@schnedan Das freut mich. Dann verwendest du vermutlich nicht #ImHex.

Went looking for a hex editor the other day, found ImHex.
#ImHex is pretty cool. It's a tool for:
- Hex editing (highlighting! :D)
- Data analysis
- File format exploration
But kind of a memory hog. Maybe a leak somewhere.

Do you know that a single binary profile can contain two distinct profiles? In this example we can see that a single profile called "name" has a so-called hat profile called "name//hat" that is in the same binary file, ready to be loaded into the Linux kernel.

#AppArmor #ImHex

I've added support to see capabilities allowed by a given binary #AppArmor profile to my apparmor-binary project.

#ImHex is pretty sexy, especially the colored-by-file-format-patterns feature 😍

I'm currently experimenting with "colordiff" for the video-md5 case...

The pattern system in #ImHex is incredible! Very cool stuff ❤️

I reached the stage where I feel this can be shared with (probably very few) interested parties.

Head to https://gitlab.com/zygoon/apparmor-binary and load the result into #imHex

You will also need an #AppArmor binary profile, compiled with apparmor_parser and saved to disk.

I'm making progress writing #ImHex pattern language describing compiled apparmor profiles.

Some lessons:
- never auto-evaluate patterns
- save your pattern text before evaluating to a separate editor
- crash recovery can crash (especially on "\x)
- typing "\x crashes a lot but not always - I paste that whenever I need
- namespaces seem to crash like all the time. I stopped using them.

I'm writing #ImHex pattern language to load and display compiled #AppArmor profiles.

So far the language is excellent but ImHex is crashing very often, so I do bulk of the editing in gedit and paste it around.

Ah, nice, ImHex has a pretty sweet xmas update...

So, I made my first stupidly simple ImHex pattern file for parsing ttyrec files. Go me.

God #imhex is beautiful

#ImHex est toujours le meilleur éditeur hexa éxistant.

Wiiii! Colors! #ext4 #imhex

Does anyone have experiences with reverse engineering binary formats and can suggest a good tool for it?
I'm currently working with #ImHex, but while the pattern language seems like a big step in the right direction, it seems to be more suited to describing and parsing already known formats, and leaves things to be desired for a more explorative approach.
It also doesn't seem to consider the pattern part of the project, and doesn't remind me to save it. Lost me a bit of work yesterday :/

Today's shenanigans: playing with emacs calc, trying to get org-roam to do what I want, and fiddling with imhex, which seems like a nice hex editor and maybe could replace 010 for me.

#emacs
#imhex

First, working on a file pattern for #ImHex, so I can have a better idea of what I'm working with. I'm pretty happy with the progress I've made so far, considering I've never made a pattern before.
