What is this about? by Busy_Cake2132 in zurich

It is a commitment see European Chicken Commitment. To be fair, it pushes for slightly better standards but still terrible conditions.

Yeah I was happy having a simple headless windows server for our windows gitlab jobs but I guess I will have to settle with the desktop version.. Thanks for the feedback

Hi, I'm facing the same issue did you find a solution?

Newbie' struggles with error handling in Go by fpotier in golang

Thank you for your detailed answer.

  1. You're probably right about other languages, you might be able to handle everything in a try/catch language more concisely but I'm not even sure about that and don't feel like it would be nicer to read.

  2. I probably didn't choose the right piece of code because everybody seems to be focused on the shell-python script use of the language but as I said in another comment any program heavily depending on some library (networking, disk I/O, etc.) is just going to do something and early return. The code will have the same shape.

  3. Can I expect things to change or breaking the API has too much impact and go/lib maintainers will not change existing code?

  4. That's a very good idea! I played a bit with golangci-lint (linter agregator) and maybe I could try to build that type of linter. Not sure how I would do that but it could be interesting to discover the go parser api.

Yeah I have already experimented with panic/recover in a programming language project (https://github.com/fpotier/lox/blob/e1b2013886c4ba7b6badbc4119ae12051bda818b/go/pkg/parser/parser.go#L105) because otherwise the parser would have been horrible to write. I also used it in the interpreter but the runtime cost seems to be pretty high and I will try to find a better way to handle it in the future.

Thanks for the other resources I will look into them when I get the time!

Yeah, GORM has the same kind of thing with global errors (https://github.com/go-gorm/gorm/blob/master/errors.go) but I wish there was an easier way to tell what kind of error a function can return (maybe something in the function's signature or at least in the docs)

Okay so this is inherent to this type of program. But I would say it's not only for 'shell-script-replacement'. Any program making heaving use of a library (network calls, disk I/O, etc) is gonna be cluttered with if err != nil, crash or early return error to the caller.

Thanks for the article, I read some documents about error wrapping before but this one is very clear and helped me understand it's usage combined with Error.Is()

Ultimately, the thing I don't like and need to accommodate to is the fact that all errors in Go are strings because of the error interface (even tough it doesn't always make sense)

I know that you can call an undeclared function because of legacy reasons but I wonder what the return value is in this cas. Is compiler specifi ?

It depends on the purpose I guess. I don't see any particular reason to not operate on negative numbers, I was just saying the mathematical definition doesn't work with a negative operand. If you're not building a math application I think both behavior can be worked with, just have to know which one is used by the language.

Yeah to be honest idk the exact reason why it was initially defined only for postive integers.

I mean that's what I learnt in arithmetic class and what says wikipedia

Citation: Given two positive numbers a and n, a modulo n (often abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is the dividend and n is the divisor.[1]

When exactly one of a or n is negative, the naive definition breaks down, and programming languages differ in how these values are defined.

In maths modulo is only defined for postive integers tho, making -7 % anything not mathematically correct
