Add a --show-config cli argument that prints the config.

Like --debug but it shows the config and exits right away?

[cpojer]

yes, a json-parseable config would be good. Maybe even this:

{
version: '…',
config: {…},
}

• adjusting jest-editor-support to use this new command.

Perfect, so I guess also testFramework right?

[cpojer]

Nah, nobody needs that. Can we make it so --debug also outputs its data as JSON the same way --show-config does (except without exiting)? The whole = is really weird.

Can I take one of these up? Seems like there are 2 issues here, one with the config to JSON, and the other for --debug? Maybe a separate issue for the --debug flag and I can take that on?

I'd like to get more involved. :)

@wyze sure, let me know if I can help with anything

The issue title mentions the argument as --show-config, but the convention of other arguments would make it --showConfig. Just wanted to throw that out there.
