I was styling my PS1-Prompt to resemble the iPython-Prompt as:

PS1FIRSTLINE="[n][t] [e[1me[38;5;196m]u@H[e[0m] in [e[1me[38;5;196m]w[e[0m"

PS1SECONDLINE="ne[92m]In [[e[1m]#[e[0m]] $ "

PS1="$PS1FIRSTLINE$PS1SECONDLINE"

However, sometimes i get weird issues like, that the beginning of the last executed command is still there after the prompt and can't be deleted.

I think that it's an issue with my way of escaping the colors with e[ ... ] and not something with bash or the suckless-terminal, that i'm using.

Can somebody help me out?

First see this answer of mine.

It's not immediately clear whether n should be considered printing or non-printing, or if the division is the same as printable vs. non-printable (like in the context of printable ASCII characters).

When it comes to PS1, however, I would say n should be called "printing" because it affects the size of the prompt and this is what matters here. You should put both occurrences of n outside of [ ].

The first n is explicitly inside [ ]. The second one (at the beginning of PS1SECONDLINE) looks like it's not at the first glance, but it is as well. There is an unmatched [ in PS1FIRSTLINE and when the whole PS1 is created the matching ] comes from PS1SECONDLINE.

These are your variables with proper modifications that put n outside of [ ]:

PS1FIRSTLINE="n[t] [e[1me[38;5;196m]u@H[e[0m] in [e[1me[38;5;196m]w[e[0m]"

#             ^^ deleted embracing [ ]                                    added closing ^^

PS1SECONDLINE="n[e[92m]In [[e[1m]#[e[0m]] $ "

#                ^^ added opening

PS1="$PS1FIRSTLINE$PS1SECONDLINE"
