### 4.1 Macro Recording and Playback

#### 4.1.1 Creating and Editing Macros

A macro is a pre-recorded series of operations that can be triggered via a shortcut key or menu command. In Notepad++, macros can be used to automate repetitive tasks such as text search, replace, or formatting.

To create a macro, go to the "Macro" menu and select "Start Recording." Then perform the sequence of operations to be recorded. Once done, go back to the "Macro" menu and select "Stop Recording." The recorded macro will be stored in the "Macro" list.

To edit a macro, select it from the "Macro" list and go to the "Macro" menu and select "Edit." This will open the "Macro Editor," where you can view and modify the macro's code.

#### 4.1.2 Executing and Debugging Macros

To execute a macro, select it from the "Macro" list and press the shortcut key or select "Run" from the "Macro" menu.

If there are issues executing a macro, you can use the "Debug" option in the "Macro" menu for debugging. This will open the "Macro Debugger," where you can execute the macro line by line and check variable values.

### 4.2 Script Writing and Execution

#### 4.2.1 Selection of Scripting Language

Notepad++ supports multiple scripting languages, including Python, Lua, and JavaScript. The choice of language depends on your specific needs and skills.

***Python:** A powerful and versatile language suitable for a wide range of automation tasks.

***JavaScript:** A popular language suitable for web-related tasks.

#### 4.2.2 Writing and Running Scripts

To write a script, go to the "Plugins" menu and select "NppExec." This will open the "NppExec" console, where you can input and run scripts.

# Python Script Example
import notepadpp
notepadpp.runMenuCommand("Edit", "Find")

-- Lua Script Example
notepad.open("test.txt")
notepad.find("Hello")

// JavaScript Script Example
document.getElementById("find-button").click();

To run the script, type it into the "NppExec" console or paste it in and then press Enter.

#### Code Logic Analysis

text = "John 25, Mary 30, Bob 40"
matches = re.finditer(pattern, text)
for match in matches:
     print(match.group("name"), match.group("age"))

- Using Python Libraries:

import pandas as pd

data = pd.read_csv("data.csv")
print(data["name"], data["age"])

**Text Data Statistics**

- Using Python Libraries:

import collections

text = "This is a sample text with repeated words."
counts = collections.Counter(text.split())
print(counts)

- Using Regular Expressions:

import re

pattern = r"\b(\w+)\b"
text = "This is a sample text with repeated words."
matches = re.findall(pattern, text)
counts = {}
for word in matches:
     counts[word] = counts.get(word, 0) + 1
print(counts)
