How to apply patterns?

[xyx0826]

I've just started with ImHex and have successfully created a pattern, but I couldn't figure out how to actually use this pattern on the data. I've looked everywhere in the menus and couldn't find a way to do that, while "Load pattern..." simply loaded the pattern data into the editor. It doesn't seem to be mentioned in the docs either. Would appreciate a pointer :)

Never mind! Sorry. Looked at #237 and got my answer:

After declaring a struct in the pattern, the struct has to be "instantiated" i.e. placed at an offset for ImHex to pick it up. I nailed the declaration but wasn't aware of the second part. This is what the solution looks like:

struct module_header {
    u32 magic;
    u32 version;
    // ...
};

module_header header @0x00;  // This is important!

I went looking for a placement button because I was in a different mindset.
