Java Markdown Generator

Simple to use Java library to generate beautiful markdown.

Usage

Integration

Gradle

You can get snapshot and release builds from JitPack:

repositories {
    maven { url 'https://jitpack.io' }
}
dependencies {
    compile 'com.github.Steppschuh:Java-Markdown-Generator:master-SNAPSHOT'
}

Alternatively, release builds are also available on Bintray:

repositories {
    maven { url 'http://dl.bintray.com/steppschuh/Markdown-Generator' }
}
dependencies {
    compile 'net.steppschuh.markdowngenerator:markdowngenerator:1.3.2'
}

Maven

<dependency>
  <groupId>net.steppschuh.markdowngenerator</groupId>
  <artifactId>markdowngenerator</artifactId>
  <version>1.3.2</version>
</dependency>

JAR

You can download the latest .jar files from GitHub or Bintray.

Examples

Most Markdown elements have static convenience methods in the Markdown class. You can also use their repesctive constructors, as shown below.

Emphasis

@Test
public void example() throws Exception {
    StringBuilder sb = new StringBuilder()
            .append(new Text("I am normal")).append("\n")
            .append(new BoldText("I am bold")).append("\n")
            .append(new ItalicText("I am italic")).append("\n")
            .append(new StrikeThroughText("I am strike-through"));

    System.out.println(sb);
}

Output:

I am normal
**I am bold**
_I am italic_
~~I am strike-through~~

Headings

@Test
public void example() throws Exception {
    StringBuilder sb = new StringBuilder()
            .append(new Heading("Heading with level 1", 1)).append("\n")
            .append(new Heading("Heading with level 2", 2)).append("\n")
            .append(new Heading("Heading with level 3", 3)).append("\n")
            .append(new Heading("Heading with level 4", 4)).append("\n")
            .append(new Heading("Heading with level 5", 5)).append("\n")
            .append(new Heading("Heading with level 6", 6));

    System.out.println(sb);
}

Output:

Heading with level 1
====================
Heading with level 2
--------------------
### Heading with level 3
#### Heading with level 4
##### Heading with level 5
###### Heading with level 6

Rules

@Test
public void example() throws Exception {
    System.out.println(new HorizontalRule());
    System.out.println(new HorizontalRule(20, HorizontalRule.ASTERISK));
}

Output:

---
********************

Images

@Test
public void example() throws Exception {
    String text = "I am an image";
    String url = "https://dummyimage.com/300";
    System.out.println(new Image(text, url));
}

Output:

![I am an image](https://dummyimage.com/300)

Lists

@Test
public void example() throws Exception {
    List<Object> items = Arrays.asList(
            "Items can be anything",
            new Date(0),
            1337
    );
    System.out.println(new UnorderedList<>(items));
}

Output:

- Items can be anything
- Thu Jan 01 01:00:00 CET 1970
- 1337

Tasks

@Test
public void example() throws Exception {
    List<TaskListItem> items = Arrays.asList(
            new TaskListItem("Task 1", true),
            new TaskListItem("Task 2", false),
            new TaskListItem("Task 3")
    );
    System.out.println(new TaskList(items));
}

Output:

- [x] Task 1
- [ ] Task 2
- [ ] Task 3

Tables

@Test
public void example() throws Exception {
    Table.Builder tableBuilder = new Table.Builder()
            .withAlignments(Table.ALIGN_RIGHT, Table.ALIGN_LEFT)
            .withRowLimit(7)
            .addRow("Index", "Boolean");

    for (int i = 1; i <= 20; i++) {
        tableBuilder.addRow(i, Math.random() > 0.5);
    }

    System.out.println(tableBuilder.build());
}

Output:

| Index | Boolean |
| -----:| ------- |
|     1 | false   |
|     2 | true    |
|     3 | false   |
| ~~~~~ | ~~~~~~~ |
|    18 | false   |
|    19 | true    |
|    20 | false   |

Code

@Test
public void example() throws Exception {
    String code = "// notice this new line\n" +
            "System.out.println(\"Hello\");";
    System.out.println(new CodeBlock(code, "Java"));
}

Output:

    ```Java
    // notice this new line
    System.out.println("Hello");
