you will also neeed to convert this because your two file need it https://github.com/MartinScharrer/crccheck/blob/c2b8f7640358332fab139a2f0c70beb7bc1e89e5/crccheck/base.py#L1

what about executing python code from c#, because what you are asking seems quiet difficult

Core Dream Studios10/30/2022

Yeah my issue is I do not know python enough to convert

Core Dream Studios10/30/2022

I found this site, but the output is sloppy and doesn't even work, probably AI based.: https://pythoncsharp.com/

Core Dream Studios10/30/2022

I could call python from C# but I need all the return values etc.

zonedetec10/30/2022

please then change your post title as "Executing python function and gets their return value" so more people can help you. This is something I've never done but it is definitely possible

Core Dream Studios10/30/2022

Was hoping to port it to native C# and still keep the license under him (did email)

Core Dream Studios10/30/2022

but if needed, will change title

zonedetec10/30/2022

sure

zonedetec10/30/2022

do you need all the python function or just some of them?

Core Dream Studios10/30/2022

well whatever is in the .py's to do all those checks, pretty much

Core Dream Studios10/30/2022

i wish i knew python enough to figure it out 😦

zonedetec10/30/2022

even if you knew python you wouldn't want to convert 2205 python lines into c# I guess

Core Dream Studios10/30/2022

I tried so far:

Core Dream Studios10/30/2022

well via that website converter

Core Dream Studios10/30/2022

but it's a mess so far lol

Core Dream Studios10/30/2022

and nothing works from conversion

zonedetec10/30/2022

yeah try to add this file to https://github.com/MartinScharrer/crccheck/blob/c2b8f7640358332fab139a2f0c70beb7bc1e89e5/crccheck/base.py#L1

there's a problem with that website : because python does not use any type things (ie. x could be a string, then a int, then an array), the website put all variable as "object"

Core Dream Studios10/30/2022

sec

Core Dream Studios10/30/2022

yeah i saw that too

Core Dream Studios10/30/2022

Does this do what all those .py libs do?

Ero10/30/2022

how should i know

Ero10/30/2022

test it

Core Dream Studios10/30/2022

yeah good point XD

Core Dream Studios10/30/2022

thanks

Core Dream Studios10/30/2022

this might just be enough to do it, well minus the checksum part but i can figure it out if i try hard enough. 🙂

Core Dream Studios10/30/2022

question 2

Core Dream Studios10/30/2022

python to C#

Core Dream Studios10/30/2022

since this one has no native C# library, doing by hand:

Core Dream Studios10/30/2022

Converted:

Core Dream Studios10/30/2022

  public static object intersperse(object lst, object item) {
            var result = new List<object> {
                item
            } * (lst.Count * 2 - 1);
            result[0:2:] = lst;
            return result;
        }

Core Dream Studios10/30/2022

What is [0:2:] ?

Core Dream Studios10/30/2022

was in .py too
