Semicolon

[nightcracker]

Hi all!
To instantly get to the point, is there any use for the semicolon (;)? I know that it kind of "forces" an end of line. But is there any situation it is needed?

Thanks in advance,
Nightcracker

Not in any cases I've had to deal with. Mashed up one liners don't even need semicolons to indicate a new line, but they do help with readability.

Any semicolons you see in Lua code come from authors who either a) have a background in a different coding language which uses semicolons, or b) learned Lua by looking at code written by the authors in a.

Semicolons don't hurt anything - as Katae pointed out, sometimes people use them for readability. But they're 100% not necessary (unless I'm missing something, in which case they'd be 99% not necessary ).

Sometimes you'll which it was enforced however...

/me is confused

What does having a semicolon ( ; ) at the end of a line have to do with your forgetting to separate your vars with a comma?

I use them to condense 2 or 3 short lines into one line -

r = 255
g = 255
b = 255

r = 255; g = 255; b =255

If they had been enforced that would have been a syntax error.

r, g, b = 255, 255, 255

people put ;'s simply because that's their habit and it helps keep them sane when coding in lua then going back and coding in C.

Semicolons seem like such little consolation when curly-braces mean table creation rather than scope and therefore you must use "then" and "end".

I suppose that was not a good example

I still use them to make things condensed where my OCD thinks multiple lines are sticking out like a sore thumb -

macroButton_ShowGrid(self); self.hidegrid = true

The scope and script aspect were the hardest for me to get used to. The endline stuff wasn't too bad, though having gotten used to not using it made function consolidation more annoying. It's a fun language once you get used to it, but moving to and from C-based languages can definitely be confusing.
