for i = 1, 10 do -- Loop 1.
for ii = 1, 5 do -- Loop 2.
break 1 -- This will break from Loop 2.
break 2 -- This will break from Loop 1.
end
end
::outer:: for i = 1, 10 do
::inner:: for ii = 1, 5 do
break inner
break outer
end
endIf you would do it the other way around, and then if you would add another for loop around the others, the breaks will break. You wouldn't expect that if you're modifying this code without looking at the current breaks or knowing about the break behavior.
If you however move the break statements inside a new for loop, at the most inner level, it would seem obvious that you have to update the break numbers.
local stop = false
for i = 1, 10 do -- outer loop
if stop then break end
for j = 1, 5 do -- inner loop
break -- to break from inner loop
stop = true; break -- to break from outer loop
end
end
The reason one might find this cumbersome or problematic, is in the case of very large numbers of lines of code - sure, your example is visible and somewhat readable (arguable) in its current form - but tell me you won't have issues when the loop is 80 or 100 lines of code, and you need to add another inner loop as part of the development process.
Are you now going to go through and be sure all your breaks are numbered properly? Are you really, though?
Better, imho, would have been to introduce labels and "break <label>", but even that is going to cause more headaches than its worth.
Ultimately, one shouldn't write such horrid code anyway.
"Pluto aspires to be a version of Lua with a larger feature-set, that is all. Pluto is not a Lua-killer, an attempted successor, or any of that. Many people (rightly so) love Lua precisely because of the design philosophy. And fundamentally, Pluto is a major deviation from Lua's design philosophy. Some may prefer this, some may not."https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V...
