dasTelegram

Telegram Bot API bindings for daslang.

Zero-DOM JSON pipeline — uses sprint_json for requests and sscan_json for responses. No read_json/from_JV overhead.

Requirements

• daslang with dasHV module enabled (DAS_HV_DISABLED=OFF)
• sscan_json / sprint_json builtins (daslang >= 0.5)

Install

daspkg install github.com/borisbat/dasTelegram

Or clone manually into your project's modules/dasTelegram/.

Usage

options gen2
options rtti
options persistent_heap

require telegram/tbot
require fio

[export]
def main() {
    var token = ""
    unsafe {
        token = get_env_variable("TELEGRAM_BOT_TOKEN")
    }
    telegram_set_configuration(configuration(token = token))

    // get bot info
    var me <- telegram_getMe()
    print("Bot: {me.username}\n")

    // echo bot loop
    var offset = 0l
    while (true) {
        var updates <- telegram_getUpdates(get_updates(offset = offset, timeout = 30l))
        for (u in updates) {
            offset = u.update_id + 1l
            if (u.message != null) {
                unsafe {
                    let msg & = *u.message
                    if (!empty(msg.text)) {
                        telegram_sendMessage(send_message(chat_id = "{msg.chat.id}", text = msg.text))
                    }
                }
            }
        }
    }
}
