Theres a difference between being stagnat at the top of a mountain vs in a ditch at the bottom though.

Wheany: Mar 17, 2006; Spinya^{ha^{ha^haha}ha}ha_{ha_{ha_haha}ha}ha!; Doctor Rope

i made a thing that sends files to an external file hosting service for our client. we agreed that i upload the files to a specific directory and their process takes the files from that directory and moves them to "<numeric id>/Lahetetyt". at some point my code scans every <numeric id>/Lahetetyt directory and reassigns the files in our database to the new path. this has been in production use for almost a year and afaik, it has worked fine.

we got an email saying that it doesn't work. turns out there were a couple of problems:
the file paths are saved in a (mysql) table where the default collation makes a, � ann � equal and there was at least 2 files that had identical file names except the first one used an "�" and the second used an "a" (my guess is that they tried to upload the one with � first and maybe it didn't work, so they renamed the file and uploaded it again). so i had to fix the collation issues there.

the second problem was that at some point the client had changed their file processing so that it moves the files to "<numeric id>/L�hetetyt" instead of "<numeric id>/Lahetetyt". this was only a problem because my code has the Lahetetyt directory hardcoded, it does not actually scan the <numeric id> directories for subdirectories. "L�hetetyt" is of course the correct way of writing the word (it means "sent"), so maybe their coder mistakenly wrote the word correctly during some maintenance.

anyway, this has been today's episode of "fun with diacritics".

lol i'm under no fuckin illusions about that, because here's why i had to look it up

guess what, it's unnecessary pointer math dipshittery are you surprised

C code:

#define GET2(p)  ( (p)+=2, ((p)[-2]<<8) | ((p)[-1]<<0) )

now that I know what comma operator does it's not even special pointer math dipshittery, it's literally "read 2 bytes, advance pointer". gently caress's sake, whoever-wrote-this-15-plus-years-ago! :argh:

c++20 finally took the step of deprecating operator, inside subscript expressions in the hopes that a[1, 2] will someday be able to do something sensible instead

feels like comma came before someone figured out

#define do { ... } while (0)

also gcc and clang have ({ ... }) which is kinda useful

Cool, maybe if we're still alive it will do something useful in c++72: centennial edition.

ocasionally it's useful in some kind of for loop if you want to e.g. keep a low-index and a high-index that you want to update at the same time.
K&R loved these sort of doing-way-too-much-in-the-loop-condition constructs. But it's usually way more readable to just rewrite it as a while loop and do all the special crap on separate lines.

code:

void reversestr(char* str) {
  for (int low = 0, high = strlen(str) - 1; low < high; ++low, --high) {
    swapchars(str, low, high)
  }
}

or you could have something like this, if you have some kinda loop conditional that needs a line or two of setup beforehand but you want to avoid using a mid-loop break for whatever reason.

code:

Thing a;
while (a = GetNextThing(), ThingIsValid(a)) {
  Frobnicate(a);
}

forget you ever learned so

otherwise you might start thinking about operator,() in C++

having dealt with a codebase where it was used, this is not a place of honor

also the comma operator in C�ignoring the C++ operator as overridden�is basically just Lisp progn

The comma operator on its own is ok I guess? Being useful is rare, but there are some places for it.

But did you know that you can overload it? :2bong:
