[SOLVED] How to get the string length?

[YounYokel]

Hey, is there a way to get a string length?
Like this:

Code: Select all

local textStr = "Hello World"
local textLen = textStr:getLength

function love.draw( dt )
    love.graphics.print( tostring( textLen ) ) -- Returns 11
end

Any of these methods work.

Code: Select all

-- all print 4
local str = "asdf"
print(#str)
print(string.len(str))
print(str:len())

This page lists the available string methods.

That said, the # operator is the preferred method, since iirc the others might be deprecated now.

Thank you! Didn't know about the hashtag.

There is a caveat to this.
If your string contains non-English characters you need to use UTF8 to the get the "real" length:

Code: Select all

local utf8 = require('utf8')
local str = "абвгд"
print(#str)
print(utf8.len(str))

Hash. Not hashtag. Let's not mix twitter functionality with what the character is called, please.
