Examples of RSyntaxTextArea

org.fife.ui.rsyntaxtextarea.RSyntaxTextArea
An extension of RTextArea that adds syntax highlighting of certain programming languages to its list of features. Languages currently supported include:
- Assembler (X86)
- C
- C++
- CSS
- C#
- Delphi
- Fortran
- Groovy
- HTML
- Java
- JavaScript
- JSP
- Lisp
- Lua
- Make
- Perl
- PHP
- Ruby
- SAS
- Scala
- SQL
- Tcl
- UNIX shell scripts
- Windows batch
- XML files
Other added features include:
- Bracket matching
- Auto-indentation
- Copy as RTF
- Clickable hyperlinks (if the language scanner being used supports it)
- A pluggable "parser" system that can be used to implement syntax validation, spell checking, etc.
It is recommended that you use an instance of {@link org.fife.ui.rtextarea.RTextScrollPane} instead of a regularJScrollPane as this class allows you to add line numbers and bookmarks easily to your text area. @author Robert Futrell @version 1.3
