Dear employee of BF Enterprise Solutions,

I hope this message finds you well. We're a long time and happy customer and have made frequent use of your service. The announcement of ed.bf was quite exciting for us as we could expand our UNIX toolset based on modern technology with more memory safety and portability.

Unfortunately, we have not been able to get bf.ed to work. We run a custom BF interpreter (for readability reasons) in our ecosystem and the developer we have can more easily share knowledge with the developer we have. If possible, we would like you to take a look at our interpreter and our Node-based environment (we're still working on migrating to AWS serverless of course) and see if there's anything we can improve on our end. Perhaps we have misread some implementation details that are necessary for full BF support.

Although we have a mature and battle-tested test harness of a whopping 7 unit tests (!!!), there's obviously room for risk and we are therefore reaching out.

The problem we have when running ed.bf is that it does print the Copyright statement as such:

ed.bf version 1.8.3-alpha

Copyright (C) 2021-2023 Artyom Bologov

ed.bf is provided as is, with absolutely no warranty, under the terms

TERMS-OF-SERVICE (only relevant for commercial use) for more
information.

We regret to inform you that after that point input is impossible and the program outputs nothing else. We have tested input in our system by testing simple cat-like programs like +[>,+.<], which fully worked as expected on keystroke. Also, line-by-line instead of character-by-character input was tested on ed.bf but that was not working however.

We have an open-source implementation at: https://github.com/Vaults/snippets/blob/master/src/brainfuckInterface.js

We excitedly await your response,
Vaults
