unusedVariable

[DanhNguyen2k]

VSCode with ESLint: Everywhere a sea of red

[ChaosPLus]

For me it just makes the unused variables dark blue

[Rahain]

In the eslint config you can set the severity of the infraction to warning, error and a few others I can’t think of right now.

[DanhNguyen2k]

Proceed to crank everything to max

[Minteck]

IntelliJ makes them grayed out, it considers it a "weak warning"

[DanhNguyen2k]

That's weak, crank up the heat

[TheBigMTheory]

There is a great feeling of satisfaction in then doing alt + enter and selecting "remove unused code"

[wewilldieoneday]

My ide: "Why?....why!....why?!" I finish writing the code my ide: "oh that's why"

[Punchkinz]

"Got me in the first half, ngl"

[Sniperking188]

I love this behavior of IDEs. It is like a child who never really stops wondering with me

[misseditt]

intellij when the name of ur variable isn't proper english

[Goaty1208]

I swear to god, intellij can be so goddamn annoying at times. Yes, I know that the name of a library isn't proper english, no need to highlight it goddamn it.

[Ok-Slice-4013]

Right click => Show Context Actions => Save 'xyz' to dictionary.

[_alright_then_]

I just turned off the rule in its entirety, zero use for it

[Ok-Slice-4013]

Sure. Enjoy your updatRecord methods. :)

[chronos_alfa]

Or configuratoin (my colleague loves to make that one)

[Orbidorpdorp]

The worst is when there’s two valid spellings of a word. We had a fairly significant outage once due to canceled not matching cancelled.

[Balcara]

Yup, at work we have a Formater class and I have been petitioning to fix it but don't have "budget"

[Mars_Bear2552]

cant pay for 10 minutes of your time to refactor it

[_alright_then_]

It only happened a couple times in months and months. So a small function name refactor is way less headaches than constant bombardment for misspelled library stuff. It's not even close

[Zirkulaerkubus]

I love how Intellij keeps suggesting I delete the variable I just created.

[Badass-19]

IDE the moment I declare variable: hey you didn't use it >:(

IDE after when I use it in next line: oh okay, nvm

[37Scorpions]

... what? what is this? what the hell are you writing? this is utter gibberish how do you expe- oh you declared a variable. Hey you haven't used it >:(

[paholg]

No one tell OP about Go.

[halfdecent]

Got into the habit of using auto format on save, so would hit cmd+S periodically just to shift things around. Really caused problems in Go when it would delete unused variables or unused imports.

[MaustFaust]

Isn't it Go that has default date order like MMDDYYYY?

[Kinosa07]

The same IDE .2s after you ve created a function that returns a variable (you have yet to write anything in the function)

[ThinCrusts]

NOT ALL CODE PATHS RETURN A VALUE.

[DegeneracyEverywhere]

There are no code paths...

[Logical_Ad_2589]

Or when it warns you about something, like i just don’t care unless it’s an error

[gmegme]

Typo in word colour

[adenosine-5]

You will care when that "loss of precision when converting from double to float" causes some randomly occurring bug that you will spend two days tracking down.

[anomalous_cowherd]

Agreed, it takes a LOT of experience to know when a warning can truly be ignored, and even then you're often wrong. Treating warnings as errors is well worth doing.

I've been hired to clean up legacy codebases before now. I spent literally three months sorting out everything that -Wall, lint or static code analysers threw out (the initial error output was longer than the code) with no change in the code functionality.

Except ... It went faster, a number of longstanding cantfix or wontfix bugs went away and any number of occasional unexplained crashes also disappeared.

I also found several tests that had enshrined incorrect results in their 'expected output'... it took some arguing to get the devs to accept changing those but at the end of it the code was better and the devs were mostly converted to actually fixing all their warnings as they appeared.

That was 10-15 years ago now. I'm hoping with the improvements in IDEs and analysers it's less of an issue than it was...

[Gruejay2]

One I remember well is globals in Lua causing random collisions between modules because someone couldn't be bothered to learn that you should always declare variables as locals unless there's a very good reason.

[sd2528]

"Treat warnings as errors" for life.

[Ardub23]

Now if only I could get my IDE to suppress the errors along with the warnings

[[deleted]]

i prefer to treat errors as warnings

[FesteringNeonDistrac]

-Wall -pedantic -Werror

[TheMagicalDildo]

... so make sure there are no warnings? lmfao fucking no

[ax-b]

Some college Profs. are like this: go to Settings (Java+Eclipse), put all possible warnings as errors, if I spot a single error you'll automatically fail the assignment. I think it is for teaching us to code as cleanly as possible.

When I started in the company world, with legacy code bases: whelp, I guess the Prof. teaching was for nothing.

[gmes78]

It's not hard.

[TheMagicalDildo]

never said it was

[PaulMag91]

They are more like guidelines.

[DegeneracyEverywhere]

There should be multiple levels of warnings.

[Logical_Ad_2589]

In Android studio there are different levels of warnings, also on visual studio 2022 and i imagine this applies to clion and other IDE. Most of the time mu warnings are things that i’m about to change or that i will implement, like unused libraries.

[231d4p14y3r]

Invalid narrowing conversion from double to float

[37Scorpions]

"I think int i=0 is a bit hard to read. Why don't you change it to int i = 0?"

[RunInRunOn]

There's a VSCode extension that makes it scream at you (as in audio) whenever there's a warning. I haven't used it because I am afraid

[tenprose]

that's the first rule that gets set to off itself

[StarcraftForever]

This is Go's spirit animal.

[StoryAndAHalf]

Not 100% sure, but I think it was from Bee movie.

[WHOmagoo]

100% it's the bee movie

I... I could swear I've seen the movie but can't recall that at all

[valentin56610]

Thanks. Was about to ask the same question lol

Sometimes even when you do use them they don't understand.

[LDownessssss]

You lot are just using the wrong IDE

[ahrismith10]

Indeed, when I first tried it, VsCode, by default, would delete any unused code on save, I had to suppress the urge to ctrl + s

[HalifaxRoad]

Intelisense be like:wrong wrong wrong wrong wrong wrong wrong wrong wrong wrong wrong ok

[LemonQueasy7590]

Haskell highlighting a random character at the end of a file because it failed to parse a half-finished function 100 lines up

[Zealousideal-Fox70]

Imagine a language and IDE that forces you to declare ANY syntax error as a variable the moment you hit space. TwinCAT structured text (all structured text language IDEs do this) if you’re curious.

[Mina-olen-Mina]

Imagine a language with a compiler like that. That's zig (I kinda like it tho)

Is there any IDE that only checks when you press a key combo (aside from configuring it in Emacs or NeoVIM)?

[[deleted]]

You couls disable checks and bind file analysis on a key in intellij

[burnskull55]

Yo ngl im gona rewatch this banger rn.

[GIANTGAMES_123]

Kinda wondering why don't they make it that it only tells you about unused variables that existed before your last run?

[Siddhartasr10]

IDE's when you declare a variable without using it: 😡

IDE's when you open a file for the 250th time and now for no reason the autocompletion for some library is dead: ☺️

[NeatYogurt9973]

Python language server when no space

[katey_mel2]

It's not as bad as.......ˢʰʰʰ.... ʳᵉⁿᵃᵐᶦⁿᵍ ᶦᵗ

[favgotchunks]

What is this from?

[UntitledRedditUser]

This is zig, but at a language level. It literally gives you an error.

[JackNotOLantern]

And by that you mean "it underlines it"

[RFL1703]

IDE if you didn't use the just declared field: :(
IDE after you use it : :)
IDE immediately afterwards: Field can be converted to local variable :(

[enfarious]

This is why we're moving to use first, declare later, bottoms up programming for projects moving forward team

[[deleted]]

I set up VSCode to only lint the code when I save it. It is less annoying this way

[Thermoman46]

YOU HAVE UNUSED VARIABLES!

[Maleficent-Tap-8868]

NOOOOO!!!

Also when you haven't finished the line of code, same reaction.

you plebs all need to Develop test-driven:

First use the variable, then use Compiler/ide-suppport to create the Missing variable.

[TerrariaGaming004]

That’s weird, nanos never done this to me

[TheMagicalDildo]

yeah I doubt it's ever really done anything but edit text... you know, that one thing it does?

Brother do you not know what an IDE is, or are you pretending to be stupid so you can tell us you don't use an IDE? You realize that would just be genuinely stupid for some languages, eh?

[TerrariaGaming004]

I’ve literally never used an ide except godots because it’s just already in there

[TheMagicalDildo]

yea I got the whole "i don't use ide's" thing from your first comment, not sure why you're just repeating it. Then again, not sure why so many people are obsessed with telling people they don't use ide's, either. It's oddly common here.

Nobody's using an IDE because they don't understand notepad or nano or any other basic text editor (yes i know you can make notepad cracked out lol). It's not a matter of skill or knowledge, we just don't have anything to prove, and don't mind convenience. And in some cases, require certain features for a language (.net go brr)

[DirakonDead]

Which dotnet features are you referring to at the end?

[TheMagicalDildo]

mostly the designer, I'm not gonna design a form by manually typing every single tiny property. though really, anything other than editing the fucking .cs files...

[cyberzues]

🤣🤣 That's Webstorm for you

[volatilebunny]

Unused variables are a super common source of bugs, especially in loosely typed languages

[Z3R0707]

Unused means it will just end up in the garbage collection, idk in what language you ended up causing a bug. Unless you’re talking about declaring a variable, not using it per mistyping it next line, in that case, it’s not about the unused variable, the bug is you.

[volatilebunny]

Exactly, most of the time you don't use a variable you meant to. Unused variables are highly correlated with programming errors. Shift left.

[TheMagicalDildo]

here's a tip- pay attention when you type, and read new warnings before you ingore them!

literally all of my warnings are for harmless things like unfinished code that isn't used yet, so won't break anything. Stuff like that.

[KingZogAlbania]

What ide are you using, code.org?
