Macro Recording and Common Macro Examples in Notepad++

# 1. Introduction

- 1.1 What is Notepad++?
- 1.2 The role and advantages of macros in Notepad++

# 2. Basic Operations of Macro Recording

Macro recording in Notepad++ is a very useful feature that can help users automate repetitive tasks and improve editing efficiency. The following section will introduce the basic steps of macro recording.

### 2.1 How to start the macro recording function?

To begin recording a macro, you can press `Alt` + `Shift` + `R`, or select `Macros` -> `Start Recording` from the menu bar. You can then start performing the operations you wish to record.

# Python example code
def example_function():
     # Example code for starting macro recording
     pass

### 2.2 How to end and save the recorded macro?

Once you have finished recording, press `Alt` + `Shift` + `R` again, or choose `Macros` -> `Stop Recording` from the menu bar. Notepad++ will prompt you to save the macro. You can name and save your macro.

// Java example code
public class MacroDemo {
     // Example code for ending and saving the recorded macro
}

### 2.3 How to use the recorded macro for automation?

You can execute the recorded macro by pressing `Alt` + `Shift` + `P`, or by selecting `Macros` -> `Run a Macro Multiple Times...` from the menu bar. You may also assign a shortcut key to call the macro more quickly.

// JavaScript example code
function runRecordedMacro() {
     // Example code for executing the recorded macro
}

With these basic operations, you can flexibly apply the macro recording feature in Notepad++ to improve editing efficiency and save time.

# 3. Introduction to Common Macro Examples

In Notepad++, macros can help us perform daily editing tasks quickly and enhance work efficiency. The following sections will introduce some common macro examples, which we hope will make your work easier.

#### 3.1 Deleting Blank Lines
Removing unnecessary blank lines from a text document is one of the common tasks we often need to perform during editing. By recording a simple macro, you can easily implement the operation of deleting blank lines.

# Macro for deleting blank lines
editor.beginUndoAction()
editor.selectAll()
editor.replace('\r\n\r\n', '\r\n')
editor.endUndoAction()

**Code Description:**
- First, the macro begins an undo action.
- Then, it selects the entire document content.
- Next, it replaces consecutive carriage return and line feed characters with a single carriage return and line feed character using the replace function.
- Finally, it ends the macro operation.

**Operation Result:**
- Extra blank lines are removed from the document, making it cleaner.

#### 3.2 Uniform Formatting of Code Style
In team collaboration, uniform code style is crucial. Below is a simple macro example for uniform code formatting.

// Macro for formatting code style
editor.beginUndoAction()
editor.selectAll()
selection = editor.getSelText()
formatted_code = selection.replace(/\s+/, ' ')
editor.replace(selection, formatted_code)
editor.endUndoAction()

**Code Description:**
- The macro begins an undo action.
- It selects the entire document content.
- It gets the selected text content.
- It replaces multiple spaces with a single space.
- It overwrites the original
