COQnow fails in tmux after upgrading to Fedora 39

[vincenzocaputo]

After upgrading to Fedora 39, coq_nvim cannot be started in tmux, as the following error is returned:

not enough values to unpack (expected 7, got 1)

    session,

I took a look at the worker.py and parse.py and I figured out that the issue stems from the splitting of the output of the systemd-run command:

https://github.com/ms-jpq/coq_nvim/blob/d4a58fa7ab20c928f88e416b3fcf6ada965bf314/coq/tmux/parse.py#L57-L67

Actually, the output of the command is something like this $0\037%0\0370\0370\037nvim\0370\037fedora, which cannot be splitted using \x1f as separator.

Workaround

I solved this issue, at least on my system, by encoding the command output to bytes using UTF-8, and then decoding it back into a Unicode string, as below

def cont() -> Iterator[Pane]:
    for line in decode(proc.stdout).encode('utf-8').decode('unicode_escape').strip().splitlines():
        (
            session,
            pane_id,
            session_name,
            window_index,
            window_name,
            pane_index,
            pane_title,
        ) = line.split(_SEP)

Having the same problem

For me it does not even start without tmux. I am using fedora 39. I get the same error:

@vincenzocaputo Thank you! I was having the same problem. Your workaround works for me.
