Thanks! This looks very similar to #89, looks like it doesn't handle options passed to tere, such as tere --version or tere --ignore-case, am I right?

I did not notice #89 before opening this - sorry! Yes, this currently doesn't handle any options, as nushell complains about flags if they don't appear in the subcommand signature. I'll look into it, thanks!

Hi this does not work for me, does anyone have a working config for using there in nushell? @Br1ght0ne

We made some language changes to Nushell, and it should be possible to use def --wrapped --env to achieve both options passing and preserving the directory after cd.

Cool! Feel free to update the PR to include these. Maybe it's also good to mention that version > x.y.z is required, like it is saying for Xonsh currently.

I updated the README with some info on how the shell alias should work: https://github.com/mgunyho/tere#testing-a-new-shell-integration

Thanks for the heads up @kubouch! I'll try it out in the coming days.
