FFDec Build Tool

Decompiles .swf files using FFDec, and processes the output to make it more readable.

What does it do?

Pre-processing

• Convert line endings to LF
• Remove trailing whitespace
• Remove more than one empty line
• Add a newline at the end of the file
• Remove empty lines between interface function declarations
• Remove empty lines between class field declarations with same modifiers

Post-processing

• Recover function parameters based on function body (for setters and constructors)
• Recover function return type based on function signature (manual)

Usage

wget https://github.com/jindrapetrik/jpexs-decompiler/releases/download/version22.0.2/ffdec_22.0.2.zip
unzip ffdec_22.0.2.zip -d ffdec_22.0.2

cargo build --release

RUST_LOG=info ./target/release/build-tool decompile <file.swf> --output tree/file/ --ffdec ffdec_22.0.2/ffdec.jar
RUST_LOG=info ./target/release/build-tool preprocess tree/file/
# Now you can create a Git repository in the output directory and do an initial commit
# to make sure post-processing won't break anything

RUST_LOG=info ./target/release/build-tool postprocess tree/file/
# Now do another commit
