Reader of binary serialized Type Language Schema

This code has not been tested sufficiently. It's a rewritten version of original reader in C++. If you are going to use this for code generation, please do additional tests. Recheck my implementation for errors and so on.

The Type Language (TL) was invented many years ago. It was originally used in VK, and now in Telegram. The creators of this language invented and wrote all the necessary tools to work with it. For example, a parser of the language and its binary format for serialization was developed.

To work with TL Schemes using OOP. To generate the client MTProto code using official TL parsers and binary formats.

Many Open Source MTProto client use their own implementation of parsers, which are not ultimatum. They are hardcoded for their minimal task.

Hardcode is not the way of Telegram. Official Telegram's Open Source projects take the right approach. So, for example, tdlib generates several interfaces for different languages and this is how it looks:

Raw TL Schema -> Tl Parser -> binary TL Object -> TLO reader -> code generator.

pip install tlo

npm install tlo

You can find TLO files for tests here.

from tlo import read_tl_config_from_file, read_tl_config
# use read_tl_config(data) to pass bytes directly
config = read_tl_config_from_file('td_api.tlo')

const tlo = require('tlo');
//import {read_tl_config_from_file, read_tl_config} from 'tlo';
// use read_tl_config(data) to pass buffer directly
tlo.read_tl_config_from_file('./tlo_for_tests/telegram_api.tlo', (config) => {
    console.log(config);
});
