Introducing Cora: A Powerful File Concatenation Tool for Developers

In the world of software development, we often find ourselves dealing with multiple files that need to be combined for various reasons. Whether it’s merging documentation, preparing training data for machine learning models, or consolidating code for review, the need to concatenate files is a common task. Enter Cora, a robust and flexible command-line tool designed to make file concatenation a breeze.

What is Cora?

Cora, which stands for COncatenate and Read All, is an open-source Go application that simplifies the process of combining multiple files into a single output file. With its intuitive command-line interface and powerful features, Cora is set to become an essential tool in every developer’s toolkit.

Key Features

Cora comes packed with features that set it apart from simple concatenation tools:

  1. Recursive Directory Traversal: Cora can walk through directories recursively, allowing you to process entire project structures with ease.

  2. Flexible File Selection: Use include and exclude patterns to precisely control which files are concatenated. This feature uses glob patterns, giving you powerful file matching capabilities.

  3. Customizable Output: Add separators between files and prefixes before each file path in the output, making the resulting file more readable and organized.

  4. Large File Handling: Cora is designed to handle large files efficiently, making it suitable for big data preprocessing tasks.

  5. Debugging Mode: Enable debug logging to get detailed information about the concatenation process, which is invaluable for troubleshooting.

Use Cases

Cora’s versatility makes it suitable for a wide range of scenarios:

  • LLM Context Preparation: When working with Large Language Models, Cora can help you prepare comprehensive context by concatenating relevant code files or documentation.

  • Code Review: Merge multiple source files into a single document for easier review, especially useful for pull request reviews or security audits.

  • Documentation Generation: Combine multiple markdown files to create comprehensive project documentation or technical specifications.

  • Log Analysis: Concatenate multiple log files for comprehensive analysis while using exclude patterns to filter out irrelevant files.

  • Data Preprocessing: Merge multiple data files into a single file for easier processing in data analysis pipelines.

Getting Started with Cora

Installing Cora is straightforward. If you have Go installed, you can use the following command:

go install github.com/shaharia-lab/cora@latest
Enter fullscreen mode
Exit fullscreen mode

Once installed, you can start using Cora with a simple command:

cora -s /path/to/source -o output.txt -i "*.md" -e "*.tmp"
Enter fullscreen mode
Exit fullscreen mode

This command will concatenate all Markdown files from the specified source directory, excluding any .tmp files, and save the result to output.txt.

The Power of Open Source

Cora is not just a tool; it’s an open-source project that welcomes contributions from the developer community. Whether you’re interested in adding new features, improving performance, or fixing bugs, your contributions are valuable and appreciated.

Conclusion

In a world where data is increasingly distributed across multiple files and formats, tools like Cora become indispensable. Its combination of simplicity and power makes it suitable for both quick, one-off tasks and integration into complex data processing pipelines.

We invite you to try Cora for your file concatenation needs and experience the difference it can make in your workflow. Visit our GitHub repository to get started, and don’t hesitate to share your feedback or contribute to the project.

Remember, in the world of development, small tools can make a big difference. Cora is here to simplify your file management tasks, allowing you to focus on what truly matters – building great software.

Happy coding!**
