Schrödinger's boolean

[–] mrkite@programming.dev 28 points 10 months ago (1 children)

Known to cause heisenbugs. They're bugs that disappear when you try to measure them with a debugger or a printf.

[–] jaybone@lemmy.world 16 points 10 months ago

So regular bugs then.

Weird. Booleanish isn't a built-in, I'm pretty sure. I'd like to see the definition.

[–] madkarlsson@beehaw.org 16 points 10 months ago

This looks like javascript so let me guess the typescript definition

any|unknown

this is a joke, please chill

[–] Drama_durch_Lama@feddit.de 25 points 10 months ago (1 children)

That gave me an idea: A variable that is only defined when observed by a debugger, otherwise it's null.

[–] Flipper@feddit.de 9 points 10 months ago

How about an instruction that jumps only when a debugger is attached? Cause that exists.

Call me when defining it a second time makes it guaranteed false again.

HOW?

[–] kubica@kbin.social 0 points 10 months ago (1 children)

Put it in an if-else and it executes both blocks.

[–] theneverfox@pawb.social 0 points 10 months ago (1 children)

Fun fact I learned today - you know how when there's a compound conditional, the interpreter stops once the result is known? (Eg, if the left side of an and is false, it's false so it doesn't bother checking the second condition)

Apparently, visual basic doesn't do this thing every other language I know of does... It might be a debug only thing for the convenience of the depreciated ide I'm forced to use, but I did a null check && called a function on it if it's not null, and it blew up

I pride myself on my ability to change to a new programming language and make progress on day one, but vb is truly the most disgusting POS language I've ever seen. From syntax to jarring inconsistencies in language design, it's just gross

  1. That's behaviour that's just part of language design. If you rely on it you should probably check how the language you're using handles it.

  2. relying on that behaviour sounds a lot like "clever" (read unnecessarily unreadable) code
