[salahoued]

I've come across this project by pure chance, after looking into the pywayland project, I was looking for a rusty fzf to replace the now dormant skim, it was happy surprise for me.

I can see that sweep offers good functionalities the like of which fzf has, but I couldn't get some to work for me, like the --preview option, I couldn't find the proper way for it to work. Is it like fzf: --preview 'bat {}' or is there any other way.

I tried to run the demo python -msweep demo, it didn't work

Traceback (most recent call last):
  File "<frozen runpy>", line 189, in _run_module_as_main

    class SweepSelect[I]:
                     ^
SyntaxError: invalid syntax

From this output I couldn't figure out the problem, is it some dependency missing?

I use opensuse Tumblweed and python-3.11

Thank for all your hard work, you've put into this utility
