Allow configuration file to be extended

[blephy]

I,

It would be great to be able to extends a configuration file to another, like TSConfig or Eslint do, or at least to be able to write .cjs / .js configuration file to require another js file.

We use c8 in a mono-repo, and we cannot share a c8 configuration file between workspace:/

Thanks

This seems like a good feature request 👍

Do you need some help ?

@bcoe i did look to the c8 and yargs code. In fact, we can already extends configuration if the path to the extendable config is a json file.

This is already working :

{
  "extends": "../../config/c8/c8.config.json",
  // ...
}

What about making c8 compatible with yml and js configuration ? cosmiconfig sounds good for this.

Additionally, we should update the documentation. I did a branch but cannot push to this repository :/

Closing in favour of:

#431

With regards to cosmicconfig, I would prefer not to pull in a dependency for config management, if it can be avoided. I think it's not worth the complexity it would add to the library.

Additionally, we should update the documentation. I did a branch but cannot push to this repository :/

You will need to create a pull request form a fork, here's some documentation on how to do so 👍
