 1 | # javap-vim
 2 | 
 3 | ## Overview
 4 | 
 5 | This small plugin calls the [`javap`](http://docs.oracle.com/javase/8/docs/technotes/tools/windows/javap.html)
 6 | tool on `.class` files opened in Vim, which allows you to read the decompiled bytecode of a JVM class file
 7 | instead of a useless binary representation of it. It works for files on the disk as well as inside zip/jar archives.
 8 | 
 9 | ## Prerequisites
10 | 
11 | You should have [Java](http://www.java.com) of any version installed, and `javap` must be accessible via your `PATH`.
12 | 
13 | ## Installation

15 | ### [Pathogen](https://github.com/tpope/vim-pathogen)
16 | 
17 |     $ git clone https://github.com/udalov/javap-vim ~/.vim/bundle/
18 | 
19 | ### [Vundle](https://github.com/gmarik/Vundle.vim)
