Hi @dave-tucker thanks for your efforts and good finding for new use case. Comment inline.

This allows for multiple license-eye configurations to be contained

within the same .licenserc.yaml file. The intended use is for a project

that has multiple packages or modules with differing licenses.

This is a perfect example to have multiple sections for header config while it's weird to allow multiple sections for the entire .licenserc.yaml content as stated below.

For header commands, the behaviour is to always evaluate every config

section in the config file. This was chosen since it seems convenient to

have a single command for checking all licenses in CI.

For deps commands, the --config-index flag is used to select a config,

with 0 (first) being default. This was chosen since deps can generate

a LICENSE file, which could not be valid should the license differ

between configurations.

Yes but --config-index doesn't help in that case where the project has different licenses per module. All dependencies' licenses should be included no matter which module introduces them so there is no need to have multiple dependency config sections. And the license of the project itself is complex so users should not use {{.LicenseContent}} in the template, instead they should compose the license content in LICENSE template themselves stating clearly which module is licensed under what license.

So my opinion is to allow both object (HeaderConfig) and array ([]HeaderConfig) for header config, object is to make it simple for users who doesn't have the case here and to be compatible for existing users (we have many users out there already and I don't want to break their CI), and array is to address the case you have. So the following two configs are both valid ( 1st is the same as existing format and 2nd is newly added )

header:
  content: ...
  paths: ...
  # ...
dependency: # the same as before 

header:
  - content: ...
    paths: pkg1
    # ...
  - content: ...
    paths: pkg2
    # ...
dependency: # the same as before

Comments addressed and PR updated. I'm not sure it's possible to express in YAML "this field could be a dictionary, or a sequence" so instead I opted to change Config -> ConfigV1, add a new ConfigV2 and then use an interface Config to ensure the two types are used can be used interchangeably. V2 is tried first, with a fallback to V1.

Hi, CI fails, please fix them first.

Sorry about that. I had an out-of-date golangci-lint version which made make lint throw lots of spurious errors.
Upgrading to v1.43.0 didn't work out either - hit panics with go-critic.
Eventually I had to use the golangci-lint docker image, so hopefully this should pass now 😓

Thanks! I will take another look soon.

@dave-tucker Friendly ping.

Sorry for the delay. Review comments addressed.

Thank you @dave-tucker , can you by the way share which repository will use this feature smile ?
