Grab all of k before /n

[almost cool]

I have a tool tip set to k, and I need it to grab all information that goes before the /n like this.

"[I][B]Cost: $17[/B][/I]\nHealth: 20"

Then set it to a variable.

Any help would be appreciated.

[yakahughes]

local split = string.Explode("\n", k)
myvar = split[1]

[MakeR]

[lua]local var = k:match("(.-)\n")[/lua]

Now is there any way to flip that data (a string) into an integer?

Wait, that's not what you want. Give me a second.

[lua]local var = "Cost: $17\nHealth: 20"
for str in var:gmatch("[^n]+") do
local int = tonumber(string.Trim(string.sub(str , string.find(str , ":") + 1 , string.len(str)):gsub("$" , "")))
print(int)
end
[/lua]

Untested but shows the idea.

tonumber?

I think I overdid it.

[lua]local str = "Cost: $17\nHealth: 20"
local kv = {}

local function DoStuff( str )
for b in str:gmatch( "([^\n]+)" ) do
local k,v = b:match( "(%S+):%s*(%S+)" )
kv[k] = v
end
end
DoStuff( str )

print( kv["Cost"], kv["Health"] )[/lua]

None of these seem to work. Is there any other way, or can you explain these because my brain hurts.

[|FlapJack|]

Oh well. Fuck efficiency, let's go for clear, working code.

[lua]local str = "Cost: $17\nHealth: 20"

for k , v in ipairs(string.Explode("\n" , str)) do -- For each different newline character, do this
local bstr = string.sub(v , string.find(v , ":") + 1 , string.len(v)) -- Start at the position of : + 1 , end at the end of the string
local int = tonumber(string.Trim(bstr:gsub("$" , ""))) -- Replace $ with a blank character, then remove whitespaces at the end and start of the string.
end
[/lua]

bad argument #2 to 'tonumber' (base out of range)
said console.

what could i be doing wrong?

[|FlapJack|]

Try this.

[lua]local str = "Cost: $17\nHealth: 20"

for k , v in ipairs(string.Explode("\n" , str)) do -- For each different newline character, do this
local bstr = string.sub(v , string.find(v , ":") + 1 , string.len(v)) -- Start at the position of : + 1 , end at the end of the string
local int = tonumber(bstr:gsub("$" , "")) -- Replace $ with a blank character, then remove whitespaces at the end and start of the string.
end[/lua]

[almost cool]

Nothing changed.

[ralle105]

[lua]
local str = "Cost: $17\nHealth: 20"

for k,v in pairs(string.Explode("\n",str)) do
local _,_,num = v:find("^.+(%f)$") --%f is probably wrong, it should be th char for a number
num = tonumber(num)
end
[/lua]

It doesnt return any errors, but later on when I use:

if pl:GetNWInt("Cash") < num then

It returns saying that it cant compare a number to nil, so apparently that just returns with nothing.

and by the way, what are the _,_, for?

If you read the quote, I said that %f is most likely wrong. _,_ is the start and end positions returns from string.find, which we don't want:v:
