contract newNFT is NFTokenMetadata, Ownable {

constructor() {
nftName = "Synth NFT";
nftSymbol = "SYN";
}

function mint(address _to, uint256 _tokenId,
string calldata _uri) external onlyOwner {
super._mint(_to, _tokenId);
super._setTokenUri(_tokenId, _uri);
}

}

@treeder wdyt?
The downside is that it requires you to build a list of dependencies and explicitly mention all of them in the header (in theory we could scan every file for imports and try to resolve them)

[treeder]

Why can't we just let solc handle it?

[r-gochain]

@treeder because solc doesn't support that (only remix - they recommend using it) check this thread - #233 (comment)
