How do I get the number of lines from a script source?
I'm developing a plugin that counts the lines in each and every script in a game, but I don't know how to detect a new line. Here's the main code so far:
function getLines()
local count=0
local objectsInGame={Workspace,game.Players,game.Lighting,game.ReplicatedFirst,game.ReplicatedStorage,game.ServerScriptService,game.ServerStorage,game.StarterGui,game.StarterPack,game.StarterPlayer,game.Soundscape,game.HttpService}
for subject=1,#objectsInGame do
for _,v in pairs(objectsInGame[subject]:GetChildren()) do
if v:IsA("Script") or v:IsA("LocalScript") or v:IsA("ModuleScript") then
print("Was a script")
local source=v.Source
--add to line count
end
end
end
return count
end
There are no errors, all of it works fully.

There are a bunch of different ways to accomplish this.
source is just a string, so we're somehow going to count newlines, which are specified by "\n" (the newline character).
Intuitively, a really simple way is to remove all of the newlines and find out how much shorter the string got.
local totalLength = #source
local sourceWithoutNewlines = source:gsub("\n", "")
-- Global substitution of newline with nothing
local lengthWithoutNewlines = #sourceWithoutNewlines
local numberOfNewlines = totalLength - lengthWithoutNewlines
local lineCount = numberOfNewLines + 1
-- 1 line will have no \n so we add one
In fact, gsub will tell us how many things it substituted, so doing the length comparison is actually unnecessary:
local sourceWithoutNewlines, numberOfNewlines = source:gsub("\n", "")
local lineCount = numberOfNewlines + 1

Cool, that's exactly what I needed! Thanks a lot! ChipioIndustries 454 — 10y
