    Whenever the compiler refuses to compile because of an unused var:

    Hey Jeff, we know the variable is unused. WE CAN SEE THE SQUIGGLE

      Not a go dev. Is it really preventing compilation or is it just some hardened linting rules? Most languages can prevent compile on those errors if tweaked, but that seems bad if it’s not a warning

        Yes, and it fucking sucks. It’s a great thing to lint for but it makes debugging such a pain - commenting out an irrelevant block to focus your debugging will sometimes break your ability to compile… it’s extremely jarring.

          Making a variable just to hold a debug value to look at with a breakpoint, but Go says no.

          This is why many languages have errors and warnings as separate things. Errors for things that for sure prevent the program from working, and warnings for things that are probably wrong but don’t prevent things from working. If you have a setting to then treat warnings as errors (like for CI checks), then you get all the guarantees and none of the frustration.

          Have they given an explanation as to why that is? I mean why make it a fatal error that prevents compilation, when you could make it a warning and have the compiler simply skip it?

            Its an effort to keep large code bases clean. I think they should allow them when running go run but not when building.

              I can see the sentiment here… Going through 100 clippy warning on Rust is just not fun… I know there’s the good old clippy --fix but I’m paranoid it breaks my code accidentally.

              Could probably have a compromise like 5 unused variables and your code don’t compile

                Automated tests and version control should prevent that from being a problem, I imagine.

              I totally agree that it’s really annoying when debugging, but go run literally builds then executes. I think what they should do is add a build flag. So debug builds can pass that flag to get the builder to shut up, and leave it enabled for production builds.

              Or, you know, treat it as a warning like literally every other language. There’s absolutely no good reason for it to prevent a build outright, but then again, there’s not really good reasons for many of the decisions behind go.

            Keep in mind that this is the same language that prefers function names ToBeLikeThis(), and the reason is that it looks different than Java.

                There’s two types of programming languages, the ones people complain about and the ones nobody uses. Go is still my most productive language and is killer for building webservers. I basically use it as a scripting language since it’s so fast to write, compile, and execute.

          Whoah, that seems like you’d flesh out code elsewhere, you know when you throw stuff together to make it work, and then fix it up to standards.

          Feels like you should have to make git commits perfectly well before being able to compile…

          Put that overwhelmingly intrusive thing in a hook checking out your commits instead (when you push your branch ofc).

          What reason is there for this when the compiler could just optimize that variable out of existence? This feels like the most hand holdy annoying “feature” unless I’m missing something.

            Cleaner code. That’s all.

            If you need to take variable you don’t use for some reason (like it’s a function arg that has to follow an interface, but it doesn’t need a specific parameter in this case), then you can prefix it with an underscore.

              That’s what warnings are for and -werror for production builds in literally any other language. This has been a solved problem for a very long time.

                Sure. Tell that to the Go devs.

                If the language weren’t pushed by Google, nobody would pay it any attention. It’s yet another attempt to “do C right” and it makes some odd choices in the attempt.

        I don’t think its inherently bad but it feels jarring when the language allows you reference nill pointers. It’s so effective in its hand holding otherwise that blowing things up should not be so easy.
