# telegram.sh, a telegram bot api library in bash
This library aims to make creating quick-and-dirty bots in Bash as easy as possible.
```
#!/bin/bash
source tg.sh
TELEGRAM_TOKEN=""
function _on_msg() {
echo "${event[from_username]}: ${event[text]}"
if [[ "${event[text]}" == "o/" ]]; then
tg_send ${event[chat_id]} "\o"
fi
}
tg_start
```
The above example is all you need to create a basic telegram bot.
The library is currently very WiP. Please proceed with caution.
