Bots

There are two example projects available:

• Examples/hello-bot - a trivial bot which responds to /greet command.

• Examples/word-reverse-bot - demonstrates how to handle start and stop requests, keep session state and parse command arguments. Behaves differently in private and group chats. Uses a router and a controller.

TBD: an example using an SQLite database.

Building a bot

Let's build the second example.

git clone https://github.com/zmeyc/telegram-bot-swift.git
cd telegram-bot-swift/Examples/word-reverse-bot
swift build

If everything is correct, you will see:

Cloning /Users/user/Temp/telegram-bot-swift
Resolved version: 0.2.1
Cloning https://github.com/IBM-Swift/SwiftyJSON.git

Linking .build/debug/word-reverse-bot

Storing the token in source code is not a good idea, so there are two options of passing the token to bot:

Via environment variable:

Add the bot's token to ~/.profile:

export WORD_REVERSE_BOT_TOKEN="TOKEN"

Replace TOKEN with the token obtained from BotFather.

And reload the environment:

source ~/.profile

By storing the token in a file:

echo "TOKEN" > WORD_REVERSE_BOT_TOKEN

Run the bot

.build/debug/word-reverse-bot

Add your bot in Telegram, and play with it:
