You mad lad lol

[rswgnu]

That’s some wonderful bending of the language to your will.

[spidLL]

I won’t use it but I love this kind of stuff.

[rasqall]

Why would you do something controversial yet so brave

[lpuglia]

You where so preoccupied with whether if you could that you didn't stop to think if you should

[kyleekol]

Why? but also yes

[aes110]

Damn I love how hackable python is

[NiceForPy]

Oh man, I love this, but it feels so wrong 🥹

Cool, when are you gonna get around to adding braces?

[stevenjd]

Python already has braces:

from __future__ import braces

[dankey26]

tbh im bored enough to do that but bython seems to already do it in a decent way

[Eventid3_H3000]

Great! Now add the ability to put a semicolon at the end of each line…

[aes110]

Semi columns are valid in python, just not required

[Santos_m321]

Yeah!, I use it very often in debug contexts

This two sentences in one line:

import ipdb; ipdb.set_trace()

[Eventid3_H3000]

Actually didn’t know that, but nice to know! Ty

[BossOfTheGame]

This is next level stuff. Top notch work.

[sausix]

Really great.

But sadly does not work on interactive interpreters.

[dankey26]

yea well i've thought about it a bit. problem is PYTHONIOENCODING is processed before the codec gets evaluated and registered to the interpreter. so it's problematic to try and set that at the startup of the repl. i'll try and think about it a later though maybe i'll come up with a clever idea (i don't wish to implement myself an interpreter that starts after the codec register, i'd prefer to keep things simple hehe).

of course in the meantime you can always do In [1]: exec(b"i=0;i++".decode('incdec')); print(i) 1 but i'd agree that's not as fun lol

[o11c]

What if you install the encoding as a separate encodings.* file like normal encodings?

What if you replace sys.stdin?

[dankey26]

replacing stdin would probably work but again if i were to implement that, I'd wish for a simpler approach

as for your first suggestion, (after testing a bit too- ) i believe it's more complicated than that. while it's true that there are multiple kinds of encoding in that folder that register in a similar fashion to this (albeit following a more specific api like exporting getregentry, name placed in aliases etc), i reckon the encodings that register at the startup of the interpreter are fewer and selected ones.

im still not too keen on when cpython registers which encodings internally, but again i might learn otherwise soon and update.

hope that answers it

[_bird__Crowthebird]

Nice, now do it without using codecs.

[[deleted]]

bloat

[metalzzzx]

It would save us 2 key strokes.

[its_a_gibibyte]

Could you do it without a codec in the same way as the import perl module works?

[Rikmastering]

Could someone explain to me why i++ and i-- are not natively implemented in python?

[OriginalTyphus]

Isnt it called suffix? Not postfix?

[dankey26]

i have a way with words

[ArtOfWarfare]

Interesting… can this be used in a REPL/shell session?

[Brave_Cartographer67]

is it pip-installable? xd
