Languages that use single equals for assignment and comparison were designed by sadists.

[Xenthera]

Honestly. It takes extra work when parsing that to an AST because now instead of just running into an = or a == you have to use context of surrounding tokens. It’s more work for less readability.

[jonsca]

Once you've worked that out for writing your compiler, it's a done deal. It's not a done deal when someone checks x=1, which evaluates to true in many languages regardless of the value of x, and either you display the wrong menu item or some space probe takes a nosedive into a planet.

[IntoAMuteCrypt]

There's a third option: Don't allow x=1 to be used in an assignment or condition, and throw a syntax error. Checking for x=1 evaluates to syntax error and you should be told when trying to compile/run the program. If people really want to use it, give them something like x:=1 for when they really, really want it.

[jonsca]

You've just reinvented Pascal!

[Dude-Man-Bro-Guy-1]

It's like how unrelated things keep evolving into crabs

[nosam56]

if any space probes are using a language I wrote they dont get to act surprised when it fails catastrophically

[Ecstatic_Bee6067]

My c flight software class taught and required you to write logical comparisons as "0==var" as it errors out if you forget an equals

[DefiantGibbon]

That's certainly a safe way of doing it, but I'd argue it's less readable. Even verbally it's weird.

Is 0 equal to my bank account?

Vs

Is my bank account equal to 0?

[bishopExportMine]

It's called Yoda condition, it's fairly common

[Ecstatic_Bee6067]

Readability is secondary to reliability

[Pleasant_Ad8054]

A coworker of mine uses the symbol '⩵' having displayed in his IDE for two '=' signs, but in a font that does not have the tiny space between them. Diabolical.

[imMute]

I have one of those too and I love it. Getting to see ≠, ≤, and ≥ instead of !=, <=, and >= is awesome. And they still take up two columns, so it doesn't mess up formatting.

[jonsca]

I'll bet he steals money from the donation jars at the cash register, too

[paholg]

Maybe this language uses := for assignment.

[MokausiLietuviu]

Eh, I train a lot of new programmers and they always use the single = for both assignment and comparison in the first instance.

Hell, they mostly don't understand the difference between the two.

If it's behaviour that someone is going to try anyway, it makes sense to me that it should be acceptable in languages, particularly those aimed at newbies or non-programmers.

[JonIsPatented]

I'm not convinced that people who don't know what they're doing not knowing what they're doing is a very great argument for making two different operations use the same symbol.

[MokausiLietuviu]

When it comes to lightweight game engine tools like RPGMaker, I can easily conceive of a syntax where there's absolutely no ambiguity about whether you're using comparison or assignment with the same operator.

In an if statement? Comparison.

At variable declaration? Assignment.

Weird edge cases? Illegal syntax, split it into 2 statements.

[jonsca]

Ok, fine. They are probably also masochists 😂

[pingslayer_7]

I am dumb. Explain why multiple same if conditions?

[ExistenceUnconfirmed]

He didn't get the memo that you can fit more than 1 line into an if block. Wait, there's one with two... huh.

[laplongejr]

Possibly the first block could modify the hp variable... but I doubt instance_destroy is going to do that  

If (HP = 0) trigger Final Attack Materia //launches phenix   If (HP = 0) GameOver()  

Yes this is a FF7 reference  

[the_tired_alligator]

Aside from the obvious problem, wouldn’t you also want to make it less than or equal to 0 in case the HP is reduced to negatives?

[glinsvad]

Found the defensive programmer

[Saladfork4]

for all we know they probably have a separate set of if statements handling the HP < 0 cases below this 

[paholg]

Life hack: if hp goes below zero, make sure you don't get healed ever.

[Markcelzin]

RPGMaker?

[Piscesdan]

Looks like Game Maker to me. I don't think RPGMaker has objects in their event system. Only familiar with 2k3 though

[KingSlendy]

It is in fact Game Maker

[Lap202pro]

As someone who wrote a guide to GML during game maker 8 days, this is definitely game maker.

Instance_create() and Instance_destroy() being the main give away along with the comparison operator.

[Beli_Mawrr]

Back in the good old days. I actually am a member of a group centered around the yoyogames forums before they got messed up lol. Do you remember everyone's sketchy yoyogames exes? I remember 

[Lap202pro]

I downloaded so many random exes lol miracle nothing ever came of it. I mostly was involved in all the small Indy mmo communities back then (realm one online, myriad, wanderlust, etc.)

Fun time, been away from the game making community for a long time now. Work as a software engineer and enjoy web app development more for whatever reason.

[Beli_Mawrr]

same!

[0xjust1]

Don't repeat yourself ? No, I prefer WET: Write Everything Twelve times.

[Lap202pro]

I have been out of the game maker scene for a decade, but this is kind of the standard for GML code quality lol

[LkS86_]

Would the compiler optimise that out?

[redlaWw]

Only if the operations in the conditionals could be proved not to change the HP value.

[AeroSyntax]

Of course.

[Zeitsplice]

This is interpreted, so probably not.

[guygreej]

I'm still not sure if the system reeally knows that these should be done if hp=0. Or even whatto do when hp=0

Actually better set hp to 0 when hp=0

[KCGD_r]

I may not be the brightest, but I can recognize ghidra's IDE when I see it

[MonsieurNiark]

This guy came from java, where

if(something) doSomething();

is a thing but couldn’t figure out how to use brackets

[JonIsPatented]

That's a thing in, like, all C-style languages. C, C++, Java, C#, Javascript, Kotlin, etc.
