# telegram.sh, a telegram bot api library in bash # 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 #!/bin/bash
source tg.sh source tg.sh
TELEGRAM_TOKEN="" TELEGRAM_TOKEN="<token>"
function _on_msg() { function _on_msg() {
echo "${event[from_username]}: ${event[text]}" echo "${event[from_username]}: ${event[text]}"
if [[ "${event[text]}" == "o/" ]]; then if [[ "${event[text]}" == "o/" ]]; then
tg_send ${event[chat_id]} "\o" tg_send ${event[chat_id]} "$(_escape '\o')"
fi fi
} }
tg_start tg_start
``` ```
The above example is all you need to create a basic telegram bot. Please note how you need to *escape* the text if there are any characters
The library is currently very WiP. Please proceed with caution. 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.
