Commands

erc7730 lint

The lint command runs validations on descriptors and outputs warnings and errors to the console:

$ erc7730 lint registry
checking registry/lido/calldata-stETH.json...

checking registry/lido/calldata-wstETH.json...

checking registry/makerdao/eip712-permit-DAI.json...
DEBUG: Optional Display field missing: Display field for path `nonce` is missing for message Permit. If intentionally excluded, please add
it to `exclude` list to avoid this warning.
WARNING: Missing Display field: Display field for path `owner` is missing for message Permit. If intentionally excluded, please add it to
`exclude` list to avoid this warning.

It can be called with single files or directories, in which case all descriptors will be checked.
