Removing comments from a script?
How would you go about removing comments from this
local scr = [[ local t = "hello world" -- cool local f = "world hello" -- removing comments ]] print(scr) --outcome (supposed to be) local t = "hello world"local f = "worldhello" instead of //--\\ local t = "hello world" -- cool local f = "world hello" -- removing comments
I tried using string.gsub but also failed, also couldn't find any articles to help me
people are saying this is a solution, but I'm trying to make this
comment_symbols = "--" s1 = [[ "cool" -- lol "man" ]] print ( string.match( s1, "[^"..comment_symbols.."]+" ) ) -- outputs cool
im trying to make this output "cool man" instead of just "cool"

Are you talking about the comments highlighted in green or variables? DesignerOfGames -7 — 4y

I think ctrl + f can find and replace stuff in a script. So just put in -- or [[/]] and replace it with nothing Joshument 110 — 4y

I think .gsub is too weak for this, regex would work perfectly fine but regex itself is bigger than Lua itself. Either you can implement 4000 lines of regex yourself, or ignore them. Fifkee 2017 — 4y

Hello everyone, I know this reply is a year late but this is what I came up with:
local astring = [[
local a = {
"foo", -- fa fa fa fa fa
"bar"
}
]]
print(astring:gsub("--(-.-)\n","\n"))
This prints out:
local a = {
"foo",
"bar"
}

I'm a year late, yay.
We need it to ignore string formats because it will mess up the code, right?
This is the multi-lined version
local function GetMutliLinedComments(code)
local commentfound = false -- if the comments found then it will turn true
local start_ = 0 -- the start of the comment
local end_ = 0 -- the end of the comment
local sub = 0 -- its use is to get the next letter(or word)
local ignore = false -- if the function can ignore the comment inside a format
local comments = {}
code:gsub(".",function(c) -- usin gsub( well it's kinda bad cuz it has a limit
sub = sub + 1 -- what
if c == '"' then -- if it is a string format then
if ignore then
ignore = false
else
ignore = true
return -- not gonna do anything
end
end
if c == "'" then-- if it is a string format then
if ignore then
ignore = false
else
ignore = true
return
end
end
if code:sub(sub,sub+1) == "[[" and code:sub(sub-2,sub+1) ~= "--[[" then-- if it is a string format then
if ignore then
ignore = false
else
print(code:sub(sub-2,sub+1))
ignore = true
return
end
end
if not ignore then -- here comes the fun part
if code:sub(sub,sub+3) == "--[[" and commentfound == false then -- finds a comment format and no comments are found then
commentfound = true -- a comment is found!
start_ = sub
end
if code:sub(sub,sub+1) == "]]" and commentfound == true then -- finds teh end of a comment format and a comment format is found then
commentfound = false -- if it's the end of the format no comments are found
end_ = sub+1 -- just a little bug
table.insert(comments,code:sub(start_,end_)) -- inserts the comment format into a table
end
end
end)
return (comments) -- returns the table
end

String.match will work just fine here, just implement it correctly.
