subcommand `config` exits with error

[Korbinian Maier]

Describe the bug

Running cargo spellcheck config --stdout throws an error:

Error:
   0: Failed to convert to toml
   1: values must be emitted before tables

Location:
   src/config/mod.rs:145

The error messages hints that there is something wrong with the config struct. I'll investigate further which part is responsible.

To Reproduce

Steps to reproduce the behaviour:

1. checkout master
2. Run cargo spellcheck config --stdout (or --user)
3. Spellcheck fails with an error

Expected behavior

Prints default config on stdout.

Screenshots

Please complete the following information:

• System: Arch linux
• Obtained: cargo
• Version: current master, git bisect shows that the error was introduced in either 94dcfa8 or 6b9d09f (the latter one doesn't compile with rust-1.54 on my machine)

Additional context

Here is the output of running with high verbosity. Backtrace does not contain much information, so I skipped it.

Backtrace omitted.
Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.

Since I can't reproduce it, could you run with RUST_BACKTRACE=full?

[Korbinian Maier]

Weird that everything worked fine on your side.. for me it was also broken on Ubuntu 20.04 with rust 1.54 and 1.56..

[Bernhard Schuster]

I think I mixed up two issues, so I could reproduce it.
