  • 代码 format 能力。Express4Runner 类中提供一个 format 方法。支持代码 format，通用代码format实现
  • idea 高亮与语法提示插件。参考 idea Groovy console 功能，支持引用 classpath 中的类
  • 支持编译模式（参考 mvel，同时支持解释和编译模式），直接编译成 Java 字节码提升性能

Research direction
Investigate existing QLExpress CLI usage and design a REPL interface. For code formatting, review the referenced blog to understand the algorithm and adapt it to QLExpress's AST. For IDE plugin, study IntelliJ's plugin SDK and consider how to integrate with classpath. For compiled mode, research MVEL's compilation to bytecode and evaluate feasibility with QLExpress's expression parsing. Additionally, check existing QLExpress issues and PRs for prior work or discussions.
