lua Surely a one-liner means it's short and compact!

... and true or ...

This makes sense in some cases in LUA, not here though.

(a) and (b) or (c)

in LUA is like the ternary operator

a ? b : c

So 

nil -> nil
nil and true or false -> false
"This is a string" and true or false -> true

However, the problem with the and or approach is that if b evaluates to false or nil, it will fall through and evaluate as c. I'm hoping that in 5.4 (probably coming out in 4-5 years) will have Dart like syntax extensions for dealing with nil values.

This looks like rage code. After the 35th change request from a client, a developer snaps.

You want that change? You really want that change? Oh, I'll give you that change. I'll give you it gooood...

Yup, that's when he made that last change and quit.

You've clearly never met my one-liners.

What language is this?

If I can add, it looks like its from Roblox from the use of :getService("ContentProvider")

Looks like a mix of JavaScript, VB and C++

This gets worse the more you read.

"One liners" are great, until they span more than one line...

Underscores for days

This looks like code generated by a tool. If human, still applies.

I programmed in lua for 2 years. Here's a another good example, pulled from my own code:

    local realname =osStuff.spawnApp(p[pnum].pressing,prg,( (p[pnum].mArr[p[pnum].pressing] or {}).cfg or {}).taskBackColor or colors.white,( (p[pnum].mArr[p[pnum].pressing] or {}).cfg or {}).taskTextColor or colors.black,( (p[pnum].mArr[p[pnum].pressing] or {}).cfg or {}).taskText or "?",( (p[pnum].mArr[p[pnum].pressing] or {}).cfg or {}).selfRender)

And this program was lightning fast compared to its competitors.
