WHY NO REVIEW YET
TopGit writes full reviews for the most-starred, most-requested repositories. This page is a snapshot until then — see the READ ME tab for the original README in full.
Open Source Flash SWF decompiler and editor. Extract resources, convert SWF to FLA, edit ActionScript, replace images, sounds, texts and fonts. Various output formats available. Works with Java on Windows, Linux and macOS.
Application description and features
For information about using the software, list of features, etc., visit FFDec Wiki.
Free-Decompiler.com website
In the past (before 2018), we were using free-decompiler.com domain as homepage and GitHub for the source code, We've now moved all information (except the issue tracker) to GitHub.
Download application
For downloading the app, see latest release.
Older versions and nightly builds are available at the releases section
How to install
See installation section of the wiki
Source code
How to get the source
You can make a local copy of the sources with the following command:
This assumes you have git installed on your system.
Branches
Git source control manager supports multiple code branches. We use two main branches.
master - for released "stable" versions
dev - for newest changes from developers - "nightly" version is released from this branch
You can switch to dev branch with following git command:
git checkout dev
GIT recommended
It is recommended to have GIT commandline executables installed. Building script uses GIT to include revision number into the binary. (For Windows, you must enable Git in windows command line during installation.)
Netbeans project
Source code contains Netbeans Project so you can open it in Netbeans IDE. Then you can use standard actions like Run, Build, Debug, Clean and Build in the IDE. Other specific tasks can be executed via menu on build.xml (see Ant part)
Ant
If you do not have Netbeans, you can build source code also with Apache Ant.
After installing Ant it is good to put it into your PATH variable.
Open up commandline and navigate to sources directory.
To run application, execute task "run" by entering this command:
ant run
To only build, execute build task:
ant build
Building libraries
There are few libraries which need to be built too. These libraries are placed in "libsrc" directory.
FFDec_lib - core of decompilation, SWF parsing, exporting
This library is built automatically with main project, but can be build also separately with its own Ant script.
jpacker - used for compression of JavaScript Canvas scripts (Netbeans/Ant project)
jpproxy - proxy part of FFDec (Netbeans/Ant project)
LZMA - used for SWF compression (Netbeans/Ant project)
nellymoser - used for Nelly Moser sounds decoding (Netbeans/Ant project)
Swf2Exe - Stub for "Save to EXE" feature (Delphi 7 Project)
ttf - used for TTF font export (Netbeans/Ant project)
gnujpdf - used for PDF export (Netbeans/Ant project)
Docker
We have Dockerfile for headless running for not needing to install Java or FFDec locally.
(Original script by Mahdi Lazraq)
Build
docker build -t ffdec .
Usage
FFDec CLI is the entrypoint, so you can pass arguments directly:
docker run --rm -v ./input:/work/input -v ./output:/work/output ffdec [args]
Change log
All notable changes are listed in the file CHANGELOG.md
Deployment
Nightly builds
When a commit is pushed/merged into dev branch, a new prerelease version is created automatically by GitHub actions CI.
These prerelease versions are called nightly builds. On releasing a new nightly build, the previous nightly build is removed.
Stable versions
A new stable version is created automatically by the GitHub Actions CI when merging dev branch into master.
To such version a tag is added in format versionx.y.z.
Contributing
Please read CONTRIBUTING.md for details on our code of conduct, and the process for submitting pull requests to us.
Versioning
Versions are in format x.y.z, for example 9.1.2.
For the versions available, see the tags on this repository.
We try to use semantic versioning.
Nightly builds have additional suffix _nightlyN where N is number which increments with every (automatic) nightly release
and does not depend on the x.y.z numbers. (This means nightly number is NOT reset to 0 when releasing stable)
Older nightly builds are NOT available through git tags.
Authors
The decompiler was originally written by Jindra Petřík also known as JPEXS.
The application was made in Czech Republic.
