instead of
for iteration in range(len(some_flippity_floppity_funny_looking_array_thingy)):
do_thing(iteration, some_flippity_floppity_funny_looking_array_thingy[iteration])
You name your variables in one letter if possible, and turn for loops into generator expressions.
[f(i,e)for i,e in enumerate(a)]
f,i,e, and a are, respectively, standard abbreviations of instances of function, iteration, element and array
think of your keyboard as your namespace. Each key is a variable, operator, or literal. you can still use builtins, but only if they're needed. Try to only name them once. Same as 3rd party API like discord.py
!e example of only calling a full name once, only using brackets once, not newline separating classes, only using one letter for names, except for dunders, and not allowing spaces between operators. Only use middleman variables if they will shorten your code.

would even be useful if you could trigger an event for clicking on something in the terminal :/
i.e. the buttons
so then i could make a graphical user interface with just unicode in a terminal
so what if i made a fake terminal using a kivy TextInput?
Then i'm free from the limitations of the terminal
and i can make an arbitrary object with a touch trigger with the coordinates of the buttons coded in.
but then i can't really test it with the bot.

Well, you're trying to dereference random addresses after the id of an object which isn't valid. You have no idea what's in those bytes, though there's definitely not valid objects 16 bytes from the start of your class instance. Objects are in general randomly placed in memory....
floral meteor
you have a good point, but the type of an object is stored at id(obj)+8
I would presume there's more data following
sick hound
nice 
simple crystal
you have a good point, but the type of an object is stored at id(obj)+8
..or + 4 on 32 bit
simple crystal
they're ssize_t sized in cpython distros tho right?
simple crystal
or at least get packed that way in pyobjects
is all I care about haha
but I checked in c
and they are that size when I check in c
grave rover
Used for a count of bytes. It is the result of the sizeof
operator. According to the C language standard, it shall
be an unsigned integer type capable of storing values in
the range [0, SIZE_MAX]. According to POSIX, the implementation shall support one or more programming environments where the width of size_t is no greater than the width of the type long.
Damn you android copy-paste
Actually, i know on my distro that a pointer is as big as a longlong
grave rover
But so is a long long apparently
grave rover
Longs are same size as long long
simple crystal
neve rused a long long
grave rover
I think it's because longs are not guaranteed to be bigger than ints?
simple crystal
my long longs are 8
everything else is 4
I think my C is in 32x tho
for whatever reason
I didn't even install C manually it's just on clion idk what it is
pointer:4 long long:8 long:4 size_t:4 ssize_t:4 int:4
ah yeah it's building 32 bit
potent comet
why does it need 64 bits to store a memory address?
A 32-bit pointer can only address up to 2ยณยฒ locations, which is a little more than 2 gigabytes of RAM. So if you want to have a program that can allocate more than that, it needs a larger size. Hence 64 bits, which is more than enough for the foreseeable future.
stark fable
A 32-bit pointer can only address up to 2ยณยฒ locations, which is a little more than 2 gigabytes of RAM.
...2^32 locations is 4 gigabytes
but aside from that, yeah, that's what the reason is
64-bit pointers are enough for 18 exabytes of RAM which is... a lot
proper vault
modern archs only use 48bits for addresssing though
grave rover
they still align to 64bit in most cases tho
proper vault
ye, its 64bit values, but the high 16 are not part of the address
mild spire
Can someone pm and help me reword code so I donโt plagiarise
twilit grotto
that's still plagiarism

snow beacon
Isn't there one in io?
floral meteor
how would I set what it... does?
snow beacon
If I recall, you give it a string, and it pretends to be a file.
floral meteor
ah, a string.
I've been making an entirely new File class, that behaves like open() only it doesn't block the file.
after all, whenever i use file reading, i haven't done anything that needs to block it.
here's a preview, I haven't added 'invincibility' yet, since try except suites are bugger to write esoterically.
__eq__ =lambda s,p:s.name==p.name# or s.read()==p.read() #<review>
__ge__ =lambda s,t:t[1]<=(t[0],str(s)) # [__str__]
__and__ =lambda s,o:s and o# []
__or__ =lambda s,o:s or o # []
__str__=__repr__=lambda s:s.read() # [read]
__int__ =lambda s:len([(f:=open(s.name)).read(),f.close()][0]) # [__init__]
__bool__ =lambda s:os.path.exists(s.name) # [__init__]
# file-like-methods
read=lambda s,n =- 1:[(f:=open(s.name,'r')).read(n if n>0 else n and int(s)),f.close()][0]if self.readable else NotImplemented # [__int__]
write=lambda self, s:[(f:=open(self.name,'w')).write(s),f.close()][0]if self.writable else NotImplemented # [__init__]
readable,writable,seekable,closed=True,True,True,False # []
seek=lambda s,p,m=0:setattr(s,'__p',p if not m else s.__p+p if m<0 else int(s)-p)if s.seekable else NotImplemented # [__int__]
reconfigure=lambda s,d='r+',**k:[setattr(s,n,v)for n,v in({'readable':'r'in d or'+'in d,'writable':'w'in d or'+'in d or'a'in d,'seekable':True}|k).items()]
# idk
_CHUNK_SIZE,write_through=8192,False
close=flush=lambda*a,**k:None # []
fileno=lambda s:[(f:=open(s.name,'r')).fileno(),f.close()][0] # [__init__]
buffer=type("None",(object,),{'__doc__':"Does not need a buffer"})()
The comments are just dependency tracing
except for the first one
everything after idk is guessing
snow beacon
If you're okay with imports you could do your file closing more safely with e.g. pathlib.
floral meteor
but i don't like the whole with open(filename,perms) as file: c=file.read();file.seek(3);file.write("whatever") and all that i just like a nice, concise, explicit
+File(filename) # you get it? 'plus file' add a file XD
File(filename) << "from cursedutils.death import blue_screen_induction_protocol\n"
File(filename) << "blue_screen_induction_protocol()"
__import__(filename) # blue screen go brrrrrr
snow beacon
I think that's what pathlib tries to be.
I just use it for the handy methods.
There's one that reads a whole file, which is usually what I want to do.
floral meteor
i saw pathlib recently and i thought hmmm, that might come in handy
I've gotten as far with pure python tho :/
I havent' fiully impleemented seeking tho
also open(filename,'r').reconfigure('w') crashed python
rugged sparrow
Woah, that's really useful. Could it work for __bool__ to specialize for and/or/...

floral meteor
I'm working on a file-like object with extra iostream dunders
toxic jewel
jut using vivid on phone and cityshow on computer
floral meteor
I just decided i'd return the object after an operation instead of the data passed to it
does __hasattr__ method of object call __getattr__?
terse mortar
I assume it checks if getattr:
floral meteor
so that's why it gives recursionerror when i tell it to
def __getattr__(self, other):
if hasattr(self,other):return super().__getattr__(other)
else:return print (other)
so how do I circumvent this circular referencing and still accomplish the same thing?
terse mortar
Try returning getattr without the dunder maybe?
floral meteor
it doesn't reach that, i don't think :/
terse mortar
Well you are probably getting recursion bc you are using the dunder inside the definition
So try to replace the super().getattr blah blah with getattr(self, other)
floral meteor
__getattr__ <-
if hasattr <-
whatever(getattr(s,o))<-
getattr <-
obj.__getattr__ back to the start
hence it's back to the start before it even gets to return super().__getattr__(other) or else:
since hasattr seems to within itself call obj.__getattr__
terse mortar
Ahh true
Hmm
Ig you could try looking at how base python defunded them
Or try this ig
x = getattr(self, other)
return x if x != None else return print (other)
hm.
try:return super().__getattr__(other)
except AttributeError:return print (other)
Might work actually
terse mortar
That might also work
simple crystal

nice, but I mean I wondered if anyone has experimented with adding tp_as_mapping mp_ass_subscript aka__setitem__ to string literals so they behave like mutable sequences, though you'd probably want to just make a new string behind the scenes rather than figuring out if the string is interned with multiple references and dealing with that

nice, but to do what I meant you'd need to make something initally defined as a string literal behave that way
so you'd need to mess with the internals of the language, in CPython you'd need to at least move some pointers around
idk exactly how you'd do it because I'm not sure how to navigate to the relevant struct in the PyUnicodeObject hierarchy but I imagine it can be found by diving into the pointers in the top of whatever a str literal is
some sort of PyTypeObject
I debate whether to get more into knowing what CPython does or to switch to PyPy

floral meteor
p = type('p', (type,), {'__lt__':print})("p", (), {})
p < 'eyyy no brackets ehhh'
is a lot of brackets
simple crystal
you can import p from whatever module has p = type('p', (type,), {'__lt__':print})("p", (), {}) in it
floral meteor
that's 12 brackets
simple crystal
how many brackets in your iostream module?
floral meteor
there's a way to print hello world no imports 0 brakcets
floral meteor
characters 32, 40, and 41 are forbidden
simple crystal
oh you can use []
floral meteor
neh, i'll forbid those as well
bruh i was having fun here
i know you know the answer
rugged sparrow
oh whoops
simple crystal
no
floral meteor

@rugged sparrow come join the fun
@simple crystal chilaxin just casually did it in pure python.
while you looked away for a moment or whatever you were doing
simple crystal
I give up haha how is it done?
floral meteor
bruh don't give up
you've only been at it for 15 minutes
keep trying
think of how to call methods without using brackets
!e like for example
a = 3 + 4 # <- this
print (a) #calls
b = 3 .__add__(4)#this
print(b)
@floral meteor :white_check_mark: Your eval job has completed with return code 0.
001 | 7
002 | 7
so + is a shortcut to call __add__ method of something
so you want a... shortcut to call print
@simple crystal you legit quit?
floral meteor
dunder is just one way to call a method or function
not the only way
think of other ways
i'll give you a clue: it is not backwards compatible.
i.e. python 3.9 +
okay i'll drop a massive clue, have you ever worked with discord bots?
floral meteor
dm me
oh wait
yeah you just need to make a statement with an equals sign beforehand
viscid nymph
wait you just want to print without brackets?
snow beacon
And without imports.
viscid nymph
a callable that takes a single paramater
that implementation would need a meta class

@viscid nymph :white_check_mark: Your eval job has completed with return code 0.
Hello world!
i had to look up what char brackets were i already knew ' '==chr(32)
i said brackets and spaces

@floral meteor :white_check_mark: Your eval job has completed with return code 0.
Hello World!
no you didn't
but that's 2 spaces

i later forbade spaces as well

instantiating a whole ellipsis without using smh

what lol
floral meteor
@print
@lambda _:_.__doc__
class _:"""Hello World!"""
Is far more elegant.
simple crystal
but it has 2 spaces
floral meteor
true...
alpine flower
hold up __doc__ is a thing?
viscid nymph
I can get it to one space but that's it
floral meteor
dammit now i gotta thonk of a way to make class without space
viscid nymph
@print
@lambda*_:_[0].__doc__
class _:"""Hello World!"""
just need to make the class without space
rugged sparrow
you cant
floral meteor
ah but that uses square brakcets
square brackets still brackets
although for backwards compatibility probably do
pipe=lambda _:_.__doc__
@print
@pipe
class _:"Hello World!"
but you need a space after keywords unless you use a character that isn't legal in names
floral meteor
but then you'll need to use square brackets to undo the packing
viscid nymph
square brackets still brackets
really
simple crystal
by tacking stuff onto the challenge you made it impossible lol

Hello, world!
So if i set mp_subscript and sq_item to NULL and set tp_dict[getitem] to a py func, would that work?
rugged sparrow
@grave rover no because there needs to be a slot func that grabs __getitem__ from tp_dict
the default slot funcs for normal classes work
so you can make a class like py class Foo: __getitem__ = None then grab its mp_subscript and sq_item slot func addresses and set them in the target class
then add your custom __getitem__ to the target class tp_dict
then call pythonapi.PyType_Modified(cls) on the target class (or reimplement it, it just recursively toggles a bit-flag)
grave rover
But mp_subscript needs to be a funcptr, no?
Or does that get taken care of by how it's called
rugged sparrow
mp_subscript does need to be a func pointer
you just grab mp_subscript from Foo and set that value on target
my fishhook library on pypi does all of it automatically
thin trout
!e ```py
#coding:unicode-escape
@print\x0a@lambda*_:'Hello,\x20world!'\x0aclass\...
This is why we can't have nice things as PEP614 
simple crystal
Or does that get taken care of by how it's called
https://paste.pythondiscord.com/locisenola.py here is my module that basically does what fishhook does but only to __getitem__, __setitem__, __mul__, and __add__ for lists
it also copies the structs with the dunder pointers to allocated memory cuz chilaxan said to ensure they didn't deallocate
might help to see it all in front of you cuz it took me a long time to decode what fishhook does haha
grave rover
you just grab `mp_subscript` from `Foo` and set that value on `target`
the problem is that I can't find that on a python-defined class, it's just null
simple crystal
for mp_subscript you need to get void pointer to id of class plus 14*size_of_ssize_t to get to the mapping methods pointer
then get a pointer to the value of that pointer plus 1*size_of_ssize_t for mp_subscript
heap_tp_as_mapping = c_void_p.from_address(id(YOUR_CLASS_HERE) + 14 * size_of_ssize_t)
then heap_mp_subscript = c_void_p.from_address(heap_tp_as_mapping.value + 1 * size_ssize_t)
grave rover
I mean I have that implemented already
simple crystal
ah
grave rover
class Test:
def __getitem__(self, item):
return item
print("mp_ass_subscript ptr:", get_view(id(Test), CPyTypeObject.instance()).tp_as_mapping.mp_ass_subscript)
this prints 0
grave rover
binaryfunc is just a C function pointer type
simple crystal
ohhhh
grave rover
but Test.__getitem__ is a CPyFunction iirc
simple crystal
I don't think a heap class dunder is actually pointed to there
I think I found them a few ssize_ts from the head of the struct for some reason?
grave rover
Working on mapping out the entire thing (R is interpreted as P when it comes to size/alignment)
well i did seem to miss tp_as_sequence but that's fixed now
grave rover
I'll be honest I have no clue what pointers are set to what in that giant blob of code lol
simple crystal
it's pretty daunting lol
any clue as to getting ctypes to not hang when attempting to cast random stuff?
would be nice to brute force explore but it's impossible with a loop cuz of that
grave rover
I feel like there's something wrong in my typedef, I'm having issues where tp_dict holds the value of tp_base, hmm
simple crystal
could like, store current value being used and terminate program externally if it runs too long without output
restart with next value to test
I assume it's just runnin wild in memory trying to find an end
and that's why it ruins everything

``` so what pointers here do I need to change for this to workprint(str.__getitem__) gives print, so I'm not sure what else to change
simple crystal
ur gettin dict 2 slots from the id of the __dict__ right
grave rover
what do you mean?
simple crystal
the actual dict of a built-in is usually 2 slots from the id
grave rover
str_dict is of type dict, not the mappingproxy
simple crystal
oh
oh did you create a mapping struct for strings?
seems like they'd use sequence
or rather for whatever string typeobject you're dealing with
I'm gonna go to sleep, good luck
grave rover
I didn't, but i don't think that matters does it?
Or do i have to set the existing pointer to null

I made my own "language" type thingy with Python that also had loops
this was the syntax lol py Loop() @ (lambda x=0: (x, x < len(numbers), x + 1)) & inherits( {"Loop": Loop, "numbers": numbers, "hashMap": hashMap} ) > ( "code", "here" )
it's a language dedicated to mocking Java :)
here's the code for that: https://paste.pythondiscord.com/nemaparixo.py
grave rover
while cond: body can also be done like f = lambda: (not cond) or (body(), f()) iirc
rugged sparrow
oh yea @grave rover the benefit of stealing the func pointer from a python class instead of just using CFUNCTYPE is that the func you grabbed handles exceptions correctly
grave rover
Oh neat
rugged sparrow
it also means you can modify the behavior of base classes in pure python (no imports) because you only need memory r/w
rugged sparrow
str.tp_base = int?
rugged sparrow
I wonder what'll happen if i change the base class of str to int
doesnt seem to do anything
@grave rover does your code only use /proc to access python's memory?
autumn saffron

@nocturne saddle
grave rover
Why are you importing embed as numpy 
autumn saffron
because why not?
rugged sparrow
/proc/self/mem is all i needed
its possible to get r/w memory that is cross platform without imports tho
rugged sparrow
rn my code abuses LOAD_CONST to make arbitrary pyobjects
autumn saffron
same
rugged sparrow
so i can make a memoryview that points from 0 -> MAX 64bit int
autumn saffron
thats a lot of memory
autumn saffron
is the load_const thing a bug or feature
rugged sparrow
i make the custom memory view by first making a bytearray object that points from 0 to max int then turn it into a memoryview so i can use getmem to request subsections
@autumn saffron it is due to an optimization, inside the LOAD_CONST bytecode there is no bounds checking
rugged sparrow
i also use a second smaller bug in EXTENDED_ARG to overflow oparg to negative if needed
definitely a bug
autumn saffron
ok so it might be fixed later on?
rugged sparrow
its unlikely to be fixed
grave rover
And is memoryview readable like a file?
autumn saffron
why? is the optimization that big?
rugged sparrow
And is memoryview readable like a file?
i dont think so, but you can use it with io classes or make a fake file class
grave rover
Hmm
rugged sparrow
why? is the optimization that big?
yes because they just index the items directly with the oparg
grave rover
Meh, screw windows anyways
rugged sparrow
/proc doesnt exist on darwin either
grave rover
Screw darwin
rugged sparrow
you could also make a fake file object that maps into ram (which is what procfs does i think)
that would be trickier tho
why are you so adamant about it being a file object?
grave rover
Because rewriting everything right now to use a bytearray would not be a fun experience
rugged sparrow
fair enough
grave rover
A lot of my code relies on the file object keeping track of the current position and only using offsets, that way i don't have to seek for everything
Basically the only time I seek is when i get the address of an object to create a view of
rugged sparrow
ah
one sec i think there is a way to interpret memory as a file
@grave rover io.BytesIO for some reason creates a copy of the passed in buffer
grave rover
well yeah because otherwise you could very easily break stuff
rugged sparrow
Yeah but it should be using the buffer interface
Because if it did that you could pass in any buffer like object and it would just work
grave rover
True
rugged sparrow
@grave rover what methods do you actually use on the file object
cause you could just make a shim class

Also, is that _=memory_backing needed? I'm trying to just return memory but it seems to segfault
rugged sparrow
Also, is that _=memory_backing needed? I'm trying to just `return memory` but it...
You need to keep a reference to memory backing otherwise it gets freed
rugged sparrow
<@!274715613115711488> why do you hardcode using LE instead of native byteorder?
Python is little endian on most if not all sensible systems
grave rover
ah
grave rover
Python is little endian on most if not all sensible systems
safest to just use sys.byteorder tho
grave rover
You need to keep a reference to memory backing otherwise it gets freed
I'll just increase ob_refcnt by 1
SSIZE_T = (TUPLE_HEADER - PTR_SIZE) // 2 # TUPLE_HEADER = nPn -> n = (TUPLE_HEADER - PTR_SIZE) / 2
...
backing_addr = id(memory_backing)
memory[backing_addr:backing_addr+SSIZE_T] = (2).to_bytes(SSIZE_T, sys.byteorder) # Prevent GC
return memory
That requires an import tho
grave rover
fair enough
but yeah you can use the rest of that snippet to prevent having to make a nested function for keeping a reference
rugged sparrow
but yeah you can use the rest of that snippet to prevent having to make a nested...
Yes but I prefer to have it be referenced properly somewhere in case I need to do cleanup
rugged sparrow
safest to just use sys.byteorder tho
Found a way to do it with memoryviews I think
grave rover
oh?
rugged sparrow
'little' if memoryview(bytes([1,0])).cast('h')[0]==1 else 'big'```that is so nasty I love it
rugged sparrow
Afaik .cast defaults to native endian
I don't have any big endian stuff rn to test tho
@grave rover the technical reason why you need to hold onto memory_backing is because it contains the memory that supports memory. so it looks like this in memory <memory_backing:Bytes_Header, <memory:ByteArray_Header, ByteArray_Data>>
so if memory_backing gets freed, it corrupts our fake bytearray memory
grave rover

Hello
final night
Next i'm trying to figure out how to abuse use conditional execution to simulate an if-else statement
Is there a concise way to write this sort of statement?
True and (True;print("1")) or print("2")
I could wrap print in a lambda statement but I sorta want to avoid having to do that every time
Essentially if the statement is true, we eval the first one
otherwise we eval the second
hmm I wonder if I could use an or
oh hey, yeah, that totally works :D
this is pretty cool
(not True or print("1")) and print("2")
now I just need to re-order the operations so it doesn't need parens, if possible
I bet I could chain these together
snow beacon
True and not print("1") or print("2")?

(It evaluates to True sometimes.)

looks a lot nicer too

a lot won't work
the original one (with the ugly parens) works pretty well with chaining
check this out
v1 = "a"
(not v1 == "a" or print("a")) and (not v1 == "b" or print("b")) and print("?")
v1 = "b"
(not v1 == "a" or print("a")) and (not v1 == "b" or print("b")) and print("?")
v1 = "c"
(not v1 == "a" or print("a")) and (not v1 == "b" or print("b")) and print("?")
a
b
c
You can get rid of the not if they evaluate to True.

that's a good point

If you really want to discard a value, you can do (0,func(),)[0].

I'm just being oddly specific about trying to get this to work with any function, when in practicality it doesn't really matter
XD
snow beacon
Or I expect (func(),1)[1] would look better because you can remove the not.
final night
ah, nice
snow beacon
If you do that to both functions, you could tack and None on the end to make the final expression always evaluate to None.

@grave rover shorter -> ENDIAN = ['little','big'][1%memoryview(b'\1\0').cast('h')[0]]
grave rover
wait why not flip the two so you don't have to do 1%
oh wait nvm im dumb
wait yeah you can cast it to b and use ['big','little'][memoryview(b'\1\0').cast('b')[0]]
or wait
nvm I'm dumb
grave rover
yeah I'm not have smart

theres no tutorial on it because its just a bunch of tips and tricks you learn over time

its very stressful trying to get your esoteric code right but when you get it it feels amazing
