Standalone App

About

Helios is an all-in-one Java reverse engineering tool. It features integration with the latest up-to-date decompilers.

If you want to download the latest version, check out the CI server

There are several keybinds that can be used. To open a new file, simply use Ctrl-O. Arrow keys can be used to navigate the file tree. Enter or clicking a file will open that file into the editor view.

To open a different view, simply use Ctrl-T and a menu will pop up where the cursor is. You can use your arrow keys or your mouse to select a view.

If the file is a class file, you will be able to choose from a variety of decompilers and disassemblers. If the file is not a class file, you will only be able to view the hex representation and the plain text representation.

If you want to clear the GUI, you can use Ctrl-N to start a new session. This will reset all open views.

If you have modified a file that you are inspecting, you can use F5 to refresh the files. This will reload them from disk.

To close the current opened file, use Ctrl-W. To close the current opened view, use Ctrl-Shift-W

All files are stored inside the default temporary file directory on your OS. You can delete these files safely.

The settings file is located within the .helios folder inside your user directory. Inside the .helios folder you will find libraries which are not written in Java, but have been packaged with this program. You will also find the addons folder, where you can install new addons.

standalone-app's Issues

Hi I'm Fireflies

Repository

Dependence is missing from repository.

[ERROR] Failed to execute goal on project standalone-app: Could not resolve dependencies for project com.heliosdecompiler:standalone-app:jar:1.0.2: Could not find artifact com.heliosdecompiler:transformer-api:jar:2.0.3 in helios-decompiler-repo (https://repo.samczsun.com/repository/helios-decompiler/)

Failed to compile

I'm using the master branch, mvn package raises the following error,

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project helios: Fatal error compiling: invalid target release: 1.8 -> [Help 1]

Krakatau Assembler Suppert

Hi there,

I recently noticed that Krakatau isn't only an outstanding decompiler,
it also has a disassembler and a cooperating assember allowing you to edit
bytecode which is really nice to (for example) remove a malicious part of a programm
without having to deal with decompiling the whole project and recompile it (which often fails 😞 ). The bytecode-viewer already supports reassembling the krakatau output, but
I like Helios more in it's overall feeling so I ask you if you can integrate the Krakatau assembler 😃

Vinc0682 / VincBreaker

Be able to stop background tasks (if they do not seem to end)

As example just the procyon decompiler decided to stuck and now takes one cpu core fully.

An alternative would be to stop the decompilation process if a decompiler window was closed before the task finished.

Read settings.json file

I see in C:Users\<User>\.helios\settings.json are decompiler settings saved.
The file seems to be safed when helios shuts down, the content is updated.

However the settings are not honored at startup.

Tested with krakatau and cfr.

Enjarify version

I noticed you are using a commit hash for the Enjarify version. I thought I should point out that Enjarify follows semantic versioning now, in case you wanted to switch to that.

https://github.com/google/enjarify/releases

some tampered zip / jar files (which java can still read) are not registered as jar files in helios

instead its taken as binary file and hex is shown

CTRL-L Not Working

Hi,

On mac using the helios standalone jar file, when i select a .class file within a jar file and click CMD+T a dialog box comes up saying Search for: t instead of actually showing the decompiling options. Thanks.

Crash when MANIFEST.MF is tampered (jar still works)

https://github.com/ItzSomebody/StopDecompilingMyJava/blob/master/decompiler-tool-bugs/Entry-001/Entry.md

Handle AST

Perhaps there's a way to hook into CFR and Fernflower so there won't be a need for the parser

JARs not "unloaded"

Attempting to use the "Extract Strings" addon shows that a JAR is still loaded in memory after being removed from the tree view.

Reported just so I don't forget.

Similar to BytecodeViewer?

Currently you have no code or binaries published.
But it sounds a little bit like BytecodeViewer:
https://github.com/Konloch/bytecode-viewer

I think, that is something, which could be interesting for you.

Please update ASM so helios works with newer class files.

when decompiling with Procyon this seems to cause the window to be blank where there should be code

Why is a selected rt.jar location needed?

Do I see it right, that Helios wants, that the user select the location of rt.jar? Why?

It is in

System.getProperty("java.home") + System.getProperty("file.separator") + "lib" + System.getProperty("file.separator") + "rt.jar"

Uniquify open files in tab title

If simple class name is multiple times open, but in differnet packages, display part of the package of the class too in tab title.

Edit: Equal to intellij's approach.

Option to change keybinds and/or add GUI buttons as an alternative to the keyboard.

I need this program for a project I'm working on but I would prefer to have the option to change the keybinds into something I'm more used to. (I know I can just download and recompile it but I'm too lazy).

GUI buttons for all of the actions would be nice too.

Krakatau fails when libraries are used

Whenever you decompile something which depends on a library (in my case, it was a Bukkit plugin I had to recover source for), it will flip a table and throw an error because said class file is not found (as the classes are provided runtime)

An exception occured while performing this task. Please open a GitHub issue with the details below.

Procyon does not display synthetic methods but the flag is set it should.

This leads to totally empty classes only with some imports from procyon. Yes, I know there are other decompilers and Krakatau, the correct decompiler, but still it should be looked at.

Crash when zip contains invalid CRC

https://github.com/ItzSomebody/StopDecompilingMyJava/blob/master/decompiler-tool-bugs/Entry-010/Entry.md

Can't Open the Menu (to disass. or decompile)

Hi, I'm using latest Helios and Java version "1.8.0_141" but when I wanna open a different view, I can't. On previous versions I did it by pressing right-clic, but now nothing happens.... Plus, I've read the README file and "To open a different view, simply use Ctrl-T" but, neither works for me.

Which could be the problem? Thanks

Killing a background task fails.

I click the "X" button in the popup to kill the background task. The task doesnt die and neither does the dialog, but the "X" disappears. Thereafter the background task runs forever unless I restart Intellij. I find myself constantly having to restart intellij as a result.

Moving Enjarify to Rust

Hi, I am considering changing Enjarify from Python to Rust, which would require compiling a static binary. Do you think this is something you could handle? Any thoughts would be appreciated.

Add the jadx decompiler

Please add the jadx decompiler to the GUI, it is licensed under Apache 2 so there shouldn't be a problem at this point...

Switch to clicked on class if clicked on the sidebar

If a class is already open, it should switch to viewing that class when double clicked even if it is currently open instead of having to choose the class from the top bar.

Project inactive?

I see the commits, it did not update for almost 5 or 6 years. Does it inactive or dead?

Improve DecompileAndSaveTask

Ask for decompiler/disassembler to use.
Refer task to decompiler/disassembler impl class.
Decompile selected classes or whole jar file, taking advantage of, for example, fernflowers jar decompilation combined with the rename ambigious option.

Search and reload-functions.

First of all, I really love Helios and use it daily, so I was really happy once I saw the new GUI. However, there are two features that I'm missing: 😞

You cannot search within the decompiled / dissassembled file anymore.
You cannot reload files anymore. You have to create a new workspace and open the files manually.

I already put this on my to do list, so I surely will implement these features myself sometimes, but if someone with a better knowlege of the programm would like to implement these features, feel free 😄

Thanks in advance,
VincBreaker

Option to show a different view by default?

Would be nice if there was an option to set it to always see Text or Fernflower when you click on a file instead of always viewing the Hex :)

Got you another error which appears to be caused by one of your dependencies (but perhaps you could investigate it further - with a bit of luck it's fixable from Helios)

I vaguely remember the code used UTF-16 in their obfuscation, but I cannot find any sources for confirmation.
