Pattern Language

The custom C-like Pattern Language developed and used by ImHex is easy to read, understand and learn. A guide with all features of the langauge can be found in the wiki or a simpler version in ImHex under Help -> Pattern Language Cheat Sheet

Additional Files

For format patterns, includable libraries and magic files, check out the ImHex-Patterns repository. Feel free to PR your own files there as well!

Nightly builds

See latest nightly builds on the artifacts result of the Build action here.

NOTE: We currently only provide nightly builds for macOS (x86_64)

Compiling

You need a C++20 compatible compiler such as GCC 10.2.0 to compile ImHex. Moreover, the following dependencies are needed for compiling ImHex:

  • GLFW3
  • libmagic, libgnurx, libtre, libintl, libiconv
  • libcrypto
  • capstone
  • nlohmann json
  • Python3
  • freetype2
  • Brew (macOS only)

Windows and Linux

Find all-in-one dependency installation scripts for Arch Linux, Fedora, Debian/Ubuntu and/or MSYS2 in dist.

After all the dependencies are installed, run the following commands to build ImHex:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j

To create a standalone zipfile on Windows, get the Python standard library (e.g. from https://github.com/python/cpython/tree/master/Lib) and place the files and folders in lib/python3.8 next to your built executable. Don’t forget to also copy the libpython3.8.dll and libwinpthread-1.dll from your mingw setup next to the executable.

On both Windows and Linux:

  • Copy the files from python_libs in the lib folder next to your built executable.
  • Place your magic databases in the magic folder next to your built executable
  • Place your patterns in the pattern folder next to your built executable
  • Place your include pattern files in the include folder next to your built executable

macOS

To build ImHex on macOS, run the following commands:

brew bundle --no-lock --file dist/Brewfile
mkdir build
cd build
CC=$(brew --prefix llvm)/bin/clang CXX=$(brew --prefix llvm)/bin/clang++ PKG_CONFIG_PATH="$(brew --prefix openssl)/lib/pkgconfig":"$(brew --prefix)/lib/pkgconfig" cmake -DCMAKE_BUILD_TYPE=Release ..
make -j
