AnsiScape

AnsiScape is a simple Java library that allows the user to format the output of the applications using ANSI Escape Codes.

Library is available in jcenter().

gradle:

repositories {
    jcenter()
}

dependencies {
    compile 'net.andreinc.ansiscape:ansiscape:0.0.2'
}

maven:

<repositories>
    <repository>
        <id>jcenter</id>
        <url>https://jcenter.bintray.com/</url>
    </repository>
</repositories>
<dependency>
  <groupId>net.andreinc.ansiscape</groupId>
  <artifactId>ansiscape</artifactId>
  <version>0.0.2</version>
</dependency>

Example (1)

AnsiScape asciiScape = new AnsiScape();

String formatted = asciiScape.format("{b Some Bold Text {u Also Underlined}}");
String formatted2 = asciiScape.format("Romanian Flag {redBg    }{yellowBg    }{blueBg    }");

System.out.println(formatted);
System.out.println(formatted2);

The output:

Example (2)

In this example we are defining our own escape codes classes (in a way similar to CSS classes):

AnsiScapeContext context = new AnsiScapeContext();

// Create new escape classes that can be used as tags inside the text
AnsiClass title = AnsiClass.withName("title").add(AnsiSequence.BOLD);
AnsiClass url = AnsiClass.withName("url").add(AnsiSequence.UNDERLINE, AnsiSequence.BLUE);
AnsiClass text = AnsiClass.withName("text").add(AnsiSequence.RED);

context.add(title).add(url).add(text);

AnsiScape ansiScape = new AnsiScape(context);

String format = ansiScape.format("{title Bold title}\n" +
                                                 "-{text Some url: {url www.google.com}};\n" +
                                                 "-{text Some other url: {url {redBg www.redbackground.com}}}");

System.out.println(format);

The output:

Supported classes

By default the following escape classes can be used:

Escape Class	Description
{b }	Bold text

{dim }	Dim text
{u }	Underlined text
{underline }	Underlined text
{blink }	Blink text
{reverse }	Reverse text
{blank }	Blank
{overstrike }	Overstrike text
{reset }	Resets everything inside tag
{black }	Black foreground
{blackBg }	Black background
{red }	Red foreground
{redBg }	Red foreground
{green }	Green foreground
{greenBg }	Green background
{yellow }	Yellow foreground
{yellowBg }	Yellow background
{blue }	Blue foreground
{blueBg }	Blue background
{magenta }	Magenta foreground
{magentaBg }	Magenta background
{cyan }	Cyan foreground
{cyanBg }	Cyan background
{white }	White foreground
{whiteBg }	White background

Notes

• Library woks well with Linux and Mac terminals. It wasn't tested on Windows, but as far as I know it won't work on Windows XP or older cmd.exe terminals without additional hacks ;
• In this stage the library is experimental - there are no unit tests for the moment;
• Some terminals (like IntelliJ Output Console) do not implement all the ascii codes.
