Async Telegram Bot API Client implement in @Nim-Lang
From version 1.0.0, procs likes newMessage, newPhoto,.. are gone, use sendMessage, sendDocument instead.
If you still prefer the old/ugly way to send stuffs, just import telebot/compat for backward compatible
$ nimble install telebot
import telebot, asyncdispatch, logging, options, strutils
var L = newConsoleLogger(fmtStr="$levelname, [$time] ")
addHandler(L)
# remember to strip your secret key to avoid HTTP error
const API_KEY = strip(slurp("secret.key"))
proc updateHandler(b: Telebot, u: Update): Future[bool] {.async.} =
if u.message.isNil:
# return true will make bot stop process other callbacks
return true
var response = u.message
if response.text.len > 0:
let text = response.text
discard await b.sendMessage(response.chat.id, text, parseMode = "markdown", disableNotification = true, replyParameters = ReplyParameters(messageId: response.messageId))
let bot = newTeleBot(API_KEY)
bot.onUpdate(updateHandler)
bot.poll(timeout=300)
import telebot, asyncdispatch, options, logging, strutils
# remember to strip your secret key to avoid HTTP error
const API_KEY = strip(slurp("secret.key"))
proc updateHandler(bot: TeleBot, update: Update): Future[bool] {.async.} =
discard await bot.sendPhoto(response.chat.id, "file:///path/to/photo.jpg")
let bot = newTeleBot(API_KEY)
bot.onUpdate(updateHandler)
bot.poll(timeout=300)For more information please refer to official Telegram Bot API page
