telebot.nim

Async Telegram Bot API Client implement in @Nim-Lang

Notes

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

Installation

$ nimble install telebot

Usage

echo bot

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)

send local photo

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)
