Grab all of k before /n

Garry's Mod coding
#1

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

“Cost: $17
Health: 20”

Then set it to a variable.

Any help would be appreciated.

#2

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

#3

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

#4

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

#5

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

[lua]local var = "Cost: 17 Health: 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.

#6

tonumber?

#7

I think I overdid it.

[lua]local str = “Cost: $17
Health: 20”
local kv = {}

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

print( kv[“Cost”], kv[“Health”] )[/lua]

#8

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

#9

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

[lua]local str = “Cost: $17
Health: 20”

for k , v in ipairs(string.Explode("
" , 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]

#10

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

what could i be doing wrong?

#11

Try this.

[lua]local str = “Cost: $17
Health: 20”

for k , v in ipairs(string.Explode("
" , 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]

#12

Nothing changed.

#13

[lua]
local str = “Cost: $17
Health: 20”

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

Untested

#14

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?

#15

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:
