### Custom Argument Processing with Type Conversion (JavaScript)

Source: https://github.com/huliichuktaras/uplim-lang/blob/main/node_modules/commander/Readme.md

Details how to implement custom processing for command arguments using a callback function. This function, like `myParseInt`, receives the user input and previous value, returning the processed value. It's ideal for type conversion or validation. The example shows parsing integer arguments, with an optional default value.

```javascript
program
  .command('add')
  .argument('<first>', 'integer argument', myParseInt)
  .argument('[second]', 'integer argument', myParseInt, 1000)
  .action((first, second) => {
    console.log(`${first} + ${second} = ${first + second}`);
  });
```

### Configure Advanced Options in JavaScript

Source: https://github.com/huliichuktaras/uplim-lang/blob/main/node_modules/commander/Readme.md

This snippet shows how to use the `addOption` method with the `Option` constructor for more complex option configurations. It covers options with hidden help text, default values, restricted choices, environment variable integration, preset values, custom argument parsing, conflicting options, and implied options.

```javascript
program
  .addOption(new Option('-s, --secret').hideHelp())
  .addOption(new Option('-t, --timeout <delay>', 'timeout in seconds').default(60, 'one minute'))
  .addOption(new Option('-d, --drink <size>', 'drink size').choices(['small', 'medium', 'large']))
  .addOption(new Option('-p, --port <number>', 'port number').env('PORT'))
  .addOption(new Option('--donate [amount]', 'optional donation in dollars').preset('20').argParser(parseFloat))
  .addOption(new Option('--disable-server', 'disables the server').conflicts('port'))
  .addOption(new Option('--free-drink', 'small drink included free ').implies({ drink: 'small' }));
```

### Commander.js Program Initialization (CommonJS)

Source: https://github.com/huliichuktaras/uplim-lang/blob/main/node_modules/commander/Readme.md

Demonstrates two ways to initialize the Commander program object using CommonJS module syntax. The first uses a global 'program' object for simplicity, while the second creates a local 'Command' instance for better control and testability.

```javascript
// CommonJS (.cjs)
const { program } = require('commander');
```

```javascript
// CommonJS (.cjs)
const { Command } = require('commander');
const program = new Command();
```

### Advanced Color Conversion Examples

Source: https://github.com/huliichuktaras/uplim-lang/blob/main/node_modules/ansi-styles/readme.md

Provides specific examples of using the color conversion functions for different color spaces and ANSI palette targets (16, 256, 16 million). These functions allow for precise color mapping in terminal output.

```javascript
const style = require('ansi-styles');

style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code

style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code

style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
```

### UPLim Engine Data Flow Example

Source: https://github.com/huliichuktaras/uplim-lang/blob/main/docs/engine-specification.md

Illustrates the typical data flow when a developer writes UPLim code, from editor interaction through LSP to engine analysis and feedback.

```plaintext
1. Developer writes code in editor (VS Code)
2. Editor sends file content → LSP via Language Server Protocol
3. LSP calls Compiler API:
   - `parse` → AST
   - `analyze` → Diagnostics
4. Engine processes:
   - `analysis` collects metadata
   - `security` scans AST for vulnerabilities
   - `tester` runs performance benchmarks (background)
   - `evolver` uses `ai` + `storage` → generates language improvement proposals
5. LSP shows diagnostics, hints, quick fixes, recommendations
```
