Where can I find a syntax highlighting library for Java?
提问by
I'm writing a source-code editor in Java (for Java source code), and I'd like to add simple syntax highlighting (distinctive coloring for keywords would suffice). Any suggestions?
我正在用 Java 编写源代码编辑器（用于 Java 源代码），我想添加简单的语法突出显示（关键字的独特着色就足够了）。有什么建议？

Something like JSyntaxPane, perhaps?
类似的东西JSyntaxPane，也许？
A very simple to use and extend JEditorKit that supports few languages. The main goal is to make it easy to have nice looking Java Swing Editors with support for Syntax Highlighting.

Might want to look at an existing editor (Notepad++ for example - http://notepad-plus.sourceforge.net/uk/site.htm) and see how user-defined syntax highlighting is done (oneo of the plugins to check - Gmod 10 Lua Syntax Highlighter). I'd wager that the Java (and other languages) are done similarly...
可能想查看现有的编辑器（例如 Notepad++ - http://notepad-plus.sourceforge.net/uk/site.htm）并查看如何完成用户定义的语法突出显示（要检查的插件之一 - Gmod 10 Lua 语法荧光笔）。我敢打赌 Java（和其他语言）的实现方式类似......

What about RSyntaxTextArea? It uses a modified BSD license.
RSyntaxTextArea怎么样？它使用修改后的 BSD 许可证。

You should check Google's prettify.jsout. Some pretty neat tricks in there, and you might get a more robust feel for syntax highlighting.
您应该查看 Google 的prettify.js。那里有一些非常巧妙的技巧，你可能会对语法高亮有更强大的感觉。

You first should think about using a common parser to create an AST (abstract syntax tree) from the sources. There are some tools around, first I find googling the internet was javaparser. It looks like this parser also records line numbers and columns, so the AST from javaparser can be a nice model for the editor.
您首先应该考虑使用通用解析器从源创建 AST（抽象语法树）。周围有一些工具，首先我发现谷歌搜索互联网是javaparser。看起来这个解析器也记录行号和列，所以来自 javaparser 的 AST 可以成为编辑器的一个很好的模型。
Just process the tree, define colors for the AST node types and print it.
只需处理树，为 AST 节点类型定义颜色并打印它。
