Incorrect error when using the --output-format=summary flag

[eitamal]

I think I found a bug! 🐛
(just a small one)

When invoking StyLua with the summary output format and without the check flag, e.g.

stylua --output-format=summary file.lua

I get an error:

error: --output-format=unified and --output-format=standard can only be used when --check is enabled

which, as you might have noticed, doesn't mention summary. So, I had a look at the code to see if I was missing something, and found this:

 // Check for incompatible options
    if !opt.check
        && matches!(
            opt.output_format,
            opt::OutputFormat::Unified | opt::OutputFormat::Summary
        )
    {
        bail!("--output-format=unified and --output-format=standard can only be used when --check is enabled");
    }

So it looks like either the check is missing standard and the error message is missing summary or the check should be checking standard instead of summary. But I don't know Rust, and I'm not sure what the expected behaviour should be - so I'm not sure how/what the fix would be.

Thanks!

Took me a while to figure out what the behaviour should be 😅, but looks like my intention was that --output-format=summary can only be used when --check is enabled (5840654).

So, I think the check is correct, but the error message is wrong. The error message should say --output-format=summary.

Ah that makes perfect sense - thanks for clarifying! Now that you mention it, having to use --check with the default output format (i.e. standard) doesn't seem quite right.

Anyway, I've made the PR (#949) if you want it and thank you for the quick response and for maintaining this awesome project! 🙂
