Notepad++ is a versatile source code editor and text editor, but it doesn’t come with built-in, default keyboard shortcuts for automatic code formatting like some other IDEs (Integrated Development Environments). However, it offers powerful functionality through plugins that allows you to neatly format your code, making it more readable and maintainable. This tutorial will guide you through the options available for formatting code in Notepad++.
Understanding the Need for Code Formatting
Well-formatted code isn’t just about aesthetics. It significantly improves readability, making it easier to understand the logic and structure of your code. Consistent formatting also reduces errors and facilitates collaboration within teams. Languages like HTML, CSS, Python, and JavaScript all benefit from proper indentation and structure.
Formatting with Plugins
The primary method for automatic code formatting in Notepad++ involves installing and using plugins. Here are several popular options:
1. TextFX (HTML Tidy/Reindent)
TextFX is a collection of plugins that extends Notepad++’s functionality. It includes tools for formatting HTML, XML, and potentially other languages.
- Installation: TextFX is often pre-installed with older versions of Notepad++. If not, navigate to
Plugins > Plugins Adminand search for "TextFX". Select the plugin and click "Install". Restart Notepad++ after installation. - Usage: Select the code you want to format. Then, go to
TextFX > TextFX Edit > Reindent C++ Code. While named for C++, this option often works reasonably well for other languages as well. For HTML and XML specifically, you can also tryTextFX > TextFX Edit > HTML Tidy.
2. UniversalIndentGUI
UniversalIndentGUI is a powerful and versatile indenting tool that supports a wide variety of programming languages.
- Installation: Open
Plugins > Plugins Admin. Search for "UniversalIndentGUI" and click "Install". Restart Notepad++ after the installation is complete. - Usage: Select the code you want to format. Then, go to
Plugins > UniversalIndentGUI > Reindent. A configuration window will appear, allowing you to specify the language, indentation style (tabs or spaces), indentation size, and other options. Adjust the settings to your preference and click "Reindent".
3. XML Tools (Pretty Print)
While geared towards XML, the "Pretty Print" functionality within the XML Tools plugin can also be effective for formatting certain types of code, particularly those with a hierarchical structure.
- Installation: Open
Plugins > Plugins Admin. Search for "XML Tools" and click "Install". Restart Notepad++ after installation. - Usage: Select the code you want to format. Go to
Plugins > XML Tools > Pretty Print (XML only with line breaks). This will apply a basic formatting that adds line breaks and indentation to the selected code.
Choosing the Right Plugin
The best plugin for you will depend on the types of code you’re working with and your formatting preferences.
- UniversalIndentGUI is a great choice if you work with a variety of languages and need fine-grained control over the formatting settings.
- TextFX provides a quick and easy way to format code, especially HTML and XML.
- XML Tools can be useful for formatting structured data or code that resembles XML.
Additional Tips
- Select the Code: Always select the code you want to format before applying a plugin. This ensures that only the intended portion of the document is modified.
- Backup Your Code: Before using any formatting tool, it’s always a good practice to back up your code. This allows you to easily revert to the original version if something goes wrong.
- Experiment with Settings: Take the time to explore the configuration options available in each plugin. This will help you achieve the desired formatting results.
- Consistency is Key: Once you’ve chosen a formatting style, stick with it throughout your project. This will make your code more readable and maintainable.
By utilizing these plugins and techniques, you can effectively format your code in Notepad++ and improve your coding workflow.
