Check two IntelHex objects equality about intelhex

[diggit]

Using equality check over output of segments() seems to work.
My second question remains.

Due to internal data storage model there is no effective way for byte to byte comparison, that's actually O(n) operation.

[diggit]

By "effective way", I meant something what does not have to repack data and do other unnecessary operations. Preferably in __eq__. O(n) is fine and probably expected.

[bialix]

Unfortunately, internally it has to repack data for comparing.

[diggit]

I peeked into sources and IntelHex._buf seems like dict of address->data.
Equality comparison then would be just comparison of those dicts when taking account few other option (offset,...).
Am I wrong?

[bialix]

Yes, that's correct.

Sorry, it seems I haven't thought enough about your question. So basically all you need is to compare this._buf to other._buf.
Yep, that should be easy addition. Patches welcome, and please provide some tests.

Also, there is hexdiff.py script to compare two Intel Hex files, you might look into using it. Actually, no, sorry.
