<h2>Why did I wrote it?</h2>
|
|
|
|
<p>Someday I found <code>guavad</code>, a disassembler for java byte
|
|
code (it does similar things like <code>javap -c</code>). I used
|
|
it on a class file, and found that it was possible to reconstruct the
|
|
original java code. First I did it by hand on some small routines,
|
|
but I soon realized that it was a rather stupid task, and that I could
|
|
write a <a href="dasm_to_java.perl"><code>perl</code> script</a>
|
|
that does the same. At the end of the next day I had a working
|
|
decompiler.</p>
|
|
|
|
<p>Now while it was working, it was not easy to use. You had to
|
|
decompile the code first with a disassembler, cut the method, you
|
|
wanted to decompile and then run the perl script on it. So I decided
|
|
to get some information of the class files and do this all
|
|
automatically. I decided to write it in <code>java</code> now,
|
|
because it suited best.</p>
|
|
|
|
<p>Just for the records: the java code is now more than 50 times
|
|
bigger than the original perl script and is still growing.</p>
