TDLib vala

TDLib json interface (tdjson) for vala.

Using tdjson in vala

First you must build TDLib on your machine.

Then you need to link libtdjson.so shared library with your vala app/file.

Example

Here is an example code of using TDJson in vala:

public static void log_callback(int log_level, string message){
    print("LOG: "+ message);
}

void main () {
    // We need a client id (aka instance id) to deal with TDLib. 
    int client_id = TDJsonApi.create_client_id();

    //  Disable default TDLib log stream
    string setLogResult = TDJsonApi.execute("{\"@type\": \"setLogStream\", \"log_stream\": {\"@type\": \"logStreamEmpty\"}}");
    print(setLogResult);
    print("\n");

    //  Set log callback 
    TDJsonApi.set_log_message_callback(1024, (TDJsonApi.log_message_callback_ptr) log_callback);

    //  Set TDLib log verbosity level to 1023 (log everything)
    TDJsonApi.execute("{\"@type\": \"setLogVerbosityLevel\", \"new_verbosity_level\": 1023}");
    
    TDJsonApi.send(client_id, "{\"@type\": \"getOption\", \"name\": \"version\"");
    print(TDJsonApi.receive(10));
}

Build example

By default TDLib build instructions installs TDLib in td/tdlib.

Using valac:

• If TDLib is installed on your home directory:

  export TDLIB_PATH=$HOME/td/tdlib
  export LD_LIBRARY_PATH=$TDLIB_PATH/lib
  valac --vapidir . --pkg tdjson -X -L$LD_LIBRARY_PATH -X -ltdjson -X -I$TDLIB_PATH/include example.vala
  

• If TDLib is installed in /usr/local (recommended):

  valac --vapidir . --pkg tdjson -X -ltdjson example.vala
  

Run
