Rye in webassembly (WASM)

Go-lang can also compile to webassembly (WASM). I was trying to make Rye compile to WASM with TinyGo for a while and this weekend I managed to produce a build. TinyGo is an alternative compiler that uses LLVM and should produce much smaller wasm packages. The compilation passed but I wasn't able to make the full interpreter work in a browser.

I could be wrong but it seems that a PEG parser library that I am using drastically increases the .wasm size (to 6MB) and compilation time to more than 45 minutes. I could be wrong. I will explore this option later but I decided not to take many more 45 minute tries. Consequent compilations can be much much faster, but if I remove and add the dependency it seems I am back to 40 minutes gone. Another option would be to rewrite a loader in a simpler PEG parser generator (not a "library"), but not this weekend.

So I tried the native Go WASM compilation and .wasm in my case was "just" 3MB (without the PEG parser I think it was 1MB). The compilation was immediate as usual in Go, and a very nice error message from Go in the browser console persuaded me to go this route for now.

The goal is not tothink Rye could be used instead of JavaScript in a browser environment, but it could be a Glue/Declarative component and I can think of many interesting experiments with Rye or even Spruce in the front-en.

Below is a minimal demo using a browser based code editor component Ace. It evaluates the code when I press Ctrl+X and displays the output and the result of the code below.

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...

Go's concurrency in a dynamic language Rye

The Rye programming language is a dynamic scripting language based on REBOL’s ideas, taking inspiration from the Factor language and Unix shell. Rye is written in Go and inherits Go’s concurrency capabilities, including goroutines and channels. Recently, Rye gained support for Go’s select and waitgroups. Building blocks Goroutines Goroutines are lightweight threads of execution that are managed by the Go/Rye runtime. They operate independently, allowing multiple tasks to run concurrently without blocking each other. Creating a Goroutine in Rye is straightforward. The go keyword is used to launch a new Goroutine, followed by the Rye function to be executed concurrently. For instance, the following code snippet creates and starts a Goroutine that prints a message after a delay: ; # Hello Goroutine print "Starting Goroutine" go does { ; does creates a function without arguments sleep 1000 print "Hello from Goroutine!" } print "Sleepi...
