# __dirname

> Base directory for binary executable paths

## Overview

The `OpenComicAI.__dirname` static property stores the base directory used to resolve paths to binary executables.

## Type

```typescript theme={null}
static __dirname: string
```

## Default value

Automatically set to the package's installation directory. Uses `__dirname` in CommonJS environments or `import.meta.dirname` in ES modules.

## Purpose

This property is used internally to locate platform-specific binary executables (realcugan, waifu2x, upscayl) included with the package.

## Setting custom dirname

You can override the default directory using `setDirname()`:

```javascript theme={null}
import OpenComicAI from '@opencomic/ai-bin';

// Set custom dirname
OpenComicAI.setDirname('/custom/path/to/binaries');

console.log(OpenComicAI.__dirname); // '/custom/path/to/binaries'
```

## Example usage

```javascript theme={null}
import OpenComicAI from '@opencomic/ai-bin';
import path from 'path';

// Get current dirname
console.log(OpenComicAI.__dirname);
// /Users/username/node_modules/@opencomic/ai-bin/dist

// Set custom dirname for portable installation
const appPath = process.env.PORTABLE_EXECUTABLE_DIR || __dirname;
OpenComicAI.setDirname(appPath);

// The binary paths are now resolved from the custom dirname
const binary = OpenComicAI.binary('realcugan');
console.log(binary);
// /custom/path/to/binaries/../mac/arm64/realcugan/realcugan-ncnn-vulkan.app
```

## Use cases

### Portable applications

```javascript theme={null}
// For Electron apps with custom binary locations
const { app } = require('electron');
const resourcesPath = path.join(app.getAppPath(), 'resources');
OpenComicAI.setDirname(resourcesPath);
```

### Development vs production

```javascript theme={null}
if (process.env.NODE_ENV === 'development') {
  // Use local build directory in development
  OpenComicAI.setDirname('./build');
} else {
  // Use package directory in production (default)
  // No need to set dirname
}
```

### Custom binary distribution

```javascript theme={null}
// If you're bundling binaries separately
const binaryPath = process.env.OPENCOMIC_BINARY_PATH || 
  path.join(process.cwd(), 'binaries');
OpenComicAI.setDirname(binaryPath);
```

## How it's used internally

The `__dirname` property is used by the `binary()` method to construct full paths to executables:

```javascript theme={null}
// Internal usage example
const binary = OpenComicAI.binary('realcugan');
// Constructs: path.join(__dirname, '..', 'mac/arm64/realcugan/realcugan-ncnn-vulkan.app')
```

## Path resolution

```javascript theme={null}
// setDirname converts relative paths to absolute paths
OpenComicAI.setDirname('./binaries'); // Converts to absolute path

// Absolute paths are used as-is
OpenComicAI.setDirname('/usr/local/opencomic/binaries');
```
