Talking in Rye over Telegram

Telegram is a popular messaging app that offers a variety of solid clients and features, including chatbots. In this blog post, we will explore how to create a Telegram chatbot that we can communicate with, in Rye language - yeah, we’re fans :=).

Starting with an Echo Bot

Our first step in creating a Telegram chatbot will be to create a simple Echo bot. An Echo bot simply echoes back whatever message it receives. This is a good starting point for learning how to create more complex bots.

Setting up a new bot in Telegram involves interacting with the BotFather on Telegram itself to get a token, which you’ll save in a .token file.

Rye uses Go’s telegram-bot-api library quite direct. With a few helper functions the example code could be shorter and more high level, but this better shows us what is going on behind the scenes.

So we load the API token, create an instance of the Telegram-bot and define its on-update method. In it we parse the ‘Message’ out of the JSON message we received, and Chat ID out of that. We need ID to create a reply message, with Text the same as it was in the incoming message. And we send it.

Less variables, more flows example vs Python

In the last blogpost ( Less variables, more flows ) I wrote a quick practical script I needed. It was an uncommon combination of CGI, two GET requests with Cookies and a POST request with Authorization header. I really like practical random/dirty problems, rather than ideal - made up problems to test the language. To get a sense of comparison I rewrote the example 2 times while removing specific Rye features. But that comparison is meaningless to a person that doesn't know Rye or at least Rebol already. So I went on fiverr and made a request for a Python script with these requirements. I got a nicely written Python script that uses functions for each step. To be more comparable, I rewrote the Rye code to a similar structure. Below is the result ... For a next step, it would be interesting, to extract a little simpler example out and add error handling. With Rye-s specific failure handling, I think the difference would become even greater. You can find Rye on github .

Ryelang - controlled file serving example and comparison to Python

This is as anecdotal as it gets, but basic HTTP serving functions in Rye seem to be working quite OK. They do directly use the extremely solid Go 's HTTP functions, so that should be somewhat expected. I made a ryelang.org web-server with few lines of Rye code 3 months ago and the process was running ever since and served more than 30.000 pages. If not else, it seems there are no inherent memory leaks in Rye interpreter. Those would probably show up in a 3 month long running process? And now I got another simple project. I needed to make a HTTP API for some mobile app. API should accept a key, and return / download a binary file in response if the key is correct. Otherwise it should return a HTTP error. So I strapped in and created Rye code below. I think I only needed to add generic methods stat and size? , all other were already implemented, which is a good sign. Of course, we are in an age of ChatGPT, so I used it to generate the equivalent Python code. It used the ele...

Receiving emails with Go's smtpd and Rye

This goes a while back. At some project for user support, we needed to receive emails and save them to appropriate databases. The best option back in the day seemed project Lamson . And it worked well ever since. It was written in Python by then quite known programmer Zed Shaw. It worked like a Python based SMTP server, that called your handlers when emails arrived. It was sort of Ruby on Rails for email. We were using this ever since. Now our system needs to be improved, there are still some emails or attachments that don't get parsed correctly. That isn't the problem of Lamson, but of our code that parses the emails. But Lamson development has been passive for more than 10 years. And I am already moving smaller utilities to Rye. Rye uses Go, and Go has this nice library smtpd , which seems like made for this task. I integrated it and parsemail into Rye and tested it in the Rye console first. Interesting function here is enter-console , that can put you into Rye console any...
