I believe it’s nushell trying to parse, not only the command line, but the files your typing on the command line, as you’re typing. i could be wrong though.

I just run into an issue that looks similar but unrelated to dev/stdin.

For me it happens when I target the file ~/.cargo/bin/nu_plugin_net like

register ~/.cargo/bin/nu_plugin_net

It hangs when I type the last character (t) and the character is not shown anymore.
When I start with

~/.cargo/bin/nu_plugin_net

and try to prepend it with register it hangs when I enter the r

It also hangs with

nu -c "register ~/.cargo/bin/nu_plugin_net"

but in this case <kbd>Ctrl</kbd>+<kbd>c</kbd> ends the command and I get the cursor back.

Most other plugins don’t cause this issue (nu_plugin_query, nu_plugin_gstat, nu_plugin_plist, nu_plugin_plot). register nu_plugin_from_parquet also hangs though.

Same behavior in Kitty and Gnome Terminal
