A pure C# implementation of sproto. and using sprotodump compiler for C# language on your .sproto file to generate data access classes.
You write a Member.sproto file :
.Person {
name 0 : string
id 1 : integer
email 2 : string
.PhoneNumber {
number 0 : string
type 1 : integer
}
phone 3 : *PhoneNumber
}
.AddressBook {
person 0 : *Person
}
Then you compile it with sprotodump, to produce code in C#.
$ lua sprotodump.lua
usage: lua sprotodump.lua [[<out_option> <out>] ...] <option> <sproto_file ...>
out_option:
-d dump to speciffic dircetory
-o dump to speciffic file
-p set package name(only cSharp code use)
option:
-cs dump to cSharp code file
-spb dump to binary spb file
$
$ lua sprotodump.lua -cs Member.sproto -o Member.cs
Then you use that code like this:
AddressBook address = new AddressBook ();
address.person = new System.Collections.Generic.List<Person> ();
Person person = new Person ();
person.name = "Alice";
person.id = 10000;
person.phone = new System.Collections.Generic.List<Person.PhoneNumber> ();
Person.PhoneNumber num1 = new Person.PhoneNumber ();
num1.number = "123456789";
num1.type = 1;
person.phone.Add (num1);serialize and deserialize :
byte[] data = address.encode (); // encode to bytes
Sproto.SprotoStream stream = new SprotoStream (); // encode to stream
address.encode(stream);
Sproto.SprotoPack spack = new Sproto.SprotoPack ();
byte[] pack_data = spack.pack (data); // pack
byte[] unpack_data = spack.unpack(pack_data); // unpack
AddressBook obj = new AddressBook(unpack_data); // decodethe Test.sproto file:
Foobar 1 {
request {
what 0 : string
}
response {
ok 0 : boolean
}
}
dump to c# code:
public class Protocol : ProtocolBase {
public static Protocol Instance = new Protocol();
static Protocol() {
Protocol.SetProtocol<Foobar> (Foobar.Tag);
Protocol.SetRequest<SprotoType.Foobar.request> (Foobar.Tag);
Protocol.SetResponse<SprotoType.Foobar.response> (Foobar.Tag);
}
public class Foobar {
public const int Tag = 1;
}
}Read TestCaseRpc.cs for detail.
