Ka-Pi

A JVM Bytecode Manipulation Framework inspired by ASM.

Ka-Pi, known as coffee pronounced in Min Nan, which has multiple usages and an indispensable place in not only modern society, but also computer science.

Features

Ka-Pi offers several essential modules relates to JVM ecosystem:

• cfsp - A general purpose class file parser that transform class file into nodes described in The Java® Virtual Machine Specification Java SE 20 Edition

Basic usages

Parse class file into structural nodes

To parse a class file using cfsp, you'll need to enable feature cfsp first:

toml ka_pi = { version = "...", features = ["cfsp"] }

Then, you'll be able to use class file parser in your own project:

```no_run

use std::fs::File;

use cfsp::parse::{to_class, ParsingOption};

fn main() {

let mut file = File::open("Main.class").unwrap(); let class = toclass(&mut file, ParsingOption::default().parseattribute()).unwrap();

println!("{:?}", class);

}

```

See also

There are other related jvm projects developed by me may help the production of JVM projects along with Ka-Pi: - frape - A direct interop bridge between Rust and Java reflection library in low communication cost. (No releases yet.) - jars - A simple jar extraction library.
