🎀 JANINOC(1) 🎀

okay bestie, welcome to the General Commands Manual section, and today we're talking about janinoc, a whole entire vibe 💅

✨ NAME ✨

Janino — a runtime Java Compiler. that's it. that's the name. iconic behaviour honestly 👑

🌸 SYNOPSIS 🌸

janinoc [options] source-file ...

like, options first, then as many source files as your little heart desires 💖

🦋 DESCRIPTION 🦋

So here's the tea ☕ — Janino is a compiler that reads a Java expression, a block, a class body, a source file, or a whole set of source files, and then generates Java bytecode that gets loaded and executed directly. no middleman, no waiting, just vibes ✨

Now listen: Janino is not meant to be a development tool. nope. it's an embedded compiler built for run-time compilation purposes — think expression evaluators, or "server pages" engines like JSP. that's its whole main character energy 💅

And janinoc? That's the front-end. it compiles all the input files you hand it. slay 🫶

💖 OPTIONS 💖

okay buckle up, here's every single flag, no cap:

  • -d output-dir — where to save your class files 🗂️
  • -sourcepath dirlist, -extdirs dirlist, -bootclasspath dirlist — where to look for other source files 🔍
  • -encoding encoding — the encoding of your source files, e.g. "UTF-8" or "ISO-8859-1" 🌈
  • -verbose — more output. yes, more. you asked for it 📢
  • -g [none|{lines,vars,source}] — generate all, none, or only some debugging info 🐛
  • `-warn:pattern-list — issue certain warnings. examples, bestie:
-warn:*        All warnings
-warn:IASF     Only warn against implicit access to static fields
-warn:*-IASF   Enables all warnings, except those against implicit access to static fields
-warn:*-IA*+IASF Enables all warnings, except those against implicit accesses, but do warn against implicit access to static fields

like the pattern matching is genuinely giving ✨

  • -rebuild — compile all source files, even if the class files seem up-to-date 👀 (they're lying to you, probably)
  • -help — prints a help message 🆘
