How to Create Your Own Command Line Code Generators

Creating command line tools can drastically improve your workflow, especially when dealing with repetitive tasks. If you’ve ever wanted to build your own command line code generators, similar to tools used in Rails, Sproutcore, and Webgen, you’re in the right place. Here is a comprehensive guide to help you get started.

The Challenge

Many developers face a common challenge: how to create a static directory structure with a single command. You’ve looked into frameworks like Rails or Sproutcore but haven’t found a clear path to develop your own streamlined solution. If you’re seeking to understand the basics and leverage the power of code generation, this guide will break down the necessary steps, ensuring you get on the right track.

Create a New Generator:
- Once you have Rubigen installed, you can generate a new template structure. Navigate to the directory where you want your generator, and run this command:
```
rubigen my_generator
```
- This will create a new directory named my_generator containing starter files for your generator.
Customize Your Templates:
- Now, you can customize the templates within your generator. Edit the generated files to fit the needs of your specific project. One of the best features of Rubigen is the ability to define how your files are structured and what they contain.
Testing Your Generator:
