No support for int[][] (string[], etc.) function parameters. about solidity HOT 10 CLOSED

@aayarushin no, not yet in production. It is fully implemented, but pending review: #2863

The documentation has to be updated, yes.

Several reasons, but you are lucky, I'm working on exactly this right as I type (not exactly right but you get the point ;) )

from solidity.

    struct Patient {
        bytes32 name;
        uint weight; // weight is accumulated by delegation
        uint height;  // if true, that person already voted
        uint NHSNum;  //include timestamp
        bytes32 specialty;  
        bytes32 consultant;
        bytes32 diagnoses;
        uint Creatinite;
        uint Sodium;
        uint Potassium;
        uint eGFR;
        uint Urea;
    }
    Patient[] patients;

    function allPatients() constant returns(Patient[]) {
        return patients;
    }

without internal in allPatients() it will cause same error.
why such a basic feature not implement in?

unfortunately nested arrays aren't yet implemented as arguments for external functions.

also please implement structs

what's the status of this? function f (string[] _s) does not work, function f (address[] _a) does though.

@5chdn string is an array itself, so string[] is actually two-dimensional. The story is still pending, as can be seen from PT.

@chriseth Is passing and returning struct in functions in production yet? You have mentioned this in 0.4.17 release notes, but it is not clear if support is only for internal functions as the docs say or if this is also available between contracts and in function types? The doc: http://solidity.readthedocs.io/en/develop/frequently-asked-questions.html?highlight=struct%20function#can-a-contract-function-return-a-struct
Thank you so much for all work! :)

This explains why I get a Error: invalid solidity type!: tuple when I try to get back a struct
