• ImHex now automatically writes all log output to a file
• Added menu items to save and load data processors
• Added support for copying values from the pattern language console
• Added RISC-V, M68K, M680X, WebAssembly, MOS65XX and BPF architectures to disassembler

Improvements

  • This means, to use built-in functions you now need to download and use libstd from the content store and include the correct include file

Environment values, in/out variables and improvements

Changelog

Additions

• Added global progress bar to show currently running tasks
  • This shows all currently running background tasks in one places
  • With this, also a bunch of things that previously were running synchronously have now been made asynchronous.
• Added link to Discord server to Welcome screen
• If another ImHex instance is already open on Windows, new files are now automatically opened in that current instance.
  • It's still possible to have multiple instances running. Just open a new instance without opening a file through it.
• Added ability to clear the recent files list. Thanks to @draftshade

Pattern Language

• Added a Environment Variables tab to pattern editor view
  • Environment variables let you specify a value (string, boolean, integer or float). These values can then be accessed again through the use of std::env.
• Added in/out variables
  • in variables work similar to properties found in e.g Unity. They automatically add an entry with their name to the UI and can be set to some value through the UI. The value will be applied before running the pattern.
  • out variables work the same but simply display whatever value has been assigned to them once the pattern is done running.
• Dangerous functions such as file IO or HTTP request functions are now gated behind a user confirmation dialog.
  • The first time such a function gets called in the current session, a popup will show up asking the user to confirm or deny running the pattern. The user can then either allow all dangerous function for this session or deny it in which case the popup will show up again the next time the function is called. When denying, execution of the current pattern is aborted.
• Added break and continue statements
  • These can be used inside of for and while loops but also inside of structs. When an array is created and a break statement is hit, the array will stop growing and keep its current size. When a continue statement is hit, the current entry will be skipped but the array continues to grow until it reaches the end.

Improvements

• Added better timeouts for all curl code.
  • If you don't have an internet connection, ImHex will no longer try to check for updates for ages
• The diff view line spacing is now is the same as the one in the main hex editor view
• Improved how shortcuts are handled within ImHex

Bug Fixes

• Fixed opening files as read-only if user doesn't have write permissions
• Fixed Windows TTY COM Port view
• Fixed restarting of ImHex on Linux Thanks to @qxxxb
• Fixed saving files
• Fixed reading data from huge files
• Fixed pattern language [[color]] attribute not working for arrays and structs
• Fixed IPS patches import and export

GDB and Raw disk provider

Changelog

Additions

• Added GDB Server data provider
  • This allows accessing memory data from running processes, microcontrollers and many other things. ImHex can attach to any running GDB Server over the network
• Added Raw Disk data provider
  • This allows accessing raw disk images or partitions of devices connected to your computer
• Pattern Language: Added std::env function and a configuration menu for it
  • This lets you query strings, integers, bools and floats from a list and use them within the script making configuring patterns much easier.
• Added "File -> Save Pattern..." option to save the current pattern language code

Improvements

• Added selection size in hexadecimal to hex editor view
• Redid data provider reading and writing. This should fix many issues with non-zero base addresses or large files with multiple pages
• ImHex now uses the native API to open websites so the command line window doesn't pop up every time you're clicking on a link
• Improved about and settings page
• Added icon to footer when ImHex is being run with Administrator or root permissions

Bug Fixes

• Pattern Language: Fixed variable access inside of pointer pattern yielding invalid results

• Fixed cursor not changing to the right resize arrow in the window corners

Rendering issues

If you're on Windows and you're experiencing any rendering or your Computer's or VM's GPU doesn't support OpenGL, download the opengl32.dll file from the releases below and drop it next to the ImHex application. This will cause the entire UI to be software rendered which will be much heavier on your CPU but may allow you to use ImHex at least.

Plugin Development

If you'd like to build a plugin for ImHex, you can do so now easily using the C++ and Rust plugin templates found here:

• C++ Template
• Rust Template

ImHex is no longer completely unusable everywhere

Documentation

A new documentation for ImHex (mainly the pattern language right now) is in the works and can be found here: https://imhex.werwolv.net/docs. It is a lot more detailed than the one found on the Wiki here and contains information about all the new features as well. Check it out!

Changelog

Bug Fixes

  • This caused the window to be unmovable and unresizable on platforms other than Windows
• Fixed crash on Windows when launching ImHex without a terminal window on Windows

I am so sorry for this mess...
