Compressed File Editor

This is a tool can help you to dump and understand the compressed file format. It can help you to print the file structure to JSON.

How to Use

There are 5 executable files for deflate, gzip, zlib, lz4 and zstd compressed file.
Use following command to generate the structure JSON.

./deflate_dump <compressed_file>
./gzip_dump <compressed_file>
./zlib_dump <compressed_file>
./lz4_dump <compressed_file>
./zstd_dump <compressed_file>

How to Build

Linux

mkdir build
cd build
cmake ..
make

All the output files will be in output folder.

Windows

Use the Visual Studio as the compiler.

mkdir build
cd build
cmake ..

Then you can open the CompressedFileEditor.sln to edit and compile the code.

How to Debug

Linux

Use this command to generate the makefile to build with debug symbols:

cmake -DCMAKE_BUILD_TYPE=Debug ..

Then build the project.

Windows

Open the CompressedFileEditor.sln using Visual Studio and change the Solution Configurations to Debug. Rebuild the solution or only one project and start debugging.
