What Hacker News says
15 sourcesExactly. I genuinely do not understand how any significant user of python can handle white space delimitation. You cannot copy or paste anything without busywork, your IDE or formatter dare not help you till you resolve the ambiguity.
One day https://github.com/mathialo/bython one day!
In No Semicolons NeededHm, I hadn't actually checked it but also I just saw it on their github issues and some kind soul had even created a logo for bython
although I think its definitely Ai generated but still, it has many people reacting and I think that the community is waiting to be revived lol.

Nothing stops us from forking it either too or bringing the original person if they are still interested too y'know!

5 points · Open discussionbefore judging too hard, this might be a project from a 15yo forking another project that replaces indentation with brackets in python code (https://github.com/mathialo/bython).
bro actually made a meme into reality.
In Python with RizzBecause bython is basically a glorified regular expression search and replace: https://github.com/mathialo/bython/blob/master/bython/parser...
Rather than a real parser. A real parser knows about the context it is in, and as long as the grammar is unambiguous about some character, it can be reused in as many distinct parser constructions as you like. A pure regex-based approach to a first approximation can not.
Whether or not it absolutely can or can't, without "approximation" and with regard to the exact re library in Python, would be something you'd have to work out through tedious effort. Regexes with backtracking can do a lot more than mathematical regexes, as well as all the other elaborations you could use. But even if Python's re can do it, you will be better off with a real parser.
The "correct" solution, since by design Python an
Read the rest
d Bython share the same AST, is to take some existing code that can parse and re-emit Python code without changing it, tweak the incoming grammar to use braces instead, then emit the AST back out as Python. Then you wouldn't have this problem, or the problem with comments referenced in the source code (line 109 of the file I linked, just up a bit), or any of the probably other many little issues that would arise on real code if you tried to put this in real use. The only slight complication I can see is there may be a slight issue with comments around the braces. I'm not sure, and I'm not going to sit here & work it out fully for an HN post.
Also, this is not a criticism of Bython. The author can do as they please with it. If nothing else you can always label this a prototype. Prototyping is good, right? Anyone who was rushing to slam this into production is just gonna learn a real valuable lesson worth its weight in gold, and not Bython's fault.

Behold, bython: https://github.com/mathialo/bython
In Bringing the print statement backI don’t totally mind it. Poor PEP8 implementations can drive me nuts and so can the type of indentation allowed. But otherwise I can get over it.
And then there’s Bython... https://github.com/mathialo/bython
In Python is not a great programming languageI am a novice programmer who started with python and have recently been using javascript, where I use auto-indent-on-save.
Coming back to python is annoying because it's harder to make sure code is at the right indent level than to use { }.
In fact writing this comment inspired me to find this:
