On a related topic, there's this program, not an editor but a binary explorer, which looks somehow relevant to reverse engineering: https://hachoir.readthedocs.io/ https://hachoir.readthedocs.io/ The principe seems very good, like a wireshark for binary files. Not sure how powerful it is in practice. It can browse the hierarchy behind a binary format, down to individual fields (even bits). API offers edition capabilities. It has graphical (wx) and textmode (python-urwid) interfaces. Hachoir is able to open invalid / truncated files. Here are the available commands: hachoir-grep hachoir-metadata hachoir-metadata-csv hachoir-metadata-gtk hachoir-metadata-qt hachoir-strip hachoir-subfile hachoir-urwid hachoir-wx
