digest for a specific directory with custom output location:

```bash
code-digest -d ./src -o ./output
```

3. Ignore specific patterns and set custom max file size:

```bash
code-digest -i "*.log,*.tmp" --max-size 5
```

## Output Files

The tool generates multiple files with a timestamp in the output directory:

- `metadata-{timestamp}.json`: Contains overall statistics and execution information
- `tree-{timestamp}.txt`: Text representation of the directory structure (if format includes 'text')
- `tree-{timestamp}.json`: JSON representation of the directory structure (if format includes 'json')
- `digest-{timestamp}.txt`: Detailed file information in text format (if format includes 'text')
- `digest-{timestamp}.json`: Detailed file information in JSON format (if format includes 'json')

### Output Format Details

#### Metadata File

Contains:

- Number of files processed
- Number of files skipped
- Total size of processed files
- Execution time
- Any errors encountered during processing

#### Tree Files

Provide a hierarchical view of your directory structure:

- Text format: ASCII tree representation
- JSON format: Nested object structure

#### Digest Files

Contain detailed information about each processed file:

- File path
- Size
- Type
- Other relevant metadata

## Error Handling

The tool will:

- Create output directories if they don't exist
- Skip files that exceed the maximum size limit
- Log errors for files that couldn't be processed
- Display a summary of any errors encountered during execution

## Exit Codes

- `0`: Successful execution
- `1`: Error occurred during execution

## Limitations

- Maximum file size is configurable but defaults to 10MB
- Dot files are excluded by default
- Follows .gitignore patterns by default
