Frequently Asked Questions Answers in the Development of Java Library: Marked framework related
Marked is a popular JavaScript library for analysis and conversion of MarkDown text.In the development of the Java library, using the MARKED framework may encounter some common problems.This article will answer some common questions related to the MARKED framework and provide corresponding Java code examples.
Q1: How to use the MARKED framework in Java?
A: To use the MARKED framework in Java, first of all, you need to introduce related JavaScript files in the project.You can use Java's scriptengine to load and execute these files.The following is a simple example:
import javax.script.*;
public class MarkedExample {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
// Load the MARKED library
engine.eval(new java.io.FileReader("path/to/marked.js"));
// Use marked analysis of Markdown text
String markdownText = "# Hello, Marked!";
String script = "marked('" + markdownText + "');";
String html = (String) engine.eval(script);
System.out.println(html);
}
}
In the above examples, we use scriptengineManager and scriptengine to load and execute the Marked library.By calling the Engine.eval method, we can execute the JavaScript code and use the MARKED function to parse the Markdown text.
Q2: How to customize the analysis of the MARKED framework?
A: The MARKED framework provides many options and extensions, which can be used to customize parsing behavior.In Java, we can customize by passing a option object to the MARKED function.The following is an example:
import javax.script.*;
import jdk.nashorn.api.scripting.*;
public class MarkedExample {
public static void main(String[] args) throws Exception {
ScriptEngine engine = new NashornScriptEngineFactory().getScriptEngine();
// Load the MARKED library
engine.eval(new java.io.FileReader("path/to/marked.js"));
// Customized parsing behavior
String markdownText = "# Hello, Marked!";
String script = "marked('" + markdownText + "', { gfm: true });";
String html = (String) engine.eval(script);
System.out.println(html);
}
}
In the above example, we use NashornScriptengineFactory to create the Scriptengine object and load the MARKED library.Then, we customize the analysis of the behavior by passing a option object to the MARKED function.In this example, we set the GFM option to True to enable the Github -style Markdown parsing.
Q3: How to convert Markdown text into HTML files?
A: To convert the Markdown text into an HTML file, you can use the Marked framework to parse the Markdown text, and then write the result into a HTML file.The following is an example:
import javax.script.*;
import java.io.*;
public class MarkedExample {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
// Load the MARKED library
engine.eval(new java.io.FileReader("path/to/marked.js"));
// Use marked analysis of Markdown text
String markdownText = "# Hello, Marked!";
String script = "marked('" + markdownText + "');";
String html = (String) engine.eval(script);
// Write the result into the html file
try (PrintWriter writer = new PrintWriter("path/to/output.html")) {
writer.println(html);
}
System.out.println("HTML file generated successfully.");
}
}
In the above example, we use Printwriter to write HTML content into a file.Make sure the path is replaced with the path you want to save the html file.
Summarize:
This article answers common questions related to the Marked framework in the development of the Java library, and provides corresponding Java code examples.Using the Marked framework can easily analyze and convey the Markdown text, customize the analytical behavior, and convert the Markdown text into an HTML file.I hope this article can help you encounter when you use the MARKED framework in the development of the Java library.
