Old thread: Lisp is the most powerful programming language.
What are you working on, Jow Forums?
/dpt/ - Daily Programming Thread

working through jonesforth and starting forth, so far it seems like every other interpreter that employs very trivial and very suboptimal solutions
planning find some real software implemented in forth to see how it's actually used, because juggling with top of stack to get basic arithmetic working is not amusing at all

Functional programming in GNU Make
### List operators

zip = $(if $2,$(call zip,$1,$(call slice,$2),$(call rotate,$3),$4 $(call $1,$(firstword $2),$(firstword $3))),$4)
### Arithmetic operators
inc = $(words $(call repl,$1,_) _)
max = $(words $(subst __,_,$(join $(call repl,$1,_),$(call repl,$2,_))))

You're pathetic, OP. Yes I'm pissed off that you didn't post Anime.
How else are we supposed to keep the tone of the thread and keep the less-desirables out?
Jack Bailey
Why do we feed people this lie of like "If you learn the basics of Java, in a month you can be a six figure salaried engineer."
Stop. Unless you're Dennis Ritchie himself you need a degree.
James Butler
Learn Lisp.

Henry Russell
There, there... Have a (you), poor soul thirsting for attention on anonymous basket weaving forum.
Lucas Cruz
I don't even know why I'm staying here anymore, there is no programming happening in these threads. Only retards arguing about retarded shit.
Andrew Cooper
why would you do this to yourself
Evan Murphy
>implying
Aaron Lewis
The unironic answer is that I wanted to demonstrate to Haskell fags how retarded they look by insisting on functional programming only and never anything else.
Sebastian Smith
you're here forever user, don't forget that
Henry Jenkins
but you're proving them right by demonstrating the power and flexibility of functional programming in something as goofy as GNU Make
Adam Watson
is that your idea of powerful
Levi Ramirez
i don't think it has the intended effect then
Alexander Nguyen
Can somone redpill me on why lisp is based
Bentley Green
I'm proving that functional programming can be done in any language, even one that doesn't have basic arithmetic operations, and that there's nothing inherently special about Haskell.
Gabriel Lewis
code as data
Jeremiah Collins
Haskell is special because of its type system and purity, that's kind of the whole point
John Richardson
Talking shit about programming is what this thread is for. If only because programming itself is shit.
Daniel Thomas
And what's impure about the code posted in ?
Brandon Wright
This. TDPT, or /dpt/ as it has become know as, was always intended as a containment thread back in the days when programming was discouraged on Jow Forums.
Brandon Barnes
What does that mean
Nolan Bell
It's easier to get attention from anime posting or bait than from working on actual projects. We probably keep going back here because anonymity is the only way to keep our sanity.
Easton Martin
Learning python after lisp here.
God damn it I already mix prefix notation and I am so fucking confused by some python design choices it's unreal. Urgh.
Thomas Wright
Haskell is designed to facilitate writing using FP style. And to be a playground for research (all this LANGUAGE directives).
Robert Sullivan
>a playground for research
cringing hard at this
Jaxson King
>a playground for research
Cringe aside, the literal only way to actually program in Make is by functional programming though.
David Watson
It means you can pass literal code into functions that can rewrite it.
Because I've conflated GHC and Haskell?
Josiah Cruz
Because it sounds like something only some computer scientist circlejerk would say.
Eli Gonzalez
Nothing, but afaik make allows for state, which is impure. it also doesnt have a type system.
Aaron Edwards
because people consider making shit programming languages "research"
Aaron Mitchell
Well, that is what people who write GHC say, so...
Jackson Sullivan
benchmarksgame-team.pages.debian.net
What's the point of FP if it's so slow? All you need is math and C.
Brayden Wood
it means the code can be passed around and manipulated like data
not limited to just lisp btw
Elijah Cooper
>Nothing, but afaik make allows for state
It doesn't, the only state it (usually) allows for is file modification timestamp.
>it also doesnt have a type system.
You can make one, just like you can make arithmetic operations.
Benjamin Brooks
>benchmarksgame

Easton Richardson
>I'm proving that functional programming can be done in any language
yeah well a homosexual and an institution already proved that in the 30s
>there's nothing inherently special about haskell
that's correct, no one claimed the opposite
although it is very _different_ from most other programming languages because of its type system, enforced purity and laziness.
Jordan Watson
You have to try and make shitty stuff before you could distill anything of value, though. Same applies to research.
Gavin Hernandez
>You can make one
so it doesn't have one...
I mean anyone can just make anything on top of any programming language
Eli Hall
>enforced purity and laziness.
These two are actually shared by Make, which is why it is a suitable comparison.
The type system is a fair argument though.
Henry Gray
Gabriel Nguyen
>I mean anyone can just make anything on top of any programming language
Isn't that the argument Haskellers use themselves though? That you can make anything by using the powerful typing system?
Jaxon Morris
>What's the point of FP if it's so slow?
To write correct and formal code, not to write fast code.
Aaron Gutierrez
>You have to try and make shitty stuff before you could distill anything of value
I disagree
I think you should try and make useful things first and start from there
You know, like every single other programming language people use
Kevin Evans
and sepples fags about their templates and (((lispers))) and pythonistas and typelets because muh reflection, etc.
Xavier Parker
make's type system can't be compared to Haskell though, that's a big difference
Ryder Hughes
what is your definition of correct
what is your definition of formal
Dominic Ward
>retard saw the haskell is useless video on his feed once
Wyatt Moore
Why common lisp is dead?
Alexander Long
Just because a particular implementation of a particular langiage in a particular case ends up being slower than another particular implementation of another particular language in that same case in no way implies FP has to be slow in princiole, because it has been formally proven not to be.
Liam Sullivan
are you an ESL? these are pretty basic words
Henry Nguyen
So, there's a new C++ standard coming out soon. And a bunch of others in regular use. Which one is the boss with the best weapon?
Ian Lopez
Should I learn Lisp if I hate Jews?
Zachary Johnson
linear types will save benchmarks
James Harris
Cope
Jason Bell
nope, i am curious what you believe these words mean in this context.
Connor Edwards
Well, yes. But Haskellers are exceptionally vocal about it, calling it stuff like "a playground for research" etc.
I don't disagree.
Mason Brooks
know your enemy
Christian Thompson
>functional programmer buttmad that even the author of the language admitted it was useless and just a prank to confuse brainlets
Samuel Lewis
You're more or less ok with anything from C++11 and beyond. The additions of 14 and 17 are straightforward to incorporate starting from 11.
Avoid older standards like the plague unless you absolutely have to (for example, having to work with legacy code).
Dominic Hughes
people develop it so i would not consider it dead
why would it matter anyway?
Christian White
It's not?
It's not as popular as say, java or python, but it certainly isn't dead. You'll probably have less package provided to program in common lisp but the language is so powerful you don't need those more often than not.
Don't be too scared, Lisp is still worthwhile to learn, it makes you smarter once you get it.
Christian Taylor
because that was the point of haskell, having a hackable implementation of a functional lazy programming language that researchers could "play" with.
Back in the time it was all about _lazy_ functional programming.
Hudson Brooks
Sold.
Jonathan Brown
why would a person's intuitive grasp of such basic regularly used words come in the form of a "belief" about the accuracy of a formal definition?
Ryder Taylor
yes, I'm so assblasted you could fit your mom in it
Adam Perez
That actually sounds sick, what other languages support this and how efficient is it when compiled?
Michael Lewis
Haskell is useful. I wrote a web-service in it ~ 5 years ago.
Jayden Edwards
so you can't answer a basic question, lol
what does it mean for FP code to be formal and correct
i'm looking for a rigorous answer here
Thomas Rodriguez
Computers are lost. We need to start over.
Lincoln Roberts
even more specific than that: it was about having a typed lazy functional language that could be run on normal hardware:
