JSyntaxPaneTTx

JSyntaxPaneTTx is a fork of JSyntaxPane, a syntax highlighting library built in Java.

Additional features in this fork include:

• Support extended from Java 6 through 14
• Customizable font size
• Additional language support (just the basics so far): Perl, Nasal
• Initially forked for use in the Text Trix editor but can be used independently in Java-based text editors for syntax highlighting

Compile

Dependencies

• JDK 6+ (mostly tested on 8-14)
• Maven

Build

Download this library and output a .jar file to the target folder:

git clone https://github.com/yoda-vid/jsyntaxpanettx.git
cd jsyntaxpanettx
mvn package

Alternatively, build from within Text Trix. Assuming that texttrix has been cloned already to a directory next to jsyntaxpanettx:

texttrix/build.sh --jsyn

Add Language Support

Support for additional languages can be added by creating new lexers and syntax kits for them. The simplest way to add this support is to copy an existing related language with a few updates:

• Copy a JFlex file from src/main/jflex/jsyntaxpane/lexers and name it with the language you're adding (eg copy c.flex to nas.flex)
• Update any reference to the language name in the .flex file
• Similarly, copy and update the corresponding Java file in src/main/java/jsyntaxpane/syntaxkits
• In src/main/resources/META-INF/services/jsyntaxpane:
  • Add a line in kitsfortypes.properties to include the new language lexer
  • Copy and update the corresponding syntaxkits/[lang]syntaxkit folder
• Rebuild JSyntaxPaneTTx
• Load your new syntax kit by specifying it with setContentType("text/[ext]");, where ext matches the extension name you gave in kitsfortypes.properties
