nakilon / befunge98

[WIP] The first Befunge-98 interpreter in Ruby (abandoned in favour of RASEL)

I code since 1994.
I'm skilled in Ruby and A.I.
I can solve unsolvable.

Here are some of my

• most successfull and handy projects:
  • IDHash -- the most accurate and fast perceptual image fingerprinting algorithm and Ruby gem
  • nakischema -- object validation with the simplest syntax
  • lineprofiler -- Ruby statistical flat profiler
  • PCBR -- ranking algorithm, usable for non-heuristic optimization, agnostic to data distribution shape
  • p5rb -- Ruby DSL for p5.js
• most fun projects:
  • RASEL -- esoteric programming language
  • utility chat bots (Slack, Telegram, IRC, Twitch, Trovo, etc.)
    one of them could learn to talk on the fly, another one is currently used by multiple Twitch streamers
  • converted S.T.A.L.K.E.R. game assets to NPC/artifacts/etc. maps
  • procedurally generated CS:GO map
  • visual web page structure recognition proof-of-concept
• other projects:
  • Shelenium -- a tool to automate or test terminal UIs, such as made with curses
  • directlink -- CLI to convert arbitrary webpage URL to direct images links

A GitHub stars list of tools and libraries I use.

Sometimes I contribute to popular gems and SDKs with bugfixes or documentation improvements.
In spare time I translated ruby-lang.org to Russian.
I can make slides and give a talk.

If you are a recruiter, here is my CV in English (updated Mar 2023).
And recently I started a little cringe blog with notes about coding.

befunge98's Issues

GUI

Hi,

I realize you asked me some questions on the Glimmer Gitter to build a GUI for Befunge without getting satisfactory answers to all your questions.

Glimmer DSL for Tk was too young to use anyways since it was at version 0.0.5 at the time as an early experimental proof-of-concept alpha only. I just resumed development on it recently, but it is still far from being complete or ready for production use.

That said, a new Glimmer GUI library has sprung up recently that you might find good enough for your needs as it is feature-complete:

Glimmer DSL for LibUI

Just like Glimmer DSL for Tk, this library runs in MRI CRuby (meaning its apps start instantly and have a low memory footprint), but it additionally includes its own binary libraries, so you do not have to pre-install any prerequisites to use it (assuming you are on an x64 machine)

In any case, I did answer all your questions on Glimmer Gitter regarding Glimmer DSL for SWT. You should be able to build what you need (Befunge) in it. Regarding that grid display glitch, it is a bug in SWT, but the solution for it was to simply preset a window shell width/height or force a resize on the window after display. By the way, I've built a programming language GUI in Glimmer DSL for SWT before: Draw Color Repeat, so I know for sure you can do the same.

If you have any further questions, I would be more than happy to help. I can support you completely in building a GUI with Glimmer DSL for LibUI or Glimmer DSL for SWT (sorry, I was unavailable before as I was out of town for several months).
