Hey @punixcorn, thanks for working on a fix for the reported issue. I had the same problem with six and invalid escape sequence when I tried to load up gdb today. I cloned your fork, which allowed gdb-peda to launch, but I still had a few invalid escape sequence errors. I couldn't open an issue on your fork, so i thought I would just drop this here.

Taking your approach, I added r as a prefix to the strings in the four places indicated by the error. This seemed to fix it and no more errors on launch.

Thanks!

Hey @jimdiroffii , thanks for calling that out. I don't seem to have any more syntax errors on my end , but I will apply those changes to my fork. I am glad I was of help to you.

Hey @punixcorn, there seems to be a small typo in the README you are trying to merge, for debian it's python-six and not python-siz. Also, it looks like the package is python3-six

@CriimBow i saw these typos, i fixed and applied the changes to my fork but forgot about it here, i will fix that shortly, thanks for calling it out

i got this error and i don't know if i should make it raw string

@L42yH4d3s, yes you should.

        pattern = re.compile(r'|'.join(JMPCALL).replace(r' ', r'\ '))
