Hello!

This is the current Lemmy equivalent of https://www.reddit.com/r/ProgrammingLanguages/.

The content and rules are the same here as they are over there. Taken directly from the /r/ProgrammingLanguages overview:

This community is dedicated to the theory, design and implementation of programming languages.

Be nice to each other. Flame wars and rants are not welcomed. Please also put some effort into your post.

This isn't the right place to ask questions such as "What language should I use for X", "what language should I learn", and "what's your favorite language". Such questions should be posted in /c/learn_programming or /c/programming.

This is the right place for posts like the following:

"Check out this new language I've been working on!"
"Here's a blog post on how I implemented static type checking into this compiler"
"I want to write a compiler, where do I start?"
"How does the Java compiler work? How does it handle forward declarations/imports/targeting multiple platforms/?"
"How should I test my compiler? How are other compilers and interpreters like gcc, Java, and python tested?"
"What are the pros/cons of ?"
"Compare and contrast vs. "
"Confused about the semantics of this language"
"Proceedings from PLDI / OOPSLA / ICFP / "

See /r/ProgrammingLanguages for specific examples

Toit - a language for microcontrollers with live reloading (toitlang.org)

Some features:

Ruby-like syntax, terse lambdas that look like regular control statements.
Everything is an object.
Integrated package manager.

Jaguar is a small app that wirelessly connects to an ESP32 and can load and live-reload Toit programs. This is opposed to something like connecting the device via USB and re-installing the program every time you make a change.

Example (https://github.com/toitlang/toit/blob/master/examples/wifi/scan.toit, see the GitHub link for syntax highlighting):

// This example illustrates how to scan for WiFi access points.

import net.wifi

SCAN-CHANNELS := #[1, 2, 3, 4, 5, 6, 7]

main:
  access-points := wifi.scan
      SCAN-CHANNELS
      --period-per-channel-ms=120
  if access-points.size == 0:
    print "Scan done, but no APs found"
    return

  print """
      $(%-32s "SSID") $(%-18s "BSSID") \
      $(%-6s "RSSI") $(%-8s "Channel") \
      $(%-8s "Author")\n"""

  access-points.do: | ap/wifi.AccessPoint |
    print """
        $(%-32s ap.ssid) $(%-18s ap.bssid-name) \
        $(%-6s ap.rssi) $(%-8s ap.channel) \
        $(%-8s ap.authmode-name)"""
