• This is a C# rewrite of https://github.com/AElfProject/contract-plugin/blob/master/src/contract_csharp_generator_helpers.h#L37
• Also includes a basic unit-test

This expected output doesn't seem right. We need to fix either the code or the test case.

[aeshanw-aelf]

yeah I think ill fix the code (y). the spaces are too big.

[aeshanw-aelf]

I've removed the redundant line-breaks + extra-spaces. so the output comments look more compact. lemme know ur thoughts. thx!

[gldeng]

URL is wrong.

URL is wrong.

These are not file level comments. Is this output correct? It makes no sense to print out the comments for methods and messages like this.

[aeshanw-aelf]

hmm these comments are present in the file tho i suppose it would be best to just print the top-level file-proto comments? i.e just // These are test header comments! based on the example below. wdyt?

syntax = "proto3";
// These are test header comments!
import "aelf/options.proto";
import "google/protobuf/empty.proto";
import "google/protobuf/wrappers.proto";
// The namespace of this class
option csharp_namespace = "AElf.Contracts.HelloWorld";

service HelloWorld {
    // The name of the state class the smart contract is going to use to access blockchain state
    option (aelf.csharp_state) = "AElf.Contracts.HelloWorld.HelloWorldState";

    // Actions (methods that modify contract state)
    // Stores the value in contract state
    rpc Update (google.protobuf.StringValue) returns (google.protobuf.Empty) {
    }

    // Views (methods that don't modify contract state)
    // Get the value stored from contract state
    rpc Read (google.protobuf.Empty) returns (google.protobuf.StringValue) {
        option (aelf.is_view) = true;
    }
}

// An event that will be emitted from contract method call
message UpdatedMessage {
    option (aelf.is_event) = true;
    string value = 1;
}
