`Error: ⚠ Missing filename` on 5.2.0

Discussed in #209

On 5.1.0 and older, I could run e.g.

% watch -c -n 5 -t "sudo emlop p | tspin"
% journalctl -b -f -n 50 -u ssh | tspin

After updating to 5.2.0:

% tspin --version
tspin 5.2.0

these commands now give the following error instead:

Error:   ⚠ Missing filename (tspin --help for help)

tailspin/src/config/mod.rs

Line 47 in 2eafd02

#[error("Missing filename ({} for help)", "tspin --help".magenta())]

This still works fine:

% tail -f /path/to/file.ext | tspin

Not sure if this is a bug.

Thanks.

Hey @xfzv, thanks for letting me know about this. Definitely a bug.

I don't have the commands you linked (I'm on macOS), so I wasn't able to replicate it locally.

However, I suspect it is related to a change in how I was checking for data from stdin. I released a quick fix for it in 5.2.1. Did that fix the issue for you?

If not, do you know of other commands that can replicate this issue?

Can confirm 5.2.1 fixes the issue, thanks!
