# 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.
This library aims to make creating quick-and-dirty bots in Bash as easy
as possible. To create a basic bot, all you need is the following:
```
#!/bin/bash
source tg.sh
TELEGRAM_TOKEN=""
TELEGRAM_TOKEN="<token>"
function _on_msg() {
echo "${event[from_username]}: ${event[text]}"
if [[ "${event[text]}" == "o/" ]]; then
tg_send ${event[chat_id]} "\o"
tg_send ${event[chat_id]} "$(_escape '\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.
Please note how you need to *escape* the text if there are any characters
which would conflict with the MarkdownV2 standard. If you wish to use MD
styling, the `tg_send` call could look like that:
```
tg_send ${event[chat_id]} "[$(_escape "^_^")]($(_escape "https://example.org"))"
```
Alternatively, if you decide that you don't want to run `_escape` on every
string, set `ESCAPE_ALL` to `true` after loading the library.
