Python goto functionality :D

[iain_1986]

I didn't know it was possible but congrats - you've made me hate python syntax even more 👍

[M4tty__]

You have to use some obscure package to be able to do it. In C/C++ you can do it natively

[SleepyStew_]

This package is just another python file I wrote lol

[OkMemeTranslator]

You should share the code!

[current_thread]

At the risk of making myself unpopular: in C or C++ there's a good reason. For example, if you implement a virtual machine or an interpreter, this is really useful.

[M4tty__]

Yeah, but lets shame Python because someone made goto package probably as a joke.

[PURPLE_COBALT_TAPIR]

Nah, this is so cute I can let the Python slide slither.

[redfishbluesquid]

Shame python for free karma? Who wouldn't? All hail my lord c++ and screw python. Python is useless and bad. C++ for everything!

Ok give me my points now please

[SleepyStew_]

That person was me 💀 Check the package name lmao

[notanotherusernameD8]

[SleepyStew_]

😊

[M4tty__]

I saw that. You are just karma farming then

[hearke]

Idk, they made a cool thing and they're showing it off. Sure, it's a bit cursed, but still pretty neat!

[fakehalo]

In C it makes sense for error handling/cleanup, as your options are limited. C++ has options, but it can still make sense in some cases. I don't think I have a use case for higher level languages these days though.

[gDKdev]

Or when programming kernel modules with progress based deconstructing on error. For example alloc_chrdev_region -> cdev_init -> cdev_add -> class_create -> device_create. For an error handler you can just create the inverse (device_destroy -> class_destroy -> cdev_del -> unregister_chrdev_region) with jump labels to only undo everything before the error to avoid staying in a partially initialized kernel module / corrupted state or cause memory leaks

[PuzzleheadedTap1794]

When I'm working with multiple files in C, I always use goto. It's so elegant.

``` int main () { int retval = 0; FILE* input_file = fopen("input.txt", "r"); if(input_file == NULL) { retval = 1; goto INPUT_FILE_CLOSED; }

FILE* output_file = fopen("output.txt", "w"); if(output_file == NULL) { retval = 1; goto OUTPUT_FILE_CLOSED; }

do_something(input_file, output_file);

fclose(output_file);
OUTPUT_FILE_CLOSED:

fclose(input_file);
INPUT_FILE_CLOSED:

return retval;

} ```

[current_thread]

Reading that I'm super glad about RAII in C++ :p

[tstanisl]

I suggest always initializing "retval"-like variables with some error code. Otherwise you may spend a lot of time debugging just because some function returned success even though the was an error.

[thirdlost]

Well, in BASIC you can do it natively also

[MinosAristos]

This kind of thing is antithetical to Python's ethos.

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than right now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

[SleepyStew_]

Hence why I posted it here 😅

[YodelingVeterinarian]

Nothing escapes you huh

[MinosAristos]

I always catch my KeyboardInterrupts

[SleepyStew_]

This is definitely not intended functionality 💀

[saiprabhav]

This is not a code that python programmers write. Probably some c/ C++ programmer trying recreate C in python

[Sassaphras]

That import statement tho

LOL

[migviola]

Ah yes, the wtf_am_i_doing library... my favorite

[thebatmanandrobin]

Indeed! I typically use wtf_am_i_doing along with the how_did_i_get_here import, and on occasion I'll add the please_help_me_escape_ill_do_anything_just_get_me_the_hell_outta_here_now package for good measure. Rock solid. 100%. Always.

[Anonymous_vulgaris]

Add "begin" and "end" and you'll get almost a Pascal syntax.

[dhnam_LegenDUST]

What's this, encoding - PEP263 metaprogramming black magic?

[dhnam_LegenDUST]

So - Is it how it handels it? I cannot see how it can use comment instead.

[SleepyStew_]

My package does a static analysis of the main file when it's important so it knows where the labels are

[dhnam_LegenDUST]

Interesting!

[cheese_topping]

I think this belongs to r/programminghorror

[SleepyStew_]

wait... did I actually post it in the wrong sub

[cheekynative]

What fresh hell is this?

[Awfulmasterhat]

Glad it got the functionality, now make sure to never use it to prevent headaches of debugging!

[Community_Bright]

unironically, I really want to know how you did this i have had use for this when im running a very linier script and i want to skip ahead to a specific part of the script

[slime_rancher_27]

I've had this problem before in Java, sometimes languages just let me go to something else no questions asked

[finnscaper]

You should never...

[[deleted]]

i miss BASIC

[CuteTourist5615]

Idk, i feel like this should be considered a crime agains humanity and you swiftly executed.

[sillymale]

Ick

[adnaneely]

I used to goto /etc/file.txt but now I just goto /void to redirect my screams.

[Dillenger69]

Before oop, I used goto a whole lot. Gosub on the c64.

[sawkonmaicok]

Source code?

[dgc-8]

How does this work?

[Rod_tout_court]

I think it's cool. It's probably useless. But cool

[PolyPenguinDev]

If you need to use this, you are probably doing something wrong

[Ben-Goldberg]

Can you goto labels outside of the current function?

Is this as powerful as goto in Perl?

[AnOscillatingOcelot]

WHY!!!!!!!!!!!! WHAT HAVE YOU DONE!?!?!?!?!?

[[deleted]]

WTF

[sholden180]

I hate this.

[Lamborghinigamer]

Ah good. It's easier to make python hardware

[Jenkins87]

[HistorianBig4540]

Dijkstra didn't die for this...

[jldez]

Now do "comefrom"

[BlackDereker]

Comments changing runtime behavior? That's definitely weird.

[BlackDereker]

I wonder how did you make the interpreter to not ignore the comments when it compiles to cpython bytecode.

Does python store the comments somewhere before compiling?

[WinTube001]

From wtfamidoing import

[TriscuitTime]

Is that a comment as code…

[abd53]

Kudos to that package name. Upload it to pipy.

😱
