I guess its aimed to people who already misuse them

#

I'm looking at it with the wrong mindset

Hello my esoteric children

sick hound Sep 28, 2018, 6:43 PM

#

an esoteric bytecode-ish language

#

b'\1\4\0\0\4\3\1\2' is a cat program

#

every operator has one operand except for 5 which has two

#

0 outputs the operand as an ascii character
1 jumps to the operand (starting from 0)
2 does nothing
3 deletes the first 128 bytes of the program and is the only way to jump to parts of the program more than 255 bytes
4 takes input (one character) and writes it to the program at the operand (starting from 0)
5 writes the second operand to the first (starting from 0)

#

the program's only memory is the program itself, with only 256 addressable bytes

#

the cat program writes its input to the operand of the output instruction and then executes the output instruction

my first contribution on gitlab is an esoteric language :)

cunning wave Sep 28, 2018, 7:02 PM

#

the current challenge is an esoteric language?

frosty wyvern Sep 28, 2018, 7:03 PM

#

Yes

#

But it doesnt have to be esoteric

#

Just read the challenge : )

Task: Create and(or) implement an esoteric language of your own!

frosty wyvern Sep 28, 2018, 7:09 PM

#

But yeah, the task is about esoteric languages but some people like @vague gust actually created an almost real normal language

vague gust Sep 28, 2018, 7:11 PM

#

I haven't added quite a few crucial things yet but hey it sorta works

#

and I will submit a MR soon

cunning wave Sep 28, 2018, 7:13 PM

class KInterpreter:
    stack = []
    def eval(self, code):
        for char in code.split("k?")[1:]:
            if char == "+":
                self.stack.append(self.stack.pop() + self.stack.pop())
            elif char == "-":
                self.stack.append(self.stack.pop() - self.stack.pop())
            else:
                self.stack.append(ord(char))

good enough? @frosty wyvern

#

esoteric enough?

vague gust Sep 28, 2018, 7:14 PM

#

huh nice

#

that is rancid

#

good esoteric

cunning wave Sep 28, 2018, 7:14 PM

yeah

vague gust Sep 28, 2018, 7:19 PM

how do you say hello world in your language

cunning wave Sep 28, 2018, 7:19 PM

#

i dont

#

lol

vague gust Sep 28, 2018, 7:20 PM

#

see with sef we can do

#

def main() do
    print("Hello world!")
end

cunning wave Sep 28, 2018, 7:20 PM

i came up with this in like 2 minutes joseph

vague gust Sep 28, 2018, 7:20 PM

what a beauty

frosty wyvern Sep 28, 2018, 7:27 PM

#

k

#

my language has the nicest syntax

pure dew Sep 28, 2018, 7:28 PM

#

not quite so esoteric if you swap k? for spaces

#

@frosty wyvern nah tbh i think mine does

frosty wyvern Sep 28, 2018, 7:28 PM

#

oh you have the weird lispy thing right

pure dew Sep 28, 2018, 7:28 PM

#

lisp? its lambda calculus

#

it is pretty similar tho

frosty wyvern Sep 28, 2018, 7:29 PM

#

oh its just pure lambda calculus

#

show

#

: )

pure dew Sep 28, 2018, 7:29 PM

#

no its applied lambda calculus

frosty wyvern Sep 28, 2018, 7:29 PM

#

so haskell

#

javascript

pure dew Sep 28, 2018, 7:30 PM

#

uh

#

pure lc doesnt have numbers or any kind of operators

frosty wyvern Sep 28, 2018, 7:31 PM

#

i didnt mean pure in any formal sense

pure dew Sep 28, 2018, 7:31 PM

#

applied adds + - * /, numbers, logical operators, and the ability to bind abstractions to names

#

oh

#

yea, its just lambda calculus

frosty wyvern Sep 28, 2018, 7:32 PM

#

sweet

#

did you submit it yet

pure dew Sep 28, 2018, 7:32 PM

#

lolno

frosty wyvern Sep 28, 2018, 7:32 PM

#

:(

pure dew Sep 28, 2018, 7:32 PM

#

ill show an example when i fix the alpha reducer

#

i got beta reduction done and realized i didnt do alpha reduction correctly

#

i posted this earlier

#

py-lci> λabcdef.(a b) (c d) (e f)

frosty wyvern Sep 28, 2018, 7:35 PM

#

oh god

#

it's beautiful

fallen heath Sep 28, 2018, 7:35 PM

#

I guess that makes sense tbh

#

It takes in garbage, randomises it and outputs garbage

frosty wyvern Sep 28, 2018, 7:36 PM

#

LOOOL

pure dew Sep 28, 2018, 7:36 PM

#

uh

frosty wyvern Sep 28, 2018, 7:36 PM

#

oof

pure dew Sep 28, 2018, 7:36 PM

#

that is offensive

frosty wyvern Sep 28, 2018, 7:36 PM

#

lmaooo

pure dew Sep 28, 2018, 7:36 PM

#

its left associative

fallen heath Sep 28, 2018, 7:37 PM

#

In my language all values go in a double ended queue that only accepts unique values and for execution of functions parameters are taken from alternating ends of the queue

frosty wyvern Sep 28, 2018, 7:39 PM

#

I wanna make a new language already

#

Though if I ever do make another language

#

I'll write a formal grammar

#

and probably look into that python yacc binding or whatever

pure dew Sep 28, 2018, 7:40 PM

#

nono

frosty wyvern Sep 28, 2018, 7:40 PM

#

and also use proper ASTs or whatever

pure dew Sep 28, 2018, 7:40 PM

#

use Lark

frosty wyvern Sep 28, 2018, 7:40 PM

#

my interpreter is absolutely crap hacked together

pure dew Sep 28, 2018, 7:40 PM

#

its fast

fallen heath Sep 28, 2018, 7:40 PM

#

I really dislike yaccs style

#

You define variables in the files namespace and then yacc finds those and uses them

cunning wave Sep 28, 2018, 7:42 PM

#

hmmm

#

i should do jumps

#

yeah

pure dew Sep 28, 2018, 7:43 PM

#

Lark (using LALR) is the fastest and lightest on memory out of many common python grammar parser libraries

frosty wyvern Sep 28, 2018, 7:45 PM

#

Perhaps next I should just work on implementing a very simple language "VM" runtime

#

with bytecode

#

instead of bothering writing grammars and parsing an actual language

#

frig it

#

people can write bytecode

cunning wave Sep 28, 2018, 7:46 PM

#

should a language be able to edit its own opcodes at runtime?

#

it should?

#

right?

frosty wyvern Sep 28, 2018, 7:46 PM

#

Uh

#

I mean

#

it doesnt have to

#

what do you mean exactly

cunning wave Sep 28, 2018, 7:47 PM

#

well atm i have a list of opcodes

#

an now i can jump around that list

#

so in theory i could have an opcode deleting opcodes from the list

frosty wyvern Sep 28, 2018, 7:47 PM

#

Yeah, I mean I guess that falls into like.. metaprogramming

#

where the program modifies itself

pure dew Sep 28, 2018, 7:48 PM

#

metaprogramming is good

#

@cunning wave do it

aight @pure dew self modifying code working whats next

pure dew Sep 28, 2018, 9:15 PM

#

@cunning wave speculative self modification

cunning wave Sep 28, 2018, 9:15 PM

#

huh?

pure dew Sep 28, 2018, 9:22 PM

#

is easiest with bytecode

#

Speculative execution is the normal term

#

For every condional or jump, predict the result of the conditional or the location of the jump

fallen heath Sep 28, 2018, 9:25 PM

#

Ah, introduce spectre into your language

cunning wave Sep 28, 2018, 9:25 PM

#

there are no conditional jumps yet though

#

there are just jmps

pure dew Sep 28, 2018, 9:26 PM

#

start executing (in a new thread maybe) the instructions as a result of that condtional or at that jump. If the actual cond/jump doesnt equal the predicted one, toss out the computed result or kill the thread

#

then add conditional jumps

#

@cunning wave or just randomly decide whether to execute a random instruction every cycle

cunning wave Sep 28, 2018, 9:29 PM

#

that feels like it could break the program pretty easily

pure dew Sep 28, 2018, 9:29 PM

#

it may execute the given one, or it'll pull an instruction outta its ass

#

it could

cunning wave Sep 28, 2018, 9:31 PM

#

ok

#

skni can do conditional jumps now

pure dew Sep 28, 2018, 9:32 PM

#

skni?

cunning wave Sep 28, 2018, 9:32 PM

#

skip next if

pure dew Sep 28, 2018, 9:32 PM

#

uh lol

cunning wave Sep 28, 2018, 9:32 PM

#

it pops a value from the stack and if its not 0 skips the next instruction

pure dew Sep 28, 2018, 9:32 PM

#

does that do what it sounds like it does?

hm?

pure dew Sep 28, 2018, 10:00 PM

#

"asd".split() will yield "asd"

#

it splits on spaces

cunning wave Sep 28, 2018, 10:01 PM

#

first
itll return ["asd"]
2nd if i pass a custom string to it itll split on that custom string

#

oh you mean that input split

#

its meant to do
a b c d e f g

pure dew Sep 28, 2018, 10:01 PM

well, ye, it returns a list

yknow?

pure dew Sep 28, 2018, 10:01 PM

but if they enter a b cd e f by mistake, itll crash

huh that's pretty neat

also lmao I forgot I could have just used a list to find the operand

gonna look at em in a sec

brisk zenith Sep 29, 2018, 8:41 PM

as you can see there, i actually call the unbound magic methods for int there (cause importing operator is too mainstream)

@brisk zenith now turn it into an expression

brisk zenith Sep 29, 2018, 8:51 PM

#

4

#

let's just hope the answer is always 4.

pure dew Sep 29, 2018, 8:52 PM

#

a lambda is technically an expression, is it not? So remove the assignment and just call it directly

brisk zenith Sep 29, 2018, 8:53 PM

#

expressions can contain expressions

#

and if you want to make it an expression, you can assign with globals().__setitem__("calculator", lambda ...)

that was dunderful

pure dew Sep 29, 2018, 8:57 PM

#

theres some dunderful way to access modules without importing anything

brisk zenith Sep 29, 2018, 8:57 PM

#

yeah i know

pure dew Sep 29, 2018, 8:57 PM

#

we discussed it earlier for the challenge

joseph used it in his .. yeah

vague gust Sep 29, 2018, 8:57 PM

one expression done

frosty wyvern Sep 29, 2018, 8:57 PM

#

This is fully educational and is full of bugs, I have no real intention of developing this past the current state it is at

#

LOL

#

I love your attitude

vague gust Sep 29, 2018, 8:57 PM

#

lmao

#

i love my attitude as well

pure dew Sep 29, 2018, 8:59 PM

#

wait until you see my magnificent "its just a simple challenge, ill fix it later" code

brisk zenith Sep 29, 2018, 8:59 PM

#

this

#

actually

#

my code is better than what it was

#

it's split into like 6 files so far

pure dew Sep 29, 2018, 9:00 PM

#

lol

#

mines one and a repl wrapper

brisk zenith Sep 29, 2018, 9:00 PM

#

i'm actually trying to make my language relatively usable

pure dew Sep 29, 2018, 9:00 PM

#

im actually gonna polish this and upload it to pypi later

frosty wyvern Sep 29, 2018, 9:01 PM

#

Are you saying there is no market for a language that supports nondeterministic flow of operations such as mine and with no flow control?

pure dew Sep 29, 2018, 9:01 PM

#

uh ye

frosty wyvern Sep 29, 2018, 9:01 PM

#

and no functions

vague gust Sep 29, 2018, 9:01 PM

#

mine is like 4 files iirc

brisk zenith Sep 29, 2018, 9:01 PM

#

yes it is jos-b

pure dew Sep 29, 2018, 9:01 PM

#

no flow control isnt a huge deal

brisk zenith Sep 29, 2018, 9:01 PM

#

mine has control flow

#

but it doesn't have iteration. just recursion.

vague gust Sep 29, 2018, 9:02 PM

#

ty kingdom5500

#

or something like that

#

i forget the name

brisk zenith Sep 29, 2018, 9:02 PM

#

yeah

#

also how well-known is the raise ... from None syntax?

vague gust Sep 29, 2018, 9:06 PM

#

I've seen it before but never used it

#

pretty cool though

brisk zenith Sep 29, 2018, 9:07 PM

#

vague gust Sep 29, 2018, 9:08 PM

would be cool to be able to chain them though :^)

brisk zenith Sep 29, 2018, 9:08 PM

#

haha

vague gust Sep 29, 2018, 9:08 PM

#

i want something like this https://i.seph.club/sl8rd.png

brisk zenith Sep 29, 2018, 9:08 PM

#

raise ValueError from ImportError from ...

fallen heath Sep 29, 2018, 9:08 PM

#

What does the from None do

brisk zenith Sep 29, 2018, 9:08 PM

#

look at the example c:

vague gust Sep 29, 2018, 9:08 PM

#

stops it from tracing back past the immediate error

brisk zenith Sep 29, 2018, 9:09 PM

#

yup

fallen heath Sep 29, 2018, 9:09 PM

#

Ah

vague gust Sep 29, 2018, 9:09 PM

#

if you don't do that it will find the other error (ZeroDivisionError in the example) and show that as well

fallen heath Sep 29, 2018, 9:09 PM

#

One thing about pythons syntax that is still weird to me is the for else loop

vague gust Sep 29, 2018, 9:09 PM

#

i guess this'll have to do for now https://i.seph.club/1hafd.png

#

yeah I guess it's kinda weird but it does make sense

brisk zenith Sep 29, 2018, 9:09 PM

#

there's while/else

fallen heath Sep 29, 2018, 9:09 PM

#

Idk why but it just looks wrong to me

brisk zenith Sep 29, 2018, 9:09 PM

#

i actually really like it

vague gust Sep 29, 2018, 9:09 PM

#

there is no real way to describe what it does though

#

else is somewhat fitting

brisk zenith Sep 29, 2018, 9:11 PM

#

so, there's
if/elif/.../elif/else
try/except/.../except/else/finally
while/else
for/else
i can't think of any more things like that

#

i mean, else is everywhere

pure dew Sep 29, 2018, 9:18 PM

#

@vague gust just nest try catch blocks, raising from in each one

vague gust Sep 29, 2018, 9:20 PM

#

hmmm

brisk zenith Sep 29, 2018, 9:21 PM

#

make a script that generates the nested try/excepts given a string, each exception with a word from str.split()

vague gust Sep 29, 2018, 9:22 PM

#

oh my god it works @pure dew

#

https://i.seph.club/xlgu1.png

pure dew Sep 29, 2018, 9:24 PM

#

uh ye

vague gust Sep 29, 2018, 9:24 PM

#

https://i.seph.club/jlnx5.png

#

lovely

pure dew Sep 29, 2018, 9:24 PM

#

err

#

not quite my idea

vague gust Sep 29, 2018, 9:25 PM

#

thinking_egg

pure dew Sep 29, 2018, 9:27 PM

#

try:
    raise Exception("She")
    
except Exception as e:
    try:
       raise Exception("Took") from e

    except Exception as e:
        try:
            ...
``` you get the idea

vague gust Sep 29, 2018, 9:29 PM

#

no need to do the from though since it's auto-inferred in try/except

brisk zenith Sep 29, 2018, 9:35 PM

#

joseph as i said you should make a program to create the nested try/except blocks :^)

pure dew Sep 29, 2018, 9:41 PM

#

@vague gust true

vague gust Sep 29, 2018, 9:41 PM

#

@brisk zenith bro i can't be bothered

#

I like type type typing

brisk zenith Sep 29, 2018, 9:42 PM

#

i also like type(type(typing))

vague gust Sep 29, 2018, 9:43 PM

#

fuck he's good

brisk zenith Sep 29, 2018, 9:44 PM

#

now i'm curious, how does type(type) is type work?

#

like, how can type subclass itself yert

vague gust Sep 29, 2018, 9:47 PM

#

interesting

brisk zenith Sep 29, 2018, 9:47 PM

#

type(type)(type(type)) is type

vague gust Sep 29, 2018, 9:48 PM

#

>>> type.__subclasses__(type(type))
[<class 'abc.ABCMeta'>, <class 'enum.EnumMeta'>]

brisk zenith Sep 29, 2018, 9:48 PM

#

🤔

#

>>> type.__mro__
(<class 'type'>, <class 'object'>)
>>>

pure dew Sep 30, 2018, 2:23 AM

#

py-lci now (messily) handles free names colliding with bound names

(λx.(λy.xy) x) x -> (λa.(λy.ay) a) x

#

I spoke too soon, it only works in the outmost scope lmao

pine edge Sep 30, 2018, 4:42 AM

#

i started working on a biological programming language

#

where dna is the main computing element, e.g. the computations are just whether or not strands of dna bond because they have complimentary base pairs or not

#

and i was thinking about what dna could actually do, computationally

#

"well, strands of dna can pattern match"

#

"it'd be really awful to read and write just a whole bunch of 1d pattern matching strings"

#

"and the syntax would be godawful, using GCAT exclusively"

#

and then i realized it was literally regular expressions

#

regular expressions are 1 dimensional pattern matchers using terrible syntax

#

regular expressions match complexity with a language i was specifically trying to make hard to use

pure dew Sep 30, 2018, 12:49 PM

#

You can make a BF interpreter with regex too

brisk zenith Sep 30, 2018, 1:58 PM

#

progress on my esolang is almost completed, i just need to polish up a bit

I'm glad people are mostly done their entries. I'll be putting up a new challenge probably by tomorrow. Of course, feel free to keep working on this challenge even after the new one is up

Kingsley McDonald / esolang

the esolang i created for the 4th esoteric Python Discord challenge

#

my esolang so far

#

it just needs polishing a bit

#

i also need to rewrite some stuff

#

but yeah, the idea is that it's all valid python syntax, you've just gotta import the esolang and it'll work

sick hound Sep 30, 2018, 5:54 PM

#

right now that's not valid syntax

#

I think

brisk zenith Sep 30, 2018, 5:54 PM

#

oh it is

sick hound Sep 30, 2018, 5:55 PM

#

...wat

brisk zenith Sep 30, 2018, 5:55 PM

#

tfw you even confuse pastebean

#

PROGRAM [
    # this is the start of a slice now
    : # colons are a feature of slices, yes?
]```

sick hound Sep 30, 2018, 5:57 PM

#

yes but why does it have 5 slices

#

separated by commas

brisk zenith Sep 30, 2018, 5:57 PM

#

that's a thing

#

numpy uses that, actually.

#

>>> thing [:,:,:,:,:,:,:,:,:,:,:,:,:,:,:,:]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'thing' is not defined
>>>

you can have as many as you want

sick hound Sep 30, 2018, 5:58 PM

#

wat

pure dew Sep 30, 2018, 5:58 PM

#

how does should work tho

#

i cant see how thats valid syntax

brisk zenith Sep 30, 2018, 5:59 PM

#

() basically 'calls' SHOULD

sick hound Sep 30, 2018, 5:59 PM

#

>>> type('',(),{'__getitem__':lambda s,i:i})()[:,:]
(slice(None, None, None), slice(None, None, None))```

#

It's a tuple of slices

brisk zenith Sep 30, 2018, 5:59 PM

#

yes

sick hound Sep 30, 2018, 5:59 PM

#

because that's so readable and pythonic

#

why is that a thing

brisk zenith Sep 30, 2018, 6:00 PM

#

look up how numpy uses it

pure dew Sep 30, 2018, 6:00 PM

#

oh oh

#

its an index

brisk zenith Sep 30, 2018, 6:00 PM

#

yes

pure dew Sep 30, 2018, 6:00 PM

#

i was thinking lua-style function call

brisk zenith Sep 30, 2018, 6:01 PM

#

>>> def function(_):
...     return [1, 2, 3]
... 
>>> function (1 > 2) [ 1 ]
2
>>>

this is how it's syntactically valid

pure dew Sep 30, 2018, 6:01 PM

#

yea

brisk zenith Sep 30, 2018, 6:03 PM

#

i'm gonna continue working on it now

brisk zenith Sep 30, 2018, 6:53 PM

#

i should add some more stuff to the core module

#

any ideas? got print/input/int/str/float, can't think of anything else it would really need

#

there's also stuff like empty_stack

vague gust Sep 30, 2018, 7:06 PM

#

None?

brisk zenith Sep 30, 2018, 7:07 PM

#

hmm good idea, i'll do that at some point

#

i've already got null as a dummy identifier

#

as in, you can assign (well, pop) to null and it'll automatically discard the value

#

so basically /dev/null

brisk zenith Sep 30, 2018, 7:38 PM

#

i'm going to make a module for my esolang for super basic file operations

pure dew Oct 1, 2018, 1:47 AM

#

Ayy so it works now

((λx.(λy.(x y))) y) -> ((λx.(λa.(x a))) y)
(1 substitutions)

#

and it respects free variables in the function body
((λx.((λy.(x y)) y)) y) -> ((λx.((λa.(x a)) y)) y)

#

so short instead of fast, will be interesting to see

sick hound Oct 2, 2018, 11:17 PM

#

for these smaller mazes I wonder if it would be better to fill all white with dots, then remove any dots which aren't connected or have no use

pine edge Oct 2, 2018, 11:18 PM

#

that sounds like an optimization

#

you don't want that

#

unless of course you want a stable and fast solution

frosty wyvern Oct 2, 2018, 11:24 PM

#

I've never written any algorithms to solve mazes so I'm wondering myself what kind of solution will end up being more golfable, something more bruteforcy or an actual algorithm

#

and also whether writing an algorithm using the maze as a 2d list vs parsing the maze into a graph structure

#

shrugs

pine edge Oct 2, 2018, 11:31 PM

#

oh man there's only one solution per maze

#

that's important

sick hound Oct 2, 2018, 11:31 PM

#

well is a maze where all dots are filled in count as a valid path

@sick hound No, you can look at the test cases, though they're a bit hard to see in the format they're in in the json file

#

there's only one valid solution and its the direct path

#

the most direct path, that is

#

    🤔 lang should be pronounced "u+1F914 lang" or "colon thinking colon lang" on
    
    Discord, "please no thank you" also suffices.

#

you deleted a wall >:(

lol

#

unless i fucked up the test cases

which is very likely actually.

i mean it passed the first two tests so i'm very confused how it deleted wall here

#

I hope to be submitting a small version of my project for #03 tonight or tomorrow

frosty wyvern Oct 3, 2018, 1:21 AM

#

yea

#

the problem is in the test case @pine edge

#

sorry <3

pine edge Oct 3, 2018, 1:23 AM

#

but yeah about the question of how golfable brute force maze functions are

#

mine is a depth first search

frosty wyvern Oct 3, 2018, 1:25 AM

#

hold on trying to fix this dumb shit : )))

pine edge Oct 3, 2018, 1:25 AM

#

and it's about 221 characters depending on if it passes the fixed tests or not

frosty wyvern Oct 3, 2018, 1:25 AM

#

okay so

#

i fixed the test(I think)

#

HOWEVER

#

The thing I broke in the original test

#

meant that there was no test case where it was possible for a path to loop in circles

#

so lets see if it still passes haha

#

uhm

#

do you wanna just monkey patch your testcases.json file

haha whoops that's a merge conflict

#

but yeah i wrote this function so it will always return the shortest path, but if there is a second, longer path, it will find it

#

and then because it's written to take advantage of the fact that only one path exists it will immediately crash

#

so if it returns, it is the shortest path

frosty wyvern Oct 3, 2018, 2:06 AM

#

gah is there a way to resolve that on the site

#

if not can you just do a new commit and only include your solution file :DDD

pine edge Oct 3, 2018, 2:36 AM

i was hoping it would merge automatically because we both have the same file, but it's upset that we made the same file separately

@frosty wyvern isn't latest challenge just to write Dijkstra and making distances with walls a ridiculously high number?

@grave rover hi

grave rover Oct 8, 2018, 9:22 PM

#

Sup daps

frosty wyvern Oct 8, 2018, 9:45 PM

#

@grave rover What? The challenge is code golf. The algorithm is irrelevant, it's whatever solution you can write the most succinctly

grave rover Oct 8, 2018, 9:47 PM

#

But isn't that realistically the best method to do this other than trying everything and taking the shortest path?

teal rune Oct 8, 2018, 10:07 PM

#

doesn't matter, golf it

frosty wyvern Oct 8, 2018, 11:11 PM

#

@grave rover The goal is simple, write ANY code that solves the problem, it doesn't matter if it's efficient or not, as long as it solves the problem, and make it as short as possible

#

Perhaps Djikstras, perhaps a bruteforce solution. Depends how you implement it and who can implement it in the fewest characters

#

Need a way to subscribe to these

arctic bridge Oct 9, 2018, 2:55 AM

#

I'm not made for these challenges

#

Not great at algorithms, so my first thought goes to "what would be the most wacky solution that's still technically within the rules"

#

Well, ok, train a machine learning algorithm on the solutions, obviously

#

But, no imports!

#

Well, we use pip inline with:

from pip._internal import main; main('install tensorflow')

#

But that's an import!

#

Well, we put it in a different .py file that's on a GitHub gist, which is then linked to by a bit.ly link

#

To avoid imports of urllib, we determine the OS type by attempting to read OS-specific files

#

We then read the contents of urllib/request.py and exec:

exec(open('C:\\Program Files\\Python36\\Lib\\urllib\\request.py').read())

whole kiln Oct 9, 2018, 3:08 AM

#

I like your line of thinking

#

causing chaos

arctic bridge Oct 9, 2018, 3:13 AM

#

Now that we have urllib in our grubby not rule breaking technically probably please don't hurt me Shawn hands, we get the file:

urlretrieve('https://https://bit.ly/2E8iGuS', filename='evil.py')
exec(open('evil.py').read())

#

Then we simply call our solution, where i is the test input string:

f(i)

#

@frosty wyvern How's that

#

name resolution fails for me. It's not compatible with pihole

Challenges Update

Greetings. Esoteric Python challenges will be on hiatus starting now and for the duration of the code jam. If you haven't signed up yet and would like to, hurry because the signups close this weekend!

https://pythondiscord.com/jams

As for the challenges and this channel in particular, do feel free to take a look at the various challenges if you haven't yet and try your hand at any of them! I welcome Merge Requests for solution submissions even for past challenges. If you have any challenge suggestions, comments, ideas on how we could make #esoteric-python events more exciting, etc. Feel free to DM me on Discord. We only have a small handful of people who regularly participate in the challenges which is fine, given that this is esoteric python and not everyone is interested in Golfing or various challenges but I would still love ideas on how we could get more people involved!

Our GitLab Repository for challenges: https://gitlab.com/python-discord/esoteric-python-challenges/

Python Discord | Code Jams | Home

We're a large, friendly community focused around the Python programming language. Our community is open to those who wish to learn the language, as well as those looking to help others.

python one liner i made to encode a string using a variation of the caesar cipher, where every letter is shifted by its position in the string

print("".join([list(map(chr, range(97, 123)))[(list(map(chr, range(97, 123))).index(char)+i) % len(list(map(chr, range(97, 123))))] if char in list(map(chr, range(97, 123))) else char for i, char in enumerate(input("string to encode: "))]))```

cunning wave Oct 13, 2018, 7:43 PM

#

thats not a variation of the caesar cipher, the caesar cipher has at least some kind of key

broken mesa Oct 13, 2018, 7:44 PM

#

the caesar cipher shifts the letters by 3

#

normally

cunning wave Oct 13, 2018, 7:45 PM

the caesar cipher shifts the letters by n

#

caesar just used to use 3 always

broken mesa Oct 13, 2018, 7:45 PM

how does it makes this not a variation?

cunning wave Oct 13, 2018, 7:45 PM

how is mine not?

if its not even a cipher

it cant be a variation of one

here nobody has the option to choose anything

broken mesa Oct 13, 2018, 7:47 PM

okay i get it now

you need to be able to select a starting point

cunning wave Oct 13, 2018, 7:48 PM

you need to be able to select a key

mathematically speaking a symmetric encryption function (which is what caesar cipher is) is a function taking the clear text and a key

what it does with that is up to the function

#

okay time to improve my Pyed Piper module

#

I should add another o perator that creates a Thread

#

like..

#

hmm

#

i wanna add concurrency

#

im not sure how to model it though

#

I need an esoteric code guru like @brisk zenith

#

I guess I could just do like

brisk zenith Oct 13, 2018, 9:26 PM

#

hello

frosty wyvern Oct 13, 2018, 9:26 PM

#

hmmmmmm

#

ok Juan you need to help me figure this out

brisk zenith Oct 13, 2018, 9:26 PM

#

okay

frosty wyvern Oct 13, 2018, 9:26 PM

#

I want to add onto my Piping shitcode some concurrency like

#

 P
| a
| b
& a1
& a2

#

errr

#

this is gonna get complicated vvv quick

brisk zenith Oct 13, 2018, 9:27 PM

#

hmm okay

frosty wyvern Oct 13, 2018, 9:27 PM

#

cause what are the inputs where do the outputs even go

#

how does the P object handle waiting for threads

#

imma start cleaning the apt and think about it, help me brainstorm you little genius

brisk zenith Oct 13, 2018, 9:31 PM

#

(btw why don't you use metaclasses to make it so you don't really need to initialise your class when you want to use it?)

frosty wyvern Oct 13, 2018, 9:34 PM

#

(I don't know how to use metaclasses I've never used em)

#

can you convert my current code into a metaclass so I can learn from the sensei

brisk zenith Oct 13, 2018, 9:35 PM

#

i'm thinking something like

(P ([1, 2, 3, 4, 5])
 | print  # prints the list
 & "my_thread", sum  # spawn a thread called "my_thread"
 | print  # still prints the list
 @ "my_thread"  # get (or wait for) the output of the thread
 | print  # now prints the result of the `sum`
)

#

wow thank you syntax

#

a metaclass is basically what creates class objects

#

cause everything is an object, even classes

#

the main metaclass is actually type (remember how i used that to define a class in my one-liners?)

#

so subclassing type allows you to make a metaclass

#

and i'm thinking that you could pass multiple arguments like ```py
(P (2)
| print, "my number =", ... # my number = 2
| print, ..., "is my number" # 2 is my number
)

#

cause that's valid syntax

#

it just creates a tuple of (func, *args)

#

and ... would be replaced with the pipe value

frosty wyvern Oct 13, 2018, 9:42 PM

#

you're a pipe value

brisk zenith Oct 13, 2018, 9:42 PM

#

wow thank you so much! :D

#

but you should also allow people to change this magic ... value in case they want to actually pass Ellipsis to a function

#

in which case you would make a different singleton so that you can check with is consistently

frosty wyvern Oct 13, 2018, 9:43 PM

#

btw doing | fn, arg, arg doesnt seem to work without the ( )

brisk zenith Oct 13, 2018, 9:43 PM

#

really?

frosty wyvern Oct 13, 2018, 9:43 PM

#

unless its just my current code thats fucky

i'm rethinking this and don't think a metaclass would be ideal if we want user-changeable values

#

i.e if they want to change the value of the ...

#

maybe you could have a bunch of singletons for different things

#

teeing would be interesting

#

like, ```py
(P(2)
| print T # prints the value of the pipe (2) but also replaces the return of print with the original pipe value of 2
)

#

well, however you want your syntax to work

frosty wyvern Oct 13, 2018, 9:48 PM

#

oo cool

#

is that a thing or what

#

teeing

brisk zenith Oct 13, 2018, 9:48 PM

#

teeing? well, you have tee in linux which sorta does something similar

frosty wyvern Oct 13, 2018, 9:48 PM

#

oo cool

#

oo is the symbol like a T_ shaped pipe where the shit falls down into something but also keeps going in the same direction

brisk zenith Oct 13, 2018, 9:49 PM

#

yup

#

beautiful

brisk zenith Oct 13, 2018, 9:50 PM

#

very

#

and good for pipes

#

cause the return value of None in print is annoying if you want to keep your original value, for example

frosty wyvern Oct 13, 2018, 9:50 PM

#

Yep

#

ok well

#

heres the thing

#

how would I implement those other symbols

#

cause they not operators

#

I make em constants?

#

that get interpreted?

brisk zenith Oct 13, 2018, 9:51 PM

#

i don't think they'd need to be operators

#

what syntax are you going with for arguments?

frosty wyvern Oct 13, 2018, 9:51 PM

#

shrugs :)

#

the ellipsis is pretty dank

brisk zenith Oct 13, 2018, 9:52 PM

#

(P(2)
 | (print, T)  # prints 2, passes 2 down the pipe
 | (print, ...)  # prints 2, consumes the value
 | print  # prints None, because the above `print` returned that
)

is what i'm thinking

frosty wyvern Oct 13, 2018, 9:53 PM

#

yeeeeee

#

Agreed

#

hm

#

I feel like

#

(P(2)
 | (T, print)
 | (print, ...)

#

is a bit more visually appealing

#

cause the T is closer to the pipes

#

: )

brisk zenith Oct 13, 2018, 9:54 PM

#

yeah, it makes more sense

#

but then, where does the value get passed to the print?

#

i suppose ... would have to be used there too

#

so py (P(2) | (T, print, ...) | (print, ...) )

frosty wyvern Oct 13, 2018, 9:54 PM

#

well if it's just a function id say it gets implicitly passed

brisk zenith Oct 13, 2018, 9:55 PM

#

yeah but what if the function takes multiple arguments

#

which one is given the pipe value?

frosty wyvern Oct 13, 2018, 9:55 PM

#

whatchu mean

brisk zenith Oct 13, 2018, 9:55 PM

#

as in,

#

(btw i think T should be a function/callable object, which executes the function and returns the value)

#

(P(2)
 | T(print, "shawn is", ..., "years old")
 | (print, ...)
)```

frosty wyvern Oct 13, 2018, 9:57 PM

#

aw yeah cause thatll just evaluate to the original value and i can just keep chugging along

brisk zenith Oct 13, 2018, 9:58 PM

#

yup

#

i don't think ... should be implicitly passed either, cause maybe there's a function that doesn't take any arguments at all

frosty wyvern Oct 13, 2018, 9:59 PM

#

yeah if we're Tee-ing then it might make sense to call something that takes no argument

#

but like otherwise it kinda ruins the whole pipe thing

brisk zenith Oct 13, 2018, 10:00 PM

#

yeah true

frosty wyvern Oct 13, 2018, 10:00 PM

#

if ... isnt implicit in regular pipes then its like why bother cause its no longer like a unix pipe at all

#

at that point im just complicating calling functions LOL

brisk zenith Oct 13, 2018, 10:00 PM

#

yeah that's a good point to be fair

#

i suppose if you have a function that needs to be called without any arguments, you could just do T(my_argless_func()) and that would work just as well

#

but then that requires a normal function call yert

frosty wyvern Oct 13, 2018, 10:02 PM

#

This indexes the 0th constant with the 1st, 2nd and 3rd constants, then calls the function with the first name with those arguments in that order without using * or **

does anyone know some relatively serious languages written in python?

green nymph Oct 18, 2018, 3:48 PM

python

cunning wave Oct 18, 2018, 4:16 PM

#

the python you use is not written in python, at least not the language part

#

cpython (the interpreter the majority of people uses) is written in C and the enormous stdlib is written in python

#

then there is the pypy interpreter (also interprets python) which is written in rpython

#

and then there are a few smaller languages such as hylang for example which is written in python and uses the python vm

fallen heath Oct 18, 2018, 4:18 PM

#

jython, a java implementation

cunning wave Oct 18, 2018, 4:18 PM

that is not written in python though

#

the question was for langs written in python

tropic gulch Oct 18, 2018, 4:18 PM

#

what do you even mean by "language written in Python"? You can't write a language in another. That's like saying I write Spanish in French. And interpreters for languages can be (re)written in any language.

-1 is an internal error code of cpython

# # # # # # # # # # # # # # # # #

class Blah(metaclass=Meta):
    thing = 1
    thing = 2```
is there a way to get this to "work" or is it just completely impossible because the class vars are handled before anything to do with the metaclass

#

(the assignments to thing don't trigger the setter func)

pine edge Oct 20, 2018, 8:57 PM

#

@sick hound object.__setattr__(self, name, value)¶ Called when an attribute assignment is attempted. This is called instead of the normal mechanism (i.e. store the value in the instance dictionary). name is the attribute name, value is the value to be assigned to it.

sick hound Oct 20, 2018, 8:59 PM

#

?

grave rover Oct 20, 2018, 10:20 PM

Override setattr instead, it'll make it less of a pain

fallen heath Oct 20, 2018, 10:22 PM

#

or @property

sick hound Oct 21, 2018, 1:45 AM

#

i'm not sure if i'm missing something but

i know what __setattr__ does @ seinfeld :p and overriding it should in theory have the same effect as writing an @property so i wasn't sure why you posted that doc quote
overriding __setattr__ doesn't work here, so i went on to try @property -- that's the codeblock i posted

#

it looks to me like class-var assignments (that are done within the body of the class itself) happen before anything from the metaclass happens, even if Blah.thing = 1 later on would behave appropriately
(so then I'm not sure if this problem in turn has anything to do with that the name of a class isn't bound within its own scope??)

pure dew Oct 21, 2018, 1:49 AM

whoops sorry for not catching that extra bit of complexity

#

uhhhh

#

i checked by disassembling some python functions

#

and when you set a variable in a class definition like that the bytecode is doing a STORE_NAME

#

but the thing __setattr__ catches is STORE_ATTR

#

i can't think of any mechanism short of parsing the program yourself with something like ast to check to see if this happens

glacial rampart Oct 21, 2018, 3:04 AM

im not sure wether its a valid URL

#

but its a valid URI

pure dew Oct 21, 2018, 1:32 PM

#

well ye

brisk zenith Oct 21, 2018, 2:33 PM

#

it would be so convenient to be able to have a function called whenever a variable is accessed. i can achieve it easily with global variables, but not at all with local variables.

#

this is what the locals builtin does ```c
static PyObject *
builtin_locals_impl(PyObject *module)
{
PyObject *d;

d = PyEval_GetLocals();
Py_XINCREF(d);
return d;

}

#

that's all very simple

#

it just calls PyEval_GetLocals and assigns it to a python object

#

now, accessing a local variable doesn't actually use the locals builtin to look it up, it uses this PyEval_GetLocals function

#

which is why i want to somehow monkeypatch PyEval_GetLocals

#

oh no i just found a goto in cpython

#

#define GETLOCAL(i)     (fastlocals[i])```

#

getting closer to the root of it i suppose
