#lfe — Public Fediverse posts

In this week's random excursion, I'm trying out Lisp Flavoured Erlang[^1], discovering all the good new-ish things that have been added to Erlang since the last time I played around with it. There is a `maybe` expression now[^2]! ☕

🎶 Who wants to live forever? - sang Freddie. Well… #science just said: not so fast. A @PNASNews study finds that life expectancy gains are slowing down across high-income countries. For generations born after 1939, the pace of improvement has dropped by nearly half:

:doi: https://doi.org/10.1073/pnas.2519179122

The reason? We’ve already reaped most of the benefits from reducing child mortality. So it’s no longer about living forever, but about living wisely.

Here's your regular reminder that #LFE is a very cool #Lisp (and a very cool #Erlang).

“they run on the BEAM, which also runs code written in #LFE (#Lisp Flavored Erlang)”

@jotaemei yeah, Erlang is a pretty good language. I have learned a little bit about it, although I don’t know enough about the OTP to really write any apps with it.

@ramin_hal9001 I have been a little interested in these ActivityHub-inplementing platforms written in Elixir, as they run on the BEAM, which also runs code written in #LFE (#Lisp Flavored Erlang).

AtomVM v0.6.0 is finally out: https://github.com/atomvm/AtomVM/releases/tag/v0.6.0

For who does't know it: #AtomVM allows to run #erlang, #elixir, #gleam and also #lfe on MCUs such as the #ESP32, the #RaspberryPi Pico (2040) and some #STM32, but it also supports Linux and wasm.

@mousebot Time to use pattern matching in #lfe :)

What a gem from @oubiwann in the LFE channel:

Macros are like Bebop.
Quoting Pat Metheny:
"What I look for in a musician is someone who has studied Bebop and can perform every note in any of the classic solos from that era, but never wants to play it again."

Learn and study macros. (Almost) never use them.

Metheny also said:
"What I look for in musicians is a sense of infinity".

So.... write macros that write macros? :)

The "Forward" to the #LFE Chinenual is now done too, again from the unpublished book "Introducing LFE": https://cnbbooks.github.io/lfe-manual/preface/forward.html

This should really be titled "what is a correct 'Hello World' program in a distributed language?" 😉

#erlang

Just added content to the #LFE "Chinenual" for the "About" section in Part I: https://cnbbooks.github.io/lfe-manual/part1/intro/about.html

Highlights include:
* What is LFE?
* (an extremely) Brief History of #Lisp
* Ditto for #Erlang
* What is LFE?

Code samples include not only LFE and Erlang, but also an M-expression, a Lisp 1.5 example, and a pre-Erlang #Parlog example :-)

Content is from an LFE book I was working on in 2015 that I eventually had to abandon. So happy it will be available now 😄

The one thing #LFE (Lisp flavoured Erlang) doesn't have is CLOS (the Common Lisp Object System). Of course not, since #LFE is not a Common Lisp. But it makes it harder to translate CL code to LFE.
Robert Virding has implemented a Lisp machine Flavours system for LFE, though :)

Don't get me wrong, Bordeaux Threads and all that stuff are cool.
But don't forget to take a look at the BEAM and its #Lisp flavour (#LFE) as well. I'd certainly be interested in your opinion on it.

What's so great about #LFE (Lisp Flavoured Erlang) is its compiled code is fully compatible with Erlang (and Elixir).
You could add LFE as a dependency to any Erlang project and continue to develop it in Lisp. (to make a point).

But why not just use #Erlang syntax, then? That's the wrong question: consider it an *offer* to developers more productive in a Lisp. And an *offer* to projects/problems that resemble Lisp-like systems but still need concurrency.
And macros.

@ShinNoNoir There are also #LFE (Lisp-Flavored Erlang) :lfe: and #Gleam, both are nice languages running on BEAM.

If you're interested in #LFE (Lisp Flavoured #Erlang) and how to use it in a mixed-with-Erlang approach, look through λMUD as an example:

Erlang/LFE interop is free lunch, basically.

Why would it be nice to program Liveviews in #LFE instead of #elixir?

Because it would be the
end
of the
end
end

of course, #LFE is the ideal distributed programming language, it just needs a major framework for people to deliver web apps with. if someone has a lot of time or some money that they want to turn into more money, investing in a framework that fully supports #phoenix + #liveview[1] in LFE could be the beginning of a #clojure-scale enterprise

[1] by giving your money to me ofc

I've lost a bit of touch with the #Lisp landscape. What are some new things happening?
#Coalton looks interesting: https://github.com/coalton-lang/coalton

#LFE has been here for a long time but overall is still the most exciting "new" Lisp to me.

@dottorblaster What 'productive' means is somewhat subjective. If the ecosystem & number of libraries is part of your productivity, #Elixir wins. If a Lisp makes you productive OTOH, #LFE. To me it's this and the seamless integration into Erlang that LFE gives you.
