When these tools come up, I like to post my little list of similar tools, for those interested. Apparently it's a hobby of mine: * fq - like jq for binary data: https://github.com/wader/fq * Kaitai Struct - https://kaitai.io/ * visualizer, for the above: https://github.com/kaitai-io/kaitai_struct_visualizer/ * HexFiend - a hex editor, but with "binary templates" feature : https://github.com/HexFiend/HexFiend * binary templates, for the above: https://github.com/HexFiend/HexFiend/blob/master/templates/T... * binspector - https://github.com/binspector/binspector * binary-parsing - a collection of links to similar such tools : https://github.com/dloss/binary-parsing * unblob - https://github.com/onekey-sec/unblob * ImHex - https://github.com/WerWolv/ImHex * GNU Poke - https://www.gnu.org/software/poke/ * dtrx - https://github.com/dtrx-py/dtr

x/ dtrx * feng - https://github.com/martinlindhe/feng ** they also have a similar list of prior art: https://github.com/martinlindhe/feng/blob/main/RESOURCES.md And some previous HN threads for similar such tools: * https://news.ycombinator.com/item?id=34434249 (unblob) * https://news.ycombinator.com/item?id=34986042 (GNU Poke #1) * https://news.ycombinator.com/item?id=36182873 (GNU Poke #2)

ImHex “A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.” I actually used it not too long ago to inspect why a mp4 file wasn’t valid. The pattern language that they have is quite nice and having sections of the hex highlighted and being able to see what structures they represent and what data was on those structures was very useful! https://github.com/WerWolv/ImHex
In Ask HN: What underrated open source project deserves more recognition?
I didn't use RemedyBG or Tracy, but I did try ImHex (https://github.com/WerWolv/ImHex) and it loaded 12% of the CPU because everything is being repainted 60 times per second. Heck, it even has an option to limit the FPS, which solves the CPU load a bit, but at the same time results in sluggish input because the event handling is tied to the drawing frequency. So yes, the experience was not good, and I don't see what these tools would lose by using a proper GUI. I don't want every utility to drain my laptop battery like a decent video game. ImGui is great if you already have a loop where everything is unconditionally redrawn every frame, but otherwise it's a really odd choice for an end-user application.
