I propose a new, more threatening kind of control flow.

do {
  /* something */
} or else {
  /* you don't want to find out */
}

Some C++ style guides suggest the following naming convention for functions that crash on any error

OpenFileOrDie()
[-] xmunk@sh.itjust.works 26 points 9 months ago

PHP has the always wonderful (and perfectly functional) syntax of

logUserIn() or die();

Or Perl

[-] frezik@midwest.social 10 points 9 months ago* (last edited 9 months ago)

Perl also has unless() for the very purpose in OP, which is a more sensible choice.

Oh, and if you need to reinforce your belief that Perl is a mess, the single-quote character can be used as a package separator instead of "::". This was set in the 90s when nobody was quite sure of the right syntax for package separators, so it borrowed "::" from C++ and the single quote from Ada (I think).

That means the ifn't() in OP can be interpreted as calling the t() function on the ifn package.

The "::" separator is vastly preferred, though. Single quotes run havoc on syntax highlighting text editors (since they can also be used for strings). About the only time I've seen it used is a joke module, Acme::don't.

Where do you think PHP stole it from?

[-] Kissaki@programming.dev 10 points 9 months ago

Personally, I like to call catched exception variables up, so for a rethrow I can throw up;.

[-] TwilightKiddy@programming.dev 2 points 9 months ago

Except rethrowing an exception in C# is just throw;, anything else is a crime against the person who reads your stacktraces.

[-] MonkderZweite@feddit.ch 4 points 9 months ago

I mean, it makes sense to call ComplainToErrorAndExit just 'die', no?

[-] Vorthas@programming.dev 4 points 9 months ago

One of the modules in a project I'm working on is called VulkanOrDie which always makes me crack up when I see it in the compilation messages.

[-] OpenStars@startrek.website 3 points 9 months ago

It's funnier when you try to SysCallAndDie() :-P

(that's a real thing in perl btw - I guess that function didn't get the memo)

[-] yum13241@lemm.ee 1 points 9 months ago

Now what about GZDoom's GoAwayAndDie();?

[-] Strawberry@lemmy.blahaj.zone 41 points 9 months ago

this is just a menacing try/catch!

[-] moody 23 points 9 months ago

It_would_be_a_shame_if(condition)

[-] Mesa@programming.dev 9 points 9 months ago

The better try-catch. More intuitive if you ask me.

[-] jadelord@discuss.tchncs.de 7 points 9 months ago

It exists, kind of. Python has this construct

for item in iterable:
    ...
else:
     ...

which always puzzles me, since it depends on a break statement execution. I always have to look it up when the else block is executed.

You just made me a offer I can't refuse. I go now to sleep with the fishes...
