Wouldn't most development programs tell them the syntax error on the line and column where you replaced the semicolon

This wouldn't work

[-] [email protected] 78 points 1 month ago* (last edited 1 month ago)

VSCode will add a yellow box around the character and tell you it's an uncommon glyph.

To note, this came about because it could be valid code and it's a security risk from copy/pasting malicious code. See:

Just tested in the console, it gives an illegal character error and gives you the line number.

[-] [email protected] 16 points 1 month ago

It would work for someone just starting and not knowing good tooling yet. However, the compiler should also tell you where to look and give you the area to look at as well. It'll be less clear than an IDE, though.

[-] [email protected] 3 points 1 month ago* (last edited 1 month ago)

Yeah, doing something similar with brackets would be much more effective since that usually doesn't give a line number. Is there a unicode clone of )?

[-] [email protected] 2 points 1 month ago

Yup. It's as if we're assuming this friend is coding inside Notepad.

[-] [email protected] 72 points 1 month ago

Why, of all possible languages, would you suggest this for Javascript where semicolons are not mandatory

[-] [email protected] 22 points 1 month ago

Not only that, the interpreter will point directly to the line of code and possibly to the exact character that is the problem. Any programmer worth anything would find the issue or, worst case, retype the line of code and have the problem fixed rather quickly. “Illegal character” is a pretty easy error to diagnose.

But…I still chuckled a little at the intent of the joke. I’m sure there are better pranks one could come up with, though.

Even better would be to remap their keyboard's semicolon key to that symbol

Before I read this comment I believed the concept of hell was immoral.

[-] [email protected] 5 points 1 month ago

We all have the one friend or coworker..

[-] [email protected] 12 points 1 month ago

you are a criminal.

[-] [email protected] 31 points 1 month ago

Meanwhile in VS Code: hey, I see this Unicode symbol that's confused for this expected symbol, would you like to replace it?

[-] [email protected] 24 points 1 month ago

Maybe if you're "coding" in notepad

[-] [email protected] 5 points 1 month ago

I had a friend who was a compsci minor who did almost the entirety of said minor on a really old chromebook. They did everything on a basic text editor. You would be surprised

[-] [email protected] 21 points 1 month ago

MSVC supports unicode. In C or C++, you could try:

#define ; ;

Second one is the greek semicolon but the client I'm using may strip it out. I'm too lazy to try.

[-] [email protected] 3 points 1 month ago

Running #define ; anything yields error: macro names must be identifiers for both C and C++ in an online compiler. So I don't think the compiler will let you redefine the semicolon.

[-] [email protected] 3 points 1 month ago

Haha. Thanks for checking. Given the C pre-processor, I'm sure there's a way to maliciously bork it if someone sets their mind to it.

[-] [email protected] 2 points 1 month ago* (last edited 1 month ago)

Well I just tried #define int void in C and C++ before a "hello world" program. C++ catches it because main() has to be an int, but C doesn't care. I think it is because C just treats main() as an int by default; older books on C don't even include the "int" part of "int main()" because it's not strictly necessary.

#define int void replaces all ints with type void, which is typically used to write functions with no return value.

[-] [email protected] 1 points 1 month ago

I'm not sure but I think the second one looks just a tiny bit different, so it should have worked.

BOM U+FEFF is another fun one, most editors won't show it but it can cause errors like when I found one in a SQL script that was combined from existing utf-8 files together with cat. You'll see it in a hex editor or in notepad I think it just made the rest of the line italic.

[-] [email protected] 21 points 1 month ago

That's too evil. At my work people like to put a tape under someone's mouse and it can be pretty funny.

[-] [email protected] 7 points 1 month ago* (last edited 1 month ago)

Some hairs under the lens, it gives some funny erratic moves of the pointer.

[-] [email protected] 10 points 1 month ago
[-] [email protected] 5 points 1 month ago

It's ok, someone either put a hair under his 'e' key, or remapped it so that it randomly spits out ' instead.

[-] [email protected] 7 points 1 month ago

The funny erratic movement can keep your work pc from locking up while you do nothing. It's win win.

[-] [email protected] 2 points 1 month ago

I just had this happen to me

I pulled a literal ball of pet fur out of the optical sensor

[-] [email protected] 1 points 1 month ago

If you get a post-it just right halfway over the lens, the mouse will only move in one direction!

[-] [email protected] 12 points 1 month ago

Wanted to use this to prank a colleague but SQL server accepts that as well lol

[-] [email protected] 9 points 1 month ago

Hah. Try it on my version controlled project!

[-] [email protected] 5 points 1 month ago* (last edited 1 month ago)

What? Remapping your keyboard? Well, there are worst jokes, I still remember that time when the first PCs appeared and you could try them in shopping centers. They quickly stopped doing this, because some went into the BIOS and disabled the keyboard or worse, the screen, Hail Satan. Good ol' times 😏

[-] [email protected] 2 points 1 month ago

No I mean the code is on a git repository so you see unsaved changes

[-] [email protected] 3 points 1 month ago

When your keyboard is remapped, you commit those changes yourself.

[-] [email protected] 4 points 1 month ago

Replace all

Rust doesn't let you do this. Crab stays winning.
