## Pattern Language

The Pattern Language is the completely custom programming language developed for ImHex.
It allows you to define structures and data types in a C-like syntax and then use them to parse and highlight a file's content.

- Source Code: [Link](https://github.com/WerWolv/PatternLanguage/)
- Documentation: [Link](https://docs.werwolv.net/pattern-language/)

## Database

For format patterns, libraries, magic and constant files, check out the [ImHex-Patterns](https://github.com/WerWolv/ImHex-Patterns) repository. 

**Feel free to PR your own files there as well!**

## Requirements

To use ImHex, the following minimal system requirements need to be met.

> [!IMPORTANT]
> ImHex requires a GPU with OpenGL 3.0 support in general.
> There are releases available (with the `-NoGPU` suffix) that are software rendered and don't require a GPU, however these can be a lot slower than the GPU accelerated versions.
> 
> If possible at all, make ImHex use the dedicated GPU on your system instead of the integrated one (especially Intel HD GPUs are known to cause issues).

- **OS**: 
  - **Windows**: Windows 7 or higher (Windows 10/11 recommended)
  - **macOS**: macOS 11 (Big Sur) or higher, 
  - **Linux**: "Modern" Linux. The following distributions have official releases available. Other distros are supported through the AppImage and Flatpak releases.
    - Ubuntu 22.04/23.04
    - Fedora 36/37
    - RHEL/AlmaLinux 9
    - Arch Linux
- **CPU**: x86_64 (64 Bit)
- **GPU**: OpenGL 3.0 or higher 
  - Intel HD drivers are really buggy and often cause graphic artifacts
  - In case you don't have a GPU available, there are software rendered releases available for Windows and macOS
- **RAM**: 256MB, more may be required for more complicated analysis
- **Storage**: 100MB

## Installing

Information on how to install ImHex can be found in the [Install](/INSTALL.md) guide

## Compiling

To compile ImHex on any platform, GCC (or Clang) is required with a version that supports C++23 or higher. 
On macOS, Clang is also required to compile some ObjC code.
All releases are being built using latest available GCC.

> [!NOTE]
> Many dependencies are bundled into the repository using submodules so make sure to clone it using the `--recurse-submodules` option.
> All dependencies that aren't bundled, can be installed using the dependency installer scripts found in the `/dist` folder.

For more information, check out the [Compiling](/dist/compiling) guide.
