Notepad Line Numbers: Display Line Numbers

The steps to display line numbers in Notepad are: 1. Settings -> Preferences -> Editor -> Check "Show Line Number". Line numbering is crucial for programmers because it helps quickly locate and reference specific locations in code and improves productivity.

introduction

I have been with the code countless late nights, thinking hard about how to optimize my program. Once, I was editing a huge text file with Notepad, trying to find a specific line number, and it took a lot more time than expected. This made me realize how important it is to display line numbers in text editing. Today, I want to talk to you about how to display line numbers in Notepad and why this is crucial to programmers.

In this article, you will learn how to easily enable line number display in Notepad, and I will share some personal experiences about the importance of line number and usage skills.

Review of basic knowledge

Notepad is a free and powerful text editor, especially when dealing with code and large text files, its multi-tag interface and rich plug-in ecosystem make it a right-hand assistant for programmers. Line numbers play an important role in text editors, which helps us quickly locate and reference specific locations in our code.

Core concept or function analysis

Definition and function of line number

Line number is simply the number of each line in the text file. Its function is not only to help us quickly find a certain line, but also an indispensable tool when we communicate code with others. For example, when you mention "Please look at the code on line 42" to your colleagues, the line number can quickly focus on the focus of the discussion.

 // A simple C example #include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

In this example, if we mention line 3, the other party will immediately see the line #include <iostream> .

How it works

The line number in Notepad is implemented through UI settings, and it does not affect the file content itself. When row numbers are enabled, Notepad displays an additional column to the left of the editing area, showing the number of each row. This display is dynamic, and the line number will be updated as you scroll or edit text.

Example of usage

How to display line numbers in Notepad

To display line numbers in Notepad, the steps are very simple:

 Settings -> Preferences -> Editor -> Check "Show Line Number"

These steps will immediately display line numbers in your text editor, greatly improving your work efficiency.

Advanced Usage

In addition to basic line number display, Notepad also supports some advanced features such as bookmarks and folded code blocks. These features can be used in conjunction with line numbers to further enhance your editing experience.

 Settings -> Preferences -> Editor -> Check "Show Bookmarks"

Bookmarks allow you to quickly jump to marked line numbers, which is great for handling large files.

Common Errors and Debugging Tips

Sometimes, you may find that the line number cannot be displayed, which may be because you accidentally canceled the settings, or using a plug-in to interfere with the line number display. At this point, rechecking settings or disabling recently installed plugins usually solve the problem.

Performance optimization and best practices

When using line numbers, there are a few tips to help you work more effectively:

• Use shortcut keys : Notepad supports using shortcut keys to quickly jump to the specified line number, such as Ctrl G
• Keep the code neat : Although line numbers help position, if the code is too confusing, the effect of line numbers will be greatly reduced. Keeping the code neat and structured can make line numbers play a greater role.

Regarding the use of line numbers, my experience is that habitually using line numbers to record and communicate code issues can greatly improve the efficiency of team collaboration. At the same time, it is also very important to understand the limitations of line numbers. For example, in some cases, line numbers may fail due to code changes.

In short, line numbers play an indispensable role in text editing and code writing. Through this article, I hope you can better utilize the line number function in Notepad and improve your work efficiency.
