Experimenting with code flow via GTK example

Piping and translating data from one point to the other is all fine and dandy, but I wanted to test solving messier and more statefull problems using Rye constructs.

One example of such code are GUI-s. I tried to write a simple GTK example in multiple ways, to see where it gets me.

Rye GTK binding uses generic functions. set-title, set-text, add-to ..., show are all words that dispatch on the kind of first argument and not ordinary "global" words.

First (top left) example uses an ordinary polish notation and "variables". It's very similar to something you could write in plain Rebol or some other function based language (otherwise, rebol has a well "known" GUI dialect)
Second (bottom left) uses variables and a lot of op-words. Words that take first argument from the left. This makes the structure look somewhat like it would look in a classical object oriented language. Like Python if you would add few parenthesis to the right spots.
Third relies less on variables and uses pipe-words to create 2 forward flows. But this also relies on the fact that set-* words return the object
Fourth uses injected block mechanism. It can support more inline computation and doesn't rely on set-* words returning the main object at all.

Fifth (bottom right) example uses some pipe-words in between. It has less symmetry and I IMHO worse than fourth example.

I've started writing an intro to the language not long ago ... I have partially written pages about op-words and pipe-words and I wrote a page about injected blocks today, so if you want to know more about these language features please look there.

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...
